Abstract: The present disclosure discloses a bone stabilization device (also referred to as a bone tape), which includes a composite flexible construct including a rigidifiable biocompatible sheet structure having first and second opposed surfaces. A biocompatible cement is located on the first surface. In use the composite flexible construct is applied to a bone with the cement contacted directly to the bone. The cement is made of a material that, once adhered to the bone, is curable to mechanically and/or ionically bond to the sheet structure and to chemically bond to the bone to achieve a permanent bond. The bone tape allows simultaneous alignment and stabilization of multiple articulated fragments for successful 3D reconstruction of shattered bones. Initial flexibility and translucency provided by the bone tape can facilitate the temporary stabilization and alignment adjustment of multiple fragments, prior to permanent rigid bonding.

Abstract: Disclosed herein are patient-specific craniofacial implants structured for filling bone voids in the cranium as well as for simultaneously providing soft tissue reconstruction and/or augmentation for improved aesthetic symmetry and appearance. Pterional voids or defects generally result from a chromic skull deformity along with a compromised temporalis muscle or soft tissue distortion from previous surgery. When muscle atrophy occurs in the pterion, temporal hollowing generally results where there would be soft tissue but for the atrophy. The patient-specific temporal implants herein are configured to have an augmented region adjacent the temporal region of the cranium in order to account for and correct any such temporal hollowing.

Abstract: A porous metal augment is sized for use in mandibular or maxillar bone. The porous metal material of the augment facilitates and promotes ingrowth of the surrounding bone into the porous metal structure, thereby rebuilding a suitable foundation for affixation of dental implants. A non-porous core or insert can be embedded within the porous metal body of the augment, and can be made of a material suitable for firm threaded fixation of dental implants thereto. For example, the metal core can be formed of a titanium structure that has sufficient strength and resiliency to form a firm and long lasting threaded connection with a threaded stem of a dental implant.

Abstract: Embodiments relate to systems and methods for a cranial implant assembly adapted for insertion during a craniectomy procedure. In aspects, the inventive cranial implant assembly can contain a peripheral attachment member for attachment to the edge of a skull opening, as well as an articulated spanning member that over-arches and holds a cover in place over the opening. The articulated spanning member contains a central implant fastened or connected to a swollen dura in the skull opening. As swelling of the dura subsides, tension is exerted on guidewires in both the spanning member and cover to draw those constructs into a rigid state. The tips of the spanning member can gradually approach the peripheral attachment member, and register into place using a locking mechanism, such as a pair of opposing magnets. As a result, only one surgical operation or procedure Is required to both perform a craniectomy and implant a supporting assembly for eventual skull regeneration.

Abstract: A coating for an orbital implant has an anterior portion having a different bioabsorbability than a posterior portion. This allows the implant to have an insertion surface, to reduce irritation, to prevent implant exposure, and to anchor muscles. The coating has a visual indicator to facilitate orientation. Shell materials are further selected to allow for sterile packaging, to secure therapeutic agents thereon, and to secure the coating to the core. Passageways enhance fluid flow to and from the core, and expose the core surface to muscles. The passageways are sized and shaped to reduce irritation. In an alternate embodiment, the anterior coating portion has a vaulted zone creating a gap between the undersurface of the coating and the outer surface of the core through which a suture can easily pass. Perforations through the coating provide targets for passage of the suture through the coating.
