Background: To study if patients that have a second radiograph 2 or more years after nonoperative treatment of an isolated radial head fracture have radiocapitellar osteoarthritis (RC OA). Methods: We used the database of 3 academic hospitals in one health system from 1988 to 2013 to find patients with isolated radial head fractures (no associated ligament injury or fracture) that had a second ...
BACKGROUND Bone metabolism is a complex system, and fracture healing is one of its most important functions. Many circumstances can influence this process. Chronic drug use in elderly populations can affect bone healing, and inadequate tissue perfusion, increased free radicals and adverse drug effects can negatively influence fracture healing. Nebivolol, an anti-hypertensive drug that selective...
The circadian clock contains clock genes including Bmal1 and Period2, and it maintains an interval rhythm of approximately 24 hours (the circadian rhythm) in various organs including growth plate and articular cartilage. As endochondral ossification is involved not only in growth plate but also in fracture healing, we investigated the circadian clock functions in fracture sites undergoing heali...
Therapeutic enhancement of fracture healing would help to prevent the occurrence of orthopedic complications such as nonunion and revision surgery. Sclerostin is a negative regulator of bone formation, and treatment with a sclerostin monoclonal antibody (Scl-Ab) results in increased bone formation and bone mass in animal models. Our objective was to investigate the effects of systemic administr...
INTRODUCTION Bone marrow mesenchymal stem cells (MSCs) are undifferentiated pluripotential cells capable of differentiating into many cell types, such as osteoblasts, chondrocytes, adipocytes, myocytes, and may be a suitable autogenous cell source for articular cartilage repair. In vitro experiments show markers of chondrogenesis, such as aggrecan and collagen type II, are expressed in MSCs cul...
