Richard Berger: "2 incision" technique + fluoroscopy. Thomas P.Sculco: posterior approach. Innsbruck (Prof.Nolger): Direct anterior. Some MIS approaches for THA have been largely abandoned by surgeons, most especially Richard Berger's approach. None of the above approaches offer a fluoroscopy-free approach to Minimal Invasive Hip Resurfacing.
The analysis of 402,051 hip replacements showed that 6.2% of metal-on-metal hip implants had failed within five years, compared to 1.7% of metal-on-plastic and 2.3% of ceramic-on-ceramic hip implants. Each 1 mm (0.039 in) increase in head size of metal-on-metal hip implants was associated with a 2% increase in failure rate. [60]
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 ...
Injuries to the peripheral nerves occur in 0.5% to 8% of patients undergoing total hip replacement. [2] The posterior approach has been assessed most widely and is perhaps the most frequently used, but it is also the one most likely to be associated with damage to the inferior gluteal nerve since this structure is not usually seen.
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.
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).
Click image to see video illustration of the three types. Femoroacetabular impingement (FAI) is a condition involving one or more anatomical abnormalities of the hip joint, which is a ball and socket joint. [1] It is a common cause of hip pain and discomfort in young and middle-aged adults. [2]
The Sims position, or left lateral Sims position, named after the gynaecologist J. Marion Sims, is usually used for rectal examination, treatments, enemas, and examining patients for vaginal wall prolapse. [1][2] The Sims Position is described as in the person lying on the left side, left hip and lower extremity straight, and right hip and knee ...
