Treatment of closed articular fractures of the metacarpophalangeal and proximal interphalangeal joints.

One hundred thirty-four closed articular fractures of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints were reviewed to identify common fracture patterns, assess results, and define the most successful methods of treatment. Articular involvement greater than 20 per cent and displacement more than 1 to 2 mm usually requires open reduction and internal fixation. Fracture involvement and displacement were better tolerated by the MCP than PIP joint. Problem fractures and treatment recommendations are discussed.
