Distal Femoral Osteotomy Seattle, Wa

In this article, we describe our most well-liked operative method for a lateral opening wedge varus-producing distal femoral osteotomy to right mild to moderate valgus malalignment. Video 1 The video describes our preferred approach for lateral opening wedge distal femoral osteotomy. PearlsRadiolucent retractors allow fluoroscopic visualization while the osteotomy is carried out.The surgeon should mark the noticed 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 sluggish closing of the osteotomy hole ought to be performed to keep away from fracture of the lateral cortex.

distal femoral osteotomy

Through appropriate indication and patient selection, both sorts of valgisation osteotomies close to the knee joint can present improvements in medical operate, ache level and high quality of life. These joint-preserving interventions thus characterize a useful remedy choice in varus deformities. Varus deformities of the knee are frequently corrected by osteotomies, which must be performed on the degree of origin. But in contrast to high tibial osteotomies , little knowledge 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 :

In the case of lateral compartment osteoarthritis we carry out an osteotomy in the femur to realign the knock knee to being extra straight or even slightly bow legged. Patients with lateral compartment arthritis normally complain of pain and stiffness around the knee. They often level to the outer side of the knee as the primary focus of their pain. The knee can swell up notably after strenuous exercise and some patients will observe grinding or locking of their knee. Depending upon the diploma of severity of the symptoms they could have issue doing their usual sporting activities corresponding to running, or strolling as far as normal. In general, sufferers who wish to remain relatively excessive impact, especially laborers or sufferers who are still fairly lively, or in younger patients, a distal femoral osteotomy would be most popular over a total knee substitute.

  • This article supplies a detailed, step-sensible methodology that permits the reproducible creation of a medial closing-wedge DFO for the valgus knee utilizing locking-plate fixation.
  • Typically, a more lateral pores and skin incision is made to gain entry to the lateral femoral cortex.
  • Closure is then completed in layers with the medial patellofemoral ligament repaired if partially transected.
  • Commonly, genu valgum occurs because of femoral malalignment and should be corrected with a DFO, whereas genu varum happens due to tibial malalignment and should be corrected with an HTO.
  • The TomoFix medial distal femur anatomical plate was bent based on the individual’s anatomy and positioned underneath the vastus medialis muscle for osteotomy fixation .

Bone fusion is achieved and %MA is 48.5% from the medial fringe of the tibial plateau. Severe valgus deformity is famous with an FTA of one hundred sixty degrees and a %MA of 100% from the medial fringe of the tibial plateau. Limitations of this examine are the heterogeneous examine inhabitants and the low case quantity for femoral and tibial osteotomies. The expected variety of instances within this cohort and the imply values and normal deviations in accuracy and scientific outcome parameters in previous studies had been too small for a potential power analysis. Additionally, long-time period details about medical perform or survival rates is lacking. Several authors report an enchancment of medical scores for up to 5 years postoperatively after HTO.
