As a dynamic stabiliser and flexor of the glenohumeral joint, the long head of the biceps brachii tendon (LHBBT) is further stabilised by the retinacular activities of the transverse humeral ligament (THL).
The LHBBT and THL which were obtained from a total of 40 cadaveric upper limb specimens (n = 80; females: 36, males: 44; right: 40, left: 40), were bilaterally dissected and subjected to morphometric evaluation.
The results are in millimetres. LHBBT length: 81.99 ± 21.28 right, 79.73 ± 17.27 left; 79.82 ± 19.66 male, 82.14 ± 19.03 female; LHBBT width: 4.28 ± 1.31 right, 4.67 ± 1.43 left; 4.35 ± 1.17 male, 4.63 ± 1.60 female; THL length: 20.91 ± 5.24 right, 21.19 ± 6.63 left; 21.52 ± 5.71 male, 20.48 ± 5.92 female; THL width: 16.65 ± 6.92 right, 16.63 ± 7.49 left; 16.83 ± 6.65 male, 16.40 ± 7.84 female. With larger LHBBT length observed on the right side and larger LHBBT width observed on the left side; both parameters appeared to be distinctly longer in female individuals. On the contrary, the THL length and width were evidently greater in male individuals, with larger lengths and widths present on the left and right sides respectively.
These findings may contribute to South African literature and to clinical knowledge as these parameters are important in the successful outcomes of tenotomy, tenodesis and shoulder-related procedures.
作为盂肱关节的动态稳定器和屈肌，肱二头肌长头腱（LHBBT）通过横肱韧带（THL）的关节囊活动得到进一步稳定。
从总共 40 个尸体上肢标本（n=80；女性：36 例，男性：44 例；右侧：40 例，左侧：40 例）中获得 LHBBT 和 THL，对其进行双侧解剖并进行形态计量评估。
结果以毫米为单位。LHBBT 长度：右侧 81.99±21.28，左侧 79.73±17.27；男性 79.82±19.66，女性 82.14±19.03；LHBBT 宽度：右侧 4.28±1.31，左侧 4.67±1.43；男性 4.35±1.17，女性 4.63±1.60；THL 长度：右侧 20.91±5.24，左侧 21.19±6.63；男性 21.52±5.71，女性 20.48±5.92；THL 宽度：右侧 16.65±6.92，左侧 16.63±7.49；男性 16.83±6.65，女性 16.40±7.84。右侧 LHBBT 长度较大，左侧 LHBBT 宽度较大；女性个体的这两个参数明显较长。相反，THL 长度和宽度在男性个体中明显较大，左侧和右侧的长度和宽度均较大。
这些发现可能为南非文献和临床知识做出贡献，因为这些参数在成功进行腱切断术、腱固定术和肩部相关手术中非常重要。
