Osteosynthesis with Retrograde Cannulated Screws for Cervico/Diaphyseal Fractures of Central Metatarsals: A Treatment Alternative

Research Type: Level 4 – Case series Introduction/Purpose: Fractures of the central metatarsals are common, and their treatment can be complex. Our objective is to evaluate the effectiveness of intramedullary screw fixation in these fractures by describing the surgical technique and patient follow-up Methods: In this prospective case series, 16 patients with fractures of the central metatarsals were treated, of which 12 met the inclusion criteria and were surgically treated with intramedullary screws. The follow-up period was 12 months. The quality of the radiographic reduction, bone healing, and functional outcomes were evaluated using the AOFAS scale. Results: The quality of fracture reduction was anatomical in 11 cases (83%) and good in 2 cases (17%). All patients, except one, showed bone healing at 8 weeks post-surgery. The average AOFAS score was 86.2 (Range: 71 to 94). Two complications were recorded: one superficial surgical site infection and one delayed union (17%). Conclusion: This pioneering study demonstrates the feasibility of internal fixation with retrograde intramedullary screws to treat cervico/diaphyseal fractures of central metatarsals as an alternative, especially in short oblique or transverse fractures, with encouraging initial results.
