English Abstract:

  【Abstract】 Objective：To evaluate the diagnosis and surgical treatment of spinal osteochondroma.Method：A retrospective review of 21 patients with spinal osteochondroma treated surgically in our hospital from January 1995 to June 2006 was performed.There were 14 males and 7 females with the mean age at diagnosis of 35.0 years old（range，8-61 years old）.19 cases had lesions solitary and 2 multiple. 14 lesions were located in the cervical spine，5 in the thoracic spine，and 2 in the lumbar spine；All the lesions had posterior elements involved.15 patients presented with neurologic deficits，3 with local pain or discomfort，and 3 with painless mass.Preoperative Frankel system showed grade C in 1 case，grade D in 8 cases and grade E in 12 cases.All patients underwent surgical procedures.The surgical time，blood loss，preoperative symptoms，tumor recurrence and metastasis，as well as the status of spinal stability were followed-up and reviewed.Result：The mean surgical time was 130mins（range，45-360mins）；the average intraoperative blood loss was 510ml（range，20-2000ml）.All patients had Frankle score improved to grade E after operation.17 cases were followed up for an average of 7.1 years（range，4-14 years），no tumor recurrence was noted.Conclusion：CT and/or MRI is critical for final diagnosis.Surgery is indicated for long-term neck pain，neurological defect，and/or lesion progression recently.Complete resection of the tumor is reliable.
