肩胛骨关节盂长短径解剖测量及临床意义

Anatomical measurement and clinical significance of line of apsides in glenoid

目的通过测量肩关节盂长短径形态数据,分析数据之间相关性,指导关节盂骨缺损的预估。方法选取青岛大学解剖室完整成对肩胛骨标本共50对(100例),进行编号后根据左右侧进行分组,分别测量关节盂长径,关节盂短径,并进行统计学分析处理。结果100例肩胛骨标本中,各项数据平均值分别为:关节盂长径(35.46±3.29)mm,关节盂短径(26.11±3.20)mm。左右侧分组平均值:左侧关节盂长径(35.28±3.81)mm,右侧关节盂长径(35.24±3.31)mm,左侧关节盂短径(25.83±3.18)mm,右侧关节盂短径(26.38±3.23)mm,左右侧关节盂短径存在相关性(P<0.05,r=0.882,R^2=0.777),线性关系式为:y(右侧关节盂短径)=2.907+0.869x(左侧关节盂短径)。关节盂长径与短径存在相关性(P<0.05,r=0.810,R^2=0.657),线性关系式为:y(关节盂短径)=-1.816+0.787x(关节盂长径)。结论左、右侧关节盂短径间以及同侧关节盂长、短径间存在正相关性;该相关性可修正人工测量关节盂最佳拟合圆直径的误差,指导临床术前预估关节盂骨缺损范围。

Objective To measure the glenoid morphology of the shoulder,analyze the correlation between the data and to guide the prediction of glenoid defects.Methods A total of 50 pairs(100 cases)of shoulder specimens were collected from the anatomy department of Qingdao University.The specimens were divided into groups according to the left and right sides after numbering.The longitudinal diameter of the glenoid and the transverse diameter of the glenoid were measured respectively.Then the statistical analysis was conducted.Results In the 100 scapular specimens,the mean values of the data were as followings:longitudinal diameter of the glenoid cavity was(35.46±3.29)mm and transverse diameter of the glenoid cavity was(26.11±3.20)mm,respectively.The average values of the left and right side were as followings:longitudinal diameter on the left side of the glenoid cavity was(35.28±3.81)mm;the right side was(35.24±3.31)mm,transverse diameter on the left side of the glenoid cavity was(25.83±3.18)mm,and the right side was(26.38±3.23)mm.There was a correlation between transverse diameter on the left side of the glenoid cavity and transverse diameter on the right side of the glenoid cavity(P<0.05,r=0.882,R^2=0.777).The linear relation was:y(transverse diameter on the right side of glenoid cavity)=2.907+0.869x(transverse diameter on the left side of the glenoid cavity).There was a correlation between the longitudinal and transverse diameter of the glenoid joint(P<0.05,r=0.810,R^2=0.657).The linear relationship was y(transverse diameter of the glenoid joint)=-1.816+0.787x(longitudinal diameter of the glenoid joint).Conclusions There are positive correlations between the longitudinal diameter of the glenoid joint and the transverse diameter of the glenoid joint,between transverse diameter on the left and right side of the glenoid cavity.The correlation can reduce the error of artificial subjective measurement of the best-fit circle diameter of the glenoid cavity,and can predict the area of anterior glenoid bone loss before clinical operation and improve the prognosis.
