Oct 30, 2023 · The palmar ligament (a.k.a palmar/volar plates) is a thick plate of fibrocartilage located on the palmar surface of each interphalangeal joint. This ligament has a characteristic upside down “U” shape, with its distal part arching across the base of the distally lying phalanx to blend with the accessory collateral ligaments.

The interphalangeal joints of the hand are the hinge jointsbetween the phalanges of the fingers that provide flexion towards the palm of the hand.
There are two sets in each finger (except in the thumb, which has only one joint) 1. Proximal interphalangeal joints" (PIJ or PIPJ), those between the first (also called proximal) 2. Distal interphalangeal joints" (DIJ or DIPJ), those between the second (intermediate) third (distal) phalanges Anatomically, the proximal and distal interphalangeal jo...
The function of the interphalangeal joints of the hand to permit fine motor movements in the digits. To accomplish this, these joints facilitate movement within only one degree of freedom: flexion - extension.
Palpation
1. 1.1. Gently squeeze across the joints in a methodical order, assessing for the nature of any swelling present 1.2. Remember that inflamed joints are painful and must be examined gently 1.2.1. Look at patient’s face if possible while palpating to discern any pain 1.3. Interphalangeal (IP) joint must be palpated in turn and compared to the opposite side. This is best done by holding the joint between your thumb and forefinger and palpating gently 1.3.1. If the swollen joint feels soft, warm...
Treatment
According to research, there is evidence that gentle exercise with osteoarthritis will assist with decreasing pain and increasing grip strengthand that joint protection techniques are effective at decreasing pain. Heat or paraffin may also be used to assist with decreasing pain and improving mobility. Additionally, a splint for the DIP joint is a common recommendation for the treatment of DIP joint arthritis. A cohort study of individuals with DIPJ arthritis had a 66% improvement in pain symp...
The collateral ligaments of the interphalangeal joints are the strong fibrous bands that attach to each side of the interphalangeal joint, holding the joint firmly in place. They extend obliquely from the dorsal surface of the proximal phalanx to the palmar surface of the distal phalanx (Dorland, 2011).
Dec 20, 2023 · Proper and accessory collateral ligaments: The collateral ligaments are located on the radial and ulnar aspect of the joint. They prevent excessive adduction and abduction at the PIPJ. They arise from the head of the proximal phalanx and pass volarly onto the middle phalanx, along the lateral aspect of the joint. Each collateral ligament is ...
The collateral ligaments of interphalangeal joints are ligaments of the interphalangeal joints of the hand. They limit extension at these joints (together with the palmar ligaments ). [1] On each side of the interphalangeal joints of the fingers are diagonally placed fibrous bands. The proximal ends of the bands are near the dorsal phalanges of ...
The palmar ligament is thinner and more flexible in its central-proximal part. On both sides it is reinforced by the so-called check rein ligaments. The accessory collateral ligaments (ACL) originate at the proximal phalanx and are inserted distally at the base of the middle phalanx below the collateral ligaments.
