Syndesmosis Procedure
Syndesmosis procedure is a surgery name given by Dr. Daniel Y. Wu of Hong Kong for an unconventional hallux valgus (bunion) deformitysurgery. This surgical technique was developed from a non-bone-breaking procedure that was practiced by Dr. Michael Harrison of Canada in the early 1980’s and it was similar to what had been described by Pagella P and Pierleon G P of Italy.
Syndesmosis procedure was such named to reflect the essence of its surgical principle and differs from the original technique by taking one step further in preserving not only the innocent and normal first metatarsal and proximal phalangeal bones of bunion feet but also their adductor hallucis tendon and fibula sesamoid from being sacrificed without any proven justifications.
Hallux valgus deformity of the foot is more accurately and formally described by orthopaedic surgeons as hallux valgus deformity complex because it is often made up of not only hallux valgus and bunion but also several other anatomical derangements such asmetatarsus primus varus, sesamoid subluxation/dislocation, clawed/hammer toes, collapsed arches, calluses etc. These are all secondary derangementsexcept the probable primary deformity,metatarsus primus varus. Indeed, metatarsus primus varus correction hasalways been the primary objective of most bunion surgeries. Metatarsus primus varus deformity is basically de-stabilization and dis-placement of the first metatarsal bone. Bunion surgery istore-align and re-stabilize thisunstable and displaced normalbone. Syndesmosis procedure specifically addresses the destabilization problem of first metatarsal bone by creating a syndesmosis-like bonding to stabilize first metatarsal to the second one which happens to be the most stable of all five metatarsal bones in the forefoot.
By being able to re-align and re-stabilize the unstable and displaced first metatarsal bone without having to break any bones, it is a less traumatic andmuch safer bunion surgery.
