Orthopaedic fixation component and method

摘要

An orthopaedic fixation component attachable to a femur, said femur defining a femur shaft, a femur head and a femur neck extending therebetween, said femur further defining a greater trochanter limiting laterally said femur neck, said orthopaedic fixation component comprising: a shaft section fixation portion and an end section fixation portion extending substantially longitudinally therefrom, said shaft section and end section fixation portions being respectively securable to said femur shaft and said greater trochanter; said end section fixation portion including a pair of end arms, said end arms being configured, sized and positioned to delimit a trochanter receiving recess for substantially fittingly receiving a prominent portion of said greater trochanter.

1. A fixation component securable to a femur, said femur defining a femur shaft and a greater trochanter extending from said femur shaft, said greater trochanter defining an anterior facet and a lateral facet, said fixation component comprising:
a shaft section fixation portion, said shaft section fixation portion including a substantially elongated shaft arm defining a shaft arm longitudinal axis; and an end section fixation portion extending substantially longitudinally from said shaft section fixation portion, said end section fixation portion defining a pair of end arms extending substantially away from said shaft fixation portion, each one of said end arms defining a corresponding end arm outer edge and a substantially transversely opposed end arm inner edge, said end arm inner edges of said end arms together defining a trochanter receiving recess extending therebetween, said trochanter receiving recess being configured and sized for receiving at least a selected portion of said greater trochanter, said selected portion of said greater trochanter being a prominent portion of said greater trochanter that protrudes from adjacent portions of said greater trochanter, said end arms being configured, sized and positioned such that said trochanter receiving recess substantially fittingly receives said prominent portion of said greater trochanter; said shaft section fixation portion and said end section fixation portion being configured and sized so as to be respectively securable to said femur shaft and to said greater trochanter; wherein said end arms are configured, sized and positioned so as to converge toward each other in a direction leading substantially toward said shaft arm, said end arms together forming a substantially V-shaped configuration, said V-shaped configuration being laterally asymmetrical relative to said shaft arm longitudinal axis, each of said end arms defining a corresponding end arm proximal section and a substantially longitudinally opposed end arm distal section, said end arm distal sections of said end arms merging integrally with each other at a merging location; said end arms being also configured, sized and positioned such that one of said end arms is securable to said anterior facet and another one of said end arms is securable to said lateral facet when said fixation component is operatively secured to said greater trochanter.
