“…Interestingly, we found a relatively high incidence of calcific tendinitis among our patients with isolated infraspinatus injuries. Our findings are similar to those reported by Lunn et al 14) showing that around 68.4% of patients with isolated infraspinatus injuries (13/19) have calcific tendinitis; this is comparable to the respective value observed in our study (66.7%). These findings imply a putative role for calcific tendinitis in isolated injuries of the infraspinatus muscle.…”

“…These findings imply a putative role for calcific tendinitis in isolated injuries of the infraspinatus muscle. Regarding this subject, Lunn et al 14) suggested that the injuries may be attributed to the post insult therapies for calcific tendinitis such as steroid injections and needling rather than the pathophysiology of calcific tendinitis per se. In line with their suggestions, we saw that 3 of the 4 patients who had calcific tendinitis had had needling, aspiration, ESWT, steroid injections, and etc.…”

“…We diagnosed the tears through preoperative magnetic resonance imaging (MRI) and intraoperative arthroscopic findings and defined an isolated infraspinatus tear as an all-thickness tear of the infraspinatus alone without a combined all-thickness tear of any another cuff muscle. 14) Our definition of an isolated tear, therefore, included tears that were combined with partial tears of another cuff region. Discriminating the supraspinatus muscle from the infraspinatus muscle by insertion anatomy alone is difficult.…”

“…12,13) Studies of isolated infraspinatus injuries that are independent of any nerve injury are very rare; none have been reported in the Korean literature so far. Lunn et al 14) have reported 19 cases of isolated infraspinatus tears that are absent of any nerve injury. To this end, we investigated the following parameters in 6 patients with isolated infraspinatus tears lacking a neurological background: 1) pathological features of isolated infraspinatus tears; 2) and the clinical characteristics and outcomes after arthroscopic repair.…”

Background: Isolated infraspinatus tear is very rare and clinical features are not as well known, therefore the purpose of this study was to evaluate clinical characteristics and outcomes of isolated infraspinatus tear that authors experienced. Methods: Authors reviewed 288 cases of full-thickness rotator cuff tear involving infraspinatus between 2010 and 2015, and retrospectively analyzed six cases of isolated infraspinatus tear. Perioperative clinical characteristics, postoperative functional outcomes of 6 months were investigated. Functional evaluation included visual analogue scale (VAS), range of motions, American Shoulder and Elbow Surgeons (ASES) score, and Constant score. Results: Calcific tendinitis was accompanied in 4 cases (66.7%). Three of them received steroid injection or aspiration or extracorporeal shockwave therapy. Mean preoperative pain VAS was 7.1 (range, 5-9), and mean postoperative pain VAS at 6 months later was 1.6 (range, 0-5). Preoperative muscle strength by isokinetic muscle performance test showed 52% deficit of abduction and 37.6% deficit of external rotation. All 6 patients had arthroscopic repair of the infraspinatus tendon. All the patients at the 6 months follow-up exhibited clinical improvement in the Constant score (67.8 [range, 45-77] Conclusions: Isolated infraspinatus tendon tear was frequently accompanied by calcific tendinitis, but pathophysiologic relationship should need more study. To rule out neurogenic etiology, magnetic resonance imaging and electromyography would be helpful. Arthroscopic infraspinatus tendon repair and supraspinatus debridement showed relatively good result in painful shoulder. (Clin Shoulder Elbow 2017;20(1):30-36)

“…The slightly younger age group of the patients, the history of acute trauma, and the lack of radiographic evidence of calcific tendinitis are helpful in differentiating between these two entities. It is noteworthy, however, that some authors have reported a high incidence of calcific tendinitis amongst patients with infraspinatus myotendinous disruption [18,19], so it remains unclear if the two entities are related or if there is any overlap between them.…”

Due to the configuration of its bony elements, the glenohumeral joint is the most mobile joint of the body, but also an inherently unstable articulation. Stabilization of the joint is linked to a complex balance between static and dynamic soft tissue stabilizers. Because of complex biomechanics, and the existence of numerous classifications and acronyms to describe shoulder instability lesions, this remains a daunting topic for most radiologists. In this article we provide a brief review of the anatomy of the glenohumeral joint, as well as the classifications and the pathogenesis of shoulder instability. Technical aspects related to the available imaging techniques (including computed tomography [CT] arthrography, magnetic resonance imaging [MRI], and MR arthrography) are reviewed. We then describe the imaging findings related to shoulder instability, focusing on those elements that are important to the clinician.
