INTRAOPERATIVE IMPLANT AUGMENTATION

Methods and systems of augmenting an implant intraoperatively and preparing a cone for revision surgical procedure are disclosed. A system includes a cutting device, a tracking and navigation system and a cutting system in operable communication with the cutting device and the tracking and navigation system. The cutting device includes a communication system, a cutting element, and a plurality of optical trackers. The tracking and navigation system is configured to detect a location of optical trackers. The control system is configured to cause the tracking and navigation system to detect the location of the cutting device, determine a revised shape for an implant cavity, cause the cutting device to cut the implant cavity to the revised shape, select a shape for a cone to be placed in the revised implant cavity, and machine the cone to the selected shape.

METHOD AND APPARATUS FOR RESTORING ARTICULAR CARTILAGE
20170296156 · 2017-10-19 ·

The present invention comprises the provision and use of new and improved arthroscopic instrumentation for (i) harvesting a tissue biopsy from a non-critical section of a joint, and (ii) sizing and seating an autologous graft at an implant site.

SHAPE SENSING FOR ORTHOPEDIC NAVIGATION

An optical shape sensing system includes an attachment device (130) coupled at an anatomical position relative to a bone. An optical shape sensing fiber (102) is coupled to the attachment device and configured to identify a position and orientation of the attachment device. An optical shape sensing module (115) is configured to receive feedback from the optical shape sensing fiber and register the position and orientation of the attachment device relative to an anatomical map.

09814804 · 2017-11-14 · ·

Methods of providing dose controlled application of bone graft materials are disclosed. In particular, methods for determining a target quantity of bone graft material for clinical application in order to ensure maximum clinical results are provided. These methods comprise determining the target weight of the material to be applied.

Patient-specific spinal fusion cage and methods of making same

A method of determining disc space geometry with the use of an expandable trial having endplate-mapping capabilities. An expandable trial is inserted into the disc space and its height is adjusted to obtain the desired decompression and spinal alignment (which is typically confirmed with the use of CT or Fluoroscopic imaging). The endplate dome/geometry dome is then determined by one of the following three methods: a) direct imaging through the trial, b) balloon moldings filled with flowable in-situ fluid (for example, silicon, polyurethane, or PMMA) from superior/inferior endplates or c) light-based imaging through superior & inferior balloons.

KNEE ARTHROPLASTY VALIDATION AND GAP BALANCING INSTRUMENTATION

To address technical problems facing knee arthroplasty resection validation, the present subject matter provides a tracked knee arthroplasty instrument for objective measurement of resection depth. By performing a precise comparison between the location of the tracked knee arthroplasty instrument and a reference location, the knee arthroplasty instrument measures and validates each tibial and femoral resection. To address technical problems facing validation of joint laxity following knee arthroplasty, the tracked knee arthroplasty instrument is shaped to validate the flexion gap and extension gap. When the tracked knee arthroplasty instrument is inserted between the resected tibial plateau and femoral head, the instrument shape validates whether the desired flexion gap and extension gap have been achieved.

Trochlear resurfacing system and method
11337819 · 2022-05-24 · ·

A system for repairing a defect on an articular surface of a patient's trochlear region, the system comprising a guide block comprising a body having an exterior surface configured to engage with the saddle portion and ridge portions of the patient's trochlear region, a protrusion extending generally from the body and configured to be received in a first bore formed in the articular surface along a reference axis, and a first cavity extending through the body configured to establish a first working axis displaced from the reference axis, wherein the exterior surface of the body and the protrusion are configured to secure the location of the guide block about the patient's trochlear region. A method for preparing an implant site in bone, comprising: establishing a reference axis extending from the bone; creating a bore in the bone by reaming about the reference axis; securing a guide block about the articular surface; establishing a first working axis extending from the bone using the guide block, the first working axis is displaced from the reference axis; and creating a first socket in the bone by reaming about the first working axis, wherein the first socket partially overlaps with the bore.

Graft Delivery Device with Accurate Dispensing

Disclosed herein are systems and methods for graft delivery with accurate dispensing. For example, a device for delivering graft material to a target site includes an actuation mechanism and a tube. The tube defines a lumen and an open end and is configured to receive graft material through the open end. The tube includes a pressure relief opening and a dosage window. The pressure relief opening is disposed in a wall of the tube, defining a pressure chamber between the open end and the pressure relief opening. The device further includes a plunger positioned within the lumen of the tube and coupled to the actuation mechanism such that at least a portion of the plunger (or the actuation mechanism) is visible through the dosage window. The actuation mechanism is configured to advance the plunger toward the open end to deliver graft material through the open end.
