- Is There a Condition Where the Muscle Turns Into a Bone?

- QUESTION: Is there a condition where the muscle turns into a bone? A friend
- of mine had an x-ray of his arm, and there was a piece of bone seen that
- normally isn't there. The doctor says that the only way to treat it is to
- remove it with an operation, but wants to wait a while to see how big it is
- going to get. Is this right? Please help us.

- ANSWER: The condition is one that is known, and bears the impressive name of
- "myositis ossificans"; but it really isn't muscle turning into bone, although
- that is the meaning of the translation of these words which come to us from
- the both the Greek ("myo" means "muscle") and the Latin ("ossificans" means
- "to make bone"). Actually the process begins with an injury, usually a
- contusion or strain, in which the muscle is torn, and blood collects in a clot
- called a "hematoma". The most common spot for these types of injuries are the
- thigh, followed by the mid arm. The bone formation usually only occurs on
- severe injuries, and may also involve a clot infection after a respiratory
- infection. Slowly the clot is transformed into bone, possibly from bone cells
- which came from an injury to the covering of the bone (periosteum) which might
- have occurred at the same time. The bony mass keeps enlarging for as long as
- six or seven weeks, after which a process of resorption begins. Small masses
- may disappear completely, but when a large bone mass remains after a longer
- period of time, the only way to remove it is by using surgical techniques.
- Interestingly enough there is another situation in which such benign bone
- growth may be seen, and it is called "drug user's elbow". Here the process
- starts with the injuries to muscles and surrounding tissues that have been
- caused by the unskilled use of a needle that was in search of a vein, but
- instead ripped the other tissues in the area. The brachialis muscle of the
- upper arm is the muscle most commonly injured. If your friend's doctor
- believes that his injury is recent, he is correct in waiting a bit to see
- what develops before attempting to remove abnormal bone.
