Since 1986, 19 patients with 21 fractures of the thoracic and lumbar spine have been treated with the AO Internal Spinal Skeletal System. Of these fractures, 17 were burst fractures, 2 were seatbelt fractures and 2 were fracture-dislocations. All the patients in the series had a minimum follow-up of 12 months. There were 4 important losses of correction and two deep infections. In the majority of patients the postoperative reduction deteriorated during follow-up. The addition of 1 or 2 DTT appears to give the system more stability.
自1986年以来，19例患有21处胸腰椎骨折的患者接受了AO脊柱内固定系统治疗。这些骨折中，17例为爆裂骨折，2例为安全带骨折，2例为骨折脱位。该系列所有患者的最短随访时间为12个月。出现4例明显的矫正丢失和2例深部感染。在大多数患者中，术后复位在随访期间恶化。增加1或2枚双螺纹钛钉似乎能使该系统更稳定。
