Radiographic image of one patient who received vetebralplasty and short instrumentation. a. Lateral roentgenogram of a 35-year-old male patient showing a L3 burst fracture; the kyphotic angle is 20°. b. Postoperative lateral roentgenogram showing good reduction (the kyphotic angle is 0 degree) through vertebroplasty and short instrumentation with intradiscal and paraspinal leakages 3 days after surgery. c. The kyphotic angle is −3° 12months after surgery and solid anterior fusion (continuous trabeculae of bridging anterior osteophytes without halo signs of screws) was achived. But the kyphotic angle is 12 degree and the rod was bended 12 months after surgery
