A Single Intramedullary K-Wire Is Sufficient for theManagement of Nonthumb Metacarpal Shaft Fractures

'is study aims to evaluate the outcome after the internal fixation of diaphyseal metacarpal fractures by a singleintramedullary K-wire.Methods. In this prospective case series study, conducted from July 2017 to June 2019 in 23 adult patientswith a single, unstable, diaphyseal metacarpal fracture, outcomes after internal surgical fixation using a single antegradeintramedullary K-wire were evaluated. 'e outcomes were evaluated by unio‎n rate, time to unio‎n, handgrip measurements at 6and 12 months, and the modified Disabilities of the Arm, Shoulder, and Hand (DASH) score at 12 months.Results.'e studypopulation consisted of 17 males and 6 females, with a mean patient age of 28.4±8.5 years (range, 16–45 years). 'e median timeto final follow-up was 14±1.8 months (range: 12–24 months). 'e mean duration of the unio‎n was 7.3±1.6 weeks (range: 5–11weeks), with a unio‎n rate of 95.7% (22 cases). 'e mean handgrip strength was 68%±12.8% of the strength of the uninjured handafter 6 months and 92.7%±6.9% after 12 months. 'e mean modified DASH score was 2.6±0.26 after 12 months (range: 0–5.8).'ere were no cases of malrotation or infection. In conclusion, using a single 1.8–2.0 mm K-wire gives excellent functionaloutcomes and unio‎n rate without significant complications when used to treat an unstable metacarpal shaft fracture.
