Study Design: A retrospective cohort study. Purpose: The aim of this study was to determine any correlations between spinopelvic configuration and progressive collapse following acute osteoporotic compression spine fractures. Overview of Literature: Few studies have investigated the risk factors for progressive osteoporotic compression spine fractures. However, the correlation between the spinopelvic configuration, which is a crucial to optimize the management of lumbar degenerative diseases, and progressive collapse following acute osteoporotic compression spine fractures was not analyzed. Methods: We retrospectively identified all patients treated for thoracolumbar fractures in Assaf Harofe Medical Center between January 2008 and July 2013. Pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT) were measured for the pelvic parameters. For each patient, we classified the fracture according to the AOSpine Thoracolumbar Spine Injury Classification System. Height loss was measured initially and at a minimum of 3-month follow-up. The difference between initial and final height loss was documented as height loss difference. Results: The study included 124 patients comprised 86 women and 38 men. The mean patient age was 69±9.6 years. The mean length of follow-up was 14±15 months. No significant effect of the PI, PT, and SS angles on the vertebral fracture level (p >0.05) was found. Similarly, no significant relationship between the PI, PT, and SS angle and the fracture type according to the AO classification (p >0.05) was found. There was no correlation between PI, PT, and SS angles and initial height loss, final height loss and height loss difference (p> 0.05) Conclusions: The spinopelvic configuration represented by the PI, PT, and SS angle does not influence progressive collapse following acute osteoporotic compression spine fractures.

Study Design. Retrospective analysis. Objective. To demonstrate the effectiveness of hook-rod constructs in closing thoracic osteotomies safely and effectively. Summary of Background Data. The outcomes of hook-rod instrumentation in osteotomies for the correction of kyphosis at the lumbar region of the spine have been described. Little literature exists on the outcomes at the thoracic level. Methods. The radiographs and clinical scores of 38 patients who underwent pedicle subtraction osteotomy or Smith-Petersen osteotomy in the thoracic spine with the osteotomies closed using a central rod were retrospectively reviewed. Measurements included osteotomy angle, thoracic kyphosis (T2-T12), and maximum kyphosis. Perioperative and long-term complications were reviewed. Results. Thirty-eight patients underwent thoracic level osteotomies. There were 8 males and 30 females with a mean age of 51.9 years (range, 18-76 yr) at the time of surgery. The mean construct length was 13.2 levels (4-25). Kyphosis correction was equal in the 2 groups. In the pedicle subtraction osteotomy group, a mean of 24.7° (4°-47°) correction was obtained through the osteotomies compared with 24.0° (9°-65°) in the Smith-Petersen osteotomy group. Correction per osteotomy was 23.7° (4°-47°) in the pedicle subtraction osteotomy group compared with 11.8° (2.8°-46.0°) in the Smith-Petersen osteotomy group. No difference in the amount of correction achieved at the different regions of the thoracic spine was observed with either type of osteotomy with central rod closure. Conclusion. Central hook-rod constructs provide a safe and effective means of closing thoracic osteotomies and result in good correction of rigid sagittal plane deformities. [ABSTRACT FROM AUTHOR]

Vertebral osteoporotic fractures (VOF) are among the most frequent fractures in the elderly, often leading to an impaired lifestyle and a high economic burden. Although a reduced bone mass density is considered one of the main risk factors for VOF, its role in determining the fracture type, using the AO spine-DGOU classification for osteoporotic thoracolumbar fractures, as well as its progression, is unknown. The current study aimed to: (1) reveal whether the bone density of the vertebral bodies of fractured and non-fractured vertebrae predicts the type of fracture, (2) examine whether bone density is associated with the initial and progressive collapse of the vertebral body, and (3) provide predictive measures for fracture progression. The study sample included 124 patients (40 males and 84 females) with an acute osteoporotic vertebral fracture who underwent a computerized tomography scan at the time of diagnosis and an x-ray at least 3 months later. The bone density of the fractured and adjacent (non-fractured) vertebrae was measured at diagnosis. The magnitude of the collapse and the progression of the fracture over time were calculated from height measurements of the vertebral bodies at diagnosis and follow-up. Age was a significant factor in predicting the fracture type and magnitude of collapse, whereas sex and bone density were not. The severity of the fracture was involved in predicting its progression, demonstrating that severe-type fractures tended to continue to collapse after diagnosis. However, when each type was examined independently, the density of the fractured vertebra had a protective effect on fracture progression. To conclude, identifying the type of fracture is beneficial in determining patient prognosis. Furthermore, the density of the fractured vertebra, the magnitude of collapse, and patient age are valuable predictors of fracture progression., (© 2024 The Author(s).
