Lyon bracing in adolescent females with XXXX : a prospective study based on @entity1635 and SOSORT criteria.

BACKGROUND: The Lyon brace is commonly prescribed in many European countries to @entity1 with thoracic curves and is based on the three-point pressure system. The purpose of this study was to evaluate the efficacy of Lyon bracing for the conservative treatment of adolescent females with @entity1514 in a case series selected on the basis of the @entity1635 ( @entity1635 ) Committee on Bracing and Nonoperative Management Standardization Criteria and followed the guidelines on management of @entity2112 with corrective braces, proposed by the International Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT). METHODS: Prospective study based on an ongoing database. From 1297 @entity1 treated for @entity2112 between 1995 and 2014 fulfill the inclusion criteria 102 @entity1 treated with Lyon brace. Of these, 69 @entity1 had a definite outcome, 17 have abandoned treatment e 16 are still in treatment. The 104 @entity1 were adolescent females with curvatures in the thoracic spine and a pre-treatment Risser score ranging from 0 to 2. All @entity1 were prescribed with full-time Lyon bracing. The minimum duration of follow-up was 24  months after the end of weaning (mean: 41.64        31.45  months). Anteroposterior radiographs were used to estimate the curve magnitude (CM) at 5 time points: beginning of treatment (t1), one year after the beginning of treatment (t2), intermediate time between t1 and t4 (t3), end of weaning (t4), 2-year minimum follow-up from t4 (t5). Three outcomes were distinguished: curve correction, curve stabilization and curve progression. RESULTS: The results from our study showed that of the 69 @entity1 with a definite outcome the CM mean value was 31.51          4.34 SD at @entity8034          7.6 SD at t5. Curve correction was accomplished in 85.5  % of @entity1 , curve stabilization was obtained in 13  % of @entity1 and curve progression was evident in only 1.5  %. None of the @entity1 were recommended surgery post-bracing. Of 17 @entity1 who abandoned the treatment, at the time of abandonment (14.4 age) have achieved curve correction in 13 cases (77  %), stabilization in 53 cases (18  %) and progression in 1 case (5  %). CONCLUSION: The Lyon brace, through its biomechanical action on vertebral modeling, is highly effective in correcting thoracic curves in particularly when the SOSORT guidelines were adopted in addition to the @entity1635 criteria.
