ABSTRACT
OBJECTIVE@#To explore the mid-term effectiveness of arthroscopic "mini incision" transtendon repair for partial articular-sided supraspinatus tendon avulsion (PASTA) lesion.@*METHODS@#A clinical data of 39 patients with PASTA lesions, who underwent the arthroscopic "mini incision" transtendon repair and met the selected criteria between May 2017 and April 2021, was retrospectively analyzed. There were 13 males and 26 females, with an average age of 63.7 years (range, 43-76 years). Nine patients underwent trauma history, and no obvious inducement was found in the other 30 patients. The main clinical symptom was shoulder pain with positive hug resistance test. The interval from symptom onset to operation was 3-21 months (mean, 8.3 months). The visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, American Association of Shoulder and Elbow Surgeons (ASES) score and shoulder range of motion (ROM) of forward flexion, abduction, and external rotation were used to evaluate shoulder function. MRI was performed to assess the structural integrity and tension of reattached tendon. Patient satisfactions were calculated at last follow-up.@*RESULTS@#All incisions healed by first intention with no complications such as incision infection or nerve injury. All patients were followed up 24-71 months (mean, 46.9 months). The VAS, UCLA, and ASES scores significantly improved at 24 months after operation when compared with preoperative ones ( P<0.05). The ROMs of forward flexion and external rotation of the shoulder joint significantly increased at 3 and 24 months, and further increased at 24 months compared to 3 months, with significant differences ( P<0.05). However, the ROM of abduction of the shoulder joint at 3 months did not significantly improve compared with that before operation ( P>0.05), and it was significantly greater at 24 months than before operation and at 3 months after operation ( P<0.05). At last follow-up, the patients were very satisfied with the effectiveness in 30 cases (76.9%), satisfied in 5 cases (12.8%), and dissatisfied in 4 cases (10.3%). At 6 months after operation, 31 patients underwent reviews of MRI scans, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing, and 3 patients underwent tendon re-tear.@*CONCLUSION@#Arthroscopic "mini incision" transtendon repair in treatment of PASTA lesion could obtain satisfying mid-term effectiveness with low risk of tendon re-tear.

OBJECTIVE@#To investigate the feasibility and effectiveness of "tail compression fixation+suture bridge" technology under shoulder arthroscopy for treating primary tear in medial enthesis of rotator cuff.@*METHODS@#The clinical data of 11 patients with primary tear in medial enthesis of rotator cuff who met the selection criteria between October 2020 and October 2022 were retrospectively analyzed, including 3 males and 8 females, aged 39-79 years, with an average of 61.0 years. Rotator cuff injury was caused by traumatic fall in 8 cases, and the time from injury to admission was 1-4 months, with an average of 2.0 months; the remaining 3 cases had no obvious inducement. The active range of motion of the affected shoulder was limited, with an active forward flexion range of motion of (64.1±10.9)°, abduction of (78.1±6.4)°, internal rotation of (48.2±6.6)°, and external rotation of (41.8±10.5)°; 5 cases had shoulder stiffness. The preoperative visual analogue scale (VAS) score was 7.8±0.8 and the American Society of Shoulder and Elbow Surgeons (ASES) score was 23.9±6.4. The patients were treated with "tail compression fixation+suture bridge" technology under shoulder arthroscopy, and the pain and functional recovery were evaluated by VAS score, ASES score, and active range of motion of shoulder joint at last follow-up; MRI was performed after operation, and the integrity of rotator cuff was evaluated by Sugaya classification system.@*RESULTS@#All the 11 patients were followed up 2-22 months, with an average of 13.5 months. All incisions healed by first intention, and there was no complication such as infection, rotator cuff re-tear, and anchor falling off. At last follow-up, the VAS score was 0.8±0.7 and the ASES score was 93.5±4.2, which significantly improved when compared with those before operation ( P<0.05). All 11 patients had no significant swelling in the shoulders, and the active range of motion was (165.1±8.8)° in flexion, (75.3±8.4)° in abduction, (56.6±5.5)° in internal rotation, and (51.8±4.0)° in external rotation, which significantly improved when compared with those before operation ( P<0.05). Shoulder MRI showed adequate tendon thickness and good continuity in 9 cases, including 4 cases with partial high signal area; and 2 cases with inadequate tendon thickness but high continuity and partial high signal area. According to Sugaya classification system, there were 4 cases of type 1 (36.4%), 5 cases of type 2 (45.5%), and 2 cases of type 3 (18.1%).@*CONCLUSION@#For the patients with primary tear in medial enthesis of rotator cuff, the "tail compression fixation+suture bridge" technology under shoulder arthroscopy is simple and effective.

Rotator cuff injury is the most important cause of shoulder joint pain and dysfunction. In recent years, the incidence of rotator cuff injuries has gradually increased, reaching 30%-50% in people >50 years old. In the clinical treatment of rotator cuff injuries, suture anchors are widely used to fix the tendon to the bone and keep it in place without loosening or moderate tension until physiological healing is completed. The materials of suture anchors are constantly updated in clinical practice and have undergone the evolution of metal suture anchors, biodegradable suture anchors, biostable suture anchors, biocomposite suture anchors, and all suture anchors.This article reviews the advantages and disadvantages of anchors of various materials reported in domestic and foreign literatures.
ABSTRACT
Abstract Objective This study aimed to evaluate the nociceptive profile and the intake of analgesic drugs of patients submitted to rotator cuff repair surgery. Also, to evaluate the nociceptive thresholds and the integrity of the descending inhibitory system, pain catastrophism and prevalence of nociceptive or neuropathic pain. Methods Approved by the Ethics Committee of La Salle University (1.325.433/2015). 40 patients (>18 years old) who underwent rotator cuff repair surgery (divided in small and large injuries) were recruited. The used instruments were: Sociodemographic Questionnaire, Functional Pain Scale, Visual Analogue Scale (VAS), Quantitative Sensory Test (QST) and Conditioned Pain Modulation Task (CPM). Results Patients had a significant difference in pain thresholds QST heat (independent samples t test) and quality of sleep, mood and anxiety (paired t test) in groups preoperative. There was a significant correlation between preoperative CPM and postoperative VAS (Pearson Correlation). It was observed that, in preoperative, 38 patients used analgesics continuously. Besides that, in postoperative, use of opioid drugs was higher in patients with small injury (13 patients) than in those with large injury (9 patients). Conclusion Therefore, patients with rotator cuff injuries did not present alterations in the descending inhibitory system, but showed alterations in pain thresholds, which may interfere in the postoperative period and still be related to the consumption of analgesics.
Resumo Objetivo O objetivo deste estudo foi avaliar o perfil nociceptivo e o uso de analgésicos em pacientes submetidos à cirurgia de reparo do manguito rotador. Além disso, os limiares nociceptivos e a integridade do sistema inibidor descendente, o catastrofismo da dor e a prevalência de dor nociceptiva ou neuropática também foram analisados. Métodos Este estudo foi aprovado pelo Comitê de Ética da Universidade La Salle (1.325.433/2015). Quarenta pacientes (maiores de 18 anos) submetidos à cirurgia de reparo do manguito rotador (divididos entre aqueles com lesões pequenas e grandes) participaram do estudo. Os instrumentos utilizados foram o Questionário Sociodemográfico, a Escala Funcional de Dor, a Escala Visual Análoga (EVA), o Teste Sensorial Quantitativo (QST) e a Tarefa de Modulação Condicionada da Dor (CPM). Resultados Os pacientes apresentaram diferenças significativas nos limiares de dor e QST de calor (teste t de amostras independentes) e qualidade do sono, humor e ansiedade (teste t pareado) nos grupos pré-operatórios. Houve uma correlação significativa entre CPM pré-operatória e EVA pós-operatória (correlação de Pearson). Observou-se que, no período pré-operatório, 38 pacientes utilizavam analgésico de forma contínua. Além disso, no período pós-operatório, o uso de opioides foi maior nos pacientes com lesões pequenas (13 pacientes) em comparação àqueles com lesões grandes (nove pacientes). Conclusão Os pacientes com lesão do manguito rotador não apresentaram alterações no sistema inibidor descendente, mas sim alterações nos limiares de dor, o que pode interferir no período pós-operatório e estar relacionado ao consumo de analgésicos.

The patients were divided into two groups according to the treatment methods. The control group ( n = 48) was treated with ultrasound-guided adhesiolysis. The study group ( n = 55) was treated with ultrasound-guided adhesiolysis and intra-articular injection of platelet rich plasma. Therapeutic effects, pain score, shoulder function score, shoulder range of motion, healing rate, and re-tear rate were compared between the control and study groups. Results:Total effective rate was significantly higher in the study group than in the control group (96.36% vs. 81.25%, χ2 = 6.14, P < 0.05). Pain score in each group was significantly decreased after treatment compared with before treatment [study group: (1.69 ± 0.81) points vs. (6.13 ± 1.28) points; control group: (3.22 ± 1.05) points vs. (6.13 ± 1.28) points, t = 31.510, 8.33, both P < 0.001]. The University of California at Los Angeles (UCLA) shoulder score in each group was significantly increased after treatment compared with before treatment [study group: (33.26 ± 3.81) points vs. (14.03 ± 2.96) points; control group: (28.81 ± 3.20) points vs. (13.92 ± 3.03) points, t = 42.13, 33.12, both P < 0.001]. Constant-Murley Score in each group was significantly increased after treatment compared with before treatment [study group: (94.22 ± 4.15) points vs. (55.29 ± 8.18) points; control group: (82.11 ± 8.13) points vs. (56.33 ± 7.83) points; t = 46.83, 22.38, both P < 0.001]. After treatment, pain score was significantly lower in the study group than in the control group [(1.69 ± 0.81) points vs. (3.22 ± 1.05) points, t = 8.33, P < 0.001]. UCLA score and CMS were significantly higher in the study group than in the control group [(33.26 ± 3.81) points vs. (28.81 ± 3.20) points, (94.22 ± 4.15) points vs. (82.11 ± 8.13) points, t = 6.37, 9.70, both P < 0.001]. After treatment, there were improvements in flexion [study group: (159.26 ± 13.51)° vs. (85.26 ± 11.35)°; control group: (150.22 ± 14.35)° vs. (86.33 ± 11.51)°; t = 45.15, 34.23, both P < 0.001], internal rotation at 90° abduction [study group: (83.64 ± 5.29)° vs. (60.33 ± 4.12)°; control group: (76.81 ± 4.82)° vs. (60.61 ± 4.51)°; t = 36.74, 24.06, both P < 0.001], abduction [study group: (161.29 ± 10.76)° vs. (72.91 ± 5.16)°; control group: (152.81 ± 11.84) ° vs. (73.26 ± 5.22)°; t = 82.34, 64.61, both P < 0.001], external rotation at 90° abduction [study group: (87.82 ± 3.04)° vs. (4.29 ± 5.18)°; control group: (80.22 ± 4.13)° vs. (80.22 ± 4.13)°; t = 42.46, 21.55, both P < 0.001] , and external rotation in neutral position [study group: (43.18 ± 3.20)° vs. (22.85 ± 4.12)°; control group: (37.26 ± 4.12)° vs. (22.64 ± 3.95)°; t = 41.19, 25.10, both P < 0.001] in each group compared with before treatment. After treatment, range of motion of the shoulder in the above positions was significantly higher in the study group than in the control group [flexion: (159.26 ± 13.51)° vs. (150.22 ± 14.35)°; internal rotation at 90° abduction: (83.64 ± 5.29)° vs. (76.81 ± 4.82)°; abduction: (161.29 ± 10.76)° vs. (152.81 ± 11.84)°; external rotation at 90° abduction: (87.82 ± 3.04)° vs. (80.22 ± 4.13)°; external rotation in neutral position: (43.18 ± 3.20)° vs. (37.26 ± 4.12)°, t = 3.29, 6.81, 3.81, 10.72, 8.20, all P < 0.001]. There was no significant difference in healing rate between the study and control groups (1.82% vs. 16.67%, χ2 = 5.35, P < 0.05). Conclusion:Ultrasound-guided adhesiolysis combined with platelet-rich plasma is highly effective in the treatment of rotator cuff injuries because it can greatly improve shoulder function, reduce pain degree, and increase the range of motion of the shoulder.

ConclusionWarming needle moxibustion can further relieve shoulder pain in patients with rotator cuff injury, and improve shoulder ROM, muscle strength and functioning.
ABSTRACT
Objective To explore the effect of proprioceptive neuromuscular facilitation (PNF) rehabilitation training on functional recovery of athletic rotator cuff injury. Methods Twenty-two college students with athletic rotator cuff injuries were stratified according to their gender and randomly divided into resistance band + passive joint range of motion (ROM) training group (control group) and PNF training group (experimental group). The visual analog scale (VAS) was used to evaluate subjective pain intensity of the shoulder joint. Pain positive rate for each manipulation test of rotator cuff injury was observed, and active ROM and muscle strength of the shoulder joint were measured. Improved UCLA shoulder joint score was used to evaluate comprehensive function of the shoulder joint. Results After training, VAS scores and pain positive rate in two groups were lower than those before training, and VAS scores and pain positive rate in experimental group were lower than those in control group. Muscle strength, active ROM in all directions and improved UCLA score of the shoulder joint in two groups were also higher than those before training, and the internal rotation muscle strength, the internal rotation and external rotation active ROM, improved UCLA score of the shoulder joint in experimental group were higher than those in control group. Conclusions PNF rehabilitation training can reduce the pain of athletic rotator cuff injury, improve the active ROM, muscle strength and UCLA shoulder joint score. The function recovery effect of PNF training is better than that of resistance band + passive ROM training.
ABSTRACT
OBJECTIVE：To study the repa ir effect and mechanism of Taohong siwu decoction on rotator cuff injury in rabbits. METHODS：New Zealand rabbits were randomly divided into blank control group ，model group ，Taohong siwu decoction low-dose，medium-dose and high-dose groups （2.75，5.5，11 g/kg），and Taohong siwu decoction+LY 294002 group [ 5.5 g/kg Taohong siwu decoction+ 6.4 μg/kg LY294002（pathway inhibitor ）]，with 11 rabbits in each group. Except for blank control group ， other groups underwent right subscapularis muscle detachment to establish rotator cuff injury model. After modeling ，blank control group and model group were given normal saline intragastrically ；Taohong siwu decoction groups were given relevant medicine intragastrically；Taohong siwu decoction+LY 294002 group was given Taohong siwu decoction intragastrically ，and then injected with LY 294002 at the ear edge ，once a day ，for 12 weeks. After last intragastric administration （injection），the pathological changes of tendon-bone interface was observed ；the levels of TNF-α，IL-10 and IL- 6 in serum were detected ；mRNA and protein expressions of PI 3K，Akt and mTOR in tendon-bone interface were detected ；the expression of autophagy related protein （Beclin1， LC3Ⅱ）were detected. RESULTS ：Compared with blank control group ，the tendon-bone interface was uneven and the intima was swollen in model group. Serum levels of TNF-α and IL-6，mRNA and protein expressions of PI 3K，Akt and mTOR in tendon-bone interface were increased significantly （P＜0.05 or P＜0.01），while the level of IL- 10 and protein expression of Beclin 1 and LC 3Ⅱ were decreased significantly （P＜0.01）. Compared with model group ，the tendon-bone interface of rabbits in Taohong siwu decoction low-dose and medium-dose groups still had certain intimal damage ，while the tendon-bone interface of rabbits in high-dose group was smooth and flat without an obvious intimal tear ；the levels of most indexes in serum and tendon-bone interface of rabbits were significantly reversed in each dose group （P＜0.05 or P＜0.01）. Swollen tendon-bone interface and obvious intimal tear were obse rved in Taohong siwu decoction + LY group；compared with model group ，there w as no significant difference in above indexes of serum and tendon-bone interface （P＞0.05）. CONCLUSIONS ：Taohong siwu decoction may repair the rotator cuff injury of rabbits ，the mechanism of which may be associated with inhibiting PI3K/Akt/mTOR signaling pathway，activating autophagy and inhibiting inflammatory response.
ABSTRACT
Rotator cuff injuries are the most common cause of shoulder pain and dysfunction. Ideal animal shoulder models should have similar shoulder anatomy and function as human, and are able to replicate the microenvironment change after tendon injury. At present, a variety of animal models including rat, mouse, rabbit, sheep, canine, bovine, and primate have been used to study the mechanism of rotator cuff injury, effects of different repair techniques, and factors affecting tendon to bone healing. Although large animal models are more anatomically similar to humans, small animal models are more convenient in revealing the biological mechanism of rotator cuff injury and healing. Choosing appropriate animal models based on research objectives and establishing new small animal models play a critical role in revealing the mechanism of rotator cuff diseases and developing novel treating strategies.

ABSTRACT Introduction: Different studies relate the diagnosis of high-resolution ultrasound with the arthroscopic diagnosis of the rotator cuff. Both methods are favorable and show high sensitivity and specificity when they are compared. Objective: To establish diagnostic efficacy between the findings of high-resolution ultrasound and the arthroscopic diagnosis of partial and complete ruptures of the rotator cuff. Methods: A cross-sectional analytical study was carried out, aimed at evaluating the diagnostic efficacy of high-resolution ultrasound in patients of Dr. Antonio Luaces Iraola Provincial General Teaching Hospital, in Ciego de Ávila, with a clinical diagnosis of partial and complete ruptures of the rotator cuff, from January 2016 to January 2019. The universe consisted of 62 patients with a clinical diagnosis of rotator cuff rupture who presented surgical indications, and who were also indicated for an imaging study with high-resolution ultrasound and, subsequently, performed arthroscopic surgery, taken as a criterion of truth. Results: The male sex predominated, with an average age lower than those corresponding to female sex. The diagnostic findings by both methods showed agreement in more than two thirds of the patients who presented partial and complete ruptures of the rotator cuff's thickness. Ultrasonography, according to the method used, was an effective diagnostic tool for partial and complete ruptures of the rotator cuff's thickness. Conclusions: High-resolution ultrasound showed an adequate correlation in the diagnosis of partial or complete ruptures of rotator cuff, as confirmed by arthroscopy. It is considered an effective diagnostic means(AU)

BACKGROUND: Rotator cuff injury is the most common type of shoulder joint injury. So far, there are few studies on the relationship between local osteoporosis of the greater tuberosity of the humerus and rotator cuff tears in China. The bone mineral density (BMD) in the footprint area is a key factor affecting the intraoperative anchor placement. The recovery of BMD after operation is worth further study. OBJECTIVE: To compare preoperative and postoperative BMD of the bilateral greater tuberosity of the humerus and analyze the improvement of BMD after arthroscopic rotator cuff suture. METHODS: Data of 37 patients with unilateral rotator cuff injury who received arthroscopic suture in the Department of Joint Surgery of the Affiliated Hospital of Chengde Medical College were retrospectively analyzed. There were 16 males and 21 females. The average age was 55.8 years (age range: 35-73 years). Rotator cuff injuries were classified according to Patte’s degree of tendon retraction: mild retraction in 17 cases, moderate and severe retraction in 20 cases. BMD of the bilateral greater tuberosity of the humerus measured by dual-energy X-ray absorptiometry was collected, and the relationship between the course of disease, tendon retraction and the difference of BMD before and 1 year after surgery was analyzed. RESULTS AND CONCLUSION: The BMD difference of the bilateral greater tuberosity of the humerus in the mild retraction group was significantly lower than that in the moderate and severe retraction group (P < 0.05), and the BMD difference in the acute mild retraction group was significantly lower than that in the chronic moderate and severe retraction group (P < 0.05). The local osteoporosis of the greater tuberosity was severer in the patients with chronic moderate and severe retraction. During 1-year follow-up after surgery, the BMD difference of the 37 patients was significantly lower than that before surgery (P < 0.05). The BMD difference had no significant difference in the mild retraction group before and after surgery, while in the moderate and severe retraction group, the BMD difference was significantly lowered after surgery (P < 0.05). The BMD difference in the chronic moderate and severe retraction group was significantly lowered after surgery (P < 0.05). At the last follow-up, imaging examination showed no re-tears in all the enrolled patients. To conclude, local osteoporosis of the greater tuberosity is the most obvious in rotator cuff injury with chronic moderate to severe tendon retraction. Arthroscopic repair of rotator cuff injury under shoulder arthroscopy can restore local bone substance to a certain extent, regardless of the course of the disease.

BACKGROUND: The purpose of this study was to clarify the importance of preoperative pain control using corticosteroid injections in patients with persistent rest pain (RP) before arthroscopic rotator cuff repair (ARCR). METHODS: A total of 360 patients (374 shoulders) who underwent primary ARCR and were followed up for at least 2 years were enrolled. After one-to-one propensity score matching, 266 patients (145 men and 128 women, 273 shoulders) were included in the study. Their mean age was 65.2 ± 7.7 years (range, 42 to 88 years) at the time of surgery. The patients were divided into three groups: those who required several intra-articular or subacromial bursa corticosteroid injections preoperatively for refractory RP (group A+), those in whom RP was resolved preoperatively (group A−), and those who had no RP and did not require any injections (group B). The incidence of postoperative RP and preoperative and final follow-up American Shoulder and Elbow Surgeons (ASES) scores were compared among the three groups. RESULTS: The incidence of postoperative RP was significantly higher in group A+ (35/91 cases, 38.5%) than in group A− (10/91, 11.0%) and group B (7/91, 7.7%, p < 0.001 for both). The preoperative ASES score was significantly lower in group A+ (33.2 ± 14.2) than in group A− (53.9 ± 11.9) and group B (62.3 ± 11.2, p < 0.001 for both), and it was significantly lower in group A− than in group B (p = 0.000). The final follow-up ASES score was significantly lower in group A+ (92.1 ± 8.4) than in group A− (97.6 ± 5.4) and group B (99.0 ± 2.5, p < 0.001 for both). There was no significant difference in the final follow-up ASES score between group A− and group B (p = 0.242). CONCLUSIONS: Patients in whom preoperative RP could be resolved before surgery achieved postoperative outcomes comparable to those in patients who had no RP before surgery, whereas the outcomes in patients with refractory preoperative RP were inferior. The results suggest that preoperative pain control is important in patients undergoing ARCR.

Objective To investigate the activities of infraspinatus (IS) and posterior deltoid (PD) under shoulder external rotation at open kinetic chain (OKC) and closed kinetic chain (CKC) exercise with shoulder abduction 0° and 90° to determine the optimal external rotation rehabilitation exercise.Methods From April to June, 2018, 19 healthy adults finished the movement of 0° OKC, 0° CKC, 90° OKC and 90°CKC. The root mean square (RMS) of IS and PD was recorded with surface electromyography (sEMG), then the standardized RMS (RMS％), ratio of IS/PD and onset time of activation were calculated.Results RMS％ of PD was the minimal at 90° CKC, and was less than that of 0° CKC (P ＜ 0.05). IS/PD was the most at90° CKC, and was more than that of 90° OKC (P ＜ 0.05). The onset time of IS was the earliest in 90° CKC, and earlier than that of 90° OKC (P ＜ 0.05) and 0°OKC (P ＜ 0.05). The onset time of PD was the latest in 0° CKC, and latter than that of 90° OKC (P ＜ 0.05).Conclusion 90°CKC activates IS mostly and earliest, which can be used in early rehabilitation for rotator cuff injury.
ABSTRACT
ABSTRACT Objective: Shoulder pain, a common cause of productivity loss and health-related expense, is commonly due to rotator cuff tears. Magnetic resonance (MR) imaging with intra-articular gadolinium, MR arthrography, is accepted internationally as an excellent modality for evaluating the rotator cuff. Ultrasound is cheaper and only slightly less sensitive in detecting rotator cuff tears, but MR is superior in detecting ancillary lesions. Magnetic resonance arthrography was introduced at the University Hospital of the West Indies (UHWI), Jamaica, in July 2003. This study aimed to evaluate our experience with MR arthrography and assess its accuracy. Methods: A retrospective study was carried out. All MR arthrography cases performed at UHWI between July 2003 and July 2006 were reviewed. Medical records were reviewed to determine surgical correlation. Results: A total of 140 MR arthrograms were performed; 55% of the patients were female. Ages ranged from the second to the ninth decade, having a distribution approaching but not attaining a normal distribution (p = 0.03) with clustering in the middle years. Magnetic resonance arthrography demonstrated torn rotator cuffs in 40 patients, none of whom was under the age of 40 years (p < 0.001). Fifteen patients had surgery which confirmed torn rotator cuffs in all 15. Conclusion: Magnetic resonance arthrography was found to be accurate in detecting rotator cuff tears. It should be considered in the evaluation of patients with suspected rotator cuff tears. For patients under the age of 40 years, sonography could be used as an alternative.
RESUMEN Objetivo: El dolor en el hombro, el cual es causa común de pérdida de productividad y gastos relacionados con la salud, se debe comúnmente a desgarros del manguito rotador. La imagen por resonancia magnética (IRM) con gadolinio intra-articular - conocida como artrografía RM - se acepta internacionalmente como una excelente modalidad para evaluar el manguito rotador. El ultrasonido es más barato y sólo ligeramente menos sensible a la hora de detectar desgarros del manguito rotador, pero la RM es superior en la detección de lesiones secundarias. La artrografía por resonancia magnética se introdujo en el Hospital Universitario de West Indies (HUWI), Jamaica, en julio de 2003. Este estudio tuvo como objetivo evaluar nuestra experiencia con la artrografía RM y evaluar su precisión. Métodos: Se realizó un estudio retrospectivo. Se revisaron todos los casos de artrografías RM realizadas en HUWI entre julio de 2003 y julio de 2006. Se revisaron las historias clínicas a fin de determinar la correlación quirúrgica. Resultados: Un total de 140 artogramas RM fueron realizados. El 55% de los pacientes eran mujeres. Las edades variaron del segundo al noveno decenio, con una distribución que se acercaba pero no llevaba a alcanzar una distribución normal (p = 0.03), concentrándose en los años intermedios. La artrografía de resonancia magnética mostró desgarros de los manguitos rotadores en 40 pacientes, ninguno de los cuales tenía menos de 40 años (p < 0.001). Quince pacientes tuvieron cirugía que confirmaba desgarros de los manguitos rotadores en los 15. Conclusión: Se halló que la artrografía por resonancia magnética era exacta a la hora de detectar los desagarros del manguito rotador. Debe considerarse en la evaluación de pacientes con sospecha de desgarros del manguito rotador. Para los pacientes menores de 40 años de edad, la sonografía podría ser utilizada como alternativa.

Objective:To investigate the diagnostic value of 1.5T magnetic resonance imaging(MRI) and multi-slice spiral CT (MSCT) for subacromial impingement syndrome(SIS).Methods: The clinical data of 60 patients with SIS were researched by using retrospective analysis. All of patients were detected by using MRI and CT, respectively. And the diagnosis value of the two methods were compared.Results: The differences of sensitivity and Youden index between MRI and MSCT were significant, respectively (x2=12.987,x2=12.987,P<0.05), and the diagnostic sensitivity of MRI was higher than that of MSCT. While the diagnostic specificities of the two method were 100％. The differences of detectable rate for Bigliani I and Bigliani II between MRI and MSCT were no significant (x2=2.492,x2=2.031, P>0.05), respectively. The detectable rate of MRI for Bigliani III was significantly higher than that of MSCT (x2=9.087, P<0.05).Conclusion: The diagnostic sensitivity of MRI for SIS is higher than that of MSCT, and the main reason is that MRI has higher resolution ratio for soft tissue. Besides, it has no radiation. Therefore, it is appropriate to the diagnosis of SIS.
ABSTRACT
Rotator cuff injury is a common shoulder disease,which often results in pain and limited motion of shoulder and reduces the quality of life.There are some limitations for current treatments,which often lead to repair failure or reinjury of rotator cuff.Therefore,a novel repair technique is needed.Biologic repair represents a novel technique in the management of rotator cuff injury,and has the potential to restore the normal histological structure of rotator cuff.Biologic repair involves the application of growth factors and/or cells to promote the regeneration of rotator cuff tendons. This study reviewed the literatures on biologic repair of rotator cuff injury,and presented the research progress.
ABSTRACT
Objective To compare the effects of early passive motion(EPM)and delayed passive motion (DPM)on joint range of motion(ROM),joint function and recurrent tears after arthroscopic rotator cuff repair. Methods A total of 84 cases with middle or large rotator cuff injury were randomly divided into EPM group(43 cases)and DPM group(41 cases). EPM group began shoulder rehabilitation exercise on the first day post-opera-tion and DPM group began 6 weeks later. ROM,pain and function of shoulder joint were evaluated before and 3,6 and 12 months after operation. Results ASES score and UCLA score in EPM group were significantly higher than those in DPM group at 3 months postoperatively(P < 0.05). There was no significant difference in joint ROM,pain and functional between two groups at 6 months and 12 months postoperatively(P > 0.05). There was no statistically significant difference in recurrent tears between two groups at least 12 months follow-up. Conclusion There was no significant difference in functional outcomes,ROM and relative risks of recurrent tears between EPM and DPM in patients undergoing arthroscopic rotator cuff repairs. EPM is conducive to joint ROM and function rapid recovery postoperatively and does not increase the risks of recurrent tears.
ABSTRACT
<p><b>OBJECTIVE</b>To verify the clinical therapeutic effects on shoulder joint pain of rotator cuff injury treated with electroacupuncture (EA) and Mulligan's mobilization.</p><p><b>METHODS</b>A total of 120 patients of shoulder joint pain of rotator cuff injury were randomized into an EA group, a rehabilitation group and a combined therapy group, 40 cases in each one. In the EA group, EA was applied to Jianzhen (SI 9), Jianliao (TE 14), Jianyu (LI 15), Tianzong (SI 11), Jianqian (extra) and Binao (LI 14) in the affected side. Of these acupoints, Jianliao (TE 14) and Jianyu (LI 15), Jianzhen (SI 9) and Tianzong (SI 11) were stimulated with's electric apparatus. In the rehabilitation group, Mulligan's mobilization was used, including scapular mobilization, static joint mobilization and dynamic joint mobilization. In the combined therapy group, EA was used in combination with Mulligan mobilization. The treatment was given once a day in each group, 5 sessions a week, totally for 6 weeks. The pain intensity of shoulder joint (VAS), the University of California at Los Angeles shoulder rating scale (UCLA) and the range of motion (ROM) of shoulder joint were evaluated before and 6 weeks after treatment separately. The adverse reactions were recorded in each group.</p><p><b>RESULTS</b>VAS scores were all reduced, UCLA scores increased and ROM improved after treatment as compared with those before treatment in the patients of the three groups (all<0.05). After treatment, VAS score, UCLA score and ROM in the combined therapy group were remarkably improved as compared with those in the EA group and the rehabilitation group (all<0.05). Regarding the improvements of VAS and UCLA scores, the results in the EA group were better than those in the rehabilitation group (both<0.05). Regarding ROM improvement, the results in the rehabilitation group were superior to those in the EA group (all<0.05). There was no adverse reaction in the two groups.</p><p><b>CONCLUSION</b>The combined therapy of EA and Mulligan's mobilization relieves shoulder joint pain of rotator cuff injury, better than the simple application of either EA or Mulligan's mobilization.</p>
