Objective: The Quality of Life Profile for spinal deformities (QLPSD) was developed to evaluate the quality of life of patients with scoliosis and other spinal deformities. The purpose of the study was to systematically translate the QLPSD into Turkish and examine the reliability and validity of the Turkish version. Methods: This methodological study was conducted with 125 participants with idiopathic scoliosis. After the translation of the QLPSD into Turkish systematically, all participants answered the Turkish version of the QLPSD (T-QLPSD) and Scoliosis Research Society—22 items (SRS-22) questionnaires. Intraclass correlation coefficient (ICC) and Cronbach’s α statistics were used to test the reliability of the tools: convergent and construct validity of the tools was assessed using exploratory factor analysis and Pearson’s correlation analysis. Results: One hundred twenty-five participants were included in the study. The mean age of them was 13.7 ± 2.2 years. For the T-QLPSD total score, Cronbach’s α was 0.91, and the ICC was 0.94. A very good correlation was found between T-QLPSD and SRS-22 total scores (r = −0.71). Participants with mild scoliosis reported less back pain (P = .038), better back flexibility (P=.001), and body image (P=.044) compared to moderate scoliosis. Conclusion: The T-QLPSD was found to be a reliable and valid scale for assessing quality of life in idiopathic scoliotic patients in Türkiye. Level of Evidence: Level II, Diagnostic Study.

Objective: This study aimed to examine the relationship between lumbosacral transitional vertebra (LSTV), classified by Castellvi’s system, and lumbar disc degeneration, graded using Pfirrmann’s classification, based on radiological assessment. Methods: This retrospective study analyzed 2516 patients (1548 females and 968 males) with a mean age of 51.83 ± 15.6 years withchronic low back pain who underwent lumbosacral magnetic resonance imaging and computed tomography scans at a single centerbetween January 2018 and January 2021. Pfirrmann grading was used to assess L4-L5 intervertebral disc degeneration, and Castellviclassification determined the anatomical type of LSTV. Correlation analysis was performed to evaluate the association between LSTVpresence and disc degeneration. Additionally, a proportional-odds ordinal logistic regression model was used to examine the relationship between Pfirrmann grade and patient-specific factors (age, gender, and LSTV presence). Results: According to Pfirrmann classification, 113 patients were grade I, 402 were grade II, 877 were grade III, 861 were grade IV, and 263 were grade V. A total of 771 patients (30.6%) did not have LSTV, while the remaining 1745 patients (69.4%) had LSTV. A statistically significant association was found between LSTV presence and Pfirrmann grade (P < .001, r=.200). Patients with LSTV had 0.75 times higher probability (95% CI: 0.58–0.90, P < .001) of exhibiting a higher Pfirrmann grade compared to those without LSTV. However, no significant correlation was observed between LSTV subtypes classified by Castellvi and Pfirrmann grade (P=.379). Additionally, age was significantly correlated with Pfirrmann classification, LSTV presence, and Castellvi classification (P < .001). Female patients had 1.34 times higher likelihood (95% CI: 1.19–1.49, P < .001) of exhibiting a higher Pfirrmann grade compared to male patients. Conclusions: This study highlights the significant association between LSTV and advanced disc degeneration, establishing LSTV as apotential risk factor for progressive spinal changes. It emphasizes the importance of early detection and targeted management, particularly for older adults and females who are more susceptible to severe degenerative changes.
