Abstract

BACKGROUND AND IMPORTANCE: Traumatic lateral spondyloptosis, or lateraloptosis, is the complete lateral dislocation of the spine. Reduction in these dislocations presents unique challenges, especially in cases of preserved neurological function. Open techniques carry significant risks of cerebrospinal fluid leak and neurological injury. For traditional spondyloptosis, off-table closed techniques have been described but may result in loss of the reduction when the patient is transferred to the operative table. An on-table closed reduction technique has potential advantages over previously described open reduction or off-table techniques for the treatment of lateraloptosis. CLINICAL PRESENTATION: The authors describe an on-table closed reduction technique for lateraloptosis, presenting an illustrative case in which the technique was applied. This technique is compared with alternative open and off-table reduction techniques described in the literature. The patient had good mechanical and neurological outcomes. At 14 months postoperatively, she is neurologically intact, back to work involving heavy lifting, and has only moderate back pain. CONCLUSION: On-table closed reduction before open fixation should be considered in cases of lateraloptosis, particularly when there is preserved neurological function.
