old unreduced elbow fracture and fracture dislocation: treatment with open reduction and hinge external fixation

background: old unreduced elbow dislocation and fracture-dislocation, although rare, are one of the challenges in orthopedic surgery. the application of the hinged elbow external fixator can confer early range of motion after open reduction and reconstruction in spite of severe soft tissue and bony injury.objectives: this study presents our results of open reduction and reconstruction in old simple elbow dislocation and old elbow fracture-dislocation.patients and methods: in 12 patients with old elbow dislocation, open reduction and bone and soft tissue reconstruction was done and early postoperative range of motion was begun with the aid of hinged elbow external fixators.results: the mean elbow range of motion at the final follow-up was 98 degrees (sd = 10). according to the mayo elbow performance index score, 6 patients achieved excellent results and 2 other had good results with a mean value of 92 (sd = 8).conclusions: we recommend hinged elbow external fixation in old elbow dislocation for early range of motion and maintenance of concentric reduction with acceptable results.
