distal femoral osteotomy

Distal Femoral Osteotomy

Several authors have identified a postoperative HKA of 3–5° valgus or a mechanical axis at sixty two–66% of the tibial width as optimum in medial OA . Recently studies think about the extent of medial chondromalacia and carry out an individually adjusted correction with a more reasonable focused vary of valgus (HKA 1.7–5° or 50–sixty five% of the entire tibial plateau width), while avoiding overcorrection . A knee joint arthroscopy is beneficial in the identical session, for addressing intraoperative pathologies and fine-tuning of correction, depending on the sort and extent of intraarticular injury .

Through acceptable indication and patient choice, both kinds of valgisation osteotomies near the knee joint can present enhancements in scientific operate, ache level and high quality of life. These joint-preserving interventions thus symbolize a valuable therapy choice in varus deformities. Varus deformities of the knee are regularly corrected by osteotomies, which must be carried out at the stage of origin. But in contrast to high tibial osteotomies , little knowledge exists for distal femoral osteotomies . An Osteotomy is a managed surgical break or fracture of the bone to permit realignment of the limb.

Dfo (distal Femoral Osteotomy)

Diagnostic arthroscopy can be used to assess for related meniscoligamentous or cartilage injuries for concomitant procedures with the osteotomy. The denoted structures represent 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 via the center of the knee.3 The quantity of correction is calculated primarily based on the angle shaped between the mechanical axis of the femur and tibia . Practically, 5 levels of malalignment is the brink to consider osteotomy.

  • This article supplies a detailed, step-sensible method that allows the reproducible creation of a medial closing-wedge DFO for the valgus knee using locking-plate fixation.
  • Typically, a extra lateral skin incision is made to realize access to the lateral femoral cortex.
  • Closure is then accomplished in layers with the medial patellofemoral ligament repaired if partially transected.
  • 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 .

Sports-associated injuries and motor vehicle accidents are presently the commonest causes of harm. Proper care of these injuries contains counseling patients and fogeys concerning the future probability of growth-associated complications. Among them, Salter-Harris kind II is the commonest, making up about half of growth plate fractures, whereas sorts IV and V are rare, accounting for only a few p.c . Distal femoral perichondral ring damage (SH type VI, Rang’s sort VI) is a comparatively uncommon damage and is understood to lead to a high prevalence of progress problems with angular deformity . However, the timing of therapy and approaches to therapy have yet to be established.
