Arcuate ligament

Arcuate ligament is part of the posterolateral ligamentous complex of the knee. It is a Y-shaped thickening of the posterolateral capsule, which arises from the fibular styloid and divides into two limbs: medial limb: curves over the popliteus muscle to join with the oblique popliteal ligament ...

Iliolumbar ligament

The iliolumbar ligament is a strong band of connective tissue which courses from the transverse process of L5 (in over 96% of cases) to the posterior iliac wing and iliac crest. It functions to maintain the alignment of L5 on the sacrum during various movements 1, 2.  It is an important landmar...

Acetabular labrum

Acetabular labrum acts to deepen the acetabulum and increase contact between the pelvis and the femoral head. Its exact biomechanical role remains to be fully elucidated. Gross anatomy The acetabular labrum is a C-shaped fibrocartilaginous structure with an opening anteroinferiorly at the site...

Anterior cruciate ligament

Anterior cruciate ligament (ACL) is one of the two cruciate ligaments that stabilise the knee joint.  Gross anatomy The ACL arises from the anteromedial aspect of the intercondylar area on the tibial plateau and passes upwards and backwards to attach to the posteromedial aspect of the lateral ...

Posterolateral ligamentous complex

The posterolateral ligamentous complex (also known as the arcuate ligamentous complex) of the knee is an important stabiliser and consists of a number of structures. Depending on the publication/definition more or less of the following structures are included 1-4: lateral (fibular) collateral l...
Article

Triangular space of cruciate ligaments

Triangular space of cruciate ligaments (TSC) is defined as the potential extrasynovial space between anterior and posterior cruciate ligaments of the knee joint. Gross anatomy Boundaries anteriorly: anterior cruciate ligament posteriorly: posterior cruciate ligament inferiorly: tibial plate...

Lateral collateral ligament of the ankle

The lateral collateral ligament (complex) of the ankle is a set of three ligaments that resist inversion of the ankle joint. They are more commonly injured than the medial collateral (deltoid) ligament of the ankle. They run from the lateral malleolus of the fibula to the talus and calcaneus.  ...
Article

Calcaneofibular ligament

The calcaneofibular ligament (CFL) is the middle ligament of the lateral collateral ligament complex of the ankle and stabilises both the ankle and subtalar joints. Gross anatomy The CFL is an extracapsular round cord measuring 20-25 mm long x 6-8 mm width. Its origin is distal to the anterior...
Article

Posterior talofibular ligament

The posterior talofibular ligament (PTFL) is one of three ligaments that compose the lateral collateral ligament complex of the ankle. When the anterior talofibular and calcaneofibular ligaments are intact, it only has a secondary role in ankle joint stability and is also the least commonly inju...

Anterior longitudinal ligament

The anterior longitudinal ligament (ALL) arises from the anterior tubercle of the atlas, travels downwards, anterior to the vertebral bodies (firmly united to the periosteum) and intervertebral discs (attaching to the anterior annulus), attaching to the front of the upper part of the sacrum. It ...
Article

Anterior atlanto-occipital membrane

The anterior atlanto-occipital membrane joins the upper border of the anterior arch of the atlas to the outer margin of the foramen magnum.
Article

Apical ligament

The apical ligament joins the apex of the dens to the anterior margin of the foramen magnum. It is the weak, fibrous remnant of the notochord.
Article

Alar ligament

The alar ligaments join the lateral margins of the sloping upper margin of the dens to the margins of the foramen magnum (adjacent to the occipital condyles) and lie on either side of the apical ligament. They are paired ligaments that are very strong and limit rotation of the head.
Article

Cruciate ligament of the atlas

The cruciate ligament of the atlas (also known as the cruciform ligament) holds the dens in articulation at the atlanto-axial joint. It lies behind a large synovial bursa (surrounded by loose fibrous capsule) and consists of two bands: longitudinal band: joins the body of the axis to the forame...
Article

Posterior longitudinal ligament

The posterior longitudinal ligament (PLL) arises from the back of the axis (C2) body and travels downward and posterior to the vertebral bodies (attached loosely) and intervertebral discs (firmly attaching to the posterior annulus), attaching to the back of the sacrum. It narrows as it travels d...
Article

Tectorial membrane of the spine

The tectorial membrane is the continuation of the posterior longitudinal ligament from the body of the axis upward. It joins the axis body to the clivus on the anterior half of the foramen magnum. Spinal dura mater is firmly attached posteriorly, also serving as a ligament.
Article

Ligamentum flavum

The ligamentum flavum is a yellowish, elastic ligament, which runs between adjacent laminae (front of the upper lamina to the back of the lower lamina) and the bases of the spinous processes of the vertebral bodies. In the lumbar region, it runs laterally, covering the anterior aspect of the fac...
