In preparing for mechanical cervical traction, how much neck flexion should be observed when the patient is in a supine position?

When preparing for mechanical cervical traction in a supine position, achieving a neck flexion of 25-35 degrees is important for properly targeting the cervical spine and effectively applying traction. This degree of flexion ensures that the intervertebral spaces are opened adequately, allowing for the desired benefits of traction such as alleviating pressure on the cervical discs and neural structures.

Proper neck flexion assists in positioning the vertebrae in such a way that traction can be applied in an effective manner without causing undue stress or discomfort to the patient. It allows for appropriate alignment and maximizes the therapeutic effect of the traction treatment.

While lesser degrees of flexion may not adequately open the cervical spine, greater degrees of flexion beyond 35 degrees could increase the risk of discomfort and potential complications by placing excessive strain on structures in the neck. Therefore, 25-35 degrees provides a balanced approach that facilitates effective treatment while ensuring patient safety and comfort.
