简要总结
The Aim Is To Study The Anatomic Relationship Of The Popliteal Vesseles In Two Types Of (OWHTO) Techniques (Monoplanar VS Biplanar) Which Provide More Safe Technique To The PV
详细描述
Open wedge High tibial osteotomy (OWHTO) is a common surgical Procedure that is utilized to correct knee varus deformity and prevent development or advancement of medial compatment knee osteoarthritis.
By turning the mechanical weight-bearing axis to the lateral side it correct lower limb alignment,decrease medial compartment load,pain,arthritic changes, postpone the need for arthroplasty and allow cartilage regeneration.
Like any other surgical procedure (OWHTO) has its own complications.injury to the popliteal vessels (PV) is catastrophic and limb threatening compliation that had been reported with prevalence rate ranging from 0.4% to 1.7% PV runs close to the posterior tibial cortex it might be injured while taking osteotomy cut. To avoid this problem many studies with different tools done to define PV position and its relations to provide safe technique for osteotomy.
(OWHTO) has different methods: Monoplanar and Biplanar osteotomy are most popular,both techniques differ in cut level and shape.
In this study the investigators compare between the two methods (Monoplanar VS Biplanar) concerning their proximity and safety to the PV .
