Abstract:
Objective To investigate the clinical charactistics,diagnosis,treatment options and surgical efficacy of spinal osteoblastoma.Methods From May 2007 to May 2016,the clinical manifestations,imaging data,diagnosis,treatment and prognosis of 11 patients with spinal osteoblastoma were retrospectively reviewed.There were 7 males and 4 females.The age ranged from 15 to 44 years old with the average of 27.5 years.Two lesions were involved in cervical spine and 6 lesions were located in thoracic spine.The other 3 cases was in lumbar spine.All patients suffered from local pain.Four patients had neurological deficiency,with 3 suffering radicular pain and 1 suffering incomplete paraplegia (Frankel C).Four patients were staged as Enneking 2 and treated by intralesional curettage.Seven patients were staged as Enneking 3.Accordingly,4 patients were treated by expanded excision with single posterior approach and 1 patient was treated by expanded excision with combined anterior and posterior approach.The other 2 patients were treated by piecemeal total vertebrectomy with single posterior approach.The pain release,neurological recovery and tumor recurrence were evaluated by postoperative follow-up.Results The mean operation time was 3.5 h (range,1.5-7 h) and the average intraoperative blood loss was 800 ml (range,100-3 000 ml).1 patient had cerebrospinal fluid leakage and 2 patients had pleural effusion.No surgical infection was detected in any patient.After surgery,the pain was dramatically relieved in all patients.The radicular pain in 3 patients were relieved and the incomplete paraplegia in 1 patient was recovered to Frankel E.The mean follow-up period was 45.8 months (range,12-117 months).Recurrence occurred in 1 case of cervical 7 and thoracic 1 spine leison 4 years after the surgery.Another expanded excision of the tumor was conducted for this patient and no recurrence was detected till now.No other cases of recurrence were observed.No loosing or breakage of implantation was detected during the follow-up.Conclusion For Enneking 2 leisons,intralesional curettage was effective.For Enneking 3 leisons,the expanded excision or piecemeal total vertebrectomy were recommended.No matter the excision was intralesional or not,the satisfactory results could be achieved if complete tumor excision could be conducted.
