Concomitant low-grade isthmic L5-spondylolisthesis does not affect the course of adolescent idiopathic scoliosis.

Background: Scoliosis with spondylolisthesis was described in 4.4-48%. No information on clinical impact or outcome is available.

Results of brace treatment of adolescent idiopathic scoliosis in boys compared with girls: a retrospective study of 102 patients treated with the Boston brace.

The aim of the study was to compare the results of brace treatment of adolescent idiopathic scoliosis (AIS) in male patients with matched female patients and to assess the effectiveness of bracing of boys in AIS and to discuss the results with published data. Between 1987 and 1995, 51 consecutive male patients with AIS were treated with the Boston brace. The patients were advised to wear the brace 23 h/day.

Effect of growth velocity on the progression of adolescent idiopathic scoliosis in boys.

Growth velocities, curve magnitudes, curve patterns and Risser signs of 80 consecutive untreated boys with adolescent idiopathic scoliosis were studied retrospectively and compared with the progression velocity of the curves. Growth velocity >or=4 cm/year with curves >or=25 degrees increased progression velocity of curves significantly (P<0.001).

Effectiveness of the Providence nighttime bracing in adolescent idiopathic scoliosis: a comparative study of 36 female patients.

The aim of the study was to assess the results of treatment of adolescent idiopathic scoliosis (AIS) with the Providence nighttime brace at 1.8 years after discontinuation of bracing. A total of 36 consecutive female patients with an average Cobb angle of 28.

Growth and progression of adolescent idiopathic scoliosis in girls.

The progression velocity of scoliosis was studied for 535 consecutive girls with untreated adolescent idiopathic scoliosis. At the first visit the mean age of the patients was 13.9 years (range 9-19 years), the mean magnitude of the major curves was 23.

Does gender affect outcome of surgery in adolescent idiopathic scoliosis?

Study Design: A retrospective follow-up study comparing 2 matched groups.

Objective: To compare long-term results of operative treatment of adolescent idiopathic scoliosis (AIS) between males and females matched for age, curve magnitude and type, and the instrumentation used.

Summary Of Background Data: It has been suggested that in AIS, the spine is more rigid in males than in females, because brace treatment fails to halt progression of the curves in males.

Cotrel-Dubousset (CD) or Universal Spine System (USS) instrumentation in adolescent idiopathic scoliosis (AIS): comparison of midterm clinical, functional, and radiologic outcomes.

Study Design: A retrospective comparison of the clinical, radiologic, and functional results of Cotrell-Dubousset (CD) and Universal Spine System (USS) instrumentation for adolescent idiopathic scoliosis (AIS).

Objectives: To establish whether there are any differences in outcome between the 2 instrumentation systems.

Summary Of Background Data: CD is the first complex posterior double rod instrumentation system to provide multiple hook fixation.

Harrington and Cotrel-Dubousset instrumentation in adolescent idiopathic scoliosis. Long-term functional and radiographic outcomes.

Background: Previous studies have shown that the long-term clinical outcome does not correlate with the radiographic outcome in patients treated with Harrington instrumentation for adolescent idiopathic scoliosis. Cotrel-Dubousset instrumentation has been reported to provide better correction radiographically, but it is unclear whether it provides better long-term clinical or functional outcomes. We are not aware of any long-term studies comparing Harrington and Cotrel-Dubousset instrumentation.

Height of girls with adolescent idiopathic scoliosis.

In a Finnish population, the standing height of 1500 consecutive female patients aged 9-24 years (mean 13.9 years) with untreated idiopathic scoliosis of at least 10 degrees in their lateral curves was compared with the standing height of average girls. The mean magnitude of the major curves was 29.

Comparison of long-term functional and radiologic outcomes after Harrington instrumentation and spondylodesis in adolescent idiopathic scoliosis: a review of 78 patients.

Study Design: A retrospective follow-up study of adolescent idiopathic scoliosis after Harrington instrumentation and spondylodesis was conducted.

Objective: To correlate radiographic parameters with the Scoliosis Research Society questionnaire in terms of patient outcome, clinical findings, spine mobility, and trunk strength measurements.

Summary Of Background Data: Previous studies have shown that long-term radiologic correction can be achieved with Harrington instrumentation.
