2011 ICD-9-CM Diagnosis Code 815.00 : Closed fracture of metacarpal bone(s) site unspecified.
The Fourth Metacarpal Bone (os metacarpale IV; metacarpal bone of the ring finger) is shorter and smaller than the third. The base is small and quadrilateral; its superior surface presents two facets, a large one medially for articulation with the hamate, and a small one laterally for the capitate.
A boxer's fracture is a break in the neck of the 5th metacarpal bone in the hand. It usually happens when you punch an object at a high speed. Symptoms of a boxer's fracture include pain and swelling of the hand, limited range of motion of the pinky finger, and misalignment of the finger.
metacarpal, any of several tubular bones between the wrist (carpal) bones and each of the forelimb digits in land vertebrates, corresponding to the metatarsal bones of the foot.
Metacarpal BonesMetacarpal I – Thumb.Metacarpal II – Index finger.Metacarpal III – Middle finger.Metacarpal IV – Ring finger.Metacarpal V – Little finger.
Besides the metacarpophalangeal joints, the metacarpal bones articulate by carpometacarpal joints as follows:the first with the trapezium;the second with the trapezium, trapezoid, capitate and third metacarpal;the third with the capitate and second and fourth metacarpals;More items...
The metacarpals of the fingers make up the bone structure of most of the hand. They are all similar in shape and have joints in the wrist on one end, and the finger at the other end. The index and middle finger metacarpals have very little motion, while the metacarpals of the ring and little finger move much more.
The second metacarpal bone (metacarpal bone of the index finger) is the longest, and its base the largest, of all the metacarpal bones.
middle fingerThird metacarpal bone The metacarpal bone 3 is located at the base of the middle finger. It differs from the others by a styloid process that projects proximally from the laterodorsal edge of its base. This process participates in the joint with the capitate bone.
Definition of metacarpal (Entry 2 of 2) : a bone of the part of the hand or forefoot between the carpus and the phalanges that typically contains five more or less elongated bones when all the digits are present.
First Metacarpal Joint/bone The first metacarpal bone is associated with the thumb. The joints between the carpals and the metacarpals are known as carpometacarpal joints. The joints between the metacarpals and the proximal phalanges are known a metacarpophalangeal joints.
The metacarpals are defined as long bones as they posses a tubular shaft with proximal (base) and distal (head) synovial articular extremities.
