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

Intended purpose

The Device is a dual mobility cup for use in total hip arthroplasty. 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 medicamentation 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). Indications for total or partial hip arthroplasty are: - Degenerative non inflammatory hip disease (coxarthrosis, arthritis of the hip). - Inflammatory hip disease (rheumatoid arthritis, post traumatic arthritis). - Metabolic hip disease (chondrocalcinosis). - Post Traumatic degenerative arthritis. - Avascular necrosis. - Congenital dysplasia of the hip. - Functional repair of a recent trauma (fracture, dislocation) - Revision of a failed conservative surgery, osteosynthesis, partial or total arthroplasty. - Tumoral surgery when affecting the hip joint. The recommended indications for dual mobility cup are: - Primary arthroplasties for patients at high risk of dislocation (severe neurological affliction, neuropsychiatric disorders, addictions and severe neuromuscular deficiencies), - Revision arthroplasties in cases of recurrent dislocations for patients at high risk of articular instability.

Functional description

The CAPTIV DM acetabular cup is a modular, cementless acetabular implant. The outer surface has reliefs, shallow concentric grooves increase the surface in contact with the bone, it is covered with a bilayer coating of titanium and hydroxyapatite. CAPTIV DM is not coated on its 3mm circumferential edge. The anchorage in the acetabulum is obtained by press-fit and peripheral pressfit is proportional to size with an average of 1mm. The pole is congruent with bone reamed ensuring the press fit.
