Trends in Proximal Interphalangeal and Metacarpophalangeal Joint Arthroplasty Utilization Using Statewide Databases.

Arthritis can have profound debilitating effects on the hand secondary to finger deformities and pain. Arthroplasty of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) can be performed to reduce pain while maintaining joint range of motion. We used outpatient surgery registries from the states of California and Florida to assess the trends of arthroplasty across several recent years and to determine if the outcomes differ based on disease etiology. We found that there has been a steady decline in number of MCP arthroplasty procedures performed annually between 2005 and 2011 while PIP arthroplasty procedures peaked in 2007 and have since also declined. There was an overall complication rate of 2.4% and no difference in cardiac, respiratory, deep venous thrombosis and infection between patients with osteoarthritis and other arthritic etiologies. However, the risk of device failure in patients with rheumatoid arthritis is found to be significantly higher than for patients with osteoarthritis ( < 0.01). PIP and MCP arthroplasty are safe procedures with an overall low complication rate. The increased risk of device related complications observed in patients with rheumatoid arthritis can be used to appropriately counsel this patient population regarding post-operative expectations and prognosis.
