Interphalangeal is a term used in anatomy to describe the joints between the bones of the fingers and toes. Despite its long and complex appearance, the spelling of this word can be easily explained by its IPA phonetic transcription of ɪn.tər.fə.læn.dʒi.əl. The word is made up of three parts: "inter" meaning "between," "phalanx" meaning "bone of the finger or toe," and the suffix "-eal" meaning "relating to." By breaking it down in this way, the spelling of interphalangeal becomes more understandable.
Interphalangeal (adj.) is a medical term used to describe the anatomical relationship or location between the phalanges, which are the bones that make up the fingers and toes. Specifically, it refers to the joints located between these bones. The prefix "inter-" denotes the concept of "between" or "among," while "phalangeal" pertains to the phalanges.
There are two sets of interphalangeal joints known as proximal interphalangeal (PIP) joints and distal interphalangeal (DIP) joints. The PIP joints are present in the middle section of the fingers and toes, connecting the proximal phalanges to the middle (intermediate) phalanges. On the other hand, the DIP joints are located at the tips of the fingers and toes, joining the middle phalanges to the distal phalanges.
Interphalangeal joints are classified as hinge joints, allowing for flexion and extension movements. These joints are crucial for the range of motion and overall function of the fingers and toes.
Diseases or conditions that affect interphalangeal joints include arthritis, such as rheumatoid arthritis or osteoarthritis, which can cause pain, stiffness, and deformity. Injuries such as dislocation or fractures can also occur at these joints. Medical professionals may evaluate interphalangeal joints through physical examination, imaging techniques such as X-rays, and other diagnostic tests to determine the best treatment approach for any related conditions.

The word "interphalangeal" is derived from Greek roots. "Inter" means "between" in Greek, and "phalange" refers to a bone in the finger or toe. Therefore, "interphalangeal" literally means "between the phalanges". It is typically used to describe the joints that are located between the bones (phalanges) in the fingers or toes.
