Abstract

As a dynamic stabilizer and flexor of the glenohumeral joint (GHJ), the long head of the biceps brachii tendon (LHBBT) is further stabilized by the retinacular activities of the transverse humeral ligament (THL). The aim of this study was to determine the morphometric dimensions of the LHBBT and THL which were obtained from a total of forty cadaveric upper limb specimens (n = 80; Females: 36, Males: 44; Right: 40, Left: 40), were bilaterally dissected and subjected to morphometric evaluation. Results (mm): (i) LHBBT length: 81.99±21.28 Right , 79.73±17.27 Left; 79.82±19.66 Male, 82.14±19.03 Female; (ii) LHBBT width: 4.28±1.31 Right, 4.67±1.43 Left; 4.35±1.17 Male, 4.63±1.60 Female; (iii) THL length: 20.91±5.24 Right, 21.19±6.63 Left; 21.52±5.71 Male, 20.48±5.92 Female; (iv) THL width (mm): 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.
