Entrapment
Entrapment (en-trap-ment)
Entrapment is a medical term referring to a condition where a nerve is compressed or constricted in a rigid area of the body, leading to pain, numbness, muscle weakness, and often impairing normal function.
Etymology
The term "entrapment" originates from the English word "trap", which means to catch or ensnare. In a medical context, it refers to a nerve being "caught" or "trapped" in a confined space.
Definition
Entrapment in medicine is a condition where a nerve is compressed or constricted, often within a narrow passage in the body. This can occur due to various reasons such as inflammation, injury, or anatomical abnormalities. The pressure on the nerve can disrupt its function, leading to symptoms such as pain, numbness, tingling, or muscle weakness.
Symptoms
Symptoms of entrapment can vary depending on the specific nerve involved and the severity of the compression. Common symptoms include:
- Pain
- Numbness
- Tingling
- Muscle weakness
- Impaired function of the affected area
Causes
Entrapment can be caused by a variety of factors, including:
- Inflammation: Swelling in the body can put pressure on nerves, leading to entrapment.
- Injury: Trauma to the body can cause nerves to become compressed.
- Anatomical abnormalities: Certain conditions or deformities can cause narrow passages in the body, leading to nerve compression.
