Dfo Distal Femoral Osteotomy
After that we make a 10cm incision over the within facet of the leg simply above the knee to allow us to carry out a controlled osteotomy of the end a part of the femur. The complete leg alignment X rays allow us to accurately calculate exactly what size wedge of bone to remove in order to realign the limb. Very sometimes it might be necessary to take bone graft usually from the wing of the pelvis to assist the therapeutic of the osteotomy. We then use a strong titanium plate and screws to carry the osteotomy site securely while it heals.
Lateral compartment disease combined with valgus alignment can lead to progressive knee joint degeneration. In the symptomatic affected person with isolated lateral compartment disease, a varus-producing distal femoral osteotomy can unload the diseased lateral compartment. This osteotomy may be combined with other cartilage or meniscal restorative strategies to optimize knee joint preservation and ache reduction. The osteotomy may be performed with a medial closing-wedge or lateral opening-wedge method. Both strategies have been reported to enhance knee-related quality of life in patients with lateral compartment illness.
Hospital For Particular Surgical Procedure
Advantages of the medial closing-wedge approach are direct bone apposition resulting in inherent stability of the assemble, in addition to dependable bony therapeutic, and fewer hardware irritation. Advantages of the lateral opening-wedge method are a single bony reduce and due to this fact extra of an ability to adjust correction intraoperatively. However, this technique requires bone grafting and has a high fee of hardware irritation or removal. We current a surgical approach for the medial closing-wedge distal femoral osteotomy using an anteromedial-distal femoral locking plate. In sufferers presenting with lateral-primarily based knee pain, a detailed history is obtained and physical examination performed. Imaging starts with four-view knee radiographs in addition to standing full-length alignment radiographs .
Distal femoral osteotomy is indicated to appropriate deformities and malalignments such as valgus knee, a deformity the place the knee angles out from the middle of the body. It is also carried out to treat osteoarthritis in younger lively sufferers contraindicated for joint alternative. Several HTO research agree with a ± three° deviation from planning as an acceptable range . Reported outcomes are very variable with 23 to ninety two% being within the defined target range .
Other than concurrently either including bone or taking out bone, there may not be a big difference between either technique. The most necessary approach, due to this fact, could be the one which one’s surgeon feels most comfortable with performing a distal femoral osteotomy. For sufferers with ACL deficiencies, if they have important arthritis in 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 alternative surgical procedure and/or a lateral meniscal transplant with their ACL reconstructions. The next most common indication for a distal femoral osteotomy is when a patient is knock knee and needs a lateral meniscal transplant and/or a cartilage resurfacing process of the surface compartment of their knee.
In such instances there isn’t any barrier for the patient to have knee replacement surgery. The knee is fashioned by the tibiofemoral joints, where end of the femur glides over the top of the tibia and the patellofemoral joint the place the kneecap glides over the top a part of the femur. The gliding surfaces of the knee are lined with articular cartilage which helps the joint to glide smoothly. Over time the articular cartilage can turn out to be damaged or ‘worn away’ and this is called osteoarthritis. For a lateral opening wedge osteotomy, a wedge-formed section of bone is removed, and the hole is opened further to alter the alignment of the bones. A bone graft is inserted into the hole so that the bones fuse in the new alignment.

At six months comply with-up, bony fusion was achived and %MA was 48.5% from the medial fringe of the tibial plateau. Bony fusion is achieved and %MA is 48.5% from the medial fringe of the tibial plateau. Valgus deformity has improved in appearance, whereas lower limb length discrepancy improved to -0.5 cm in the left lower limb and the range of movement of the proper knee also improved to 0 to 150 levels .
Therefore, the goal of the distal femoral osteotomy is to shift the affected person from being valgus towards being varus. Oftentimes, we’ll place the affected person right into a lateral compartment unloader brace to make use of as a display screen to determine that a distal femoral osteotomy may be a helpful procedure. We have discovered that patients who have good pain relief with the use of a lateral unloader brace usually have equally good or higher ache reduction after a distal femoral osteotomy realignment process.
Dissection is taken down via the interval between the vastus medialis oblique and the intermuscular septum, exposing the medial cortex of the femur. The osteotomy site is marked with K-wires primarily based on preoperative templating. Proximal and distal osteotomy cuts are made with care taken to not 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 appropriate position using intraoperative fluoroscopy. Video 1 Distal femoral medial closing-wedge osteotomy on the best distal femur of a cadaveric specimen. Fractures of the distal femoral development plate are exceptional in that they are the third most typical development plate fracture in youngsters , but they carry a danger of development disturbance in as much as 90% of cases .
