Randomized clinical trial on percutaneous minimally invasive osteosynthesis of fractures of the distal extremity of the radius.

Objectives: the purpose of this study was to compare the postoperative radiological and clinical outcomes with minimally invasive percutaneous osteosynthesis using three implants: volar locking plate, intramedullary nail system and nonbridging external fixator for distal radius fractures.

Methods: forty-eight patients (A group, 16; B group 16; C group 16) underwent minimally invasive percutaneous osteosynthesis of reductible and unstable displaced (Type IIB by Rayhack Classification) distal radius fractures. In B group intramedullary nail system was used, in A group the patients were treated with volar locking plate and in C group the patients were treated by nonbridging external fixator from January 2011 to December 2012.
