Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi/semi(half) replacement.
Hip dislocations can also occur following a hip replacement or from a developmental abnormality known as hip dysplasia. Hip dislocations are classified by fracture association and by the positioning of the dislocated femoral head. A posteriorly positioned head is the most common dislocation type.
The modified posterior MIS approach to hip resurfacing and total hip arthroplasty (hip replacement) displays a host of advantages to the patient: Less post-operative pain; Less soft tissue damage and pressure on muscle fibres. Shorter hospital stay; Lower blood loss; Smaller incision; Quicker return to work and functional activities
The capsule of hip joint, articular capsule, or capsular ligament is strong and dense attachment of the hip joint . Anterosuperiorly, it is attached to the margin of the acetabulum 5 to 6 mm. beyond the labrum behind; but in front, it is attached to the outer margin of the labrum, and, opposite to the notch where the margin of the cavity is ...
This would involve replacing both the acetabulum (hip socket) and the head and neck of the femur. The purpose of this procedure is to relieve pain, to restore range of motion and to improve walking ability, thus leading to the improvement of muscle strength.
The head of the femur is relevant to orthopedic surgery because it can undergo avascular necrosis and consequent osteochondritis dissecans. The femoral head is removed in total hip replacement surgery.
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. This includes femoral head sculpting and/or trimming of the acetabular rim.
Hip resurfacing, sometimes called hip shaving, is preferred over a total hip replacement for elite athletes, Su said, because it preserves more of the femur, uses a metal alloy made of cobalt and ...
The posterior pituitary (or neurohypophysis) is the posterior lobe of the pituitary gland which is part of the endocrine system. The posterior pituitary is not glandular as is the anterior pituitary.
A multiaxial joint, such as the hip joint, allows for three types of movement: anterior-posterior, medial-lateral, and rotational. A multiaxial joint ( polyaxial joint or triaxial joint ) is a diarthrosis that allows for several directions of movement.
