“…Pure LHBT lesions are relatively rare; they are frequently accompanied by RC injury (3)(4)(5)(6)(20)(21)(22)(23). At present, the clinical diagnosis of LHBT lesions is challenging and the condition is easily neglected (42). Another challenge for surgeons is the selection of the appropriate treatment following diagnosis (21,43).…”

The curative effect of small-incision open distal subpectoral vs. arthroscopic proximal biceps tenodesis for lesions in the long head of the biceps tendon (LHBT) combined with rotator cuff repairs (RCR) has remained controversial. The aim of the present study was to compare the two surgical methods. A total of 71 patients who received surgical treatment for LHBT lesions accompanied by RC tears were analyzed. Following arthroscopic RCR and tendectomy of the affected LHBT, 35 patients underwent small-incision open distal subpectoral tenodesis through a small incision (the subpectoral group), while the remaining 36 patients received arthroscopic proximal tenodesis (the arthroscopic group). The surgery time and intra-operative blood loss were compared between the two groups. In addition, the clinical outcomes were evaluated using scoring systems for the functional assessment of the shoulder joint. The subpectoral group had a shorter surgery time and less intra-operative blood loss than the arthroscopic group (P<0.05). The functional scores of the two groups significantly improved as time passed (P<0.05). The subpectoral group was significantly superior to the arthroscopic group with regard to the American Shoulder and Elbow Surgeons score at 2 weeks post-operatively and visual analog scale score at 2 weeks and 3 months post-operatively (P<0.05). Small-incision open distal subpectoral and arthroscopic proximal tenodesis were demonstrated to effectively improve the function of the shoulder joint and relieve pain caused by LHBT lesions accompanied by RCR. However, small-incision open distal subpectoral tenodesis had the additional advantage of shorter surgery time, less intra-operative bleeding and encouraging early results compared to arthroscopic proximal tenodesis. The study was registered as a clinical trial in the Chinese Trial Registry (no. ChiCTR1800015643).

Background The definition of the entrance of the bicipital groove (EBG) is still unclear, and the relationships between the EBG and lesions of the long head of the biceps brachii tendon (LBT) and biceps pulley complex (BPC) have long been controversial. The purpose of this anatomic and imaging study was to define the EBG and to examine morphological parameters, classifications, and their relationships with lesions of the LBT and BPC. Methods One hundred thirteen unpaired intact dry humeri, 34 cadaveric shoulder specimens and 278 shoulder images were collected, measured, and classified based on morphological characteristics. Soft tissue and bony landmarks of the EBG were classified into different types. The relationships between the types and lesions of the LBT and BPC were analyzed through an anatomic and imaging study. Results Type II, type A and type i of the EBG and type b of the adjacent articular surface accounted for most of the dry humeri, cadavers, and images. Based on the EBG classification in the superoinferior image view, all of the subluxations and dislocations were classified as type B (61/120, 50.83%; χ2 = 16.55, P < 0.001), and most LBT and BPC lesions were type B (65/117, 55.56%; χ2 = 26.05, P < 0.001). LBTs were injured in (χ2=, P < 0.001) 83.56% of type B, 100% of type C, and 95.83% of type iii EBGs (χ2 = 135.69, 31.89, all P < 0.001). Similarly, BPCs were injured in 89.04% of type B and 93.10% of type C EBGs (χ2 = 153.14, P < 0.001), while BPCs were injured in 95.8% of type iii EBGs (χ2 = 33.79, P < 0.001). Conclusions The EBG is an anatomical concept worthy of clinical attention. Anatomical variations in the EBG correlated with lesions of the LBT and BPC. LBT and BPC lesions correlated with type B and C EBGs by imaging analysis.

“…The BB is characterized by morphological variability, both in the number of muscle bellies [1,5,11,16,18,21,22] (48), proximal attachments [3,15,19,37,43] (49), and the variability of its distal attachment, which is much less frequently described in the literature [8,23,39] (50).…”
