2023年11月9日 · The proximal interphalangeal (PIP) joints of the fingers are extremely important for gripping things with hands, more specifically, what is called the ‘power’ grip. Being a hinge joint, the joint’s articular surface and soft tissue do not permit any lateral movement.

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. [1

2023年10月30日 · The proximal interphalangeal joint (PIPJ or PIJ) is located between the proximal and middle phalanges, while the distal interphalangeal joint (DIPJ or DIJ) is found between the middle and distal phalanges. Since the first digit only has a proximal and distal phalanx, the joint between them is simply known as the interphalangeal joint of the thumb.

2024年10月28日 · The proximal interphalangeal joint (PIPJ) refers to the articulation between the proximal and middle phalanx in the hand. It is present in all digits except the thumb. It is a synovial hinge joint which permits flexion and extension in center …

The PIP joint is the first joint of the finger and is located between the first two bones of the finger. The PIP joint can bend and extend the finger. It becomes stiff easily after injury.

2025年2月17日 · The proximal interphalangeal joint (PIPJ) is the hand’s articulation between the proximal and middle phalanx. It is found in every digit except for the thumb. The bending and extension of the fingers in the middle are made possible by this synovial hinge joint, which aids in fine motor control. 1. Arthritis. 2. Injuries & Dislocations. 3.

2021年8月16日 · The proximal interphalangeal joint (PIPJ) is a bicondylar, synovial, hinge joint. The articular surfaces of the proximal and middle phalanx are stabile in saggital movements (flexion and extension) but have limited tolerance to angular, axial, and rotational stress.

2024年11月19日 · Arthritis of the DIP and PIP joints are very common forms of osteoarthritis seen in the hand and can be associated with pain and deformity. Diagnosis is made radiographically with joint space narrowing seen in the DIP and PIP joints of the fingers. Mucous cysts are often present on clinical inspection of the DIP joint.

2021年11月16日 · Interphalangeal (IP) joints of the hand are hinge-type synovial joints between adjacent phalanges. The thumb has a single interphalangeal joint, and the second to fifth digits each have a proximal and a distal interphalangeal joint. The head of the more proximal phalanx articulates with the base of the more distal phalanx.

The PIP Joint provides an articulation between: Proximal Phalanx; Middle Phalanx; Ligaments: Collateral Ligaments; Tendons crossing the PIP Joint: Flexor Digitorum Superficialis (FDS) Extensor Digitorum; IP joint type: Hinge joint; Synovial joint. Synovial joints are specialized structures that allow movement at bony articulations.
