Comparison of Two Cementing Techniques of the Femoral Component in a Hip Prosthesis

Comparison of Two Cementing Techniques of the Femoral Component in a Hip Prosthesis. A Randomized Single-blind Trial

The primary aim of the study is to compare migration of the cemented Corail stem representing polished surfaced versions of the femoral stem. Two different methods will be used for reaming the femoral canal and cementing of the stem. Radiostereometric analysis (RSA) will be used in migration measurements.

Furthermore pain, postoperative outcome and patient satisfaction will be assessed.

Inclusion Criteria:

• Patients requiring cemented primary total hip replacement.
• Patients with a diagnosis of osteoarthritis, avascular necrosis or post-traumatic arthritis
• Patients who understand the conditions of the study and are willing and able to comply with the post-operative scheduled clinical and radiographic evaluations and the prescribed rehabilitation
• Patient who signed the Ethics Committee approved specific Informed Consent Form prior to surgery

Exclusion Criteria:

• Patients who require revision of a previously implanted total hip replacement (THR)
• Patients who will receive a THR without cement
• Patients who have had a prior procedure of osteotomy on the femur
• Obese patients where obesity is severe enough to affect subject's ability to perform activities of daily living (body mass index, kg/m2: BMI >35)
• Patients with active or suspected infection
• Patients with malignancy
