Dfo Distal Femoral Osteotomy
This entails two tiny cuts on the entrance of the knee, one for the digicam and one for the instruments. This allows us to establish and deal with any meniscal tears or free flaps of articular cartilage. Occasionally a affected person who has had osteotomy surgery will go on to develop osteoarthritis throughout the knee or just suffers with extreme ache.
The diaphyseal midline was marked with an electrocautery and a Codman pen to keep away from angular deviation during the stabilization of the plaque. The wedge guidewire was positioned with the angular reduce predefined for every case, and ∼ seventy five% of the wedge was sectioned and removed; this was thought of a partial procedure. The osteotomy was checked with radioscopy and stabilized with an angled blade plaque at ninety° in older instances or locked with proximal and distal screws in the latest ones (Fig. 1). The ideal diploma of correction in circumstances of varus malalignment has been intensively mentioned over a few years.

Advantages of the medial closing-wedge technique are direct bone apposition leading to inherent stability of the construct, as well as reliable bony healing, and fewer hardware irritation. Advantages of the lateral opening-wedge technique are a single bony cut and subsequently more of a capability to adjust correction intraoperatively. However, this technique requires bone grafting and has a high price of hardware irritation or removal. We current a surgical method for the medial closing-wedge distal femoral osteotomy using an anteromedial-distal femoral locking plate. In sufferers presenting with lateral-based knee ache, an in depth historical past is obtained and physical examination carried out. Imaging begins with 4-view knee radiographs in addition to standing full-size alignment radiographs .
Distal femoral osteotomy is indicated to right deformities and malalignments similar to valgus knee, a deformity the place the knee angles out from the center of the physique. It is also carried out to treat osteoarthritis in young lively sufferers contraindicated for joint replacement. Several HTO studies agree with a ± 3° deviation from planning as a suitable range . Reported results are very variable with 23 to 92% being in the defined target vary .
Other than concurrently either including bone or taking out bone, there is probably not a big difference between both approach. The most important approach, due to this fact, could be the one that one’s surgeon feels most comfy with performing a distal femoral osteotomy. For patients with ACL deficiencies, if they’ve important arthritis of their lateral compartment with valgus alignment, then a concurrent ACL reconstruction with a distal femoral osteotomy could also be indicated. In addition, there are some sufferers who might have a cartilage replacement surgery and/or a lateral meniscal transplant with their ACL reconstructions. The next most typical indication for a distal femoral osteotomy is when a patient is knock knee and desires a lateral meniscal transplant and/or a cartilage resurfacing procedure of the surface compartment of their knee.
The vastus lateralis is carefully lifted up from intermuscular septum and the distal medial facet of the femoral shaft is recognized. This is an essential step in the publicity as significant bleeding may be encountered if not appropriately coagulated, which may trigger vital problems to the limb, as well as affect visualization in the course of the process. The authors’ most popular technique for a distal femoral opening-wedge osteotomy is described under with an accompanying video demonstration . Distal femoral development plate fractures are not benign fractures and shouldn’t be handled as such. Patients and their families ought to be educated and warned concerning the potentialities of complications, which are not restricted to development disturbance alone.

At six months observe-up, bony fusion was achived and %MA was forty eight.5% from the medial fringe of the tibial plateau. Bony fusion is achieved and %MA is forty eight.5% from the medial fringe of the tibial plateau. Valgus deformity has improved in appearance, whereas decrease limb length discrepancy improved to -0.5 cm in the left decrease limb and the range of motion of the best knee also improved to 0 to 150 degrees .
Therefore, the objective of the distal femoral osteotomy is to shift the affected person from being valgus in the direction of being varus. Oftentimes, we are going to place the patient right into a lateral compartment unloader brace to use as a display screen to find out that a distal femoral osteotomy could also be a helpful process. We have discovered that patients who’ve good ache aid with the usage of a lateral unloader brace often have equally good or higher ache aid after a distal femoral osteotomy realignment procedure.
Dissection is taken down through the interval between the vastus medialis oblique and the intermuscular septum, exposing the medial cortex of the femur. The osteotomy website is marked with K-wires primarily based on preoperative templating. Proximal and distal osteotomy cuts are made with care taken not to cut or fracture the lateral cortex, and the osteotomy is gently closed. An anteromedial-distal medial femur locking plate is placed and confirmed to be in the correct position using intraoperative fluoroscopy. Video 1 Distal femoral medial closing-wedge osteotomy on the proper distal femur of a cadaveric specimen. Fractures of the distal femoral growth plate are exceptional in that they’re the third commonest progress plate fracture in youngsters , but they carry a risk of growth disturbance in up to 90% of circumstances .
