Ana<strong>to</strong>mic, con<strong>to</strong>ured joint resection <strong>of</strong><strong>the</strong> head <strong>of</strong> <strong>the</strong> proximal phalanx.Figure 10B. This technique minimizes boneshortening <strong>and</strong> increases <strong>the</strong> surface area available <strong>to</strong>contact <strong>the</strong> middle phalanx.Figure 11A.
