Post-traumatic radioulnar synostosis is a rare complication of forearm fracture. Resulting in loss of forearm axial rotation, it is functionally very disabling. The surgical indication, timing of operation, surgical technique, interest and type of adjuvant treatment are all issues with which physicians managing radioulnar synostosis must deal. No therapeutic consensus yet exists, but a wide var...

STUDY DESIGN A prospective radiographic study of cervical spine with congenital monosegment fusion. PURPOSE To evaluate the effect of cervical synostosis on adjacent segments and the vertebral morphology. OVERVIEW OF LITERATURE There are numerous clinical studies of adjacent segment disease (ASD) after monosegment surgical fusion. However, there was no report on ASD in the cervical spine wi...

Most cases of Apert syndrome are due to S252W or P253R mutations in the fibroblast growth factor receptor 2 (FGFR2) gene. Differences in the effects of S252W and P253R mutations on the clinical features of Apert syndrome have been studied, but little is known about the type of FGFR2 mutation in Apert syndrome with humeroradial synostosis. To study a correlation between the FGFR2 mutations and t...

Boundaries between cellular compartments often serve as signaling interfaces during embryogenesis. The coronal suture is a major growth center of the skull vault and develops at a boundary between cells derived from neural crest and mesodermal origin, forming the frontal and parietal bones, respectively. Premature fusion of these bones, termed coronal synostosis, is a common human developmental...

The incidence of synostosis of the proximal tibiofibular joint (TFJ) was assessed among 1029 patients examined for osteoarthritis of the knee in a 4-year period. Radiographic evidence of a synostosis of the proximal TFJ was demonstrated in 3 knees (3 patients). The synostosis appeared incidental and was not the cause of symptoms in any of them. These patients were further examined with MRI and/...
