Clinical Study On The Effect Of Clavicular Hook Plate And Distal Clavicular Locking Plate In The Treatment Of Craig Type Ⅱ Distal Clavicle Fractures

Objective:Comparison and analysis of the clinical efficacy of clavicular hook plate and distal clavicle locking plate for the treatment of Craig type Ⅱ fracture of the distal clavicle.Method:28 cases of Craig type Ⅱ fracture of distal clavicle were treated with clavicular hook plate(13 cases)and distal clavicle locking plate(15 cases)respectively.The operation time,the amount of bleeding and the healing time of the fracture of the two groups were compared,and the difference of the curative effect between the two groups was compared with the VAS score and the shoulder joint Constant score.Results:All 28 patients were followed up in 9 months.The operative time and intraoperative blood loss of clavicular hook plate group and locking plate group were 55.8min,86.0ml and 63.8min,93.0ml respectively.There was a significant difference between the two groups(P<0.05).The fracture healing time of the clavicular hook plate group was 11.9 weeks,and the fracture healing time of the locking plate group was 12.2 weeks.There was no statistical difference between the two groups(P>0.05).According to the VAS score and Constant score of shoulder joint assessment,the group of clavicular hook plate in 1 month and 3 months,VAS scores were 3 points、0.5 points,locking plate group was 1.7 points and 0.3 points respectively,the group of clavicular hook plate in lmomth and 3 months,Constant score were 76.5 points、90.2 points,75.3 points and 90.9 points for locking plate group,which had statistical significance after 1 momth in VAS scores(P<0.05),the rest were no statistically significant difference.Conclusion:The clinical efficacy of clavicular hook plate and distal clavicle locking plate is satisfactory through the comparison of the 5 aspects mentioned above.The process of clavicular hook plate is simple and the trauma is small.Locking plate does not affect the normal physiological structure of the shoulder joints,and there is no risk of early shoulder pain.So the clinical application can be selected according to the severity and individual condition of the patient’s fracture.
