【 摘 要 】

PurposeTo evaluate the efficacy of a modified internal fixation method for the treatment of fifth metacarpal neck fracture.MethodsFrom March 2018 to December 2019, 12 patients with the fifth metacarpal neck fractures of the hands were treated with the Kirschner wires and locking plate internal fixation method. Each patient’s gender, age, dominant hand, injured hand, trauma mechanism, preoperative and postoperative deformity (angulation and the length of the fifth metacarpal), the range of motion of the metacarpophalangeal joint and grip strength of each side, the time of return to work, and follow-up time were recorded and calculated.ResultsThe mean follow-up time was 16.8 months, and the angulations of preoperative and postoperative deformity were 40.0 ± 3.7°and 17.6 ± 1.7°, respectively. The length of the fifth metacarpals of preoperative and postoperative deformity were 51.5 ± 2.1 mm and 60.0 ± 1.8 mm, respectively. At the last follow-up, the range of motion of the fifth metacarpophalangeal joint of the injured side and the contralateral side were 84.3 ± 3.6°and 86.5 ± 2.0°, and the grip strength of the injured side and the contralateral side were 74.8 ± 6.1 LB and 78.6 ± 8.3 LB, respectively, without statistically significant differences. QDASH score was 2.0 ± 1.0, and the time of return to work was 6.0 ± 0.7 weeks.ConclusionThe modified internal fixation method is one of the alternative treatments for the fifth metacarpal neck fracture with good curative effects.
