We present long-term results for the Pyrocardan®, a pyrocarbon trapeziometacarpal interposition implant used for the treatment of osteoarthritis of the thumb.
Between March 2009 and May 2013, 199 arthroplasties were performed in a single hand center, in 184 patients by 6 hand surgeons. 107 implants were followed up for a mean 137 months (range, 120-168 months). 82 patients (89 implants) were lost to follow-up.
Median age was 57 years, with 15 patients (14.2%) aged ≤50 years. At last follow-up, functional scores were significantly improved compared to preoperative data: pain rating, 0.4/10 versus 7.2/10; Patient-Rated Wrist/Hand Evaluation, 4/100 versus 61/100; Quick Disabilities of the Arm, Shoulder and Hand, 9/100 versus 54/100. Range of motion and strength were comparable to the contralateral side. Radiographic analysis showed that 82% of implants were correctly positioned. No implant dislocation was observed. There were 6 re-operations, 5 of which in the short term. Overall implant survival was 94.3%, with 44.7% loss to follow-up.
Pyrocardan® interposition arthroplasty is a valid alternative for the treatment of osteoarthritis of the thumb.

我们展示了Pyrocardan®（一种用于治疗拇指骨关节炎的热解碳梯形掌骨间植入物）的长期疗效。
2009年3月至2013年5月期间，在一个手部中心由6名手外科医生为184例患者进行了199例关节成形术。对107枚植入物进行了平均137个月（范围为120 - 168个月）的随访。82例患者（89枚植入物）失访。
中位年龄为57岁，15例患者（14.2%）年龄≤50岁。在最后一次随访时，与术前数据相比，功能评分显著改善：疼痛评分，0.4/10 vs 7.2/10；患者自评腕/手评估，4/100 vs 61/100；手臂、肩部和手部快速残疾评定，9/100 vs 54/100。活动范围和力量与对侧相当。影像学分析显示82%的植入物位置正确。未观察到植入物脱位。有6例再次手术，其中5例在短期内进行。总体植入物生存率为94.3%，44.7%失访。
Pyrocardan®间置关节成形术是治疗拇指骨关节炎的一种有效替代方法。
