Summary
Extensor mechanism of the finger. In the drawing on the left the common extensor tendon is shown in red. It attaches to the proximal phalanx via bands and extends the MCP joint. In the center figure, the trifurcation is shown. the central slip, shown in sky blue, inserts on the middle phalanx and extends the PIP joint. The lateral bands are shown in blue. In the right-most drawing, the lateral bands are shown joined by the tendons of the interosseous and lumbrical muscles and inserting on the distal phalanx, thereby extending the DIP.
