BACKGROUND Severe glenoid bone loss in recurrent anterior glenohumeral instability is rare and difficult to treat. PURPOSE The authors present a surgical technique using allogeneic bone grafting for open anatomic glenoid reconstruction in addition to the capsular shift procedure. STUDY DESIGN Case series; Level of evidence, 4. METHODS Nine consecutive(More)
Statins inhibit 3-hydroxy-3-methylglutaryl-coenzyme A reductase, which catalyzes the conversion of 3-hydroxy-3-methylglutaryl-coenzyme A to mevalonate, a rate-limiting step in cholesterol synthesis. Statins are able to reduce cardiovascular risk in hypercholesterolemic patients. In recent years, the possible effect of statins on bone tissue has received(More)
The effects of low intensity pulsed ultrasound to tenocytes and osteocytes are well understood and applied clinically. However, its effects on cultured Schwann cells are still not well elucidated. This study was designed to elucidate the effects of low intensity pulsed ultrasound on cultured Schwann cells and their possible molecular mechanism. Schwann(More)
Management of presacral hemorrhage has always been a challenge for surgeons because such bleeding can rapidly destabilize a patient during pelvic surgery. Conventional hemostatic measures are often effective for arresting this type of hemorrhage, however, sometimes conventional measures make the problem worse. A number of alternative hemostatic techniques(More)
BACKGROUND The treatment of adhesive capsulitis is a dilemma for orthopaedic rehabilitation specialists. In this study, we assessed whether extracorporeal shockwave therapy (ESWT) improves the functional outcome of primary shoulder adhesive capsulitis. METHODS In this prospective, randomized, controlled, single-blind clinical trial, we enrolled 40(More)
BACKGROUND/PURPOSE Technetium-99m methylene diphosphonate (Tc-99m MDP) whole-body bone scintigraphy (BS) has been widely used for detecting bone metastases. The aim of this study is to investigate the diagnostic accuracy of BS in detecting skeletal metastases for hepatocellular carcinoma (HCC) patients. In addition, the anatomic distribution of the(More)
Recent advances in tissue engineering have led to potential new strategies, especially decellularization protocols from natural tissues, for the repair, replacement, and regeneration of intervertebral discs. This study aimed to validate our previously reported method for the decellularization of annulus fibrosus (AF) tissue and to quantify potentially(More)
Several plate systems for high tibial osteotomy (HTO) have been developed to stabilize the opening wedge of an osteotomized tibia. Among them, the TomoFix system, having a quasi-straight and T-shaped design, has been widely adopted in the literature. However, this system is implemented by inserting a lag (i.e., cortical) screw through the proximal(More)
Experimental and numerical methods have been extensively used to simulate the lumbar kinematics and mechanics. One of the basic parameters is the lumbar loads. In the literature, both concentrated and distributed loads have been assumed to simulate the in vivo lumbar loads. However, the inconsistent loads between those studies exist and make the comparison(More)
