Minimally invasive treatment of clavicular fractures with cannulated screw.

Abstract

Objective: To evaluate minimally invasive treatment of clavicular fractures with cannulated screw.

Methods: Data of 65 patients who had undergone minimally invasive treatment with cannulated screws for clavicular fractures from April 2009 to October 2010 were retrospectively analyzed and compared with those of 65 patients with clavicular fractures who had been treated by the same surgeons with plates. In the study group, there were 41 males and 24 females, aged from 19-67 years (mean, 35.8 years). According to Craig's classification, there were 29 group 1 and 36 of group 2-II. Neer scores were used to evaluate shoulder function and radiographs to assess fracture union.

Results: The incision length was 4-5 cm in the cannulated screw group (CSG) and 10-11 cm in the reconstructive plate group (RPG). Radiographs showed bone union was achieved in both groups, the bone healing time being 13.2 ± 6.9 weeks in the CSG and 16.3 ± 8.7 weeks in the RPG. All patients were followed up for 6 to 20 months (average, 10.6 months). The average Neer score was 96.6 ± 3.4 in the CSG and 94.2 ± 5.8 in the RPG. In the CSG, screw loosening occurred in five, and fracture displacement in three. There was a significant difference in fracture healing time between two groups but not in Neer score.

Conclusion: Minimally invasive treatment of clavicular fractures with cannulated screws has the advantages of minimal invasion, short bone healing time, good clinical outcomes, and being relatively inexpensive.
