Can platelet-rich plasma therapy save patients with ulnar collateral ligament tears from surgery?

Regen Ther 2019 Jun 22;10:123-126. Epub 2019 Mar 22.

Global Care Medical Center of Canlubang, Laguna, Philippines.

Introduction: Platelet-rich plasma (PRP) has been shown to be effective in treating partial tears of the ulnar collateral ligament (UCL) of the elbow in overhead throwing athletes, but it is still unknown whether it has a role in complete tears. The aim of this study was to assess the effectiveness of PRP in treating complete as well as partial UCL tears. We hypothesized that trephination of the injured UCL followed by injection with PRP can promote healing of both partial and complete tears. Read More

Editorial Commentary: I Have a Hip Labral Tear? Well, That Makes Sense Because I Had a Labral Tear in My Shoulder Too.

Authors:
Joshua D Harris

Arthroscopy 2019 Apr;35(4):1080-1082

Most acetabular labral tears are caused by abnormal osseous morphology, such as cam and/or pincer morphology and dysplasia. There is a high prevalence of asymptomatic cam morphology, pincer morphology, dysplasia, and acetabular labral tears in the general population. The addition of subjective patient symptoms and objective physical examination findings to imaging (plain radiographs, magnetic resonance imaging, and computed tomography) may yield the diagnosis of femoroacetabular impingement syndrome.

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.
