Dysplasia of C-1 and craniocervical instability in patients with Shprintzen-Goldberg syndrome. Case report and review of the literature.

Shprintzen-Goldberg syndrome is a rare connective tissue disorder characterized by marfanoid habitus and additional dysmorphic stigmata. Craniocervical anomalies occur in fewer than 30% of cases. Serious vertebral instability can also occur, albeit rarely. The authors report on the first patient treated with surgical fusion at the craniocervical junction because of a C-1 dysplasia and severe instability. The skeletal and cardiovascular anomalies that can pose additional problems for surgical treatment and perioperative care are discussed in detail.
