The parameterized model may be generated based on a three-dimensional model that was generated based on multiple images of the patient's bone. The model production device adds parametric fixed geometry to the patient-specific surgical instrument model based on the parameterized model and subtracts the three-dimensional model of the patient's bone from the patient-specific surgical instrument model. Each contacting body may be positioned at a high-confidence part of the parametric model, and the parametric fixed geometry may be positioned at a low-confidence part. A patient-specific surgical instrument may be manufactured based on the patient-specific surgical instrument model.

Methods and devices for achieving semi-rigid bone fixation
An example method is provided for maintaining stability to an injury defined by a separation of two bones (e.g., the tibia and fibula), the separation being an injured distance greater than a pre-injury distance between the two bones in a first human patient. The method may include delivering a first apparatus for approximation of the two bones in the first human patient comprising the injury, the first apparatus including a flexible segment disposed between a first anchor and a second anchor. The method may further include maintaining, by the first apparatus, a restored distance between the two bones in the first human patient after a repetitive dynamic loading, the restored distance approximately equal to the pre-injury distance.

TECHNOLOGIES FOR MONITORING BONE INGROWTH OF AN ORTHOPAEDIC PROSTHESIS
A system for monitoring bone ingrowth includes an orthopaedic prosthesis having a circuit configured to transmit force sensor data indicative of an amount of force applied to a stem of the orthopaedic prosthesis in response to receiving power from an external power supply. The force sensor data is indicative of bone ingrowth of the orthopaedic prosthesis. As such, an orthopaedic surgeon may monitored the force sensor data over time to ensure bone ingrowth of the orthopaedic prosthesis has sufficiently occurred.
A medical screw, including: a first region comprising a constant diameter first root having a first diameter and a constant pitch multi-start thread; a second region forming a transition region; and a third region including a constant diameter root having the first diameter and a constant pitch thread, wherein the transition region is in between the first region and the second region and joins the first region with the second region, and wherein a lead of the constant pitch multi-start thread is different from a lead of the constant pitch thread.
An endovascular implant detachment mechanism is disclosed that can include an endovascular implant, a connector, a push wire, and one or more lock wires. The connector can be attached to a pinched end of the implant and can include an aperture at a second end. The connector can include a generally circular cavity distal to the aperture. The push wire can have a distal end including one or more slotted openings and configured to fit into the aperture in a first orientation. The one or more lock wires can be configured to fit into the aperture while the distal end of the push wire is in a second orientation. Axial rotation of the push wire can cause the distal end of the push wire to move from the first orientation into the second orientation and secure the push wire to the implant.

INSTRUMENTS AND METHODS FOR TENSIONING A SPINAL TETHER
Various methods and devices are provided for tensioning a tether. In one embodiment, a tether tensioning device is provided and includes an elongate shaft adapted to be positioned adjacent to a bone anchor implanted in bone, and a tensioning mechanism pivotally associated with the elongate shaft and adapted to couple to a tether seated across the bone anchor and to pivot relative to the elongate shaft to apply a tensioning force to the tether.

In some embodiments, a connector can be configured to couple a first fixation element (e.g., a first rod) to a second fixation element (e.g., a second rod). One or both of the first and second fixation elements can be included with the connector, or one or both can be separately provided. In some instances, at least one of the fixation elements is previously implanted in a patient. The connector can provide one or more degrees of freedom between the first and second fixation elements. The connector can also include a locking element configured to (1) lock one or more of the fixation elements to the connector, and (2) lock one or more of the degrees of freedom between the fixation elements. The connector can be configured to snap onto or otherwise engage a fixation element in a manner that provides tactile and/or audible feedback to the surgeon.

CUSTOMIZED PATIENT-SPECIFIC 3D PRINTED POSITIONING AUGMENT FOR ORTHOPAEDIC SURGICAL IMPLANT
An orthopaedic prosthetic component includes a manufactured acetabular shell component having an outer wall and an additively manufactured augment coupled to the outer wall. The augment includes an outer surface that defines a customized patient-specific negative contour shaped to conform to a positive contour of a patient's bone. A method for manufacturing the prosthetic component is also disclosed.
A rib fixation system, including: a rib plate having a plurality of screw holes; a first ring component with a screw hole and ridge; a second ring component with a screw hole and a slot configured to receive a portion of the first ring component; and a screw configured to be placed through one of the plurality of screw holes of the rib plate, the screw hole of the first ring, and the screw hole of the second ring, wherein the ridge of the first ring provides a stop for the second ring.
The objectives for the designs presented herein can be for a variably flexible and kink-resistant catheter for vascular applications. The designs benefit from good compressive and tensile stiffness. A braided wire support structure can be disposed around an inner liner and an outer layer having a plurality of outer jackets of variable durometer. A metallic reinforcing layer can be cut from a hypotube and be used as the primary structure for catheter stiffness, reducing the reliance on and number of jackets to transition stiffness changes along the length of the catheter. The metallic reinforcing layer can have one or more ribbon cut segments and one or more axial hole patterns laser cut into the hypotube to progressively evolve the stiffness from proximally regions with more column stiffness and distal regions with greater lateral flexibility. The polymer jackets can be reflowed to bond the structure together.
Surgical instrument calibration methods, systems, and devices are provided that allow a virtual representation of a surgical instrument to be modified to adjust for any variations in a distal tip of a surgical instrument. For example, an instrument calibration system is provided that can have a surgical instrument, a calibration instrument, and a monitoring system. The surgical instrument can have a distal tip and an orientation element thereon, and the calibration instrument can have a pivot point thereon and a calibration reference element attached thereto. The monitoring system can be configured to record movement of the surgical instrument with respect to the calibration instrument when the tip of the surgical instrument is inserted into the pivot point of the calibration instrument, and to calculate a deviation of the tip of the surgical instrument from a predefined ideal tip based on the recorded movement.

The present invention is directed an anchor assembly for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The anchor assembly preferably includes a bone anchor, a body with a rod-receiving channel, an insert member (preferably a bushing), and a locking cap with a saddle. The anchor assembly preferably enables in-situ assembly where the bone anchor may be secured to the patient's vertebra prior to being received within the body of the bone anchor assembly. Accordingly, the anchor assembly enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body may be snapped onto the bone anchor and a spinal rod may be inserted into the rod-receiving channel.
