Wagner ER, et al. - In patients older than and younger than 60 years, the contributors intended to compare the outcomes of proximal interphalangeal (PIP) arthroplasty. Two hundred and ninety nine consecutive, primary PIP arthroplasties were performed over a 14-year period, along with 126 arthroplasties performed in patients younger than 60 years. A higher rate of posttraumatic and inflammatory arthritis was observed inn younger patients group. Although risk of revision surgery was increased in posttraumatic arthritis, silicone implants decreased the risk. Dislocation was the most common complication noticed in young patients. Significant improvement in pain levels in patients younger than 60 years with maintained PIP range of motion and pinch strength were noted. However, older patients had improved PIP motion in comparison to younger patients. Higher revision rates after PIP arthroplasty, particularly in the posttraumatic setting were lead by younger age.
