ABSTRACT
Abstract The authors present an atypical case of a left elbow complex fracture with extensive loss of bone and muscle tissue. The patient was submitted to several surgical procedures, which resulted in a total arthroplasty of the left elbow with triceps reconstruction using a semitendinosus muscle tendon graft.
Resumo Os autores apresentam um caso atípico de fratura complexa do cotovelo esquerdo com perda extensa de tecido ósseo e muscular. O paciente foi submetido a diversos procedimentos cirúrgicos, que resultaram em uma artroplastia total do cotovelo esquerdo associada à reconstrução do tríceps com enxerto do tendão do músculo semitendíneo.

Total elbow arthroplasty is a common surgical procedure used in the management of advanced rheumatoid arthritis, posttraumatic arthritis, osteoarthritis, and unfixable fracture in elderly patients. Total elbow prostheses have evolved over the years and now include the linked, unlinked, and convertible types. However, long-term complications, including infection, aseptic loosening, instability, and periprosthetic fracture, remain a challenge. Here, we introduce each type of implant and evaluate clinical outcomes and complications by reviewing the previous literature.

PURPOSE: Understanding elbow biomechanics is necessary to understand the pathophysiologic mechanism of elbow injury and to provide a scientific basis for clinical practice. This article provides a summary of key concepts that are relevant to understanding common elbow injuries and their management. MATERIALS AND METHODS: The biomechanics of the elbow joint can be divided into kinematics, stability and force transmission through the elbow joint. Active and passive stabilizers include bony articular geometry; soft tissues provide joint stability, compression force and motion. RESULTS AND CONCLUSION: Knowledge of elbow biomechanics will help (i) advance surgical procedures and trauma management, (ii) develop new elbow prostheses and (iii) stimulate future research.
