“…In cases where the cranial limit of Hoxa10 gene expression was displaced by one or two segments in the caudal direction, the first lumbar vertebra (L1) displayed phenotypic characteristics of thoracic vertebrae such as the persistence of costal processes, which later form lumbar ribs [29]. This is accompanied, in some cases, by lumbarization of the first sacral segment as depicted in the current study [1112]. Ectopic expression of Hox-c6 gene and mutations of the FYVE, RhoGEF, and PH domain-containing protein 1 ( FDG1 ) gene or errors in its signaling pathway have also been implicated in lumbar rib development [9].…”

Supernumerary lumbar ribs: a rare occurrence on an adult African male skeleton

Supernumerary lumbar ribs are usually asymptomatic and discovered incidentally during routine diagnostic radiography. During a routine inventory of the research skeletal repository at the University of the Witwatersrand, a rare case of bilateral supernumerary ribs on the first lumbar vertebra was observed. The skeletal specimen belonged to a 70-year-old African male whose recorded cause of death was esophageal carcinoma. Plain radiography revealed bilateral joint cavities between the transverse processes of the first lumbar vertebra and the supernumerary ribs. Clinically, supernumerary lumbar ribs may present with pain of the renal angle, cause confusion during enumeration of the vertebral levels on radiographs, and may be misinterpreted as fractures, kissing osteophytes, and/or calcification of abdominal vasculature.

“…The sacralisation can also be attributed to the dependency of the sacral morphology to the load related fusion of the bone structure as it helps in the transmission of weight to lower extremity 22 . Wellik and Capecchi 23 reported genetic factors implicated in the development of transitional vertebra when mutations in the Hox10 and Hox11 genes can alter the normal pattern of lumbar and sacral vertebra leading to lumbosacral transition vertebrae.…”

“…Also, fourth sacral nerve roots may possibly be seen exiting through the sacral hiatus along with the fifth sacral, coccygeal roots and the filum terminale in sacra with lumbarisation. Any sacrococcygeal tumor, if occurs in individuals with lumbarised sacra, may compress upon fourth sacral roots simultaneously and present with unusual clinical findings due to neurological involvement of the bladder and rectum also [38]. assimilated into sacrum but not as developed as first sacral vertebra.…”

Context: Lumbosacral transitional vertebrae (LSTV) are congenital anomalies that occur due to defect in normal segmentation of the lumbosacral spine during development. This may be either in the form of assimilation of fifth lumbar vertebra with the sacrum (sacralisation), or transition of the first piece of sacral vertebra into the lumbar configuration (lumbarisation). Aims and Objectives:Although presence of LSTV is common in general population but knowledge about its exact clinical implications is still lacking. The primary aim of the present study was to determine the rate of incidence of transitional vertebra and their sex difference (if present) in dried human sacra. Secondary aim was to study these transitional vertebra in detail and correlate these findings clinically. Materials and Methods:A total of fifty unbroken adult sacra were examined (male to female ratio of 3:2). The presence or absence of a lumbar transitional vertebra was noted and classified as incomplete or complete. The sacral indices (SI) of all sacra were measured and values compared between typical and atypical sacra with LSTV as well as between male and female sacra.Results: Out of fifty sacra, six sacra (12%) showed presence of LSTV. Among them, four (8%) showed sacralisation of the fifth lumbar vertebra and two (4%) showed lumbarisation of first sacral vertebra. Among the four sacra showing sacralisation, two showed incomplete fusion and two showed complete fusion of fifth lumber vertebra with sacrum. LSTV was found to be more common in male than female. Sacralisation was seen only in male sacra while lumbarisation only in female sacra. The difference in the mean SI of typical sacra (97.76±4.08) and sacra with LSTV (83.69±2.38 and 98.11±1.52 for sacralised and lumbarised sacra respectively) was found to be statistically significant (p<0.05) and that between the male (94.55±5.70) and female (100.14±3.42) sacra was found to be highly significant (p<0.01). Conclusion:Presence of LSTV has many clinical and forensic implications and its knowledge is important for orthopaedic surgeons, neurosurgeons, forensic experts and also to radiologists.
