Modulus-R
Modulus & Modulus-R treat complex primary and simple revision cases. Modularity allows the separation of bony fixation from biomechanical restauration.
The Modulus Stem utilizes a modified Wagner cone to gain maximum fixation
The Modulus family allows intra-operative versatility with modular necks
Small sizes are available for narrow canals
About
The Modulus uncemented stem is dedicated to complex primary and simple revision cases.
The Modulus stem utilises a modified Wagner cone to gain maximum fixation distally whilst the range of modular necks allow for the natural biomechanics to be rebuilt. The stem is intended to provide primary stability with optimal stem fixation in the femoral canal. Small sizes are also available for narrow canals. Correct biomechanical alignment is achieved thanks to its range of modular necks (restore offset, anteversion, retroversion and implant hight). The reduced antero-posterior cross section of the neck region provides a wide ROM [4]. An excellent osteo-integration can be seen with the Modulus stem [5].When a distal fixation is necessary, the orthopedic surgeon can choose LimaCorporate’s Modulus-R. Its double tapered profile with two different conicities supports distal fit and proximal fill. Compared to Modulus, Modulus-R stems have an extended length of 140mm. Modulus stem are 120mm in length.
Please refer to the Primary Standard Stems section to learn more about the Modulus Stem.
