Title:
EXTERNAL SYSTEM FOR STABILISATION AND DISTRACTION OF CURVED BONY SURFACES
Document Type and Number:
WIPO Patent Application WO/2011/121512
Kind Code:
A3
Abstract:
This invention creates an external system for stabilization, distraction and compression osteogenesis for curved bone surfaces of the body in craniofacial skeleton, thoracic cage, pelvis and other similar bony surfaces. The system allows anatomical stabilization along with simultaneous predictable and controlled distraction osteogenesis for bone losses in these regions where curvilinear regenerate is required to match the functional, occlusal and aesthetic requirements of reconstruction. The system is comprised of a semicircular, threaded rod (la) conforming to the shape of the curved bony surfaces. This rod has an assembly of various types of pin holding clamps (2a) meant for functions of stabilization of the mandible, multivector distraction, transport distraction and compression osteogenesis. All these assemblies engage on the threads of the central rod and move in a controlled directional manner. Each assembly is composed of two rectangular blocks which are connected to each other by a controlled ball and socket type of attachment.
