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 ...
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.
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.
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).
Thompson and Epstein classification. The Thompson and Epstein classification is a system of categorizing posterior fracture/dislocations of the hip. [1][2]
An ongoing Phase 2 trial in 2016 presented data [164] showing that after 90 days, 2 out of 4 subjects had already improved two motor levels and had thus already achieved its endpoint of 2/5 patients improving two levels within 6–12 months. Six-month data was expected in January 2017. [165]
