PURPOSE
To compare the functional outcome of distal fixation on the second metacarpal versus the third metacarpal in patients treated with dorsal bridge plating for comminuted intra-articular distal radius fractures.
MATERIALS AND METHODS
The functional outcome of 60 patients treated with dorsal bridge plating was assessed 6 months postoperatively comparing distal fixation on the second metacarpal versus the third metacarpal. Pain, ability to work post-fixation, range of movements, stiffness, and grip strength were the parameters assessed.
RESULTS
Distal fixation on the third metacarpal resulted in more stiffness and risk of tendon entrapment of the first and third extensor compartments when compared to distal fixation on the second metacarpal.
CONCLUSION
Dorsal bridge plating with a distal fixation on the second metacarpal shower better functional outcome compared to the third metacarpal with a better range of movements, less risk of tendon entrapment, and better fracture stabilization.
目的
比较在采用背侧桥接钢板治疗桡骨远端粉碎性关节内骨折的患者中，将钢板远端固定于第二掌骨与第三掌骨的功能结果。
材料与方法
对60例采用背侧桥接钢板治疗的患者在术后6个月进行评估，比较钢板远端固定于第二掌骨与第三掌骨的情况。评估的参数包括疼痛、固定后工作能力、活动范围、僵硬程度和握力。
结果
与将钢板远端固定于第二掌骨相比，将钢板远端固定于第三掌骨会导致更多的僵硬，以及第一和第三伸肌间隔出现肌腱卡压的风险。
结论
与将钢板远端固定于第三掌骨相比，将钢板远端固定于第二掌骨的背侧桥接钢板治疗具有更好的功能结果，活动范围更大，肌腱卡压风险更低，骨折稳定性更好。
