title: [Minimal invasive cannulated screw osteosynthesis of Bennett's fractures].
abstract: OBJECTIVE
  The current study presents a new technique and results of minimal invasive screw osteosynthesis in the treatment of Bennett's fractures and discusses its advantages and disadvantages.
  
  
  METHODS
  The Bennett's fragment has to be of sufficient size (at least one quarter of the articular surface) and closed reduction must be possible to achieve. Temporary fixation by K-wire is followed by minimal invasive osteosynthesis using a cannulated 3.0 mm screw in the lag screw technique.
  
  
  RESULTS
  18 patients underwent minimal screw osteosynthesis, of whom two were lost for follow-up. Average time of follow-up of the remaining 16 patients was 17.2 weeks. Fracture healing was achieved in all of the 16 patients. There were good to excellent results in 13 patients, fair results in one patient and poor results in two patients.
  
  
  CONCLUSIONS
  Good results can be achieved by minimal invasive screw osteosynthesis in the treatment of Bennett's fractures. Correct indications and minute operation technique are indispensable preconditions for this new kind of treatment.
