OBJECTIVE@#To explore the feasibility and effectiveness of a foldable pedicled latissimus dorsi myocutaneous flap to repair soft tissue defects in the shoulder and back.@*METHODS@#Between August 2018 and January 2023, the foldable pedicled latissimus dorsi myocutaneous flaps were used to repair soft tissue defects in the shoulder and back of 8 patients. There were 5 males and 3 females with the age ranged from 21 to 56 years (mean, 35.4 years). Wounds were located in the shoulder in 2 cases and in the shoulder and back in 6 cases. The causes of injury were chronic infection of skin and bone exposure in 2 cases, secondary wound after extensive resection of skin and soft tissue tumor in 4 cases, and wound formation caused by traffic accident in 2 cases. Skin defect areas ranged from 14 cm×13 cm to 20 cm×16 cm. The disease duration ranged from 12 days to 1 year (median, 6.6 months). A pedicled latissimus dorsi myocutaneous flap was designed and harvested. The flap was divided into A/B flap and then were folded to repair the wound, with the donor area of the flap being pulled and sutured in one stage.@*RESULTS@#All 7 flaps survived, with primary wound healing. One patient suffered from distal flap necrosis and delayed healing was achieved after dressing change. The incisions of all donor sites healed by first intention. All patients were followed up 6 months to 4 years (mean, 24.7 months). The skin flap has a good appearance with no swelling in the pedicle. At last follow-up, 6 patients had no significant difference in bilateral shoulder joint motion, and 2 patients had a slight decrease in abduction range of motion compared with the healthy side. The patients' daily life were not affected, and linear scar was left in the donor site.@*CONCLUSION@#The foldable pedicled latissimus dorsi myocutaneous flap is an ideal method to repair the soft tissue defect of shoulder and back with simple operation, less damage to the donor site, and quick recovery after operation.

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 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 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 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.

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 investigate the factors that influence the functional results of patients submitted to the Latarjet procedure. Methods Evaluation of 26 patients submitted to surgical treatment following the Latarjet technique due to traumatic recurrent anterior dislocation of the glenohumeral joint, with glenoidal bone loss greater than 20% and/or off-track injury. The minimum follow-up time was of 12 months. The Visual Analogue Scale (VAS), The Western Ontario Shoulder Instability Index (WOSI), and the Subjective Shoulder Value (SSV) scales, as well as objective data from the participants, were evaluated. Results Most patients (84.62%) did not present recurrence of the dislocation, and 92.31% were satisfied. Regarding the functional analysis, the physical component score (PCS) and the mental component score (MCS) found were within the mean quality of life of the population. The physical symptoms, according to the WOSI, presented the best percentage (8.5%), while the worst result was observed regarding lifestyle (20%). On the VAS, pain was classified as moderate (3/10) by 15.38% of the patients (4/26). In relation to sports, patients who practice sports showed improvement in SSV parameters, which had an inverse relationship with the number of relapses. It was also observed that the shorter the time between the first dislocation and the surgery, the greater the patient's satisfaction. Conclusion Early indication of surgical treatment of anterior glenohumeral instability may provide better subjective functional results to the patient.

Resumo Objetivo Investigar os fatores que influenciam os resultados funcionais dos pacientes submetidos ao procedimento de Latarjet. Métodos Avaliação de 26 pacientes submetidos ao tratamento cirúrgico, seguindo a técnica de Latarjet, devido a luxação anterior recidivante traumática da articulação glenoumeral, com perda óssea glenoidal maior do que 20% e/ou lesão off-track. O tempo mínimo de seguimento foi de doze meses. Foram avaliadas as seguintes escalas: Escala Visual Analógica (EVA), The Western Ontario Shoulder Instability Index (WOSI), e Subjective Shoulder Value (SSV), além dos dados objetivos dos participantes. Resultados A maioria dos pacientes (84,62%) não apresentou recidiva de luxação, e 92,31% ficaram satisfeitos. Em relação à análise funcional, a pontuação do componente físico (PCF) e a pontuação do compenente mental (PCM) encontradas estavam dentro da média de qualidade de vida da população. Os sintomas físicos, pela escala WOSI, apresentaram a melhor porcentagem (8,5%), ao passo que o pior resultado foi observado com relação ao estilo de vida (20%). Na EVA, a dor foi classificada como moderada (3/10) por 15,38% dos pacientes (4/26). Em relação aos esportes, os pacientes que praticavam alguma atividade esportiva apresentaram melhora nos parâmetros da escala SSV, que tiveram relação inversa com o número de recidivas. Observou-se ainda que, quanto menor foi o tempo entre a primeira luxação e a realização da cirurgia, maior foi a satisfação do paciente. Conclusão A indicação precoce do tratamento cirúrgico da instabilidade anterior glenoumeral pode proporcionar melhores resultados funcionais subjetivos ao paciente.

Abstract Interscalene brachial plexus (ISB) block is considered the analgesic technique of choice for shoulder surgery. However, the hemidiaphragmatic paresis that may occur after the block has led to the search for an alternative to the ISB block. In this case report, the pericapsular nerve group (PENG) block was performed for both surgical anesthesia and postoperative analgesia in two patients who underwent shoulder surgery. It is suggested that the PENG block can be safely applied for analgesia and can be part of surgical anesthesia, but alone is not sufficient for anesthesia. The block of this area did not cause motor block or pulmonary complications, nor result in muscle laxity, blocking only the shoulder and the upper third of the humerus. It was demonstrated that the PENG block may be safely applied for both partial anesthesia and analgesia in selected shoulder surgery cases.

A estabilidade da articulação do ombro é garantida por ligamentos, cápsula articular, tendões e músculos, contudo traumas podem causar falência dos mecanismos estabilizadores, com consequente luxação ou instabilidade articular. Objetivou-se relatar o caso de instabilidade medial e lateral de ombro direito em felino sem raça definida, atendido com queixa de claudicação aguda de membro torácico secundária a trauma por confronto com outro animal. Inicialmente foi realizado tratamento clínico por meio de imobilização articular. Contudo, devido ao insucesso da técnica, procedeu-se para o tratamento cirúrgico de estabilização articular com prótese ligamentar sintética. No pós-operatório imediato, evidenciou-se ausência de crepitações e instabilidade articular. Após oito dias da cirurgia, o paciente apresentou retorno total às funções de apoio do membro e sem sinais de dor ou redução de movimentos. Concluiu-se que, embora de reduzida ocorrência, a instabilidade de origem traumática do ombro configura-se como um diferencial para claudicação aguda de membro torácico e que o tratamento cirúrgico pode ser necessário, mostrando-se eficiente na resolução de tais casos com o acesso e técnica de estabilização propostos.

The stability of the shoulder joint is granted by ligaments, joint capsule, tendons and muscles. However, traumatic injuries can cause failure of the stabilization mechanisms, which leads to articular luxation or instability. The aim of the paper is to report a case of medial and lateral right shoulder joint instability in a mixed-breed cat, presenting acute forelimb lameness after a fight trauma with another cat. Initially, it was recommended a conservative treatment through articular immobilization. However, the technique was unsuccessful, and the surgery treatment was performed, to stabilize the joint with synthetic ligament prosthetic. In the postoperative period, no crepitation or instability were identified. After eight days of surgery, the patient returned totally to the normal function of the forelimb, without movement restriction or pain. It was concluded that, although rare, the traumatic shoulder joint instability is a differential diagnosis for acute forelimb lameness and the surgical treatment can be necessary, showing a good result in the resolution of these injuries with the surgical approach and stabilization method proposed.

Abstract The indication of shoulder arthroplasties has increased progressively. Accurate positioning of the components may have significant implications for clinical results. The navigation used to aid in the performance of anatomical and reverse total arthroplasties has provided greater precision in implant placement, especially on the glenoid. The development of the technique, material, and prosthesis design have shown encouraging results and led to a trend toward its expansion. In this way, we estimate a higher survival of the arthroplasties resulting from lower rates of dislocation and early loosening. We aim to describe the current technique and to present the results of the literature with navigation. However, comparative clinical studies with long term follow-up are necessary to prove the efficacy in the final results of total shoulder arthroplasties.

Resumo A indicação de artroplastias do ombro aumentou progressivamente. O posicionamento preciso dos componentes pode ter implicações significativas para os resultados clínicos. A navegação utilizada para auxiliar no desempenho de artroplastias totais anatômicas e reversas tem proporcionado maior precisão na colocação do implante, especialmente do componente glenoidal. O desenvolvimento da técnica, do material e do desenho da prótese têm mostrado resultados encorajadores e levado a uma tendência de expansão da sua utilização. Dessa forma, estimamos uma maior sobrevida das artroplastias resultantes de menores taxas de instabilidade e soltura precoce. Nosso objetivo é descrever a técnica atual e apresentar os resultados da literatura com navegação. No entanto, estudos clínicos comparativos com acompanhamento de longo prazo são necessários para comprovar a eficácia nos resultados finais das artroplastias totais do ombro.

Abstract Objective The present study aimed to identify bacterial agents in shoulder surgery specimens from patients with no history of previous shoulder infection or surgery. Methods Tendon, bursa, and bone specimens were collected during surgery, stored in sterile dry bottles, and sent to a hospital-associated laboratory for culture growth analysis in media for aerobic and anaerobic agents. Findings from 141 samples from 47 shoulders were analyzed. Results The cultures were negative in 46 cases (97.8%) and in 140 samples (99.2%). The culture was positive in a single patient, with growth of Staphylococcus hominis from one of three specimens collected. Conclusions The rates of bacterial growth were not consistent with the international literature, indicating the low effectiveness of laboratory methods used in Brazil.

Resumo Objetivo Identificar agentes bacterianos em amostras de cirurgias do ombro de pacientes sem histórico de infecção e de cirurgias prévias no ombro. Métodos Amostras de tendão, bursa e osso foram coletadas no intraoperatório, armazenadas em frascos estéreis a seco e enviadas para análise de crescimento de cultura em meios para agentes aeróbios e anaeróbios no laboratório credenciado ao hospital. Foram analisados os resultados de 141 amostras de 47 ombros. Resultados Obtivemos resultados de culturas negativas em 46 casos (97,8%) e em 140 amostras (99,2%). Apenas um paciente apresentou resultado positivo, com crescimento bacteriano do Staphylococcus hominis em uma das três amostras coletadas. Conclusões Não evidenciamos taxas de crescimento bacteriano condizentes com a literatura internacional, alertando para a baixa eficácia dos métodos laboratoriais utilizados no nosso país.

Abstract The present study created a cheap (below US$ 100) shoulder arthroscopy training model, affordable for the practical education of medical students and residents. The model was created using a polyvinyl chloride (PVC) knee joint pipe (150 mm in diameter and 90 degrees in inclination) and a synthetic shoulder model. The parts were arranged to simulate a lateral recumbency with the upper limb in traction, which is the frequent positioning during arthroscopies. Colored dots on the glenoid and a partial rotator cuff model on the upper portion of the scapula were placed to assist training. This inexpensive, easy-to-make model for shoulder arthroscopy can aid surgical training.

Resumo O objetivo do presente trabalho é criar um modelo de treinamento em artroscopia de ombro de baixo custo abaixo de 100 dólares, tornando-o acessível à capacitação prática de estudantes de medicina e residentes. O modelo foi criado utilizando um cano de PVC de 150 mm de diâmetro em 90 graus e um modelo de ombro sintético. O posicionamento das peças foi disposto de forma a simular a posição de decúbito lateral com membro superior em tração, frequente nas artroscopias. Para auxiliar no treinamento, foram demarcados pontos coloridos na glenóide e foi confeccionado um modelo de parte do manguito rotador na porção superior da escápula. Foi possível confeccionar um modelo para treinamento de artroscopia do ombro com um valor abaixo de 100 dólares, de fácil manufatura, que pode ser um auxiliar no treinamento de cirurgiões.

INTRODUCTION@#Shortening of the tendon and muscle is recognised as a strong predictor of surgical failure of supraspinatus tendon tears. Changes in muscle architecture following repair have not been thoroughly investigated. Hence, we aimed to compare the pre- and postoperative architecture of the supraspinatus.@*METHODS@#We recruited eight participants with full-thickness supraspinatus tears. Images of the supraspinatus were captured preoperatively (pre-op) and postoperatively at one month (post-op1), three months (post-op2) and six months (post-op3) in relaxed and contracted states (0º and 60º glenohumeral abduction). Fibre bundle length (FBL), pennation angle (PA) and muscle thickness were quantified. Self-reported function, and maximal isometric abduction and external rotation strengths were assessed.@*RESULTS@#The mean FBL increased from pre-op to post-op1 (p = 0.001) in the relaxed state and from pre-op to post-op2 (p = 0.002) in the contracted state. Decrease in FBL was observed from post-op2 to post-op3 in the relaxed state. The mean PA decreased from pre-op to post-op1 (p < 0.001) in the relaxed state, but increased from post-op2 to post-op3 in both relaxed (p = 0.006) and contracted (p = 0.004) states. At post-op3, external rotation (p = 0.009) and abduction (p = 0.005) strengths were greater than at post-op2. Overall function increased by 47.67% from pre-op to post-op3.@*CONCLUSION@#Lengthening of the supraspinatus occurs with surgery, altering the length-tension relationship of the muscle, which can compromise muscle function and lead to inferior surgical outcomes. These findings may guide clinicians to optimise loads, velocities and shoulder ranges for effective postoperative rehabilitation.

OBJECTIVE@#To compare the effect of two different arthroscopic procedures, threading lasso fixation and full-thickness conversion, for repairing articular-sided partial-thickness supraspinatus tendon tear.@*METHODS@#From July 2015 to November 2018, 21 patients with articular-sided partial-thickness supraspinatus tendon tears underwent arthroscopic modified threading lasso fixation repair(group A). There were 12 males and 9 females in the group, with an average age of(53.2±6.4)years old. Twenty-four patients with articular-sided partial-thickness supraspinatus tendon tears received arthroscopic full-thickness conversion repair(group B). In this group, there were 14 males and 10 females, with an average age of (55.7±5.2) years old. The American Shoulder and Elbow Surgeons (ASES) score and University of California Los Angeles (UCLA) shoulder score were used to evaluate preoperative and postoperative clinical function. MRI was used to examine the healing status of the reconstructed rotator cuff.@*RESULTS@#All patients were followed up, and the duration ranged from 20 to 27 months, with a mean of (23.7±3.1) months. In threading lasso fixation group, ASES score and UCLA score increased from 50.6±6.4 and 15.6±2.7 preoperatively to 87.3±5.2 and 31.6±2.4 postoperatively. In full-thickness conversion group, ASES score and UCLA score increased from 52.3±5.6 and 16.8±2.4 scores to 90.1±4.8 and 32.1±2.8. There were also no significant differences in ASES score and Constant score between the two groups before and after operation. There were no significant differences in rotator cuff healing between the two groups(χ2=2.374, P=0.128).@*CONCLUSION@#For the treatment of articular-sided partial-thickness supraspinatus tendon tears both arthroscopic repairs employing threading lasso fixation and full-thickness conversion could achieve satisfactory clinical results, and there are no significant differences in clinical outcomes between the two techniques. Arthroscopic repair with threading lasso fixation is a novel transtendinous procedure in which integrity of the tendon can be preserved.

Objective: To evaluate the shoulder function in patients after repair of head and neck defects with supraclavicular flap. Methods: A retrospective analysis was performed on 56 patients (54 males, 2 females, aged 35-74 years old) who received the repair of head and neck defects with supraclavicular flaps at Department of Otorhinolaryngology Head and Neck Surgery of Beijing Tongren Hospital, Capital Medical University in January 2013-December 2020. The areas and types of flaps, disruption or infections of the incision at the donor sites and other postoperative complications were recorded. Quick disabilities of the arm, shoulder and hand (Quick-DASH) was used for evaluating the shoulder functions in 43 patients conforming to the standard for evaluation of the clinical functions of shoulders and upper limbs, to compare the postoperative upper limb functions between patients treated with clavicular flaps and patients with acromion flaps. Meanwhile, 30 patients who received bilateral neck lymph node dissection over the same period of time were selected for a comparative evaluation of the donor sides (observation group) and the opposite sides (control group). Data were processed with SPSS 22.0. Results: The areas of obtained supraclavicular flaps were (4-10) cm × (10-18) cm. Three patients (5%) showed the defect widths of 8-10 cm at the donor sites, which couldn't be sutured directly, received the repair of their shoulder defects with partial flaps. Defects in other patients were sutured directly. After surgery, 3 patients (5%) suffered from disruption of the acromion incision, which healed after 2 weeks of local dressing. The follow-up time was 6-43 (27±14) months. All patients expressed no dissatisfaction with the appearance. Among 43 patients, 28 (65%) were clavicular type and 15 (35%) were acromion type. The acromion type showed average motor ability and Quick-DASH scores higher than the clavicular type [(average motor ability: (14.4±4.7) vs. (11.8±3.1), t=2.105, P=0.048; Quick-DASH: (16.9±11.6) vs. (12.2±7.1), t=2.284, P=0.033]. Among 30 patients who received bilateral neck lymph node dissection over the same period of time, the observation group showed higher average motor ability, local symptoms and Quick-DASH scores than the control group [average motor ability: (13.4±5.8) vs. (9.8±4.2), t=3.024, P=0.004; average local symptoms: (4.1±1.0) vs. (3.4±1.0), t=2.537, P=0.014; Quick-DASH: (15.6±14.7) vs. (5.2±11.1), t=3.106, P=0.003]. Conclusion: Shoulder dysfunction exists after treatment with supraclavicular flap, which is related to the flap type.

OBJECTIVE@#To investigate the method and clinical effects of the treatment of recurrent anterior dislocation of shoulder with Hill-Sachs injury by arthroscopic Bankart repair and Remplissage.@*METHODS@#From March 2016 to March 2019, 106 patients with recurrent anterior dislocation of shoulder with glenoid bone defect less than 20% underwent arthroscopic Bankart repair, including 76 males and 30 females, aged from 18 to 45 (27.3±8.6) years, 59 cases of left shoulder and 47 cases of right shoulder. Range of motion (ROM), American Shoulder and Elbow Surgeons(ASES) score, Constant-Murley score and Rowe score were used to evaluate shoulder functionand stability before and after operation.@*RESULTS@#All patients were followed up, and the duration ranged from 21 to 60 months, with a mean of (41.5± 8.5) months. One patient developed infection after operation, and the infection was controlled after arthroscopic debridement again. The remaining patients did not have clinical complications such as infection, intra articular hematocele and redislocation. Shoulder flexion and lifting increased from (158.33±15.72) ° preoperatively to (169.43±10.04) ° at the latest follow up, and internal rotation changed from T7 (T4 to T10) preoperatively to T8 (T5 to T10) at the latest follow up;the average lateral external rotation and abduction 90 ° external rotation decreased from (58.46±15.51) ° preoperatively and (99.37±14.09) ° to (53.18±14.90) ° and (92.52±13.10) ° at the latest follow up, respectively. The ASES score, Constant -Murley score and Rowe score were significantly improved.@*CONCLUSION@#The clinical effect of rehabilitation of Bankart repair combined with Remplissageunder arthroscopy in the treatment of recurrent dislocation of shoulder joint in adults with Hill-Sachs defect is satisfactory. Although the external rotation function is weaker than that before operation, it can effectively reconstruct the shoulder function and avoid the occurrence ofdislocation after operation.
