Objective: To study the clinical and radiological outcomes of patients with extra-articular phalangeal and metacarpal fractures who were treated with minimally invasive internal fixation using retrograde intramedullary compression screws. Materials and Methods: Prospective study in patients over 18 years of age treated for simple, transverse or short oblique, extra-articular phalangeal and metacarpal fractures between November 2016 and June 2019. The series included 47 patients and 76 fractures: 28 metacarpal bones (MC), 27 proximal phalanges (PP), 21 middle phalanges (MP). Clinical and functional outcomes were assessed with goniometry, documenting the total active range of motion (TAM). Radiological outcomes were assessed using the criteria proposed by Pun et al. All patients completed the Quick DASH questionnaire at last follow-up. Results: The average follow-up period was 24.5 months. All study fractures average TAM was 238°, metacarpal TAM was 252°, and phalangeal TAM was 230°. Radiograph evaluation showed fracture consolidation in all cases. Average time taken to return to normal daily activities was 79 days. Average final Quick DASH score was 4.5. There were no complications nor secondary surgeries. Conclusions: Minimally invasive internal fixation with retrograde intramedullary compression screw proved to be a highly effective option in the treatment of extra-articular phalangeal and metacarpal fractures.
