Cases: We present 2 cases (19- and 40-year-old women) of lumbosacral spinal deformity with sacroiliac joint destruction. Reconstruction surgery using a fibular strut autograft was performed in both patients, and spinal reconstruction and fusion were successfully maintained without bone resorption for at least 7 years.
Conclusion: This is the first report of reconstructive surgery using a fibular strut bone graft for lumbosacral deformity with destruction of the sacroiliac joint in patients with neurofibromatosis type 1 (NF-1). These findings suggest that reconstruction with a fibular strut autograft is useful for lumbosacral spinal deformity that includes destruction of the sacroiliac joints in NF-1.
