An expandable augment system is provided for use with an acetabular cup. The expandable augment system can include an expandable augment module that is adjustable in size and that can be adjusted incrementally between a fully collapsed state and an expanded state. A first portion of the expandable augment module is attachable to an outer surface of an acetabular cup and a second portion of the expandable augment module is attachable to bone or to a fixed augment module (e.g., a fixed angle augment module) that is attached to bone and interposed between the adjustable augment module and bone.

An implant includes a plate having a plurality of fastener holes, the plurality of fastener holes being configured to receive a plurality of fasteners, respectively; a spacer coupled to the plate and configured to be inserted into a treatment region; and a fastener lock movably coupled to the plate and configured to lock the plurality of fasteners.

In the present disclosure, an artificial joint stem includes a base and a coating film located on the base. The base includes a first region, a second region, and a third region located in sequence. The coating film contains a calcium phosphate-based material and an antimicrobial material. The coating film is located across the first region and the second region, and the third region is exposed from the coating film. The surface of the coating film located in the first region has a larger surface roughness than the surface of the base in the third region.

The present disclosure relates to the field of medical instruments, in particular to a pad for acetabular bone revision and reconstruction and a fixing structure for a pad and an acetabular cup prosthesis. The pad is located between an acetabular cup prosthesis and the acetabular bone, and is connected to the acetabular cup prosthesis and the acetabular bone respectively. The pad includes a first component and a second component which has the same or different radius and shape as or from the radius and shape of the first component; the first component is movably connected with the second component; and the shape of the connected first component and second component is matched with a defective part of the acetabular bone.

Methods, compositions, and systems are provided for characterization of modified nucleic acids. In certain preferred embodiments, single molecule sequencing methods are provided for identification of modified nucleotides within nucleic acid sequences. Modifications detectable by the methods provided herein include chemically modified bases, enzymatically modified bases, abasic sites, non-natural bases, secondary structures, and agents bound to a template nucleic acid.

A method of preparing an interpositional implant suitable for a knee. The method includes determining a three-dimensional shape of a tibial surface of the knee. An implant is produced having a superior surface and an inferior surface, with the superior surface adapted to be positioned against a femoral condyle of the knee, and the inferior surface adapted to be positioned upon the tibial surface of the knee. The inferior surface conforms to the three-dimensional shape of the tibial surface. The implant may be inserted into the knee without making surgical cuts on the tibial surface. The tibial surface may include cartilage, or cartilage and bone.

In the present disclosure, an artificial joint stem includes a base having an outer surface including a rough surface, and a coating film disposed on the rough surface of the base and containing a calcium phosphate-based material and an antimicrobial agent. The rough surface includes an exposed region exposed from the coating film.

A method of resurfacing a facet joint with a facet implant system. The facet joint includes a superior facet and an inferior facet that are adjacent to each other and movable with respect to each other. A first facet implant component is provided that has a first visualization marker. The first visualization marker includes a first marker section and a second marker section. The first marker section is oriented at an angle with respect to the second marker section. The first facet implant component between the superior facet and the inferior facet. A location and an orientation of the first facet implant component are determined using an imaging technique that locates the first visualization marker.

The present disclosure relates to the field of medical instruments, in particular to a pad for acetabular bone revision and reconstruction and a fixing structure for a pad and an acetabular cup prosthesis. The pad is located between an acetabular cup prosthesis and the acetabular bone, and is connected to the acetabular cup prosthesis and the acetabular bone respectively. The pad includes a first component and a second component which has the same or different radius and shape as or from the radius and shape of the first component; the first component is movably connected with the second component; and the shape of the connected first component and second component is matched with a defective part of the acetabular bone.

The present invention relates to a spinal fusion cage which is inserted between vertebral bodies in a state where the cage has the lowest height and is height-adjustable in the inserted state, thus making it possible to replace cages having heights in a certain range by a single cage. Therefore, manufacturers can reduce product groups that need to be produced and can also reduce product stock. Further, in contrast to the conventional cages having predetermined heights at regular intervals, the height of the inventive cage can be linearly adjusted according to the distance between the vertebral bodies of a patient, and thus a surgery for the patient can be performed using the cage adjusted to an optimum height according to the patient's condition.
