Internal fixation of displaced middle third fractures of clavicle with precontoured locking plate.

Abstract

The traditional method of treating displaced mid clavicular fractures with conservative methods gives poor results. When there is displacement more than 2 cm and shortening, internal fixation of the clavicle, when performed properly, gives better results. We reviewed the results of 20 cases of middle third clavicle fractures (Edinburg type 2B) with displacement more than 2 cm which were treated with open reduction and internal fixation with precontoured locking plate and screws. In all the fractures radiological union was evident by 10-16 weeks. None of the patients had complications like malunion, nonunion, deep infections, and implant failure and neurovascular damage. There was no problem with hardware and implant removal was not done. The average constant score was 95.45. All the patients were satisfied with the cosmetic appearance of surgical scar. Precontoured locking plate fixation gives excellent results, facilitates early return to function, results in better cosmesis and avoids complications of conservative methods like nonunion, malunion and also implant removal is not necessary.
