Objective: In this study, Scheuermann’s kyphosis patients with 80° or more kyphotic deformities were evaluated both for correcting the deformity and effects of changes in the life qualities. Materials and Methods: Mean age was found to be 18.6±2.4 years and patients with minimum 2 years follow-up were evaluated. In 10 patients below 17 years of age (27%), segmental compression was applied through the apex and correction was obtained. In the remaining 27 patients (73%) correction was obtained with Ponte osteotomies performed at the apex of the kyphosis and the same fixation and maneuver as the first group. Patients thoracic kyphosis angles if concomitant scoliosis was present scoliosis angles were measured via the Cobb method preoperatively, postoperatively and during the last control visit. Patients were evaluated preoperatively with SRS-22 questionnaire. Mean values of the preoperative, postoperative and in the last control visit were compared statistically (p=0.05). Results: Preoperative mean kyphotic angles were measured as 84.9°±5.0°. Postoperative mean kyphotic correction angles were measured as 40.7°±6.5° and in all patients’ physiological kyphotic angles were obtained (p=0.0001). Preoperative SRS22 questionnaire mean score was 3.17±0.3 while postoperatively increased to 4.95±0.1 which was found to be statistically significant (p=0.0001). Almost all patients were satisfied with the pain improvement, look, function, mental status and satisfaction from the treatment was measured as 4.5 to 5 that is almost perfect. Kyphotic correction angles were found to be statistically similar between patients under and over 18 years of ages (>0.05). Conclusion: As a result, SRS-22 scores which was used for the first time in Scheuermann’s Kyphosis patients undergone surgery, a statistically meaningful result was obtained in quality of life scores and relief of mechanical pain.
