AdministratorWhat is a P2 bone on a horse?
Fractures of the second/middle phalanx (P2) are most common in Quarter horses and typically affect the hindlimbs. Whereas osteochondral “chip” fractures are common off of proximal P1, osteochondral fractures are relatively uncommon off of P2.
What is the third Phalange?
There are fourteen phalanges in each hand; each of the medial four digits has three phalanges (proximal, middle and distal), while the thumb has only two (proximal and distal).
What is P1 and P2 in hand?
Each finger is divided into three phalanges except for the thumb with only two phalanges. The hand is consequently composed of 14 phalanges including: Five proximal phalanges (P1) Four middle phalanges (P2) for the long fingers.
What is P3 bone?
The coffin bone, also known as the pedal bone (U.S.), is the bottommost bone in the front and rear legs of horses, cattle, pigs and other ruminants. In horses it is encased by the hoof capsule. Also known as the distal phalanx, third phalanx, or “P3”.
What is a P2 fracture?
A, Dorsal PIPJ fracture-dislocation. The middle phalanx (P2) is dislocated or subluxated dorsally, and the volar lip is fractured at its base. The “V” sign (arrow) indicates dorsal instability. Note that the volar plate (VP) attachment is involved in the fracture.
What is a P2 fracture of finger?
The middle phalanx (P2) is dislocated or subluxated dorsally, and the volar lip is fractured at its base. The “V” sign (arrow) indicates dorsal instability. Note that the volar plate (VP) attachment is involved in the fracture.
What are MCP and PIP joints?
The interphalangeal joints of the hand are the hinge joints between the phalanges of the fingers that provide flexion towards the palm of the hand. The DIP, PIP and MCP joints of the hand: Distal InterPhalangeal. Proximal InterPhalangeal.
Is P3 the coffin bone?
The coffin bone is the lowest bone in the horse’s leg and is also known as P3, Distal Phalanx and the Pedal Bone. It is encased in the hoof capsule (as if in a coffin) and is attached to the inner wall of the hoof by the laminae.
Where is P3 on a horse?
The caudal (back) of the hoof is formed by and lies between the lateral cartilages. The foundation for the lateral cartilages is P3.
What are the P1 P2 and P3 joints called?
The joints are named the MC/MT-P1, P1-P2 and P2-P3 joints. Ligaments are the tissues that connect each of the bones at the joint. There are also ligaments that attach the sesamoids to the end of the metacarpal/metatarsal bone. Bones (P1, P2 & P3), joints & ligaments of the dog toe.
What is the difference between P1 and P2 fractures?
Whereas osteochondral “chip” fractures are common off of proximal P1, osteochondral fractures are relatively uncommon off of P2. The most common fractures of P2 are either palmar/plantar eminence fractures of proximal P2 or comminuted fractures.
What is the difference between p1 p2 and P3?
The first phalange (P1) is called the proximal phalange, the second one (P2) middle phalange, and the third one (P3) distal phalange. These long bones also have a convex back side and a concave palm side. The third phalange ends up in the phalangeal tuft.
What does P2 mean on a horse’s hoof?
P2 – P2 is actually the middle phalanx. The lower portion of this bone is in the hoof capsule and the upper portion helps make up the pastern. 4. P1 – P1 is the Proximal Phalanx.
