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.
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.
Typically, people with hip dislocations present with severe pain and an inability to move the affected leg. Diagnosis is made by physical exam and plain X-rays of the hips. A CT scan is recommended following reduction to rule out complications. Complications include osteonecrosis, femoral head fractures, and posttraumatic osteoarthritis.
A variety of methods may be used to treat the most common being the total hip replacement (THR). However, THRs have a number of downsides including long recovery times and the life spans of the hip joints (often around 20 to 30 years). THRs are an effective means of treatment in the older population; however, in younger people, they may wear ...
Peri-acetabular osteotomy (PAO) surgery can be used to realign the hip joint in some adolescents and adults. Subsequent treatment with total hip arthroplasty (hip replacement) is complicated by a need for revision surgery (replacing the artificial joint) owing to skeletal changes as the body matures, loosening/wear or bone resorption.
Complications. Nonunion, failure of the fracture to heal, is common in fractures of the neck of the femur, but much more rare with other types of hip fracture. Avascular necrosis of the femoral head occurs frequently (20%) in intracapsular hip fractures, because the blood supply is interrupted.
The Oxford Hip Score (OHS) is a standard patient-reported outcome (PRO) measure, or PROM, developed to assess function and pain in patients undergoing total hip replacement (THR) surgery, particularly in the context of clinical trials.
The Cincinnati Prehospital Stroke Scale (abbreviated CPSS) is a system used to diagnose a potential stroke in a prehospital setting. It tests three signs for abnormal findings which may indicate that the patient is having a stroke.
John Charnley. Sir John Charnley, CBE, FRS [1] (29 August 1911 – 5 August 1982) was an English orthopaedic surgeon. He pioneered the hip replacement operation, [4] which is now one of the most common operations both in the UK and elsewhere in the world, and created the "Wrightington centre for hip surgery".
Signs and symptoms. The classic symptom of subarachnoid hemorrhage is thunderclap headache (a headache described as "like being kicked in the head", or the "worst ever", developing over seconds to minutes). This headache often pulsates towards the occiput (the back of the head).
