IMPLANT FOR TOTAL EXTENDED LONG BONE DEFECT RESTORATION Russian patent published in 2015 - IPC A61F2/28 A61F2/30 A61F2/44 A61L27/14 A61L27/34 A61L27/36 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. What is described is a cage for total extended long bone defect restoration representing a hollow cylinder made of a carbon-carbon composite walls of which are perforated with multiple through holes providing surrounding tissue adhesion and blood vessel penetration inside the cylinder. An inner lumen of the cage is filled with a xenogenic osteoplastic material with an axial through hole used to facilitate a fixation procedure.

EFFECT: cage makes it possible to deliver the osteoplastic material to the defect region, prevents its migration and enables improving the results of the long bone defect correction outcome by the reliable fixation of the osteoplastic material within the defect region due to optimum strength characteristics of an outer support frame, the effective regeneration within the defect region by the osteoplastic material, the absence of adverse effects of the long-term implantation, and as a result no necessity to remove the cage, and ensured possibility of the intraoperative adjustment of the cage size depending on the defect size.
