Meril LATITUD UNCEMENTED FEMORAL STEM

The uncemented femoral stem has following basic design features:

1. Uncemented femoral stem is manufactured from Ti-6Al-4V-ELI conforming to ASTM F136-13- “Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI for Surgical Implant Applications” and ISO 5832-3:1996: ” Implant for surgery-Metallic material – Part-3, Wrought Titanium 6-Aluminium 4-Vanadium alloy” and intended to be mated with Modular femoral head through 12/14 tapered male trunnion.
2. The uncemented femoral stem is press fit, double tapered design with a hydroxyapatite (HA) coating and is intended to be implanted in prepared femur medullary canal without bone cement (press fit cementless fixation). HA coating is plasma sprayed coating conforming to ISO 13779-2:2008: “Implants for surgery — Hydroxyapatite — Part 2: Coatings of Hydroxyapatite”. Hydroxyapatite powder being used in HA coating conforms to ASTM F 1185 – 03 (2014) “Standard specification for composition of  Hydroxyapatite for surgical implants”, and ISO 13779-6 (2015): “Implants for surgery – Hydroxyapatite – Part 6 – Powders”.
3. Uncemented femoral stem has both vertical and horizontal grooves to provide rotational and axial stability.
4. Uncemented femoral stem neck has standard 12/14 taper male trunnion for connection to modular femoral head.
5. Uncemented stem has instrumentation hole at proximal region to hold the stem by instrument and insertion of stem in medullary canal.
6. Uncemented femoral stem is available in different sizes (viz. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) with three different neck angle viz. 135 Standard (for stem size 0 to size 10), 135 lateralized (for stem size 0 to size 10) and 125 Standard (for stem size 0 to size 10).
