Abstract

Introduction: Fractures of the metacarpal and proximal phalanges are common injuries, accounting for a significant proportion of upper extremity fractures. Research into minimally invasive techniques that promote bone healing and facilitate early functional recovery is essential. Intramedullary headless compression screw fixation is a novel technique that has the potential to meet these criteria. Objectives: To evaluate bone union, functional recovery, and complications associated with intramedullary headless compression screw fixation in metacarpal and proximal phalangeal fractures. Materials and Methods: This was a prospective case series involving 20 patients (23 fractures) who underwent intramedullary headless screw fixation at Xuyen A Tay Ninh General Hospital from January to December 2024. All patients were followed for a minimum of 3 months. Outcomes assessed included clinical and radiographic union, total active motion (TAM), grip strength, visual analog scale (VAS) for pain, complications, and patient satisfaction. Results: All fractures achieved clinical and radiographic union after a mean of 5.3 ± 0.73 weeks. The average TAM was 254.7° ± 6.2°, with grip strength reaching 92.3% compared to the contralateral hand. All patients reported complete pain relief by 5 weeks postoperatively. Minor complications included 5° angular deformity (47.8%) and 2mm shortening (17.4%). No cases of extension loss, tendon-related complications, infection, screw loosening, or breakage were recorded. All patients expressed satisfaction with the treatment. Conclusion: Intramedullary headless compression screw fixation for metacarpal and proximal phalangeal fractures is a highly effective technique, achieving a 100% union rate, excellent functional recovery, and a low rate of complications
