DePuy identified reasons for the failure of the hip replacement system as component loosening, component malalignment, infection, fracture of the bone, dislocation, metal sensitivity and pain. Additional complications from the hip replacement system may include increased metal ion levels in the blood, bone staining, necrosis , swelling , nerve ...
In elderly people this usually would include ECG, urine tests, hematology and blood tests. Cross match of blood is routine also, as a high percentage of people receive a blood transfusion. Pre-operative planning requires accurate Xrays of the affected joint, implant design selecting and size-matching to the xray images (a process known as ...
Risks and complications in hip replacement are similar to those associated with all joint replacements. They can include infection, dislocation, limb length inequality, loosening, impingement, osteolysis, metal sensitivity, nerve palsy, chronic pain and death. [11] Weight loss surgery before a hip replacement does not appear to change outcomes ...
Though rare, metallosis has been observed at an estimated incidence of 5% of metal joint implant patients over the last 40 years. Women may be at slightly higher risk than men. If metallosis occurs, it may involve the hip and knee joints, the shoulder, [2] wrist, [3] elbow joints, [4] or spine. [5]

Doctors discovered Jackson to have lost all of the cartilage supporting his hip while he was undergoing tests following a hip injury he had on the field during a 1991 NFL Playoff game. [29] Avascular necrosis of the hip was also identified in a routine medical check-up on quarterback Brett Favre following his trade to the Green Bay Packers in ...
In total hip replacement, the generally accepted explanation [1] for osteolysis involves wear particles (worn off the contact surface of the artificial ball and socket joint). As the body attempts to clean up these wear particles (typically consisting of plastic or metal), it triggers an autoimmune reaction which causes resorption of living ...
PJIs are the most common cause of knee replacement failures, and the third most common cause of hip replacement failures. [1] As of 2017, 2.1% of hip and 2.3% of knee replacements will at some time develop a PJI. [2] The incidence of PJIs have more than tripled in the last 20 years, with the incidence expected to further increase in the future.
