Abstract:

An assembly tool comprises in an assembled configuration a proximal implant fastener, a distal implant fastener, and a compression member. The assembly tool is operable to hold in the assembled configuration a proximal implant partially engageable with a distal implant during implantation and axial impaction. Axial impaction is exerted through the compression member of the assembly tool. The assembly tool is also operable to securely lock the tapers of proximal and distal implants after impaction by rotating the compression member.

US Classification:

623 2328, 623 2016, 623 2242

Abstract:

An implant for a hip can include a lateral augment adapted to be coupled to a lateral side of a femoral body implant. The lateral augment can include a body portion having a first surface, a second surface opposite the first surface, and a protrusion extending from the second surface. The protrusion can have a shape adapted to mate with a complimentary shaped recess formed in the lateral side of the femoral body implant. An aperture can be positioned in the body portion and extend through the protrusion. A fastener can be received through the aperture and adapted to be threadably secured to the lateral bore. The fastener can be configured to have a length sufficient to pass through a portion of a greater trochanter for securing the portion of the greater trochanter and the lateral augment to the femoral body implant.

Abstract:

A patient-specific acetabular resection guide includes a dome-shaped surface bounded by a periphery. The dome-shaped surface is a three-dimensional patient-specific surface designed to anatomically match and be received into an acetabulum of the patient, based on a three-dimensional image of a hip joint of the patient reconstructed from a medical scan of the hip joint. The resection guide includes a plurality of guiding formations defined on the resection guide and having patient-specific shapes and orientations for guiding corresponding osteotomies relative to the acetabulum for correcting hip dysplasia.

US Classification:

606 99

Abstract:

A method of implanting a prosthetic component is disclosed that includes attaching a guide rod to the prosthetic component, removably coupling the guide rod to a shaft extending from a handle, and positioning the prosthetic component in an anatomical feature. The method also includes impacting an impaction portion of the handle and uncoupling the guide rod from the shaft, leaving the guide rod attached to the prosthetic component. The method further includes positioning a reamer over the guide rod to create a reamed opening in the anatomical feature.

US Classification:

623 2211, 606 91

Abstract:

An acetabular device includes a patient-specific acetabular alignment guide including a bone engagement surface. The bone engagement surface has a first portion configured and shaped to be conforming and complementary to an acetabular rim surface and a second portion configured and shaped to be conforming and complementary to a periacetabular area of an acetabulum of a patient. The acetabular alignment guide includes a plurality of guiding formations extending through the second portion for guiding a plurality of alignment pins therethrough. The bone engagement surface and the plurality of guiding formations are prepared from a three-dimensional model of the acetabulum of the specific patient reconstructed pre-operatively from a scan of the patient.

US Classification:

606 91, 623 2223

Abstract:

A method for preparing a joint surface of a patient for an implant, such as, for example, an acetabular implant for a hip joint. According to the method, a patient-specific guide is attached to a complementary joint surface of the patient. The patient-specific guide includes a guiding element oriented along a patient-specific alignment axis. The alignment axis is determined during a preoperative plan of the patient for implant alignment. A shaft of a guiding tool is removably coupled to the guiding element of the guide. A three-dimensional orientation device is removably attached to the shaft of the guiding tool. A position of a bubble of the orientation device is marked with a mark on an outer transparent surface of the orientation device while the guiding tool is oriented along the alignment axis. The marked orientation device can be used for aligning other instruments during the procedure.
