Calcium deposition and ossification may occur in soft tissue such as ligaments. Sometimes, an ossified ligament can cause various problems, including nerve compression and the resulting pain. In living individuals, these conditions can be diagnosed using ultrasonography and computed tomography (CT). However, the identification and description of ossified ligaments in skeletal specimens have received comparatively little attention. In paleoanthropology, the recognition of pathological changes in skeletal remains is particularly important.</span><br> <span style="line-height:150%"><b>Case presentation</b>: The current study presented an uncommon case involving ossification of the supraspinous ligament in a dry thoracic vertebra. This ossification resulted in the formation of a sharp, vertically oriented bony projection measuring 16 mm in length and forming an angle of 135&deg; with the axis of the spinous process.</span><br> <span style="line-height:150%"><span style="unicode-bidi:embed"><b><span lang="EN"><span style="line-height:150%">Conclusion:</span></span></b><span lang="EN"><span style="line-height:150%"> A precise understanding of anatomical variations and conditions such as ligament ossification is essential for surgeons.</span></span> <span style="line-height:150%">Furthermore, pathological evidence preserved in skeletal remains provides valuable insights into the health and living conditions of past populations.</span><span style="line-height:150%"><span style="font-family:&quot;Times New Roman&quot;,serif"></span></span></span></span></span></span></div> Supraspinous ligament, Ossification, Dry bone, Ossified ligament, Thoracic vertebra 0 0 http://anatomyjournal.ir/browse.php?a_code=A-10-111-4&slc_lang=en&sid=1 Samereh Dehghani-Soltani samereh.dehghani@gmail.com No Department of Anatomical Sciences, Faculty of Medicine, Rafsanjan University of Medical Sciences, Rafsanjan, Iran Ahmad Shabanizadeh shabani54@yahoo.com No Department of Anatomy, Faculty of Medicine, Immunology of Infectious Diseases Research Center, Research Institute of Basic Medical Sciences, Rafsanjan University of Medical Sciences, Rafsanjan, Iran Abdolreza Babaee babaee.ab@gmail.com Yes Department of Anatomical Sciences, Faculty of Medicine, Rafsanjan University of Medical Sciences, Rafsanjan, Iran.
