This ligament can become stressed during aggressive physical activities and sports that may cause the arching of the spine. If it becomes strained or injured, it may result in problems similar to those of a typical iliolumbar ligament injury. The ossified, or bony, sacrotuberous ligament may be a critical factor in different types of neurovascular compression syndromes (the abnormal compression of nerves and blood vessels). An anatomical understanding of this ligament is crucial in order for patients to receive proper treatment for this clinical condition.
Long bones follow the process of endochondral ossification where the diaphysis grows inside of cartilage from a primary ossification center until it forms most of the bone. The epiphyses then grow from secondary ossification centers on the ends of the bone. A small band of hyaline cartilage remains in between the bones as a growth plate. As we grow through childhood, the growth plates grow under the influence of growth and sex hormones, slowly separating the bones. At the same time the bones grow larger by growing back into the growth plates. This process continues until the end of puberty, when the growth plate stops growing and the bones fuse permanently into a single bone. The vast difference in height and limb length between birth and adulthood are mainly the result of endochondral ossification in the long bones.
