Metacarpal Fracture Repair: Early Reoperation Rates and Characteristics.

Purpose: Metacarpal fractures are common injuries of the hand that often require operative repair. However, there is a paucity of data regarding the rate of reoperation and circumstances following metacarpal repair. Methods: A retrospective review of all metacarpal fracture cases performed at a single academic institution between 2017 and 2021 was performed. All patients with isolated, acute metacarpal fractures were included for review. Data on patient demographics, fracture morphology, surgical technique, rate of early reoperation, and reason for reoperation were collected. Results: A total of 499 patients were identified to have undergone operative treatment for an isolated metacarpal fracture with an average follow-up of 4.2 months. The rate of unplanned early reoperation was 8.0% (n = 40), with seven patients requiring revision fracture surgery and 33 patients undergoing removal of symptomatic hardware. Mean and median time to reoperation was 2.1 and 1.5 months, respectively. The rate of reoperation for fractures of the metacarpal shaft was significantly lower than that of other fracture locations. Among the 40 revision cases, one case was following percutaneous fixation while 39 cases were following open reduction and internal fixation. Other demographic factures and fracture characteristics failed to show significant correlations to the rate of reoperation. Conclusions: An unplanned early reoperation rate of 8.0% after operative fixation of acute metacarpal fractures was observed with the majority involving cases of removal of symptomatic hardware and an average time to reoperation of approximately 2.1 months. This information can be used to counsel patients and set expectations about the potential for metacarpal fracture surgeries. Type of Study/Level of Evidence: Prognosis 2b.
