    The GMRS Proximal Femoral Components have over a decade of clinical history. The neck length has been increased to help improve range of motion and better meet the needs of various patient anatomies. The GMRS Proximal Femoral Components are fully compatible with all Stryker V40 femoral heads. The components continue to be available in two configurations, standard and trochanteric, but are now also available in neutral, left and right anteverted orientations.
