Abstract:
Objective To evaluate the outcome of reoperation(after I stage anterior/posterior operation)for thoracolumbar fractures combined with kyphosis and spinal cord injury. Methods A retrospective study was done on the medical records of 12 patients who underwent two-stage decompression with kyphosis and neurologic deficit due to single-stage approach(anterior or posterior) operation of thoracolumbar fractures combined with spinal cord injury between January 2005 and April 2009.There were 9 males and 3 females,at mean age of 34.6 years(range,19-57 years).According to the Denis classification,there were five patients with burst fractures,five with compression fractures and two with fracture dislocation.All the patients had couns medullaris injury.Of all the patients,five underwent one stage anterior approach surgery and the others underwent posterior approach operation.All the patients had vailous degrees of neurological symptoms.The patients treated with one stage anterior surgery were treated with two stage posterior surgery and the patients treated with one stage posterior surgery were treated with the two stage anterior operation.The mean interval from one stage operation to two stage decompression was 13.4 months(range,12-18 months).The radiologic,neurologic and functional outcomes were assessed through observation of the Cobb angle,Frankel spinal cord injury grading and Japanese Orthopaedic Association Scores(JOA). Results AIl the patients were followed up for mean 25 months (12-48months),which showed primary healing of the incisions in all the patients.The average anterior and posterior heisht of the vertebrae wers corrected from preoperative 42.6%and 70.5%to postoperative 92.5%and 95.7%and to 87.3%and 92.2%at the final follow-up respectively.Neurologic status was improved at least one Frankel grade in the patients who had preoperative incomplete paraplegia.The Cobb angle was corrected from preoperative 36.3°to postoperative 5.8°and to 5.9°at the final follow-up(P<0.05).No patient had any notable loss of correction between discharge and final follow-up.According to JOA coring,the results were excellent in nine patients,good in two and fair in one,with excellence rate of 92%. Conclusions Two stage decompression for epiconus and cauda equina syndrome resulted from one stage approach(anterior or posterior)operation of thoracolumbar fractures combined with spinal cord injury call attain satisfactory correction of the kyphosis and nerve decompression as well as various degrees of nerve function recovery.
