[Treatment of scaphoid waist fractures by shape memory staples. Retrospective evaluation on 60 cases].
In carpal scaphoid fractures, treatment with screws is considered the gold standard: ostheosynthesis with mini-staples is not the usual choice of treatment. The authors report a study on fractures of the middle third of the scaphoid treated by mini shape memory staples, in order to test the quality of reduction and ostheosynthesis, functional results, time of union and complications. ⋯ Our results show the safety and the practicality of ostheosynthesis with mini shape memory staples in fresh unstable fractures of the middle third of the scaphoid. Stable fixation, continuous compressive force on fragments and the ability to allow early active movement, are the main advantages.

Crucifixion was developed and abolished during the roman empire. The historical and pagan works are rare, and the story of Christianity gave us the firsts elements of knowledge of this punishment. ⋯ The anatomical work of the artists was then widely used, but it is only during the twentieth century that anatomists and surgeons studied with precision the fixation of the upper limbs on the cross. Lastly the modem imagery with computerised reconstruction allowed a direct vision of the nail in the different structures of the wrist.

[Scaphoid percutaneous osteosynthesis by screw using computer assisted surgery: an experimental study].
Scaphoid fractures are sometimes difficult to diagnose and even more difficult to fix. Recent progress such as miniaturization of osteosynthesis material, adoption of the percutaneous route, and widening of the indications to include undisplaced fractures has still not abolished complications. In this context, computer assisted surgery (CAS) may be useful and deserves further study. ⋯ Its limits are of a geometrical nature "two images available in two planes", data processing "non-specific software dedicated", instrumental "instrument calibration, micromobility of the immobilisation device" and live surgery "no current validation on a fractured scaphoid". Meantime, the development of a percutaneous scaphoid osteosynthesis procedure by CAS can only bring advantages: reduction in the learning curve, widening of the indications, comfort in the technique, reduction in the errors of ostesynthesis and, reduction in the exposure to x-rays. In the current state of knowledge, the method would only be applicable to undisplaced fractures.
