Fracture base of fifth metacarpal
a. Wrist pain during attempted push-ups or diffuse swelling on the dorsum of the wrist may be caused by a variety of factors.
b. Wrist popping on movement may be the result of carpal instability, subluxation of a tendon on extension and flexion of the wrist, or intra-articular problems such as an articular cartilage flap or a tear of the triangular fibrocartilage.
c. Localized tenderness at the anatomic snuffbox (scaphoid) is the most consistent sign of scaphoid fracture.
