Design rationale

Double-ball construction

The bipolar concept is a double ball. The outer shell generally stays still in the natural acetabulum. The main articulation is the multi-directional rotation between the femoral head and the inside of the outer shell. Some sliding between the outer shell and the acetabulum or cartilage can also occur.

Matched head diameter

The head diameter must always match the inner diameter of the bipolar head. Bipolar trial cups and a trial impactor measure the acetabulum, so the outer diameter is chosen to fit it.

Indications

Non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, ankylosis, protrusio acetabuli and symptomatic developmental hip dysplasia
Inflammatory arthritis such as rheumatoid arthritis
Surgical correction of deformity causing functional impairment
Hip fractures
Reconstruction or compensation of bone defects, for example tumour-related
