Among all the vertebral synostosis or fusion, fusion of thoracic vertebrae is documented as less frequently present in comparison to sacral, cervical and lumbar vertebrae. It has got value for physicians, surgeons, radiologists, orthopaedics, anaesthetists, rheumatologists, pathologists, paediatricians and for forensic medicine also. Total 45 vertebral columns containing 540 thoracic vertebrae of unknown age and sex were studied by macroscopic examination and by Digital Vernier calliper. We found 13.33% fused thoracic vertebrae out of which four sets were of two fused thoracic vertebrae (8.88%), one set of three (2.22%) and one set of four fused thoracic vertebrae (2.22%). Their features were studied macroscopically and discussed. The calcification of anterior longitudinal ligament was present in 3 sets of fused thoracic vertebrae. In one set of 2 fused atypical thoracic vertebrae T11-T12 the ossification was present on sides of the body of vertebrae. The length of calcification ranged between 38.68mm- 86.33mm. As fusion of thoracic vertebrae can lead to stenosis of intervertebral foramen causing root pain and can lead to other complications also, measurements in the form of maximum length and width in the middle of intervertebral foramen of fused thoracic vertebrae were taken. The possible causes for the fusion of thoracic vertebrae can be congenital vertebral malformation, DISH, or other rheumatological, degenerative diseases, or infective disease like TB. In present study, the result of the study and its possible clinical significance is discussed.
