Trapezoid Stress Fracture in an Olympic-Level Gymnast: A Case Report

Case:
A 23-year-old elite-level gymnast presented with insidious-onset pain near the base of the second metacarpal. The patient was found to have a trapezoid stress fracture and was treated nonoperatively in a thumb spica cast for 4 weeks. He resumed gymnastics without limitations 8 weeks from the time of diagnosis.
Conclusion:
Trapezoid stress fractures must be considered when evaluating patients presenting with pain about the base of the index finger metacarpal, particularly those who perform activities that repetitively place high loads across the wrist. Wrist immobilization and a supervised return to participation resulted in an excellent outcome for this patient.

Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
