“…Interposition of the long head of the biceps tendon within the glenohumeral joint has also been described with an irreducible 5 Fifty-three-year-old man with a Bsuperolateral^dislocation of the right glenohumeral joint. Intra-operative images (top is superior, bottom is inferior, left is lateral, and right is medial) demonstrate tendon of the long head of the biceps after being reduced from the glenohumeral joint (in a, the arrow points to long head biceps tendon), and stitches within the subscapularis tendon during initial rotator cuff repair (in b, the arrow points to the subscapularis tendon) posterior shoulder dislocation [13]. Other less common causes of an irreducible glenohumeral joint to be considered include an entrapped fracture fragment [8,16] or surrounding nerve, such as the musculocutaneous [17] or axillary nerve [4].…”

“…Open surgical reduction is often necessary to address these injuries [6]. Irreducible anterior shoulder dislocation is well documented in the literature [7] and has been attributed to impaction of the humeral head at the glenoid [7,8], as well as interposition of the rotator cuff muscles/tendons [9][10][11][12] or long-head biceps tendon [12][13][14][15] within the joint. Interposition of the long head of the biceps tendon within the glenohumeral joint has also been described with an irreducible 5 Fifty-three-year-old man with a Bsuperolateral^dislocation of the right glenohumeral joint.…”

Irreducible superolateral dislocation of the glenohumeral joint

The overwhelming majority of glenohumeral dislocations are anterior dislocations that either spontaneously reduce or are reduced at the point of care without significant complications. Posterior dislocations are uncommon, and superior and inferior dislocations are even rarer. We present a case of "superolateral" shoulder dislocation in which the entire rotator cuff was torn either off its insertion or at the musculotendinous junction in combination with a large longitudinal split tear of the deltoid muscle. This allowed the humeral head to dislocate both superiorly and laterally into a subcutaneous position through the tear of the anterolateral deltoid muscle with an associated de-gloving soft tissue lesion. Buttonholing of the humeral head through the deltoid and interposition of the dislocated long head of the biceps tendon and macerated rotator cuff prevented closed reduction of the glenohumeral joint. The resultant radiographic appearance and treatment of this dislocation is unique. To our knowledge, this is the first reported case of this dislocation in the literature.

“…In our case, a shoulder dislocation combined with a massive rotator cuff tear allowed the tendon to dislocate. Other studies have shown posterior dislocation of the long head of biceps tendon into the shoulder joint [4,5,9,10], but due to the rarity of this condition, the literature is limited to sporadic case reports.…”

“…Dislocation of the long head of biceps tendon during glenohumeral dislocation also occurs infrequently, and when it does, it is most often in a medial direction [4]. Impediments to successful reduction are many, and can include bone, labrum, rotator cuff, or long head of biceps tendon [5]. A recent article also describes interposition of the musculocutaneous nerve as the cause of an irreducible dislocation [6].…”

Irreducible Traumatic Anterior Shoulder Dislocation Secondary to Both Subscapularis and Long Head of Biceps Tendon Interposition—A Case Report

An Irreducible dislocation of the shoulder is an uncommon event. When it does occur, blocks to reduction can include bone, labrum, rotator cuff musculature or tendon. Patients older than 40 at the time of initial dislocation are at increased risk of sustaining a concomitant rotator cuff tear. We present a case of an irreducible anterior shoulder dislocation due to interposition of both subscapularis tendon and a posteriorly dislocated long head of biceps. Both Computed Tomography (CT) and magnetic resonance imaging (MRI), along with intraoperative findings are discussed. Conclusion: We would advocate maintaining a low threshold for MR imaging post shoulder dislocation in the older population, when there is radiological or clinical concern regarding the integrity of the rotator cuff, and also to evaluate whether a concentric reduction of the shoulder joint has been achieved.

“…As reported in a few cases, some obstacles may interfere with closed reduction, including an interposed bicipital tendon (6), a subscapularis tendon (7), dislocated fragments of the anterior glenoid (8), and greater tuberosity (9).…”

Background: Although anterior shoulder dislocation is the most prevalent type of body dislocation, irreducible anterior shoulder dislocation is seldom reported in the literature, which is usually due to physical obstacles. Objectives: This study presents our findings regarding the causes of irreducibility of anterior shoulder dislocation associated with displaced fracture of the greater tuberosity. Patients and Methods:CT scans, open reduction of the joint, and internal fixation of the tuberosity was performed in seven patients with irreducible anterior shoulder dislocation associated with displaced fracture of the greater tuberosity. Results: As confirmed by intraoperative findings, the CT scans showed the cause of irreducible shoulder dislocation in six cases was the interposition of the long head of biceps (LHB) in the anterior of the head that was displaced from the fracture line between the greater and lesser tuberosities. In another case, the greater and lesser tuberosities were attached to each other and were separated from the head. This fractured part was trapped. Conclusions: We suggest that performing CT scans in all cases of anterior shoulder dislocations with displaced fracture of the greater tuberosity can help surgeons to diagnose the accompanying fractures and possible complications, such as irreducibility. If the fracture line passes through the bicipital groove or in the case of a shield fracture, possible irreducibility should be borne in mind.
