Aug 8, 2023 · Each thumb (first digit) contains a proximal and distal phalanx, while the index (second digit), long (third digit), ring (fourth digit), and small (fifth digit) fingers all contain a proximal, middle, and distal phalanx. The proximal and middle phalanges can be subdivided into a base, shaft, and head from proximal to distal. The heads of the ...
Definitions. A pediatric middle phalanx fracture is a disruption of the mechanical integrity of the middle phalanx. A pediatric middle phalanx fracture produces a discontinuity in the middle phalanx contours that can be complete or incomplete. A pediatric middle phalanx fracture is caused by a direct force that exceeds the breaking point of the ...
Flex the patient's finger. The proximal phalanx is located between the proximal and the middle knuckle of the finger or between the palmar and the middle crease of the finger. The joint space of the MCP joint is located around 1 cm distal to the tip of the knuckle. Proximal, middle, and distal phalanges Interphalangeal joints
Definitions. A proximal phalanx fracture is a disruption of the mechanical integrity of the proximal phalanx. A proximal phalanx fracture produces a discontinuity in the proximal phalanx contours that can be complete or incomplete. A proximal phalanx fracture is caused by a direct force that exceeds the breaking point of the bone.
The middle phalanx of the finger is the middle or second of the three bones in each finger when counting from the hand to the tip of the finger. The middle phalanx has joints with the proximal phalanx and with the distal phalanx of the finger. Distal Phalanges. The distal phalanx of the finger is the distal or third of the three bones in each ...
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 has a proximal and a distal phalanx [7]. Distal Phalanges: The most terminal of all the phalanges, located at the end of the digits in hand [8].
The hand is distal to the forearm, and its skeletal framework includes the carpus, or wrist. In lay usage, however, the word "wrist" is used for the distal end of the forearm, a wrist-watch being worn over the lower ends of the radius and ulna. The position of the hand at rest is shown in figure 11-1. The hand is of enormous importance ...
