Hip Arthropathy
Conditions
Brief summary
Assessment of subsidence of cementless stem following arthroplasty for fracture neck of femur.
Detailed description
Neck of femur fractures are occurring at an increased incidence, Functionally independent patients without cognitive impairment can expect reasonable life expectancy, this indicates the need for a durable surgical option that optimises the chance to return to pre-injury functional status, with minimal risk of complications and reoperation. THA should be considered the gold standard producing better functional and quality of life outcomes lower reoperation rates and better cost effectiveness. THA is associated with better functional outcomes and a lower risk of revision surgery in self-sufficient, physically active patients , Instability is the leading complication of conventional THA and occurs with a higher incidence ,THA remains the option of choice as it provides better functional outcomes. Although the clinical outcomes of total hip arthroplasty (THA) in elderly patients with femoral neck fracture were reported to be better than hemiarthroplasty, hemiarthroplasty was frequently recommended in cases where the patient has a low functional level and/or osteoporosis and high rates of postoperative dislocation of total hip arthroplasty. Hip joint replacement surgery is considered one of the most successful operations due to its high success and low complication rate , one possible risk factor for early failure of total hip arthroplasty (THA) is the subsidence of the femoral stem , Cementless THA in particular could be susceptible to subsidence. Cementless femoral stems ideally achieve direct integration between the stem surface and endosteal bone with the aim of decreasing the incidence of aseptic loosening. Subsidence is defined as a distalization of the femoral stem in reference to the greater trochanter. Measurement of subsidence of uncemented femoral stems can be used to evaluate the likelihood of long term stem component loosening and therefore clinical failure .

Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of subsidence of cementless stem following arthroplasty for fracture neck of femur. | an average of 1 year post operatively | Radiological evaluation of stem subsidence by standing anteroposterior radiograph on hip joint 1 year post-operatively to be compared with the previous anteroposterior hip radiograph that was done immediately after operation and assessment of subsidence by measuring the distance between the apex of major trochanter and the stem shoulder or measuring the distance between stem shoulder of hip prosthesis and the most prominent point of lesser trochanter |
Secondary
