P130 - Hip prosthesis / femoral stem
| |
Materials :
Coated shafts are made in a forged titanium alloy (ISO 5832-3) that provides an elasticity module closest to that of bone. A hydroxyapatite coating is sprayed on the proximal 2/3 of or the entire shaft (2 versions)
Shafts for cementing are made in forged stainless steel (ISO 5832-9). Their brilliant polished appearance removes the constraint of shearing at the bone/cement interface.
Characteristics :
The metaphyseal profile of the shaft ensures primary stability when embedded and in torsion. The slimmed down terminal part provides positioning that does not block the diaphyseal parts of the cortex.
Secondary stability is obtained by osteogenesis activated by the hydroxyapatite coating and the colonisation of the striations by the new growth of bone.
Lateralisation obtained through a non-homothetic translation of the neck of the femur enables the same cervico-diaphyseal angle of 130° to be retained.
The smaller dimensions of the cross-sections of cemented shafts compared with coated shafts enables a 1 mm coat of cement to be obtained by using a file of the same size as the implant.
The shafts are available with a 12/14 cone and a slimmed down neck in brilliant polish that increases articulatory amplitude while postponing a cam effect and avoiding dislocation.
The rang included 8 standard size and 8 latéralised size for each shaft version.
