Final answer:
The Norgaard method, also known as the "ball-catcher's view," is an alternate radiographic technique to the Gaynor-Hart Carpal Tunnel Projection, useful for diagnosing conditions like carpal tunnel syndrome.
Step-by-step explanation:
The alternate method to the Gaynor-Hart Carpal Tunnel Projection is known as the Norgaard method or the "ball-catcher's view." This alternate radiographic technique is used for visualizing the carpal tunnel to assess for conditions such as carpal tunnel syndrome. While the Gaynor-Hart method involves hyperextending the patient's hand to visualize the carpal canal, the Norgaard method positions the hands in a way resembling someone holding a large ball, with the dorsum of the hands touching and fingers pointing upwards, and the X-ray beam directed at the palms. This view aids in diagnosing conditions affecting the carpometacarpal joint articulation and can be used to visualize the arrangement of the carpal bones and any anomalies or changes that could compress the median nerve leading to carpal tunnel syndrome.
