Low lumbar spinal fractures: management options

Fifty-four patients with low lumbar spinal fractures were retrospectively reviewed. Of these, there were 25 compression fractures, 21 burst fractures, three flexion-distraction fractures and five fractUre-dislocations. Three patients had a complete neurological lesion, 17 Sustained an incomplete neurological injury, and 34 were neurologically intact. Twenty-six patients were treated non-operatively and 28 underwent surgery. All patients were followed up for 1-12 years. Forty-three patients (79.6%) have returned to their former employment or activity level. Four patients had experienced significant improvement but Suffered from some limitation of activity. Five patients were unable to stand up and walk without support although they had some degree of improvement. Two remained completely paralyzed. There were no differences in neurologic function between patients treated non-operatively or operatively (P > 0.05). The patients treated operatively had significantly less pain compared to the patients treated non-operatively (P < 0.01). Because of the unique anatomy and biomechanics, fractures of the low lumbar spine are different from those in the remaining regions of spine. Most compression fractures are stable, and therefore conservative management is indicated. Surgery should be performed in those with burst fractures or flexion-distraction fractures, with severe spinal stenosis or kyphotic deformity, and fracture-dislocation. (C) 2002 Elsevier Science Ltd.
