What's the difference between ligament and retinaculum?
Ligament
Definition:
(n.) Anything that ties or unites one thing or part to another; a bandage; a bond.
(n.) A tough band or plate of dense, fibrous, connective tissue or fibrocartilage serving to unite bones or form joints.
(n.) A band of connective tissue, or a membranous fold, which supports or retains an organ in place; as, the gastrophrenic ligament, connecting the diaphragm and stomach.

Retinaculum
Definition:
(n.) A connecting band; a fraenum; as, the retinacula of the ileocaecal and ileocolic valves.
(n.) One of the annular ligaments which hold the tendons close to the bones at the larger joints, as at the wrist and ankle.
(n.) One of the retractor muscles of the proboscis of certain worms.
(n.) A small gland or process to which bodies are attached; as, the glandular retinacula to which the pollinia of orchids are attached, or the hooks which support the seeds in many acanthaceous plants.
Example Sentences:
(1) The operation revealed a necrotic focus of the patellar tendon in 21 cases, the retinaculum was thick and adherent in 16 patients and an exostosis of the patellar insertion was seen in two cases.

(4) We consider them to be bony origins of ligaments: at the sciatic tuber--the bony origin of the sacrotuberal ligament, at the distal fibula--the bony origin of the peroneal compartment of the retinaculum mm extensorum inferius.
(5) Division of the retinaculum flexorum leads to free tendon movement and prevents further tendon degeneration.
(6) It is concluded that: 1) a chronic painful anterior lower leg syndrome should be suspected in patients with pain on walking and at rest located in the ventral part of the lower leg; 2) intracompartmental pressure measurements seem to be of little preoperative diagnostic value in non-selected patients; 3) blind diathermic fasciotomy of the anterior, medial compartment of the lower leg, including the extensor retinaculum, gives relief from pain and paresis in most patients with a typical history.
(7) Restoring stability to the ulna as well as reconstructing a new sheath for the extensor carpi ulnaris can be accomplished in most cases by using the extensor retinaculum.
(8) To arrive at on-target therapy directed etiologically at the root cause of the disease, it will be necessary to differentiate them from one another: insertion tendopathies of the achilles tendon; metabolic diseases; arthritis and chondropathic disease of the ankle joint; hallux rigidus --rotation anomalies; tibia vara; os trigonum impingement syndrome --tendovaginitis of the flexor tendon at the retinaculum flexorum; stress fractures (calcaneus, fibula, tibia) Diagnosis is assisted, besides a detailed and exact clinical examination and an inspection of the sports shoes worn by the patient, by a biomechanical analysis of the running behaviour, an x-ray of the ankle joint, sonographic examination and clarification with the help of laboratory examinations, i.e.
(9) Principal elements of this technique are an improvement of the bony containment of the tendons within the shallowed, malleolar sulcus and the use of the outer layer of the dislocation pouch as superior retinaculum.
