“…Eleven studies with 18 involved patients have been previously reported [3][4][5][6][7][8][9][10][11][12][13] (Table 1). These patients were remarkably similar: there were 10 males and 8 females with a mean age at presentation of 14.1 years (range: 5 to 41 y).…”

“…1,2 Although enlargement of the intervertebral foramina on the convexity of the curve can result in subluxation or penetration of a rib head into the spinal canal, it is rare with only 18 cases reported in the orthopaedic literature (Table 1). [3][4][5][6][7][8][9][10][11][12][13] We present a case of an adolescent male with NF-1 and severe dystrophic kyphoscoliosis with subluxation of 2 adjacent rib heads into the spinal canal, one of which was not apparent on the initial preoperative imaging.…”

“…обсуждение пенетрация ребром позвоночного канала (пРпК) при НФ-1 не относится к числу живо-трепещущих проблем оперативной вертебро-логии, поэтому количество публикаций, по-священных ее диагностике и соответствующей хирургической тактике, весьма ограничено. В англоязычной литературе после целенаправ-ленного поиска нам удалось обнаружить лишь 14 работ такого рода, содержащих описание 44 клинических наб людения [3][4][5][6][7][8][9][10][11][12][13][14][15][16].

“…Большинство авторов предпочитают сочетание вентрального и дорсального доступов -вен-тральный спондилодез, дорсальная инструмен-тальная коррекция и спондилодез, резекция смещенного в канал ребра [3-10, 11, 13, 15, 16]. Часть из них выполняет резекцию ребра из дорсального доступа с ламинэктомией на соот-ветствующем уровне, позволяющей визуально контролировать устранение патологической ситуации [4,6,9,15,16]. В одном из описан-ных N. yalcin с соавторами случаев операция была выполнена только из вентрального дос-тупа: 6-летнему мальчику после аннулотомии на пяти уровнях имплантированы растущие стержни [16].…”

Background. Rib penetration into the spinal canal in patients with scoliosis secondary to neurofibromatosis type-1 (NF-1) was described in a relatively small number of publications, though it’s common in clinical practice and not always diagnosed.Materials. The authors report on an adolescent male with NF-1 left thoracic kyphoscoliosis and rib head protrusion into spinal canal with mild initial neurological deficit.Results. A 14-year-old male patient with NF-1 and 68 degrees left thoracic scoliosis and 65 degrees kyphosis was undergoing treatment at the authors’ institution.Preoperative CT scans demonstrated protrusion of the left T11 rib head into the spinal canal on the convexity of the curve, without spinal cord compression. Surgical procedure for resection of the rib head and correction of the spinal deformity was performed which allowed to achieve good deformity correction. The authors also observed almost complete restoration of sensitive functions.Conclusion. Rib head protrusion into the spinal canal can occur in cases of spine deformities with NF-1. If present, the imaging findings should be carefully reviewed for appearance of such lesion that may be obscured by the limitations of CT in the context of a dysplastic spinal deformity.

BackgroundIntraspinal rib head dislocation is an important but under-recognized consequence of dystrophic scoliosis in patients with neurofibromatosis 1 (NF1).ObjectiveTo present clinical and imaging findings of intraspinal rib head dislocation in NF1.Materials and methodsWe retrospectively reviewed clinical presentation, imaging, operative reports and post-operative courses in four NF1 patients with intraspinal rib head dislocation and dystrophic scoliosis. We also reviewed 17 cases from the English literature.ResultsIn each of our four cases of intraspinal rib head dislocation, a single rib head was dislocated on the convex apex of the curve, most often in the mid- to lower thoracic region. Cord compression occurred in half of these patients. Analysis of the literature yielded similar findings. Only three cases in the literature demonstrates the MRI appearance of this entity; most employ CT. All of our cases include both MRI and CT; we review the subtle findings on MRI.ConclusionAlthough intraspinal rib head dislocation is readily apparent on CT, sometimes MRI is the only cross-sectional imaging performed. It is essential that radiologists become familiar with this entity, as subtle findings have significant implications for surgical management.
