The purpose of this prospective study was to
evaluate the long-term clinical and radiological outcomes of revision of
the femoral component of a total hip replacement using impaction
bone grafting. Femoral revision with an impacted allograft was performed
on 29 patients (31 hips). In all, 21 hips (68%) had grade III or
IV femoral defects according to the Endo-Klinik classification.
A total of 11 patients (12 hips) died before the ten-year follow-up
period. Of the remaining patients, 18 patients (19 hips) were followed
for 10 to 15 years; three further patients died during this time.

Aims. The aim of this study was to identify the optimal lip position for total hip arthroplasties (THAs) using a lipped liner. There is a lack of consensus on the optimal position, with substantial variability in surgeon practice. Methods. A model of a THA was developed using a 20° lipped liner. Kinematic analyses included a physiological range of motion (ROM) analysis and a provocative dislocation manoeuvre analysis. ROM prior to impingement was calculated and, in impingement scenarios, the travel distance prior to dislocation was assessed. The combinations analyzed included nine cup positions (inclination 30-40-50°, anteversion 5-15-25°), three
