Pronator teres syndrome
Pronator Teres Syndrome
Pronator teres syndrome (pronounced: pro-nay-tor te-res sin-drome) is a neuromuscular disorder that occurs when the median nerve is compressed at the elbow. The median nerve runs down the arm and provides sensation to the palm side of the thumb and fingers, excluding the little finger.
Etymology
The term "pronator teres" is derived from Latin, where "pronator" means "to turn face down" and "teres" means "round". The syndrome is named after the pronator teres muscle, which is one of the muscles involved in turning the palm of the hand downwards.
Symptoms
Symptoms of pronator teres syndrome may include pain in the forearm and hand, numbness or tingling in the palm, thumb, or first three fingers, and weakness in hand grip. These symptoms are often exacerbated by physical activities that involve repetitive forearm rotation and wrist flexion.
Diagnosis
Diagnosis of pronator teres syndrome is typically based on a physical examination and the patient's symptoms. Additional tests such as electromyography (EMG) and nerve conduction studies may be used to confirm the diagnosis and rule out other conditions such as carpal tunnel syndrome.
Treatment
Treatment for pronator teres syndrome often involves conservative measures such as rest, physical therapy, and nonsteroidal anti-inflammatory drugs (NSAIDs). In severe cases, surgery may be required to decompress the median nerve.
