We investigated, using several noninvasive imaging techniques, the thoracolumbar spine of a total of 44 adult rhesus macaques of both genders. Radiographic examination of the vertebral column showed a predominant spine phenotype with 12 rib\u2010bearing thoracic vertebrae and 7 lumbar vertebrae without ribs in 82% of subjects, whereas a subset of subjects demonstrated 13 rib\u2010bearing thoracic vertebrae and 6 lumbar vertebrae without ribs. Computer tomography studies of the thoraco\u2010lumbar spine in two cases with a pair of supernumerary ribs showed facet joints between the most caudal pair of ribs and the associated vertebra, supporting a thoracic phenotype. Magnetic resonance imaging (MRI) studies were used to determine the relationship between the lumbosacral spinal cord and the vertebral column. The length of the conus medullaris portion of the spinal cord was 1.5\u2009\u00b1\u20090.3 vertebral units, and its rostral and caudal positions in the spinal canal were at 2.0\u2009\u00b1\u20090.3 and 3.6\u2009\u00b1\u20090.4 vertebral units below the thoracolumbar junction, respectively (<jats:italic>n<\/jats:italic>\u2009=\u200944). The presence of a set of supernumerary ribs did not affect the length or craniocaudal position of the conus medullaris, and subjects with13 rib\u2010bearing vertebrae may from a functional or spine surgical perspective be considered as exhibiting12 thoracic vertebrae and an L1 vertebra with ribs.
