Describe the Bunnell-Littler test
It is a test for patients with difficulty flexing the PIP joint, since it can differentiate interosseous tightness
from capsular contraction. To carry it out, ask patients to hold the MCP joint in a few degrees of extension,
and then flex their PIP joint. If unable to do so, have them place the MCP in flexion, and then reattempt PIP
flexion. Those with capsular contraction will not flex the PIP at all, whereas those with interosseous tightness
will flex it by using the second maneuver
