Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
A hammer toe, hammertoe or contracted toe is a deformity of the muscles and ligaments of the proximal interphalangeal joint of the second, third, fourth, or fifth toe, bending it into a shape resembling a hammer. In the early stage, a flexible hammertoe is movable at the joints; a rigid hammertoe joint cannot be moved and usually requires surgery.
Boutonniere deformity is a deformed position of the fingers or toes, in which the joint nearest the knuckle (the proximal interphalangeal joint, or PIP) is permanently bent toward the palm while the farthest joint (the distal interphalangeal joint, or DIP) is bent back away (PIP flexion with DIP hyperextension).
A hand imitating an ulnar claw. The metacarpophalangeal joints of the 4th and 5th fingers are extended and the Interphalangeal joints of the same fingers are flexed.. An ulnar claw, also known as claw hand or Spinster’s Claw, is a deformity or an abnormal attitude of the hand that develops due to ulnar nerve damage causing paralysis of the lumbricals.
If the problem has been present a long time surgery may also be required. [6] An open fracture may be another reason. Surgery will put the finger in a neutral position and drill a wire through the distal interphalangeal joint (DIP) to the proximal interphalangeal joint (PIP), forcing immobilization.
Trauma deformities may manifest as reduced joint function due to lack of coordination in phalangeal joints, such as proximal interphalangeal flexion and distal interphalangeal hyperextension in boutonnière deformity. [1] Besides trauma, another reason boutonnière deformity may develop is due to a chronic disease like rheumatoid arthritis. [1]
Flexor digitorum superficialis (flexor digitorum sublimis) or flexor digitorum communis sublimis [1] is an extrinsic flexor muscle of the fingers at the proximal interphalangeal joints. It is in the anterior compartment of the forearm .
These bones are designated the proximal phalanx (closest to the palm), the middle phalanx, and the distal phalanx (farthest from the palm). The joints between these bones are referred to as the proximal interphalangeal joint (PIP, between the proximal and middle phalanx) and the distal interphalangeal joint (DIP, between the middle and distal ...
