A 30-year-old rock climber presents with significant pain and loss of function in the fingers after a fall. Imaging studies suggest a partial tear of the A2 pulley associated with a flexor tendon injury. During the assessment, the clinician evaluates the impact of this injury on the biomechanical function of the finger flexors. How does an injury to the A2 pulley specifically affect the biomechanics of the flexor tendons and grip strength?
