Spontaneous Dislocation and Destruction of Tendon of Long Head of Biceps Brachii

Macro/micro observational studies of fibres maintaining the biceps brachii tendon in the bicipital groove: application to surgery, pathology and kinesiology

“…Meyer [11] in 1928 stated that dislocations of the long head of the biceps brachii tendon occurred either deep to or within the substance of the subscapularis. Moreover, Deutsch et al [6] observed that 6 out of 13 patients with full thickness subscapularis tears on MRI had an apparent medial subluxation/dislocation of the tendon of the long head of the biceps brachii.…”

“…Davis [5] wrote, "This [biceps] tendon is rarely luxated because it is firmly held in place by the transverse humeral ligament". Meyer [11] observed that in shoulders with biceps brachii tendon dislocations, the THL was actually intact. Snow et al [16] described THL as anatomic region consisting of 2 layers of tissues, a thin superficial layer of fibres in distinct bundles and deep layer consisting of fibres from the rotator cuff tendons, the coracohumeral ligament, subscapularis and supraspinatus tendon.…”

3D Bicipital Groove Shape Analysis and Relationship to Tendopathy

“…3,4,6 Previous studies typically take a single set of 2D measurements of width, depth, and medial wall angle for each BG, either from a dry bone or a radiograph. Additionally, previous researchers note the presence/absence of the supratubercular ridge of Meyer (henceforth referred to as Bthe ridge^) on each BG, which is a ridge of bone projecting immediately proximal to the medial wall of the bicipital groove and continuous with it, 2 and is considered to have an impact on the tendency for dislocation of the LBT. These measurements of width, depth, medial wall angle, and presence/absence of the ridge shall henceforth be referred to as the Bclassical measurements^for brevity.…”

“…Each data set was also labeled according to observation, by a boardcertified radiologist, of the supratubercular ridge of Meyer. 2 3. Computation of 3D shape descriptor.…”

Occupational cervicobrachial syndromes. A review.

“…Bicipital tendinitis has been found in 10 to 20 Ofo of routine autopsies (20,31,56,110), often combined with rotator cuff tendinitis or rupture, but it can manifest itself also as an isolated entity (30,48,73,82) in as many as 60 Ofo of all cases of shoulder pain (17).…”
