In 2012, our unit published our experience with a pyrocarbon proximal interphalangeal joint (PIPJ) implant. Due to high subsidence rates, a decision was made to change to a cemented surface replacement proximal interphalangeal joint (SR-PIPJ) implant. The purpose of this study was to assess whether the change to a cemented implant would improve the subsidence rates. : Retrospective review of all patients who had a cemented SR-PIPJ arthroplasty performed from 2011 to 2013 with at least 12 months follow-up. A total of 43 joints were included with an average follow-up of 26.5 months. There was a significant ( = .02) improvement in arc of motion with an average satisfaction score of 3.3 (satisfied patient). Subsidence was noted in 26% of joints with a significant difference in range of motion ( = .003) and patient satisfaction ( = .001) between the group with and without subsidence. : The change to a cemented implant resulted in satisfied patients with an improvement in range of motion. The rate of subsidence improved but remains unacceptably high.
2012年，我们单位发表了关于热解碳近端指间关节（PIPJ）植入物的经验。由于下沉率较高，决定改用骨水泥固定表面置换近端指间关节（SR-PIPJ）植入物。本研究的目的是评估改用骨水泥固定植入物是否会提高下沉率。：回顾性分析2011年至2013年期间接受骨水泥固定SR-PIPJ关节成形术且随访至少12个月的所有患者。共纳入43个关节，平均随访26.5个月。运动弧有显著改善（=0.02），平均满意度评分为3.3（患者满意）。26%的关节出现下沉，有下沉和无下沉组之间的运动范围（=0.003）和患者满意度（=0.001）存在显著差异。：改用骨水泥固定植入物使患者满意，运动范围得到改善。下沉率有所改善，但仍高得令人无法接受。
