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. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures.
Heterotopic ossification of varying severity can be caused by surgery or trauma to the hips and legs. About every third patient who has total hip arthroplasty (joint replacement) or a severe fracture of the long bones of the lower leg will develop heterotopic ossification, but is uncommonly symptomatic.
It usually presents as joint pain, erythema (redness of the joint or adjacent area), joint swelling and sometimes formation of a sinus tract ( a tract connecting the joint space to the outer environment). PJI is estimated to occur in approximately 2% of hip and knee replacements, and up to 4% of revision hip or knee replacements.
After surgery with preventive treatment, VTE develops in about 10 of 1000 people after total or partial knee replacement, and in about 5 of 1000 after total or partial hip replacement. About 400,000 Americans develop an initial VTE each year, with 100,000 deaths or more attributable to PE.
In adults, septic arthritis most commonly causes pain, swelling and warmth at the affected joint. [2] [11] Therefore, those affected by septic arthritis will often refuse to use the extremity and prefer to hold the joint rigidly. Fever is also a symptom; however, it is less likely in older people. [12]
As with all arthroscopic procedures, because the hip arthroscopy is undertaken with fluid in the joint, there is a risk that some can escape into the surrounding tissues during surgery and cause local swelling. Occasionally, this causes skin blistering. However, swelling usually resolves after 24 hours without intervention.
Greater trochanteric pain syndrome (GTPS), a form of bursitis, is inflammation of the trochanteric bursa, a part of the hip. This bursa is at the top, outer side of the femur, between the insertion of the gluteus medius and gluteus minimus muscles into the greater trochanter of the femur and the femoral shaft. It has the function, in common ...
Symptoms and signs. Transient synovitis causes pain in the hip, thigh, groin or knee on the affected side. [5] However, children with transient synovitis of the hip can usually weight bear with varying degrees of limping. There may be a limp (or abnormal crawling in infants) with or without pain.
While bone resorption is commonly associated with many diseases or joint problems, the term osteolysis generally refers to a problem common to artificial joint replacements such as total hip replacements, total knee replacements and total shoulder replacements.
After hip replacement, hip prosthesis zones are regions in the interface between prosthesis material and the surrounding bone. These are used as reference regions when describing for example complications including hip prosthesis loosening on medical imaging.
