Understanding Carpal Tunnel Syndrome (CTS)

What Causes Carpal Tunnel Syndrome?
Within your wrist lies a crucial structure known as the carpal tunnel, formed by eight bones. This tunnel houses vital tendons and the median nerve responsible for sensation in the palm side of your first 3 ½ fingers. Compression or irritation of this nerve within the carpal tunnel leads to Carpal Tunnel Syndrome (CTS), the most prevalent nerve entrapment condition, affecting 3-5% of the population. CTS predominantly impacts adults aged 45-60, with females experiencing it more frequently than males.
Risk Factors for CTS
Prolonged wrist flexion and repetitive motions such as keyboard use, carpentry, or assembly line work can cause CTS. Additionally, exposure to vibration or cold can exacerbate the condition. While CTS often affects the dominant hand, it can occur bilaterally. Risk factors include diabetes, thyroid disease, rheumatoid arthritis, alcoholism, kidney disease, being short or overweight, and fluid retention during pregnancy.
Recognizing CTS Symptoms
Symptoms of CTS manifest as numbness, tingling, or discomfort in the palm side of the thumb, index, middle finger, and half of the ring finger. Pain may extend to the elbow, initially presenting as nighttime discomfort or waking up with numb hands. Activities requiring grip, such as reading or driving, can worsen symptoms. In severe cases, hand weakness may occur.
Treatment Strategies
CTS often involves compression at multiple sites, termed "double crush syndrome," including the spine, neck, shoulder, and forearm muscles. Avoiding activities involving repetitive wrist flexion and using a splint to maintain a neutral or slightly extended wrist position can alleviate symptoms. Exercises like pushups or gripping bicycle handlebars may exacerbate CTS and should be avoided.
Recovery and Management
Untreated CTS can lead to permanent nerve damage in the forearm. Conservative treatments, like those offered in our office, are recommended by the American Academy of Neurology before considering surgery. Our comprehensive approach aims to alleviate symptoms and restore optimal hand function, promoting long-term well-being.
