Between 1977 and 2009, a total of 22 children (31 feet) underwent this procedure. In 15 children (48%) the CCF was isolated and in the remainder it was not (seven with arthrogryposis, two with spinal dysraphism, one with a polymalformative syndrome and six with an undefined neurological disorder). <\/jats:p><jats:p> Pre-operatively, the mean tibiotalar angle was 150.2\u00b0 (106\u00b0 to 175\u00b0) and the mean calcaneal pitch angle was -19.3\u00b0 (-72\u00b0 to 4\u00b0). The procedure included talonavicular and calcaneocuboid joint capsulotomies, lengthening of tendons of tibialis anterior and the extensors of the toes, allowing reduction of the midtarsal joints. Lengthening of the Achilles tendon was necessary in 23 feet (74%). <\/jats:p><jats:p> The mean follow-up was 11 years (2 to 21). The results, as assessed by the Adelaar score, were good in 24 feet (77.4%), fair in six (19.3%) and poor in one foot (3.3%), with no difference between those with isolated CCF and those without. The mean American Orthopaedic Foot and Ankle Society midfoot score was 89.9 (54 to 100) and 77.8 (36 to 93) for those with isolated CCF and those without, respectively. At the final follow-up, the mean tibiotalar (120\u00b0; 90 to 152) and calcaneal pitch angles (4\u00b0; -13 to 22) had improved significantly (p &lt; 0.0001). Dislocation of the talonavicular and calcaneocuboid joints was completely reduced in 22 (70.9%) and 29 (93.6%) of feet, respectively. Three children (five feet) underwent further surgery at a mean of 8.5 years post-operatively, three with pes planovalgus and two in whom the deformity had been undercorrected. No child developed avascular necrosis of the talus. <\/jats:p><jats:p> Midtarsal joint release and open reduction is a satisfactory procedure, which may provide better results than peritalar release. Complications include the development of pes planovalgus and persistent dorsal subluxation of the talonavicular joint. <\/jats:p><jats:p> Cite this article: Bone Joint J 2014;96-B:837\u201344. <\/jats:p>","DOI":"10.1302\/0301-620x.96b6.32313","type":"journal-article","created":{"date-parts":[[2014,6,2]],"date-time":"2014-06-02T12:31:41Z","timestamp":1401712301000},"page":"837-844","update-policy":"https:\/\/doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":22,"title":["The surgical treatment of children with congenital convex foot (vertical talus)"],"prefix":"10.1302","volume":"96-B","author":[{"given":"M.","family":"Ramanoudjame","sequence":"first","affiliation":[{"name":"Necker Enfants-Malades Hospital, 149\rrue de S\u00e8vres 75015 Paris; Paris Descartes University, Assistance\rPublique des H\u00f4pitaux de Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Loriaut","sequence":"additional","affiliation":[{"name":"Necker Enfants-Malades Hospital, 149\rrue de S\u00e8vres 75015 Paris; Paris Descartes University, Assistance\rPublique des H\u00f4pitaux de Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Seringe","sequence":"additional","affiliation":[{"name":"Cochin Hospital, 27\rrue du Faubourg Saint-Jacques 75014 Paris; Paris Descartes University, Assistance\rPublique des H\u00f4pitaux de Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Glorion","sequence":"additional","affiliation":[{"name":"Necker Enfants-Malades Hospital, 149\rrue de S\u00e8vres 75015 Paris; Paris Descartes University, Assistance\rPublique des H\u00f4pitaux de Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Wicart","sequence":"additional","affiliation":[{"name":"Necker Enfants-Malades Hospital, 149\rrue de S\u00e8vres 75015 Paris; Paris Descartes University, Assistance\rPublique des H\u00f4pitaux de Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"42","reference":[{"key":"r1","first-page":"79","volume":"21","author":"Lamy L","year":"1939","journal-title":"J Bone Joint Surg [Am]"},{"key":"r2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199512000-00019"},{"key":"r3","first-page":"128","volume":"139","author":"Ogata K","year":"1979","journal-title":"Clin Orthop Relat Res"},{"key":"r4","first-page":"427","volume":"36","author":"Stern HJ","year":"1989","journal-title":"Clin Genet"},{"key":"r5","first-page":"25","volume":"22","author":"Dobbs MB","year":"2002","journal-title":"Iowa Orthop"},{"key":"r6","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-198307000-00007"},{"key":"r7","doi-asserted-by":"publisher","DOI":"10.1177\/107110078700700602"},{"key":"r8","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-198405000-00007"},{"key":"r9","doi-asserted-by":"crossref","first-page":"207","DOI":"10.1016\/S0030-5898(20)30891-9","volume":"9","author":"Campos Da Paz A","year":"1978","journal-title":"Orthop Clin North Am"},{"key":"r10","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.55B3.566"},{"key":"r11","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.61B4.387799"},{"key":"r12","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-199901000-00010"},{"key":"r13","doi-asserted-by":"publisher","DOI":"10.1097\/01202412-199504020-00010"},{"key":"r14","first-page":"261","volume":"11","author":"Rigault P","year":"1970","journal-title":"Ann Chir Inf"},{"key":"r15","first-page":"234","volume":"76","author":"Seringe R","year":"1990","journal-title":"Rev Chir Orthop Reparatrice Appar Mot"},{"key":"r16","first-page":"527","volume":"81","author":"Daumas L","year":"1995","journal-title":"Rev Chir Orthop Reparatrice Appar Mot"},{"key":"r17","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-198707000-00005"},{"key":"r18","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-200103000-00015"},{"key":"r19","first-page":"282","volume":"54","author":"Rombouts JJ","year":"1988","journal-title":"Acta Orthop Belg"},{"key":"r20","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.49B4.634"},{"key":"r21","doi-asserted-by":"publisher","DOI":"10.1097\/01.bpo.0000173244.74065.e4"},{"key":"r22","unstructured":"M\u00e9ary R.
