It is more of a cord-like structure. The lateral ulnar collateral ligament was identified bilaterally over the radi-al head in all 35 volunteers.
The two-level ulnar collateral ligament injury of the metacarpophalangeal joint of the thumb. Gross anatomy. The lateral ulnar collateral ligament (LUCL) of the elbow is a primary stabilizer of the elbow joint to varus and external rotatory stress 1-6.

On the ulnar aspect of the metacarpophalangeal (MCP) joint of the thumb are seen the transverse and oblique fibers of the adductor pollicis aponeurosis (and some muscle fibers), inserting into the extensor pollicis longus (EPL) tendon, and all overlying the ulnar collateral ligament.

It attaches to the end of the ulna’s styloid process. The lateral ulnar collateral ligament (LUCL) of the elbow is a primary stabilizer of the elbow joint to varus and external rotatory stress 1-6.. The UCL is rarely stressed in daily activities. The medial (ulnar) collateral ligament (MCL/UCL) complex is a major stabilizer of the elbow joint and resists valgus stress. The ulnar collateral ligament (UCL, also known as medial collateral ligament) is located on the medial side of the elbow.The UCL complex comprises three ligaments: the anterior oblique, posterior oblique and transverse ligaments.

Ulnar collateral ligament (elbow) Left elbow-joint, with arrows pointing at the ulnar collateral ligament. The lateral (radial) collateral ligament (LCL) also supports the ulnohumeral and radiohumeral joints, but laterally. �;� x�]�� 3 0 obj Posterolateral rotatory instability of the elbow is the most common chronic elbow instability.

O’Driscoll originally described the concept of posterolateral rotatory instability (PLRI), a specific instability pattern which results when the ulna rotates on its long axis, distracting the radial aspect of the ulnotrochlear joint.1Because the proximal radioulnar joint is stabilized by an intact annular ligament, the radius remains tightly coupled to the ulna.
