An implant for use in orthognathic surgery of a mandible may include a longitudinal plate member and a plurality of pre-configured guides coupled to the plate member. The longitudinal plate member is pre-bent to correspond to the post-operative shape of the mandible; and the guides are pre-configured to align the plate member with the mandible when the implant is positioned against the mandible after the mandible has been separated.

Orthognathic implant and methods of use

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.

Surgical instrument mounted display system

A bone graft system includes a two-dimensional mesh sheet sized and shaped to, when folded along fold lines, form a three-dimensional graft containment structure configured to be packed with a bone graft material for placement within a target area of a bone, the mesh sheet including a first end flap connected to a remaining portion of the mesh sheet via a first fold line and a second end flap connected to the remaining portion of the mesh sheet via a second fold line, a third fold line extending from the first fold line to the second fold line so that the remaining portion is configured to be wrapped around folded first and second end flaps to form the graft containment structure, the first and second end flaps substantially corresponding to a profile of the target area of the bone.

Fold-up containment device for bone defects

A graft cage includes cross-sectional portions and longitudinal members. Each portion includes base transverse members forming a cage base; a first arm including first arm transverse members; a second arm including second arm transverse members; base connecting struts, each base connecting strut extending between first one and second one of the base members; first arm connecting struts, each first arm connecting strut extending between a first one of the first members and a second one of the first members; and second arm connecting struts, each second arm connecting strut extending between first one and second one of the second members. The longitudinal members connect the portions to one another. Intersections of the portions with the longitudinal members forming pores in the first and second arms. The pores receive an arm tip of a further graft cage therein to interlock the cage with the further cage.

Modular bone graft cage

A bone graft containment device includes a plurality of cage segments connected to one another along a longitudinal axis, each of the cage segments connected to an adjacent one of the cage segments via a connection which permits movement of the cage segments relative to one another so that the bone graft containment device is deformable to a desired configuration for placement within a target space of a bone, each cage segment extending along from a first end to a second end and including a channel extending therethrough so that channels of the plurality of cage segments, in an initial configuration, are aligned along the longitudinal axis, the channels configured to be packed with a bone graft material.

Bendable graft containment cage

A bone graft containment device includes a body formed via one or more helical structures extending about a longitudinal axis of the body from a first end to a second end to define a channel extending longitudinally therethrough. The channel is configured to receive a bone graft or bone graft substitute material therein, the one or more helical structures formed of a material permitting the body to be one of expanded, compressed and curved to fill a target space of a target bone.

Helical graft containment cage

A bone graft containment device includes a body extending longitudinally from a first end to a second end. The body is defined via a strut framework sized and shaped to correspond to an outer surface of a target bone. The strut framework defines an interior space configured to receive a bone graft or bone graft substitute material. The device also includes a first grasping structure and a second grasping structure extending from an exterior of the body. The first and second grasping structures are configured to receive a bone fixation plate therebetween.

Splitting attachment for graft containment cage

A bone graft containment device includes a body extending longitudinally from a first end to a second end. The body includes a channel extending longitudinally therethrough. The device also includes a fluid delivery structure received within the channel. The fluid delivery structure includes a central tubular member extending along a length of the channel and a laterally extending tubular member extending laterally from the central tubular member to a fluid receiving opening. The central tubular member includes a plurality of openings extending laterally through a wall thereof, so that, when the fluid receiving opening is connected to an external fluid source, fluid is passed through the laterally extending tubular member and the central tubular member to be dispersed to a graft material packed within the channel via the plurality of openings.

Externally fed graft containment cage/scaffold

A method of making a patient specific surgical orthopedic implant includes obtaining a virtual model of the orthopedic implant that is configured to fit over a particular tissue body, and virtually designing holes of the orthopedic implant.

Method for producing patient-specific plate

A method for treating a mandible including forming an initial digital 3D model of a mesh graft containment device based on dimensions of a target space of a mandible to be filled via the graft containment device, the 3D model of the graft containment device defined via a buccal surface, a lingual surface, a superior surface and an inferior surface, individually adjusting one of the buccal surface and the lingual surface relative to a first midplane, which extends through a longitudinal axis of the graft containment device between the buccal and lingual surfaces, to add or remove bulk along a desired portion of the 3D model of the graft containment device to form an adjusted 3D model, and forming a final graft containment device for placement in the target space of the mandible based on the adjusted 3D model.

Patient-specific mandible graft cage

The present invention generally relates to mandibular prostheses. More particularly, the invention relates to a condylar-head replacement for reconstruction of the temporomandibular joint after resection of the condyloid process. The present invention provides a condylar-head replacement comprising a condylar-head attachment that may be adjustably positioned on a reconstruction plate to achieve various condylar-head heights. The condylar-head height adjustment allows the condylar-head replacement to be fit to a particular patient. The condylar-head replacement of the present invention obviates the need for custom fabrication of a condylar-head replacement for a patient.
