Abstract: An adjustable reaming device can include a proximal reamer and a positionable element. The positionable element removably attaches to the proximal reamer at one of a plurality of discrete longitudinal locations along the proximal reamer. A distal end of the positionable element forms a stop, which can contact a proximal end of a distal reamer and thereby limit distal motion of the proximal reamer with respect to the distal reamer. When the distal reamer is in contact with the positionable element, the distal reamer and proximal reamer are longitudinally offset by a one of a plurality of specified offsets. In some examples, the specified offsets correspond to a plurality of specified, discrete lengths for which implantable femoral stems are available.

Abstract: Templating software can determine and visually depict the location and size of cuts in a trochanteric osteotomy, including an extended trochanteric osteotomy. The software can also calculate the size and area of fixation for a newly implanted prosthesis, based upon which the new prosthesis that will be implanted in a particular patient can be selected. Additionally, an adjustable cut guide can stabilize and guide the cuts during the procedure.

Abstract: An apparatus can include an acetabular cup, and a connection member that can be mounted to the acetabular cup such as near a rim edge of the acetabular cup. The connection member can include an attachment section that can be configured to receive an attachment from an inserter. The attachment section can be configured to permit the inserter to be attached to the connection member in two or more different orientations relative to the connection member.

Abstract: Hip replacement surgery (hip arthroplasty) includes implantation of a distal stem into a femur of a patient, and implantation of a proximal body to connect to the distal stem. A practitioner uses a “trial” or “provisional” to determine a suitable size and configuration for the implantable proximal body, then selects a suitable proximal body from a set of differently sized and shaped proximal bodies. The trial adjusts discretely, as opposed to continuously, and has discrete settings that correspond to the sizes and configurations available in the set of implantable proximal bodies. In some examples, the trials are provided as a kit of parts, where each part in the kit is adjustable for height (i.e., the length of the femur). The parts in the kit can have different, fixed, values for offset (i.e., the lateral distance of the femur to the center of the femoral head in the acetabulum).

Abstract: An orthopedic implant inserter is provided with removable jaws. The jaws are connected to handles of the inserter by retainers. Each retainer includes a shaft and a latch. The shaft is configured to be received within mounting bores of a jaw and the associated handle. The latch is connected to the shaft and movable between a release configuration and a retaining configuration. In the release configuration, the shaft is removable from the mounting bores and the jaw is thereby removable from the associated handle. In the retaining configuration, the shaft is secured within the mounting bores and the jaw is thereby secured to the associated handle.

Abstract: An orthopaedic cutting instrument and associated methods are presented.

Abstract: A method and apparatus for performing a minimally invasive total hip arthroplasty including an acetabular cup inserter is provided. The cup inserter is utilized for securing a prosthetic acetabular component thereto for implantation into a hip joint. The acetabular cup inserter includes a frame having an offset frame leg to allow for placement of an acetabular cup in the correct anteversion and abduction without interference from soft tissue.

Abstract: An osteotomy guide for indicating the femoral neck resection on a femur and its method of use are presented. The osteotomy guide includes an indexing feature for aligning the guide with an anatomic landmark and a resection guide for indicating the resection relative to the indexing feature.

Abstract: An orthopaedic cutting instrument and associated methods are presented.

Abstract: An apparatus includes a surgical retractor and a light conduit releasably coupled to the surgical retractor. In an alternative embodiment, a method of illuminating a surgical cavity includes expanding the cavity with a plurality of surgical retractors, transmitting light from a remote source the to the cavity through a light conduit of at least one of the retractors, focusing a first amount of the light into a first portion of the cavity via the retractor including the conduit, and dispersing a second amount of the light into a second portion of the cavity via substantially lustrous surfaces of the retractors.

Abstract: An apparatus for illuminated retraction of a surgical cavity includes a surgical retractor having a generally tubular body forming a cannula insertable into a surgical cavity. The cannula has an inner surface defining a passage from a first end to a second end and an outer surface for abutting the margins of the surgical cavity. A light conduit includes a light emitting end for positioning adjacent to the passage to direct light into the passage.

Abstract: An apparatus includes a substantially pliable sheet-like member, a surgical retractor, and a substantially elastic coupling extending between the sheet-like member and the retractor. A method for expanding a surgical cavity in a patient includes positioning the patient on a substantially pliable sheet-like member, positioning a surgical retractor in the cavity, extending a substantially elastic coupling between the sheet-like member and the retractor, and tensioning the coupling.

Abstract: A method and apparatus for performing a minimally invasive total hip arthroplasty. An approximately 3.75-5 centimeter (1.5-2 inch) anterior incision is made and the femoral neck is severed from the femoral shaft and removed through the anterior incision. The acetabulum is prepared for receiving an acetabular cup through the anterior incision, and the acetabular cup is placed into the acetabulum through the anterior incision. In one exemplary embodiment, a posterior incision of approximately 2-3 centimeters (0.8-1.2 inches) is generally aligned with the axis of the femoral shaft and provides access to the femoral shaft. In this embodiment, Preparation of the femoral shaft including the reaming and rasping thereof is performed through the posterior incision, and the femoral stem is inserted through the posterior incision for implantation in the femur. In an alternative embodiment, preparation of the femur is effected through the anterior incision, with the operative hip placed in hyperextension.

Abstract: An improved constrained socket for use with an orthopedic implant for replacing a ball-and-socket joint. The constrained socket includes cuts extending from the opening of the socket generally toward the articular region thereof. Petals are formed between adjacent cuts in the socket. The socket further includes an annular expansion cutout, with the aforementioned cuts terminating therein. The socket does not include cuts on the primary articular surface, but nevertheless has a relatively low assembly force to allow assembly of the ball-and-socket joint during a surgical procedure. The relatively low assembly force of the constrained socket of the current disclosure is due in part to the annular expansion cutout which allows sufficient outward flexure of the petals to allow insertion of the ball of the ball-and-socket joint.
