Pectoralis major tendon transfer for recurrent anterior shoulder dislocation after primary surgery in an elderly patient: A case report.

Medicine (Baltimore) 2019 Feb;98(5):e14264

Department of Orthopaedic Surgery, Soonchunhyang University Hospital Cheonan, Cheonan, Korea.

Rationale: Adequate stability of traumatic anterior shoulder dislocation without any obvious damage to the anterior capsulolabral structure in elderly patients can be achieved by treating the associated rotator cuff injuries. However, in case of recurrent shoulder dislocation despite rotator cuff repair, the repaired rotator cuff may be weakened or reruptured and is often impossible to repair again. Therefore, the role of the rotator cuff as a shoulder stabilizer cannot be expected. Read More

The presence of a rotator cuff tear interferes with age-dependent muscle atrophy of intact shoulder muscles. An MRI study with 3 years' follow-up.

Hum Mov Sci 2018 Dec 26;62:161-168. Epub 2018 Oct 26.

Department of Orthopaedics, Leiden University Medical Center, the Netherlands. Electronic address:

Rotator cuff muscle atrophy is frequently studied, but it is unknown whether redistribution of mechanical load in the presence of a rotator cuff tear influence muscle atrophy that is observed in patients. We hypothesized that in the presence of a supraspinatus tear, redistribution of mechanical load towards teres minor and deltoid slows down atrophy of these muscles over time. In this retrospective observational study of 129 patients, we measured the cross-sectional surface-areas on MRI of shoulder muscles in an intact rotator cuff (n = 92) and in a supraspinatus-tear group (n = 37) with a mean follow-up of 3 ± 1.

Acromioclavicular joint cyst formation in a patient with rotator cuff-tear arthropathy: a rare cause of shoulder discomfort.

BMJ Case Rep 2018 Sep 27;2018. Epub 2018 Sep 27.

Department for Shoulder and Elbow Surgery, Charite Universitatsmedizin Berlin Campus Virchow-Klinikum, Berlin, Germany.

We report a case of a 77-year-old man who presented to our shoulder department with a soft tissue mass on his right acromioclavicular (AC) joint. Previously attempted puncture aspiration had revealed serous fluid retention which recurred after each of several drainage attempts. Conventional radiography and MRI of the affected shoulder joint demonstrated a progressed cuff-tear arthropathy with an irreparable tear of the supraspinatus tendon, static superior migration of the humeral head, opening of the AC joint capsule and a superior joint-fluid 'eruption' and accumulation called 'Geyser sign'.

A Large Size Lipoma at Spinoglenoid Notch Mimicked Traumatic Rotator Cuff Tear.

J Hand Surg Asian Pac Vol 2018 Jun;23(2):267-269

* Department of Orthopedic Surgery, Myongji Hospital, Goyang, Korea.

Herein, we report a large lipoma at the spinoglenoid notch that mimicked a rotator cuff tear, which occurred in a 61-year-old male farmer. Weakness and pain in the shoulder started abruptly after hard labor, and our first impression was a traumatic rotator cuff tear; however, there was no tear on MRI, and complete marginal excision of a large lipoma at the spinoglenoid notch relieved the symptoms completely at a postoperative three-month follow-up visit. We believe that certain activities such as forceful shoulder abduction may have caused the sudden onset of suprascapular neuropathy in the loosely compressed suprascapular nerve by the lipoma.

ACR Appropriateness Criteria Shoulder Pain-Traumatic.

J Am Coll Radiol 2018 May;15(5S):S171-S188

Specialty Chair, Mayo Clinic, Phoenix, Arizona.

Traumatic shoulder pain is pain directly attributed to a traumatic event, either acute or chronic. This pain may be the result of either fracture (the clavicle, scapula, or proximal humerus) or soft-tissue injury (most commonly of the rotator cuff, acromioclavicular ligaments, or labroligamentous complex). Imaging assessment of traumatic shoulder pain begins with conventional radiography and, depending on physical examination findings, will require MRI or MR arthrography for assessment of soft-tissue injuries and CT for delineation of fracture planes.

Multimodality imaging of subacromial impingement syndrome.

Skeletal Radiol 2018 Jul 14;47(7):923-937. Epub 2018 Feb 14.

Department of Orthopedic Surgery, Clinique du Sport, 2 Rue George Negrevergne, 33700, Mérignac-Bordeaux, France.

Subacromial impingement syndrome results from irritation of the tendons of the rotator cuff muscles in the subacromial space and may manifest as a range of pathologies. However, subacromial impingement is a dynamic condition for which imaging reveals predisposing factors but no pathognomonic indicators. Also, the usual imaging features of subacromial impingement may be seen in symptomatic and asymptomatic patients. Read More
