Abstract:
OBJECTIVE: To study the clinical influence of fe moral quality on cementless hip replacement and to evaluate cortical index (CI) for femoral quality in order to guide prosthesis choice and rehabilitation. METHODS: Forty-nine cases of cementless hip replacement were followed up for average 3.5 years, 42 of whom had X-ray films on preopera tion or operation day. RESULTS: Harris scores and patients' satisfaction were low bu t pain was significant and prolonged when cortical indices were low. CONCLUSIONS: CI is a reliable semi-quantity parameter for clin ical evaluation of femoral quality. Osteoporosis patients predispose to thigh pa in. Lag for full-weight loading and avoidance for torsion motion can contribute to less pain when CI<=2.2.
