Trident II Tritanium Solidback Acetabular Shell - Acetabular shell

Intended purpose

Intended for cementless fixation into a prepared acetabulum for either primary or revision Total Hip Arthroplasty. Indications for Use - Painful, disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis or late stage avascular necrosis. - Revision of previous unsuccessful femoral head replacement, cup arthroplasty or other procedure. - Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results. - Where bone stock is of poor quality or is inadequate for other reconstructive techniques as indicated by deficiencies of the acetabulum. When used with MDM Liners - Treatment of nonunion, femoral neck and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques. - Dislocation risks When used with Constrained Liner - The Trident Constrained Acetabular Insert is indicated for use in primary and revision patients at high risk of hip dislocation due to a history of prior dislocation, bone loss, joint or soft tissue laxity, neuromuscular disease, or intraoperative instability.
