Clavicle reductor homeopathic traction and minimally invasive plate osteosynthesis for treatment of displaced midshaft clavicular fractures

Abstract

Objective To investigate the effect of displaced midshaft clavicular fractures treated by clavicle reductor homeopathic traction and minimally invasive plate osteosynthesis (MIPO). Methods A prospective case control study was made on 84 cases of unilateral displaced midshaft clavicular fractures admitted from January 2014 to June 2014. According to the random number table, the patients were allocated to experiment group (43 cases) and control group (41 cases). Subjects in experiment group were treated by homeopathic traction using the self-designed clavicle reductor and MIPO, including 36 male and seven female cases aged 32(24.0, 47.0) years. In contrast, control group were treated by traditional open reduction and internal fixation, including 37 male and four female cases aged 32(26.0, 44. 5)years. According to the OTA classification, 22 cases were type 15-B1, 13 type 15-B2 and eight type 15-B3 in experiment group, while 22 type 15-B1, 12 type 15-B2 and seven 15-B3 in control group. Operation duration, fluoroscopy time, complications and bone healing was recorded. Constant-Murley score was employed to test the functional outcomes. Results Operation duration was 45(36.0, 54.0)min in experiment group and 49 (40.0, 67.5)min in control group (P 0.05). Conclusion MIPO technique assisted with clavicle reductor homeopathic traction in treatment of displaced midshaft clavicular fractures has similar efficacy with the traditional open reduction and internal fixation, but the former technique is associated with relatively shorter operation time and smaller wound.
