Degree of bulging of the femoral head-neck junction: In normal conditions there is a symmetric concave contour at the junction of the femoral head and neck. Loss of this concavity or bone bulging may lead to cam type impingement. The degree of this deformity can be measured by the alpha angle.
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.
Femoropopliteal bypass surgery is mainly used to treat cases of femoral artery blockage that cause more severe symptoms that restrict completion of daily tasks such as peripheral artery disease and claudication, or cases that have not responded well to other treatment options . Before surgery is considered, adjustments are made to lifestyle ...
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.
THRs are an effective means of treatment in the older population; however, in younger people, they may wear out before the end of a person's life. [22] Other techniques, such as metal-on-metal resurfacing, may not be suitable in all cases of avascular necrosis; its suitability depends on how much damage has occurred to the femoral head. [23]
Rotationplasty was first performed by Joseph Borggreve in 1927. [2] He performed the procedure on a 12-year-old boy who suffered from tuberculosis.However, the procedure was not well known until 1950, when Dutch orthopedist Cornelis Pieter van Nes (1897–1972) reported the results of rotationplasty procedures.

An investigation by People for the Ethical Treatment of Animals, or PETA, found that a New York operation expected a worker to feed around 500 birds three times a day. The pace ruptured organs and ...
Posterior dislocations is when the femoral head lies posteriorly after dislocation. [5] It is the most common pattern of dislocation accounting for 90% of hip dislocations, [5] and those with an associated fracture are categorized by the Thompson and Epstein classification system, the Stewart and Milford classification system, and the Pipkin system (when associated with femoral head fractures).
