BIODEGRADABLE ANTIBACTERIAL BIOACTIVE CERCLAGE TAPE FOR COVERING FIXATION OF BONE FRAGMENTS AND SPLINTERS IN FRACTURES AND DEFECTS OF LONG BONES Russian patent published in 2024 - IPC A61B17/82 A61L27/12 A61L27/14 A61L27/46 A61L27/58 

FIELD: medicine.

SUBSTANCE: biodegradable bioactive cerclage tape for covering fixation of bone fragments and splinters in case of fractures and defects of long bones, comprising a connecting element, which includes a row of teeth located on one end of the tape, and a lock with a through hole for receiving a tape with a locking element, which blocks the tape inserted into the through hole from moving in the reverse direction. Tape is made from a composite formed from a biodegradable polymer, which includes a bioactive component. Tape is made of polycaprolactone PCL with length of 150 mm, 2 mm thick, 5 mm wide, or the tape is made of poly-L-lactic acid PLLA with length of 350 mm, thickness of 2 mm, width of 4 mm, or the tape is made of polyglycolic acid PGA, with length of 200 mm, thickness of 3 mm, width of 6 mm, or tape is made of polylactic-glycolic acid PLGA with length of 180 mm, thickness of 1 mm, width of 4 mm, or tape is made of poly-DL-lactic acid PDLLA, length of 280 mm, thickness of 1.5 mm, width of 6 mm.

EFFECT: invention provides low-traumatic fixation of bone fragments in fractures, combined with the possibility of having a favourable effect on osteogenesis, suppressing infectious processes and self-elimination after implantation.
