The purpose of our study is to retrospectively compare the use of tension band (TB) wiring and dorsal plating (DP) for the fixation of fifth metacarpal (MC) neck fractures. A retrospective study of patients who had surgical treatment of 5th MC fractures from 2009 to 2013 was performed. Data including patient demographics, mechanism of injury, pre and postoperative pain score, range of motion (ROM), duration of follow-up and whether implants were removed were documented. Three radiological parameters: angulation (in degrees), radial-ulnar displacement (in millimetres) and MC height ratio were measured. There were a total of 84 patients with isolated closed 5th MC neck fractures, of which 41 underwent DP and 43 underwent TB. Patients who underwent DP demonstrated better improvement in fracture angulation, radial-ulnar displacement, MC height ratio and final ROM compared to those who underwent TB. This study has shown that DP is a viable surgical treatment option for 5th MC neck fractures.
我们研究的目的是回顾性比较张力带（TB）钢丝内固定术和背侧钢板（DP）内固定术治疗第五掌骨（MC）颈骨折的效果。对2009年至2013年接受手术治疗第五掌骨骨折的患者进行了回顾性研究。记录的数据包括患者人口统计学资料、损伤机制、术前和术后疼痛评分、活动范围（ROM）、随访时间以及植入物是否取出。测量了三个放射学参数：成角（度数）、桡尺侧移位（毫米）和掌骨高度比。共有84例孤立性闭合性第五掌骨颈骨折患者，其中41例行背侧钢板内固定术，43例行张力带钢丝内固定术。与接受张力带钢丝内固定术的患者相比，接受背侧钢板内固定术的患者在骨折成角、桡尺侧移位、掌骨高度比和最终活动范围方面有更好的改善。本研究表明，背侧钢板内固定术是治疗第五掌骨颈骨折可行的手术治疗选择。
