Purpose. The aim of this study is to determine the prevalence of lumbosacral transitional vertebra (LSTV) in a well-represented general population. Methods. For a retrospective cohort study, abdominal radiographs of adult subjects were queried with clear visibility of the vertebral body articulation of the last rib, all lumbar transverse processes, and complete sacral wings. Exclusion criteria included any radiologic evidence of previous lumbosacral surgery that would block our view. A total of 6200 abdominal films were reviewed, and 3607 were identified as being suitable for the measurement of the desired parameters. Results. A total of 3607 subjects were identified as eligible for the study, and 683 (18.9%) were classified as positive for a lumbosacral transitional vertebra. The prevalence of sacralization and lumbarization was found as 17.2% and 1.7%, respectively. The average age at the time of the study was 39.5 ± 15.2 years (18–86 years). Conclusions. As a result of different opinions, LSTV retains its controversial status. Our prevalence study of the general population will provide assistance for resolution of the controversy. Prevalence studies of the general population with a wide participation will shed light on comparative studies.

Objectives: The aim of this study was to evaluate the results of reamed and locked intramedullary nailing for tibial diaphysis fractures. Materials and methods: The study included 38 patients (26 males, 12 females) who were treated with reamed and locked intramedullary nailing for tibial diaphysis fractures. Fractures were classified according to Gustilo-Anderson classification and functional results were assessed using the Johner-Wrush criteria. Results: The mean age was 36 years (range 18-61). There were 21 AO/ASIF type A, 16 type B, and 1 type C fractures. Twenty-four fracture were closed (63.1%) and 14 (36.9%) were open fractures. According to the Gustilo-Anderson classification, 9 were grade I, 4 patients grade II, and one grade IIIA open fractures. Intramedullary nailing was performed following open reduction in 18 patients, and closed reduction in 20. The mean time to surgery was 9.4 days and the mean follow-up was 29 months. Union was achieved in all patients within a mean of 17.6 weeks. Anterior knee pain developed in 18 patients and infection developed in three patients. Angular deformity less than 10º was developed 12 patients (31.6%). There were screw breakacge and synostosis in four and two patients respectively. According to the Johner-Wrush criteria, functional results were very good in 23 patients (60.5%), good in 12 patients (31.6%) and fair in 3 (7.9%) patients. Conclusion: Treatment of tibial diaphysis fractures with reamed and locked intramedullary nailing gives satisfactory results. It should be considered as first choice in the treatment of these fractures.
