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.

Rotator Cuff Degeneration: The Role of Genetics.

J Bone Joint Surg Am 2019 Apr;101(7):600-605

Department of Anatomy, Histology, Legal Medicine, and Orthopaedics, Sapienza, University of Rome, Rome, Italy.

Background: The literature is certain regarding the multifactorial etiology of rotator cuff degeneration. However, it remains unclear if rotator cuff degeneration exclusively depends on intrinsic and extrinsic factors or if it is also genetically determined. We compared the health status of cuff tendons, evaluated with a magnetic resonance imaging (MRI) study, between elderly monozygotic and dizygotic twins with the aim of separating the contributions of genetics from shared and unique environments.

MR imaging of the postsurgical cubital tunnel: an imaging review of the cubital tunnel, cubital tunnel syndrome, and associated surgical techniques.

Skeletal Radiol 2019 Mar 28. Epub 2019 Mar 28.

Department of Surgery, Division of Plastic Surgery, Mayo Clinic, 200 First St SW, Rochester, MN, 55905, USA.

Ulnar nerve compression at the elbow, specifically the cubital tunnel, is the second most common upper extremity compression neuropathy. Many patients presenting with compression symptoms will subsequently undergo surgical intervention. We review the open surgical treatment of cubital tunnel syndrome and review the expected postoperative imaging appearance of those treatments on magnetic resonance imaging (MR), including: simple or in situ decompression, medial epicondylectomy, and anterior transposition, including subcutaneous, intramuscular, and submuscular variants.

Blood Flow-restricted Exercise Does Not Induce a Cross-transfer of Effect: An RCT.

Med Sci Sports Exerc 2019 Mar 19. Epub 2019 Mar 19.

Ohio Musculoskeletal and Neurological Institute (OMNI), Ohio University, Athens OH.

Purpose: The goal of this trial was to determine whether low-load blood flow restricted (BFR) exercise of appendicular muscles induces a cross-transfer of effect to the trunk extensor (TE) muscles, such that low-load TE exercise would enhance TE size and function to a greater extent than standard low-load exercise in people with recurrent low back pain (LBP). We also investigated the direct effects of BFR exercise in the appendicular muscles.

Methods: 32 adults with recurrent, non-specific LBP were randomized into two groups: Appendicular BFR Exercise (BFR Exercise) or Control Exercise (CON Exercise). Read More

Muscle contractility in spinobulbar muscular atrophy.

Sci Rep 2019 Mar 18;9(1):4680. Epub 2019 Mar 18.

Copenhagen Neuromuscular Center, section 3342 Department of Neurology, Rigshospitalet, University of Copenhagen Blegdamsvej 9, 2100, Copenhagen, Denmark.

Spinobulbar muscular atrophy (SBMA) is caused by a trinucleotide repeat expansion in the androgen receptor gene on the X chromosome. There is a toxic effect of the mutant receptor on muscle and neurons resulting in muscle weakness and atrophy. The weakness can be explained by wasting due to loss of muscle cells, but it is unknown whether weakness also relates to poor muscle contractility of the remaining musculature. Read More

A rare case of type 2 entrapment of the median nerve after posterior elbow dislocation with MRI and ultrasound correlation.

Skeletal Radiol 2019 Mar 13. Epub 2019 Mar 13.

Department of Orthopedics, Medical University of South Carolina, Charleston, SC, USA.

A 9-year-old boy sustained an ulnohumeral dislocation with a medial epicondyle fracture and experienced incomplete post-traumatic median nerve palsy in addition to post-traumatic stiffness following closed reduction and cast immobilization. When his motor palsy and stiffness did not improve, MRI and ultrasound were obtained, which demonstrated entrapment of the median nerve in an osseous tunnel at the fracture site, compatible with type 2 median nerve entrapment. Subsequently, the patient underwent surgery to mobilize the medial epicondyle and free the median nerve, resulting in improved range of motion, near complete restoration of motor function, and complete restoration of sensory function in the median nerve distribution within 6 months of surgery.
