What's the difference between retinaculum and underside?
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.

(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.

(12) The symptoms in one case were partially relieved by ligation of the radial artery distal to the fistula, and in both they were abolished by decompression of the median nerve by section of the flexor retinaculum at the wrist.

(19) It innervates the flexor retinaculum and the skin of the heel pad.
(20) The carpal tunnel syndrome is described as a compression of the N. medianus under the retinaculum flexorum with the causes for this syndrome being of the most varied nature.
Underside
Definition:
(n.) The lower or lowest side of anything.
