Arthritis and instability of the finger joints of the hand leads to chronic pain and decreased hand function. In such patients, arthrodesis is a generally accepted surgical treatment. Various techniques are available for arthrodesis of interphalangeal and thumb metacarpophalangeal joints of the hand. We present our experience from 7 patients being treated with interphalangeal and thumb metacarpophalangeal arthrodesis using an intramedullary implant (X-Fuse).Clinical parameters such as finger stability, soft-tissue irritation, infection rate, and nail morphology were recorded. All patients were observed for clinical and radiographic fusion achievement. Complications and hardware failure of the implant was also recorded. The preliminary results from our clinical experience have been positive. Six out of the 7 joints achieved full fusion. The elastic intramedullary implant is an alternative for finger arthrodesis that provides compression, stability, and adequate fusion. Using this technique, our patients regained a pain-free, stable, useful, and cosmetically acceptable hand.
手部手指关节的关节炎和不稳定会导致慢性疼痛和手部功能下降。对于此类患者，关节融合术是一种普遍接受的外科治疗方法。手部指间关节和拇指掌指关节的关节融合术有多种技术可供选择。我们介绍了7例使用髓内植入物（X-Fuse）进行指间关节和拇指掌指关节融合术患者的治疗经验。记录了手指稳定性、软组织刺激、感染率和指甲形态等临床参数。观察所有患者的临床和影像学融合情况。还记录了植入物的并发症和硬件故障。我们临床经验的初步结果是积极的。7个关节中有6个实现了完全融合。弹性髓内植入物是手指关节融合术的一种替代方法，可提供加压、稳定性和充分融合。采用这种技术，我们的患者恢复了无痛、稳定、有用且外观可接受的手部。
