Bipolar Head
The iNSitu Bipolar Hip System consists of a factory assembled UHMWPE liner in a cobalt chrome outer shell, and UHMWPE retention ring with a Ti alloy spring. The Bipolar Heads include outer diameters ranging from 38 to 60mm, in 2mm increments, to accommodate patient anatomy. The smaller Bipolar Heads (38 to 42mm) have an inner diameter that mates with a 22mm diameter Femoral Head; the larger Bipolar Heads (44 to 60mm) have an inner diameter that mates with a 28 mm diameter Femoral Head. The iNSitu Bipolar Hip System may be used in conjunction with any iNSitu Total Hip System Femoral Stem.
