Comparison of two hydroxyapatite-coated femoral stems: clinical, functional, and bone densitometry evaluation of patients randomized to a regular or modified hydroxyapatite-coated stem aimed at proximal fixation.

Clinical function, bone mineral density (BMD), and radiographs of 80 randomly allocated, hydroxyapatite-coated femoral stems of two differing lengths were studied for 2 years. The short stem was optimized for proximal fixation. The predictive value of bone densitometry was also studied.

The "Oxford Heup Score": the translation and validation of a questionnaire into Dutch to evaluate the results of total hip arthroplasty.

Background: The evaluation of a total hip prosthesis would be most complete if the opinion of the patient, surgeon and the radiographs are combined. Disease specific patient outcome questionnaires are scarce, especially in Dutch.

Methods: The disease-specific 12-item questionnaire on the perception of patients with total hip replacement was translated into Dutch.
