Conditions

C05.550.114.606.400: Hip coxarthrosis, osteoarthosis M16

Interventions

Group 1: Transgluteal surgical approach to gain access to the hip joint. This approach splits the gluteus medius muscle to create joint access. Group 2: Anterolateral minimally invasive surgical appro

Eligibility

Age

No minimum to 80 Years

Inclusion criteria

Inclusion criteria: 1. Males or females with coxarthrosis for which cement-free implantation is indicated. 2. Written informed consent of patient.

Exclusion criteria

Exclusion criteria: 1. Pregnancy. 2. Patients in whom the indication for implantation of the hip endoprosthesis is due to a high level of dysplasia or a congenital luxation. 3. Patients in whom exists the indication for implantation of a cemented hip endoprosthesis. 4. Patients who have already undergone an operation in any other area of the hips or the rest of pelvis or are older than 80 years. 5. Patients in whom there is advanced arthrosis or arthrodesis in another joint of the lower extremity. 6. Patients with functionally poor endoprosthesis of the lower extremity. 7. Patients with severe spinal degeneration and / or deformation. 8. Patients with overt osteoporosis or patients for which a permanent medication (eg corticosteroids, anticoagulants) resulting in changes in bone density can be expected. 9. Patients with tumors in the pelvis or the femur. 10. Patients who have already received local radiation treatment for tumors in the area of the pelvis and the femur. 11. Patients who are ill are in a dispute. 12. Patients who have limited legal capacity or incapacity.
