Delayed atlantoaxial rotatory dislocation in a child with Crohn's disease: illustrative case.

Background: Atlantoaxial rotatory dislocation (AARD) in children may be caused by neck trauma or an upper respiratory tract infection. Here the authors describe the very rare association between inflammatory bowel disease and AARD in a child.

Observations: A 7-year-old girl presented with an 11-month history of torticollis that occurred spontaneously without a trauma context.

Surgical correction of a previously operated juvenile idiopathic scoliosis with crankshaft phenomenon: an illustrative case report.

Background: Crankshaft phenomenon secondary to posterior fusion for scoliotic deformity at a young age has become rare and its management can be very challenging.

Case Description: We report the case of an 11-year-old girl who has been complaining of a progressively increasing hump in her back with waist and shoulders asymmetry during the past 6 months. Three years prior to presentation, she underwent in another institution posterior correction fusion from T3 to L3 for a juvenile idiopathic scoliosis with a Cobb angle of 60°.
