Posterior transarticular screw fixation C1-2 with the Magerl technique is a challenging procedure for stabilization of atlantoaxial instabilities. Although its high primary stability favoured it to sublaminar wire-based techniques, the close merging of the vertebral artery (VA) and its violation during screw passage inside the axis emphasizes its potential(More)
Carpal tunnel syndrome is the term given to compression neuropathy of the median nerve in the carpal tunnel. It is the most common pressure-induced peripheral nerve lesion. It is typically associated with numbness of the index, long and ring fingers, and nocturnal brachialgia. The diagnosis is supported by the typical clinical symptomatology and the(More)
Non-union of the capitate is rare. So far, six cases of non-union have been reported. The authors add a new case report, involving a 29-year old tobacco worker with a typical history. The length of the capitate was restored by corticocancellous bone grafting. The mechanism by which non-union occurs is discussed, showing that the uninjured palmar V ligament(More)
Multiple fractures of the axis are rare and present challenging patterns of instability in cervical spine surgery. Once a surgeon is faced with a combination of fractures in the axis vertebra, including stable and unstable components, a sound treatment concept must be worked out to achieve primary stability, early mobilization, and superior outcome.
