Detection of Cutibacterium acnes in Tissue Samples from Clean Primary Shoulder Surgeries - Part II.

Objective Research and identification of Cutibacterium acnes ( C. acnes ) and other microorganisms in deep tissue 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%).

Allograft-enhanced latissimus dorsi transfer is better than the conventional technique for irreparable posterosuperior rotator cuff tears. A retrospective matched cohort.

PURPOSE: Latissimus dorsi tendon (LDT) transfer (LDTT) to the greater tuberosity to treat irreparable posterosuperior rotator cuff tears (RCTs) in young active patients has been shown to have up to 36% of clinical failures, most of them happening because of either deltoid origin disruption or post-operative transfer rupture from the greater tuberosity. In an attempt to simultaneously prevent both complications, a modified technique includes the following adaptations to the original technique: reinforcement and augmentation of the LDT with a tendinous allograft, enabling the use of a single deltopectoral approach. The aim of this study is to compare mid-term outcomes of the traditional LDTT technique with this modified transfer. METHODS: Retrospective cohort study comparing two groups who underwent either the traditional (group 1; n = 19) or the modified technique (group 2; n = 27). Group homogenization was assured by statistical comparison of 24 baseline independent variables. The outcome variables were the gains to active shoulder range of motions (ROM) and UCLA scores (and all its subscores, independently), at a minimum follow-up of two years. A p value < .05 was considered to be statistically significant. RESULTS: At a mean follow-up of 25 months, both groups have shown improvements to most variables. However, group two (modified technique) achieved greater improvements to UCLA score (p = .009), active external rotation (p = .006) and internal rotation (p = .008). CONCLUSION: At mid-term follow-up, improvements to outcomes of the modified (single approach, allograft-enhanced) latissimus dorsi transfer were greater than those of the original technique.

EVALUATION OF SCAPULAR DYSKINESIS IN CROSSFIT®- PRACTICING ATHLETES.

Objective: Evaluate the scapular movement of Crossfit® practitioners and identify whether they present an increased incidence of scapular dyskinesis (SD) compared to non-practitioners. Method: A transversal study was evaluated quantitatively and dynamically, using retro-reflective spherical markers, the scapular movements of ten volunteers composing the control group, and 11 Crossfit® practitioners. The control group's results were used as a normality parameter and compared to those of the Crossfit® practitioner's group. Results: It was identified that the superior scapular rotation in the ascending phase is inferior in the group of Crossfit® practitioners (p = 0.02). Conclusion: The regular practice of Crossfit® causes scapular dyskinesis (SD), with alteration in the scapular superior rotation movement. Level of Evidence III: Retrospective comparative .

Objetivo: Avaliar o movimento escapular de praticantes de Crossfit® e identificar se apresentam incidência aumentada de discinese escapular (DE) quando comparados a não praticantes. Método: Estudo transversal que avaliou de forma quantitativa e dinâmica, utilizando marcadores retro-refletivos esféricos, os movimentos escapulares de dez voluntários, compondo o grupo controle, e 11 praticantes de Crossfit®. Os resultados do grupo controle foram utilizados como parâmetro de normalidade e comparados aos do grupo de praticantes de Crossfit®. Resultados: Identificou-se que a rotação superior escapular na fase ascendente é inferior no grupo de praticantes de Crossfit® (p = 0,02). Conclusão: A prática regular de Crossfit® causa discinese escapular (DE), com alteração no movimento de rotação superior da escápula. Nível de Evidência III: Retrospectivo comparativo .

EVALUATION OF SCAPULAR DYSKINESIA IN PATIENTS THAT UNDERWENT A LATARJET PROCEDURE.

Objective: To quantitatively assess the scapular movement of patients who underwent Latarjet surgery and to identify if they present scapular dyskinesia (SD), as well as correlate with the clinic state and the elevation degree of the shoulder. Methods: A cross-sectional study was carried out at the Movement Analysis Laboratory (LAM), at the Institute of Physical Activity and Sport Sciences, that quantitatively evaluated, using spherical retroreflective markers, the scapular movements of the control group (10 volunteers) and 22 patients (23 operated shoulders) that had been submitted to Latarjet surgery, between 2011 and 2016, with at least one year postoperative. The results of the control group were used as a parameter of normality and compared to those of the operated group. Posterior inclination, superior rotation, and medial rotation of the scapula were evaluated at angles of 60°, 90°, and 120° of elevation, both in ascending and descending phases. The statistical analysis used was the multivariate variance (MANOVA), comparing the right and left sides of the control group and, subsequently, the control group with the postoperative group (p = 0.05 in all tests). Results: When comparing the mean of the results of the quantitative evaluation of the control group with the operated group, no statistically significant differences were found between the two groups and between the dominant and non-dominant sides of the control group. Conclusion: Latarjet surgery does not cause SD, although there are alterations in some plane of the scapular movements in the ascending and/or descending phase. Level of Evidence III, Retrospective Comparative Study.

Objetivo: Avaliar, de forma quantitativa, o movimento escapular dos pacientes submetidos à cirurgia de Latarjet e identificar se apresentam discinesia escapular (DE). Além disso, correlacionar com a clínica e com o grau de elevação do ombro. Método: Estudo transversal realizado no Laboratório de Análise do Movimento (LAM), no Instituto de Ciências da Atividade Física e Esporte que avaliou de forma quantitativa, utilizando marcadores retro-refletivos esféricos, os movimentos escapulares do grupo controle (10 voluntários) e 22 pacientes (23 ombros operados), submetidos à cirurgia de Latarjet, entre os anos de 2011 e 2016, com pelo menos um ano de pós-operatório. Foram utilizados os resultados do grupo controle como parâmetro de normalidade e posteriormente comparados aos do grupo de pacientes operados. Avaliadas a inclinação posterior, rotação superior e rotação medial das escápulas nos ângulos de 60°, 90° e 120° de elevação, tanto na fase ascendente quanto na descendente. A análise estatística utilizada foi a multivariada da variância (MANOVA) comparando os lados direito e esquerdo do grupo controle e posteriormente o grupo controle com o grupo pós-operatório (p = 0,05 em todos os testes). Resultados: Ao compararmos a média dos resultados da avaliação quantitativa do grupo controle com o grupo dos operados, não foram evidenciadas diferenças estatisticamente significativas entre os dois grupos, assim como os lados dominante e o não dominante do grupo controle. Conclusão: A cirurgia de Latarjet não causa DE, apesar de haver alterações em algum plano dos movimentos escapulares na fase ascendente e/ou descendente. Nível de Evidência III, Estudo Retrospectivo Comparativo.

Humeral Head Osteonecrosis: Outcomes of Hemiarthroplasty After Minimum 10-Year Follow-Up.

Objective To analyze long-term functional and radiographic results of partial shoulder replacement for humeral head osteonecrosis. Methods Retrospective review of thirteen cases, with a mean postoperative follow-up of 17 years (range 10 to 26 years). The findings from the last follow-up were compared to those in which the patients had one year of postoperative follow-up. Functional assessment consisted of shoulder movement measurements and application of the University of California, Los Angeles (UCLA) shoulder score. All patients underwent radiographic examination to measure glenoid erosion, proximal humeral migration and lateral glenohumeral dislocation. Results Glenoid erosion increased over time significantly ( p < 0.05). Paradoxically, all active shoulder movements also improved ( p < 0.05), while UCLA scores remained the same. Radiographic deterioration was not correlated with clinical function. We had an 84.7% survival rate for arthroplasties after a mean time of 16 years. Conclusions Early functional outcomes were maintained in the long run and do not correlate with radiographic deterioration (increased erosion of the glenoid).

Latissimus Dorsi Tendon Transfer using Tendinous Allograft for Irreparable Rotator Cuff Lesions: Surgical Technique.

Latissimus dorsi transfer around the shoulder is the most frequently used surgical technique to treat young patients with irreparable posterosuperior rotator cuff lesions. This technique, as initially described and popularized by Gerber et al., has two main drawbacks that may predispose to complications and unsatisfactory functional results: 1) postoperative rupture of the origin of the deltoid, as its detachment from the acromion is necessary during the superior approach to the shoulder; and 2) postoperative rupture of the transferred tendon. In an attempt to avoid these problems, the authors have developed the following modifications to the original technique. Through a deltopectoral approach, the latissimus dorsi tendon is identified and detached from the humerus shaft. After being reinforced and elongated with a tendinous allograft, it is transferred around the humerus and fixed to the superolateral aspect of the greater tubercle. No rigid thoraco-brachial immobilization is used postoperatively.

Are the good functional results from arthroscopic repair of massive rotator cuff injuries maintained over the long term?

OBJECTIVE: To evaluate whether the good and excellent functional results from arthroscopic repair of massive rotator cuff tears are maintained over the long term. METHODS: From the sample of the study conducted by our group in 2006, in which we evaluated the functional results from arthroscopic repair of massive rotator cuff tears, 35 patients were reassessed, 8 years after the first evaluation. The inclusion criteria were that these patients with massive rotator cuff tears operated by means of an arthroscopic technique, who participated in the previous study and achieved good or excellent outcomes according to the UCLA criteria. Patients whose results were not good or excellent in the first evaluation according to the UCLA criteria were excluded. RESULTS: Among the 35 patients reassessed, 91% of them continued to present good and excellent results (40% excellent and 51% good), while 3% presented fair results and 6% poor results. The time interval between the first and second evaluations was 8 years and the minimum length of follow-up since the immediate postoperative period was 9 years (range: 9-17 years), with an average of 11.4 years. CONCLUSION: The good and excellent results from arthroscopic repair of massive rotator cuff tears were mostly maintained (91%), with the same level of function and satisfaction, even though 8 years had passed since the first assessment, with a follow-up period averaging 11.4 years.

MÉTODOS: A partir da amostra do trabalho feito por nosso grupo em 2006, no qual avaliamos os resultados funcionais do reparo artroscópico das lesões extensas do manguito rotador, foram reavaliados 35 pacientes, totalizando oito anos após a primeira avaliação. Critérios de inclusão: pacientes com lesão extensa do manguito rotador operados por técnica artroscópica que participaram do trabalho anterior e que obtiveram bons ou excelentes resultados segundo os critérios da UCLA. Critérios de exclusão: pacientes que não obtiveram resultado bom ou excelente segundo os critérios da UCLA na primeira avaliação. RESULTADOS: Dos 35 pacientes reavaliados, 91% mantiveram-se com bons e excelentes resultados (40% excelentes, 51% bons), 3% regulares e 6% ruins. O intervalo de tempo entre a primeira e a segunda avaliação foi de oito anos, o tempo de seguimento mínimo desde o pós-operatório imediato foi de nove anos, variou entre nove e 17 anos com média de 11,4. CONCLUSÃO: Os bons e excelentes resultados do reparo artroscópico das lesões extensas do manguito rotador mantiveram-se em sua maioria (91%) com o mesmo nível de função e satisfação mesmo após oito anos de sua primeira avaliação, totalizando tempo de seguimento com média de 11,4 anos.

Evaluation of the results from non-arthroplastic treatment (arthroscopy) for shoulder arthrosis.

OBJECTIVES: To evaluate the functional results from patients with arthrosis who underwent an arthroscopic procedure, in an attempt to correlate these results with the patients' epidemiological profile, surgical technique used, possible complications and postoperative protocol. METHODS: Between 1998 and 2011, 31 patients (32 shoulders) with shoulder arthrosis underwent arthroscopic treatment performed by the Shoulder and Elbow Group of the Department of Orthopedics and Traumatology of Santa Casa de São Paulo. Primary or secondary cases of shoulder arthrosis under the age of 70 years, in which the rotator cuff was intact, were included. Furthermore, cases in which, despite an indication for an arthroplastic procedure, an attempt to perform an alternative procedure had been chosen, were also included. The following were evaluated: sex, age, dominance, comorbidities, length of time with complaint, associated lesions, etiology, previous treatment, operation performed, postoperative protocol and pre and postoperative active ranges of motion. The functional evaluation was conducted using the UCLA criteria, before and after the operation. The joint cartilage alterations were classified in accordance with Outerbridge and the arthrosis by means of Walch. RESULTS: There were statistically significant mean differences in the values for elevation, lateral rotation and medial rotation from before to after the operation (p < 0.001) and there was a tendency (p = 0.057) toward poor results with greater length of time with complaints before the surgery. The total gain in UCLA score did not have any statistically significant relationship with any of the other variables analyzed. CONCLUSION: Arthroscopic treatment of glenohumeral arthrosis provided functional improvement of the glenohumeral joint, with significant gains in elevation and lateral and medial rotation, and improvements in function and pain. Greater length of time with complaints was a factor strongly suggestive of worse results.

OBJETIVOS: Avaliar os resultados funcionais obtidos dos pacientes com artrose submetidos ao procedimento artroscópico e tentar correlacioná-los com o perfil epidemiológico do doente, a técnica cirúrgica usada, as eventuais complicações e o protocolo pós-operatório. MÉTODOS: Entre 1998 e 2011, 31 pacientes (32 ombros) com artrose do ombro foram submetidos ao tratamento artroscópico pelo Grupo de Ombro e Cotovelo do Departamento de Ortopedia e Traumatologia da Santa Casa de São Paulo. Foram incluídos os casos de artrose de ombro primária ou secundária, abaixo dos 70 anos, com manguito rotador íntegro, e ainda aqueles que, apesar de indicado o procedimento artroplástico, decidiram tentar uma opção. Foram avaliados: sexo, idade, dominância, comorbidades, tempo de queixa, lesões associadas, etiologia, tratamento prévio, operação feita, protocolo pós-operatório e arco de movimento ativo, pré e pós-operatório. A avaliação funcional foi feita pelos critérios da UCLA pré e pós-operatoriamente. As alterações da cartilagem articular foram classificadas por Outerbridge e a artrose por Walch. RESULTADOS: Houve diferença média estatisticamente significativa entre os valores para elevação, rotação lateral e medial pré e pós-operatória (p < 0,001) e uma tendência (p = 0,057) de maus resultados com o maior tempo de queixa pré-cirúrgica. O ganho total da UCLA não tem relação estatisticamente significativa com todas as outras variáveis analisadas. CONCLUSÃO: O tratamento artroscópico da artrose glenoumeral propicia melhoria funcional da articulação glenoumeral, com ganhos significativos de elevação, rotação lateral e medial e melhoria da função e da dor, e o maior tempo de queixa é fator fortemente sugestivo para piores resultados.

Axillary artery lesion secondary to fracturing of the proximal third of the humerus: case report.

Lesions of the axillary artery are rare in patients with fracturing of the proximal third of the humerus and may have greatly varying clinical manifestations. They are responsible for 15% and 20% of upper-limb artery injuries and the commonest mechanism is a fall to the ground, which accounts for 79% of such injuries. In some cases, the signs only appear later on. It is important to bear this association in mind, so as to make an early diagnosis and avoid serious complications. We report on a case of traumatic injury of the axillary artery secondary to fracturing of the proximal third of the humerus in an 84-year-old patient, with late evolution of clinical signs of ischemia in the limb affected. The aim here was to discuss the diagnostic difficulties and treatment.

As lesões da artéria axilar são raras em pacientes com fraturas do terço proximal do úmero e podem ter manifestações clínicas bastante variadas. São responsáveis por 15% a 20% das lesões arteriais dos membros superiores e o mecanismo mais comum é a queda ao solo, que representa 79% dos traumas. Em alguns casos os sinais só aparecem tardiamente. É importante lembrar essa associação, a fim de diagnosticá-la precocemente e evitar complicações graves. Relatamos um caso de lesão traumática da artéria axilar secundária à fratura do terço proximal do úmero em uma paciente de 84 anos, com evolução tardia dos sinais clínicos de isquemia do membro acometido. O objetivo é discutir as dificuldades do diagnóstico e do tratamento.

Evaluation of the results from surgical treatment of fractures of the lateral extremity of the clavicle, using the double ligature technique.

OBJECTIVE: To evaluate the incidence of consolidation in surgical treatment of fractures of the lateral extremity of the clavicle using the double subcoracoid ligature technique, with nonabsorbable No. 5 thread. METHODS: Between May 1993 and June 2013, the Shoulder and Elbow Group of our service surgically treated 116 patients (116 shoulders) with fractures of the lateral extremity of the clavicle. Among these, we were able to reassess 65 cases. The surgical technique used consisted of double subcoracoid ligature with two nonabsorbable threads. In two patients classified as type III, we had to combine this technique with use of an interfragmentary screw for fixation of the intra-articular portion of the acromioclavicular joint. RESULTS: We achieved fracture consolidation in 90%. Fourteen cases (21%) evolved with major complications: four cases of pseudarthrosis, five of adhesive capsulitis, two of delayed consolidation and three of loss of reduction. Two cases (3%) evolved with minor complications of skin granuloma. CONCLUSION: The double ligature technique for fractures of the lateral extremity of the clavicle promotes the stabilization needed for consolidation to take place, without the need for synthesis using metal components. It avoids reoperation for the synthesis material to be removed. Moreover, it is a low-cost procedure with good reproducibility and preservation of the acromioclavicular joint.

OBJETIVO: Avaliar a incidência de consolidação do tratamento cirúrgico nas fraturas da extremidade lateral da clavícula pela técnica do duplo amarrilho subcoracóideo com o uso de fio inabsorvível número 5. MÉTODOS: Entre maio de 1993 e junho de 2013, o Grupo de Ombro e Cotovelo do nosso serviço tratou cirurgicamente 116 pacientes (116 ombros) com fratura da extremidade lateral da clavícula. Desses, conseguimos reavaliar 65. A técnica cirúrgica usada foi o amarrilho duplo subcoracóideo com dois fios inabsorvíveis. Em dois pacientes classificados como tipo III tivemos de associar um parafuso interfragmentário para fixação da porção intra-articular da AC. RESULTADOS: Tivemos 90% de consolidação da fratura; 14 casos (21%) evoluíram com complicações maiores: quatro pseudoartroses, cinco capsulites adesivas, dois retardos de consolidação e três perdas de redução; e dois casos (3%) evoluíram com complicação menor: granuloma de pele. CONCLUSÃO: A técnica do amarrilho duplo para as fraturas da extremidade lateral da clavícula promove a estabilização necessária para que haja consolidação sem necessidade de síntese metálica; evita reoperações para retirada do material de síntese; além de ser um procedimento de baixo custo, com boa reprodutibilidade e preservação da articulação acromioclavicular.

Evaluation of the results from arthroscopic surgical treatment of rotator cuff injuries in patients aged 65 years and over.

OBJECTIVES: To evaluate the results from arthroscopic surgical treatment of rotator cuff injuries in patients aged 65 years and over. METHODS: Between 1998 and 2009, 168 patients underwent operations. Five cases were excluded. The remaining 163 patients were stratified according to their age group: 65-69 years (49.1%), 70-74 (26.4%) and 75 years and over (24.5%). Their mean age was 71 years (range: 65-83). There were 63 male patients (38.7%). The mean length of time with pain, from the onset of symptoms to the surgery, was 23 months (range: 2 days to 240 months). Sixty-two patients (38%) reported histories of trauma and 26 (16%) reported that their pain worsened through exertion. RESULTS: From the UCLA criteria, 80.4% of the results were excellent, 16% good, 1.8% fair and 1.8% poor. Complications occurred in 11%. The final clinical result did not show any correlation with age progression, injury size or tendons affected. However, there was a significant association (p < 0.001) between the presence of trauma and larger injuries. The length of time between the onset of symptoms and the surgical procedure had a significant relationship (p < 0.027) with the postoperative results: the longer this time was, the worse the results were. CONCLUSION: Arthroscopic treatment of rotator cuff injuries in patients aged 65 years and over presented excellent and good results in 96.4% of the cases, according to the UCLA assessment, with a low complication rate. Advanced age did not show any influence on the postoperative clinical evolution, but the earlier the surgical treatment was instituted, the better the results were.

OBJETIVOS: Avaliar os resultados do tratamento cirúrgico por via artroscópica nas lesões do manguito rotador (LMR) de pacientes com 65 anos ou mais. MÉTODOS: Entre 1998 e 2009 foram operados 168 pacientes. Cinco casos foram excluídos. Os 163 pacientes foram estratificados de acordo com a faixa etária de 65 a 69 (49,1%), 70 a 74 (26,4%) e acima de 75 (24,5%). A média foi de 71 anos (65 a 83). Eram do sexo masculino 63 pacientes (38,7%). A média de tempo de dor (início dos sintomas) até a cirurgia foi de 23 meses (2d­240 m). Referiram história de trauma 62 pacientes (38%) e 26 (16%) algum esforço com pioria da dor. RESULTADOS: Pelos critérios da Universidade da Califórnia em Los Angeles (UCLA) tivemos 80,4% de excelentes resultados, 16% bons, 1,8% regular e 1,8% ruim. Tivemos 11% de complicações. O resultado clínico final não mostrou correlação com a progressão da idade, o tamanho da lesão ou os tendões acometidos. Mas existe uma associação significativa (p < 0,001) entre a presença de trauma e lesões maiores. O tempo entre o início dos sintomas e o procedimento cirúrgico mostra uma relação significativa (p < 0,027) com os resultados pós-operatórios: quanto maior, piores os resultados. CONCLUSÃO: O tratamento artroscópico da LMR em pacientes com 65 anos ou mais apresentou resultados excelentes e bons em 96,4% quando avaliados pelo UCLA, com baixa taxa de complicações. A idade avançada não demonstrou influência na evolução clínica pós-operatória. Entretanto, quanto mais precocemente o tratamento cirúrgico for instituído, melhores os resultados.

Evaluation of the results and complications of the Latarjet procedure for recurrent anterior dislocation of the shoulder.

OBJECTIVE: Evaluate the results and complications of Latarjet procedure in patients with anterior recurrent dislocation of the shoulder. METHODS: Fifty-one patients (52 shoulders) with anterior recurrent dislocation, surgically treated by Latarjet procedure, were analyzed retrospectively. The average follow-up time was 22 months, range 12-66 months; The age range was 15-59 years with a mean of 31; regarding sex, 42 (82.4%) patients were male and nine (17.6%) were female. The dominant side was affected in 29 (55.8%) shoulders. Regarding the etiology, 48 (92.3%) reported trauma and four (7.6%) had the first episode after a convulsion. RESULTS: The average elevation, lateral rotation and medial rotation of the operated shoulder were, respectively, 146° (60-80°), 59° (0-85°) and T8 (T5 gluteus), with statistical significance for decreased range of motion in all planes, compared with the other side. The scores of Rowe and UCLA were 90.6 and 31.4, respectively, in the postoperative period. Eleven shoulders (21.2%) had poor results: signs of instability (13.4%), non-union (11.5%) and early loosening of the synthesis material (1.9%). There was a correlation between poor results and convulsive patients (p = 0.026). CONCLUSION: We conclude that the Latarjet procedure for correction of anterior recurrent dislocation leads to good and excellent results in 82.7% of cases. Complications are related to errors in technique.

OBJETIVO: Avaliar os resultados e as complicações da cirurgia de Latarjet em pacientes acometidos pela instabilidade recorrente anterior de ombro. MÉTODOS: Foram analisados, retrospectivamente, 51 pacientes (52 ombros) com diagnóstico de luxação recidivante anterior, operados pela técnica de Latarjet. O tempo médio de seguimento foi de 22 meses, variação de 12 a 66 meses; a faixa etária variou de 15 a 59 anos, com média de 31; em relação ao sexo, 42 (82,4%) pacientes eram do masculino e nove (17,6%) do feminino. O lado dominante foi acometido em 29 (55,8%) ombros. Quanto à etiologia, 48 (92,3%) referiram trauma e quatro (7,6%) tiveram o primeiro episódio após um quadro de convulsão. RESULTADOS: As médias de elevação, rotação lateral e rotação medial ativas do membro operado foram, respectivamente, de 146° (60° a 180°), 59° (0° a 85°) e T8 (T5 a glúteo), houve significância estatística quanto à diminuição da amplitude de movimento em todos os planos, quando comparado com o lado contralateral (não operado). As médias de pontuação de Rowe e UCLA foram de 90,6 e 31,4, respectivamente, no período pós-operatório. Onze ombros (21,2%) apresentaram maus resultados: sinais de instabilidade (13,4%), pseudoartrose (11,5%) e soltura precoce do material de síntese (1,9%). Houve correlação entre maus resultados e pacientes convulsivos (p = 0,026). CONCLUSÃO: O procedimento de Latarjet para correção da luxação anterior recidivante leva a bons e excelentes resultados em 82,7% dos casos.

FATTY MUSCLE INFILTRATION IN CUFF TEAR: PRE AND POST OPERATIVE EVALUATION BY MRI.

OBJECTIVE: To evaluate the fatty infiltration and atrophy of the supraespinatus in the pre- and postoperative of a rotator cuff lesion (RCL), by MRI. METHODS: Ten patients with full-thickness rotator cuff tears who had undergone surgical arthroscopic rotator cuff repair between September and December 2011 were included. This is a prospective study, with analysis and comparison of fatty infiltration and atrophy of the supraespinatus. The occupation ratio was measured using the magic selection tool in Adobe Photoshop CS3((r)) on T1 oblique sagittal Y-view MRI. Through Photoshop, the proportion occupied by the muscle belly regarding its fossae was calculated. RESULTS: There was a statistically significant increase in the muscle ratio (p=0.013) comparing images pre and postoperative, analyzed by the Wilcoxon T test. CONCLUSION: The proportion of the supraspinal muscle above the pit increases in the immediate postoperative period, probably due to the traction exerted on the tendon at the time of repair. Level of Evidence II, Cohort Study.

Results of open reduction and internal fixation of severe fractures of the proximal humerus in elderly patients.

OBJECTIVE: To evaluate clinical and radiological results with open reduction and internal fixation of severe fractures of the proximal humerus in the patients over the age of 60 years. METHODS: Between June 1992 and February 2011, 21 patients with FGEPU over the age of 60 years were treated by open reduction and internal fixation at the Group of Shoulder and Elbow Department of Orthopaedics and Traumatology of Santa Casa de São Paulo Medical School. 18 patients were reviewed. RESULTS: Two patients had excellent results, 12 good, three regular and one bad. Therefore, we find that 77.7% of these had good and excellent results. All patients were satisfied with the treatment and only three patients did not return to previous activities. Mean postoperative mobilities were 122° elevation (90-150°), 39 lateral rotation (20-60°) and medial rotation of T11 (T5 to sacro iliac joint). CONCLUSION: Open reduction and internal fixation of FGEPU may also be indicated for elderly patients and obtained 77.7% of good and excellent results. Statistically (p < 0.05), the anatomical reduction of the fracture was found to be important for obtaining good results.

OBJETIVO: avaliar clinica e radiologicamente os resultados obtidos com a redução aberta e a fixação interna das fraturas graves da extremidade proximal do úmero (FGEPU) na população com idade igual ou superior a 60 anos. MÉTODOS: entre junho de 1992 e fevereiro de 2011, o Grupo de Ombro e Cotovelo do Departamento de Ortopedia e Traumatologia da Faculdade de Ciências Médicas da Santa Casa de São Paulo tratou, com redução aberta e fixação interna, 21 pacientes com FGEPU e com idade superior a 60 anos. Desses, 18 foram reavaliados. RESULTADOS: dois pacientes evoluíram com resultados excelentes, 12 bons, três regulares e um ruim. Portanto, verificamos que 77,7% evoluíram com bons e excelentes resultados. Todos os pacientes estavam satisfeitos com o tratamento e apenas três não retornaram às atividades prévias. As médias de mobilidade pós­operatória foram de 122° de elevação (90°­150°), 39° de rotação lateral (20°­60°) e T11 de rotação medial (T5 a Glúteo). CONCLUSÃO: a redução aberta e a fixação interna das FGEPU podem ser indicadas também para pacientes idosos e obtivemos 77,7% de bons e excelentes resultados. Estatisticamente (p < 0,05), a redução anatômica da fratura mostrou­se importante para a obtenção de bons resultados.

Osteoid osteoma of the acromion simulating acromioclavicular pain.

The osteoid osteoma is a benign bone tumour that usually presents with nocturnal pain in young adults, relieved by rest and anti-inflammatories. It can affect any bone; however, their occurrence is rare in the acromion. The authors describe a case of osteoid osteoma located in the acromion, with symptoms that simulated acromion claviculararthrosis. The diagnosis was made by CT scan and treatment was excision of the nidus through arthroscopy. The diagnosis was confirmed by histopathology. In the outpatient segment, the patient remained asymptomatic, with complete recovery of function of the affected limb.

O osteoma osteóide é um tumor ósseo benigno que se apresenta geralmente em adultos jovens com dor noturna, aliviada por repouso e anti­inflamatórios. Pode acometer qualquer osso. Entretanto, sua ocorrência no acrômio é rara. Os autores descrevem um caso de osteoma osteóide localizado no acrômio, com sintomas que simulavam artrose acrômio­clavicular. O diagnóstico foi feito por meio de tomografia computadorizada e o tratamento proposto foi a exérese do nidus por meio de artroscopia. O diagnóstico definitivo foi confirmado por exame histopatológico. No segmento ambulatorial, a paciente permaneceu assintomática e com recuperação completa da função do membro acometido.

OBJECTIVE: to functionally evaluate patients with injury of the distal insertion of the biceps brachii muscle that was treated surgically. METHODS: between April 2002 and June 2011, 15 elbows of 14 patients underwent surgical treatment performed by the Shoulder and Elbow Surgery Group, Department of Orthopedics and Traumatology, School of Medical Sciences, Santa Casa de São Paulo. The minimum follow-up was six months, with a mean of 28 months. The patients' ages ranged from 28 to 62 years, with a mean age of 40 years. All the patients were male and the dominant arm was affected in 64.2%. The clinical evaluation on the results was conducted using the criteria of the American Medical Association (AMA), as modified by Bruce, with evaluation of the joint range of motion (flexion-extension and pronosupination), the presence of pain and the patient's degree of satisfaction. RESULTS: from the AMA criteria, as modified by Bruce, we obtained 100% satisfactory results, of which 85.7% were considered to be excellent and 14.3% good. We observed that when distal injuries of the biceps brachii muscle affected young and active patients, surgical treatment was a good option.

OBJETIVO: avaliar funcionalmente os pacientes com lesão da inserção distal do músculo bíceps braquial tratados cirurgicamente. MÉTODOS: entre abril de 2002 e junho de 2011, 15 cotovelos de 14 pacientes foram submetidos a tratamento cirúrgico pelo Grupo de Cirurgia de Ombro e Cotovelo do Departamento de Ortopedia e Traumatologia da Faculdade de Ciências Médicas da Santa Casa de São Paulo. O seguimento mínimo foi de seis meses, com média de 28. A idade variou de 28 a 62 anos, com média de 40. Todos os pacientes eram do sexo masculino e o membro dominante foi acometido em 64,2%. A avaliação clínica dos resultados foi feita pelos critérios da American Medical Association (AMA), modificados por Bruce, pelo grau de amplitude articular (flexoextensão e pronossupinação), pela presença de dor e pelo grau de satisfação do paciente. RESULTADOS: pelos critérios da AMA, modificados por Bruce, obtivemos 100% de resultados satisfatórios, 85,7% considerados excelentes e 14,3% bons. Observamos que quando as lesões distais do músculo bíceps braquiais acometem pacientes jovens e ativos, o tratamento cirúrgico é uma boa opção.

Functional evaluation of arthroscopic repair of rotator cuff injuries in patients with pseudoparalysis.

OBJECTIVE: to evaluate the functional result from arthroscopic repair of rotator cuff injuries in patients with pseudoparalysis, defined as incapacity to actively raise the arm above 90°, while complete passive elevation was possible. METHODS: we reevaluated 38 patients with a mean follow-up of 51 months (minimum of 24). We analyzed the pseudoparalysis reversion rate and the functional result obtained. RESULTS: according to the assessment criteria of the University of California in Los Angeles (UCLA), 31 (82%) patients had good and excellent results, two (5%) had fair results and five (13%) had poor results. The mean active elevation went from 39° before the operation to 139° after the operation (p < 0.05); the mean active lateral rotation went from 30° to 48° (p < 0.05) and the mean active medial rotation went from level L3 to T12 (p < 0.05). CONCLUSION: arthroscopic repair of rotator cuff injuries produced good and excellent results in 82% of the cases and a statistically significant improvement of active range of motion, with reversion of the pseudoparalysis in 97.4% of the cases. It is therefore a good treatment option.

OBJETIVO: avaliar o resultado funcional do reparo artroscópico das lesões do manguito rotador em pacientes com pseudoparalisia, definida como incapacidade de elevação ativa do braço acima de 90°, com elevação passiva completa. MÉTODOS: reavaliamos 38 pacientes com média de seguimento de 51 meses (mínimo de 24). Analisamos a taxa de reversão da pseudoparalisia e o resultado funcional obtido. RESULTADOS: pelos critérios de avaliação da Universidade da Califórnia em Los Angeles (Ucla), 31 (82%) pacientes tiveram bons e excelentes resultados; dois (5%) resultados regulares e cinco (13%) ruins. A média da elevação ativa passou de 39° no pré-operatório para 139° no pós-operatório (p < 0,05), a média da rotação lateral ativa passou de 30° para 48° (p < 0,05) e a média da rotação medial ativa passou do nível L3 para o T12 (p < 0,05). CONCLUSÃO: o reparo artroscópico das lesões do manguito rotador proporcionou bons e excelentes resultados em 82% dos casos e uma melhoria, estatisticamente significativa, da amplitude de movimento (ADM) ativa, com reversão da pseudoparalisia em 97,4% dos casos. É, portanto, uma boa opção de tratamento.

Evaluation of the results from surgical treatment of the terrible triad of the elbow.

OBJECTIVE: to evaluate the results from surgical treatment of the terrible triad of the elbow (fracture of the radial head, fracture of the coronoid process and elbow dislocation) and its complications. METHODS: between August 2002 and August 2010, 15 patients (15 elbows) with the terrible triad were treated by the Shoulder and Elbow Group of the Department of Orthopedics and Traumatology, School of Medical Sciences, Santa Casa de São Paulo. Nine (60%) were male and six (40%) were female; their ages ranged from 21 to 66 years, with a mean of 41 years. With the exception of one case that underwent arthroscopic surgery, all the patients underwent open surgery. The fracture of the coronoid process was fixed in 10 patients (66.7%). The fracture of the radial head was treated by means of internal osteosynthesis in 11 cases (73.3%); in three cases (20%), the radial head was resected; and in one case, only the fragment of the fracture was resected. The collateral ligaments, except for one case, were repaired whenever they were found to be injured; ten cases (66.7%) of medial collateral injury and 15 (100%) of lateral collateral injury were found. The mean length of the postoperative follow-up was 62 months, with a minimum of 12 months. The postoperative evaluation was done by means of the Bruce score. RESULTS: more than 80% of the patients recovered their functional ranges of motion but, according to the Bruce score, only 26% of the patients achieved results that were considered satisfactory. CONCLUSION: despite the unsatisfactory results, the functional ranges of motion and elbow function could be restored.

OBJETIVO: avaliar o resultado do tratamento cirúrgico da tríade terrível do cotovelo (fratura da cabeça do rádio e do processo coronoide e luxação do cotovelo) e suas complicações. MÉTODOS: entre agosto de 2002 e agosto de 2010 foram tratados 15 cotovelos (15 pacientes) com tríade terrível pelo Grupo de Ombro e Cotovelo do Departamento de Ortopedia e Traumatologia da Faculdade de Ciências Médicas da Santa Casa de São Paulo. Nove (60%) eram do sexo masculino e seis (40%) do feminino; a idade variou de 21 a 66, com média de 41. Com a exceção de um caso, que foi submetido a cirurgia artroscópica, todos foram submetidos a cirurgia aberta. A fratura do processo coronoide foi fixada em 10 pacientes (66,7%). A fratura da cabeça do rádio foi submetida a osteossíntese interna em 11 casos (73,3%); em três (20%), a cabeça do rádio foi ressecada; em um caso, somente o fragmento da fratura foi ressecado. Os ligamentos colaterais, com exceção de um caso, foram reparados sempre que se encontrassem lesados; foram encontradas 10 (66,7%) lesões do colateral medial e 15 (100%) do lateral. O seguimento no período pós­operatório foi, em média, de 62 meses, com mínimo de 12. A avaliação pós­operatória foi feita por meio do escore de Bruce. RESULTADOS: mais de 80% dos pacientes recuperaram os arcos de movimentos funcionais e, de acordo com o escore de Bruce, apenas 26% obtiveram resultados considerados satisfatórios. CONCLUSÃO: apesar dos resultados insatisfatórios, os arcos funcionais de movimento e a função do cotovelo podem ser restaurados.

Biomechanical evaluation between the modified Mason-Allen stitch and the locked double-tie stitch on the infraspinatus of sheep.

OBJECTIVES: To evaluate and compare the in vitro biomechanical results from two stitches: the Mason-Allen stitch, as modified by Habermeyer; and the locked double-tie stitch developed at our service, on tendons of the infraspinatus muscle of sheep. METHODS: Twenty tendons from the infraspinatus muscle of sheep were randomly divided into two groups: LDT, on which the locked double-tie stitch was performed; and MA, with the modified Mason-Allen stitch. The evaluation was performed in the mechanics laboratory, using a standard test machine with unidirectional traction, constant velocity of 20 mm per second and a 500 N load cell, without force cycling. RESULTS: We observed that LDT was superior to MA, for the force needed to form spaces of both 5 mm (p = 0.01) and 10 mm (p = 0.002) and also for the maximum traction resistance (p = 0.003). CONCLUSION: We confirmed our hypothesis that LDT stitches are superior to MA stitches from a biomechanical point of view. This is a further stitching option for surgeons, when fragile and poorly vascularized tendons need to be sutured, and it improves the quality of fixation without increasing the "strangulation" and, consequently, the ischemic area.

OBJETIVOS: Avaliar e comparar os resultados biomecânicos in vitro de dois pontos: o Mason-Allen modificado por Habermeyer e o ponto duplo-laço bloqueado (DLB), desenvolvido no nosso serviço em tendões de músculos infraespinais de ovinos. MÉTODOS: Vinte tendões do músculo infraespinal de ovinos foram divididos aleatoriamente em dois grupos: o DLB, no qual foi confeccionado o ponto duplo-laço bloqueado; e o MA, com o ponto Mason-Allen modificado. A avaliação foi feita no laboratório de mecânica, com uma máquina de teste padrão, de tração unidirecional, com velocidade constante de 20 mm por segundo, com uma célula de carga de 500 N, sem ciclagem de força. RESULTADOS: Evidenciamos uma superioridade do DLB sobre o MA, tanto na força necessária para formar 5 mm de espaço (p = 0,01) como 10 mm (p = 0,002) e também na resistência máxima de tração (p = 0,003). CONCLUSÃO: Confirmamos nossa hipótese de que o ponto com DLB é superior ao MA do ponto de vista biomecânico. Essa é mais uma opção de ponto para o cirurgião, quando precisa suturar tendões frágeis e pouco vascularizados, e melhora a qualidade da fixação sem aumentar o "estrangulamento" e, consequentemente, a área isquêmica.

REASSESSMENT OF PAINFUL SHOULDERS AMONG BASEBALL PLAYERS AFTER CONSERVATIVE TREATMENT.

OBJECTIVE: The objective of this study was to evaluate the rehabilitation results among baseball players who presented pain and medial rotation deficit in their shoulders. METHODS: Out of 55 baseball players assessed between April and June 2009, it was observed that 20 presented pain at some instant during throwing movements. They were advised to undergo a rehabilitation program with exercises to stretch the posterior capsule and reinforce the muscles of the scapular belt, especially the lateral rotators. Eighteen patients followed the advice, while two were lost from the follow-up. The parameters evaluated were: pain, range of motion, strength before the program and strength after the end of the program. RESULTS: Comparing the initial and final assessments, we observed mean increases as follows: 10° of elevation (p = 0.001); three vertebral levels of medial rotation (p < 0.001); 20° of medial rotation at 90° abduction (p < 0.001); and 26° of range of motion (p < 0.001). Regarding strength, elevation force increased by 3 kgf (p = 0.002) and lateral rotation force increased by 1 kgf (p = 0.020). Out of the 18 baseball players studied, the pain level improved in 16, while two continued to present pain and underwent magnetic resonance imaging, which showed lesions for surgical treatment. CONCLUSION: The rehabilitation program conducted among the baseball players was effective and enabled increases in medial rotation, elevation, range of motion and strength of elevation and lateral rotation, consequently producing pain improvements in most of the players.
