    Abstract:
    OBJECTIVE: This retrospective study compared two minimally invasive surgical methods for fifth metacarpal neck fractures in adolescents: percutaneous Kirschner wire (K-wire) fixation and elastic stable intramedullary nailing (ESIN). METHODS: This study involved 42 adolescents aged 11 to 16 years with fifth metacarpal neck fractures treated by either K-wire fixation (n = 20) or ESIN (n = 22). The palmar tilt angle and shortening were compared on radiographs preoperatively and 6 months postoperatively. Total active range of motion (TAM), the visual analogue scale score for pain, and the Disabilities of the Arm, Shoulder and Hand score for upper limb function were recorded at 5 weeks, 3 months, and 6 months postoperatively. RESULTS: The mean TAM was significantly greater in the ESIN than K-wire group at all postoperative time points. The mean external fixation time was 2 weeks longer in the K-wire than ESIN group. One patient in the K-wire group developed infection. There was no statistically significant difference between the two groups in other postoperative outcomes. CONCLUSIONS: ESIN fixation has the advantages of greater stability, better activity, a shorter external fixation time, and a lower infection rate than K-wire fixation in the treatment of fifth metacarpal neck fractures in adolescents.
