Idiopathic scoliosis affects 2-5% of adolescents. This study will compare the quality of life, functional outcome, cosmetic result, and the correction of spinal deformity of two instrumentation systems for the treatment of adolescent idiopathic scoliosis.

Condition Intervention Phase
Procedure: Moss Miami Spine Instrumentation System
Procedure: Universal Spine Instrumentation System
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind
Primary Purpose: Treatment
Official Title: Comparing the Moss Miami and Universal Spinal Instrumentation Systems for the Treatment of Adolescent Idiopathic Scoliosis

Further study details as provided by The Hospital for Sick Children:

Primary Outcome Measures:
  • - Quality of life at two years post-surgery, as measured by the self-report Quality of Life Profile for Spinal Disorders

Secondary Outcome Measures:
  • Physical function
  • Deformity, based on clinical exam and spinal radiographs
  • Clinicians' ratings of clinical photographs
  • Surgical outcomes, as measured by blood transfusions, duration of surgery,and length of hospitalization
  • Surgeons' global satisfaction with the instrumentation system
  • Complications of treatment (infection, loss of fixation, neurologic damage, and non-union)

Estimated Enrollment: 126
Study Start Date: September 1997
Estimated Study Completion Date: September 2002

Ages Eligible for Study:   8 Years to 18 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age 8-18 years
  • Diagnosis of idiopathic scoliosis requiring posterior instrumentation and fusion(including those also requiring anterior release with or without anterior instrumentation) who could receive either the USS or the Moss Miami system
  • Patients with scoliosis and an incidental finding of conus < L1-2 disc level, provided they have no symptoms or signs
  • Patients with scoliosis and an incidental finding of a small syrinx (provided the syrinx is non-progressive and does not require neurosurgical treatment)
  • Patients with non-progressive spondylolysis

Exclusion Criteria:

  • Spinal cord abnormalities with any neurologic symptoms or signs
  • Spinal cord lesions requiring neurosurgical interventions, such as hydromyelia requiring Arnold Chiari decompression
  • Primary muscle diseases, such as muscular dystrophy
  • Neurologic diseases (e.g. Charcot-Marie Tooth, Guillain-Barre syndrome, cerebral palsy, or spina bifida, etc.)
  • Primary abnormalities of bones(e.g. osteogenesis imperfecta)
  • Congenital scoliosis
