Summary

This is a prospective, randomized study comparing two different bone preparation techniques for insertion of a hydroxylapatite (HA) coated titanium cementless femoral stem. Patients who receive a unilateral total hip replacement are randomized to either conventional broaching or compaction. Hypothesis: Compaction results in significantly less stem migration \[evaluated by radiostereometric analysis (RSA)\], less peri-prosthetic bone mineral density (BMD) loss \[evaluated by dual energy x-ray absorptiometry (DEXA)\], and a higher Harris hip score after two years.

Conditions

• Coxarthrosis

Interventions

Type	Name	Description
PROCEDURE	Bone preparation technique: compaction	The bone is pressed very hard together before implantation of femoral component.
PROCEDURE	Bone preparation technique: conventional technique	Bone is broached before implantation of femoral component.
