STANDING THE TEST OF TIME

The Exeter V40 stem The V40 trunnion has been incorporated onto the Exeter stem as part of the standardization of the Stryker Howmedica Osteonics hip range to a single trunnion design. No aspect of the stem design that resides within the cement mantle has been modified. The V40 has been included with minimal change to the neck of the prosthesis as illustrated in Figure 1. The Exeter V40 stem introducer To assist ease of implantation of the Exeter V40 implant, a V40 stem introducer has been developed. It provides for a positive engagement between the introducer and a dimple in the lateral shoulder of the prosthesis, see Figure 2 inset. The dimple has been placed in a region of low tensile stress. The technical requirement for the stem introducer was not to change the method of releasing the stem. This has been achieved through an evolution of the original stem introducer design, retaining the connection with the trunnion protector so that the Exeter V40 stem can still be implanted with the original stem introducer. A smooth trigger action mechanism, carefully positioned in relation to an ergonomically designed handle, ensures complete control of the V40 stem introducer while it is being released from the stem, without disturbing the cement mantle. Figure 1 The V40 trunnion superimposed on the previous Exeter trunnion, (indicated in white) showing no change to the stem design residing within the cement mantle. The Exeter V40 stem increased range of motion The Exeter V40 stem, with a smaller diameter neck at the base of the trunnion, will afford an increase in range of motion. This increase in ROM will depend on the chosen diameter of the femoral head, as illustrated in Table 1.

The Exeter V40 system provides: Increased implant size range Increased head offset options Increased range of motion State-of-the-art stem introducer Easy to use modular rasps No change to the long established Exeter design principles The Exeter V40 Modular Rasps: From pre-operative templating to final implantation, the goal of the Exeter Instrumentation is to provide an easy-to-use instrument system that improves operating room efficiency. For accurate trialing, modular Exeter V40 Trial Necks feature a V40 trunnion 1 to replicate the Exeter V40 implant. The modular neck trials will allow the operating surgeon to trial different stem offsets without having to remove the rasp from the femoral canal. In addition, it will also enable the operating surgeon to work on the acetabulum while leaving the rasp in place. The modular rasp system is designed to achieve a high level of simplicity and precision while allowing greater intra-operative flexibility. See Figure 3 & 4. Figure 3 Exeter Modular Rasp. The Exeter V40 enhanced range of options Three new stem sizes have been added to the Exeter V40 range, bringing the number of stem sizes up to twenty-four, spread over a range of six offsets. The new sizes are: 44mm offset No.0 50mm offset No.1 50mm offset No.2 The new stems have been subject to rigorous testing to confirm their mechanical performance will meet the standards set by the existing range. Figure 4 Exeter V40 Neck Trial. 1 Surgeons who would like to implant Exeter TM V40 TM Hips while continuing to utilize the monobloc rasp system and the impactors will be required to use a different set of trial heads, the Exeter TM Trial Heads for Monobloc Rasps /Exchange Impactors, for trial reduction during surgery.
