A tool holder for a modular tool is provided in which the tool holder may be releasably coupled to a working part such as a rasp, reamer or impactor. The coupling comprises a slot closed at both extremities, and widening to an entry aperture at one extremity, into which a keyed element of the tool may be inserted, and slid to the opposite extremity of the slot. The modular tool defines a securing pin channel through its body, terminating at the entry aperture such that a securing pin inserted into the channel block the entry aperture and locks the keyed element of the tool in place once inserted.

Embodiments of the invention comprise a blade that has a gripping portion, a transition portion and a distal portion that may have a cutting edge. The gripping portion may be V-shaped in cross-section, or, more generally, not lying in a single plane. Some embodiments are straight along a longitudinal direction. Embodiments may comprise a transition portion that is complex having sub-regions, or a distal portion having a cross-sectional shape that is curved or V-shaped, or a distal portion having a tip of a different material. Other embodiments have a shape that follows a longitudinal path that is curved either concavely or convexly or both. Distal tip design parameters for good cutting properties are discussed.

Various implementations include a positioning device of a surgical instrument for hip arthroplasty surgery that includes an arched structure having a first and a second end, wherein the first end can be positioned inside a patient a gripping element located at the second end of the arched structure, a surgical instrument that can be coupled to the gripping element at a seat made in this gripping element, and a positioning and fixing head arranged at the first end of the arched structure and having connection means. The connection means of the positioning and fixing head face the gripping element to couple with a stem that can be inserted into a patient's femoral canal.

The present invention relates to a method of treating a hip joint of a human patient, the hip joint comprising an acetabulum, the acetabulum being a part of the pelvic bone, and a caput femur, the caput femur being the proximal part of the femoral bone, said method comprising the steps of: cutting the skin of the human patient, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area, said hole passing through the pelvic bone and into the hip joint of the human patient, and performing an action in the hip joint, through said hole in the pelvic bone.

A trial neck (30) and a method for trialling a neck of an orthopedic implant in a hip replacement procedure. The method includes inserting a broach (10) into a medullary canal of a femur and connecting a distal end of a trial neck to a proximal end (12) of the broach. The trial neck includes a proximal end connectable to a trial head. The trial neck includes a body portion extending along a neck axis (5) of the trial neck between the distal end and the proximal end. The proximal end includes a male connector for connection to a corresponding female connector of a trial head. The male connector includes a plurality of connection members (34A, 34B) extending parallel to the neck axis. The connection members are separated by one or more elongate slots (50) including at least one kink (52) forming an interlock between the connection members separated by that slot. The connection members are resiliently deflectable.

An apparatus, system, and method for extracting an orthopaedic broach from a bone of a patient comprises an orthopaedic broach extraction tool having a pair of jaws that are operable to secure the orthopaedic broach extraction tool to the orthopaedic broach. Once secured, the orthopaedic broach extraction tool can be used to facilitate extraction of the orthopaedic broach from the patient's bone using, for example, a reverse impaction tool.

A prosthesis including a hemiarthroplasty cup including an inner surface shaped and sized to accommodate a reamed or unreamed femoral head outer surface, and an outer surface shaped and sized to accommodate a reamed or unreamed acetabulum outer surface of an acetabulum socket, wherein the hemiarthroplasty cup is configured to maintain allowance of articulation of the femoral head outer surface and the acetabulum socket relative to the hemiarthroplasty cup after implantation.

A reamer device is used in the preparation of the fibula prior to the placement of an intramedullary nail. The reamer device features one or more indicating grooves on its cutting edges. These grooves can be visualized radiographically during reaming to confirm depth for the placement of syndesmotic implants through the intramedullary nail.

The present invention relates to a guide for positioning a resurfacing head implant into the appropriate position and angles on the femur bone. The present invention therefore provides a guide system for an implantable device (e.g. a resurfacing head implant), said guide system comprising a first component arranged to act as a clamp and a second component arranged to interact with the first component to prevent movement of said first component when clamped.

A system and method for improving installation of a prosthesis. Devices include prosthesis installation tools, prosthesis assembly tools, site preparation systems, and improved power tools used in implant site preparation, the tools including a secondary motion that preferably includes an ultrasonic vibration.
