Traumatic unilateral lumbosacral jumped facet without fracture in a child - presentation of a safe treatment strategy for a rare injury

Abstract

The vast majority of pediatric lumbosacral spondylolisthesis have developmental etiology. Of the very rare type of pediatric lumbosacral facet dislocations, there are only three reported cases of a pediatric unilateral jumped facet injury. All of these cases are associated with fracture dislocation of L5-S1. Hyperflexion with rotation is thought to provoke this uncommon type of spine injury.The authors report the first pediatric patient reported in literature to date with a traumatic unilateral jumped facet at the lumbosacral joint without fracture. The presentation, surgical treatment, hospital course, outcome and management options with the review of the literature is summarized.

Pre-operative images. Panel a) Sagittal CT reconstruction revealed the anterolisthesis of L5 on S1. Axial CT at L5 in Panel b) shows left L5-S1 jumped facet. Panel c) shows the right > left sacroiliac joint dislocation.

Figure 2
Intra-operative images. Panel a) Left L5-S1 jumped facet and rotational anterolisthesis (lines over the spinous processes). Panel b) shows partial reduction during distraction. Panel c) Reduction of the left L5/S1 joint that was fixed into position with posterior instrumentation as shown in Panel d) with re-alignment of the axis (double lines).

Figure 3
Post-operative images. Panel a) Sagittal CT reconstruction following reduction of the anterolisthesis of L5 on S1 with posterior instrumentation. Axial CT scan in Panel b) shows the pedicular screws of L5 with anatomical reduction of the left locked L5-S1 facet joint. In Panel c), AP X-ray of the lumbosacral area with reduced right sacroiliac joint following SI joint screw fixation.
