Forty-three patients with comminuted Craig type Ⅱand Ⅴ distal clavicle fractures were treated with clavicular hook locking plate and Kirschner wire from July 2013 to January 2015 in Tengzhou Central People's Hospital.Patients were followed up for 12-20 months with an average of 18 months.All fractures were clinically healed .In the 3 and 6 months after the operation, the Constant-Murley function score and the visual analogue score ( VAS) of the quality of life satisfaction were improved compared with those before operation (75.1 ±1.4 and 85.6 ±1.3 vs.44.3 ±1.8; 7.02 ±0.67 and 8.16 ±0.57 vs. 2.54 ±0.67, all P ＜0.05).There were no fracture delayed healing, nonunion, plate fracture and clavicular re-fracture among all patients .It is suggested that the curative effect of the clavicular hook locking plate combined with Kirschner wire is satisfactory and the bone healing rate is high for comminuted Craig type Ⅱ and Ⅴ type distal clavicle fractures.
