Definitions

  • the present invention relates generally to the field of orthopedics, and more particularly to trial femoral neck assembles, kits and methods for use in intraoperative trialling of hip prostheses to determine an appropriate length for the definitive femoral neck component of a prosthetic hip joint.
  • Optimal hip mechanics in hip arthroplasty is achieved through the selection of an appropriate neck length and head offset in the femoral component of the prosthetic hip implant.
  • the distance between the femoral stem component and the femoral head component establishes the requisite head offset and neck length which in turn contributes to the desired range of motion, leg length, and tension in the soft tissue at the implant site.
  • head offset In order to optimize hip mechanics, it is desirable to select the leg length with precision.
  • Femoral offset is an important clinical requirement. When offset is not restored, medialization of the femur can occur which results in impingement and possible instability. Additionally, if offset is not restored at the time of surgery, laxity of tissues can occur resulting in weakness and possible dislocation.
  • femoral stem components are offered in standard offset and high offset configurations to provide proper joint tension without affecting leg length or surgical technique.
  • Trial femoral neck components are usually designed to work with the corresponding size of broach. This requires a large inventory of trial neck components within an instrument tray. In order to reduce the inventory, it would be desirable to reduce the number of trial femoral neck components required.
  • the instrument tray would include a set of broaches of varying sizes, one trial standard offset trial femoral neck assembly and one trial high offset femoral neck assembly.
  • the invention provides a kit in which progressive neck length is accommodated within the broach. This is achieved by the provision of a femoral neck length setting projection on each size of broach that allows the neck length to be varied on the broach side of a broach/trial femoral neck assembly. This prevents the need for a different trial femoral neck component for each broach size.
  • the inventory of trial femoral neck components within the instrument tray may therefore be reduced to one trial standard offset femoral neck component and/or one trial high offset femoral neck component.
  • an adjustable trial femoral neck assembly comprising:
  • a broach attachment part comprising:
  • a bore extending inwardly from the broach facing surface and being dimensioned for receipt of a connecting element extending from a proximal surface of a broach by which the broach is connected to the broach attachment part
  • assembly further comprises:
  • a femoral head attachment part comprising:
  • a proximal portion configured for removable attachment to a trial femoral head
  • a distal portion comprising a neck
  • the connecting element is received within the bore, and a distal end of the neck engages with a proximal most surface of a femoral neck length setting projection that projects beyond the proximal surface of the broach to thereby set the distance between the proximal facing surface of the broach attachment part and a proximal end of the proximal portion of the femoral head attachment part.
  • the femoral neck length setting projection is defined by a step portion extending from a wall of the connecting element.
  • the femoral head attachment part is spring loaded such that the assembly is always in the smallest, most retracted position. This ensures that the spring is not under compression during trial reduction.
  • the broach attachment part of the trial femoral neck assembly comprises a biasing means to bias the femoral head attachment part towards the broach attachment part.
  • the biasing means may be a helical spring or a compression spring.
  • the trial femoral neck assembly is provided a standard offset femoral neck trial assembly or a high offset femoral neck trial assembly.
  • the trial femoral neck assembly is provided with a retaining feature that retains the neck assembly on the broach during trialling. This prevents disassociation of the neck from the broach. This retaining feature also prevents any inadvertent rotation of the neck assembly relative to the broach.
  • a suitable retaining feature is a live spring.
  • kits for use in trialling of a femoral head comprising a trial femoral neck assembly as herein described, and further comprising:
  • a first broach having a femoral neck length setting projection with a proximal most surface that projects beyond the proximal surface of the broach by a first distance such that when the distal end of the neck engages with the proximal most surface of the femoral neck length setting projection the neck length of the adjustable trial femoral neck assembly is set at a first distance
  • a second broach having a femoral neck length setting projection with a proximal most surface that projects beyond the proximal surface of the broach by a second distance such that when the distal end of the neck engages with the proximal most surface of the femoral neck length setting projection the neck length of the adjustable trial femoral neck assembly is set at a second distance.
  • the second broach is larger than the first broach and wherein the proximal most surface of the femoral neck length setting projection on the second broach projects further beyond the proximal surface of the broach than the proximal most surface of the femoral neck length setting projection on the first broach, such that when the trial femoral neck assembly is assembled onto the second broach the trial femoral neck assembly has a longer neck length.
  • the kit includes at least one of a standard offset femoral neck trial assembly or a high offset femoral neck trial assembly.
  • a method of selecting a femoral neck component for use in an orthopaedic joint prosthesis comprising the steps of
  • an adjustable trial femoral neck assembly comprising:
  • a broach attachment part comprising:
  • the assembly further comprises:
  • a femoral head attachment part comprising:
  • a proximal portion configured for removable attachment to a trial femoral head
  • a distal portion comprising a neck, such that when the broach attachment part of the trial femoral neck assembly is attached to the broach, the connecting element extending from the proximal surface of a broach is received within the bore, and a distal end of the neck engages with a proximal most surface of a femoral neck length setting projection that projects beyond the proximal surface of the broach to thereby set the distance between the proximal facing surface of the broach attachment part and a proximal end of the proximal portion of the femoral head attachment part,
  • a first broach having a femoral neck length setting projection with a proximal most surface that projects beyond the proximal surface of the broach by a first distance such that when the distal end of the neck engages with the proximal most surface of the femoral neck length setting projection the neck length of the adjustable trial femoral neck assembly is set at a first distance
  • a second broach having a femoral neck length setting projection with a proximal most surface that projects beyond the proximal surface of the broach by a second distance such that when the distal end of the engages with the proximal most surface of the femoral neck length setting projection the neck length of the adjustable trial femoral neck assembly is set at a second distance
  • the trial femoral neck assembly that is connected to the first broach or second broach is a standard offset femoral neck trial assembly or a high offset femoral neck trial assembly.
  • Figure 1 shows a schematic of a trial femoral neck assembly according to the invention.
  • FIG. 1 A schematic of an exemplary adjustable trial femoral neck assembly 10 is shown in Figure 1.
  • the trial femoral neck assembly includes a broach attachment part 12 and a femoral head attachment part 14.
  • the broach attachment part 12 includes a proximally facing surface 16, a broach facing surface 18, and a bore 20 that extends inwardly from the broach facing surface 18.
  • the bore 20 is dimensioned for receipt of a connecting element 22 extending from a proximal surface 24 of a broach 25.
  • the broach is connected to the broach attachment part 12 of the assembly via this connecting element.
  • the femoral neck length setting projection 26, provided on the proximal surface of the broach, is defined by a stepped portion which is integral with, and extends in a medial direction from the connecting element 22. It is however envisaged that the femoral neck length setting projection 26 may be provided as a discrete element that is separate from the connecting element 22. For example, the femoral neck length setting projection 26 may be provided as a post that is spaced apart medially from the connecting element 22.
  • the femoral neck length setting projection 26 includes a proximal most surface 28 onto which at least a portion of the distal end 34 of the femoral head attachment portion will be engage.
  • the femoral head attachment part 14 includes a proximal portion 30 configured for removable attachment to a trial femoral head, and a distal portion comprising a neck 32.
  • a least a portion of the distal end 34 of the neck 32 will engage at least a portion of the proximal most surface 28 of the femoral neck length setting projection 26. As shown in FIG. 1, a comer of the distal end 34 of the neck 32 will seat on the proximal most surface 28 of the connecting element 22.
  • Broaches are used during hip arthroplasty to replicate the definitive femoral stem.
  • Each incremental size of broach that is used in conjunction with the inventive trial femoral neck assembly as herein described includes a femoral neck length setting projection 26 that projects a different extent beyond the proximal surface 24 of the broach 25.
  • the femoral neck length setting projection 26 extends a greater extent beyond the proximal surface of the broach 24. This results in an increase in neck length with increasing sizes of broach because with each incremental size of broach the neck 32 of the femoral head attachment 14 part will not sit as deep within the broach attachment part 12.
  • the femoral neck trial will have a longer neck length because the proximal portion 36 of the femoral head attachment part will be forced to sit more proud of the proximal facing surface of the broach attachment part 16. That is, the distance di represented in FIG.l will increase.
  • a spring 38 connects the broach attachment portion 12 and the femoral head attachment part 14.
  • the spring biases the femoral head attachment part 14 towards the broach attachment portion 12. This ensures that the trial femoral neck assembly is always in the smallest, most retracted position, thereby ensuring that the spring is not under compression during trial reduction.
  • the trial femoral neck assembly is provided with a retaining feature 40 that retains the neck assembly on the broach during trialling. This prevents disassociation of the neck from the broach. This retaining feature also prevents any inadvertent rotation of the neck assembly relative to the broach.
  • a suitable retaining feature is a live spring.

Abstract

L'invention concerne un kit dans lequel la longueur de col progressive est adaaptée à l'intérieur de la broche (25). On parvient à ce résultat en fournissant une projection (26) de réglage de longueur de col fémoral sur chaque taille de broche, qui permet de modifier la longueur du col du côté broche d'un ensemble col fémoral d'essai/broche. On supprime ainsi la nécessité d'utiliser un composant de col fémoral d'essai différent pour chaque taille de broche. Le nombre de composants du col fémoral d'essai au sein du plateau à instruments peut ainsi être réduit à un composant de col fémoral d'essai à déport standard et/ou à un composant de col fémoral d'essai à déport élevé.
