Mastering the Orthopedic Hand Exam: Tips for Quick and Accurate Assessment

👍Perform a systematic hand exam by assessing the joints above and below the affected area, as well as checking for sensory, motor, and neurovascular function.

✋The median nerve is responsible for opposition, flexion at the wrist and elbow, and pronation. Remember it as the 'tea-drinking' nerve.

👉The radial nerve controls the extensor mechanism of the wrist and can be remembered as the 'stop' nerve.

🖐️Be familiar with the flexor digitorum profundus and superficialis muscles to effectively evaluate hand function and diagnose injuries.

💪Proper assessment of the ulnar nerve is crucial, as it innervates the interosseous muscles and can cause ulnar nerve palsy.

What is the importance of performing a systematic hand exam?

—A systematic hand exam ensures a thorough evaluation of joint function, nerve integrity, and other factors, leading to accurate diagnoses and appropriate treatment.

Why is it important to assess the joints above and below the affected area during a hand exam?

—Assessing the joints above and below helps identify any related injuries or compensatory mechanisms, providing a comprehensive view of hand function.

How can I remember the functions of the median nerve?

—Think of the median nerve as the 'tea-drinking' nerve, responsible for opposition, flexion at the wrist and elbow, and pronation.

What does the radial nerve control in the hand?

—The radial nerve controls the extensor mechanism of the wrist, allowing for actions such as extension and abduction.

What are the key muscles involved in hand function?

—The flexor digitorum profundus and superficialis muscles play a crucial role in finger flexion and grip strength, making them essential to evaluate and diagnose any hand injuries.
