Distal Femoral Osteotomy Seattle, Wa
In this article, we describe our most popular operative technique for a lateral opening wedge varus-producing distal femoral osteotomy to correct delicate to average valgus malalignment. Video 1 The video describes our most popular technique for lateral opening wedge distal femoral osteotomy. PearlsRadiolucent retractors enable fluoroscopic visualization while the osteotomy is carried out.The surgeon ought to mark the noticed 5-10 mm shorter than the length of the wire to avoid plunging and violating the lateral cortex. Two separate marks may be used to correspond to the lengths of the anterior and posterior wires, respectively.Gentle and/or slow closing of the osteotomy hole should be carried out to avoid fracture of the lateral cortex.
Through applicable indication and patient selection, each kinds of valgisation osteotomies close to the knee joint can present enhancements in medical perform, ache stage and high quality of life. These joint-preserving interventions thus symbolize a useful remedy option in varus deformities. Varus deformities of the knee are frequently corrected by osteotomies, which ought to be carried out at the stage of origin. But in distinction to excessive tibial osteotomies , little data exists for distal femoral osteotomies . An Osteotomy is a managed surgical break or fracture of the bone to permit realignment of the limb.
Femoral Distal Opening And Closing Wedge Osteotomy :
Diagnostic arthroscopy can be utilized to evaluate for associated meniscoligamentous or cartilage injuries for concomitant procedures with the osteotomy. The denoted buildings characterize the lateral femoral condyle , the lateral meniscus , and the lateral tibial plateau . The goal of surgical procedure is to re-create impartial alignment, such that the mechanical axis line passes by way of the center of the knee.3 The quantity of correction is calculated based on the angle formed between the mechanical axis of the femur and tibia . Practically, 5 degrees of malalignment is the brink to consider osteotomy.
