Which type of traction is commonly used for nerve root disorders?

The use of Buck's traction for nerve root disorders is based on its ability to relieve pressure on the spinal nerves and alleviate pain. This type of traction is characterized by the application of a pulling force along the longitudinal axis of the body, effectively decompressing the intervertebral discs and nerve roots. By providing this decompression, Buck's traction helps to manage symptoms associated with nerve root disorders, such as radiculopathy or sciatica, which can result from conditions like herniated discs or spinal stenosis.

In contrast, the other types of traction mentioned serve different purposes or target different conditions. Dunlop traction is typically employed for certain pediatric orthopedic issues, usually involving fractures or dislocations in children. Russell's traction is often utilized for the treatment of femoral fractures and involves a more complex system that addresses the alignment of long bone fractures rather than directly focusing on nerve root disorders. Bryant's traction is specifically designed for young children with femur fractures, allowing for immobilization and alignment during the healing process.

Therefore, Buck's traction stands out as the most appropriate choice when considering traction methods aimed at alleviating nerve root disorders due to its decompression capability along the spinal axis.
