Assessment of three year experience of a strategy for patient selection and timing of operation in the management of acute thoracic and lumbar spine fractures: a prospective study

The purpose of this article is to report experience gained over three years of the use of a protocol for patient selection and timing of operation for acute thoracic and lumbar fractures.At admission, all patients underwent neurological and imaging exams. All patients with a spinal cord lesion scored as ASIA A at any level inferior to T10 and as ASIA B, C or D at any level, were categorized as emergency and operated on within eight hours from trauma. ASIA A cases in the T1-T10 tract and ASIA E cases at any level were treated in the ordinary operative work schedule.Ninety-four patients with surgically treated lumbar or thoracic fractures took part in this study. On the imaging studies, 12 patients were classified as A, 50 as B and 32 as C following the AO classification. At the neurological exam, 39 patients were scored as ASIA A, nine as B, six as C, two as D and 38 as E. At follow-up, of the 39 patients scored as ASIA A, 13 (33%) improved at least one grade and of the 17 scored as ASIA B, C or D, 11 (64.7%) improved. None of the 38 patients scored as ASIA E deteriorated.The findings show that the strategy in the protocol was safe and followed by satisfactory rates of neurological outcome. Larger prospective studies, preferably randomized, are needed to establish definitively its place in the management of patients with spinal injury.
