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.

We hypothesized that nonstructural factors, including metrics of psychological well-being and preoperative narcotic use, would correlate with higher pain levels postoperatively and that structural factors, such as tear size, would not be predictive.

Methods: Ninety-three patients were prospectively enrolled and evenly distributed by tear size. Read More

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.
