摘要

目的观察肱二头肌长头腱（Long Head of the Biceps Tendon, LHBT）起点处的形态特征，并划分解剖类型，为肩关节疾患诊治或韧带重建提供解剖学依据。方法选取128例结构完整的人体肩关节标本，解剖LHBT的起点处，测量起点处的宽度和厚度，依据起点处的特征进行分类。结果（1）根据LHBT起点特征及其与前后盂唇的关系分为：①Ⅰ型，LHBT起自肩胛骨盂上结节16例（12.5%）；②Ⅱ型，LHBT仅起自盂上结节后方的盂唇25例（19.5%）；③Ⅲ型，LHBT起自盂上结节及其后方盂唇82例（64.1%）；④Ⅳ型，LHBT起自肱骨大结节2例（1.6%）；⑤Ⅴ型，LHBT起自盂上结节及前、后盂唇3例（2.3%）。（2）Ⅰ、Ⅱ、Ⅲ型LHBT起点宽度分别是（5.11±0.65） mm、（6.44±1.12） mm、（5.63±1.41） mm，三者比较具有统计学差异（P<0.05）；男、女性LHBT起点宽度分别是（5.95±1.43） mm、（5.13±0.74） mm，二者比较具有统计学差异（P<0.05）。LHBT的起点类型在男、女性（P>0.05）及左、右侧（P>0.05）比较，均无统计学差异。结论 LHBT起自盂上结节及其后方的盂唇，是最多见的解剖学类型；认识LHBT的解剖及变异特征，对于肩关节镜或肩部韧带重建手术，具有重要意义。

Abstract

Objective To the morphological characteristics at the origin of the long head of the biceps tendon (LHBT), and clarify the anatomical types based on cadaveric dissection, so as to provide anatomical basis for the diagnosis and treatment of shoulder joint disorders or ligament reconstruction. Methods A total of 128 human shoulder joint specimens were examined, and the types of origin of LHBT were classified. The width and thickness of the origins were measured with a vernier caliber. Classification was performed according to the characteristics of the starting point. Results (1) Based on the characteristics at the origin of LHBT and its relationship with SLAP, it can be classified as followings: Type I, LHBT entirely originated from the supraglenoid tubercle in 16 cases (12.5%); Type II, LHBT originated from the posterior part of the glenoid labrum at the supraglenoid tubercle in 25 cases (19.5%); Type III, LHBT originated from both supraglenoid tubercle and the superior glenoid labrums in 82 cases (64.1%); Type IV, the LHBT originated from greater tuberosity of humerus in 2 cases (1.6%); Type Ⅴ, LHBT originated from supraglenoid tubercle, anterior and posterior glenoid labrums in 3 cases (2.3%). (2) The widths of LHBT origin in type I, type II, and type III were (5.11±0.65) mm, (6.44±1.12) mm, and (5.63±1.41) mm, respectively, and there were statistically significant differences among the three types (P<0.05). The widths of LHBT origin in male and female were (5.95±1.43) mm and (5.13±0.74) mm respectively, and there were statistically significant difference between the two groups (P<0.05). There was no statistically significant difference in the type of LHBT origin between males and females (P>0.05) or between the left and right sides (P<0.05). Conclusions LHBT originates from the supraglenoid tubercle and the posterior part of the glenoid labrums, and is the most common anatomical type. Understanding the anatomy and variant characteristics of LHBT is of great significance for shoulder arthroscopy or shoulder ligament reconstruction surgery.
