Aim. The aim of the study was to evaluate the results of percutaneous fixation of scaphoid fractures using Twin-Fix® canulated screw.
Methods. From 2000 to 2006 30 patients were surgically treated, 25 presented acute unstable fractures (tipe B) and 5 showed pseudo-arthrosis according to Herbert’s and D’Arien-zo’s classification. The duration of postoperative immobilization, necessity to initiate assisted rehabilitation, functional outcome were evaluated using the Mayo Wrist Score (MWS), time of return to work and patient satisfaction.
Results. All patients acquired radiographic union in an average of 8.6 weeks. The MWS averaged 98.4.The functional result was ranked as excellent in all 30 patients. All returned to work or the preinjury level of activity, and were satisfied with the surgical outcome.
Conclusion. Percutaneous fixation by Twin-Fix® cannulated screw of acute unstable fractures and of pseudoarthrosis (not requiring the use of bone graft) has proved safe and effective procedure, allowing a rapid healing and a quick return to normal working and sport activities with patient’s high satisfaction.
