Brief Summary:
This study aimed to investigate the prevalence and clinical significance of sleep-disordered breathing (SDB) in children with mild-moderate idiopathic scoliosis (IS).

Condition or disease
Scoliosis Idiopathic Sleep Disordered Breathing Obstructive Sleep Apnea

Detailed Description:

Idiopathic scoliosis (IS) is the most common pediatric musculoskeletal disorder that causes a three-dimensional spinal deformity affecting 2 to 4% of adolescent subjects. It can be progressive (in 3 out of 10 cases) and severe involving serious effects (spine pain, cardiopulmonary compromise, deformed torso, psychosocial issues) and heavy treatments (corset, surgery). However, there is still no reliable criteria to predict the occurrence and progression of IS, while the etiology of IS remains unclear.

Sleep-disordered breathing (SDB) in children is a common condition characterized by recurrent events of upper airway obstruction during sleep. The major symptom is snoring or noisy breathing. Preliminary evidence suggests that SDB in children is associated with low bone mass and postural stability, which might be mechanisms in the development of scoliosis. However, the influence of SDB on the progression of IS remains unknown.

To fill those gaps, investigators will perform a prospective, unrandomized, observational cohort study to determine the prevalence and significance of SDB in children with mild-moderate IS. All subjects will be screened with a designated sleep questionnaire (PSQ), and children with either severe daytime sleepiness or frequent snoring or any degree of sleep pause will be requested to undergo further evaluation and an overnight polysomnography (PSG). Routine follow-up visits will be scheduled 6 months apart up to 24 months to assess the curve progression of scoliosis.

Idiopathic scoliosis with untreated and treated sleep-disordered breathing
IS without SDB, controls
Idiopathic scoliosis without sleep-disordered breathing, control group



Primary Outcome Measures :
  1. Scoliosis Curve Progression [ Time Frame: Routine follow-up visits will be scheduled 6 months apart up to 24 months ]
    A long standard standing whole spine radiograph will be used for measuring curve size in terms of Cobb angle according to the standard Cobb method

  2. Vertebral Rotation [ Time Frame: Routine follow-up visits will be scheduled 6 months apart up to 24 months ]
    Grades of vertebral rotation will be measured by the Nash-Moe method using the same spine radiograph


Secondary Outcome Measures :
  1. Sleep Measurements [ Time Frame: Routine follow-up visits will be scheduled 6 months apart up to 24 months ]
    Sleep questionnaire with or without further PSG evaluation

  2. Body mass index [ Time Frame: Routine follow-up visits will be scheduled 6 months apart up to 24 months ]
    Changes in height, weight and body mass index
