Methods During Sept.,2005,to Dec. 2012,17 patients after operation of internal fixation operation in The Second Dept. of Orthopaedics,Jiangxi Provincial People’s Hospital were recruited. The home-made 5 mm narrow bone spade,various kinds of metal conduits,3. 1 mm mini-type trepan and pot-like power-driven grinder were all employed for the operation. Under condition of epidural block type of brachial plexus block type local anesthesia and combined with peripheral nerve block anesthesia,0. 5-1 cm incision was made and minimally invasive bone grafting operation was conducted. Results Of the 17 cases,9 cases showed ground glass changes at the broken ends after X-ray test after one month and showed signs of fracture healing after three months; 6 cases showed signs of fracture healing after 6 months; one case exhibited fixed fracture in three months and was conducted re-operation,which showed no healing signs after one year and was treated with vascular pedicle bone graft and healed up at last.
