A system is provided for preparing prosthetic hip implantation. The system includes a first broach, a second broach, and a trial neck having a body portion and a neck portion. A proximal end of the first broach comprises a first base having a first maximum area. The body portion can be releasably coupled to the proximal end of the first broach so as to define a first offset between a medial end of the neck portion and a longitudinal axis of the first broach, or releasably coupled to the proximal end of the second broach so as to define a second offset between the medial end of the neck portion and a longitudinal axis of the second broach. The first offset is smaller than the second offset.

An intramedullary pin includes a main body having a proximal boundary and a distal boundary; a curved extension having a degree of curvature of at least 1, the curved extension being in direct contact with the distal boundary; a distal cap having a cylindrical portion and a rounded portion, the cylindrical portion being in direct contact with the curved extension; a grip element having at least one contour, the grip element being in direct contact with the proximal boundary; and a proximal cap having a flat surface, the proximal cap being in direct contact with the grip element. Also disclosed is a clamp that includes a handle, two blades, a pivot, and a plurality of grasping elements including a notch, at least one protrusion, and a groove, where one or more grasping elements have a contour that is structurally complementary to the grip element in the intramedullary pin. A method of immobilizing a bone fracture using the intramedullary pin and/or clamp is also disclosed.

This disclosure relates to a bone tamp and a corresponding method including the bone tamp sliding over a guide wire projecting from a digit of a foot and protruding from an interphalangeal implant.

A device for forcibly inserting a surgical implant into a receiving bone (4), by impaction, comprising an impactor (10) which exerts an impact force on the implant and is associated with at least one sensor (12). The sensor (12) measures the deformation of the impactor (10), and provides a measurement signal representing the temporal variation of the deformation during an impact. The sensor (12) is connected to a processing unit (30) configured to calculate, on the basis of the temporal variation of the deformation of the impactor (10) during the impact, an indicator representative of the level of contact between the implant and the receiving bone (4).

An implant and method for fixation of long bones. The implant provides rotational, longitudinal, and bending stability. The implant comprises one or more elongated members that span the intramedullary cavity of a long bone, a distal tip that expands radially relative to the long axis of the implant, and a locking mechanism at the proximal end of the implant.

The present invention relates to a method for fixing an intramedullary cavity nail for the treatment of unstable trochanteric fractures and to a targeting device for use in performing the steps of said method. According to the method, a recess (16) for a femur neck screw (8) for fixing the cavity nail (2) is provided in at least the lateral cortex of the femoral shaft (FS) in close distal proximity to a hole (9) for the femur neck screw such that bone fragment(s) located distally of the fracture and bone fragment(s) located proximally of the fracture relatively seen can be displaced towards each other. A targeting head (5) of the targeting device (1) is configured with a targeting bore (14) which is alignable with a point on the femoral shaft (FS) in close distal proximity to the hole (9) for the femur neck screw (8) for use in providing at said point, said recess (16) for the femur neck screw.

A method of implanting a medical implant comprises the steps of reaming a tapered bore to a first depth and a counter bore, coaxial to the tapered bore, to a second depth less than the first depth in a long bone. The counter bore has a larger diameter than the tapered bore. The method further includes inserting a medical implant into the tapered bore and counter bore. The medical implant includes a stem and a collar disposed around a portion of the stem. Inserting the medical implant include fully seating a portion of the stem into the tapered bore to form a press-fit between the stem and the long bone. The collar may be moved into the counter bore to a depth less than the second depth.

A device for forcefully inserting a surgical implant in a recipient bone by impaction, comprising an impactor (10) that exerts an impaction force on the implant and is associated with at least one sensor (12). The sensor (12) measures a value from among the exerted impaction force and the deformation of the impactor (10) and provides a measurement signal representing the temporal variation of said value during an impact. The sensor (12) is connected to a processing unit (30) that is configured to compute, on the basis of the temporal variation of said value during the impact, an indicator representing the level of contact between the implant and the recipient bone. The indicator corresponds to the duration separating the instant corresponding to the first maximum amplitude peak of the measurement signal from the instant corresponding to the second maximum amplitude peak of the measurement signal. The implant can be a femoral rod (2).

A rotational correction system includes an implant having first and second sections, the implant having a rotatable permanent magnet disposed in a housing of the first section, the rotatable permanent magnet mechanically connected to a nut operatively coupled to the second section. A keyed portion is interposed between the nut and one or more non-linear grooves disposed on an inner surface of the housing. An external adjustment device having at least one rotatable magnet configured to rotate the rotatable permanent magnet of the implant is part of the system. Rotation of the rotatable permanent magnet of the implant in a first direction effectuates a clockwise change in the rotational orientation of the first section relative to the second section and rotation of the rotatable permanent magnet of the implant in a second direction effectuates a counter-clockwise change in the rotational orientation of the first section relative to the second section.
