Isolated palmar dislocation of the trapezoid associated with distal radius fracture in a patient with major trauma: A case report and literature review.

Abstract Trapezoid dislocation is infrequent, and palmar trapezoid dislocation is even more rare. This uncommon injury is associated with high-energy trauma and is often combined with other distracting injuries that may lead to misdiagnosis or delayed diagnosis. We present a case of isolated palmar dislocation of the trapezoid in a 49-year-old man with major trauma following a motor vehicle accident. We identified the dislocation by radiograph and performed open reduction and internal fixation (ORIF) after primary management of his major trauma. The patient recovered with satisfactory hand and wrist function. We share our experience and review the pitfalls in diagnosis and treatment for this rare injury.
