Bipolar head with mounted metal plug head

The BioBall® Duo Head Bipolar is a bipolar head with the outer shell, the inlay and the inner plug head already pre-assembled. When used in combination with the BioBall™ adapter in patients with largely intact acetabulum, this allows femoral neck length correction (see BioBall® standard adapter) along with medialisation/lateralisation and correction of retro- or antetorsion, thereby producing optimum surgical results.

TECHNICAL DATA

• Sizes: 42 mm – 58 mm
• Mounted metal head in 28-mm or 32-mm diameters
• Shell and head material: Vivium®
• Inlay material: UHMWPE

FEATURES

• Solution for (e.g.) medial femoral neck fractures
• Usable in natural acetabulum with residual connective tissue
• Can be combined with all BioBall® adapters
• Joint socket self-aligns under loads, ensuring stable valgus positioning
• Polished, high-gloss outer cup with inlay and plug head positioned to prevent dislocation
• Pre-assembled for easier surgical usage
• Allows intraoperative correction of neck length, medialisation / lateralisation and correction of retro- or antetorsion

INDICATIONS

• Advanced wear of the proximal femur due to degenerative, post-traumatic or rheumatic diseases with well-preserved acetabulum, including medial femoral neck fractures and advanced avascular necrosis of the femoral head, which cannot be treated using conservative or joint-preserving surgical procedures
• Hemiarthroplasty with unpromising femoral neck fractures to be treated by osteosynthesis
