X-ray of Femoral Osteotomy hardware to correct femoral rotation caused by hip dysplasia. X-ray of the right hip in female patient in early thirties. Two main types of osteotomies are used in the correction of hip dysplasias and deformities to improve alignment/interaction of acetabulum – (socket) – and femoral head – (ball), innominate osteotomies and femoral osteotomies.
Bone malrotation refers to the situation that results when a bone heals out of rotational alignment from another bone, or part of bone. It often occurs as the result of a surgical complication after a fracture where intramedullary nailing (IMN) occurs, [1] especially in the femur and tibial bones, but can also occur genetically at birth.
Rotationplasty is also performed on children with congenital femoral deficiencies. Those deficiencies cause "unstable hip joint[s] and a femur that is 50% shorter than the contralateral, normal femur." [6] This procedure gives rotationplasty patients the ability to have the use of both feet and allows them to continue living an active lifestyle.
External rotation of the femur with valgus deformity of knee may be noted. This condition does not resolve and requires surgical management. Surgical management includes valgus osteotomy to improve hip biomechanics and length and rotational osteotomy to correct retroversion and lengthening.
Normally, bone continuously breaks down and rebuilds—old bone is resorbed and replaced with new bone. The process keeps the skeleton strong and helps it to maintain a balance of minerals. [23] In the course of avascular necrosis, however, the healing process is usually ineffective and the bone tissues break down faster than the body can ...
It is performed to alleviate pain, and is a salvage procedure, reserved for condition where pain can not be alleviated in any other way. It is common in veterinary surgery. Other names are excision arthroplasty of the femoral head and neck, Girdlestone's operation, Girdlestone procedure, and femoral head and neck ostectomy. [citation needed]
High tibial osteotomy is an orthopaedic surgical procedure which aims to correct a varus deformation with compartmental osteoarthritis.Since the inception of the procedure, advancements to technique, fixation devices, and a better understanding of patient selection has allowed HTO to become more popular in younger, more active patients hoping to combat arthritis.

Type B — The femur bone is shorter on the proximal end (near the hip) and the defect affects both the femoral head (the ball) and the femoral shaft (the long part of the bone). This defect is more severe than type A deformities because it will not heal spontaneously and, at skeletal maturity, the proximal femur (lower part near the knee) will ...
