Distal Femoral Osteotomy Seattle, Wa
In this article, we describe our most well-liked operative approach for a lateral opening wedge varus-producing distal femoral osteotomy to appropriate delicate to moderate valgus malalignment. Video 1 The video describes our preferred technique for lateral opening wedge distal femoral osteotomy. PearlsRadiolucent retractors permit fluoroscopic visualization whereas the osteotomy is carried out.The surgeon ought to mark the saw 5-10 mm shorter than the size of the wire to avoid plunging and violating the lateral cortex. Two separate marks could also be used to correspond to the lengths of the anterior and posterior wires, respectively.Gentle and/or slow closing of the osteotomy gap ought to be carried out to avoid fracture of the lateral cortex.
Through applicable indication and affected person selection, both sorts of valgisation osteotomies close to the knee joint can present enhancements in clinical operate, pain level and high quality of life. These joint-preserving interventions thus characterize a priceless remedy choice in varus deformities. Varus deformities of the knee are incessantly corrected by osteotomies, which ought to be carried out at the level of origin. But in contrast to excessive tibial osteotomies , little data exists for distal femoral osteotomies . An Osteotomy is a controlled surgical break or fracture of the bone to permit realignment of the limb.
Femoral Distal Opening And Closing Wedge Osteotomy :
Diagnostic arthroscopy can be used to assess for related meniscoligamentous or cartilage accidents for concomitant procedures with the osteotomy. The denoted buildings represent the lateral femoral condyle , the lateral meniscus , and the lateral tibial plateau . The objective of surgery is to re-create neutral alignment, such that the mechanical axis line passes through the center of the knee.three The amount of correction is calculated primarily based on the angle fashioned between the mechanical axis of the femur and tibia . Practically, 5 levels of malalignment is the edge to think about osteotomy.
- There were no related differences in hospital keep, blood loss or surgery time.
- The technique presented on this article supplies a secure, reproducible methodology to perform the medial closing-wedge DFO.
- Corticocancellous wedges are harvested from the femoral neck portion of an allograft femoral head and positioned into the osteotomy web site in accordance with the preoperative plan.
- Among them, Salter-Harris kind II is the most typical, making up about half of growth plate fractures, whereas varieties IV and V are rare, accounting for only some % .
- The diaphyseal midline was marked with an electrocautery and a Codman pen to keep away from angular deviation in the course of the stabilization of the plaque.
Bone fusion is achieved and %MA is forty eight.5% from the medial edge of the tibial plateau. Severe valgus deformity is noted with an FTA of 160 levels and a %MA of a hundred% from the medial fringe of the tibial plateau. Limitations of this study are the heterogeneous study population and the low case number for femoral and tibial osteotomies. The anticipated variety of cases within this cohort and the imply values and commonplace deviations in accuracy and clinical consequence parameters in previous research had been too small for a prospective energy analysis. Additionally, long-time period details about scientific operate or survival rates is lacking. Several authors report an improvement of scientific scores for up to 5 years postoperatively after HTO.
