In human anatomy, the annular ligaments of the fingers, often referred to as A pulleys, are the annular part of the fibrous sheathes of the fingers.Four or five such annular pulleys, together with three cruciate pulleys, form a fibro-osseous tunnel on the palmar aspect of the hand through which passes the deep and superficial flexor tendons.
English: Annular and cruciform parts of fibrous sheath over (synovial) flexor tendon sheaths Deutsch: Ringförmige („Ringband“ A1–A5) und gekreuzte (C0–C3) Teile der Sehnenscheide über den Beugesehnen des Zeigefingers der rechten Hand
The number and extent of these cruciate and annular ligaments varies among individuals, but three cruciate and four or five annular ligaments are normally found in each finger (usually referred to as, for example, "A1 pulley" and "C1 pulley"). The thumb has a similar system for its long flexor tendon but with a single oblique pulley replacing ...
The inferior extensor retinaculum of the foot (cruciate crural ligament, lower part of anterior annular ligament) is a Y-shaped band placed in front of the ankle-joint, the stem of the Y being attached laterally to the upper surface of the calcaneus, in front of the depression for the interosseous talocalcaneal ligament; it is directed medialward as a double layer, one lamina passing in front ...
The two ligaments are called "cruciform" ligaments, as they are arranged in a crossed formation. In the quadruped stifle joint (analogous to the knee), based on its anatomical position, it is also referred to as the cranial cruciate ligament. [1] The term cruciate is Latin for cross. This name is fitting because the ACL crosses the posterior ...
The underlying mechanism involves slippage of the annular ligament off of the head of the radius followed by the ligament getting stuck between the radius and humerus. [1] Diagnosis is often based on symptoms. [2] X-rays may be done to rule out other problems. [2] Prevention is by avoiding potential causes. [2] Treatment is by reduction. [2]
[10] [15] The results demonstrated poor resistance to torsion forces. [11] Approved by FDA in 1986 and adopted in clinics later, Gore-Tex cruciate ligament prosthesis demonstrated low rates of mechanical failure but high rates of rupture in follow-up. [16] Gore-Tex was then abandoned in ACL surgery and Leeds-Keio (LK) ligament was then adopted ...
The annular ligament (orbicular ligament) is a strong band of fibers that encircles the head of the radius, and retains it in contact with the radial notch of the ulna. [ 1 ] Per Terminologia Anatomica 1998 , the spelling is "anular", [ 2 ] but the spelling "annular" is frequently encountered.
