The design of the Modular Bipolar System consists of two components – outer shell and insert – assembled intra-operatively and allows use of standard metal or ceramic heads. This offers surgeons an alternative for hemiarthroplasty procedures to meet individual patient’s needs.
Other benefits of the Modular Bipolar System are:
• Ease of assembly
• Self-aligning effect
• Maximum head security
• Accurate fit with sizes ranging from 38–60mm
• Available for 22, 28 and 32mm femoral heads
Indications and Contraindications
Combined with the wide range of Zimmer femoral components and the surgeon’s preferred technique the Modular Bipolar System is an efficient approach to femoral neck fractures and avascular necrosis.
The hemiarthroplasty is contraindicated when the acetabulum is diseased (coxarthrosis, hip dysplasia, infections and rheumatoid arthritis).
The Bipolar Components are available in a wide range of sizes from 38–60mm in 2mm increments. Available options include also 1mm increment ranging from 42–54mm. The standard femoral heads – 22mm, 28mm, 32mm – are available in lengths from –4mm to +8 mm to provide optimal recreation of the patient’s anatomy.
