Does anterior shoulder balance in adolescent idiopathic scoliosis correlate with posterior shoulder balance clinically and radiographically?

Purpose: Patients with adolescent idiopathic scoliosis (AIS) often present with a disfiguring shoulder imbalance. Shoulder balance (Sh.B) is of significant importance to the patient's self-perception.

Right adolescent idiopathic thoracic curve (Lenke 1 A and B): does cost of instrumentation and implant density improve radiographic and cosmetic parameters?

In adolescent idiopathic scoliosis (AIS) there has been a shift towards increasing the number of implants and pedicle screws, which has not been proven to improve cosmetic correction. To evaluate if increasing cost of instrumentation correlates with cosmetic correction using clinical photographs. 58 Lenke 1A and B cases from a multicenter AIS database with at least 3 months follow-up of clinical photographs were used for analysis.

Subjective evaluation of treatment outcomes of instrumentation with pedicle screws or hybrid constructs in Lenke Type 1 and 2 adolescent idiopathic scoliosis: what happens when judges are blinded to the instrumentation?

Superiority of pedicle screws over hybrid/hook instrumentation or vice versa in the treatment of Lenke Type 1 and 2 adolescent idiopathic scoliosis (AIS) remains unresolved for moderate curves. Our objective was therefore to compare the assessment of pedicle screw and hybrid/hooks instrumentation with special attention to cosmesis and uninstrumented spine using novel assessment methods. We carried out a retrospective study of radiographs and clinical photos of 40 cases of thoracic AIS between 40 degrees and 70 degrees of Cobb angle Lenke Type 1 and 2, treated with either pedicle screws or hybrid/hooks.

Experience with an online prospective database on adolescent idiopathic scoliosis: development and implementation.

Considerable variability exists in the surgical treatment and outcomes of adolescent idiopathic scoliosis (AIS). This is due to the lack of evidence-based treatment guidelines and outcome measures. Although clinical trials have been extolled as the highest form of evidence for evaluating treatment efficacy, the disadvantage of cost, time, lack of feasibility, and ethical considerations indicate a need for a new paradigm for evidence based research in this spinal deformity.

Anterior thoracoscopic instrumentation in adolescent idiopathic scoliosis: a systematic review.

Study Design: A Systematic Review of published series of patients with adolescent idiopathic scoliosis treated with anterior thoracoscopic instrumentation.

Objective: To conduct a systematic review of the results of thoracoscopic surgery and to compare them with those of open anterior and posterior spine instrumentation to enable surgeons judge the applicability of the method.

Summary Of Background Data: Instrumentation through video-assisted thoracoscopic surgery is an attractive alternative for the treatment of thoracic adolescent idiopathic scoliosis.

Adolescent idiopathic scoliosis.

Conservative treatment with a brace continues to remain controversial. A recent study on the efficacy of brace treatment by the Scoliosis Research Society Study Group found it to be efficient, however, and recommends it. Surgical treatment of adolescent idiopathic scoliosis must be tailored to each individual need, type of curve, and surgeon's expertise.

Adolescent idiopathic scoliosis: Lenke type I-VI case studies.

Brace treatment is effective for selected patients with AIS, but when patients mature or curves progress beyond 40 degrees , surgery may be discussed with the patient and family. The advent of third-generation spinal instrumentation with pedicle screw systems has made extraordinary corrections possible. These posterior corrections must be done cautiously, however.
