Anatomical orientation through palpation and marking of anatomical landmarks:
Zigzag incision from the distal interthenar crease over the distal palmar crease to the proximal phalangeal crease of the primarily affected finger (here, the little finger). Brunner's incision in the area of the proximal and middle phalanx. Additional diverging oblique incision over an accessory cord from the distal palmar crease to the proximal phalangeal crease of the ring finger.
Sharp division of the skin.
Guiding structures
- Distal palmar crease
- Proximal phalangeal crease
- Middle joint crease
- Interthenar crease
- Main and accessory cord
Remark
To prevent future scar contractures, the incision should be planned so that the scar does not lie directly over a flexion crease.
