Abstract: The invention provides a reamer handle comprising: a shank having a distal tool coupling end adapted to releasably couple to a part of a surgical tool and a proximal end; a retractable catch which is linearly displaceable along the shank between a non-retracted position in which the catch captures the surgical tool within the distal tool coupling end of the tool holder and a retracted position in which the catch enables the tool to be released from the distal tool coupling end; a biasing member configured to bias the catch in the non-retracted position; and a sleeve extending along the shank. The sleeve comprises: a distally located catch contacting portion and a proximally located handle portion for manually displacing the sleeve relative to the shank such that displacement of the catch contacting portion moves the retractable catch between the non-retracted position and the retracted position to enable capture and release of the tool from the tool holder.

Abstract: A surgical rotational cutting tool, a surgical kit and a method of preparing a femur to receive a stem of a femoral prosthetic. The tool includes a longitudinal axis and a shaft extending along the longitudinal axis, which has a proximal end and a distal end. The tool also includes a head located at the distal end of the shaft. The head includes a pointed distal tip, a bone contacting outer surface having a portion which curves inwards toward the longitudinal axis as it approaches the tip, and a plurality of flutes. The edges of distal parts of neighbouring pairs of the flutes meet to define a plurality of cutting edges which extend proximally from the pointed distal tip. A proximal part of each flute extends proximally across the curved portion.

Abstract: The invention provides an impactor for transmitting an assembly force to a component of an orthopaedic implant. The impactor has first and second telescoping parts which are biased apart by means of a main spring. The main spring is compressed when an assembly force is applied to the parts. An indicator is latched against movement until it is released when the extent of the compression of the main spring by the application of an assembly force exceeds a threshold. The indicator then moves to provide the user with an indication that a minimum assembly force has been applied.

Abstract: A trial neck (10) for hip surgery and a method of attaching the trial neck to a femoral canal implement (60). The trial neck includes a body portion (4) including a bore (8) for receiving a proximal end (64) of the femoral canal implement. The trial neck also includes an elongate neck (2) extending from the body portion. The trial neck further includes a locking mechanism comprising a lever (20). The lever has a first end (24). The lever also has a second end (22). The lever further has an engagement surface (26). The second end of the lever is actuable to urge the engagement surface against the proximal end of the femoral canal implement to secure the proximal end of the femoral canal implement within the bore.

Abstract: An adjustable trial neck (100) and method of use are described. The adjustable trial neck includes a body (102), a first part (104), and a second part (106). A first adjustment mechanism is actuable by a first drive (118) which presents a first external interface (116) for a tool and which is operable by a user using the tool to translate the first part relative to the body to adjust the neck length. A second adjustment mechanism is actuable by a second drive (124) which presents a second external interface (122) for a tool and which is operable by a user using the tool to translate the second part relative to the body to adjust the neck offset.

Abstract: The invention provides an osteotome (10, 100, 200) which includes a curved guide member (14, 114, 214) extending distally from its medial side (36, 136, 236). This curved guide member interfaces with the medial curvature of the femoral canal. The guide member guides the osteotome using the internal bone geometry of the femoral canal instead of relying on external anatomical landmarks.

Abstract: An orthopaedic joint prosthesis assembly includes a head part of an orthopaedic joint prosthesis component and an alignment guide. The head part has a spherical bearing surface for articulation with a corresponding joint surface, and an assembly surface having a first bore formed in it for receiving a spigot on another part of the orthopaedic joint prosthesis. The bore has a first axis that extends perpendicular to the assembly surface. There is a discontinuity at an interface between the bearing surface and the assembly surface, and the assembly surface is arranged on a plane which is parallel to, or contains, a plane which is defined by the opening to the bore in the head part when the head part is viewed from one side in cross-section. The alignment guide has an axial portion and an arm extending from the axial portion. The arm includes a distal portion which is configured to engage the assembly surface of the head part, with the axial portion defining a second axis and being arranged to engage the bearing surface of the head part when the head part is mounted within the guide such an impaction force applied along the second axis is directed along the first axis.
