The Case Control Study Of Hook Plate In Treatment Of Neer Ⅱ Distal Clavicle Fracture Betweenthird Hospital Of Hebei Medical University And Mass General Hosptial

Objective: Clavicle fracture is a common fracture,accounting for about 2.6% to 4% of fractures.According to the fracture location,the clavicle fracture is divided into proximal,middle and distal fractures.The distal clavicle is one of the important joints between the sacrum of the upper limb and the trunk bone.Its anatomical structure is complicated.After the distal clavicle is fractured,the distal end of the fracture line is displaced downward due to the pull of the upper limb gravity,deltoid and trapezius.Therefore,the nonunion rate of distal clavicle fractures is extremely high.This project intends to guide the treatment of distal clavicle fractures by studying the clinical effects of hook plates at home and abroad in treating Neer II distal clavicle fractures.Methods: According to the inclusion criteria,a retrospective analysis of 42 patients with type Neer II distal clavicle fractures treated and treated at the Trauma Emergency Center of the Third Hospital of Hebei Medical University from January 1,2017 to May 30,2018,including 30 males There were 12 females,aged 14-63 years,with an average age of 42.7 years,27 Neer type IIA patients and 15 Neer type IIB patients;34 patients with distal Neer type II clavicle fractures were selected from the Department of Orthopaedics,Massachusetts General Hospital,including 23 males.There were 11 females,aged 17-63 years,with an average age of 41.4 years,24 cases of Neer type IIA and 10 cases of Neer type IIB.Collect the general clinical data,fracture healing rate,postoperative complications,removal rate of internal objects,and postoperative VAS scores.A retrospective study,combined with statistical software,was used to analyze the clinical effect of hook plate in the treatment of Neer II distal clavicle fracture.Results: By statistical comparison,the differences in basic information such as age,sex,weight,cause of injury,and fracture type between the two groups of patients were not statistically significant(P﹥0.05),and they were comparable.None of the patients had incision infection,fracture failure,or rupture of the hook plate.By statistical analysis,there were no significant differences in fracture healing rates,VAS scores 4 weeks after hook plate placement,VAS scores before hook plate removal,and VAS scores 4 weeks after hook plate removal.The removal rate of hook plate of patients in the THH was 71.4%,which was significantly lower than that of the MGH.The removal rate was 91.8%,and the difference was statistically significant.The removal rate of hook plate and the VAS score before removal of the hook plate were significantly higher than the VAS score of 4 weeks after the removal of hook plate.The difference was statistically significant,that is,the pain was significantly relieved after the removal of the hook plate.The difference was statistically significant.Conclusions: The distal clavicle hook plate can achieve satisfactory clinical results and fewer complications in the treatment of Neer type Ⅱ distal clavicle fractures.In addition,removing the hook plate as early as possible after fracture healing can significantly reduce the VAS score and relieve shoulder pain and discomfort in patients.
