Surgery

• Dorsal approach
  The skin is incised on the dorsum of the proximal and middle phalanges, and the extensor tendon is split.
• Removal of articular cartilage
  Using a narrow Langenbeck retractor to gently separate the articular surfaces, the cartilage is removed by currettage.

  

• Plate placement
  The narrow 5 hole DCP is placed dorsolaterally to prevent interference with the extensor process of the distal phalanx.
