The acetabular labrum is a fibrous structure, which surrounds the femoral head. It forms a seal to the hip joint, [ 15 ] although its true function is poorly understood. Recent evidence has demonstrated that this hydraulic seal is vital for maintaining stability of the ball and socket joint [ 16 ] and reducing contact pressures of the femur to ...
The primary aim of surgery is to correct the fit of the femoral head and acetabulum to create a hip socket that reduces contact between the two, allowing a greater range of movement. [30] This includes femoral head sculpting and/or trimming of the acetabular rim. [30] [31] Surgery may be arthroscopic or open. [7]
Hip resurfacing is a surgical alternative to total hip replacement (THR). The procedure consists of placing a cap (usually made of cobalt-chrome metal), which is hollow and shaped similarly to the cap of a mushroom, over the head of the femur while a matching metal cup (similar to what is used with a THR) is placed in the acetabulum (pelvis socket), replacing the articulating surfaces of the ...
Hip replacement surgery can be performed as a total replacement or a hemi/semi(half) replacement. ... The average cost of a total hip replacement in 2012 was $40,364 ...
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.
The acetabular labrum is a fibrocartilagenous structure similar in composition to the meniscus. It is a ring of tissue that surrounds the acetabulum of the pelvis, and allows the head of the femur to articulate smoothly and efficiently with the acetabulum. The labrum plays an important role in maintaining the biomechanical stability of the hip ...
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).
Protrusio acetabuli is an uncommon defect of the acetabulum, the socket that receives the femoral head to make the hip joint. The hip bone of the pelvic bone/girdle is composed of three bones, the ilium, the ischium and the pubis. In protrusio deformity, there is medial displacement of the femoral head in that the medial aspect of the femoral ...
