This procedure has been widely performed to treat the fifth metacarpal neck fracture (FMNF) in adults. This study was performed to determine whether using AIMN with a single K-wire to treat FMNF in adolescents would have good clinical and radiographic outcomes.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>In this retrospective study, 21 children (aged 11\u201316 years) with FMNF were treated using AIMN with a single K-wire from May 2017 to January 2020 in our hospital. Indications for intervention were severe displacement with malrotation deformity, apex dorsal angulation of greater than 40\u00b0, or both. Collected data included apex dorsal angulation, range of motion (ROM) in the fifth metacarpophalangeal (MCP) joint, Visual Analog Scale (VAS) for pain, grip strength, and Disabilities of the Arm, Shoulder, and Hand (DASH) score.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>All patients were followed up for 12\u201324 months (average, 16.57 months), and all patients obtained anatomical reduction postoperatively. The healing time was 2.69\u2009\u00b1\u20090.83 months (range, 2\u20134 months). Average apex dorsal angulation was reduced significantly from 44.49\u00b0\u00b12.64\u00b0 to 15.74\u00b0\u00b12.47\u00b0 (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). The average ROM in the MCP joint and apex dorsal angulation of the injured side were not significantly different from those of the uninjured side. The average DASH score was 1.76\u2009\u00b1\u20091.48 (range, 0\u20134), the mean VAS was 0.19\u2009\u00b1\u20090.60 (range, 0\u20132), and the mean grip strength was 91.55\u2009%\u00b14.52\u2009% (range, 85\u2013101\u2009%). No secondary displacement, dysfunction, nonunion, infection, or osteonecrosis was observed during the follow-up.
