Q 66.2 Congenital reduced foot deformity.
Symptoms of congenital adducted foot deformity
Congenital adducted foot deformity is characterized by adduction and supination of the forefoot along the Lisfranc joint line, valgus position of the hindfoot, subluxation or dislocation of the cuneiform bones, pronounced deformation of the metatarsal bones, atypical attachment of the anterior tibialis muscle. According to the Turner Institute, it occurs in 8% of congenital foot deformities. Two forms of congenital adducted foot deformity are distinguished: typical and atypical. According to the severity of the course, mild, moderate and severe are distinguished.
Treatment of congenital adducted foot deformity
Conservative treatment
Treatment of this deformation should be started early, with staged plaster corrections. The total treatment period for mild deformation is 2-3 months, for moderate severity - up to six months.
Surgical treatment
If conservative treatment does not produce results, surgical treatment should be performed starting from the age of 1 year. Up to the age of 10 years, the following procedures are performed: dissection of the muscle that abducts the big toe, the capsular-ligamentous apparatus between the metatarsal and cuneiform bones of the inner part of the foot, modeling resection of the 1st and 2nd cuneiform bones, changing their position from almost horizontal to vertical, moving the attachment point of the anterior tibial muscle to the 2nd cuneiform bone with subsequent fixation with pins and a plaster cast. In older children, operations are performed on the bones of the foot and the tendon-ligamentous apparatus. Osteotomies of the 1st-5th metatarsal bones, resection of the bases of the metatarsal bones, resection of the cuboid and cuneiform bones, etc. are performed. Correction of hallux valgus is performed in the second stage at a later age.
