Distal Femoral Osteotomy Seattle, Wa

Distal Femoral Osteotomy Seattle, Wa

Several authors have identified a postoperative HKA of 3–5° valgus or a mechanical axis at 62–66% of the tibial width as optimum in medial OA . Recently research consider the extent of medial chondromalacia and perform an individually adjusted correction with a more reasonable targeted range of valgus (HKA 1.7–5° or 50–65% of the whole tibial plateau width), whereas avoiding overcorrection . A knee joint arthroscopy is recommended in the same session, for addressing intraoperative pathologies and nice-tuning of correction, depending on the sort and extent of intraarticular damage .

distal femoral osteotomy

Through acceptable indication and patient selection, each kinds of valgisation osteotomies near the knee joint can present enhancements in medical perform, ache degree and high quality of life. These joint-preserving interventions thus represent a useful therapy possibility in varus deformities. Varus deformities of the knee are incessantly corrected by osteotomies, which should be carried out at the degree of origin. But in contrast to high tibial osteotomies , little data exists for distal femoral osteotomies . An Osteotomy is a controlled surgical break or fracture of the bone to allow realignment of the limb.

Dfo (distal Femoral Osteotomy)

Diagnostic arthroscopy can be used to evaluate for associated meniscoligamentous or cartilage accidents for concomitant procedures with the osteotomy. The denoted structures symbolize 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 via the center of the knee.3 The quantity of correction is calculated based mostly on the angle fashioned between the mechanical axis of the femur and tibia . Practically, 5 levels of malalignment is the brink to contemplate osteotomy.

  • The approach offered on this article offers a safe, reproducible technique 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 website based on the preoperative plan.
  • The diaphyseal midline was marked with an electrocautery and a Codman pen to avoid angular deviation during the stabilization of the plaque.

Sports-associated accidents and motorcar accidents are currently the commonest causes of harm. Proper care of these injuries includes counseling sufferers and fogeys concerning the long run likelihood of growth-associated problems. Among them, Salter-Harris sort II is the commonest, making up about half of progress plate fractures, whereas sorts IV and V are rare, accounting for only a few % . Distal femoral perichondral ring injury (SH type VI, Rang’s sort VI) is a comparatively uncommon damage and is known to result in a excessive prevalence of development disorders with angular deformity . However, the timing of treatment and approaches to treatment have but to be established.
