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

Se presenta una descripción detallada de la reconstrucción artroscópica de un defecto posterior de glena con injerto autólogo tricortical de cresta iliaca en la posición de decúbito lateral. A nuestro entender esto no se ha publicado previamente en la literatura. Se han descripto diferentes técnicas quirúrgicas para el tratamiento de la inestabilidad posterior recurrente de hombro. Algunas abordan los tejidos blandos como la capsulorrafia abierta o artroscópica, otras como las osteotomías glenoideas o la colocación de un injerto óseo posterior, abordan la anatomía ósea. Este trabajo muestra que la colocación artroscópica de un injerto óseo posterior es segura y reproducible. La misma permite el posicionamiento y la colocación adecuada del injerto y podría potencialmente reducir el riesgo de lesión de estructuras neurovasculares, las estructuras musculotendinosas posteriores y problemas cutáneos debido a la técnica mínimamente invasiva. Adicionalmente, los scores funcionales y el rango de movilidad mejoran rápidamente y el paciente pudo volver rápidamente a la competencia. Tipo de estudio: Reporte de Caso. Nivel de evidencia: V


In this case report we present a detailed description of an arthroscopic reconstruction of a posterior glenoid defect with iliac bone graft with the decubitus lateral position. To our knowledge this was not previously reported. Various surgical techniques have been described for the treatment of recurrent posterior shoulder instability. Some address the soft tissues, such as open or arthroscopic capsulorrhaphy, others, such as glenoid osteotomy and the posterior bone graft procedure, address the bony anatomy. Placement of a bone block on the posterior glenoid rim increases the posterior glenoid surface and improves stability. This study shows that arthroscopic posterior bone graft procedure is safe and reproducible. It allows accurate positioning and healing of the posterior bone block, and it could potentially reduce the risk of injury of neurovascular structures, the posterior musculotendinous structures, and skin problems due to the minimally invasive technique. Further, functional scores and ROM improved quickly and the patient was able to rapidly return to competitive sports. Type of study: Case report. Level of evidence: V
