A modified Gaines procedure for spondyloptosis

Irreducible L5/S1 Spondyloptosis in Over 20 Years After Neglected Trauma Treated with Modified Grob's Technique - Case Report

Introduction

Spondyloptosis, characterized by complete slippage of the upper vertebral body relative to the lower vertebral body, is an exceedingly rare condition. Typically, it occurs as a result of a high-energy injury and is promptly managed. It is uncommon for a patient to present to a spinal surgery unit several decades after the initial incident.

Case Report

In this case report, we describe the case of a 62-year-old man who experienced a lumbosacral injury from a fall twenty years prior to seeking treatment. The patient had multiple comorbidities, including obesity and internal medicine conditions. He presented with severe back pain radiating to the lower extremities, accompanied by significant neurogenic chroma and lower extremity weakness. Imaging studies revealed spondyloptosis at the L5/S1 level, along with bony fusion and spinal canal stenosis at the L3/L4 level.

Conclusion

The patient underwent surgical intervention using Grob's direct pediculo-body fixation technique. The postoperative period was uneventful, and over the course of one year of follow-up, the patient experienced a resolution of symptoms and significant improvement in functional capacity.

Acute Traumatic Spondyloptosis: A Case Report

Acute traumatic spondyloptosis (ATS) is a rare condition in the orthopedic literature, with few cases reported. We present a case of ATS in a 35-year-old Hispanic male with multilevel injury, without neurological deficits at the time of injury. The patient was treated in a two-stage method consisting of combined anterior and posterior spinal decompression and fusion. At the six-month follow-up, the patient had no motor/sensory deficits, he remained stable during the one-year period. Conclusion: ATS is rarely seen in patients without neurological deficits on presentation. Although surgical intervention presents significant risks of iatrogenic neurologic compromise, surgical fixation is warranted.

Posterior-Only Vertebral Column Resection for Fused Spondyloptosis

STUDY DESIGN

Retrospective review.

OBJECTIVES

To describe 3 cases of a posterior-only vertebral column resection (pVCR) for the treatment of spondyloptosis in the setting of prior spinal fusions.

SUMMARY OF BACKGROUND DATA

Lumbosacral spondyloptosis is a rare spinal deformity with a number of surgical options, none of which demonstrate clear superiority. The use of an L5 vertebral column resection, via combined anterior and posterior approaches, to restore lumbosacral alignment has been described though is accompanied by high rates of neurological deficit.

METHODS

Review of 3 cases of spondyloptosis with prior spinal fusions in which a staged pVCR was used for deformity reconstruction.

RESULTS

Three females, ages 39, 54, and 28, developed spondyloptosis with progressive lumbosacral kyphosis and sagittal malalignment after prior in-situ posterolateral spinal fusions. All were treated with staged pVCRs. At ultimate follow-up, imaging revealed improvement in sagittal balance of 6.1 cm (56%) in the 39-year-old and 12 cm (67%) in the 54-year-old, 21.1 cm (92%) in the 28-year-old. All patients had improvement in outcome scores with perfect satisfaction scores despite the 54-year-old having a persistent right foot drop.

CONCLUSION

Posterior-only VCR for spondyloptosis is a technically demanding surgical option offering significant radiographic and clinical improvement, but carries a risk for L5 nerve root deficit as in any spondyloptosis treatment.
