Abstract:
BACKGROUND:Currently, surgical treatment for Sanders III type, IV type fractures to restore damaged subtalar surface of the calcaneus and calcaneal shape, in order to reduce the incidence of traumatic arthritis has reached a consensus, and whether bone grafting is selected during surgery for calcaneal fractures has been a controversial issue. OBJECTIVE:To observe the clinical effect of Genex synthetic bone transplants and locking plate on comminuted calcaneal fractures. METHODS:Twenty-one cases of Sanders III type, IV type calcaneal fractures were retrospectively analyzed, including 16 males and 5 females, aged 22 to 55 years. After fracture reduction, a dough-like Genex bone graft was implanted into the defect region via lateral“L”shaped approach, and then the lateral wal of the bone was reset fol owed by internal fixation with the pre-curved locking plate. Fol ow-up observation was performed for fracture healing, Bolher angle and the Maryland Foot Score. RESULTS AND CONCLUSION:Total y 21 patients were fol owed up for 8-16 months. The fractures were healed without displacement, col apse and rejection. The bone graft was degraded within 6 months and completed absorbed after 1 year. According to Maryland Foot Score, the excellent rate was up to 86%, and the Bolher angle was increased from an average preoperative (5.3±3.35)° to postoperative (24.3±1.06)°. Genex artificial bone meal is a biomaterial that can be completely absorbed, has good plasticity and strong supporting force, and it is able to ful y fil bone defects, be easy to fracture reduction, induce bone formation, and promote fracture healing.
