Abstract

Background: Scoliosis is a complex three-dimensional deformity of the spine that
involves the coronal, sagittal, and axial planes with fixed rotation of vertebrae.
Adolescent idiopathic scoliosis is the most common type of scoliosis accounting for
about 80% of idiopathic scoliosis involving healthy individuals. Aim: To assess the
functional outcome of the patient treated surgically with a Scoliosis Research Society
questionnaire administered to the patient pre operatively and post operatively.
Materials and Methods: Study Design: A prospective observational study. Study area:
Out-Patient and In-Patient wing of the Department of Orthopaedics in Malabar
Institute of Medical Sciences Hospital, Calicut. Study Period: The study was conducted
from June 2017 to May 2018 for a period of 1 year. Study population: Patients coming
to the outpatient wing and patients admitted in the inpatient wing of Department of
Orthopaedics in Malabar Institute of Medical Sciences Hospital, Calicut. Sample size:
25. Sampling method: Simple Random sampling method. Inclusion Criteria: All
patients diagnosed with adolescent idiopathic scoliosis and who are treated by any
method of surgical correction. Study tools and Data collection procedure: SRS
questionnaire will assess the patient in five different domains of functional outcome
namely pain, mental status, function, self-image and satisfaction with treatment. The
mean scores obtained in these five domains and total score are statistically analyzed to
find any significant difference preoperatively and post operatively. An improvement in
the total SRS score by 0.4 at the latest assessment is considered as Minimum Clinically
Important Difference (MCID). Statistical Methods: Data will be analyzed using SPSS V
21.0 (IBM SPSS Inc. Chicago, IL). Continuous data will be summarized as Mean with
SD or Median with Inter Quartile range. Categorical data will be summarized as
frequency with percentage. Categorized data will be analyzed using Chi-Square test,
Fischer’s exact test or McNemar test. Paired T test will be used for preoperative and
post-operative changes.
