摘要:
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.

A surgical access system includes a connector including an arm, a coupling element, a rod, and a ridged slider. The arm includes first and second notched sections disposed in opposed lateral sides thereof. The coupling element includes a body section defining an opening therethrough, and opposed tabs protruding therefrom that are configured to receive the second notched section therebetween such that the arm is pivotably coupled to the coupling element. The rod includes a shaft having a plurality of angled grooves defined partially along a length thereof. The rod extends through the opening of the coupling element and the first notched section of the arm. The ridged slider includes a first surface having a plurality of ridges extending along a partial length thereof. The ridged slider extends through the coupling element with the plurality of ridges operably engaged with the plurality of angled grooves of the rod.
摘要:
Set suitable for use in a bone-shortening osteotomy of a predetermined distance, the set comprising: an implant (1) with threaded holes (8); an accessory (2) with successively a first segment (5), a second segment (6) and a third segment (7); wherein the first segment comprises first threaded holes (9) and wherein the third segment comprises second threaded holes (9), and wherein the second segment comprises two guides (10) which are each adapted to guide a saw blade (17) so that the osteotomy of predeter mined distance (d) can be performed via the two guides.

The invention comprises a method for fixating bones in the foot by aligning the bones in their desired position, inserting a screw in the aligned bones, inserting at least one transverse element near the head or tip of the screw, and tightening the screw to compress the bones. The screw comprises a shaft having first and second ends with spirally wound screw threads beginning near the first end and extending along the shaft. Advantageously, the screw is cannulated and screw threads are formed on an interior surface of the cannulation. Illustratively, the transverse elements may be staples, open-ended washers, or open-ended nuts. Reduction instruments and drill guides used in the invention are also disclosed.

A bone plate kit may be provided for a foot or ankle orthopedic procedure, such as a lapidus procedure. In some examples, the bone plate kit includes a sterile container that holds multiple unicortical bone plate fasteners and one or more bone plates. For example, the kit may contain two bone plates configured to be used together during a tarsal-metatarsal fusion procedure. Each of the two bone plates may be configured to span different regions of a tarsal-metatarsal joint. The unicortical bone plate fasteners can be used to secure the two bone plates to the first metatarsal and medial cuneiform of a patient undergoing a procedure. In some configurations, one of the bone plates is a helical bone plate while the other bone plate may or may not be a helical bone plate.

A method for pre-operative orthopedic planning includes obtaining only a high-resolution knee-joint scan of a patient, determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient, and determining a mechanical axis of the knee joint based on the anthropometric data. The method also includes preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis, and preparing a pre-operative surgical plan based on the image of the knee joint.
摘要:
An implant and guide are described, together with methods for configuring the same. The implant and guide are for maxillofacial osteosynthesis and may be provided as a kit. Three-dimensional models of the pre- and post-operative anatomy are used to define attachment points. These attachment points are used to define a structure for the implant and the guide.

A bone positioning device can include a fixation pin for attachment to a first bone and a fixation pin for attachment to a second bone. A first block having an aperture can be included for slidably receiving a fixation pin, and a second block having an aperture can be included for slidably receiving a fixation pin. A multi-axis joint can connect the first block and the second block, where the multi-axis joint allows the first second blocks to move with respect to each other about more than one axis.
