C1-2 rotatory subluxation as a presenting sign in juvenile rheumatoid arthritis.

Study Design: Case report.

Introduction: Juvenile rheumatoid arthritis (JRA) typically presents with fever, rash, anterior uveitis, and/or joint pain. We present three cases with initial torticollis due to rotatory subluxation of C1-C2 as an initial sign of JRA.

Vitamin D levels and pain outcomes in adolescent idiopathic scoliosis patients undergoing spine fusion.

Purpose: Prior research has indicated adolescent idiopathic scoliosis (AIS) patients have lower bone mineral density and lower vitamin D levels than healthy peers. Vitamin D deficiency has been associated with higher levels of pain. This study investigated whether vitamin D-deficient AIS patients had higher pain before or immediately after posterior spine fusion (PSF) surgery.

Scoliosis with Chiari I malformation without associated syringomyelia.

Purpose: Many patients with presumed idiopathic scoliosis are found to have Chiari I malformation (CM-I) on MRI. The objective of this study is to report on scoliosis progression in CM-I with no syringomyelia.

Methods: A retrospective review of patients with scoliosis and CM-I was conducted from 1997 to 2015.

Risk factors for gastrointestinal complications after spinal fusion in children with cerebral palsy.

Design: Prospective cerebral palsy (CP) registry review.

Objectives: (1) Evaluate the incidence/risk factors of gastrointestinal (GI) complications in CP patients after spinal fusion (SF); and (2) investigate the validity of the modified Clavien-Dindo-Sink classification.

Background: Perioperative GI complications result in increased length of stay (LOS) and patient morbidity/mortality.

Chiari I malformations with syringomyelia: long-term results of neurosurgical decompression.

Study Design: Retrospective case series.

Objectives: The objective was to assess the long-term outcomes on scoliosis following Chiari-I (CM-I) decompression in patients with CM-I and syringomyelia (SM). A secondary objective was to identify risk factors of scoliosis progression.
