UNLABELLED
We report clinical outcomes in 12 patients with hemi-hamate replacement arthroplasty combined with volar plate arthroplasty. The volar plate was reattached using trans-osseous sutures to reconstruct the ligament-box complex after hamate grafting to augment the stability of the proximal interphalangeal joint. Ten patients had improved joint movement from a mean of 14° before surgery to a mean of 77° at a minimum follow-up of 2 years. Grip strength and pain of the affected hand and patient-rated hand and wrist scores were improved in these 10 patients. Two patients had poor results. One patient developed ankylosis, and one patient had resorption of the grafted bone. We conclude that the augmented hamate replacement arthroplasty is useful in treating chronic proximal interphalangeal joint fracture-dislocations.

我们报告了12例采用半钩骨置换关节成形术联合掌侧板关节成形术的临床结果。在植入钩骨后，通过穿骨缝线重新附着掌侧板以重建韧带盒复合体，以增强近端指间关节的稳定性。10例患者的关节活动度从术前平均14°改善至至少随访2年时的平均77°。这10例患者患手的握力、疼痛以及患者自评的手和腕部评分均得到改善。2例患者效果不佳。1例患者出现关节强直，1例患者出现移植骨吸收。我们得出结论，增强型钩骨置换关节成形术在治疗慢性近端指间关节骨折脱位方面是有效的。
