Combined flexor carpi ulnaris and flexor carpi radialis transfer for restoring elbow function after brachial plexus injury
The result of combined agonist and antagonist muscle innervation in traumatic brachial plexus injury through the intraplexal fascicle nerve transfers with the same donor function has not yet been reported. We describe a patient with a C5–C7 traumatic brachial plexus injury who had a combined…

Matrix vesicles induce calcification of recipient vascular smooth muscle cells through multiple signaling pathways
In patients with chronic kidney and end-stage renal diseases, the major risk factor for progression of arterial calcification is the presence of existing (baseline) calcification. Here, we tested whether calcification of arteries is extended from calcified vascular smooth muscle cells (VSMCs) to…

Psychologic Factors Do Not Affect Placebo Responses After Upper Extremity Injections: A Randomized Trial
BACKGROUND: Studies on how psychologic factors influence the placebo effect have shown conflicting results in an experimental setting. Pessimists are more likely to experience a nocebo effect (feel worse after an inert intervention), whereas other studies suggest that patients with more symptoms of…

The Incidence of Arthroplasty After Initial Arthroscopy for Trapeziometacarpal Arthrosis
Background: It remains unclear how many patients undergo secondary surgery after initial arthroscopy for trapeziometacarpal (TMC) arthrosis. We studied the factors related to secondary TMC arthroplasty after TMC arthroscopy. We also examined secondary questions of: (1) what percentage of patients…

Incidence and Functional Outcomes of Scapholunate Diastases Associated Distal Radius Fractures: A 2-year Follow-Up Scapholunate Dissociation
BACKGROUND: The Scapholunate Interosseous Ligament (SLIL) is the first intrinsic carpal ligament to be injured in wrist trauma, present in up to 64% of the distal radius fractures. However, it remains unclear what patients develop symptoms, making primary treatment of these injuries accompanying…

Interobserver Variability of Radiographic Assessment Using a Mobile Messaging Application as a Teleconsultation Tool
BACKGROUND: To examine whether interobserver reliability, decision-making, and confidence in decision-making in the treatment of distal radius fractures changes if radiographs are viewed on a messenger application on a mobile phone compared to a standard DICOM viewer. METHODS: Radiographs of distal…

What Is the Effect of Vitamin C on Finger Stiffness After Distal Radius Fracture? A Double-blind, Placebo-controlled Randomized Trial
BACKGROUND: It is proposed that vitamin C administration can reduce disproportionate pain and stiffness after distal radius fracture; however, randomized trials that tested this hypothesis have had inconsistent results. QUESTIONS/PURPOSES: (1) Is administering vitamin C after distal radius fracture…

Annexin-Mediated Matrix Vesicle Calcification in Vascular Smooth Muscle Cells
In bone, osteoblasts and chondrocytes synthesize matrix vesicles (MVs) that interact with collagen to initiate calcification. MVs have been identified in human calcified arteries but are poorly characterized. The objective of this study is to determine the role of annexins and fetuin-A in MV…
