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 posterior (Moore or Southern) approach accesses the joint and capsule through the back, taking piriformis muscle and the short external rotators of the femur. This approach gives excellent access to the acetabulum and femur and preserves the hip abductors and thus minimizes the risk of abductor dysfunction post operatively. It has the ...
Joint replacement is a procedure of orthopedic surgery known also as arthroplasty, in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. Joint replacement surgery is often ...
Subclinical electromyographic abnormalities of both the superior and inferior gluteal nerves have been described in up to 77% of patients after total hip replacement, regardless of the surgical approach. [9] The posterior approach is the most common and practical of those used to expose the hip joint.
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).
Piriformis syndrome is a condition which is believed to result from nerve compression at the sciatic nerve by the piriformis muscle. [2][5] It is a specific case of deep gluteal syndrome. [6] The largest and most bulky nerve in the human body is the sciatic nerve. Starting at its origin it is 2 cm wide and 0.5 cm thick.
Williams flexion exercises (WFE) – also called Williams lumbar flexion exercises – are a set of related physical exercises intended to enhance lumbar flexion, avoid lumbar extension, and strengthen the abdominal and gluteal musculature in an effort to manage low back pain non-surgically. The system was first devised in 1937 by Dallas ...
The Thompson and Epstein classification is a system of categorizing posterior fracture/dislocations of the hip. [1][2]
