Distal tibiofibular radiological overlap

چکیده
OBJECTIVES Overlap between the distal tibia and fibula has always been quoted to be positive. If the value is not positive then an injury to the syndesmosis is thought to exist. Our null hypothesis is that it is a normal variant in the adult population. METHODS We looked at axial CT scans of the ankle in 325 patients for the presence of overlap between the distal tibia and fibula. Where we thought this was possible we reconstructed the images to represent a plain film radiograph which we were able to rotate and view in multiple planes to confirm the assessment. RESULTS The scans were taken for reasons other than pathology of the ankle. We found there was no overlap in four patients. These patients were then questioned about previous injury, trauma, surgery or pain, in order to exclude underlying pathology. CONCLUSION We concluded that no overlap between the tibia and fibula may exist in the population, albeit in a very small proportion.

A reliable radiographic measurement for evaluation of normal distal tibiofibular syndesmosis: a multi-detector computed tomography study in adults
BACKGROUND Syndesmotic injury may be difficult to diagnose, and radiological evaluation is very important. The purpose of this study was to offer a series of reliable and repeatable normal tibiofibular syndesmosis parameters in diagnosing injuries of the syndesmosis. METHODS Multi-detector computed tomography (MDCT) and radiographs of the distal tibiofibular syndesmosis in 484 cases were retr...
متن کاملInjuries to the tibiofibular syndesmosis.
The management of injury to the distal tibiofibular syndesmosis remains controversial in the treatment of ankle fractures. Operative fixation usually involves the insertion of a metallic diastasis screw. There are a variety of options for the position and characterisation of the screw, the type of cortical fixation, and whether the screw should be removed prior to weight-bearing. This paper rev...
متن کاملCongenital distal tibiofibular synostosis
Congenital distal tibiofibular synostosis is a very rare anomaly. The cases of congenital tibiofibular synostosis reported in the literature so far have been confined to the proximal tibiofibular joint. We present an unusual case of tibiofibular synostosis that involves the distal part of the tibia and fibula based on characteristic X-ray, CT, and MRI findings.

متن کاملDistal Tibiofibular Syndesmosis: Anatomy, Biomechanics, Injury and Management
A stable and precise articulation of the distal tibiofibular syndesmosis is essential for normal motion of the ankle joint. Injury to the syndesmosis occurs through rupture or bony avulsion of the syndesmotic ligament complex. External rotation of the talus has been identified as the major mechanism of syndesmotic injury. None of the syndesmotic stress tests was sensitive or specific; therefore...
