Congenital Diastasis of Tibio-Fibular Mortise

Abstract

1. Two cases of congenital diastasis of the inferior tibio-fibular mortise are described. 2. No previous description of this condition has been found in the literature. 3. it is suggested that the cause is osteochondrosis of the distal tibial epiphysis associated with a club foot.

Congenital diastasis of distal tibiofibular joint. A case report and treatment presentation

“…The pathogenesis of distal tibiofibular joint diastasis is not clear. Tuli [1] believed that it was due to osteochondrosis of distal tibial epiphysis. Others believed that main cause for the condition is hypoplasia of the distal part of the tibia [4,7,8].…”

“…Congenital distal tibiofibular diastasis is a rare disorder of unknown etiology, first described in 1972 [1]. Since then sparse cases of this condition have been reported in the English literature [1][2][3][4][5][6][7][8][9][10][11].…”

“…Congenital distal tibiofibular diastasis is a rare disorder of unknown etiology, first described in 1972 [1]. Since then sparse cases of this condition have been reported in the English literature [1][2][3][4][5][6][7][8][9][10][11]. Main clinical presentations are an equinovarus foot deformity, limb length discrepancy (LLD), distal tibial tapering and an absent ankle mortise [2,3].…”

Congenital Posterior Dislocation of Fibula with Pes Valgus Deformity

“…An earliest report of a child with congenital dislocation of the distal end of the fibula was reported by Chirurgia Narzadow Ruchu i Ortopedia Polaska [1] but it did not represent our case. Congenital diastasis of the inferior tibiofibular joint with equinovarus deformity of foot was first reported in 1972 by Tuli and Varma [2] in 2 cases. A rare pentad of foot and ankle deformity in 4 hyper lax children have been reported by IIyas et al [3] with a similar deformity description but our child did not have any hyperlaxicity.…”

Unclassified Cases of Tibial Hemimelia; Should We Modify the Classification Systems?

“…In either of the former classification systems, diastasis of the inferior tibio-fibular joint appears to be related to different types of tibial hemimelia [9,10]. However, congenital isolated Congenital diastasis of the inferior tibio-fibular joint also presents as a clinical problem such as talipes equinovarus, ankle diastasis, and leg-length inequality as many surgeons agree [11], despite the exact etiology is not well defined. We report two cases of tibial hemimelia with complete diastasis of the tibia and fibula with separate skin envelop for each bone, the first case has complete diastasis, while the second case has partial diastasis, where the deformity could not be classified by any of the above systems and hadn't been reported before.…”
