3-Week immobilization vs. no immobilization in primary reverse total shoulder arthroplasty: A randomized controlled trial.

Background: There is no consensus about the length of the immobilization period after receiving a Reverse Shoulder Arthroplasty (rTSA) for a cuff-deficient shoulder. The objective of this study was to determine whether patients receiving an rTSA for a cuff-deficient shoulder could be managed without any immobilization after surgery.

Methods: Prospective randomized study that included a primary rTSA implanted for a cuff-deficient shoulder.

Novel Approach to Rule-Out Unnecessary Urine Bence Jones Protein Testing: A Serum Free Light Chain Algorithm.

Bence Jones proteins (BJPs) are monoclonal immunoglobulin free light chains (FLCs) that appear in the urine of patients with plasma cell disorders, including multiple myeloma (MM), Waldenström's macroglobulinemia (WM), or light chain amyloidosis (AL). Their presence can provide valuable information about disease progression and treatment efficacy. These proteins are typically detected through a 24-h urine collection, as recommended by clinical guidelines.
