An instrument comprising a body comprising a distal end spaced apart from a proximal end relative to a longitudinal axis and a handle coupling located near the proximal end, the body defining a channel miming between the distal end to the proximal end; a drive comprising a first connector located adjacent the distal end and adapted to be connected to a driven instrument, a second connector located adjacent the proximal end and adapted to be connected to a driving instrument, and a drive shaft arranged in the channel, the drive shaft coupling the second connector to the first connector; and an adjustable handle located near the distal end, the adjustable handle comprising a grip spacing apart a leading end from a trailing end along a handle axis, the leading end coupling the handle to the handle coupling, the trailing end shaped to define an impaction plate; wherein the adjustable handle is arrangeable relative to the body in a first and a second position, in the first position the leading end is arranged relative to the handle coupling such that the handle axis is offset relative to the longitudinal axis, and in the second position the leading end is arranged relative to the handle coupling such that the handle axis is parallel to the longitudinal axis.

Adjustable reamer driver and impactor, and methods of preparing said driver and impactor

A system for reaming a bone comprising: a base comprising a connector adapted to couple the base to a driver and a support surface; a first reaming member comprising: a first seating surface shaped to seat the first reaming member over the support surface, a first reaming surface adapted to ream a bone to a first diameter, and a first attachment mechanism attaching the first reaming member to the base; a second reaming member comprising: a second seating surface shaped to seat the second reaming member over the support surface, a second reaming surface adapted to ream a bone to a second diameter, and a second attachment mechanism attaching the second reaming member to the base; wherein the second diameter is larger than the first diameter.

Assemblies and kits for reaming orthopedic joints, and method of assembling reamer for said

A surgical component, a kit including the surgical component, and a surgical method. The surgical component includes a body portion. The surgical component also includes an elongate stem for inserting into an intramedullary canal of a patient. The elongate stem extends distally from the body portion. The elongate stem has a longitudinal axis; a proximal end; a distal end; and a plurality of splines located on an outer surface of the stem. The splines are circumferentially arranged around the stem. At least some of the splines are tapered such that each tapered spline is narrower at a distal part of that spline than at a part of that spline that is proximal with respect to the distal part. The surgical component further includes an elongate neck portion extending from the body portion at a non-zero angle with respect to the longitudinal axis of the stem.

Surgical component, kit and method

An orthopaedic surgical instrument for use in resecting a patient's bone is disclosed. In some embodiments, the instrument may be for single patient use and may be disposed of at the end of each surgical procedure.

Orthopaedic surgical instrument

Orthopeadic surgical instrument

An angular adjustment mechanism for a surgical instrument is described. The mechanism comprises an adjustment member () configured for rotation about a longitudinal axis (), the adjustment member comprising a plurality of pairs of facets () arranged about the longitudinal axis. Each of the plurality of pairs of facets defines a respective angled axis (B,C) at an angle (B,C) relative to the longitudinal axis. A pivoting member () is arranged to pivot about a pivot axis perpendicular to the longitudinal axis and comprises a recess () for receiving the adjustment member and engaging one pair of the plurality of pairs of facets. This provides an angular adjustment mechanism in which facets on the outside of the adjustment member engage corresponding surfaces in a recess on a pivoting member. The use of facets provides a secure connection while allowing a greater degree of angular adjustment and providing a further benefit of simple operation.

Angular adjustment mechanism, surgical alignment guide and surgical instrument assembly

Orthopaedic surgical instruments including a base trial adapted to be positioned on a proximal end of a patient's resected tibia, and a guide tower including a tower base adapted to be positioned on the base trial. A method of use is also described.

Surgical instruments and method for use in surgically preparing a tibia for implantation of a prosthetic component

Surgical instruments for use in surgically preparing a tibia for implantation of a prosthetic component

A method of surgically preparing a tibia for implantation of a tibial prosthetic component is disclosed.

Method of surgically preparing a tibia for implantation of a prosthetic component

An orthopaedic surgical instrument assembly that includes a handle and a keel punch configured to be inserted into a proximal end of a surgically-prepared tibia of a patient. The handle includes a lever configured to secure the keel punch to the handle.

Surgical instrument assemblies for use in surgically preparing a tibia for implantation of a prosthetic component

A multi-function impactor for use with an orthopaedic implant, such as a knee joint, is described. The head of the impactor has a pair of curved recesses for mating with condylar parts of a femoral implant and flat faces for mating with a tibial implant. An extended formation is also provided for use with the inter-condylar notch of the femoral implant. A v-shaped notch in the extended formation is also provided to impact a tibial insert. The impactor can be made from a single moulded plastics part.
