Rationale for change
Per Amboss, recurrent branch injury results in loss of thumb flexion, opposition, and abduction without sensory or other motor deficits. They write that median claw is the result of palsy of the lumbricals, which as previously stated, are not affected by a recurrent branch injury. Therefore, median claw is NOT seen.
Ape hand, on the other hand, which is due to inability to opposite or abduct thumb, is affected by a recurrent branch injury.
