    Low back pain and posture
    (1999) Tüzün Ç.; Yorulmaz I.; Cindaş A.; Vatan S.
    This study was designed to analyse postural aberrations of the back and lower back region in patients with acute and chronic low back pain and to investigate the accordance of clinical and radiological assessments. Fifty patients with acute and 50 with chronic low back pain and 50 controls were studied and a detailed spinal physical examination was performed. In addition, the angles of thoracic kyphosis, lumbar lordosis and sacral inclination were assessed radiologically. Differences among the three groups, correlations of radiological parameters with each other and with clinical parameters such as age, gender and body mass index, and the accordance of clinical and radiological postural assessments were investigated. It was concluded that there were no statistically significant differences among the groups for angles of thoracic kyphosis, lumbar lordosis and sacral inclination; however, we found significant correlations among all radiological parameters, especially between lumbar lordosis and sacral inclination. Both lumbar lordosis and sacral inclination were increased with body mass index, and lumbar lordosis and thoracic kyphosis were increased with age. Clinical assessments of thoracic kyphosis and lumbar lordosis were not in accordance with radiological assessments.

    Does the Extent of Rod Bending and Actual Lumbar Lordosis Mismatch Affect Quality of Life?
    (Elsevier Inc., 2024) Bayatli E.; Dogan I.; Özgüral O.; Kuzukiran Y.C.; Demiryurek S.; Mete E.B.; Ozalp Ates F.S.; Zaimoğlu M.; Eroglu U.; Kahilogulları G.; Ugur H.C.; Attar A.; Caglar Y.S.
    Background: To evaluate any mismatch between rod bending and actual lordosis during posterior lumbar instrumentation and its effects on the quality of life (QOL) of patients. Methods: Patient records for posterior lumbar fusion in 2018–2023 were retrospectively reviewed. The radiologic parameters consisted of pelvic incidence, sacral slope, L1S1 lumbar lordosis, lumbosacral angle, the distance between the posterior wall of the vertebra and the rod, lordosis of the rod. The postoperative QOL of patients was assessed using Oswestry Disability Index. The patients were grouped postoperative into Group-1 (minimal/moderate disability) and Group-2 (severe disability/crippled/bed bound). Results: Total of 133 patients were included; 99 women, 34 men. The difference was significant for patients with diabetes to be presented in the more disabled Group-2. The distance between the posterior vertebral wall and the rod was found to be short in Group-2. Preoperative and postoperative sagittal lumbar Cobb angles were significantly higher in Group-2. The changing degree of pain was found to score high in Group-2. The postoperative visual analog scale was high in Group-2. The difference between the preoperative and postoperative lumbar sagittal Cobb and rod Cobb-angles was found to be high in Group-2. Conclusions: The results of our study confirm the importance of considering the preoperative actual lumbar lordosis during bending and maintaining it as much as possible. To our knowledge, this is the first study that evaluated the effect of rod bending on quality of life (QOL) and supports that this might be affected in case of any mismatches. © 2023 Elsevier Inc.
