ABSTRACT

Abstract Objective To validate the low-cost model for arthroscopy training and analyze the acceptance and usefulness of the developed simulator in medical teaching and training. Method Ten medical students, ten third-year orthopedic residents, and ten shoulder surgeons performed predetermined tasks on a shoulder simulator twice. The parameters used were time to complete the tasks, number of looks at the hands, GOALS score (Global Operative Assessment of Laparoscopic Skills) and comparison between groups and within groups. An adapted Likert scale was applied addressing the individuals' impressions about the simulator and its applicability. Results In the intergroup comparison, the shoulder surgeons had better scores and times than the other groups. When the tasks were repeated, the group of surgeons had a 59% improvement in time (p < 0.05), as did the group of medical students. In the GOALS score, shoulder surgeons had consistently better scores than the other groups. And when we evaluated the evolution from the first to the second test, the group of surgeons and the group of academics had a statistically significant improvement (p < 0.05). In terms of lookdowns, there was a decrease in all groups. There was consensus that the simulator is useful in training. Conclusion The simulator developed allowed the differentiation between individuals with different levels of training in arthroscopic surgery. It was accepted by 100% of the participants as a useful tool in arthroscopic shoulder surgical training.


Resumo Objetivo Validar o modelo de baixo custo para treinamento em artroscopia e analisar a aceitação e utilidade do simulador desenvolvido no ensino e treinamento médico. Método Dez acadêmicos do curso de medicina, dez residentes do terceiro ano em ortopedia e dez cirurgiões de ombro realizaram tarefas pré determinadas em um simulador de ombro duas vezes. Os parâmetros utilizados foram o tempo para completar as tarefas, quantidade de olhares para as mãos, escore de GOALS (Global Operative Assessment of Laparoscopic Skills) e comparados entre os grupos e intragrupos. Uma escala de Likert adaptada foi aplicada abordando as impressões dos indivíduos acerca do simulador e de sua aplicabilidade. Resultados Na comparação intergrupos, os cirurgiões de ombro tiveram melhores escores e tempos que os demais grupos. Quando as tarefas foram repetidas, o grupo de cirurgiões, teve uma melhora de 59% no tempo (p < 0,05), assim como no grupo de acadêmicos. No escore de GOALS os cirurgiões de ombro apresentaram escores consistentemente melhores que os demais grupos. E quando avaliamos a evolução do primeiro para o segundo teste, o grupo de cirurgiões e o grupo de acadêmicos tiveram melhora estatisticamente significante (p < 0,05). No quesito de lookdowns houve diminuição em todos os grupos. Houve consenso em que o simulador é útil no treinamento. Conclusão O simulador desenvolvido permitiu a diferenciação entre indivíduos com diferentes níveis de treinamento em cirurgia artroscópica. Foi aceito por 100% dos participantes como uma ferramenta útil no treinamento cirúrgico artroscópico do ombro.

ABSTRACT

Abstract Objective The present study aims to analyze the use of shoulder imbalance as a parameter for scoliosis screening as well as its relationship with other parameters of physical examination. Methods This study assesses a smartphone application that analyzes several parameters of the physical examination in adolescent idiopathic scoliosis. Medical and non-medical examiners applied the screening tool in students in a public school and in a private sports club. After data collection, interobserver correlation was done to verify shoulder imbalance and to compare shoulder imbalance with Adam's bending test and with trunk rotation. Results Eighty-nine participants were examined, 18 of whom were women and 71 of whom were men. Two subjects were excluded from the analysis. The mean age of subjects from the public school was 11.30 years and, for those from the sports club, it was 11.92 years. The examiners had poor-to-slight interobserver concordance on shoulder asymmetry in the anterior and posterior view. No significant statistical correlation was found between shoulder asymmetry and positive Adam's forward bending test. Conclusion Our preliminary study shows that the shoulder asymmetry has a poor correlation with the Adam's forward bending test and measuring trunk rotation using a scoliometer. Therefore, the use of shoulder imbalance might not be useful for idiopathic scoliosis screening. Level of Evidence III; Diagnostic Study


Resumo Objetivo O objetivo deste estudo é analisar o uso da assimetria de ombros como parâmetro para a triagem de escoliose e sua relação a outros parâmetros do exame físico. Métodos Este estudo avalia um aplicativo para smartphone que analisa diversos parâmetros do exame físico de adolescentes com escoliose idiopática. Examinadores médicos e não médicos utilizaram o instrumento de triagem em alunos de uma escola pública e de um clube esportivo privado. Após a coleta de dados, a correlação interobservador foi determinada para verificar a assimetria de ombros e compará-la ao teste de inclinação de Adam e à medição da rotação do tronco. Resultados Oitenta e nove participantes foram examinados, sendo 18 do sexo feminino e 71 do sexo masculino. Dois indivíduos foram excluídos da análise. A média de idade dos participantes da escola pública foi de 11,30 anos e do clube esportivo, 11,92 anos. Os examinadores apresentaram concordância interobservador baixa a branda quanto à assimetria de ombros em incidência anterior e posterior. Não houve correlação estatística significativa entre a assimetria de ombros e o resultado positivo no teste de inclinação do tronco de Adam. Conclusão Nosso estudo preliminar mostra que a assimetria de ombros tem baixa correlação com o teste de inclinação de Adam e assim como com a medição de rotação do tronco com escoliômetro. Portanto, o uso da assimetria de ombros pode não ser útil na triagem da escoliose idiopática. Nível de Evidência III; Estudo Diagnóstico

ABSTRACT

Abstract In five patient undergoing surgery for proximal humerus fracture we investigated into postoperative analgesia provided by continuous costoclavicular block using continuous stimulating catheter. The postoperative pain scores were less than 4 in all patients except in two patients who required intravenous tramadol 50 mg as a rescue analgesic. The radiocontrast dye study executed in two patients revealed contiguous contrast spread through the brachial plexus sheath with the catheter tip in the interscalene space. We propose that a continuous costoclavicular block with a retrograde stimulating catheter is a feasible alternative regional anesthesia technique for postoperative analgesia in shoulder surgery.

ABSTRACT

Abstract Objective Rotator cuff repair (RCR) is one of the most common arthroscopic procedures. Our investigation aims to quantify the impact that the COVID-19 pandemic had on RCR, specifically on patients with acute, traumatic injuries. Methods Institutional records were queried to identify patients who underwent arthroscopic RCR between March 1st to October 31st of both 2019 and 2020. Patient demographic, preoperative, perioperative, and postoperative data were collected from electronic medical records. Inferential statistics were used to analyze data. Results Totals of 72 and of 60 patients were identified in 2019 and in 2020, respectively. Patients in 2019 experienced shorter lengths of time from MRI to surgery (62.7 ± 70.5 days versus 115.7 ± 151.0 days; p = 0.01). Magnetic resonance imaging (MRI) scans showed a smaller average degree of retraction in 2019 (2.1 ± 1.3 cm versus 2.6 ± 1.2 cm; p = 0.05) butnodifference in anterior toposterior tear size between years (1.6 ± 1.0 cm versus 1.8 ± 1.0 cm; p = 0.17). Less patients in 2019 had a tele-health postoperative consultation with their operating surgeon compared with 2020 (0.0% versus 10.0%; p = 0.009). No significant changes in complications (0.0% versus 0.0%; p > 0.999), readmission (0.0% versus 0.0%; p > 0.999), or revision rates (5.6% versus 0.0%; p = 0.13) were observed. Conclusion From 2019 to 2020, there were no significant differences in patient demographics or major comorbidities. Our data suggests that even though the time from MRI to surgery was delayed in 2020 and telemedicine appointments were necessary, RCR was still performed in a time in early complications. Level of Evidence III.


Resumo Objetivo Oreparodomanguitorotador (RMR) é um dos procedimentos artroscópi-cos maiscomuns. Nossapesquisavisaquantificar o impacto da pandemia de COVID-19 sobre o RMR, especificamente em pacientes com lesões agudas e traumáticas. Métodos Os prontuários institucionais foram consultados para identificação de pacientes submetidos ao RMR artroscópico entre 1° de março e 31 de outubro de 2019 e de 2020. Dados demográficos, pré-operatórios, perioperatórios e pós-operatórios dos pacientes foram coletados de prontuários eletrônicos. Os dados foram analisados por estatística inferencial. Resultados Totais de 72 ede60pacientes foramidentificados em 2019 e 2020, respectivamente. Os pacientes de 2019 apresentaram menor intervalo entre a ressonância magnética (RM) e a cirurgia (62,7 ± 70,5 dias versus 115,7 ± 151,0 dias; p = 0,01). Os exames de RM mostraram menor grau médio de retração em 2019 (2,1 ± 1,3 cm versus 2,6 ± 1,2 cm; p = 0,05), mas nenhuma diferença foi observada na extensão anteroposterior da laceração entre os anos (1,6 ± 1,0 cm versus 1,8 ± 1,0 cm; p = 0,17).Em 2019,o número de pacientes atendidos por seus cirurgiões em consultas pós-operatórias por telemedicina foi menor em comparação com 2020 (0,0% versus 10,0%; p = 0,009). Não foram observadas alterações significativas nas taxas de complicação (0,0% versus 0,0%; p > 0,999), de readmissão (0,0% versus 0,0%; p > 0,999) ou de revisão (5,6% versus 0,0%; p = 0,13). Conclusão Não houve diferenças significativas nos dados demográficos dos pacientes ou nas principais comorbidades entre 2019 e 2020. Nossos dados sugerem que, embora o intervalo entre a RM e a cirurgia tenha sido maior em 2020 e tenha havido necessidade de consultas por telemedicina, o RMR ainda foi realizado em tempo hábil e sem alterações significativas nas complicações precoces. Nível de Evidência III.

ABSTRACT

Abstract Objective Research and identification of Cutibacterium acnes (C. acnes) and other microorganisms in deeptissue samples collected in clean shoulder surgeries of patients who did not undergo any previous invasive joint procedure and who had no clinical history of infection. Methods We analyzed the results of cultures of intraoperative deep tissue samples from 84 patients submitted to primary clean shoulder surgery. Tubes containing culture medium were used for storage and transport of anaerobic agents, prolonged incubation time, and mass spectrometer for diagnosis of bacterial agents. Results Bacteria growth was evidenced in 34 patients (40.4%) of the 84 included in the study. Of these, 23 had growth of C. acnes in at least one sample of deep tissue collected, corresponding to 27.3% of the total patients. The second most common agent was Staphylococcus epidermidis, present in 7.2% of the total individuals included. We showed a higher relationship between sample positivity and males, a lower mean age, absence of diabetes mellitus, ASA I score, and antibiotic prophylaxis in anesthetic induction with cefuroxime. Conclusions A high percentage of isolates of different bacteria was found in shoulder tissue samples of patients undergoing clean and primary surgeries, who had no history of previous infection. Identification of C. acnes was high (27.6%), and Staphylococcus epidermidis was the second most frequent agent (7.2%).

ABSTRACT

Abstract Objective Adhesive capsulitis is a condition characterized by shoulder pain and stiffness. Breast cancer treatment has been linked to the development of this condition, but its mechanisms are still little known. This study's objective was to identify predictors factors associated with the development of adhesive capsulitis in breast cancer patients. Methods A case control study was performed with women undergoing treatment for breast cancer in a single center. The sampling was nonprobabilistic and consecutive. Adhesive capsulitis was defined as constant pain associated with decreased active and passive shoulder movement in anterior elevation, external rotation at 0°/90° abduction, and internal rotation at 90° abduction. The study group consisted of patients with shoulder pain and range of motion limitations, while the control group consisted of women without any shoulder abnormalities. Sociodemographic and clinical variables were collected. A univariate logistic regression was used to assess the influence of variables on the studied outcome. For p< 0.20, a multivariate logistic regression was used. The probability of null hypothesis rejection was 5%. Results A total of 145 women were assessed, with 39 (26.9%) on the study group and 106 (73.1%) on the control group. The majority was under 60 years old. In the multivariate analysis, variables correlated to the outcome under study were shoulder immobilization (OR = 3.09; 95% CI: 1.33-7.18; p= 0.009), lymphedema (OR = 5.09; 95% CI: 1.81-14.35; p= 0.002), and obesity (OR = 3.91; 95% CI: 1.27-12.01; p= 0.017). Conclusion Lymphedema, postsurgery immobilization, and obesity are predictive factors for the development of adhesive capsulitis in breast cancer patients.


Resumo Objetivo Capsulite adesiva é uma afecção caracterizada por dor e limitação dos movimentos do ombro. O tratamento do câncer de mama está relacionado ao desenvolvimento dessa doença por meio de mecanismos ainda pouco conhecidos. O objetivo do estudo foi identificar os fatores associados ao desenvolvimento de capsulite adesiva em pacientes com câncer de mama. Métodos Um estudo caso-controle foi realizado com mulheres em tratamento para câncer de mama em um centro único. A amostra foi consecutiva e não-probabilística. A capsulite adesiva foi pré-definida como dor constante e diminuição da amplitude de movimentos em elevação anterior, rotação externa em 0°/90° abdução e rotação interna em 90° abdução. O grupo caso foi constituído por pacientes com dor e limitação de todos os movimentos do ombro, enquanto o controle por pacientes sem qualquer alteração nesta articulação. Variáveis sociodemográficas e clínicas foram coletadas. Foi realizada uma análise de regressão logística univariada para avaliar a influência das variáveis em relação ao desfecho estudado. Para valores de p< 0,20, realizou-se a análise de regressão logística multivariada. A probabilidade de se rejeitar a hipótese nula foi de 5%. Resultados Foram avaliadas 145 mulheres, sendo 39 casos (26,9%) casos e 106 controles (73,1%). Na análise multivariada, as variáveis associadas ao desfecho estudado foram imobilização do ombro (OR = 3,09; 95% IC: 1,33-7,18; p= 0,009), linfedema (OR = 5,09; 95% IC: 1,81-14,35; p= 0,002) e obesidade (OR = 3,91; 95% IC: 1,27-12,01; p= 0,017). Conclusão Linfedema, imobilização pós-cirúrgica e obesidade são fatores preditores associados ao desenvolvimento de capsulite adesiva em pacientes com câncer de mama.

ABSTRACT

Abstract Objective This study assesses the relationship between the glenoid bone loss size and range of motion, functional outcomes, and complications in high-performance athletes undergoing bone block surgery for anterior shoulder instability. Methods This retrospective study evaluated postoperative outcomes in athletes submitted to bone block surgery for anterior shoulder instability. In 5 years, 41 shoulders underwent the procedure; 20 had bone losses up to 15%, and 21 shoulders presented bone losses ranging from 15% and 25%. Results There was no statistically significant difference regarding postoperative complications, new dislocations, and the rate of return to sports. In addition, the quantitative criteria evaluated, i.e., ranges of motion and functional scores, showed no statistically significant difference between groups. Conclusion The size of the bone loss per se does not seem to affect functional outcomes and complications from these procedures, which are safe techniques for small and large bone losses.


Resumo Objetivo Avaliar a relação do tamanho do defeito ósseo da glenoide no arco de movimento, nos resultados funcionais e nas complicações em pacientes atletas de alta performance submetidos a cirurgia de bloqueio ósseo para instabilidade anterior do ombro. Método Estudo retrospectivo no qual foram avaliados os resultados pós-operatórios de atletas submetidos a cirurgia de bloqueio ósseo para instabilidade anterior do ombro. Em 5 anos foram 41 ombros operados, sendo 20 deles com até 15% de defeito ósseo e 21 com defeitos entre 15% e 25%. Resultados Não houve diferença estatisticamente significativa com relação a complicações pós-operatórias, novas luxações, e na taxa de retorno ao esporte. Os critérios quantitativos avaliados - arcos de movimento e escores funcionais - também não apresentaram diferença estatisticamente significativa entre os grupos. Conclusão O tamanho do defeito ósseo por si só não parece afetar os resultados funcionais e as complicações desses procedimentos, sendo uma técnica segura tanto para defeitos pequenos, quanto para os maiores.

ABSTRACT

OBJECTIVE@#To evaluate the clinical outcomes of reverse total shoulder arthroplasty as a revision procedure for the failed fixation of proximal humeral fractures in the elderly patients.@*METHODS@#A retrospective analysis was performed on 8 patients with failed internal fixation of proximal humeral fractures from May 2014 to March 2020, including 3 males and 5 females, aged from 65 to 75 years old. All 8 patients underwent reverse total shoulder arthroplasty, and the mean time between initial fixation and reverse total shoulder arthroplasty ranged from 8 to 16 months. Range of motion(ROM), University of California at Los Angeles(UCLA) shoulder score, visual analogue scale (VAS), self-rating anxiety scale(SAS), and Constant-Murley score of shoulder function were assessed pre-operatively and at the last follow-up. Complications relating to the surgery were recorded.@*RESULTS@#All 8 patients successfully followed up. The mean follow-up after reverse total shoulder arhroplasty ranged from 16 to 28 months. The range of motion (forward flexion, external rotation, abduction and internal rotation) of the affected shoulder was significantly improved after surgery, and the post-operative VAS, SAS and UCLA scores were also significantly improved. For the Constant-Murley score of shoulder joint function, the total scores and the subscores of pain, daily activities, range of motion and strength test at the last follow-up were all significantly improved. Scapular glenoid notch was observed in patient, which was evaluated as grade 1 on imaging. All the other patients did not develop specific or non-specific complications.@*CONCLUSION@#Reverse total shoulder arhroplasty is an appropriate treatment as a revision surgery for failed fixation of proximal humeral fractures. It has shown satisfactory clinical outcomes, accelerating the rehabilitation of shoulder function and improving the quality of life.

ABSTRACT

OBJECTIVE@#To explore the clinical outcomes of anteromedial combined with lateral locking plate for complex proximal humeral fractures in the eldery.@*METHODS@#From June 2018 to October 2020, 30 patients who underwent surgical treatment for Neer grade 3 to 4 proximal humeral fractures, including 8 males and 22 females, aged from 51 to 78 years old with an average of (61.5±7.5) years old. Of them, 15 patients had fractures fixed with anteromedial combined with lateral locking plate(ALLP group), whereas 15 received internal fixation with proximal humerus locking plate only(PHLP group). The clinical data, simple shoulder test (SST), humeral head height loss, varus angle and shoulder range of motion were compared between the two groups.@*RESULTS@#All fractures were healed. The follow-up time ranged from 12 to 24 months, with an average of(14.3±2.9) months. The operation time of ALLP group was longer than that of PHLP group (P<0.05). There was no significant difference in intraoperative blood loss between the two groups (P>0.05). There was no significant difference in SST score between the two groups at 1, 3 and 12 months after operation (P>0.05). In terms of radiographic measurement, there was no significant difference in humeral head height loss and varus angle between the two groups at 1 and 3 months after operation (P>0.05). At 12 months after operation, the height loss and varus angle of humeral head in ALLP group were lower than those in PHLP group (P<0.05). In shoulder range of motion, the range of forward elevation in ALLP group was larger than that in PHLP group 1 year after operation(P<0.05). There was no significant difference in external rotation between the two groups.@*CONCLUSION@#Anteromedial combined with lateral locking plate in the treatment of complex proximal humeral fractures in the elderly can increase the stability of the medial column and obtain a good fracture prognosis. But there are also disadvantages such as longer operation time, so it should be individualized according to the fracture type of the patient.

ABSTRACT

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.

ABSTRACT

OBJECTIVE@#To investigate the synergistic interaction between the deltoid muscle and the rotator cuff muscle group in patients with rotator cuff tears (RCT), as well as the impact of the critical shoulder angle (CSA) on deltoid muscle strength.@*METHODS@#A retrospective analysis was conducted on clinical data from 42 RCT patients who met the selection criteria and were treated between March 2022 and March 2023. There were 13 males and 29 females, with an age range of 42-77 years (mean, 60.5 years). Preoperative visual analogue scale (VAS) score was 6.0±1.6. CSA measurements were obtained from standard anteroposterior X-ray films before operation, and patients were divided into two groups based on CSA measurements: CSA>35° group (group A) and CSA≤35° group (group B). Handheld dynamometry was used to measure the muscle strength of various muscle group in the shoulder (including the supraspinatus, infraspinatus, subscapularis, and anterior, middle, and posterior bundles of the deltoid). The muscle strength of the unaffected side was compared to the affected side, and muscle imbalance indices were calculated. Muscle imbalance indices between male and female patients, dominant and non-dominant sides, and groups A and B were compared. Pearson correlation analysis was used to examine the relationship between muscle imbalance indices and CSA as well as VAS scores.@*RESULTS@#Muscle strength in all muscle groups on the affected side was significantly lower than on the unaffected side ( P<0.05). The muscle imbalance indices for the supraspinatus, subscapularis, infraspinatus, and anterior, middle, and posterior bundles of the deltoid were 14.8%±24.4%, 5.9%±9.7%, 7.2% (0, 9.1%), 17.2% (5.9%, 26.9%), 8.3%±21.3%, and 10.2% (2.8%, 15.4%), respectively. The muscle imbalance indices of the anterior bundle of the deltoid, supraspinatus, and infraspinatus were significantly lower in male patients compared to female patients ( P<0.05); however, there was no significant difference in muscle imbalance indices among other muscle groups between male and female patients or between the dominant and non-dominant sides ( P>0.05). There was a positive correlation between the muscle imbalance indices of infraspinatus and VAS score ( P<0.05), and a positive correlation between CSA and the muscle imbalance indices of middle bundle of deltoid ( P<0.05). There was no correlation between the muscle imbalance indices of other muscle groups and VAS score or CSA ( P>0.05). Preoperative CSA ranged from 17.6° to 39.4°, with a mean of 31.1°. There were 9 cases in group A and 33 cases in group B. The muscle imbalance indices of the anterior bundle of the deltoid was significantly lower in group A compared to group B ( P<0.05), while there was no significant difference in muscle imbalance indices among other muscle groups between group A and group B ( P>0.05).@*CONCLUSION@#Patients with RCT have a phenomenon of deltoid muscle strength reduction, which is more pronounced in the population with a larger CSA.

ABSTRACT

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.

ABSTRACT

OBJECTIVE@#To testify the spatial relationship between the subscapularis muscle splitting window and the axillary nerve in modified arthroscopic Latarjet procedure, which could provide anatomical basis for the modification of the subscapularis muscle splitting.@*METHODS@#A total of 29 adult cadaveric shoulder specimens were dissected layer by layer, and the axillary nerve was finally confirmed to walk on the front surface of the subscapularis muscle. Keeping the shoulder joint in a neutral position, the Kirschner wire was passed through the subscapularis muscle from back to front at the 4 : 00 position of the right glenoid circle (7 : 00 position of the left glenoid circle), and the anterior exit point (point A, the point of splitting subscapularis muscle during Latarjet procedure) was recorded. The vertical and horizontal distances between point A and the axillary nerve were measured respectively.@*RESULTS@#In the neutral position of the shoulder joint, the distance between the point A and the axillary nerve was 27.37 (19.80, 34.55) mm in the horizontal plane and 16.67 (12.85, 20.35) mm in the vertical plane.@*CONCLUSION@#In the neutral position of the shoulder joint, the possibility of axillary nerve injury will be relatively reduced when radiofrequency is taken from the 4 : 00 position of the right glenoid (7 : 00 position of the left glenoid circle), passing through the subscapularis muscle posteriorly and anteriorly and splitting outward.

ABSTRACT

The shoulder joint is the most prone to dislocation in the whole body, and more than 95% of them are anterior dislocation. Improper treatment after the initial dislocation is easy to lead to recurrent anterior dislocation or anterior shoulder instability, and the outcomes following conservative treatment is poor. Anterior shoulder instability can damage the soft tissue structure and bone structure that maintain the stability of shoulder joint, among which bone structure is the most important factor affecting the stability of shoulder joint. Diagnosis should be combined with medical history, physical examination, and auxiliary examination. Currently, three-dimensional CT is the most commonly used auxiliary examination means. However, various bone defect measurement and preoperative evaluation methods based on three-dimensional CT and the glenoid track theory have their own advantages and disadvantages, and there is still a lack of gold standard. Currently, the mainstream treatment methods mainly include Bankart procedure, coracoid process transposition, glenoid reconstruction with free bone graft, Bankart combined with Remplissage procedure, and subscapular tendon binding tamponade, etc. Each of these procedures has its own advantages and disadvantages. For the diagnosis and treatment of anterior shoulder instability, there are still too many unknown, further research and exploration need to be studied.

ABSTRACT

Introducción: El objetivo de este estudio fue comparar la eficacia de los bloqueos interescalénico y supraescapular, solos y combinados, como analgesia posoperatoria en las primeras 3 horas tras la reparación artroscópica del manguito rotador. Materiales y métodos: Estudio de cohorte comparativo retrospectivo, realizado entre 2019 y 2021. El criterio de valoración principal fue el puntaje del dolor de hombro en la sala de recuperación evaluado con una escala analógica visual por el paciente. Los criterios de valoración secundarios fueron el consumo de opioides en la sala de recuperación y las complicaciones de la anestesia locorregional. Resultados: Se incluyó a 175 pacientes, 13 en el grupo de bloqueo interescalénico, 61 en el grupo de bloqueos interescalénico más supraescapular y 101 en el grupo de bloqueo supraescapular. Los grupos de bloqueo interescalénico y de bloqueo interescalénico más supraescapular tuvieron significativamente menos dolor en la sala de recuperación y una tasa total menor de opioides consumidos en miligramos equivalentes de morfina que el grupo de bloqueo supraescapular (p = 0,001 y p <0,01, respectivamente). No hubo diferencias significativas en el dolor ni el consumo de opioides entre el bloqueo interescalénico solo o combinado con bloqueo supraescapular. Conclusiones: El bloqueo interescalénico fue más eficaz que el bloqueo supraescapular para aliviar el dolor y disminuir el consumo de opioides en la sala de recuperación tras la reparación artroscópica del manguito rotador. La combinación de bloqueo interescalénico más bloqueo supraescapular no resultó en un incremento de la eficacia, y se sugiere no combinar estas dos técnicas. Nivel de evidencia: III


Introduction: This study aimed to compare the efficacy of interscalene block (ISB) and suprascapular nerve block (SSNB), individually and in combination (ISB+SSNB), used as postoperative analgesia within the first 3 hours after arthroscopic rotator cuff repair. Materials and methods: Retrospective comparative cohort study, conducted between 2019 and 2021. The primary endpoint was shoulder pain score in the immediate postoperative period as reported on a visual analog scale (VAS) by the patient. Secondary endpoints were opioid use in the recovery room (first 3 hours) and locoregional anesthesia complications. Results:175 patients were included; 13 in the ISB group, 61 in the ISB+SSNB group, and 101 in the SSNB group. The ISB group and the ISB+SSNB group had significantly less pain in the recovery room than the SSNB group (p = 0.001 and p < 0.001, respectively). The percentage of patients who required at least one dose of opioid and the total number of opioids consumed in milligrams of morphine equivalent were significantly lower for the ISB and ISB+SSNB groups than for the SSNB group (p < 0.001). There were no significant differences in pain or opioid use between ISB alone or combined with SSNB (ISB+SSNB). Conclusions: In this retrospective comparative study, ISB was more effective in relieving pain and reducing opioid use in the recovery room after ar-throscopic rotator cuff repair than SSNB. The ISB+SSNB combination did not increase effectiveness, and therefore it is suggested not to combine these two techniques. .Level of Evidence: III

ABSTRACT

Introducción: La capsulitis adhesiva es una enfermedad que se caracteriza por el engrosamiento de la cápsula articular del hombro, lo que se traduce clínicamente en dolor y una pérdida progresiva de la movilidad. El tratamiento conservador es la primera opción. En este estudio, se evaluó el uso de corticoesteroides articulares para el manejo de este cuadro. Materiales y Métodos: Se llevó a cabo un estudio retrospectivo entre 2015 y 2020. Se evaluaron los registros de consulta externa de pacientes con diagnóstico de capsulitis adhesiva u hombro congelado, que recibieron tratamiento con corticoesteroides por vía oral o articular. Resultados: Se analizó a 19 pacientes, 8 recibieron tratamiento por vía oral y 11, por vía articular. Hubo una mejoría importante en ambos grupos, pero los pacientes que recibieron corticoesteroides articulares comunicaron una mejoría a largo plazo. Conclusiones: La administración de corticoesteroides tanto por vía oral como articular para tratar la capsulitis adhesiva fue eficaz; sin embargo, a largo plazo, los corticoesteroides articulares resultaron más eficaces. Nivel de Evidencia: III


Introduction: Adhesive capsulitis is a condition defined by thickening of the shoulder joint capsule, which clinically translates into discomfort and progressive loss of range of motion, with conservative therapy being the initial option. In this study, we evaluate the use of intra-articular corticosteroid injections for the treatment of this condition. Materials and Methods: A retrospective analysis was conducted between 2015 and 2020, assessing the outpatient records of patients diagnosed with adhesive capsulitis or frozen shoulder and treated with corticosteroids either orally or intra-articularly. Results: A total of 19 patients were analyzed, 8 received oral treatment and 11 received intra-articular injection, with both groups showing considerable improvement, with the difference that the patients in the articular corticosteroid group reported long-term improvement. Conclusion: Corticosteroids have been found to be effective in the treatment of adhesive capsulitis both orally and by intra-articular injection; however, intra-articular corticosteroids have proved to be more effective in the long term.

ABSTRACT

Introducción: Las fracturas de clavícula representan el 4% de las fracturas del adulto; el 80% son mediodiafisarias. Se ha de-mostrado que el tratamiento quirúrgico disminuye el riesgo de seudoartrosis, consolidación viciosa y dolor residual, aunque no está exento de complicaciones, como la hipoestesia regional (12-29%), entre otras. Objetivo: Evaluar la incidencia de hipoestesia subclavicular luego de una reducción abierta y fijación interna para una fractura de clavícula, si afecta la calidad de vida del paciente y cómo la afecta. Materiales y Métodos: Se realizó un estudio transversal analítico prospectivo de pacientes con una fractura mediodiafisaria desplazada de clavícula tratados con reducción abierta y fijación interna entre 2018 y 2021. Se utilizó un cuestionario elaborado por el equipo, que consistió en 6 preguntas para responder de forma anónima. Se evaluó la presencia de hipoestesia subclavicular, dolor regional y afectación de la vida cotidiana. Resultados: Se evaluó a 29 pacientes con un seguimiento posoperatorio mínimo de un año, operados mediante un abordaje longitudinal. Veintidós (76%) tenían alteración de la sensibilidad y siete (24%) negaron este síntoma. La hipoestesia subclavicular afectó la calidad de vida de manera leve o nula del 97% de los pacientes. Conclusión: Es importante advertirle al paciente antes de la cirugía sobre la posibilidad de hipoestesia cutánea como complicación posoperatoria, debido a su alta frecuencia, aunque es poco probable que dicha complicación afecte la calidad de vida. Nivel de Evidencia: IV


Introduction: Clavicle fractures account for 4% of adult fractures, with mid-shaft fractures accounting for 80%. Although surgical treatment reduces the risk of pseudarthrosis, malunion, and residual pain, it is not without complications such as regional hypoesthesia (12-29%). Objective: To determine the prevalence of subclavicular hypoesthesia following open reduction and internal fixation for clavicle fracture, as well as if and how it impacts the patient's quality of life. Materials and Methods: A prospective cross-sectional analytical study of patients with displaced clavicle midshaft fractures treated with ORIF between 2018-2021 was performed. The research team used a questionnaire with six items that were completed anonymously. The presence of infraclavicular hypoesthesia, regional pain, and daily life interference was assessed. Results: Twenty-nine patients treated surgically with a longitudinal approach and with a minimum postoperative follow-up of one year were evaluated. Twenty-two patients (76%) had altered sensitivity, whereas seven (24%) denied the existence of the symptom. In 97% of individuals with subclavicular hypoesthesia, quality of life was impaired minimally or not at all. Conclusions: Before undergoing surgery, it is important to inform the patient about the risk of cutaneous numbness as a postoperative consequence due to its high frequency but improbable impact on daily activities.

ABSTRACT

La neuropatía del nervio supraescapular es una causa poco común de dolor y debilidad en el hombro y, por lo tanto, a menudo, es mal diagnosticada. Como consecuencia, el diagnóstico erróneo puede llevar a indicar un tratamiento conservador inapropiado o un procedimiento quirúrgico fallido. Se presenta el caso de un hombre de 55 años con síndrome de atrapamiento del nervio supraescapular. El paciente fue sometido a una artroscopia de hombro y se le diagnosticó una compresión del nervio supraescapular por el ligamento transverso escapular superior. La liberación artroscópica del nervio supraescapular alivió el dolor, la debilidad y la atrofia de los músculos supraespinoso e infraespinoso. Nivel de Evidencia: IV


Suprascapular neuropathy is a rare cause of shoulder pain and weakness and is therefore often misdiagnosed. As a consequence, misdiagnosis may lead to inappropriate conservative treatment or a failed surgical procedure. A case of a 55-year-old man suffering from suprascapular nerve entrapment syndrome is presented. The patient underwent shoulder arthroscopy, where the compression of the suprascapular nerve by the superior transverse scapular ligament was diagnosed. Arthroscopic release of the suprascapular nerve relieved pain, weakness, and atrophy of the supraspinatus and infraspinatus muscles. Level of Evidence: IV
