Femoral varization osteotomy is a surgical method often used to correct deformities within the knee valgus. This procedure may be carried out in chosen sufferers with lateral knee compartment overload to cut back the increased stress between the lateral femoral condyle and the lateral tibial plateau. In 27 osteotomies, the imply age was 47.15 years old, ranging from 25 to sixty one years old.
For most patients they will put as a lot weight via the operated leg because the pain will enable, the plate is not going to break. Certain sufferers who are vulnerable to having weak bone structure shall be advised to place less weight via the recovering limb as they stroll. They should not eat from anything after midnight the evening earlier than, they can have water only up till 5am.
The mediolateral diameter of the osteotomy web site is measured intraoperatively by measuring the size of the two preliminary guidewires which are placed from medial to lateral. The intraosseous lengths of the anterior and posterior guidewires are then averaged to provide the diameter reference for the chart.10 This wedge measurement should be used to information placement of the second set of 2 guidewires that determine the wedge resection size. Using fluoroscopic steerage, a information pin is placed approximately 2 to three fingerbreadths proximal to the lateral epicondyle and aimed simply proximal to the medial epicondyle. This will determine the angle of the osteotomy made first with the oscillating noticed, and followed by osteotomes.
- Both medial closing-wedge and lateral opening-wedge osteotomies of the distal femur have been reported for correction of genu valgum.5 Patient-reported knee high quality of life is improved by either technique.6, 7, eight, 9 Advantages of each approach are detailed in Table 1.

- This database will further our detailed understanding of osteotomy surgical procedure.
- Only the examine by van der Woude et al. investigated the postoperative clinical outcome after a cDFO up to now and reported a Lysholm score of 73 factors and a ache degree of three .
We advocate that these sufferers be adopted for a number of years, ideally till skeletal maturity. One patient introduced with persistent discomfort on the plaque despite conservative therapy. A female patient presented with delayed consolidation and with a fracture after falling from her personal height. The lesion was submitted to medial and lateral stabilization for bone consolidation. Valgisation osteotomies lead to a big improvement in all medical scores with the demonstrated treatment protocol. Since cDFO offers comparable radiological and clinical results as oHTO, this is a crucial therapy possibility for varus deformities of femoral origin.
A Dedicate Instrumentation For A Exact Surgical Procedure
To assess for useful and scientific standing previous to admission, we used the Lysholm score, the, Short-Form-36 Health Survey (SF-36), and the Visual Analog Scale . We used an observational cohort research design and prospectively carried out preoperative long standing radiographs , lateral x-rays and clinical questionnaires (SF-36, Lysholm rating, VAS). Postoperative LSR and lateral x-rays had been obtained on average 18 months postoperative and postoperative clinical questionnaires at final visit . A subgroup evaluation of the totally different surgical techniques (oHTO vs. cDFO) was performed, with regards to radiological and medical outcomes.
• With larger corrections, it’s helpful to perforate the medial cortex with a drill bit to allow a controlled opening. Potential risks utilizing this technique include malcorrection, intra-articular fracture, neurovascular damage, malunion or nonunion, and hardware irritation. Other general postoperative complications might include deep vein thrombosis, pulmonary embolism, infection, arthrofibrosis, and anterior knee pain.three, 11, 12 See Table 3. Osteotomes are used to complete the osteotomy in safe and efficient method.
Another possible cause is removing of the lateral meniscus which is sometimes required after damage to the knee. The Distal Femoral Osteotomy System utilizes the identical rules of design featured in the Tibial Osteotomy System. Specifically designed femoral osteotomy plates take into account the anatomical differences between the distal femur and proximal tibia. Wang J.-W., Hsu C.-C. Distal femoral varus osteotomy for osteoarthritis of the knee. With retractors positioned along both the anterior and posterior cortices to guard the quadriceps tendon and posterior neurovascular buildings, respectively, the sagittal saw is marked to the depth of the cut to avoid violation of the lateral cortex.
Here, we report a case of distal femoral osteotomy for a valgus knee after a distal femoral perichondral ring harm (Rang’s sort VI) in a rising male patient. Prior to the surgery, Dr. Mansour orders a collection of imaging research to estimate the extent of deformity and calculate the diploma of correction for correct alignment of your legs. A 8 to 12 cm incision is made in the upper leg close to the knee from the facet . The muscles and blood vessels are protected and the thigh bone is approached. With the assistance of an oscillating noticed, a reduce throughout a lot of the bone is made and a wedge-formed instrument with markings is inserted to measure and ensure the bone gap’s dimension. The bone is secured with a metal plate, a fixation gadget that provides steady fixation of the osteotomy.
Dissection is taken down via the generally avascular aircraft in the vastus medialis indirect fascia and the intermuscular septum . If small perforating vessels are encountered, these are coagulated with the electrocautery. The proximal third of the medial patellofemoral ligament, as well as the distal insertion of the vastus medialis indirect, could be incised to permit mobilization of the quadriceps and adequate publicity of the distal femur for plate positioning. The intermuscular septum adjacent to the medial femoral cortex is then incised in line with the femur using electrocautery. A blunt rasp or Cobb elevator can be utilized to rigorously dissect delicate tissues off of the posterior femur with care taken to work instantly on the posterior femoral cortex .
To describe the surgical technique of distal closing-wedge femoral osteotomy and a instances sequence submitted to this method. This examine evaluates radiological and scientific midterm outcome of re-alignment procedures in case of varus deformtities. The importance of comparing preoperative planning with actual postoperative alignment and the associated medical outcome is emphasised.
