Spondyloptosis refers to complete dislocation of a vertebral body onto another. The L5–S1 level is frequently affected. As this condition is rare, few published reports describing its clinical features and surgical outcomes exist, especially in the pediatric patient population. The authors report the presentation, pathological findings, and radiographic studies of a 2-year-old girl who presented to Texas Children's Hospital with a history since birth of progressive spastic paraparesis. Preoperative CT and MRI showed severe spinal cord compression associated with T11–12 spondyloptosis. The patient underwent a single-stage posterior approach for complete resection of the dysplastic vertebral bodies at the apex of the spinal deformity with reconstruction and stabilization of the vertebral column using a titanium expandable cage and pedicle screws. At the 12-month follow-up, the patient remained neurologically stable without any radiographic evidence of instrumentation failure or loss of alignment. To the best of the authors' knowledge, there have been only 2 other children with congenital thoracolumbar spondyloptosis treated with the above-described strategy. The authors describe their case and review the literature to discuss the aggregate clinical features, surgical strategies, and operative outcomes for congenital thoracolumbar spondyloptosis.

“…In addition to our 6 cases, we discovered an additional 26 patients in the literature whom we felt reasonably met the defining features of CVD-translational dislocation at a single vertebral level without other significant vertebral malformations [1,3,[9][10][11]. Although we believe these are all patients with CVD, radiographs are not available for every patient and there remains the possibility that some may not have had CVD.…”

“…Unfortunately, although this is a simple and readily applicable definition, the literature dealing with CVD and other vertebral anomalies is confusing. Patients having different types of vertebral malformations have been variably grouped together using such terms as CVD, 'the congenital dislocated spine', 'segmental spinal dysgenesis' (SSD), 'congenital spinal stenosis', 'congenital duplication of the spinal canal', 'congenital kyphosis and subluxation of the thoracolumbar spine due to vertebral aplasia', 'medial spinal aplasia' (MSA), and 'congenital lumbar kypholisthesis' [1][2][3][4][5][6][7][8][9]. Whereas some authors have proposed distinct anatomical and radiographic criteria for some of these disorders [1,6,8], others have suggested that all of these terms describe a single fundamental malformation [2].…”

The Embryogenesis of Congenital Vertebral Dislocation: Early Embryonic Buckling?

Congenital vertebral dislocation (CVD) is a rare congenital spinal malformation characterized by a translatory or rotatory vertebral displacement, or both, at a single level, that results in an abrupt angulation of the neural canal. The more caudal vertebra is dysplastic and appears at first glance to be posteriorly dislocated into the vertebral canal as a posterior hemivertebra, but is actually well aligned with the more caudal vertebral column. Unfortunately, the present classification of complex congenital vertebral anomalies is confusing, and CVD has been grouped together with other congenital vertebral malformations under the terms ‘segmental spinal dysgenesis’, ‘medial spinal aplasia’, and others. Moreover, a putative embryonic mechanism has never been proposed for CVD. Based upon our experience with 6 children and a critical review of the literature, we identify CVD as a distinct entity having characteristic anatomical features. We propose a novel putative embryonic mechanism – early embryonic ‘buckling’ – which likely occurs by the 6th embryonic week, prior to the period of axonal outgrowth and the beginning of vertebral chondrification.

“…Because of this, before its recognition as a pathological entity in 1988,[1] various terms had been applied to this complex pathological picture, like “Congenital kyphosis and subluxation of the thoracolumbar spine due to vertebral aplasia”[2] or “Congenital spinal stenosis”[3] amongst others. Furthermore, in addition to the bony anomalies there is frequent association of intradural pathology like tethered cord and/or syringomyelia.…”

Segmental spinal dysgenesis associated with occult dysraphism: Considerations on management strategies

Segmental spinal dysgenesis is a rare and challenging entity especially when associated with occult dysraphism. Experience with a female patient followed during a period of 10 years spanning from 5 to 15 years of age is reported. During that period the girl underwent three spinal operations consisting in one decompression and spinal cord untethering, one posterior instrumented fusion and a spinal cord re-untethering. Clinical and radiological features are discussed and considerations on optimization of management strategies are made.

Congenital kyphosis and subluxation of the thoraco-lumbar spine due to vertebral aplasia

Abstract: Vertebral body aplasia or hypoplasia leads to rapidly progressive spinal deformity and neurologic defects when unrecognized in infancy. Four patients with this unusual defect are described.
