A system for monitoring the ossification of an internally fixated fracture in a bone of a subject includes an implantable fixation device and an external wireless reader operative to transmit relative load data experienced by a bone plate across a fracture to a data server where trends in the change in added bone-support provided by the bone plate may be visualized. The implantable fixation device includes a primary load sensor and a reference load sensor, where a load value from the reference load sensor may be used to normalize the load value from the primary load sensor. The external wireless reader is in wireless communication with the implantable fixation device and is operative to receive a signal indicative of the load from each load sensor and to energize each load sensor via inductive charging.

Bone fixation monitoring system

A device for containing bone graft material includes an outer sleeve including a first proximal longitudinal split extending along a length thereof and a first distal longitudinal split extending along a length thereof and an inner sleeve connected to the outer sleeve via at least one strut so that a bone graft collecting space is defined therebetween, the inner sleeve including a second distal longitudinal split extending along a length thereof in combination with an interstitial mesh extending circumferentially between the inner and outer sleeves to hold graft material in the bone graft collecting space, the interstitial mesh including a third longitudinal split extending along a length thereof so that a distal side of the device may be spread open to open the distal longitudinal slot from the outer sleeve, through the interstitial mesh and the inner sleeve to a space radially within the inner sleeve.

In one example a method of fracture reduction includes imaging, intraoperatively, a fractured bone of a patient to obtain a first representation of the fractured bone in a computing system. The fractured bone defines at least a first bone fragment, and a second bone fragment that is separated from the first bone fragment by a fracture. The method includes imaging, intraoperatively, a contralateral bone of the patient to obtain a second representation of the contralateral bone in the computing system. The method includes generating, intraoperatively in the computing system, a mirrored representation of the first representation or the second representation. The first representation is compared to a representation of a desired orientation of the fractured bone, where the representation of the desired orientation is the mirrored representation of the second representation. Alternatively, the mirrored representation is compared to the representation of the desired orientation of the fractured bone, where the representation of the desired orientation is the second representation.

Image matching for fracture reduction

A C-arm, or a mobile intensifier device, is one example of a medical imaging device that is based on X-ray technology. Because a C-arm device can display high-resolution X-ray images in real time, a physician can monitor progress at any time during an operation, and thus can take appropriate actions based on the displayed images. Monitoring the images, however, is often challenging during certain procedures, for instance during procedures in which attention must be paid to the patient's anatomy as well as a medical imaging device display. In an example, a surgical instrument assembly includes a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The display can be configured to display visual information comprising X-ray images generated by a medical imaging device.

Surgical instrument mounted display system

A device for treating bone in a living body includes (a) comprises an implant configured for attachment to a bone; (b) a first sensor measuring a strain on a first portion of the implant, the first portion of the implant being configured to be mechanically coupled to a weakened portion of a bone when the implant is coupled to the bone in a target position in combination; and (c) a second sensor measuring strain in a non-weakened portion of the bone.

Method of normalizing implant strain readings to assess bone healing

A bone plate system is designed for use on a bone, which may be a humerus. The system includes an elongated bone plate extending along a longitudinal axis, the bone plate having an upper surface, an opposed bone-facing surface, and a boundary edge of the bone plate; and at least one threaded fastener hole extending from the upper surface to the bone-facing surface. The fastener holes are designed to receive a bone fastener to couple the bone plate to the bone. A plurality of first suture-receiving structures are connected with the bone plate and project from the boundary edge of the bone plate, so that the first suture-receiving structures are spaced from each another along the boundary edge of the bone plate. Each of the first suture-receiving structures comprises a wire loop anchored to the upper surface or to the bone-facing surface of the bone plate.

Bone plate with structures for attachment of sutures

A surgical instrument assembly may include a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The processor can be configured to determine a position of the medical imaging device, from which the medical imaging device can generate an X-ray image that includes holes of an intramedullary nail shown as circles, for instance perfect circles. In an example, the processor identifies the intramedullary nail, so as to determine an intramedullary nail identity, and determines the position of the medical imaging device based on a portion of at least two locking holes of the intramedullary nail and based on the intramedullary nail identity.

A method of evaluating a bone fracture reduction includes imaging, intraoperatively, a fractured bone to obtain a representation of the fractured bone in a computing system. The fractured bone defines at least first and second bone fragments separated by a fracture. The method includes imaging a contralateral bone of the patient to obtain a representation of the contralateral bone in the computing system and further includes generating, intraoperatively in the computing system, a virtual model of the fractured bone from data presented in the representation of the fractured bone and a virtual model of the contralateral bone from data presented in the representation of the contralateral bone. The method includes comparing, intraoperatively in the computing system, a spatial dimension measured with respect to the virtual model of the fractured bone with a corresponding spatial dimension measured with respect to the virtual model of the contralateral bone.

Intraoperative imaging and virtual modeling methods, systems, and instrumentalities for fracture reduction

A device and method for treating a hone includes a bone plate including first and second portions joined to one another via a connecting portion, a rigidity of the connecting portion being less than rigidities of each of the first and second portions in combination with a first sensor mounted on the first portion measuring strain on the first portion and a second sensor mounted on the second portion measuring strain on the second portion.

Device and method for normalizing implant strain readings to assess bone healing

A method for syndesmosis fixation including at least one suture anchor configured to be implanted into bone and at least one suture assembly configured to extend from the suture anchor and about at least a portion of a fibula when the suture anchor is implanted in a tibia on either side of a fibular notch of the tibia. The suture assembly is selectively adjustable from a non-tensioned condition to a tensioned condition to stabilize and reduce the fibula relative to the tibia.

Apparatus and method for syndesmosis fixation

A bone fixation system is configured to be implanted and secured to a bone so as to stabilize a bone. The bone fixation system includes an implant having a plate portion configured to be secured to a first segment of the bone by a first bone anchor, and a second segment of the bone by a second one anchor. The implant further includes a mesh portion configured to abut a third segment of the bone to prevent movement of the third segment relative to both the first segment and the second segment. The implant defining an outer perimeter defined in part by the plate portion and in part by the mesh portion.
