喙突的解剖形态学测量及其临床意义

Anatomical morphometry of the coracoid process and its clinical significance

目的测量喙突的解剖形态和空间相对位置,为肩关节疾病的诊断和治疗提供解剖学基础。方法收集干燥、完整肩胛骨标本165例,左侧61例,右侧104例。测量喙突重要结构的形态参数:3个宽度,3个厚度,3个长度,4个距离,3个角度,并对测量结果进行统计和分析。结果左侧和右侧喙突尖的宽度为(13.40±3.09~14.42±2.84)mm、厚度(8.41±1.51~9.07±1.63)mm、喙突尖到折返部长度(38.77±4.54~40.77±4.55)mm、折返部到基底部长度(20.03±2.04~19.18±2.40)mm、喙突尖到肩胛上切迹直线距离(45.20±4.21~47.03±4.00)mm,具有统计学意义(P<0.05),而喙突的其它解剖形态和空间相对位置差异无统计学意义(P>0.05)。结论本研究对喙突的解剖形态和空间相对位置进行了全面测量,为肩关节疾病的诊断和治疗提供了解剖学依据,并有助于提高肩关节疾病的手术安全性,降低手术风险。

Objective To measure the anatomical morphology and spatial relative position of the coracoid process, and to provide anatomical basis for diagnoses and treatments of shoulder joints diseases.Methods A total of 165 dry and intact scapulae of Chinese population were collected(61 left and 104 right).Morphological parameters of important structures of the coracoid process were measured: three widths, three thicknesses, three lengths, four distances and three angles. Measurement results underwent statistical analysis.Results The width and thickness of the coracoid tip was(13.40 ± 3.09~14.42 ± 2.84) mm and(8.41 ± 1.51~9.07±1.63) mm, respectively. The length from coracoid tip to precipice and from coracoid precipice to base(38.77± 4.54~40.77±4.55) mm and(20.03±2.04~19.18±2.40) mm, respectively; The distance from coracoid tip to suprascapular notch(45.20±4.21~47.03±4.00) mm on the left and right sides was significantly different(P<0.05), while the remaining anatomical morphology and spatial relative position of the coracoid process had no significant difference(P>0.05). Conclusions The comprehensive measurement of anatomical morphology and spatial relative position of the coracoid process can provide an anatomical basis for diagnosis and treatment of the shoulder joints diseases, improving the safety and reducing the risk of surgery involving the shoulder joint diseases.
