arcuate ligament

n.
1. A thickening of the fascia of the lumbar quadrate muscle, between the transverse process of the first lumbar vertebra and the twelfth rib on either side, that gives attachment to a portion of the diaphragm; lateral arcuate ligament.
2. A tendinous thickening of the fascia of the greater psoas muscle that extends from the body of the first lumbar vertebra to its transverse process on either side and from which a portion of the diaphragm arises; medial arcuate ligament.
3. A tendinous connection between the crura of the diaphragm that arches in front on the aorta; median arcuate ligament.

Median arcuate ligament syndrome (MALS) is a clinically rare disease resulting from extrinsic compression of the celiac trunk by fibrous attachments of the diaphragmatic crura, median arcuate ligament, which results in various clinical symptoms including postprandial abdominal pain, vomiting, and/or weight loss.

Complications such as aneurysm (Ailawadi et al., 2004), occlusive disease (Ailawadi et al.), compression by the median arcuate ligament (Lee et al., 2011) and stenosis with lethal consequences (Lovisetto et al., 2012) have only been described in adults.
Posterolateral corner is stabilised by the arcuate ligament complex which consists of lateral collateral ligament; biceps femoris tendon; popliteus muscle and tendon; popliteal meniscal and popliteal fibular ligaments; arcuate ligament, lateral gastrocnemius muscle and fabellofibular ligaments.
The pathogenesis behind celiac trunk stenosis maybe intrinsic in nature (e.g., caused by atherosclerosis or dysplasia) or extrinsic (e.g., caused by median arcuate ligament compression, which is seen in 10-24% of patients with celiac stenosis) [4].

It should also be mentioned that experimental and biomechanical studies have suggested the fabellofibular ligament (and arcuate ligament) to be less important for joint stabilization than the popliteal tendon and its associated popliteofibular ligament [4].
