To assess objective and subjective outcomes of distal interphalangeal joint arthrodesis with a headless compression screw for degenerative osteoarthritis.
We retrospectively analyzed 102 cases of distal interphalangeal joint arthrodesis performed with headless compression screws on 59 patients. We included only primary cases of degenerative osteoarthritis with a minimum follow-up of 7 months. We identified appropriate bone coaptation and hardware positioning on postoperative radiographs in all digits. The mean follow-up period was 26 months (range, 7-67 mo).
In 89 of 102 cases, patients were fully satisfied; in 9 cases, they were satisfied. Four complications occurred: 2 cases of prominent hardware, 1 complex regional pain syndrome type 1, and 1 symptomatic bony callus on the fused joint. Secondary surgery was required in each of these 4 cases. No nonunion, malunion, nail dystrophy, pseudarthrosis, or infection occurred. All arthrodeses healed.
Distal interphalangeal joint arthrodesis with headless compression screws was shown to be safe and effective in cases of degenerative osteoarthritis, with a low complication rate.
评估无头加压螺钉用于指间关节融合术治疗退行性骨关节炎的客观和主观疗效。
我们回顾性分析了59例患者采用无头加压螺钉进行的102例指间关节融合术。仅纳入退行性骨关节炎的原发性病例，且随访时间最短为7个月。我们在术后X线片上确定了所有手指的适当骨对接和内固定位置。平均随访时间为26个月（范围7 - 67个月）。
102例患者中，89例完全满意，9例满意。发生了4例并发症：2例内固定物突出，1例1型复杂性区域疼痛综合征，1例融合关节处出现有症状的骨痂。这4例均需二次手术。未发生骨不连、畸形愈合、甲营养不良、假关节或感染。所有关节融合均愈合。
无头加压螺钉用于指间关节融合术治疗退行性骨关节炎显示出安全有效，并发症发生率低。
