Spine deformity surgery in patients with Beals syndrome can be effectively performed but does risk revision surgery.

Beals syndrome or congenital contractual arachnodactyly is a rare disorder characterized by multiple joint contractures, Marfanoid body habitus and crumpled ears and has been associated with scoliosis. This study reports a clinical series of patients with Beals syndrome who have had surgical treatment for their spinal deformity. A retrospective review of all patients at a single institution who had a genetically-confirmed diagnosis of Beals syndrome and had surgical treatment for their scoliosis were reviewed for surgical outcome and complications. There were eight patients who had surgery at an average age of 11.5 years, four were female and four had cardiovascular abnormalities requiring treatment. The preoperative coronal Cobb was 82.3° which improved to 42.1°(46.8% correction), and 46.5° (43.5% correction) at final follow-up. Preoperative halo-gravity-traction was used in three patients. Three patients had a posterior instrumentation and fusion (PSFI), 2 a combined anterior/PSFI, 1 had tethering, 1 with PSFI with posteriorly-approached discectomy, and 1 with a PSFI and vertebral column resection. One of the eight patients had a critical intraoperative neuromonitoring event but was normal following appropriate responses and no patient awoke with neurologic deficits. Two had an unplanned return to the operating room for implant dislodgement and each had a successful revision. Scoliosis associated with Beals syndrome can have large curves at the time of surgery and require a variety of surgical approaches to achieve a good result. Revision surgery with return to the operating room is necessary in 25% of patients.
