Open Reduction and Internal Fixation with Mini-plate and Screws for Management of Unstable Metacarpal Fracture among Hand Injuries in a Tertiary Care Center: A Descriptive Cross-sectional Study

Abstract

Introduction: Hand injuries metacarpal fractures are common and it accounts about 14 to 28%. Mini-plate fixation in unstable metacarpal fractures provides absolute stability and early mobilization of fingers to reduce complications. The purpose of this study is to find out the prevalence of open reduction and internal fixation with mini-plate and screws for management of unstable metacarpal fracture among hand injuries done in a tertiary care center.

Methods: This was a descriptive cross-sectional study done from February 2019 and January 2021 in a tertiary care center with unstable isolated metacarpal fracture treated with mini-plate fixation and were followed up for six months duration. Ethical approval and informed written consent were taken from all patients. The outcome was assessed by the American Society for Surgery of the Hand Total Active Flexion Score. Convenient sampling method was used. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. Statistical Package for Social Sciences used for analysis.

Results: Out of 250 patients who underwent hand surgeries, open reduction and internal fixation with mini-plate and screws for unstable metacarpal fracture were done in 32 (12.8%) (8.66-16.94 at 95% Confidence Interval). The mean time of fracture union was 6.78±1.008 weeks. Functional outcome according to American Society for Surgery of the Hand Total Active Flexion score was excellent in 25 (78.2%), good in 6 (18.8%), and poor in 1 (3%) patient.

Conclusions: Fixation of metacarpal fracture by mini-plate and screws was required in fewer patients. Mini-plate fixation provides better stability and early mobilization for unstable metacarpal fractures to achieve a good functional outcome.
