Anatomical orientation by 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 mainly affected finger (here little finger). Brunner's incision in the area of the proximal and middle phalanx. Additional diverging oblique incision over a secondary cord from the distal palmar crease to the proximal phalangeal crease of the ring finger.
Sharp transection of the skin.
Guiding structures
- Distal palmar crease
- Proximal phalangeal crease
- Proximal interphalangeal crease
- Interthenar crease
- Main and secondary cord
Note
To avoid future scar contractures, the incision should be planned so that the scar does not lie directly over a flexion crease.
