Effect of kartogenin-loaded gelatin methacryloyl hydrogel scaffold with bone marrow-stimulation for enthesis healing in rotator cuff repair
Strategies involving microfracture, biomaterials, growth factors, and chemical agents have been evaluated for improving enthesis healing. Kartogenin (KGN) promotes selective differentiation of bone marrow mesenchymal stem cells (BMSCs) into chondrocytes. Gelatin methacryloyl (GelMA) is a promising biomaterial for engineering scaffolds and drug carriers. Herein, we investigated KGN-loaded GelMA hydrogel scaffolds with a bone marrow-stimulating technique for the repair of rotator cuff tear. (Source: Journal of Shoulder and Elbow Surgery)

Survivorship of Autologous Structural Bone Graft at a Minimum of Two Years when used to address Significant Glenoid Bone Loss In Primary and Revision Shoulder Arthroplasty: A CT and clinical Review.
Severe glenoid bone loss remains a challenge in patients requiring shoulder arthroplasty and often requires autogenous bone grafting. The purpose of this study was to assess the integrity of the bone graft at two years in a series of primary and revision shoulder replacements where glenoid bone loss was managed using a structural autograft (humeral head or iliac crest bone graft) in combination with a trabecular titanium implant.

The Influence of Reverse Arthroplasty Humeral Component Design Features on Scapular Spine Strain
Reverse shoulder arthroplasty (RSA) humeral implant parameters have been previously studied with respect to range-of-motion, deltoid function, and stability. However, limited literature exists on the influence of humeral design features on scapular spine strain. The purpose of this cadaveric biomechanical simulator study was to evaluate the role of humeral component lateralization and neck-shaft angle (NSA) on scapular spine strain.

The Bankart Repair: Past, Present, and Future.
Arthur Sidney Blundell Bankart was a London-based Orthopedic surgeon who discovered the essential lesion in recurrent anterior shoulder instability in 1923. He pioneered a technique, the Bankart repair, to re-establish stability to the glenohumeral joint, without sacrificing native joint motion. In this article, the original Bankart repair is compared to the modern arthroscopic Bankart repair, accompanied by a surgical video of Blundell Bankart performing the Bankart repair in 1951, shortly before his death.

Biodegradable Magnesium versus Polylactide Pins for Radial Head Fracture Stabilization: A Biomechanical Study
Biodegradable implants gain increasing importance for the fixation of simple displaced radial head fractures to supersede implant removal and to minimize cartilage destruction. Commonly used polylactide pins still lead to higher rates of secondary loss of reduction compared to metal implants. Alternatively, implants made from a magnesium alloy meanwhile are available in a pin design which hypothetically could perform superior to polylactide pins. Since biomechanical data of clinical applications are lacking, the goal of the present study was to biomechanically compare magnesium pins to polylactide pins using a Mason type I...

Trends in reimbursement for primary and revision total elbow arthroplasty
Relative Value Units (RVU) are an essential component of reimbursement calculations from the Center for Medicare and Medicaid Services (CMS). RVU are calculated based on physician work, practice expense, and professional liability insurance. Procedures that are more complex, such as revision arthroplasty, require greater levels of physician work and should therefore be assigned a greater RVU. The purpose of this study is to compare RVU assigned for primary and revision total elbow arthroplasty. (Source: Journal of Shoulder and Elbow Surgery)

The purpose of this study was to evaluate the clinical and radiographic outcomes of a transosseous suture fixation technique for the treatment of unstable lateral clavicle fractures. The appropriate treatment for lateral clavicle fractures is controversial. Many authors have argued for nonsurgical treatment of these injuries; however, recent literature has shown a role for the surgical treatment of unstable fractures. The paucity of lateral clavicular bone and the unique anatomy of this area of the shoulder makes surgical treatment of these injuries challenging. (Source: Journal of Shoulder and Elbow Surgery)
