Functional and Radiological Outcomes of the Surgical Treatment of Acute Acromioclavicular Dislocation with Anchors Associated with Clavicle and Scapula Fixation / Resultados funcionais e radiológicos do tratamento cirúrgico da luxação acromioclavicular aguda com âncoras e fixação clavículo-escapular

Abstract Objective To evaluate the clinical, radiological and functional results of the surgical treatment of acute acromioclavicular dislocation using a coracoclavicular fixation technique (syndesmopexy) with two metallic anchors, temporary clavicle and scapula fixation, and transfer of the coracoacromial ligament. Methods Longitudinal observational study of 30 patients with diagnoses of acute acromioclavicular dislocation, who were submitted to surgical treatment with a minimum follow-up of six months, and who were evaluated clinically, radiologically, and by the University of California at Los Angeles (UCLA), the Disabilities of the Arm, Shoulder and Hand (DASH) and the Constant-Murley functional scores. Results The mean values of the scores were: UCLA = 32; DASH = 11.21; and Constant-Murley = 86.93, with satisfactory results higher than 80%. The unsatisfactory results were associated with acromioclavicular pain on palpation, positive subacromial impingement tests, and older age group, presenting statistical significance (p < 0.05). Radiologically, higher values on account of the coracoclavicular distance ratio from the operated shoulder compared to the normal shoulder were related to worse outcomes, but with no statistically significant difference. No associations were found between the results of the functional scores and the variables degree of the injury, coracoacromial ligament transfer, clinical impression of loss of reduction and scapulothoracic dyskinesis. Conclusion The technique used provides an efficient fixation, with a high level of satisfaction according to the UCLA, Constant-Murley and DASH scores; moreover, it has a low complication rate, despite the high rate of residual radiological acromioclavicular subluxation.

Resumo Objetivo Avaliar os resultados clínicos, radiológicos, e funcionais do tratamento cirúrgico da luxação acromioclavicular aguda, utilizando a técnica de sindesmopexia coracoclavicular com duas âncoras metálicas, fixação temporária clavículo-escapular, e transferência do ligamento coracoacromial. Métodos Estudo observacional longitudinal com trinta pacientes com diagnóstico de luxação acromioclavicular aguda submetidos à cirurgia, com seguimento mínimo de seis meses, avaliados clínica, radiograficamente, e pelos escores de University of California at Los Angeles (UCLA), Disabilities of the Arm, Shoulder and Hand (DASH) e Constant-Murley. Resultados Os valores médios dos escores foram: UCLA = 32; DASH = 11,21; e Constant-Murley = 86,93, com resultados satisfatórios acima de 80%. Os resultados insatisfatórios foram relacionados à dor acromioclavicular, a testes de impacto subacromial positivos, e aos pacientes de faixa etária mais elevada (p < 0,05). Radiologicamente, valores maiores em razão da distância coracoclavicular do ombro operado, comparado com o ombro normal, foram relacionados a piores resultados, embora sem significância estatística. Não foi observada associação entre os resultados dos escores funcionais e as variáveis grau da lesão, transferência do ligamento coracoacromial, impressão clínica de perda de redução, e discinesia escapulo-torácica. Conclusão A técnica utilizada propicia uma fixação eficiente, com alto índice de satisfação segundo os escores de UCLA, Constant-Murley e DASH. Observou-se baixo índice de complicações apesar da frequência elevada de subluxação acromioclavicular radiológica residual.

Functional and radiological evaluation of acute acromioclavicular dislocation treated with anchors without eyelet: comparison with other techniques / Avaliação funcional e radiológica da luxação acromioclavicular aguda reparada com âncoras sem eyelet: comparação com outras técnicas

ABSTRACT OBJECTIVE: To assess the repair results of acromioclavicular dislocations (ACJD) grades III and V, with anchors without eyelet, when compared with other techniques, and to evaluate factors that can affect the final result. METHODS: A retrospective study of 36 patients with ACJD grades III and V in the Rockwood classification, 12 treated with anchors without eyelet, 11 with one tightrope, six with two tightropes, and six with subcoracoid cerclage, operated from September 2012 to February 2015. Patients were assessed radiographically and through DASH, UCLA, the visual analog scale of pain (VAS) and the Short-Form 36 (SF-36). Surgical time and the possible influence of some factors in the outcome were also assessed. RESULTS: The mean DASH score was 6.7; UCLA, 32.9; VAS, 1.2; and SF-36, 79.47. Radiographically, the final mean measurement was 9.93 mm, with no statistical difference between the groups. The mean surgical time for Group I was 31 min; Group II, 19 min; Group III, 29 min; and Group IV, 59 min. There was a significant difference between Groups II and IV when compared with the study group. The initial and immediate post-operative ACJD measurements ACJD were correlated with the final measure. CONCLUSION: The repair of acute ACJD with anchors without eyelet is as effective as the other methods, with significantly shorter operative time when compared with the subcoracoid cerclage technique. The final radiological result is influenced by the coracoclavicular initial distance and the immediate postoperative measurement.

RESUMO OBJETIVO: Avaliar os resultados do reparo das luxações acromioclaviculares (LAC) graus III e V, com âncoras sem eyelet, e comparar com outras técnicas, bem como fatores que possam interferir no resultado final. MÉTODOS: Estudo retrospectivo de 35 pacientes com LAC grau III e V, pela classificação de Rockwood, 12 tratados com âncoras sem eyelet, 11 com um Tightrope, seis com dois Tightropes e seis com amarrilho subcoracoide, operados de setembro de 2012 a fevereiro de 2015. Os pacientes foram avaliados radiograficamente e pelos escores de DASH, UCLA, pela escala visual analógica de dor (EVA) e pelo Short-Form 36 (SF36). O tempo cirúrgico e a possível interferência de alguns fatores no resultado final também foram avaliados. RESULTADOS: A média dos escores foi de 6,7 no DASH; 32,9 no UCLA; 1,2 na EVA e 79,47 no SF-36. Radiograficamente, a medida final média entre o coracoide e a clavícula foi de 9,93 mm, sem diferença estatística entre os grupos. Quanto ao tempo cirúrgico, a média do grupo I foi de 31 minutos; do grupo II, 19 minutos; do grupo III, 29 minutos e do grupo IV, 59 minutos, houve diferença significativa entre os grupos II e IV, quando comparados com o grupo em estudo. A medida inicial da LAC e a medida pós-operatória imediata (POI) tiveram correlação com a medida final. CONCLUSÃO: O reparo da LAC aguda com âncoras sem eyelet é tão eficaz quanto outros métodos e com tempo cirúrgico significativamente menor quando comparado com a técnica de amarrilho subcoracoide. O resultado radiológico final é influenciado pela distância coracoclavicular inicial e do POI.

Long-Term Follow-up of Polypropylene Bone Anchored Slings

Introduction The transvaginal bone anchored polypropylene sling (BAS) has proven to be a successful treatment for patients with SUI. However, there is limited data on long-term outcomes following BAS with polypropylene mesh. We report our series of patients who had at least 3 years of follow-up after placement of BAS. Materials and Methods A retrospective review of prospectively collected data of patients undergoing BAS for stress urinary incontinence (SUI) with minimum 3 year follow-up was performed. Outcomes and complications were determined from annual mailed post-operative questionnaires. Results 142 patients who had undergone BAS and had answered post-operative questionnaires at a minimum of 3 years were identified. Average follow-up was 58 months (range 36-97 months). The overall success rate was 71% with a dry rate of 27%. Complications occurred in 9% of patients, more commonly in patients without a history of anti-incontinence procedure. Conclusions Although less commonly used, BAS with polypropylene mesh is associated with an acceptable success rate at long term follow-up but a low completely dry rate. .

Combinación de técnicas para el mejor resultado a largo plazo en la cirugía vascular: manejo "no touch" en la disección del injerto venoso: implantación y distensión por columna de sangre arterializada a presión fisiológica: más sutura a doble anclaje / Combination of techniques for the best result in the long term in vascular surgery: no touch management in the dissection of venous graft, implantation and distention by arterializeb blood physiological pressure column, plus a doble anchor suture

Se realiza un estudio en 11 pacientes escogidos al azar para cirugía vascular. 6 presentaban enfermedad renal en hemodiálisis que requerían de una fístula arteriovenosa; 2 sufrieron trauma vascular complejo y 3 presentaban enfermedad ateroesclerótica severa con daños isquémicos. Se les aplicó un procedimiento combinado de técnicas de minimo daño endotelial que disminuyeran la hiperplasia neointimal y la pérdida de permeabilidad a largo plazo. Se aplicó la toma del injerto venoso por la técnica de "no touch", anastomosis de doble anclada y llenado venoso con columna de sangre y presión propias del paciente. Los pacientes fueron seguidos por un periodo minimo de 6 meses y máximo de 10 años. Los resultados fueron alentadores con alta tasa de permebilidad en el tiempo. Creemos que la aplicación de técnicas que remeden lo mejor posible la anatomía y fisiología en el tratamiento de las enfermedades vasculares, se obtendrían resultados excelentes a largo.

This is an investigation in the camp of physilogical vascular surgery. Were included II patients, between 1996 to 2006. 6 sulfered chronic renal diseases submitted to hemodialisis, 2 with severe and complex vascular trauma and 3 suffering peripheral artery diseases with ischemic lesion. All of them were submitted to surgical techniques that diminished endothelial damage, intimal hyperplasia and permit a long time successful in vessel permeability. the patients were followed in a term of 6 month to 10 years. The vesses permeability rare was high.
