Description
Summary:The moment arm of gluteus medius proportionated to distance from femoral head tends to be decreased postoperatively in valgus-impacted femoral neck fractures treated by in situ internal fixation. The aim of this article is to introduce a new gentle technique to correct the deformity. The innovative technique of Minimally Invasive Closed Reduction for Impacted Femoral neck fractures (MICRIF) mainly focused to disimpact valgus neck fractures into anatomical position. Patients were positioned on the fracture table to fix the hip joint in abduction and internal rotation. A 2.4-mm diameter Kirschner wire was inserted a few centimetres outside the iliac crest piercing the acetabular beak to enter the femoral head, followed by repositioning of the lower extremity from abduction into neutral. This method provides satisfactory anatomical reduction. Thereafter, a surgical implant was applied to osteosynthesize the reduced fracture. This simple technique effectively provides anatomical reduction in valgus impacted femoral neck fracture.
