We report a new classification of intercostal nerve transfer. The specific application in brachial plexus reconstruction is described. This method was applied in intercostal nerve transfer to the musculocutaneous nerve in 15 patients. ⋯ In type 2, "MIXED to MIXED" transfer, based on neural cartography, the main motor branch and its sensitive accessory anterior branches are connected to the musculocutaneous nerve trunk, in attempt to connect the motor fascicules together at the center and also the sensory fascicules together, at the circumference. In type 3, "MOTOR to MOTOR" transfer, the intercostal main motor branch is connected to the musculocutaneous motor branch directly destined to the biceps brachialis. The aim of this work is to evaluate the results between different series.

Comparative Study[Long term results of the surgical treatment of bicondylar fractures of the distal humerus extremity in adults].
In intra-articular fractures of the distal humerus, full functional recovery is difficult to obtain. An osteosynthesis by plate is the treatment of choice, but location and type of plate always remain open for debate. We present a consecutive series of intra-articular fractures of the distal humerus treated by osteosynthesis. The aim of the study is to determine and to compare the results of various types of osteosynthesis. ⋯ This surgery is difficult and entails complications. The dismantling of the synthesis always gives poor results particularly if it is succeeded by an immobilization in plaster. The poor reduction, origin of arthrosis, of loss of bony substance and of calcifications worsen the functional prognosis. Last but not least, a good result can be obtained in the most of the cases however the types of fractures.

[Biomechanical evaluation of osteosynthesis with cannulated screws for Ponteau-Colles fractures in a bird model].
The use of cannulated screw without protrusive head in Colles fractures could avoid some of the drawbacks of conventional pinning. In order to compare the mechanical resistance of Kirshner wires versus cannulated screws we designed a animal model of Colles fractures and tested three types of osteosynthesis: A: K-wires, B: Herbert cannulated screw, C: specific cannulated screws. ⋯ The use of an animal model makes the experimentation easier and the sampling more homogeneous. In this model, resistance to compression of the cannulated screw was better than K-wires and the specific cannulated screw better than Herbert screw. Therefore clinical trial of osteosynthesis with cannulated screw in Colles fracture could be considered.
