Primary osteoarthritis (primary arthrosis)
Post-traumatic osteoarthritis (post-traumatic arthrosis)

Avascular necrosis of the femoral head
Inflammatory arthritis, insofar as the remaining bone substance permits (strict diagnosis as increased fracture rate!)

Existing high risk of dislocation in prior disorders

Contraindications

Acute infection
Malignant tumours
Inadequate bone structures in the acetabulum or femur
Inadequate bone quality (e.g., osteoporosis and osteomalacia)
Insufficient patient compliance, alcohol or drug abuse
(Decompensated) renal insufficiency
