Introduction: Lumbosacral Transitional vertebrae are congenital anomalies of lumbosacral vertebral junction. It may present either as sacralization of fifth lumbar vertebrae or lumbarization of first sacral vertebrae. Various secondary pathological spinal conditions such as intervertebral disc herniation and/or degeneration, facet joint arthrosis and spinal canal or foraminal stenosis are associated with the presence of LSTV. The failure in the identification may lead to clinical consequences such as errors in diagnosis of disease and lumbosacral procedures. Objective: The aim of this study was to determine the prevalence and patterns of LSTV in patients presenting to Department of Radiology of Nobel Medical College Teaching Hospital, Nepal.. Methodology: A descriptive cross-sectional study was conducted in Department of Radiology of Nobel Medical College Teaching Hospital, Nepal.Plain radiographs including Antero-posterior (AP) and Lateral views of lumbosacral spine of 343 patients referred for the scan were analyzed for the presence of lumbosacral vertebrae. Result: Out of 343 patients, LSTV was found in 61 (17.8%) subjects. Thirty-eight subjects (11.1%) exhibited sacralization and 23 (6.7%) showed lumbarization.Out of total LSTV subjects, type I A was present in 8 (13.1%), type I B in 21 (34.4%), type II A in 10 (16.4%), type II B in 5 (8.2%) , type III A in 6 (9.8%) , type III B in 9 (14.8%) and type IV in 2 (3.3%). Conclusion: The LSTV is prevalent in almostone-fifth of subjects presenting to department of radiology of Nobel Medical College and Teaching Hospital, Biratnagar for lumbosacral scan.. Sacralization occurs more frequently than lumbarization, both of which alter the morphology of anatomical structures in spine. The presence of anomaly in this region may be related to occurrence of various pathological and clinical conditions.

“…Sacralization was more common than lumbarization, similar to other studies. 1,6,9 A study conducted in Australia reported lumbarization to be more common than sacralization, in contrast to our study, which could be because of the exclusion of type I LSTV in his study causing decreased recorded cases of sacralization. 8 LSTV was more common in females in our study which was similar to other studies conducted in a similar setting in Nepal.…”

“…The prevalence rate reported in our study was 9.48%, which was lower compared to similar studies conducted in Nepal. 1,6 However, in an MRI-based study, 7 the LSTV prevalence was 3.8%, much lower as compared to our study. Similarly, other similar studies from India and Saudi Arabia had lower prevalence as compared to this study.…”

Lumbosacral Transitional Vertebra among Patients Visiting the Department of Orthopaedics in a Tertiary Care Centre: A Descriptive Cross-sectional Study

Introduction: Lumbosacral transitional vertebra is a normal anatomical variant at the L5-S1 junction with an incidence as high as 4-36%. This alteration results in incorrect identification of vertebral segments leading to wrong surgery. The aim of the study was to find out the prevalence of lumbosacral transitional vertebra among patients visiting the department of orthopaedics in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted from 11 September 2021 to 31 May 2022, after receiving ethical clearance from the Institutional Review Committee (Reference number: IRC-2021-9-10-09). The patients with plain radiographs of the lumbosacral spine (anteroposterior view) were assessed and evaluated by a fellow and consultant of the orthopaedic spine and classified as per Castellvi's radiographic classification. Convenience sampling was done. Point estimate and 95% Confidence Interval were calculated. Results: Among 1002 patients, lumbosacral transitional vertebra was detected in 95 (9.48%) patients (9.40-9.56, 95% Confidence Interval). Out of 95 (9.48%), patients with the lumbosacral transitional vertebra, 67 (70.53%) had sacralisation and 28 (29.47%) had lumbarization. The mean age of the patients at the time of the study included in the study was 41.6±15.12 years (range 18-85 years). The lumbosacral transitional vertebra was more common in females than males. According to the Castellvi classification, type IIa was the most common type 47 (49.47%). Conclusions: The prevalence of lumbosacral transitional vertebra was similar to other studies done in similar settings.

Introduction: The sacrum is considered as a highly variable bone. Several morphological variations have been documented which exhibit differences in the frequency of occurrence and morphological characteristics in various study populations. Variant anatomy of the sacrum may be associated with backache, enuresis, neurological anomalies of the lower limb and functional disorders of lower urinary tract. Purpose: The purpose of this study was to identify and describe morphological variations of sacrum in Indian population and enable comparison with different populations. Materials and Methods: The study was conducted on 108 dry adult human sacra and morphological characteristics and variations were noted. Results: Sacral skewness was observed in 7.4% sacra with right sided skewness being predominant. The presence of accessory auricular surface (AAS) was noted in 13% sacra which was at the level of S3 vertebra in most sacra. Spina bifida (SB) was observed in 11.1% sacra and it was most commonly located at S1 vertebral level. Furthermore, the lumbo-sacral transitional vertebra (TV) was documented in 10.2% sacra. Conclusions: Sacrum displays numerous variations in Indian population such as skewness, AAS, SB and TV. Thorough knowledge of morphological characteristics and variations of sacrum is vital and should be contemplated during diagnosis and treatment of sacrum-related diseases. KEY WORDS: Accessory auricular surface, Spina bifida, Transitional vertebra, Sacral skewness, Variations.
