The Food & Drug Administration cleared Etex Corp.‘s orthopedic putty for use in small-bone repairs.
The Cambridge biotech said the federal watchdog agency gave the nod to 1cc and 5cc sizes of its Beta-bsm injectable paste and Gamma-bsm moldable putty, on top of existing clearances for the 5cc and 10cc sizes.
The bone substitute materials are used to make osteo-conductive scaffolds that ape the nanocrystalline structure of human bone. The smaller sizes were developed for hand and foot/ankle surgeries. The products are used to fill voids in bone that the bone doesn’t depend on for stability.
