Dynamic condylar screw for subtrochanteric femur fractures with greater trochanteric extension.
Sixteen cases of subtrochanteric femur fractures with greater trochanteric extension were treated using the AO dynamic condylar screw (DCS). All cases were treated using the principles of strict indirect reduction to achieve anatomic alignment rather than anatomic reduction, with no bone grafting, and delayed weight bearing. The overall union rate was 93.7% (15 of 16). One unique case of implant failure with varus nonunion was encountered following repeat trauma. The advantages of the implant and technique are a simplified procedure, shorter operative time, and rapid union. Using the DCS with the indirect reduction method and delayed weight bearing is an acceptable choice in subtrochanteric femur fractures with greater trochanteric involvement when other adequate implants are not available for stable fixation.
