Modified pullout wire technique for extensor tendon insertion injuries

Abstract

Objective To explore the modified pullout wire technique for treatment extensor tendon insertion injuries and discuss ways to decrease complications.Methods From May 2006 to June 2012,46 cases 47 fingers of extensor tendon insertion injuries were treated with modified pullout wire technique.A Kirschner wire (K-wire) was longitudinally inserted into the distal phalanx without going through the DIP joint.The end of the K-wire was bent to form a Z shaped hook.A stainless steel wire was threaded through the extensor tendon about 8 to 10 mm to the insertion in a Kessler suture fashion and then went through the phalanx base on both sides to be fastened on the K-wire hook.Results All cases were follow-up for 8 to 33 months postoperatively.DIP joint range of motion was between 50° and 70°.No complications were observed.According to Dargan scales,the result was excellent in 42 cases 43 fingers and good in 4 cases 4 fingers,with the excellent and good rate being 100％.Conclusion The modified pullout wire technique leads to satisfactory results and should be a predictable,low-morbidity,low-cost treatment,safe and simple method for treatment of extensor tendon insertion injuries.
