Purpose: To report the treatment results of anatomical reduction of all fracture fragments and internal fixation using an inter-fragmentary screw and plate in displaced mid-shaft clavicle fracture with comminution.
Materials and Methods: Between June 2005 and August 2011, 13 consecutive displaced clavicle fractures with comminution (Edinburgh classification IIB2) treated by anatomic reduction and internal fixation using inter-fragmentary screw and plate were retrospectively evaluated. There were 11 male and 2 female patients with a mean age of 37.4 years (15∼55 years). The right clavicle was injured in 4 patients and the dominant arm was involved in 46%. The mean duration from trauma to surgery was 7.0 days. The cause of injury was a traffic accident in three, a fall in two, and sports activity or direct injury in eight patients. All of the fracture pieces were anatomically reduced and fixed with inter-fragmentary screws. An additional plate was applied to maintain and reinforce the reduction of the fracture. Radiographic assessments for the numbers of fragments and the amount of shortening and displacement were performed. To verify the fracture healing and determine the time from fracture surgery to union and complications, all of the radiographs taken after surgery were evaluated.
Results: The number of fragments was 2 in 7 cases, 3 in 5 cases, and 6 in one case. The mean shortening of the clavicle was 1.1 cm (0.3∼2.1 cm) and mean displacement between the main fragments was 2.6 cm (1.3∼4.5 cm). The mean duration of follow-up was 16.5 months (8∼26 months). Radiographic union was achieved in all patients with a mean time to union of 10.8 weeks (8∼14 weeks). There were no complications including metal failure, nonunion, or infection.
Conclusion: Anatomical reduction of all the fracture fragments and fixation using inter-fragmentary screws in addition to the usual plate fixation showed good fracture healing in displaced clavicle fracture with comminution.
