ORTHOPAEDIC BROACH EXTRACTION TOOL
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.
Femoral nail with enhanced bone conforming geometry
A femoral nail includes a proximal section, a distal section remote from the proximal section, and an intermediate section disposed between the proximal section and distal section and having first and second curved portions. The first curved portion is positioned closer to the proximal section than the second curved portion. The second curved portion is curved in a first plane, and the first curved portion is curved in the first plane and a second and third plane.
Spinal implant system and method
A surgical instrument comprises a first member extending between a proximal end and a distal end configured for fixation with tissue. A second member defines a longitudinal passageway and is connected with a navigation component such that the distal end is disposable with the passageway at a selected distance from the navigation component. The navigation component is positioned relative to a sensor to communicate a signal representative of an orientation of the first member. A third member extends between a proximal end and a distal end. The third member is mountable with the first member along the orientation such that the distal end of the third member is engageable with the tissue. Systems, spinal implants, constructs and methods are disclosed.
PROXIMAL HUMERAL STABILIZATION SYSTEMS AND METHODS THEREOF
An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.
BI-SPRING SURGICAL IMPACT TOOL
Disclosed herein are bi-spring surgical impact tools and methods of use thereof. The bi-spring surgical impact tools can include a housing, a shuttle, a pinion, and first and second springs. The housing can define a cavity having a first end and a second end. The shuttle can be located within the cavity and define a plurality of indentations. The pinion can be located proximate the shuttle and have a plurality of protrusions sized to mesh with the plurality of indentations during rotation of the pinion. The first and second springs can be mechanically coupled to the housing and the shuttle. Rotation of the pinion in a first direction can translate the shuttle in a first direction towards the first end of the housing and rotation of the pinion in a second direction can translate the shuttle in a second direction towards the second end of the housing.

METHOD OF CONTROLLING INSTRUMENTATION DEPTH IN TOTAL JOINT ARTHROPLASTY
A method to guide in preparation of a bone relies on an instrument having a shaft with a working end and a stop member. The shaft is free to translate along an axis. Surgical planning data is registered to the bone to determine intra-operative coordinates of the desired axis and depth. The instrument holder is positioned by the bone so the stop member contacts the instrument holder to prevent translating beyond the desired depth. Alternatively, an arm is manipulated to align the instrument with the desired axis. The working end rests on the bone to define a linear separation to the desired depth. By proximally translating the instrument holder to contact the stop member and distally translating the instrument holder along the shaft, the stop member physically stops translating beyond the desired depth. A surgical system for performing the methods is provided; a reamer or impactor are also disclosed.
Chuck assembly for a medical device
A chuck assembly for a medical device is provided. The chuck assembly includes a mounting base structured to couple to a tool; a housing coupled to the mounting base; and a cam sleeve within the housing and movable with respect to the housing between a locked position and an unlocked position, the cam sleeve having an annular base, an arm extending from the annular base, and a cam extending laterally from the arm.
SPINAL PLATE
Spinal plates with additional features to improve the stability of the interface between the plate and the underlying bone. A bone plate may include one or more sharp ridges along the periphery of its underside. When attached to bone, the ridge digs into the bone and increases stability. A bone plate may alternatively or additionally include one or more holes for optional spikes, which may be inserted once the plate is attached to the bone. By separating the spikes and including them as an optional component, the plate may enhance stability while reducing or eliminating the chance of the spike injuring the patient. Furthermore, bone screws may incorporate alternating notches and ridges into the head of the screw. The notches and ridges may interface with a set screw, thereby preventing rotation and loosening of the screw.
