There is no robust evidence for the best treatment practice for metacarpal neck fractures. The purpose of this comparative study was to investigate whether the intramedullary nail or low-profile plate allows for good clinical and radiological results for displaced metacarpal neck fractures.
We prospectively reviewed 30 patients with a displaced metacarpal neck fracture who underwent surgery: 15 with intramedullary nails and 15 with low-profile plates. Radiographic and clinical outcomes of both groups were compared. Objective findings of range of finger motion and grip strength were assessed at 3, 6, and 12 months postoperatively.
There was no non-union, and postoperative complications included extensor tendon rupture in one and transient ulnar nerve neuritis in two. Radiological parameters after the fracture healing were comparable between the two groups. Postoperative range of finger motion was better in patients with the intramedullary nail, and acquired grip strength in the low-profile plate group was superior to that in the intramedullary nail group.
The current results indicate that both procedures are highly effective in maintaining fracture restorations. Plate fixation provides earlier recovery of powerful hand function, and intramedullary nailing allows a wide range of finger motion.
对于掌骨颈骨折的最佳治疗方法,目前尚无确凿证据。本比较研究的目的是调查髓内钉或低轮廓钢板治疗移位掌骨颈骨折是否能取得良好的临床和影像学效果。
我们前瞻性地回顾了30例接受手术治疗的移位掌骨颈骨折患者:15例采用髓内钉治疗,15例采用低轮廓钢板治疗。比较两组的影像学和临床结果。在术后3个月、6个月和12个月评估手指活动范围和握力的客观指标。
未发生骨不连,术后并发症包括1例伸肌腱断裂和2例短暂性尺神经神经炎。两组骨折愈合后的影像学参数相当。髓内钉治疗患者术后手指活动范围更佳,低轮廓钢板组获得的握力优于髓内钉组。
目前的结果表明,两种手术方法在维持骨折复位方面都非常有效。钢板固定能使手部强大功能更早恢复,而髓内钉固定可使手指活动范围更广。
