  • Congenital Malformation of the Ribs

    twelfth rib pair.[rrnursingschool.biz] We are reporting a case of VATER associated with rib anomalies in various forms like bifid rib, ribbon rib and rudimentary rib.[ncbi.nlm.nih.gov] In another subject, ribs two, three, four, and five were absent. The twelfth rib is variable in length; it may be markedly reduced in size, or as long as 14 cm.[anatomyatlases.org]

  • Congenitally Short Costocoracoid Ligament

    In another subject, ribs two, three, four, and five were absent. The twelfth rib is variable in length; it may be markedly reduced in size, or as long as 14 cm.[anatomyatlases.org] Various stages in evolution range from a complete C7 rib to a rudimentary form associated with fibrocartilaginous band.[slideshare.net] Wakeley.

  • Congenital Bilateral Absence of Vas Deferens

    In another subject, ribs two, three, four, and five were absent. The twelfth rib is variable in length; it may be markedly reduced in size, or as long as 14 cm.[anatomyatlases.org] Wakeley. (1931-32) Cervical ribs and rudimentary first thoracic ribs considered from clinical and etiological standpoints. J. Anat. 66:334-370.[anatomyatlases.org] The twelfth rib may be absent on one side and shortened on the other side. Asymmetric ribs are common. A bicipital rib is seen in relation to the first thoracic rib.[anatomyatlases.org]

  • Thoracic Outlet Syndrome

    Cervical radiographs showed long transverse process of C7 on the right side and a small rudimentary rib articulating with C7 on the left side.[ncbi.nlm.nih.gov] This rudimentary rib causes fibrous changes around the brachial plexus nerves, inducing compression and causing the symptoms and signs of TOS.[en.wikipedia.org] To prevent recurrence, patients must undergo first rib resection and anterior scalenectomy, as well as resection of any rudimentary or cervical ribs.[ncbi.nlm.nih.gov]

  • Spinal Trauma

    A small rudimentary rib may give rise to more symptoms than a well-developed rib because of a fibrous band attached between the cervical rib and sternum or 1st thoracic rib[chiro.org] The bone(s) may vary from a small nubbin to a fully developed rib.[chiro.org]

  • Thoracic Duct Obstruction

    Cervical ribs and rudimentary first ribs occur in less than 0.5% of the population.[emedicine.medscape.com] Rudimentary ribs usually arise higher in the neck than normal first ribs and typically articulate with the second rib rather than with the sternum.[emedicine.medscape.com] A search for cervical, rudimentary, or broad first ribs should be done. These structures should be resected during surgical therapy.[emedicine.medscape.com]
