CAPTIV DM Ti/HAC Coated Dual Mobility Press-Fit Acetabular Cup - Metallic acetabulum prosthesis

Intended purpose

Hemi and total hip arthroplasties are indicated for the treatment of symptomatic pain and/or functional problems of the hip in patients whose skeleton is mature and only when pain killer medication and correctly followed conservative treatment have failed. For the patient, his anatomy and the structure of his articulation will need to be adapted to receive the selected implant(s). The recommended indications for dual mobility cup are: − Primary arthroplasties for patients at high risk of dislocation (severe neurological affliction, neu-ropsychiatric disorders, addictions and severe neuromuscular deficiencies), − Revision arthroplasties in cases of recurrent dislocations for patients at high risk of articular in-stability.
