The management of idiopathic scoliosis in the skeletally immature patient can be challenging. Posterior spinal fusion and instrumentation is indicated for severe scoliosis deformities. However, the skeletally immature patient undergoing posterior fusion and instrumentation is at risk for developing crankshaft deformities. Read More

Purpose: Adolescent idiopathic scoliosis (AIS) is the most common form of scoliosis and occurs in children between 10 to 18 years old, during periods of growth spurts and puberty changes. In patients with central precocious puberty (CPP), due to early growth spurt, AIS is expected to develop before 10 years of age. Both AIS and CPP are more common in girls than in boys. Read More

Background Adolescent idiopathic scoliosis (AIS) is a potentially progressive deformity, and early detection is crucial for timely intervention. However, the methods and criteria justifying screening for pediatric scoliosis remain controversial. We have, therefore, independently developed a Digital Moiré (DM) as a tool for scoliosis screening. Read More

Background: The impact of surgery on the quality of life of adolescents with idiopathic scoliosis (AIS) remains to be clarified as most of the studies are retrospective and few include quality of life questionnaires completed in the pre- and postoperative periods.

Methods: Operated patients with AIS who completed preoperative and postoperative SRS-22 questionnaires were selected for evaluation. The demographic data were collected and quality of life improvement was assessed by comparing deviation to the means with standard deviation at both moments. Read More

Iowa Orthop J 2019 ;39(2):62-65

University of Iowa Department of Orthopaedics and Rehabilitation, Iowa City IA USA.

Background: Adolescent idiopathic scoliosis (AIS) is defined as a lateral curvature of the spine of unknown etiology with a Cobb angle of greater than 10 degrees with vertebral rotation. Bracing, specifically with a rigid thoracolumbosacral orthosis (TLSO), decreases the risk of curve progression to over 50 degrees, the threshold for surgical intervention. Some authors have suggested that 30-50% in-brace correction of the Cobb angles is required to prevent significant curve progression. Read More

Idiopathic scoliosis is one of the most difficult problems of contemporary orthopaedics and physiotherapy, and its unknown etiology hinders initiation of effective causative therapy. A tendency for progression of scoliosis, and failure of many conservative treatment methods stimulated a search for new and more effective methods which will not only stop a progress of the deformation, but actually correct it. The FED method is a relatively new, but promising method used for conservative treatment of idiopathic scoliosis. Read More

Background: In patients with Marfan syndrome (MFS), surgical correction of spinal deformities with hooks and/or pedicle screws involves a higher rate of complications than in patients with adolescent idiopathic scoliosis. Therefore, sublaminar instrumentation is often a last resort option. This study wants to assess the ability of sublaminar fixation to achieve three-dimensional scoliosis correction and spine stabilization compared with hook and/or pedicle screw systems. Read More

Idiopathic scoliosis is the largest group of all forms of scoliosis in the growth phase accounting for 80-90%. A distinction is made between idiopathic infantile (0-3 years), juvenile (4-10 years) and adolescent scoliosis (>10 years), depending on the age when scoliosis appears. The treatment depends on the skeletal age, the Cobb angle and the progression behavior of scoliosis. Read More

Objective: Controversy exists regarding the effects of lowest instrumented vertebra (LIV) tilt and rotation on uninstrumented lumbar segments in adolescent idiopathic scoliosis (AIS) surgery. Because the intraoperative LIV tilt from the inferior endplate of the LIV to the superior sacral endplate is not stable after surgery, the authors measured the LIV angle of the instrumented thoracic spine as the LIV angle of the construct. This study aimed to evaluate the effects of the LIV angle of the construct and the effects of LIV rotation on the postoperative uninstrumented lumbar curve and L4 tilt in patients with thoracic AIS.

Background: Both patients with Chiari-I malformation (CIM) with syringomyelia and those with idiopathic syringomyelia (ISm) have a syrinx and can have scoliosis as well. However, there is no literature regarding differences between CIM and ISm in terms of radiographic outcomes and surgical complications after posterior fusion, to our knowledge.

Background: Congenital disorder of glycosylation (CDG) type I is a group of rare disorders caused by recessive mutations in up to 25 genes that impair the N-glycan precursor formation and its transfer to proteins resulting in hypoglycosylation of multiple proteins. Congenital disorder of glycosylation causes multisystem defects usually with psychomotor delay that is diagnosed in the infancy. We aim to supply further evidences supporting that CDG may be underestimated. Read More
