PM ProMotioin Modular Revision Stem

PM ProMotioin Modular Revision Stem

Category: Permedica Orthopedics

INTENDED PURPOSE: 

The PM ProMotion is a modular stem utilized in hip reconstruction interventions combined with a femoral head and an

acetabular cup. Device anchorage is achieved through primary press fit stabilization or by using bone cement depending on the stem used.

The PM ProMotion is a revision stem with distal anchorage, indicated in cases of revision due to various factors i.e. aseptic loosening and periprosthetic fractures, even in cases of serious bone loss in the proximal region of the femur, wherever the distal region of the femur present a structure still able to guarantee a correct and long lasting primary mechanical anchorage through the press fit technique.


MATERIALS:

            All the components are made of Titanium Aluminium Niobium forged alloy (Ti6Al7Nb) - ISO5832/11


STERILIZATION:

        Method: Irradiation (Beta or Gamma rays - nominal dose 25 kGy) or vaporized Hydrogen Peroxide (VH2O2).

        Validity: 5 years (Beta) - 10 years (Gamma-VH2O2).

PM ProMotion
Modular Revision Stem


Versatile system


(A)(B)  Revision Diaphyseal stems STRAIGHT or CURVED in different lengths and diameters* with millimetric increments for cementless use.


(C) Revision Diaphyseal stems STRAIGHT (140 e 200mm) in diameters 12,14 and 16mm for cemented use.


(D) DISPLASY Diaphyseal Stem (100mm) in different diameters* with millimetric increments for primary cementless use.


(E) (F) Metaphyseal Body STANDARD (130°) and LATERALIZED (127° offset 5mm) in 50, 60 and 70mm lengths.


(G) The Extension Body allows elongation of the total implant length of 30mm.


(H) (I) Locking Screw with TiN coating: guarantees optimal locking of the components through torque limiter tightnening. The Long version is used with the Extension Body.


(L)Sealing Cap to seal the lodging hole of the Locking Screw (included in the packaging of the Metaphyseal Body).

Modular Revision Stem


Cemented Stem


To be used in those cases where the quality of the bone should not be so good to guarantee an optimal pressfit

fixation. 

The stem has circular cross-section with longitudinal grooves to ensure rotational stability particularly designed to avoid stress transmission at the cement/prosthesis interface . 


Available only in STRAIGHT version in 12, 14 and 16mm diameters and two lengths (140 and 200mm).

Displasy Stem


Modular solution for primary replacement in cases of deformity such as displasies (CHD) or any other condition with altered anatomy of the proximal femur.

The stem has circular section with longitudinal ribs designed to slightly penetrate into the cortical bone, conferring a high grade of rotational stability and avoiding rotational stress concentration at the bone

interface.

Range of diameters from 13 to 22mm in single length (100mm)*. * To b e u s e d w i t h S H O RT M e t a p hy s e a l B o d y ( 5 0 m m ) Standard or Lateralized.






Modular construction


Thanks to the modular construction it is possible to achieve a total stem length between 190 and 300mm by combining the Metaphyseal Bodies (50, 60 and 70mm) and the Extension Module (+30mm).
