Distal Femoral Osteotomy

Distal Femoral Osteotomy

In this text, we describe our most well-liked operative approach for a lateral opening wedge varus-producing distal femoral osteotomy to correct gentle to reasonable valgus malalignment. Video 1 The video describes our preferred method for lateral opening wedge distal femoral osteotomy. PearlsRadiolucent retractors permit fluoroscopic visualization whereas the osteotomy is performed.The surgeon ought to mark the noticed 5-10 mm shorter than the size of the wire to keep away from 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 hole should be carried out to avoid fracture of the lateral cortex.

distal femoral osteotomy

Through applicable indication and patient selection, both sorts of valgisation osteotomies near the knee joint can provide improvements in scientific perform, pain degree and high quality of life. These joint-preserving interventions thus represent a priceless therapy option in varus deformities. Varus deformities of the knee are frequently corrected by osteotomies, which should be carried out at the degree of origin. But in distinction 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.

Dfo (distal Femoral Osteotomy)

Diagnostic arthroscopy can be utilized to assess for related meniscoligamentous or cartilage accidents for concomitant procedures with the osteotomy. The denoted constructions 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 through the center of the knee.3 The amount of correction is calculated based on the angle shaped between the mechanical axis of the femur and tibia . Practically, 5 levels of malalignment is the brink to contemplate osteotomy.

  • There had been no relevant variations in hospital stay, blood loss or surgical procedure time.
  • The method presented in 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 sort II is the most common, making up about half of development plate fractures, whereas varieties IV and V are rare, accounting for just a few p.c .
  • 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.

Sports-associated injuries and motorized vehicle accidents are at present the most common causes of harm. Proper care of these injuries includes counseling sufferers and oldsters regarding the future chance of development-associated problems. Among them, Salter-Harris sort II is the commonest, making up about half of growth plate fractures, whereas varieties IV and V are uncommon, accounting for only some percent . Distal femoral perichondral ring injury (SH type VI, Rang’s type VI) is a relatively uncommon injury and is thought to lead to a high prevalence of progress issues with angular deformity . However, the timing of therapy and approaches to treatment have yet to be established.
