This is a retrospective study to evaluate the outcome of volar plate interposition arthroplasty for proximal interphalangeal joint post-traumatic osteoarthritis with a minimum 5-year follow-up. We identified patients receiving volar plate interposition arthroplasty for post-traumatic osteoarthritis in proximal interphalangeal joints. The measurements included the numeric pain scale (on a scale of 0-10), the proximal interphalangeal joint active range of motion, the Michigan Hand Outcomes Questionnaire, the perioperative radiograph of the involved digit, proximal interphalangeal joint stability, and pinch strength. Eight patients with a median age of 44 years old (interquartile range (IQR): 29.3-56.8) were included in this study. The median follow-up period was 6.5 years (range of 5-11 years). The median numeric pain scale improved from 5 (IQR: 4.3-6.0) preoperatively to 0 (IQR 0-0.8) at the follow-up evaluation ( = 0.011). All digits demonstrated stability during manual stress testing compared to their noninjured counterparts. The median active proximal interphalangeal joint arc of motion improved from 25° to 55° ( = 0.011). The pinch strength of the fingers on the injured hand was weaker than those on the contralateral hand (2.2 Kg vs. 3.7 Kg, = 0.012). We suggested that volar plate interposition arthroplasty may be an alternative surgical option for post-traumatic osteoarthritis in the proximal interphalangeal joints.
这是一项回顾性研究，旨在评估掌板置入关节成形术治疗近端指间关节创伤后骨关节炎的疗效，随访时间至少为5年。我们纳入了接受掌板置入关节成形术治疗近端指间关节创伤后骨关节炎的患者。测量指标包括数字疼痛量表（0-10分）、近端指间关节主动活动范围、密歇根手功能结果问卷、患指的围手术期X线片、近端指间关节稳定性和捏力。本研究纳入了8例患者，中位年龄为44岁（四分位间距（IQR）：29.3-56.8）。中位随访期为6.5年（5-11年）。数字疼痛量表的中位数从术前的5分（IQR：4.3-6.0）改善至随访评估时的0分（IQR 0-0.8）（P = 0.011）。与未受伤的对应手指相比，所有手指在手动应力测试中均表现出稳定性。近端指间关节主动活动弧度的中位数从25°改善至55°（P = 0.011）。患手手指的捏力弱于对侧手（2.2千克 vs. 3.7千克，P = 0.012）。我们认为掌板置入关节成形术可能是近端指间关节创伤后骨关节炎的一种替代手术选择。
