whether there is a tuft of hair in the dimple; whether there are potentially related problems such as weak lower limbs; the distance from the buttocks to the dimple (closer is better). For clinicians dealing with infants who have sacral dimples, it is essential to be aware of the characteristics of atypical dimples.
Spina bifida (SB; /ˌspaɪnə ˈbɪfɪdə/, [9] Latin for 'split spine') [10] is a birth defect in which there is incomplete closing of the spine and the membranes around the spinal cord during early development in pregnancy. [1]
All forms involve the pulling of the spinal cord at the base of the spinal canal, literally a tethered cord. [1] The spinal cord normally hangs loose in the canal, free to move up and down with growth, and with bending and stretching. A tethered cord, however, is held taut at the end or at some point in the spinal canal.

Following is a list of spinal nerves and points that are characteristically belonging to the dermatome of each nerve: [4] Dermatomes of the lower limb (modified, from Fender, after Foerster) C2 – At least one cm lateral to the occipital protuberance at the base of the skull. Alternately, a point at least 3 cm (1.2 in) behind the ear.
The spinal nerves arise from the spinal column. The top section of the spine is the cervical section, which contains nerves that innervate muscles of the head, neck and thoracic cavity, as well as transmit sensory information to the CNS. The cervical spine section contains seven vertebrae, C-1 through C-7, and eight nerve pairs, C-1 through C-8.
The hairs come in an assortment of colours and may be long or short; single, in clusters, or in tufts; thinner at the point or clubbed at the end. A spine may either be a chalaza (having a single point) or a scolus (having multiple points). The warts may either be small bumps or short projections on the body.
The stratified squamous epithelium of the congenital dermal sinus tract can extend to the spinal fascia of the dura mater or all the way to the spinal cord. [ 4 ] [ 5 ] Thus, the congenital dermal sinus forms a point of entry for infection, this can allow for the formation of an abscess , especially among children.
