Clinical Analysis Of Modified Anterior Elbow Small Incision Approach For The Treatment Of Distal Humerus Coronal Shear Fracture(AO 13-B3,Dubberley Type A)

Objective:Adequate exposure of the surgical field is a critical step in the treatment of distal humerus coronal fractures.The range of exposure varies from surgical approach to surgical approach,and it is particularly important to select the optimal surgical approach.In this study,A modified small incision approach to the anterior side of the elbow was used to compare and analyze the traditional anterolateral approach,so as to select a surgical approach with the best clinical efficacy,providing a new option for the clinical minimally invasive treatment of distal humerus Dubberley Type A fracture.Methods:A retrospective study was conducted to select 16 patients diagnosed with coronal Dubberley Type A fractures of the distal humerus who were admitted to The Third Bethune Hospital of Jilin University from June 2019 to June2023.There were 3 male patients and 13 female patients.There were 8 cases on the left and 8 cases on the right.Ages ranged from 12 to 73 years old,with a mean age of 43.5 years.According to Dubberley classification: type1 A 6 case,type 2A 7 case,type 3A 3 case.According to the different surgical approaches,they were divided into small incision approach group and anterolateral approach group.Patients in the small incision approach group were treated minimally with a modified anterior elbow small incision approach,while patients in the lateral approach group were treated with the traditional anterolateral approach.The general information of age,gender,cause of injury and site of injury,operative time(min),intraoperative blood loss(ML),postoperative complications,postoperative fracture healing time(week),Mayo elbow function score(MEPS),etc.,were compared and analyzed between the two groups.Results Statistical analysis was used to compare the effects of two surgical approaches on postoperative clinical efficacy.Results:There were no statistical differences in age,gender,injury site,length of hospital stay and other general data between the two groups(P > 0.05).The small-incision approach group was significantly higher than the anterolateral approach group in terms of operation time,intraoperative blood loss,postoperative elbow motion and elbow joint function score,with statistical significance(P < 0.05).Conclusion:Compared with the traditional anterolateral approach,the modified anterior small incision approach of the elbow has better clinical efficacy,simple anatomical level,more intraoperative visual field exposure,short operation time,less intraoperative blood loss,and good postoperative functional recovery of the elbow,which is a new minimally invasive method for the treatment of distal humerus coronal Dubberley Type A fracture.
