Total hip arthroplasty (THA) is undertaken to relieve pain and to restore mobility. The orthopaedic community remains divided on the influence of surgical approach in achieving functional recovery most quickly and effectively. We report a study comparing THA performed through a posterior (Posterior) against anterior approach (Heuter). Fifty patients were prospectively enrolled and randomized for Posterior or Heuter procedures. Informed patient consent and local ethics approval was obtained. All patients received an uncemented, ceramic-on-ceramic prosthesis performed by a single surgeon. Functional outcome was assessed by time to achieve milestones of walking, stair climbing, hip movement and balance. Kinematic data on level-ground walking and the effect of fatigue was assessed using a portable gait analysis system at 6-, 12-, and 24-weeks post-operatively.Introduction
Methods
The need for the stringent surveillance of new devices was recognised by the NICE review of hip replacement surgery in 2000 and led to the Orthopaedic Data Evaluation Panel (ODEP) developing criteria for post-marketing surveillance (PMS) studies. This requirement has been reinforced by the recent recall of ASR devices. The South West London Elective Orthopaedic Centre's (EOC's) comprehensive outcomes programme has been adapted to manage and coordinate multi-centre, multi-surgeon, PMS studies. The system allows any schedule and combination of patient-reported outcome measures (PROMS), clinical and radiological assessments, and complications to be collected. Typically, PROMS are collected pre-operatively and yearly by post. Baseline clinical assessment is undertaken pre-operatively, with baseline radiological assessments pre- and post-operatively. Subsequent clinical and radiological assessments are usually obtained at the ODEP-mandated time points of 3, 5, 7 and 10 years post-operatively. Patients are telephoned twice yearly to document complications and any impending change of address.Introduction
Methods
Developmental dysplasia of the hip predisposes to premature degenerative hip disease. A number of operations have been described to improve acetabular cover and have achieved varying degrees of success. We present the case of an 84-year-old woman, who underwent a shelf procedure to reconstruct a dysplastic hip 75 years ago. To date, the shelf remains intact and the hip is asymptomatic. We believe this represents the longest documented outcome of any procedure to stabilise the hip.
