2018年8月13日 · A proximal phalanx (plural: phalanges) is one of the tubular long bones [11] located in the bottom row of the phalanges or finger bones [1]. Each proximal phalanx has a head, a body/shaft, and a base. As the name suggests, they are the proximal row of the phalanges, located nearest to the metacarpals in the human hand [2].

2024年4月10日 · The proximal phalanx is the phalanx (toe bone) closest to the leg. The image shows a diagram of where these bones lie in the foot—the midpoint of the proximal phalanges being where to the toes branch off from the main body of the foot.

2025年2月4日 · Phalanx Fractures are common hand injuries that involve the proximal, middle or distal phalanx. Diagnosis can be confirmed with orthogonal radiographs of the involve digit. Treatment involves immobilization or surgical fixation depending on location, severity and alignment of injury.

2023年12月12日 · Designated by the name, they are located in the lowest row of the phalanges, being the closest to the metacarpals in the human hand [2]. There exists a single distal phalangeal bone in each finger (including the thumb), leading to the presence of five distal phalangeal bones in each hand, making the total count ten in both hands.

2023年11月13日 · Each hand has a total of five proximal phalanges, one in each digit. Compared to the middle and distal phalanges, they are the largest ones. The proximal phalanx of the thumb is an exception because it is shorter and more stout compared to the rest.

Proximal Phalanges: Located at the proximal end, articulating with the metacarpals [6]. Middle Phalanges: Located in the middle, between the proximal phalanges and distal phalanges. The middle phalanx is not present in the human thumb, which only …

Proximal phalanges of the hand. Location/Articulation. The proximal extremities of the bones of the first row present oval, concave articular surfaces, broader from side to side than from front to back. The proximal extremity of each of the bones of the second and third rows presents a double concavity separated by a median ridge.

2025年1月16日 · The base of proximal phalange is a concave articular surface that create the metacarpophalangeal joint with the distal part of the metacarpal bone. [1] Head of proximal phalanges has a cylinder-shaped articular surface.

2020年12月13日 · Proximal Phalanx. The structure indicated is the proximal phalanx of the 5 th finger. The hand consists of three groups of bones: Carpals; Metacarpals; Phalanges; The phalanges (phalanx = singular), form the fingers/digits of the hands. The thumb consists of two phalanges: proximal phalanx and distal phalanx. The rest of the fingers consist of ...

The proximal phalanx has five basic parts: The head or distal epiphysis, the neck or metaphysis, the shaft or diaphysis, the proximal metaphysis, and the base or proximal epiphysis. The concave proximal ends of the proximal phalanx articulate with the metacarpals.
