Reconstruction with fascia lata allograft of the posterior vertebra elements after resection for aneurysmal bone cyst in a child.

Abstract

We report a case of ABC in a child where, after resection of the posterior spinal column of L1, we did a biological reconstruction using a posterior tension band with a segment of fascia lata allograft in tension between T12 and L2. After the long term follow up, X-ray and MRI controls showed a satisfactory alignment of the spine and no local recurrence. The patient now has no sign of spinal instability or deviation, with no kind of discomfort or pain, and has a normal life. In our experience this biological tension band interferes minimally with the growth of the spine, and has a less number of complications in comparison with other more aggressive methods and so is a good option for restoring the stability in young patients with benign spinal tumors that arises on the posterior column without having any kind of potential deviations.
