Idiopathic Scoliosis

The management of spinal deformity is evolving at a very rapid pace. Many of the teachings and tenets accepted as dogma in the recent past have gone the way of the medicinal leech, as our understanding of the natural history and biomechanics of scoliosis and kyphosis has expanded. Shady Grove Adventist Hospital offers the patient with spinal deformity the entire spectrum of appropriate interventions, from composite thermoplastic bracing to state-of-the-art spinal implants and intraoperative spinal cord monitoring. |
- there apparently being not much in the way of utilization review back then! The first spinal fusion for scoliosis was performed in New York by Russell Hibbs in 1914. The results of fusion surgery were generally poor until the advent of internal fixation with the Harrington rod, in the early 1960s. In the past decade, an ever-increasing array of instrumentation systems has been developed, to better realize the goals of improved safety, curve correction, fusion rate and postoperative patient mobilization. ETIOLOGY Over the last 75 years, the cause of idiopathic scoliosis has been sought in investigation of every area that could relate to the deformity. Research has focused on genetics, growth and the endocrine system, postural equilibrium and the central nervous system, all structural elements of the spine, biomechanics and collagen metabolism. Genetics plays an important role in the development of idiopathic scoliosis. It is eight times more common in girls, and 10 times more likely to be found in close family members. Its transmission can't be defined in classic mendelian terms, nor have the gene(s) or biochemical sequences been identified. Further, there is evidence that an abnormality exists in the sensory afferents or in the brain stem, disturbing the reflexes that control spinal posture. continued on page 2 |
