Abstract: Introduction: Adolescent Idiopathic Scoliosis (AIS) is most common type of scolisis which is affecting girls more than boys. Affecting children between age 10 to18. AIS curves progress during radip growth period of child. Locate usually at thoracic level and involves right convex curve. Due to cosmetic reasons, pain and in some cases due to neurological involvement such cases needs operative involvement. In this study involves 20 such patients operated with posterior spinal approach and fixation for the same and followed up for one months for radiographic and clinical outcomes.
Materials and Methods: 20 patients out of which 5 male and 15 female with AIS were managed with posterior spinal pedicle screws instrumentations and follow-up with various criteria regarding its outcomes such as postoperative pain relief, cobb’s angle, average screws insertion, average level of fixation, mean duration of surgery, blood loss, and post operative complications such as neurological deficit, infection or implant failure.
Results: In this study which was done on 20 patient. Most common type of lenke’s curve is Type-1. Average Pre operative VAS score was 8.5 that Reduced to 1.9 Post operative. Average Pre operative cobb’s angle in all patients were 57.15 which is average 11.65 post operative, after 1 year of follow-up average cobb’s angle were 17.2 degrees. So average loss in correction after 1 year is 5.55. Average screw needed in this fixation is 15.6. Range minimum of 12 to maximum 19 screws required in fixation. In all 20 patients average 1.35 screws were fixed per level vertebrae. So basically, it is low density pedicle screw fixation. Average duration of surgery time is mean 6 hours 25 minutes. Range from minimum of 5 hours to max 9 hours. Mean age was 16.1. Mean blood loss was 773.5 mL. one patient developed post operative neurological deficit which progressively recovered within six months, no other significant complication in any patient was observed.
Conclusion: Based upon the results obtained from this review of 20 patients of AIS with minimum one year of follow-up we suggest that the all-screw method is efficient and safe.
The outcomes in three-dimensional correction are satisfactory and comparable.
The curve maintenance is good with minimal loss of correction. Compared with age-matched healthy populations, these patients did present some limitations on their physical health, as assessed by the SRS-30 questionnaire.
