	Sacrococcygeal Teratoma Sacrococcygeal teratoma (SCT) is a type of tumor known as a teratoma that develops at the base of the coccyx (tailbone) and is thought to be primarily derived from remnants of the primitive streak. Sacrococcygeal teratomas are benign 75% of the time, malignant 12% of the time, and the remainder are considered "immature teratomas" that share benign and malignant features. Benign sacrococcygeal teratomas are more likely to develop in younger children who are less than 5 months old, and older children are more likely to develop malignant sacrococcygeal teratomas. The Currarino syndrome, due to an autosomal dominant mutation in the MNX1 gene, consists of a presacral mass (usually a mature teratoma or anterior meningocele), anorectal malformation and sacral dysgenesis. Presentation Complications Maternal complications of pregnancy may include mirror syndrome. Maternal complications of delivery may include a Cesarean section or, alternatively, a vaginal delivery with mechanical dyst ...

	Anterior Sacrococcygeal Ligament The anterior sacrococcygeal ligament or ventral sacrococcygeal ligament consists of a few irregular fibers, which descend from the anterior surface of the sacrum to the front of the coccyx, blending with the periosteum.Morris (2005), p 59 This shortSinnatamby (2006), p 336 ligament forms the continuation of the anterior longitudinal ligament and stretches over the sacrococcygeal symphysis.OMD: DefinitionJinkins (2000), p 538Ebrall (2004), 243 See also * Posterior sacrococcygeal ligament * Coccydynia (coccyx pain, tailbone pain) * Ganglion impar The pelvic portion of each sympathetic trunk is situated in front of the sacrum, medial to the anterior sacral foramina.

	Posterior Sacrococcygeal Ligament The posterior sacrococcygeal ligament or dorsal sacrococcygeal ligamentOMD: Definition is a ligament which stretches from the sacrum to the coccyx and thus dorsally across the sacrococcygeal symphysis shared by these two bones. This ligament is divisible in two parts: A short deep part which unites the two bones, and a larger superficial portion which completes the lower back part of the sacral canal. On either side, two lateral sacrococcygeal ligaments run between the transverse processes of the coccyx and the inferior lateral angle of the sacrum.Sinnatamby (2006), p 336 It is in relation, behind, with the gluteus maximus. Deep part The deep dorsal sacrococcygeal ligament (ligamentum sacrococcygeum posterius profundum) is a continuation of the posterior longitudinal ligament. A flat band arising inside the sacral canal, posteriorly at the orifice of the fifth sacral segment, it descends to the dorsal surface of the coccyx under its longer fellow described below.Morris (200 ...

	Sacrococcygeal Symphysis The sacrococcygeal symphysis (sacrococcygeal articulation, articulation of the sacrum and coccyx) is an amphiarthrodial joint, formed between the oval surface at the apex of the sacrum, and the base of the coccyx. It is a slightly moveable jointMorris (2005), p 59 which is frequently, partially or completely, obliterated in old age,Palastanga (2006), p 334 homologous with the joints between the bodies of the vertebrae. Disc The sacrococcygeal disc or interosseus ligamentHuijbregts (2001), p 13 is similar to the intervertebral discs but thinner, thicker in front and behind than at the sides, and with a firmer texture. The articular surfaces are elliptical with longer transversal axes. The surface on the sacrum is convex and that on the coccyx concave. Occasionally the coccyx is freely movable on the sacrum, most notably during pregnancy; in such cases a synovial membrane is present. Ligaments The joint is strengthened by a series of ligaments: * The ventral or anterior sac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
