Removable flexible orthosis for middle foot damage

摘要

The invention concerns a removable flexible orthosis for middle foot damage comprising three bands in all (the metatarsophalangeal band, the tarsal band, the maleollar band) and two straps (a traction strap and a lateral return strap which can be symmetrical). The metatarsophalangeal band (2, 15) is adapted to be fixed on the forefoot and extends transversely, from the foot to the heads of the first and fifth metatarsi and, longitudinally, from the rear of the root of the toes towards the shaft of the metatarsi. The traction strap (4, 16) comprises at least one end fixed or capable of being fixed on the first metatarsophalangeal band (2, 15), said traction strap extending between said first band (2, 15) and the portion of the orthosis designed to be applied on the rear of the foot. Preferably, the traction strap is shaped like a metatarso-calcaneo-metatarsal stirrup, its two ends being fixed on the postero-external and postero-internal edges on the first metatarsophalangeal band.
