What are the Metacarpals and Phalanges?
The red part is the metacarpals. The metacarpals connect the wrist with the fingers. The metacarpus part of the hand has five fingers known as the metacarpals.
The orange, blue, and green are all parts of the phalanges. The phalanges are digital bones in the hands and feet of most people and animals. They are also known as the fingers.
The neck of a metacarpal is a common location for a boxer’s fracture A boxer’s fracture is a fracture occurs transversely across the neck of the bone, after the patient strikes an object with a closed fist.
The Bennett's fracture is caused by hard impact of falling on the hand with your thumb sticking out. There will be rapid swelling and bruising. It will also make your hand look deformed. This is a severe injury that requires surgery. If not treated soon enough then it can cause permanent disability.
Compression of a nerve as it goes through the wrist, often making the fingers go numb. If it is not bad enough a splint can fix the problem. But if it is too bad, you may need to have surgery that will cut through the ligament to free the nerve.
Recovering from injuries
Therapy- joint hyperextension injuries may be treated by gently flexing the finger Surgery- surgery is only an option for a third degree sprain on the hyperextension
There are 14 different phalanges in each hand. There are three types of bones in the phalanges. proximal, middle, and distant
There are 19 bones in the hand (14 phalanges and 5 metacarpal)
The metacarpal bones have a head, body, and base
There are 17 muscles in the hand. Examples- Abductor Pollicis Brevis (thenar), Flexor Pollicis Brevis (thenar), Muscle Groups- thenar (thumb side of the palm), Hypothenar (Little finger side of the palm), and the Intermediate (Middle of hand)
Many 4 legged animals have phalanges and metacarpals
Finger joints only have wrinkles and creases if the joint moves. If a finger joint stops moving, the creases eventually flatten out.
