Progressive infantile scoliosis (a type of early onset scoliosis) is a disease that can cause very significant breathing issues, even in early life. A standing lateral view of the thoracic spine is shown in Figure 41. 113 plays. Spine Infections, Tumors, & Systemic Conditions, (SAE07PE.90) It usually begins to develop in the first 6 months of life. It is the only type of scoliosis that is more common in boys. Infantile Idiopathic Scoliosis Juvenile Idiopathic Scoliosis Spondylolysis, spondylolisthesis, back pain, disk disease 0.5-1% 1% 1.5 Pediatric Spondylolisthesis & Spondylolysis Neuromuscular spine 0.5-1% 1% 1.5 Neuromuscular Scoliosis Cerebral Palsy - Spinal Disorders Pathologic Scoliosis Trauma/Sports 33-37% 33-37% 37% 55.5 - Surya Mundluru, MD (ICEOS 2018, #46), Paper #9 Shorter Anesthesia Time and Improved Initial Curve Correction with an Alternative Risser Casting Technique - Robert Lark, MD (ICEOS 2018, #45). According to the American Association of Neurological Surgeons (AANS), scoliosis affects between 2% and 3% of the American population, or about six to nine million people. A rigid thoracic hyperkyphosis defined by, anterior wedging of  >5 degrees across three consecutive vertebrae, narrowed disc spaces, differentiated from postural kyphosis by rigidity of curve (limited correction on extension xrays), most common type of structural kyphosis in adolescents, typical age of onset is from 10-12 years age with small subset adult onset, less common form occurs in thoracolumbar/lumbar region (see below), exact pathophysiology is unknown but several theories, osteonecrosis of anterior apophyseal ring, herniation of disc material leading to loss of anterior disc height, relative osteoporosis leading to compression deformity, altered biomechanics leading to anterior wedging and subsequent growth arrest, most widely accepted theory suggests that the kyphosis and vertebral wedging are caused by a developmental error in collagen aggregation which results in an abnormal end plate, compensatory tightness of anterior shoulder, hamstrings, and iliopsoas muscle, pulmonary issues in curves exceeding 100 degrees, back pain in adults that very rarely limits daily activities (mild curves with a mean of 71 degrees), curves >75 degrees are likely to cause severe thoracic pain, studies suggest at least some progression in 80% of patients but not often to severe deformity, long-standing compensatory lumbar hyperlordosis may lead to lumbar spondylolysis, curve from T1/2 to T12/L1 with apex between T6-T8, Thoracolumbar/lumbar Scheuermann's Kyphosis, curve from T4/5 to L2/3 with apex near the thoracolumbar junction, more likely to be progressive and symptomatic, more irregular end-plates noted on radiographs, less vertebral body wedging, increased kyphosis which has a sharper angulation when bending forwards, may have a compensatory hyperlordosis of the cervical and/or lumbar spine, tight hamstrings, iliopsoas, and anterior shoulder, neurological deficits rare but need full examination, anterior wedging across three consecutive vertebrae >5 degree, spondylolysis on dedicated lumbar films if patient has low back pain, determine sagittal balance by dropping C7 plumb line, supine lateral radiograph with patient lying in hyperextension over a bolster, can help differentiate from postural kyphosis, usually relatively inflexible on bending radiograph, controversial as to whether it is indicated prior to surgery to look for, will show vertebral wedging, dehydrated discs, and, any neurological symptom or deficit warrants evaluation with MRI, most patients fall in this group and can be treated with observation alone, kyphosis 60°-80° most effective in those with growth remaining, usually does not lead to correction but can stop progression, posterior spinal fusion ± osteotomy ± anterior release, less than the typical 10° sagittal plane correction per level given ridigity, technique of the past, rarely done now due to pedicle screw constructs, studies show 60-90% improvement of pain with surgery (no correlation with amount of correction), PSF with dual rod instrumentation +/- anterior release and interbody fusion, current recommendation is to include entire kyphotic Cobb angle and stop distally to include the first stable sagittal vertebra (first vertebra bisected by the posterior sacral vertical line), previously stopped distally at first lordotic disc but had high incidence of distal junctional kyphosis, usually a combination of pedicle screws and hooks, intra canal hooks may be dangerous at apex of curve as they can potentially compress spinal cord, Cantelever - usally two rods placed in top anchors then brought down to bottom pedicle screws, posterior spine shortening technique of Ponte, indicated in stiff curves where correction is needed, done by removing spinous processes at apex, ligamentum flavum, and performing facet joint resection, goal is to obtain correction to final kyphosis of 40-50°, in situ bending usually difficult to do and not helpful, motor and sensory evoked potentials must be monitored intraoperative. 10/16/2019. After the history and physical examination, the next step in evaluating congenital scoliosis is obtaining x-rays. (OBQ16.229) A 2-year old female with infantile idiopathic scoliosis (IIS), a flexible curve with a Cobb angle of 35°, and a RVAD of 25° ... Orthobullets Team Spine - Adolescent Idiopathic Scoliosis; Listen Now 24:40 min. A lateral radiograph shows thoracic kyphosis of 38 degrees. There are significant efforts being made toward identifying the cause of AIS, but to date there are no well accepted causes for this particular type of scoliosis. to infantile scoliosis, finding 69% of patients completely resolved by an average age of 3.5 years when treated early.5 Serial casting technique for EOS relies on the principle of guided growth, improving the deformity in the cast and allowing continued growth of the child Like other types of scoliosis it is characterised by an abnormal sideways S or C curve of the spine. Spine 10-14% Idiopathic scoliosis 0.5-1% 1% 1.5 Kyphosis 0.5-1% 1% 1.5 Scoliosis is defined by the degrees of curvature of the spine, which can be determined with X-rays. This likely represents: Traumatic Spondylolisthesis of Axis (Hangman's Fracture), Occipitocervical Instability & Dislocation, Cervical Lateral Mass Fracture Separation, Extension Teardrop Fracture Cervical Spine, Clay-shoveler Fracture (Cervical Spinous Process FX), Chance Fracture (flexion-distraction injury), Osteoporotic Vertebral Compression Fracture, Ossification Posterior Longitudinal Ligament, DISH (Diffuse Idiopathic Skeletal Hyperostosis), Atlantoaxial Rotatory Displacement (AARD), Pediatric Spondylolysis & Spondylolisthesis, postural improvement exercises and back extensor strengthening, core muscle strengthening for patients with spondylolysis, dual rod instrumentation usually performed, thorascopic anterior discectomy may help avoid morbidity of thoracotomy, but usually not needed, higher than idiopathic scoliosis corrective surgeries, typically due to spinal cord stretching/lengthening (need to ensure there is enough posterior column shortening), neuromonitoring changes warrant reversal of correction, overall incidence of complications does not differ between anterior/posterior versus posterior alone procedure, making proper selection of fusion levels (use the first stable sagittal vertebra), avoid overcorrection (correction should not exceed 50% of original curve), typically secondary to overcorrection and negative sagittal balance, less common that distal junctional kyphosis. It includes, excessive drooling may reflect neurologic condition, dimpling outside of the gluteal fold is usually benign, supine in infants unable to stand (will make curve appear less severe), convex rib head position with respect to the apical vertebrae, phase 2 rib-vertebrae relationship (rib-vertebral overlap), functions to straighten the spine in young patients, in older patients it serves as an adjunctive measure prior to definitive treatment, incompletely corrected curves after Mehta casting, late presenting cases where the spine is still flexible, delay until as close to skeletal maturity as possible, fusion before age 10 years results in pulmonary compromise, Growing rod construct (dual rod or VEPTR). However, the best treatment of IS and JS is still debated and it remains controversial, at least for some aspects. J Bone Joint Surg Am.
