Abstract: Described herein are systems and methods in which a surgeon can use computer-implemented deformity assessment and correction tools to create 3D models of a bone. To ensure adequate healing, a surgeon may choose to use a prefabricated bone plate, a semi-customized bone plate, or a fully-customized bone plate to hold first and second bone portions in a corrected position. To select the appropriate prefabricated bone plate, the surgeon may identify three landmark locations on the first and second bone portions corresponding to desired fixation hole locations on the bone plate. The surgeon can then use a software application to evaluate multiple bone plate designs in a library and compare the average proximity of the landmark locations to fixation hole locations on each of the bone plate designs. Then, the surgeon can determine which bone plate design best fits the patient anatomy based on his comparison.

Abstract: Implant delivery systems are configured to deploy multiple implants into targeted tissue within a patient without disengaging a delivery component of the systems from its insertion site in the patient. Various combinations of spooling assemblies, spring-loaded features, manifolds, indexing mechanisms, gearings, and manually engageable actuators operate to deploy the implants in a controlled, serial fashion. Implants or portions thereof are pre-loaded into the handle assemblies of the delivery systems or contained in removable cartridges configured for coupling to the handle assemblies.

A modular attachment member may be adapted to be couple to the first joint and include a worm gear adapted to engage gear teeth of the actuation mechanism. The modular attachment member may include a radiofrequency identity tag mechanism adapted to be read by a tag reader of a tool, the tool adapted to couple to the attachment member to rotate the worm gear to increase or decrease the effective length of the strut.

Abstract: A tissue repair apparatus includes a housing, a rotatable shaft at least partially disposed within the housing, and first and second curved needles coupled to the shaft. The housing defines a gap between a first edge of the housing and a second edge of the housing, the gap adapted to receive tissue. The first and second needles curved needles being articulable within the housing from a delivery position, at which the first and second needles are spaced from the gap, to a deployed position, at which the first and second needles extend through the gap. Actuation of the shaft simultaneously articulates the first and second needles and the first needle enters the gap before the second needle enters the gap.

Abstract: Disclosed herein are apparatuses and methods for intraoperative on-demand implant customization in a surgical setting. An apparatus may include a storage portion, an implant customization portion and an interface. The storage portion may house implant blanks and implant accessories.
