• DSTP = distal soft-tissue procedure, the adductor hallucis tendon is detached
from the fibular sesamoid and the proximal phalanx, the deep transverse
metatarsal ligament is divised, the lateral aspect of the first
metatarsophanlangeal joint capsule is released with multiple stab incisions
• P = phalanx
•IM = intermetartasal
• M/MT = metatarsal
• MTP = metatarsophalangeal joint
• Claw toe = dorsiflexion contracture at the metatarsophalangeal joint
•Mallet toe = flexion deformity only at the distal interphalangeal joint, with normalproximal interphalangeal and metatarsophalangeal joints, distal hammer toe
deformity
• Proximal hammer toe deformity = only the proximal interphalangeal joint is
affected

•Keller-Leliévre-Villadot procedure = resection of the proximal phalanx ofthe toe (F1) and sesamoids realignment according to Leliévre´s
“cerclage fibreux” and a reefing point suture in the flexor tendon (Viladot)
• Exostectomy = resection of the pseudoexostosis at the first metatarsal
head
• Chevron procedure = distal first metatarsal osteotomy
• Scarf osteotomy = diaphyseal osteotomy, metatarsal Z-sloped osteotomy
of the first metatarsal• Akin procedure = proximal phalangeal osteotomy (P1)
• Weil procedure = distal horizontal metatarsal osteotomy, when the
metatarsal head is to be preserved

Surgical treatment of hallux valgus
•Indications for surgical treatment: – Simptoms present - Painful joint ROM
– Activity or lifestyle restrictions
– Important or fast evolution joint deformity
– Footwear painful or uncomfortable
– Associated foot disorders
And...
– Shoe modification fails
Note: Cosmetic concerns are not a surgery indication!
