The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which it is partly blended), to the lower transverse sacral tubercles and the lateral margins of the lower sacrum and upper coccyx. Its oblique fibres descend laterally, converging to form a thick, narrow band ...
Sacroiliac joint. Human female pelvis, anterior view, with sacroiliac joint within red ellipse. The sacroiliac joint or SI joint (SIJ) is the joint between the sacrum and the ilium bones of the pelvis, which are connected by strong ligaments. In humans, the sacrum supports the spine and is supported in turn by an ilium on each side.
Sacroiliac joint dysfunction is an outcome of either extra-articular dysfunction or from intraarticular dysfunction. SI joint dysfunction is sometimes referred to as "sacroiliac joint instability" or "sacroiliac joint insufficiency" due to the support the once strong and taut ligaments can no longer sustain. [8][9][2][12] When the joint is ...
An ankle fracture is a break of one or more of the bones that make up the ankle joint. [1] Symptoms may include pain, swelling, bruising, and an inability to walk on the injured leg. [1] Complications may include an associated high ankle sprain, compartment syndrome, stiffness, malunion, and post-traumatic arthritis. [1][2]
Treatment. Orthopedic casting, ORIF, CRIF. The Maisonneuve fracture is a spiral fracture of the proximal third of the fibula associated with a tear of the distal tibiofibular syndesmosis and the interosseous membrane. There is an associated fracture of the medial malleolus or rupture of the deep deltoid ligament of the ankle.
The major function of the interosseous sacroiliac ligament is to keep the sacrum and ilium together. [ 2 ] This prevents abduction or distraction of the sacroiliac joint. [ 2 ] It also helps to bear the weight of the thorax, upper limbs, head, and neck. This is performed by the nearly horizontal direction of the fibers running perpendicular ...
The Danis–Weber classification (often known just as the Weber classification) is a method of describing ankle fractures. It has three categories: [1] Type A. Fracture of the fibula distal to the syndesmosis (the connection between the distal ends of the tibia and fibula). Typical features: below level of the ankle joint; tibiofibular ...
A high ankle sprain, also known as a syndesmotic ankle sprain (SAS), is a sprain of the syndesmotic ligaments that connect the tibia and fibula in the lower leg, thereby creating a mortise and tenon joint for the ankle. High ankle sprains are described as high because they are located above the ankle. They comprise approximately 15% of all ...
