Rotational actuation expands the spacer in situ while simplified structural interfaces preserve room for bone cement or graft material.
Patient-specific contours and resection planes help measure articular bone loss and position a graft for joint restoration.
Protrusions resist implant migration while a deployable, biocompatible covering helps seal intervertebral disc defects during spinal motion.
An elastic surgical staple shifts between relaxed and opened states to distribute fixation force, improve bone compression, and support healing stability.
Bone ingrowth is limited in traditional spacers; this foam-connected 3D lattice lets bone enter the implant to support spinal fusion.
Segmented links collapse for insertion, then expand in the intervertebral space while instruments control sizing, placement, and graft delivery.
A rotating and translating lid helps a modular spinal implant accommodate soft-tissue tension while maintaining vertebral spacing and retention.
Dual engagement features let one humeral stem accept anatomic or reverse inserts without stem removal, limiting bone loss during conversion.
Hinged endplates expand after insertion while a locking screw secures adjustable lordosis for spinal alignment and fusion.
Annealed, plasma-treated PVDF nanofibers generate intrinsic electrical cues and adjust calcium transport to promote BMSC osteogenesis.
A rotation lock stabilizes the draw bar during multi-axis cage expansion, reducing misalignment risk in spinal fusion procedures.
