Management of NF-1 dystrophic scoliosis associated with rib heads dislocation into the spinal canal in neurological intact patients: a systematic literature review.

Purpose: The management of scoliosis and kyphoscoliosis in patients with Type 1 Neurofibromatosis (NF-1) among spinal surgeons is still challenging due to the severity of the deformity especially in dystrophic deformity types. This rapid and progressive condition is likely to be associated with dislocated rib heads into the spinal canal, hence representing a real dilemma on the decision making between its resection versus not resection during the corrective surgery, especially in patients with normal neurological status. The objective of this publication is to discuss the management options in this patient population through a literature review.

Craniocervical spinal instability after type 1 Arnold Chiari decompression: a case report.

To present and describe an unusual case of spinal instability after craniocervical spinal decompression for a type-1 Chiari malformation. Type-1 Chiari malformation is a craniocervical disorder characterized by tonsillar displacement greater than 5 mm into the vertebral canal; posterior fossa decompression is the most common surgical treatment for this condition. Postoperative complications have been described: cerebrospinal fluid leak, pseudomeningocele, aseptic meningitis, wound infection, and neurological deficit.

Juvenile and adolescent idiopathic scoliosis: magnetic resonance imaging evaluation and clinical indications.

The aims of this study were (1) to determine the rate of 'idiopathic' scoliosis associated with neuroanatomical abnormalities of the posterior cerebral fossa (PCF), spinal canal (SC) or central nervous system (CNS), and (2) to identify any clinical, neuro-orthopedic criteria, radiological curve pattern or other variable which could justify magnetic resonance imaging (MRI) as complementary study. Fifty-six patients with juvenile and adolescent scoliosis, were prospectively evaluated with MRI of the PCF and SC. All the patients were categorized into four different groups according to neuro-anatomical abnormalities on MRI (groups A, B, C and D).
