The vascular supply to the proximal interphalangeal joint
The Journal of Hand Surgery
|November 1, 1985
Summary
This study maps the vascular supply to the proximal interphalangeal joint using four methods. It identifies three key arterial branches crucial for joint perfusion and soft tissue nourishment.
Area of Science:
- Anatomy
- Vascular Anatomy
- Hand Surgery
Background:
- The proximal interphalangeal (PIP) joint is critical for hand function.
- Understanding its vascular supply is essential for reconstructive surgery and treating joint pathologies.
Purpose of the Study:
- To precisely identify and map the arterial vascular branches supplying the proximal interphalangeal joint.
- To elucidate the origin, course, and distribution of these vessels.
Main Methods:
- Utilized four distinct anatomical investigation techniques: intra-arterial radiopaque dye injection, microscopic arterial dissection, selective branch injection with subsequent joint examination, and histological sectioning.
- Examined 55 cadaveric fingers to comprehensively analyze the vascular architecture.
Main Results:
- Identified three primary arterial branches supplying the proximal interphalangeal joint.
- Major digital artery branches originate dorsally, supplying bone and joint structures, while smaller palmar branches supply soft tissues.
- Detailed the specific territories supplied by each of the three identified branches, including dorsal skin, bone, vincular system, lateral joint surfaces, palmar plate, and middle phalanx.
Conclusions:
- Established a detailed map of the arterial supply to the proximal interphalangeal joint.
- The identified vascular patterns provide critical anatomical data for surgical planning and understanding joint vascularization.

01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:16Muscles of the Forearm that Move the Hand and Fingers
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...

01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
01:20Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
01:17Veins of Upper Limbs
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
