Disclosed is a medical device having a substrate having an exposed surface and a texture over at least part of the exposed surface. The texture includes a plurality of nanofeatures that inhibit bacterial adhesion on the surface and that also inhibit bacterial growth on the surface and have a size range between about 0.01 nanometers and about 1,000 nanometers. The texture can include a plurality of nanofeatures applied thereto such that the texture has a first particle size at a first location, a second particle size at a second location, and a gradient of particle size from the first particle size to the second particle size between the first location and the second location.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

A distance interbody device for introducing a biomaterial to a vertebral body includes a shaped body and a dispense mechanism operable to dispense biomaterial. The shaped body includes a top side, a bottom side, and a lateral wall forming a peripheral wall that extends between the top and bottom sides. The shaped body is provided with at least one through channel and at least one anchoring element. The through channel includes an internal reservoir for the biomaterial. The through channel passes through the anchoring element to at least one outlet opening located in the at least one anchoring element.

In described embodiments, an implant has an outer perimeter. The implant includes a top surface extending generally in a first plane and a bottom surface extending in a second plane. The second plane extends obliquely with respect to the first plane. The first plane intersects the second plane outside the outer perimeter of the implant. A medial surface extends between the top surface and the bottom surface proximate to the intersection of the first plane and the second plane. A lateral surface extends between the top surface and the bottom surface distal from the intersection of the first plane and the second plane. An anterior surface extends a first distance between the top surface and the bottom surface between the medial surface and the lateral surface. A posterior surface extends a second distance between the top surface and the bottom surface between the medial surface and the lateral surface. The second distance is greater than the first distance.

The invention relates to an assembled vertebral body used in a cervical reconstruction operation, comprising: an upper connecting element, an artificial vertebral body element and a lower connecting element, wherein the upper connecting element is disposed at an upper part of the artificial vertebral body element, the lower connecting element is disposed at an lower part of the artificial vertebral body element, and wherein the artificial vertebral body element is assembled with the upper connecting element and the lower connecting element, respectively. The invention has the advantages that the artificial vertebral body element is customized in accordance with the characteristics of patients and printed in 3D, and the length of the artificial vertebral body element can be precisely adjusted to adapt to the patient. Since the lower connecting element is standard part, the upper connecting element is standard part or non-standard part, and the artificial vertebral body element is non-standard part, in comparison to the traditional 3D printing which needs to be printed integrally, the adjustable assembled artificial vertebral body can reduce 3D printing materials and reduce the cost of 3D printing, thus reducing medical costs for the patient. The shape of the nested parts of the elements is a non-circular shape, which can resist rotation, so that no relative movement occurs among the three elements of the artificial vertebral body.

Disclosed is a medical device having a first implant portion having a proximal end, a second implant portion connected to the first implant portion, the second implant portion having a distal end, and a driver assembly removably connected to the distal end, the driver assembly comprising a drill connected to the distal end at a connection.

A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention device whose function is to prevent migration of the load bearing device. One or more fasteners secure the retention device to the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion. The second piece can be configured to include lips that abut the apothyseal rings during, with the plate including bores angled such that fasteners penetrate the apothyseal rings.

Disclosed are prosthesis systems and methods that provide porous fixation rings by which the articulating surfaces of the implant can be exchanged such that the anatomic surfaces can be converted to reverse surfaces, while not exchanging the fixation components. Also disclosed herein are methods by which the surgeon can implant an inset anatomic articulating glenoid implant whereby at a later date, can remove the anatomic articulating surface and replace it with a reverse articulating surface such that the primary means of fixation remains well fixed in the glenoid fossa at the moment of articular exchange.
