Scoliosis

BACKGROUND: ScoliScore is a DNA-based prognostic test, designed and used to help to predict the risk of curve progression in patients with adolescent idiopathic scoliosis. The role of this test in clinical practice remains unclear as the published results of the ScoliScore have not been validated independently. The purpose of this study was to determine if the ScoliScore effectively predicted the risk of curve progression in patients with mild and moderate adolescent idiopathic scoliosis in two urban academic medical centers...

BACKGROUND: The Classification for Early-onset Scoliosis (C-EOS) was developed by a consortium of early-onset scoliosis (EOS) surgeons. This study aims to examine if the C-EOS classification correlates with the speed (failure/unit time) of proximal anchor failure in EOS surgery patients. METHODS: A total of 106 EOS patients were retrospectively queried from an EOS database. All patients were treated with vertical expandable prosthetic titanium rib and experienced proximal anchor failure...

OBJECTIVES: This systematic review was conducted to examine the effects of exercise on spinal deformities and quality of life in patients with adolescent idiopathic scoliosis (AIS). DATA SOURCES: Electronic databases, including PubMed, CINAHL, Embase, Scopus, Cochrane Register of Controlled Trials, PEDro, and Web of Science, were searched for research articles published from the earliest available dates up to May 31, 2015, using the key words "exercise," "postural correction," "posture," "postural curve," "Cobb's angle," "quality of life," and "spinal deformities," combined with the Medical Subject Heading "scoliosis...

BACKGROUND: Quality improvement in orthopaedic surgery has received increasing attention; however, there is insufficient information available about the perioperative safety of many common pediatric orthopaedic procedures. This study aimed to characterize the incidence of adverse events in a national pediatric patient sample to understand the risk profiles of common pediatric orthopaedic procedures, and to identify patients and operations that are associated with increased rates of adverse outcomes...

BACKGROUND: Classification systems can be useful tools for clinical care and research but must be proven as reliable. The purpose of this study was to evaluate the interobserver and intraobserver reliability of the Classification of Early Onset Scoliosis (C-EOS) scheme. METHODS: After IRB approval, 50 cases were drawn from a prospectively collected database of patients with EOS. Cases were selected using a stratified randomization scheme based on etiology. These cases were used to create an internet survey that was sent to pediatric orthopaedic faculty, research coordinators, and fellows involved in EOS care and research...

STUDY DESIGN: Retrospective review of prospective data. OBJECTIVE: To define optimal postoperative coronal parameters after selective thoracic fusions (STFs) and to test these parameters against recommended criteria for when to perform an STF. SUMMARY OF BACKGROUND DATA: Previous studies have provided recommendations for when STF should be performed; however, clear parameters for target outcomes are lacking. METHODS: Patients with Lenke 1C to 4C curves with adolescent idiopathic scoliosis from a multicenter database who underwent STF with minimum 2 years of follow-up were included...

BACKGROUND: Anterior-posterior spinal fusion (APSF) is the traditional treatment for patients with idiopathic scoliosis and open triradiate cartilage (OTRC). Our goals were to assess whether posterior-only spinal fusion (PSF) with pedicle screws can halt deformity progression as effectively as APSF in patients with OTRC, and whether selection of the distal fusion level influences curve progression. METHODS: We studied a prospective multicenter database to identify all children with 2-year radiographic and clinical follow-up who were 11 years or younger with Risser grade 0 and OTRC who were treated with (1) PSF (OTRC-PSF group, N=20); or (2) APSF (OTRC-APSF group, N=9)...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To determine predictors of and 30-day complications associated with blood transfusion volume after posterior spinal fusion for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: Posterior arthrodesis is a common procedure performed for AIS, and patients frequently require perioperative blood transfusions. Few studies, however, have examined the rates and potential complications associated with blood transfusion volume...

STUDY DESIGN: Retrospective case series. OBJECTIVE: To investigate the safety and efficacy of spine-shortening osteotomy for congenital scoliosis with tethered cord. SUMMARY OF BACKGROUND DATA: Conventional surgery for congenital scoliosis associated with tethered cord risks the complications of detethering. Spine-shortening osteotomy holds the potential to correct scoliosis and decrease spinal cord tension simultaneously without an extra detethering procedure, but no data on this issue is available...

One hundred and thirty-three curves in 102 patients who were followed for an average of 40.5 years were evaluated to quantitate curve progression after skeletal maturity and for prognostic factors leading to curve progression. Sixty-eight per cent of the curves progressed after skeletal maturity. In general, curves that were less than 30 degrees at skeletal maturity tended not to progress regardless of curve pattern. In thoracic curves the Cobb angle, apical vertebral rotation, and the Mehta angle were important prognostic factors...

While attempts to understand them better and treat them more effectively, early-onset deformities have gained great pace in the past few years. Large patient series with long follow-ups that would provide high levels of evidence are still almost non-existent. That there is no safe treatment algorithm defined and agreed upon for this patient population continues to pose a challenge for pediatric spine surgeons. In this review, authors who are well known for their research and experience in the treatment of early-onset scoliosis (EOS) have come together in order to answer those questions which are most frequently asked by other surgeons...

BACKGROUND: Infection after spinal fusion for scoliosis is a commonly reported complication. Although techniques in paediatric spinal fusion have improved with regard to infection prophylaxis, postoperative infection rates range from 0.4% to 8.7%. INFECTION RATES AND CAUSATIVE FACTORS: The rate of infection in surgery for adolescent idiopathic scoliosis (AIS) has ranged from 0.9% to 3%. The rate of infection in spinal surgery for deformity related to myelomeningocele has been reported to be from 8% to 24%...

Appropriate levels for instrumentation and fusion in scoliosis have been a matter of debate among surgeons since the introduction of operative management of this deformity. We set out to examine the hypothesis that the amount of correction achieved in all planes during surgical instrumentation of a curve should be less than, or comparable to, the degree of correction attainable at any non-instrumented adjacent curve. An algorithm was designed to facilitate preoperative planning and intraoperative performance of spinal fusion procedures in the management of scoliosis...

BACKGROUND: Scoliosis is present in 3-5% of the children in the adolescent age group, with a higher incidence in females. Treatment of adolescent idiopathic scoliosis is mainly dependent on the progression of the scoliotic curve. There is a close relationship between curve progression and rapid (spinal) growth of the patient during puberty. However, until present time no conclusive method was found for predicting the timing and magnitude of the pubertal growth spurt in total body height, or the curve progression of the idiopathic scoliosis...

Scoliosis may be a spinal manifestation of underlying disease and although most cases of scoliosis are idiopathic, imaging plays a very important role in determining the underlying aetiology and in monitoring the changes of the deformity that take place with growth. As a clinical problem scoliosis may present directly to the radiology department through a primary healthcare referral, or it may be referred from the paediatric, orthopaedic, spinal and neurosurgical hospital services. Growth affects all types of scoliosis irrespective of cause...

Fusion levels are selected with the goal of having a balanced physiologic spine on the postoperative films. We have proposed an algorithm for selecting fusion levels based on the King-Moe scoliosis classification scheme and the flexibility of a compensatory curve. We propose the acronym TEAMS as a pneumonic. Curve type defines the region of the spine to be fused. The ends of the Cobb measurement around the region are the temporary endpoints. The endpoints are extended to avoid an apex due to the sagittal or frontal planes...

STUDY DESIGN: Use of a rule-based automated algorithm to determine sources of variability in radiographic classification. OBJECTIVES: To determine whether unambiguous rules encoded in a computer program would ensure reliable classification. SUMMARY OF BACKGROUND DATA: Reliability problems have been identified in classifications used in surgical planning for patients with thoracic idiopathic scoliosis, but the sources of unreliability are not understood...

Children with early onset scoliosis typically present before age 5 years. Radiographic criteria help to distinguish progressive cases from those that will spontaneously resolve. Severe cardiopulmonary problems may occur in untreated progressive cases. A comprehensive evaluation should be performed to identify commonly associated conditions, such as plagiocephaly, congenital heart disease, inguinal hernia, and hip dysplasia. For curves >20 degrees , magnetic resonance imaging of the neural axis is indicated to rule out occult central nervous system lesions...
