A method of manufacturing a surgical implant includes simultaneously forming a first component and a second component of the surgical implant. Formation of the first and second components includes depositing a first quantity of material to a building platform and fusing the first quantity of material to form a first layer of the first and second components. The method of manufacturing also includes depositing a second quantity of material over the first layer of the first and second components and fusing the second quantity of material to form a second layer of the first and second components. The surgical implant is fully assembled upon the completion of the formation of the first and second components.

The present invention discloses a prosthetic device for reconstruction of sternum, ribs, and clavicles, comprising a manubrium plate attached to a sternum plate by means of a joining plate. The manubrium plate has spherical ends coupled to the clavicle plate by screwing into a cup lock. The manubrium plate has extensions with holes, on which rib plates are seated. Similarly, the sternum plate has extensions with holes, on which rib plates are seated.

A monolithic rib plate is described. The rib plate comprises multiple first screw orifices located substantially along a first line and connected by first bridges, multiple second screw orifices located laterally on one side of the first line and connected by second bridges, wherein one or more of the second bridges have a smaller cross-section than the first bridges, and third bridges, each connecting one of the second screw orifices with one of the first screw orifices. Also described is a rib plate system comprising the monolithic rib plate and at least one of one or more polyaxial locking screws, a tool for removing the second bridges, a tool for bending the monolithic rib plate, and one or more orifice bridge plates.

According to an aspect, a spacing element for spacing a fixation plate away from a bone to which the fixation plate is secured is provided. The spacing element has a body with a bone interface side and a plate interface side and sidewalls extending thereinbetween, said bone interface side having a bone contacting surface having contours conforming to surface contours of the bone. A corresponding fixation plate, fixation plate kit, and method for designing a patient-specific spacing element are also provided.

Disclosed is a bone cutting and shortening system and the method of using the same, the system comprising a bone plate and a cutting guide adapted to slidingly engage by inserting the cutting guide into the bone plate from the overhead direction, the cutting guide adapted to facilitate parallel cutting planes on a bone at precisely ascertainable offset distances, and the bone plate adapted to stabilize the shortened bone after cutting.

A plate system includes a retention cap and a plate. The retention cap includes a head with tangs and a shank. The shank includes protrusions at an end of the shank and relief cut-outs clocked relative to the protrusions. The plate includes screw holes and a locking feature. The locking feature includes an assembly guide adapted to guide the shank and features thereof into the locking feature, locking detents distal to the top surface of the plate and adapted to receive the protrusions and interfere with rotational movement of the retention cap, and a retainer positioned axially between the assembly guide and the locking detents. The retainer is adapted to prevent axial movement of the retention cap. The locking feature is adapted to hold the retention cap with the tangs overlapping the screw holes and with the tangs not overlapping the screw holes.

The present invention provides a method for generating a bone fixation implant and related preoperative planning. The method comprises a first step of determining at least the orientation and the position of the fixation means, based on a 3D model of the bone fragments. The method may include a second step of defining the shape of one or more bone plates, based on the output of the first step. The method may further include a third step determining tools for applying fixation means during surgery, according the optimized configuration defined in the first step and applying the bone plates from the second step. The method may even further include a fourth step, quantifying construct stability for a given patient following surgery, thereby allowing early weightbearing.
