A total hip femoral prosthesis provides a shortened neck and more proximal coating level. Additionally, a means for strengthening the neck may be incorporated to increase stress transfer to the native bone. A method for reducing potential impingement that results from a high neck resection level includes instrumentation for cutting chamfered surfaces into the bone surrounding the proximal end of the implant. Instrumentation and methods of creating chamfered cuts are disclosed.

Active compression devices, methods of assembly and methods of use are disclosed. A bone fixation device may include a first member, a second member shaped to engage the first member, and at least one deformable member. A bone fusion device including a female member with a proximal and distal end, a male member with a proximal and distal end, and at least one elastic element positioned between the female member and the male member. A bone plating device including a first member, a second member shaped to engage the first member, and at least one deformable member positioned between the first member and the second member. Methods of assembling and using the bone fixation devices, bone fusion devices, and bone plating devices are also disclosed.

This positioning system (100) for a bone resecting instrumentation comprising a resection driver (2), comprises at least one of a gyroscopic sensor (8) integral in motion with the resection driver (2) and adapted to sense a deviation angle (¸) with respect to a reference direction (X), and at least one positioning marker (12; 140) marking a fixed position on the reference direction (X), and a depth sensor (10; 18) integral in motion with the resection driver (2), for detecting a resection depth (d) based on the relative longitudinal positions of the positioning marker (12; 140) and the depth sensor (10). The invention also concerns a positioning kit including such a positioning system and a separate electronic device.

The invention relates to a surgical tool (10) for reaming the diaphyseal canal of long bones, in particular of the femur, humerus, or tibia, in order to insert a intramedullary rod. The modular reaming head includes: a central core (60) and a peripheral bushing (24) that is coaxial to said central core (60) and connected via a plurality of vanes (41a-41e) defining a plurality of axial openings (45a-45e) connecting a front surface (12) of the tool (10) to a rear surface (11) of the tool (10), and teeth (26a-26e) on the outer surface of said peripheral bushing (24). The openings allow material to pass toward the rear when the tool advances within the diaphyseal canal, minimizing pressure and friction, resulting in a positive effect on the rate of clinical complications. The tool is preferably made using the metal injection molding (MIM) technique in order to reduce production costs and enable the one-time use thereof. The reaming head of the invention can be perfectly combined with composite or metal drive shafts.

Provided is a method and device for shaping a greater tuberosity of a humerus in preparing for receiving a prosthetic humeral head. The device shaves bone from the greater tuberosity such that the greater tuberosity is not resected or completely removed.

Humeral head shaping device and method

An orthopedic driver is provided that includes an elongate tubular body and an indicator assembly. The indicator assembly has a housing that has at least one opening and a visual indicator disposed in the at least one opening. The visual indicator is configured to be coupled with a guide pin such that lateral movement of the elongate tubular body relative to the guide pin causes the visual indicator to move between a flush or recessed configuration within the housing and an extended configuration. In the extended configuration, the visual indicator extends outward of an outer surface of the housing. The flush or recessed configuration corresponds to alignment of the guide pin relative to the elongate tubular body and the extended configuration corresponds to misalignment of the guide pin relative to the elongate tubular body.

Implants, device, systems and methods for replacing an articulation surface in a joint, for example, shoulder prostheses with stemless humeral components or stemmed humeral components. Methods for using the shoulder prostheses with stemless humeral components or stemmed humeral components are also disclosed.

A bone reamer includes a shaft having a first and a second end. The second end is configured to connect to a rotating power source. A head of the reamer includes a rear face connected to the first end of the shaft, a cutting face on an opposing side of the head relative to the rear face, and a perimeter portion having an inner perimeter diameter and an outer perimeter diameter. The outer perimeter diameter defines outer boundaries of the rear face and the cutting face. A blade member of the reamer is disposed upon the cutting face and extends at least across the inner perimeter diameter of the perimeter portion. A center drill bit is disposed on the cutting face. The drill bit and cutting blade are concentric about a center axis of the reamer.
