Abstract: A kit for use in arthroplasty. The kit including a shell which has a shell locking section. The kit further including a liner adapted to be inserted into the shell. The liner includes an inner surface and an outer surface, wherein the inner surface is generally concave. The outer surface is adapted to engage the shell, and includes a liner locking section and a curved section. The curved section has a radius. The shell locking section and the liner locking section are adapted to engage one another. The shell locking section and the liner locking section are self-locking tapers. The curved section extends tangentially from the liner locking section at a first transition point.

Abstract: An orthopaedic surgical instrument system for use in preparing a patient's bone is disclosed. The surgical instrument includes a cutting guide block configured to be secured to a surgically-prepared surface of the patient's bone, and a cutting tool to be used in conjunction with the cutting guide block to resect a section of the patient's bone. A method of performing an orthopaedic surgery is also disclosed.

Abstract: Methods for performing orthopaedic surgical procedures using a handheld scanner are disclosed. The methods include, generally, performing one or more intra-operative scans using a handheld scanner, generating scan data from the intra-operatives scans, and comparing the scan data to a surgical plan. The scan data and other feedback data are used to validate the position and orientation of orthopaedic prosthetic component implanted in a body of the patient.

Abstract: A method of surgically preparing a proximal end of a tibia includes inserting an intramedullary orthopaedic surgical instrument into a medullary canal of the tibia, securing an attachment device to the intramedullary orthopaedic surgical instrument, attaching a cutting block to the attachment device, resecting the proximal end of the tibia using the cutting block to form a surgically-prepared surface, positioning a tibial base trial on the surgically-prepared surface, and inserting a keel punch through a slot defined in the tibial base trial and into the surgically-prepared surface of the tibia.
