COSMESIS GAIN FOLLOWING SCOLIOSIS SURGERY CORRELATING THE TYPE OF TREATMENT AND PATIENTS' PERCEPTION

Abstract

The Walter Reed Visual Assessment Scale (WRVAS) is a valid and reliable tool, designed to measure physical deformity as perceived by patients with idiopathic scoliosis. It is unclear whether the type of treatment in patients with thoracic adolescent idiopathic scoliosis affects the patients' perception of cosmesis gain. We studied 40 patients with Adolescent Idiopathic Scoliosis treated with posterior spinal fusion with (20) and without thoracoplasty (20) aiming to assess correlation of improvement in radiological parameters to subjective cosmesis gain.

Patients with Adolescent Idiopathic Scoliosis treated with posterior spinal fusion with thoracoplasty (20) and without thoracoplasty (20) filled out Walter Reed Visual Assessment Scale (WRVAS) forms with their perception of deformity before and after operation at the clinic follow-up. The WRVAS forms include seven aspects of the deformity i.e. spinal deformity, rib prominence, lumbar prominence, thoracic deformity, trunk imbalance, shoulder asymmetry and scapular asymmetry. Each aspect is shown with five figures of increasing severity of the deformity and scored from minimum (1) to maximum (5). Results are presented as the sum of the seven questions. The lowest possible score for the total is 7, while the highest possible total score is 35. The curve magnitude was divided into 5 subgroups as 30 and under, 30-40, 40-50, 50-60 and 70 and over.

Floor and ceiling effects were analysed as percentage of cases with minimum and maximum scores.

Our study confirmed that following posterior scoliosis surgery with and without thoracoplasty, there was significant improvement in perceived appearance. Overall spinal deformity and thoracic deformity correction were comparable in two groups. However, improvement in rib hump prominence, flank prominence, restoration of truncal, shoulder and scapular symmetry were much better rated by the patients with PSF and thoracoplasty group using Walter Reed Visual Assessment Scale.
