What is landsmeer ligament?

Introduction Landsmeer ligaments play a significant role in synchronizing the movements of the two distal phalanges of the fingers. Aim To ascertain and redefine the detailed anatomy of Oblique Retinacular (ORL) and Transverse Retinacular ligaments (TRL) and their applied features.

What is the function of the oblique Retinacular ligament?

Located in the finger, the oblique retinacular ligament (ORL) is believed to aid in stabilization of the proximal interphalangeal (PIP) joint. The ORL originates at the base of the proximal phalanx and courses obliquely past the PIP joint to terminate on the dorsum of the distal phalanx (Figure 1).

What is Checkrein ligament?

Check rein ligaments. The volar plate is a fibrocartilagenous thickening that stabilizes the proximal interphalangeal (PIP) joint and prevents hyperextension. The proximal end of the volar plate is free and attached to the proximal phalanx by the check rein ligaments.

What are the finger ligaments?

Fingers are constructed of ligaments (strong supportive tissue connecting bone to bone), tendons (attachment tissue from muscle to bone), and three phalanges (bones). There are no muscles in the fingers; and fingers move by the pull of forearm muscles on the tendons.

Do finger ligaments heal on their own?

Most ligament injuries within a finger heal without complication in a matter of weeks. However, a proportion of injuries can result in longer-term effects, depending on the severity of the injury and extent of damage.

How do you test for tightness in Orl?

Test: Passively flex the DIP joint. Rule out PIP joint contracture by repeating with the PIP joint flexed. Interpret: ORL tightness is present if DIP joint motion is greater when PIP is flexed than when extended. DIP joint contracture is present if position of PIP does not influence DIP flexion.

What is Elson’s test?

The Elson test is a diagnostic test used for early detection of injuries to the central slip of the extensor tendon.

How do you know if you have a torn ligament in your finger?

When a ligament supporting a finger joint is injured pain is felt in the finger. It is often made more painful if the joint is moved or if the finger is touched where the ligament is injured. Shortly after the injury the finger will become swollen and then bruised.

How do you strengthen finger ligaments?

DIP flexion

1. With your good hand, grasp your affected finger. Your thumb will be on the top side of your finger just below the joint that is closest to your fingernail.
2. Slowly bend your affected finger only at the joint closest to your fingernail. Hold for about 6 seconds.
3. Repeat 8 to 12 times.
