Management of distal femoral type 33A fractures: Minimally invasive percutaneous osteosynthesis versus intramedullary fixation

Abstract

Background: Distal femur fractures, common across all age groups, are effectively treated with surgical interventions for faster recovery and mobility. Techniques like minimally invasive percutaneous osteosynthesis and retrograde intramedullary nailing provide good outcomes with fewer complications. Aim of work: To evaluate of clinical, function and radiographic outcomes of treating distal femoral fractures (AO type 33A) by minimally invasive percutaneous osteosynthesis versus intramedullary fixation. Methods: A prospective intervention study including 20 skeletally mature patients with closed or Gustilo type I/II open distal femoral fractures (type 33A), divided into two groups: Group A (treated with minimally invasive percutaneous osteosynthesis) and Group B (treated with intramedullary nailing). Results: The intramedullary fixation had better operative time, quicker union, and better WOMAC and Lysholm scores than minimally invasive percutaneous osteosynthesis however, complications were similar in both groups. Conclusions: The approved results of this study were obtained using both methods and compared with the findings of prior research. Nevertheless, our research demonstrated a superior union rate and reduced surgical morbidities associated with the nail.
