Operative technique features in application of bioabsorbable implants for limb fractures treatment

Bioabsorbable screws and rods were used for treatment of different types and locations limb fractures in the CCH of RAS orthopedic trauma department between 2014 and 2016 for 120 patients. Interfragmentary fixation with bioabsorbable implants was applied as a single fixation method for 53 patients (44%), and in 67 (56%) cases it was combined with metallic plates and screws. Bioabsorbable implants were recognized as effective devices for interfragmentary fixation. Generally, bioabsorbable screws and rods did not require particulary scills for the surgeons brigade and accorded with AO principles of fracture management. However there were find out some features of that implant type application like implant destruction possibility when incorrect instrumentation was used, X-ray and visual transparency while implanted, that lead to some difficulties in length measurement and implant position assessment, a possibility of implant length adaptation, drilling through implanted device that eliminates risks of implants conflict, and gives an opportunity for augmentation of bone defects by screws. Also it is desirable to fix implants in two cortexes, and to use fully threaded and lag-screws together in a pair.
