Ideal

• Elbow joint is in neutral (0° of flexion)
• Forearm deviates from arm at an angle of up to 15° in women and up to 10° in man

You See

• Forearm is held in flexion
• Forearm deviates from arm at an angle of greater than 15° in women and greater than 10° in men

Likely Cause

• Short elbow flexors, especially biceps brachii if scapula is tilted anteriorly and on passively extending the elbow, the anterior tilt of the scapula increases
• Cubitus valgus for forearm deviation
