The deep dorsal sacrococcygeal ligament (ligamentum sacrococcygeum posterius profundum) is a continuation of the posterior longitudinal ligament. [1] 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. [3]
The dorsal or posterior sacrococcygeal ligament has a deep and a superficial part: The deep dorsal ligament is a flat band which corresponds to the posterior longitudinal ligament (PLL) that run down inside the vertebral canal on the posterior surfaces of the bodies of the vertebrae. From the posterior side of the fifth sacral body inside the ...
The anterior ligament is not much of a ligament at all and in most cases is just a slight thickening of the anterior joint capsule. The anterior ligament is thin and not as well defined as the posterior sacroiliac ligaments. The posterior sacroiliac (SI) ligaments can be further divided into short (intrinsic) and long (extrinsic). [9]
These can all be a source of pain and inflammation if the SI joint is dysfunctional. [9] [2] The sacroiliac joint is highly dependent on its strong ligamentous structure for support and stability. [9] The most commonly disrupted and/or torn ligaments are the iliolumbar ligament and the posterior sacroiliac ligament. [9]
Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). [2] As with any injury , an understanding of the anatomy and functional interactions of the posterolateral corner is important to diagnosing and treating the injury.
Other ways that coccydynia develops are partial dislocation of the sacrococcygeal synchondrosis that can possibly result in abnormal movement of the coccyx from excessive sitting, and repetitive trauma of the surrounding ligaments and muscles, resulting in inflammation of tissues and pain.
The lowest fibres of gluteus maximus are attached to the posterior surface of the ligament; superficial fibres of the lower part of the ligament continue into the tendon of biceps femoris. The ligament is pierced by the coccygeal branches of the inferior gluteal artery, the perforating cutaneous nerve and filaments of the coccygeal plexus. [2]
Sacrococcygeal ligament can refer to: Anterior sacrococcygeal ligament (ligamentum sacrococcygeum anterius) Lateral sacrococcygeal ligament (ligamentum sacrococcygeum laterale) Posterior sacrococcygeal ligament (ligamentum sacrococcygeum posterius) Deep posterior of the sacrococcygeal ligament (ligamentum sacrococcygeum posterius profundum)
