ABSTRACT
Objective To explore the effect of massage therapy guided by"corresponding compensa-tion"theory on the rehabilitation of shoulder joint function after radical resection in the patients with breast cancer.Methods Forty female patients with breast cancer after radical resection in Chongqing Municipal Hos-pital of Traditional Chinese Medicine during 2020-2022 were selected and divided into the group A and B ac-cording to the random number table method,20 cases in each group.The group A conducted the progressive functional exercise,and the group B received"corresponding compensation"massage combined with progres-sive functional exercise.Both of the two groups were treated for 20 d.Before treatment,on 20 d of treatment and after 3 months follow-up,the peak torque and total work of elbow joint flexor and extensor on the affected side were measured for evaluating the muscle force and endurance of the affected limb;the initiative joint mob-ility of anterior flexion,posterior extension,abduction and adduction of the affected shoulder joint was meas-ured to evaluate the shoulder joint mobility;the disabilities of the arm,shoulder and hand scale(DASH)was used to evaluate the degree of upper limb dysfunction;the swelling recovery of the upper limb was evaluated by measuring the difference of the circumference of the upper arm.The comparative analysis was conducted.Results On 20 d of treatment and after 3 months follow-up,the elbow flexion,extensor peak torque and total work on the affected side,and shoulder mobility in all directions on the affected side were improved in both groups,moreover these indicators in the group B were higher than those in the group A with statistically sig-nificant differences(P＜0.05);the DASH score and the circumference difference of the upper arm on the af-fected side all were decreased,moreover these indicators in the group B were lower than those in the group A with statistically significant differences(P＜0.05).Conclusion"Corresponding compensation"massage com-bined with progressive functional exercise could promote the rehabilitation of shoulder joint function after rad-ical resection in the patients with breast cancer.
ABSTRACT
Rotator cuff tears are very common in middle-aged and older adults and are the leading cause of shoulder surgery in the population. Some patients have rotator cuff tears that are classified as irreparable tears due to the large size of the tear and severe muscle atrophy. The treatment of irreparable rotator cuff tears presents great challenges. How to reconstruct the function of the shoulder joint is the key point. In this review article, authors will focus on partial repair of irreparable rotator cuff tears and tendon transfer for rotator cuff reconstruction, paying attention to its scope of application, efficacy, advantages and disadvantages, and providing reference for clinical diagnosis and treatment.
ABSTRACT
BACKGROUND:The shoulder joint,as a non-weight-bearing joint of the human upper limb,is considered a perfect compromise between flexibility and stability.The traditional experimental mechanics research of shoulder joints has some limitations due to the complexity of internal structure,measurement techniques and ethical issues.The finite element analysis method is applied to the research of shoulder joints,which provides valuable reference conclusions for the discussion of shoulder joint diseases and the decision of surgical methods. OBJECTIVE:To review the status of finite element research in the field of the shoulder joint,and to put forward the prospect of future research. METHODS:The finite element analysis method was used to search the literature on shoulder joint complex-related diseases in PubMed,Web of Science,WanFang and CNKI databases by computer.Chinese search terms were"shoulder joint,finite element analysis,rotator cuff injury,glenoid labrum,shoulder joint replacement".English search terms were"FE,should joint,glenohumeral joint,rotator cuff tears,glenoid labrum,shoulder arthroplasty".The search period was mainly from January 2010 to January 2023.Some important documents were also tracked,retrieved and read. RESULTS AND CONCLUSION:(1)With the open network of model data and the establishment of relevant model databases,finite element research has become more and more standardized and reproducible.(2)The widely validated finite element model of the shoulder joint deepens our understanding of the shoulder field to enable more efficient clinical decision-making.(3)With the continuous development of computer technology and software development,future finite element research is bound to become an indispensable practical tool for clinical scientific research.

ABSTRACT
Objective:To compare the clinical outcomes of arthroscopic external tension band fixation versus open reduction and internal fixation in the treatment of greater tubercle fracture of the humerus.Methods:A retrospective cohort study was conducted on 55 patients with greater tubercle fracture of the humerus admitted to Taizhou Hospital of Zhejiang Province from September 2019 to June 2022, including 24 males and 31 females, aged 26-80 years [(61.7±10.5)years]. Out of them, 35 patients treated with open reduction and internal fixation (open reduction group), and 20 patients were treated with external anchor tension band under arthroscopy (arthroscopy group). The operation time, and the Visual Analogue Scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score and shoulder active range of motion (anterior flexion, abduction and posterior extension) before operation, at 1 month after operation and at the last follow-up were compared between the two groups. Bone healing was observed in both groups at the last follow-up. Postoperative complications were compared between the two groups.Results:All the patients were followed up for 12-29 months [(16.9±4.0)months]. There was no significant difference in operation time between the two groups ( P>0.05). There were no significant differences in the VAS score, ASES score, Constant-Murley score and shoulder active range of motion between the two groups before operation ( P>0.05). The VAS score of the arthroscopy group was 3(2, 3)points at 1 month after operation, which was significantly lower than that of the open reduction group [4(3, 4) points] ( P<0.01). No significant difference was found in the VAS score at the last follow-up between the two groups ( P>0.05).The ASES scores of the arthroscopy group were (70.6±4.2)points and (90.2±3.7)points at 1 month after operation and at the last follow-up respectively, which were significantly higher than those of the open reduction group [(64.7±6.4)points and (87.5±4.9)points respectively] ( P<0.05 or 0.01). There was no significant difference in the Constant-Murley score between the arthroscopy group [(71.8±4.3)points] and the open reduction group [(70.9±5.3)points] at 1 month after operation ( P>0.05), while the Constant-Murley score of the arthroscopy group was (94.1±3.1)points at the last follow-up, which was significantly higher than that of the open reduction group [(89.2±4.7)points] ( P<0.01). At 1 month after operation and at the last follow-up, ranges of motion of the anterior flexion, abduction and posterior extension were (52.7±12.3)° and (140.0±16.9)°, (57.4±8.6)° and (125.0±14.3)°, and 16(15, 19)° and 25(20, 30)° in the arthroscopy group respectively, which were significantly higher than those in the open reduction group [(42.2±5.2)° and (110.9±14.0)°, (52.8±6.0)° and (103.7±11.7)°, and 10(10, 20)° and 16(15, 25)° respectively] ( P<0.05 or 0.01). At the last follow-up, it was found that bony union was achieved in both groups. There were no obvious complications such as incision infection or joint stiffnessin both groups. In the open reduction group, 2 patients had internal fixation failure within 1-3 months after operation but was treated with revision operation; 6 patients developed shoulder stiffness at 3-6 months after operation but had outpatient rehabilitation. The incidence rate of postoperative complications in the arthroscopy group [0%(0/20)] was significantly lower than that in the open reduction group [23%(8/35)] ( P<0.05). Conclusion:Compared with open reduction and internal fixation with plates and screws, arthroscopic external anchor tension band fixation in the treatment of greater tuberosity fracture of the humerus has the advantages of earlier pain relief, better shoulder functional improvement, better recovery of shoulder mobility, and fewer complications.
ABSTRACT
Objective:To investigate the clinical efficacy of repetitive transcranial magnetic stimulation (rTMS) versus functional electrical stimulation (FES) in the treatment of post-stroke complex regional pain syndrome. Methods:The randomized controlled study included 60 patients with post-stroke complex regional pain syndrome who received treatment at the Wenzhou TCM Hospital of Zhejiang Chinese Medical University from July 2021 to February 2023. These patients were divided into an rTMS group ( n = 30) and an FES group ( n = 30) using a random number table method. Patients in the rTMS group were treated with rTMS, while those in the FES group were treated with FES. All treatments were performed once daily for 8 consecutive weeks. The clinical efficacy, total active movement score of the fingers, Fugl-Meyer assessment scale score, Activity of Daily Living score, modified Barthel Index score, shoulder joint range of motion, and safety were compared between the two groups. Results:The total response rate in the FES group was 86.7% (26/30), which was significantly higher than 83.3% (25/30) in the rTMS group ( Z = 0.09, P = 0.93). After treatment, there were no significant differences between the two groups in terms of total active movement score of the fingers and Fugl-Meyer assessment scale score ( P = 0.244, 0.262). No significant differences were found between the two groups in MBI score and ADL score (both P > 0.05). There was also no significant difference in shoulder joint range of motion between the two groups ( P > 0.05). Conclusion:Both rTMS and FES are highly effective for post-stroke complex regional pain syndrome. They can improve upper limb function, enhance daily living abilities, and remodel neurological functions of the brain.
ABSTRACT
Objective To evaluate the short-term clinical effect of arthroscopic repair of rotator cuff injury with all-suture anchor using a prospective and single-cohort clinical trial.Methods Twenty-five patients with rotator cuff injuries(1.5 cm<tear size<6 cm)and admitted to the Department of Sports Medicine and Ambulatory Surgery Centre of Jiangsu Provincial Subei People's Hospital between July and September 2022 were used as the study subjects.Two cases were excluded for not meeting the in-clusion criteria,while another one was withdrawn halfway due to inconvenience of follow-up.Finally,22 patients were included in the study,consisting of 8 males and 14 females,with the average age of 59.1±10.9 years and rotator cuff tear size of 3.2±1.2 cm of 10 left and 12 right shoulders.Be-fore as well as 3 and 6 months after operation,all patients were evaluated using the pain visual ana-logue scale(VAS),the American Shoulder and Elbow Surgeons(ASES)score,Constant-Murley Shoul-der Functional(Constant)Score,Simple Shoulder Test(SST),bilateral shoulder abduction muscle strength ratio(affected/healthy),and mobility of the affected shoulder joint.Six months after operation,the healing of rotator cuff and the formation of cyst around the all-suture anchor were evaluated by us-ing the magnetic resonance imaging(MRI).According to whether there was cysts around the all-suture anchor,the patients were divided into the cyst group and the cyst-free group.Their age,sex,the side affected,trauma history,course time,tear size and operation time of the two groups were com-pared and analyzed to find the correlated factors.The average VAS,ASES and Constant scores,and the range of motion of the affected shoulder joint and the healing grade of rotator cuff were compared between the two groups 6 months after operation.Results Twenty-two patients were granted 6.2±0.3 months of follow-up after surgery.Three and six months after the operation,their average VAS scores(1.3±1.2 and 0.7±0.4),ASES scores(79.7±12.3 and 88.9±6.5),Constant scores(65.4±12.4 and 73.7±9.6),SST scores(7.6±0.2 and 10.5±0.2)and bilateral shoulder abductor muscle strength ratio(affected side/healthy side)(71.3±9.6 and 90.3±5.9)were significantly higher than the values before the opration(4.2±1.1,51.5±11.2,46.2±12.8,3.5±0.3 and 21.9±15.8),respec-tively(P<0.05).There were also significant differences in the range of motion of shoulder joint 3 months and 6 months after surgery(P<0.05).Postoperative MRI revealed 1 patient with rotator cuff re-tear.There was significant difference in age between the cyst group and the cyst free group(P<0.05).However,there was no significant difference in VAS score,ASES score,Constant score,range of mo-tion of shoulder joint and healing grade of rotator cuff between the two groups 6 months after surgery(P>0.05).Conclusion Arthroscopic rotator cuff repair with all-suture anchor is feasible and safe,and has good short-term clinical effect.
ABSTRACT
Abstract Objective There are few studies to date reporting on outcomes following reverse total shoulder arthroplasty with cohorts stratified by glenosphere size. The purpose of this study is to investigate the role that glenosphere size has on postoperative outcomes. Methods Patients who underwent reverse TSA between 1987 with minimum of 2.0 years of follow-up were included. Patients were stratified into two cohorts based on glenosphere size of 36mm or 40mm. Patients' range of motion, patient-reported outcomes, and radiographic variables (glenoid preoperative morphology, scapular notching, humeral loosening) were evaluated. Results All measurements of range of motion measurements with the exception of internal rotation saw significant preoperative to postoperative improvements within each cohort. There were no significant differences in postoperative range of motion, ASES, or VAS pain scores across the two cohorts. Overall, forward elevation improved to 134° ± 16° in the 36mm cohort and 133° ± 14° in the 40mm cohort (p = 0.47). External rotation improved to 37° ± 13° for 36mm patients and 35° ± 19° for 40mm patients (p = 0.58). In the 36mm group, internal rotation increased by 1.3 vertebral levels and 2.3 vertebral levels in the 40mm cohort. At final follow-up, the 36mm cohort had a VAS score of 2 ± 2, ASES score of 66 ± 19, and SST score of 6 ± 3. Similarly, the 40mm cohort had a VAS score of 2 ± 3, ASES score of 77 ± 28, and SST score of 9 ± 3. Conclusions Reverse TSA provides sustained improvements in range of motion and shoulder function irrespective of glenosphere size. Level of Evidence III.
Resumo Objetivo Até agora, poucos estudos relataram os desfechos da artroplastia total reversa (ATR) de ombro com coortes estratificadas pelo tamanho da glenosfera. O objetivo deste estudo é investigar o papel do tamanho da glenosfera nos desfechos pós-operatórios. Métodos O estudo incluiu pacientes submetidos à ATR de ombro desde 1987 com acompanhamento mínimo de 2,0 anos. Os pacientes foram estratificados em duas coortes com base no tamanho da glenosfera (36 mm ou 40 mm). A amplitude de movimento, os desfechos relatados pelo paciente e as variáveis radiográficas (morfologia pré-operatória da glenoide, incisura escapular e instabilidade do úmero) foram avaliados. Resultados Todas as medidas de amplitude de movimento, à exceção da rotação interna, melhoraram de forma significativa entre o período pré-operatório e pós-operatório nas duas coortes. Não houve diferenças significativas na amplitude de movimento pós-operatória, pontuação da American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) ou escala visual analógica (EVA) de dor entre as duas coortes. De modo geral, a elevação anterior melhorou para 134° ± 16° na coorte de 36 mm e 133° ± 14° na coorte de 40 mm (p = 0,47). A rotação externa melhorou para 37° ± 13° em pacientes da coorte de 36 mm e 35° ± 19° em pacientes da coorte de 40 mm (p = 0,58). A rotação interna aumentou 1,3 níveis vertebrais na coorte de 36 mm e 2,3 níveis vertebrais na coorte de 40 mm. No último acompanhamento, a coorte de 36 mm apresentou EVA de 2 ± 2, ASES de 66 ± 19 e pontuação do Simple Shoulder Test (SST) de 6 ± 3. Da mesma forma, a coorte de 40 mm teve EVA de 2 ± 3, ASES de 77 ± 28 e SST de 9 ± 3. Conclusões A ATR de ombro causa melhoras sustentadas da amplitude de movimento e função articular independentemente do tamanho da glenosfera. Nível de Evidência III.

Abstract Objective To provide a current overview of the Bristow-Latarjet surgery in Brazil. Materials and MethodsThis cross-sectional study was based on an electronic questionnaire with 26 items, which was sent to active members of the Brazilian Society of Shoulder and Elbow Surgery (Sociedade Brasileira de Cirurgia do Ombro e Cotovelo, SBCOC, in Portuguese). The questionnaire addressed training, surgical technique, complications, and postoperative management. Results We sent the questionnaire to 845 specialists from April 20 to May 12, 2021, and 310 of them answered i in full. During their specialization, most specialists participated in up to ten Bristow-Latarjet procedures. The most frequent complication was graft fracture, while the most common technical difficulty was screw positioning. In total, 50.6% and 73.9% reported having experienced intraoperative and postoperative complications respectively; 57.1% declared performing subscapularis suture; 99.7% indicated postoperative immobilization; and 61.9% considered graft consolidation fundamental. Conclusion Most specialists participated in up to ten Bristow-Latarjet procedures during the specialization, but 13.5% of them graduated without participating in the surgery. The most frequent complication was graft fracture. The most common technical difficulty was screw positioning. Most participants prefer postoperative immobilization since they believe graft consolidation is essential to resume the practiced of sports. The highest complication rate occurred with specialists who have obtained their titles 11 to 15 years ago. In Brazil, the Southeast region is the largest producer of specialists and has the highest concentration of these professionals.

The shoulder joint is the most flexible joint in the body with the largest range of motion, and the movement pattern is more complex. Accurate capture of three-dimensional motion data of the shoulder joint is crucial for biomechanical evaluation. Optical motion capture systems offer a non-invasive and radiation-free method to capture shoulder joint motion data during complex movements, enabling further biomechanical analysis of the shoulder joint. This review provides a comprehensive overview of optical motion capture technology in the context of shoulder joint movement, including measurement principles, data processing methods to reduce artifacts from skin and soft tissues, factors influencing measurement results, and applications in shoulder joint disorders.

Objective:To investigate the efficacy of shoulder arthroscopic balance point compaction with cross suture-bridge technique inr the treatment of avulsion fracture of the greater tuberosity of the humerus.Methods:A retrospective case series study was conducted on 14 patients with avulsion fracture of the greater tuberosity of the humerus treated in Affiliated Xinhua Hospital of Dalian University from March 2021 to March 2022, including 8 males and 6 females; aged 30-58 years [(40.2±10.5)years]. Among them, 5 patients had fracture in the left shoulder and 9 in the right shoulder. The fracture was classified as the avulsion type according to Mutch classification. All the patients were treated with shoulder arthroscopic balance point compaction with cross suture-bridge technique. The anteroposterior X-ray of the shoulder joint was taken at 1 week, 3 months, and 6 months after surgery to evaluate fracture reduction and fixation. The operative time and intraoperative blood loss were recorded. Fracture healing was evaluated by shoulder MRI at 6 months after surgery. The visual analog score (VAS), Constant shoulder joint score, American Shoulder and Elbow Surgeons (ASES) score, and shoulder range of motion (active abduction angle, active lateral external rotation angle, and active lateral internal rotation) preoperatively, at 3, 6 months after surgery and at the last follow-up were compared. The postoperative complications were observed.Results:All the patients were followed up for 12-15 months [(12.5±0.8)months]. The operative time and intraoperative blood loss were (67.0±10.5)minutes and (20.0±3.8)ml. The anteroposterior X-ray of the shoulder joint showed good reduction and fixation at 1 week, 3 months and 6 months after surgery. MRI T1 image at 6 months after surgery showed locally evenly distributed high signal, suggesting that the fracture was healed well. The values of VAS were (3.2±0.4)points, (2.5±0.5)points, and (0.7±0.3)points at 3, 6 months after surgery and at the last follow-up, which were lower than (7.2±0.6)points preoperatively; the values of Constant joint shoulder score were (53.2±5.3)points, (81.1±4.4)points, and (92.8±5.3)points, which were higher than (42.3±7.6)points preoperatively; the values of ASES score were (55.6±3.6)points, (77.1±3.2)points, and (90.8±3.5)points, which were higher than (45.8±4.2)points preoperatively; the active abduction angles were (60.5±2.5)°, (107.8±6.6)°, and (168.5±3.5)°, which were higher than (18.3±3.3)°preoperatively; the active lateral external rotation angles were (25.8±2.5)°, (30.8±2.2)°, and (63.8±2.8)°, which were higher than (15.6±3.2)°preoperatively ( P<0.05 or 0.01). The level of active internal rotation was L 5, L 1, and T 10, which was better than S 3 before surgery. The VAS, Constant shoulder joint score, ASES score, active abduction and active external rotation were significantly improved at the last follow-up compared with those at 3, 6 months after surgery (all P<0.05), with markedly improved level of active internal rotation. No major complications such as infection, instability of the shoulder joint or acromial impingement were found after surgery. Conclusion:Shoulder arthroscopic balance point compaction with cross suture-bridge technique for the treatment of avulsion fracture of the greater tuberosity of the humerus has advantages of decreased intraoperative blood loss, good reduction and healing, shoulder pain relief, early restoration of shoulder function and mobility, and few complications.
ABSTRACT
Objective:To compare the application effectiveness of conventional rehabilitation combined with thoracic spine mobility exercises and conventional rehabilitation in postoperative rehabilitation of patients with rotator cuff injury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 204 patients with rotator cuff injury admitted to First Affiliated Hospital of Jinan University from February 2019 to February 2022, including 88 males and 116 females; aged 18-87 years [(54.1±11.8)years]. Initial unilateral arthroscopic rotator cuff repair was performed on all the patients. A total of 98 patients received a conventional rehabilitation plan (conventional rehabilitation group), and 106 patients received additional thoracic spine mobility exercises as well as conventional rehabilitation (additional exercise rehabilitation group). The visual analog scale (VAS), Constant shoulder joint score, University of California at Los Angeles (UCLA) shoulder joint score, and shoulder range of motion (forward flexion, abduction, and external rotation) before surgery and at 1, 3, and 6 months after surgery were compared between the two groups. The occurrence of complications after rehabilitation was observed.Results:All the patients were followed up for 6-18 months [(8.4±3.5)months]. The VAS score, Constant shoulder joint score, UCLA shoulder joint score, and shoulder joint range of motion of both groups were improved significantly at 1, 3, and 6 months after surgery compared with those before surgery (all P<0.01). There was no statistically significant difference in VAS score between the two groups before surgery and at 1, 3, and 6 months after surgery respectively (all P>0.05). At 3 and 6 months after surgery, the values of the Constant shoulder joint score of the additional exercise rehabilitation group were (77.7±5.8)points and (88.4±7.7)points respectively, which were higher than those of the conventional rehabilitation group [(73.7±6.6)points and (85.5±4.9)points] (all P<0.01). There was no statistically significant difference in the Constant shoulder joint score between the two groups before and at 1 month after surgery (all P>0.05). At 3 months after surgery, the value of the UCLA shoulder joint score of the additional exercise rehabilitation group was (25.5±3.7)points, significantly higher than that of the conventional rehabilitation group [(21.8±5.6)points] ( P<0.01). There was no statistically significant difference in the UCLA shoulder joint score between the two groups before surgery and at 1 and 6 months after surgery (all P>0.05). At 3 and 6 months after surgery, the forward flexion angles of the additional exercise rehabilitation group were (135.5±12.8)° and (165.1±11.3)° respectively, which were higher than those of the conventional rehabilitation group [(129.3±12.3)° and (151.1±11.2)°]; the abduction angles of the additional exercise rehabilitation group were (102.3±12.9)° and (130.4±15.1)° respectively, which were higher than those of the conventional rehabilitation group [(93.2±11.0)° and (123.5±13.7)°]; the external rotation angles of the additional exercise rehabilitation group were (57.2±13.1)° and (72.3±12.3)°respectively, which were higher than those of the conventional rehabilitation group [(46.4±8.8)° and (67.4±14.1)°] (all P<0.01). There was no statistically significant difference in the forward flexion, abduction and external rotation angles between the two groups before surgery and at 1 month after surgery (all P>0.05). At 6 months after surgery, recurrent rotator cuff tear occurred in 1 patient (1.0%) in the conventional rehabilitation group and in 2 (1.9%) in the additional exercise rehabilitation group; shoulder joint adhesion deveplpoed in 5 patients (5.1%) in the conventional rehabilitation group and in 3 (2.8%) in the additional exercise rehabilitation group. No statistically significant difference was found in the incidence rate of postoperative complications between the two groups (all P>0.05). Conclusion:Compared with the conventional rehabilitation plan, addition of thoracic spine mobility exercise to the rehabilitation after arthroscopic repair surgery in patients with rotator cuff injury can achieve better joint function and range of motion, with no increase in the incidence of complications.
ABSTRACT
Objective:To compare the clinical effects of platelet-rich plasma (PRP) and sodium hyaluronate on rotator cuff injury.Methods:From February 2022 to December 2022, 226 patients with rotator cuff injury caused by military training were treated at Department of Orthopaedics, Jinling Hospital, School of Medicine, Nanjing University. They were all male, aged (24.5±3.7) years, and their time from injury to treatment was (4.6±2.2) months. They were divided into 2 even groups according to different treatments: an observation group of 113 cases into whose subacromial space PRP was injected, and a control group of 113 cases into whose subacromial space sodium hyaluronate was injected. In both groups, the injection was performed once a week for consecutive 3 weeks. The 2 groups were compared in terms of visual analogue scale (VAS) and Constant-Murley shoulder function scale (CMS) before treatment and 4 and 8 weeks after treatment, and the levels of TNF- α and IL-6 in the shoulder synovial fluid before treatment and 8 weeks after treatment. Results:There was no statistical difference between the 2 groups in general clinical data before treatment, indicating comparability ( P>0.05). At 4 and 8 weeks after treatment, compared with the pre-treatment values, the VAS scores were significantly decreased and the Constant-Murley scores significantly increased in both groups ( P<0.001). At 4 and 8 weeks after treatment, the VAS scores in the observation group (3.1±0.9 and 1.5±0.5) were significantly lower than those in the control group (3.7±0.8 and 2.3±0.6) while the Constant-Murley scores in the observation group (58.6±4.5 and 72.2±4.1) significantly higher than those in the control group (55.2±5.3 and 67.8±5.0) ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the 2 groups were significantly lower than the levels before treatment ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the observation group [(2.9±0.9) μg/L and (0.8±0.2) μg/L] were significantly lower than those in the control group [(4.0±0.4) μg/L and (1.1±0.4) μg/L] ( P<0.001). Conclusion:Injection of PRP or sodium hyaluronate can relieve pain and improve shoulder function obviously in patients with rotator cuff injury, but PRP is superior to sodium hyaluronate in the treatment of rotator cuff injury.
ABSTRACT
Objective:To compare proximal humerus internal locking system (PHILOS) and Multiloc intramedullary nail in the treatment of proximal humerus fracture-anterior dislocation.Methods:A retrospective study was performed to analyze the data of 33 patients with proximal humerus fracture-anterior dislocation who had been treated by open reduction and internal fixation from June 2015 to April 2021 at Department of Upper Limbs, Zhengzhou Orthopaedic Hospital. According to methods of internal fixation, the patients were divided into an extramedullary group and an intramedullary group. In the extramedullary group of 18 cases subjected to internal fixation with PHILOS, there were 8 males and 10 females with an age of (53.3 ± 10.6) years, and 1 2-part fracture, 15 3-part fractures and 2 4-part fractures by the Neer classification. In the intramedullary group of 15 cases subjected to internal fixation with Multiloc intramedullary nail, there were 8 males and 7 females with an age of (51.5 ± 11.2) years, and 14 3-part fractures and 1 4-part fracture by the Neer classification. The 2 groups were compared in terms of incision length, operation time, intraoperative blood loss, postoperative complications, and visual analog scale (VAS), range of shoulder motion, and Constant-Murley score at postoperative 12 months.Results:The 2 groups were comparable due to insignificant differences in their preoperative general data ( P>0.05). All patients were followed up for (20.8 ± 4.7) months. The incision length in the intramedullary group [(11.6 ± 1.7) cm] was significantly shorter than that in the extramedullary group [(17.6 ± 2.0) cm], and the intraoperative blood loss in the former [(106.7 ± 34.4) mL] was significantly lower than that in the latter [(151.7 ± 45.7) mL] ( P<0.05). The VAS scores at 1 week and 1 month after surgery [2.0 (2.0, 3.0) and 0.0 (0.0, 1.0) respectively] in the intramedullary group were significantly lower than those in the extramedullary group [3.0 (3.0, 3.3) and 1.0 (0.0, 1.3) respectively] ( P<0.05). The external rotation of the shoulder at the last follow-up in the intramedullary group (65.3° ± 15.5°) was significantly larger than that in the extramedullary group (50.6° ± 13.9°) ( P<0.05). There were no significant differences in operation time, incidence of postoperative complications, VAS score at 12 months after operation, Constant-Murley score or range of shoulder motion at the last follow-up between the 2 groups ( P>0.05). Conclusions:In the treatment of proximal humerus fracture-anterior dislocation, open reduction and internal fixation with both PHILOS and Multiloc intramedullary nail can result in a favorable prognosis when the fracture-dislocation is well reduced and fixated. However, the Multiloc intramedullary nail may lead to better early pain relief, less surgical invasion, and better functional recovery of the external rotation of the shoulder.
ABSTRACT
Objective:To explore the correlation between the anatomical features of shoulder joint and the re-tear rate after surgical repair for small and medium-sized rotator cuff tears.Methods:From June 2017 to June 2019, 55 patients who were diagnosed with small or medium-sized rotator cuff tears and treated with arthroscopic single-row repair were enrolled. Demographics including age, sex, disease course, history of smoking and diabetes mellitus, re-tear rates, Constant-Murley score, University of California, Los Angeles score (UCLA) at 6-month, 1-year, 2-year and 3-year after operation were collected. Postoperative critical shoulder angle (CSA) and acromial index (AI) were measured and calculated based on CT scan. The patients were divided into two groups: patients who got re-tear history during follow-up were included into endpoint re-tear (ER) group, and those who got no re-tear history during follow-up were included into endpoint non-tear (EN) group. One-way Anova was used to compare the CSA\AI among different follow-up point. Fisher's exact test was used to compare sex, morbidity of smoking and diabetes between the ER and EN groups. Two independent samples t-test were used to compare age, disease course, CSA and AI at 1-day after operation, functional scores at each follow-up point between the two groups. Binomial logistic regression analysis was performed to test CSA and AI at 1-day after operation as the risk factors of rotator cuff re-tear at 6-month, 1-year, 2-year and 3-year after operation. The predictive efficacy of CSA and AI at 1-day after operation on re-tear rate at 3-year after operation were evaluated by receiver operating characteristic (ROC) curves, Pearson correlation analysis was used to evaluate the correlation between postoperative CSA/AI and postoperative functional recovery. Results:The CSA and AI of ER group were insignificantly different among all follow-up point ( P>0.05), the CSA and AI of EN group were significantly different among all follow-up point ( F=14.163, P<0.001; F=4.635, P<0.001). The re-tear rates at 6-month, 1-year, 2-year and 3-year after operation were 3.6%, 7.3%, 12.7%, 18.2%. The Constant-Murley score and UCLA scores of ER group at 3-year after operation were 93.60±2.84 and 32.30±1.49, respectively while in EN group, they were 92.11±4.10 and 33.18±1.27, respectively, there were no difference of the Constant-Murley score and UCLA score between ER and EN group at 3-year after operation ( P>0.05). CSA at 1-day after operation was the risk factor to re-tear at 1-year, 2-year and 3-year after operation [ OR=4.622, 95% CI (1.01, 21.06), P=0.048; OR=7.071, 95% CI (1.52, 32.87), P=0.013; OR=3.40, 95% CI (1.42, 8.12), P=0.006]. CSA and AI at 1-day after operation had certain predictive efficacy for rotator cuff re-tear at 3-year after rehabilitation, and CSA was more specific than AI, the optimal cutoff values of CSA and AI at 1-day after operation for predicting rotator cuff re-tear at 3-year after operation were 35.3°and 0.69, the AUC were 0.87 [ OR=3.40, 95% CI (1.42, 8.12), P<0.001]、0.77 [ OR=1.33, 95% CI (0.87, 2.02), P=0.008] respectively. CSA and AI had no relationship with postoperative functional recovery. Conclusion:Greater CSA and AI were predictive factors of small and medium-sized rotator cuff re-tear 1-3 years after surgery with CSA being more specific than AI. However, CSA and AI had no relationship with postoperative functional recovery.
ABSTRACT
Objective:To investigate the clinical value of the modified lateral approach to the shoulder for the treatment of proximal humeral fractures.Methods:A total of 64 patients with proximal humeral fractures who received treatment in Zhoushan Branch, Ruijin Hospital, Shanghai Jiaotong University School of Medicine from May 2018 to May 2022 were included in this study. They were randomly divided into observation and control groups ( n = 32/group). The observation group was treated using a modified lateral approach to the shoulder. The control group was treated using the anteromedial approach to the shoulder. Perioperative indexes (operation time, intraoperative blood loss, postoperative drainage volume, hospital stay, and incision length) were compared between the two groups. Before surgery, 1 week and 3 months after surgery, the visual analogue scale score and the Constant-Murley shoulder assessment score were compared between the two groups. Before surgery and 3 months after surgery, the shoulder range of motion was compared between the two groups. The incidence of complications was also compared between the two groups. Results:The operation time, intraoperative blood loss, postoperative drainage volume, hospital stay, and incision length in the observation group were shorter or lower than those in the control group ( t = 7.42, 26.85, 10.90, 2.73, 10.59, all P < 0.05). At 1 week and 3 months after surgery, the visual analogue scale score in the observation group was significantly lower than that in the control group ( t = 5.80, 6.06, both P < 0.001). At 1 week and 3 months after surgery, the Constant-Murley shoulder assessment score in the observation group was (62.96 ± 12.05) points and (74.96 ± 14.52) points, respectively, which were significantly higher than (56.74 ± 9.62) points and (67.88 ± 12.25) points in the control group ( t = 2.28, 2.10, both P < 0.05). After surgery, the range of motion of the shoulder joint in the observation group was greater than that in the control group, including forward flexion, backward extension, external rotation, and internal rotation ( t = 2.54, 3.19, 2.40, 4.00, all P < 0.05). The incidence of complications in the observation group was 6.25% (2/32), which was significantly lower than 28.13% (9/32) in the control group ( χ2 = 5.39, P < 0.05). Conclusion:The modified lateral approach to the shoulder has a marked effect on proximal humeral fractures. The approach can improve shoulder function, shorten operation time, and decrease the incidence of complications.
ABSTRACT
Objective:To evaluate the shoulder arthroscopic treatment of avulsion fracture of humeral greater tuberosity with double-row suture bridge.Methods:Retrospectively analyzed were the 13 avulsion fractures of humeral greater tuberosity which had been treated by shoulder arthroscopic double-row suture bridge at Bone and Joint Department, Guangzhou Liwan District Orthopedic Hospital from March, 2018 to March, 2020. There were 6 males and 7 females, with an average ages of 52.3 years (from 35 to 69 years). According to the Mutch classification, all the fractures of humeral greater tuberosity were attributed to the avulsion type. Of them, 3 were simple avulsion fractures of humeral greater tuberosity and 10 were complicated with shoulder anterior dislocation which was reduced manually before operation. There were 3 obsolete avulsion fractures of humeral greater tuberosity. Regular clinic and X-ray follow-ups were carried out. At the final follow-up, the pain, range of motion (ROM) and stability of the shoulder joint were assessed using visual analogue scale (VAS), American shoulder elbow scores (ASES), and Korean shoulder scores (KSS).Results:All the patients were followed up for an average of 12.3 months (from 10 to 16 months) postoperatively. No infection or shoulder instability was observed. At the final follow-up, the abduction and elevation averaged 164.6° (from 135° to 180°), the lateral external rotation 62.7° (from 40° to 80°), the internal rotation touch back test T10 level (from L2 to T6), the VAS 0.65 (from 0 to 2.5), the ASES 90.5 (from 78 to 100), and the KSS 91.5 (from 84 to 100).Conclusion:Shoulder arthroscopic treatment of avulsion fracture of humeral greater tuberosity with double-row suture bridge is minimally invasive and allows for repair of combined injury, leading to quick postoperative recovery.
ABSTRACT
Objective:To explore the diagnosis and treatment of posterior shoulder dislocation combined with reverse Hill-Sachs lesion.Methods:Two male patients were treated at Department of Joint Surgery, Affiliated Hospital of Qingdao University for posterior shoulder dislocation combined with reverse Hill-Sachs lesion from August to November 2022. Case 1 was a 46-year-old man, admitted 1 day after right should injury, and case 2 a 57-year-old man, admitted 2 days after right should injury. The injury was caused by electric shock in both, and their fractures were fresh with an injury area>50%. After anatomical reduction of the collapsed humeral head via the pectoralis major deltoid approach, an artificial bone was implanted and fixated with countersunk screws in both cases to reduce the shoulder joint. The Constant-Murley scale and visual analogue scale (VAS) were used to evaluate the functional recovery of the shoulder and pain after treatment.Results:No such perioperative complications as incision infection, brachial plexus injury or vascular injury was observed in either of the 2 patients. Reexamination 3 months after surgery showed in case 1: 110° of shoulder anterior flexion, 90° of shoulder abduction, 30° of external rotation (neutral position), 70° of internal rotation (neutral position), 70 points of Constant-Murley shoulder score, and 3 points of VAS pain score; in case 2: 130° of shoulder anterior flexion, 120° of shoulder abduction, 50° of external rotation (neutral position), 80° of internal rotation (neutral position), 70 points of Constant-Murley shoulder score, and 2 points of VAS pain score.Conclusion:For patients with posterior shoulder dislocation complicated with reverse Hill-Sachs lesion and humeral head collapse greater than 50%, open reduction and screw internal fixation combined with artificial bone grafting can achieve good short-term curative efficacy.
ABSTRACT
Objective:To compare the clinical efficacy between reservation and sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear.Methods:A retrospective study was conducted to analyze the clinical data of 32 patients with rotator cuff tear plus remnants in the footprint area (2 cm < tear size <5 cm) who had been admitted to Department of Sports Medicine, The People's Hospital of Northern Jiangsu from May 2020 to July 2021. The patients were divided into 2 groups according to reservation or sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear. In the remnant-reservation group (16 cases): 5 males and 11 females with an age of (61.8±9.9) years, 9 left and 7 right shoulders affected, and (3.7±1.1) cm in size of rotator cuff tear; in the remnant-sacrifice group (16 cases): 4 males and 12 females with an age of (61.3±8.8) years, 8 left and 8 right shoulders affected, and (3.9±0.9) cm in size of rotator cuff tear. The 2 groups were compared in terms of visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley shoulder function score (Constant score), and range of motion of the affected shoulder before surgery, 3 months after surgery and at the last follow-up. The ratio of bilateral abductor muscle strengths (affected side/healthy side) was analyzed and compared between the 2 groups, and the healing of the rotator cuff was evaluated by MRI at the last follow-up.Results:The 2 groups were comparable because there were no significant differences in all their preoperative demographic data ( P>0.05). The 32 patients were followed up for (14.3±3.5) months after surgery. At 3 months after surgery, the VAS score in the remnant-reservation group [1.0 (0.0,1.0) point] was significantly lower than that in the remnant-sacrifice group [1.0 (1.0,1.0) point] ( P<0.05), but there was no significant difference between the 2 groups in ASES score, Constant score or range of motion of the affected shoulder ( P>0.05). At the last follow-up, the ASES score, forward flexion, abduction and ratio of bilateral abductor muscle strengths (affected side/healthy side) in the remnant-reservation group [(96.1±4.8) points, 170.0 (170.0,170.0)°, 160.0 (160.0,170.0)°, and 85.5%±13.8%]were significantly better than those in the remnant-sacrifice group [(91.4±5.9) points, 160.0 (160.0,170.0)°, 150.0 (140.0,155.0)°, and 72.6%±16.9%] ( P < 0.05), but there were no statistically significant differences between the 2 groups in VAS score, Constant score, neutral external rotation angle, or body-side internal rotation ( P>0.05). The Sugaya grading for MRI rotator cuff healing was significantly different between the 2 groups at the last follow-up ( P<0.05). Conclusion:In arthroscopic repair of rotator cuff tear, reservation of remnants in the footprint area can significantly relieve postoperative shoulder pain, and has obvious advantages in restoration of shoulder forward flexion, abduction and abductor muscle strength, leading to better healing of the rotator cuff and the large nodule than the remnant-sacrifice technique.
ABSTRACT
Objective:To compare the clinical effectiveness between arthroscopic hollow screws combined with a suture anchor, hollow screws and proximal humerus internal locking system (PHILOS) in the treatment of split-type fractures of humeral greater tuberosity.Methods:A retrospective study was conducted to analyze the 54 patients with split-type fracture of humeral greater tuberosity who had been admitted to Department of Joint Surgery, Hospital of Traditional Chinese Medicine, Affiliated to Southwest Medical University from May 2015 to August 2020. There were 17 males and 37 females with an age of (58.4±12.1) years. According to different treatment methods, they were divided into 3 groups. Group A of 18 cases was treated with arthroscopic hollow screws combined with a suture anchor, group B of 18 cases with hollow screws, and group C of 18 cases with PHILOS. The length of surgical incision, and range of shoulder motion, visual analogue scale (VAS), and American Shoulder and Elbow Surgeons (ASES) score at the last follow-up were recorded and compared between the 3 groups.Results:There was no statistically significant difference in the preoperative general information between the 3 groups, indicating the 3 groups were comparable ( P>0.05). The surgical incision in group A [(0.7±0.1) cm] was the shortest, followed by (5.0±1.4) cm in group B, and (12.8±2.1) cm in group C, showing statistically significant differences in pairwise comparison ( P<0.05). In the 3 groups at the last follow-up, respectively, the shoulder forward flexion was 159.7°±13.4°, 154.9°±16.2°, and 160.5°±12.9°, and the shoulder abduction 149.6°±11.3°, 142.4°±12.0°, and 145.1°±10.4°, showing no statistically significant difference among the 3 groups ( P>0.05); the external rotation was 41.1°±8.1°, 38.1°±7.8° and 43.7°±6.2°, showing a statistically significant difference between groups B and C ( P<0.05); the dorsal extension was T 12 (L 5 to T 6), T 12 (L 5 to T 7), and T 12 (L 3 to T 6), showing no statistically significant difference among the 3 groups ( P>0.05). There was no statistically significant difference among the 3 groups in the VAS score or ASES score at the last follow-up ( P>0.05). Respectively, there were 2, 6, and 4 patients in groups A, B and C who developed complications, showing statistically significant differences between the 3 groups ( P<0.05). Conclusions:In the treatment of split fractures of humeral greater tuberosity, arthroscopic hollow screws combined with a suture anchor, hollow screws and PHILOS can all relieve pain and restore joint function of the shoulder. However, arthroscopic hollow screws combined with a suture anchor are the most recommendable due to their advantages in minimally invasiveness and reduction in complications.
