A medical device for preparing an elongated bone, such as a proximal femoral bone, for receiving an implant includes a patient-specific femoral guide and an elongated alignment element. The femoral guide has a patient-specific three-dimensional bone-engaging surface configured according to a preoperative plan based on a three-dimensional image model of the femoral bone to mate complementarily with the surface of the proximal femoral bone extending between the greater trochanter, the femoral neck and the femoral shaft of the proximal femur. The femoral guide includes a first guide end forming a planar guide configured for guiding a neck resection. The alignment member can be removably attached to the femoral guide and defines a reference axis for guiding a cutting tool into the femoral bone through a resected surface of the femoral neck.

Patient-specific femoral guide

A surgical kit for preparing a joint surface to receive an implant includes a patient-specific guide for a joint surface. The patient-specific guide has a patient-specific surface complementary to a surface of the joint for nesting engagement, and a guiding element oriented along a patient-specific alignment axis. The alignment axis is determined during a preoperative plan of the specific patient for implant alignment. The kit includes a guiding tool couplable to the guiding element of the patient-specific guide and a three-dimensional orientation device removably couplable the guiding tool for intra-operative calibration, such that, after calibration, the orientation device can be removably coupled to a shaft of a surgical instrument to align the shaft along the alignment axis.

Patient-specific acetabular guides and associated instruments

Disclosed is a modular trial system to select a neck length. The system may be in a hexagonal or click embodiments. A neck member may having at least a locating step with a locating step face. A head member may have at least a first groove and a second groove in an internal bore. The head member may be rotated relative to the neck member to select various trial lengths of the neck.

Adjustable modular prosthesis

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.
