Indicated in minor deformities that can be corrected passively in relatively young patients with no other toe deformities or degenerative joint lesions. Essential surgical procedures: Italic S shaped dorsomedial incision, isolation of the dorsomedial and dorsolateral vessels and nerves, distal isolation of the abductor, Silver type preparation of the capsular flap, extensive lateral arthrotomy, section of the phalangeal head of the abductor, dorsalisation of the abductor tendon to which the medial capsular flap is anchored. 1) Transplant of flexor longus pro flexor brevis: indicated in hallux insufficiency after the Keller operation. Lysis of the nearthrodesis in 10-15° flexion of the interphalangeal synthesised with a staple or screw; plantodorsal transosseous transplant of the flexor longus to the basal phalanx in flexion. 2) Transplant of the flexor superficialis pro interossei: indicated in unstructured functional claw of the toes. Multiple V-shaped transversal incision onto the digitoplantar flexion fold. After incision of the flexor sheath the V of the flexor superficialis is isolated and detached distally: both branches are transposed dorsally under the periosteum to the two sites of the diaphysis of the proximal phalanx. This is followed by expansion of the interossei and suturing to the contralateral below the extensor tendon.
