A trial neck for hip surgery and a method of attaching a trial neck to a femoral canal implement. The trial neck includes a body portion including a bore for receiving a proximal end of a femoral canal implement. The trial neck also includes an elongate neck extending from the body portion. The trial neck further includes a locking mechanism comprising a lever. The lever has a first end. The lever also has a second end. The lever further has an engagement surface. 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.

A surgical device () for extraction of a prosthetic component from a patient during surgery. The surgical device comprises a first component () having a female coupling portion at a first end, and a second end configured to be connected to one of a prosthetic component or a surgical extraction instrument. The first component further includes a retainer. The surgical device further comprises a second component () with a first end defining a male coupling portion, a stem () extending from the male coupling portion, and a second end configured to be connected to the other of the prosthetic component or the surgical extraction instrument. The male coupling portion of the second component is configured to be disposed within the female coupling portion of the first component and retained within the female coupling portion by the retainer, with the stem of the second component extending away from the female coupling portion of the first component. The male coupling portion of the second component and the retainer of the first component are configured such that the male coupling portion is held in the female coupling portion while allowing articulation of the first component relative to the second component. The first and second components form an articulating joint allowing a user to connect the surgical extraction instrument to the prosthetic component in a patient, articulate a portion of the surgical extraction instrument which resides external from the operating site, and transfer extraction forces to enable removal of the prosthetic component from the patient.

The invention provides a surgical device for performing a controlled resection of the neck of a femur during a hip replacement procedure. The surgical device comprises a body portion having: a frame comprising an aperture dimension for receipt of a femoral head of the femur to position the body portion with respect to a centre of the femoral head; a resection guide for indicating a position of a resection plane on the femoral neck, and an arm extending between the frame and the resection guide. The body portion includes a linear alignment surface for alignment with a femoral shaft axis of the femur while the frame is mounted on the anterior or posterior aspect of the femoral head.

A method of operating a surgical instrument for use in a knee replacement surgical procedure includes assembling a ligament balancer instrument assembly by selecting from a number of differently sized tibial paddles and femoral paddles and thereafter securing the assembled ligament balancer instrument assembly to a distraction instrument.

Methods of operating a surgical instrument and performing a surgical procedure to balance a patient's knee

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 neighboring 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.

Surgical instrument and method for performing an orthopaedic surgical procedure

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.

Impactor

The invention provides an osteotome which includes a curved guide member extending distally from its medial side. 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.
