Functional Outcomes of Intramedullary Screw Fixation for Diaphyseal Fractures of Metacarpals and Proximal Phalanges: A Prospective Observational Study

Background: Hand fractures involving metacarpals and phalanges account for 20-30% of all fractures. Intramedullary screw fixation has emerged as a minimally invasive option offering angular stability and early mobilization potential. Objective: To evaluate functional outcomes of intramedullary screw fixation for diaphyseal metacarpal fractures using Total Active Motion (TAM), Quick DASH (qDASH), and Rust scores, and identify factors influencing recovery. Methods: This prospective observational study included 30 patients with 47 diaphyseal metacarpal fractures treated at SMS Medical College, Jaipur. Outcomes were assessed at 4 weeks, 2 months, and 3 months using TAM score (excellent ?220°, good 180-219°, fair 140-179°, poor
