Abstract | BACKGROUND: METHODS: The records of seven children (four boys and three girls aged 6 months - 11 years) of different ethnic origins have been included in this study. The constellation of specific craniofacial dysmorphic features, spine malformation complex, and appendicular skeletal abnormalities in addition to camptodactyly, talipes equinovarus and rocker-bottom feet were a cluster of malformation complex encountered in our patients. Via comprehensive clinical and imaging study (3D reconstruction CT scan), definite diagnosis of Escobar Syndrome has been approached. RESULTS: The clinical and imaging phenotype was the key factor towards etiological understanding, treatment and genotype confirmation. We identified compound heterozygous mutations (c.459dupA [p.Val154Serfs*24] and c.794T>G [p.Leu265Serfs*24] of the CHRNG gene in four patients. Bilateral flexion contractures of the knees have been treated by using Iliazarov external fixator. Simultaneous corrections of scoliosis have been achieved by applying either dual traditional growing rods or single growing rods. CONCLUSIONS: The clinical and radiological phenotypic characterizations are the fundamental tool in differentiating Escobar from other forms of multiple contractures. The aim of this study are three folds, firstly to demonstrate the importance of detecting the etiological understanding in children presented with multiple contractures, secondly to refute the general conception among the vast majority of pediatricians and orthopedic surgeons that arthrogryposis multiplex is a diagnostic entity. And thirdly, we were able to detect severe spine deformity via 3D reconstruction CT scan, namely unsegmented posterior spinal bar.
