Abstract: Devices and methods provided for joint arthroscopy contemplate and enable the provision of patient specific instruments (PSI). The devices and anatomical features of a patient are rendered adjustable by the provision of guide elements and feature to account for and enable repositioning of the anatomical features during surgery. Where the joint arthroscopy involves ankle arthroplasty, a PSI system includes a tibial PSI operable to be coupled to a tibia and a talar PSI operable to be coupled to a talus. Pins pass through the tibial PSI into the tibia and through the talar PSI into the talus. The tibia and talus are aligned based on the tibial PSI, the talar PSI, the pins, and optionally a connection guide operable to receive, or be coupled to, the pins. The tibial PSI and the talar PSI allow for the transfer of pre-operative planning to intra-operative procedures.

Abstract: An apparatus and a method are provided for a patient-specific instrument guide for arthroplasty or other operations on bone tissue, capable of limiting bone cuts, achieving optimal implant positioning, and providing improved stability of implants. The patient-specific instrument guide comprises a body that includes a bone contact surface configured to contact a bone surface of a patient. The body is configured to be 3D printed according to medical imaging of a patient's anatomy, such that the bone contact surface optimally contacts the surface of the patient's bone. The body includes one or more guide slots that each slidably receives a cutting guide. The cutting guides are configured to receive a saw blade during bone cutting. The cutting guides may be oriented to guide cutting a talus or a tibia during a total ankle arthroplasty surgery.

Abstract: Devices and methods provided for joint arthroscopy contemplate and enable the provision of patient specific instruments (PSI). The devices and anatomical features of a patient are rendered adjustable by the provision of conforming surfaces and support elements to account for and enable repositioning of the anatomical features during surgery. Where the joint arthroscopy involves shoulder arthroplasty, a PSI system includes at least one shoulder PSI operable to be positioned on a bone in a shoulder in the patient. The at least one shoulder PSI allow for the transfer of preoperative planning to intra-operative procedures. The at least one shoulder PSI may be virtually designed as a model based on scan data of the bone in the shoulder of the patient. The at least one shoulder PSI may be fabricated based on the virtually-designed at least one shoulder PSI model.

Abstract: A ball holder for punt training has a base, a length-adjustable post, a support arm, an intermediary connector, and a gripper. The ball holder is designed to be used in a set of two ball holders are positioned on opposite sides of a ball. Thus positioned, the two ball holders retain the ball at an optimal height for being punted. One end of the length-adjustable post is mounted to the base, such that the length-adjustable post is oriented perpendicular to the base. The support arm is laterally mounted onto the length-adjustable post to form a cantilever that retains the ball in a position offset from the length-adjustable post. The intermediary connector is a flexible fastening device that is connected in between the support arm and the gripper. Accordingly, the intermediary connector enables the gripper to be moved out of the way when an athlete punts the ball.
