Impact of Scoliosis Severity on Functional Capacity in Patients With Adolescent Idiopathic Scoliosis

Purpose: The aim of this study is to evaluate the walked distance and physiological responses during incremental shuttle walk test in patients with different degrees of adolescent idiopathic scoliosis (AIS). Methods: We evaluated 20 healthy teenagers and 46 patients with AISthey were divided into 2 groups: AIS > 45 degrees and AIS 45 degrees presented significant reduced incremental shuttle walked distance compared with the AIS < 45 degrees and control group [447 (85), 487 (95), and 603 (85), respectively]. Patients with AIS also showed reduced forced vital capacity (P = .001) and expiratory volume in the first second (P = .005) compared with control group. Moderate correlations between forced vital capacity (r = -.506) and tidal volume (r = -.476) with scoliosis angles were found. Conclusions: The incremental shuttle walk test was capable of identifying reduced functional capacity in patients with different degrees of AIS. Moreover, the severity of spinal curvature may exert influence on ventilatory and metabolic variables.Fed Univ Sao Paulo UNIFESP, Dept Human Movement Sci, Lab Epidemiol & Human Movement, Santos, SP, BrazilAlbert Einstein Hosp, Dept Orthoped, Sao Paulo, SP, BrazilFed Univ Sao Paulo UNIFESP, Dept Human Movement Sci, Lab Epidemiol & Human Movement, Santos, SP, BrazilWeb of Scienc

Radiographic and functional evaluation of the iliac bone graft in the treatment of adolescent idiopathic scoliosis

This study aimed to assess the impact of the use of an additional iliac bone graft on functional and radiographic results after thoracic spine arthrodesis with pedicle screws in patients with adolescent idiopathic scoliosis. Participants were divided into two groups: a control group that received only local bone (n = 19) and a second group that, in addition to this procedure, received an iliac graft (n = 22). the evaluations were performed on preoperative, immediate postoperative, and last follow-up (mean 29.7 months; minimum 12 months). Radiographic evaluations included the loss of correction and the presence of nonunion. the functional outcome was evaluated using the Scoliosis Research Society-30 questionnaire. Surgical complications and the presence of iliac donor site pain were also described. There were no significant differences between groups in the pseudoarthrosis rate, loss of correction over time, and quality of life. We concluded that the addition of bone graft from the iliac yielded no benefit in terms of the fusion rate and functional outcomes. the appropriate facetectomy, bed preparation, and filling with a local bone graft must be adequate to achieve an adequate fusion on surgical treatment of adolescent idiopathic scoliosis.
