title: Carpal scaphoid non-union treatment: a retrospective trial comparing simple retrograde percutaneous screw fixation versus percutaneous screw fixation plus pulsed electromagnetic fields (Physiostim®).
abstract: BACKGROUND
  The purpose of this retrospective comparative study was to assess whether a complementary treatment by pulsed electromagnetic field could increase the bone-healing rate of scaphoid non-union without SNAC (scaphoid non-union advanced collapse) treated by retrograde percutaneous screw fixation.
  
  
  METHODS
  Eighteen patients with scaphoid non-union were included in this retrospective study. The group 1 was made of nine cases (seven stage IIA and two stage IIB) of scaphoid non-union treated by retrograde percutaneous screw fixation and pulsed electromagnetic fields (Physiostim®). The group 2 was made of nine cases (six stage IIA and three stage IIB) treated by simple retrograde percutaneous screw fixation.
  
  
  RESULTS
  With a 10-month follow-up in group 1 and a 9.5-month follow-up in group 2, there were three cases of non-union in group 1 and two cases in group 2. Regarding the type of non-union, there was one case among the stage IIB and four cases among the stage IIA.
  
  
  CONCLUSIONS
  The results of the study did not show any interest in the use of pulsed electromagnetic field for the treatment of carpal scaphoid non-union. They should be dropped.
