The use of low-energy extracorporeal shock wave therapy (ESWT) has recently been introduced in pseudoarthrosis, fracture, and wound healing for both clinical and experimental purposes. In this study, we created an experimental rat model to investigate the histopathological and biochemical effects of ESWT in the healing of tendon injury that may accompany(More)
The effects of extracorporeal shock waves (ESWT) on tendon healing were assessed by observing histological and biomechanical parameters in a rat model of injury to the tendo Achillis. The injury was created by inserting an 18-G needle through tendo Achillis in 48 adult Wistar albino rats. The animals were divided into three groups. The first group received(More)
Ciprofloxacin hydrochloride-loaded microspheres were prepared by a spray-drying method using pectin and chitosan. The effects of different polymers and drug ratios were investigated. The most appropriate carriers were selected by in vitro testing. A rat methicillin-resistant Staphylococcus aureus osteomyelitis model was used to evaluate the effects of the(More)
PURPOSE The aim of this study was to prepare poly(D,L-lactide-co-glycolide) (PLGA) microspheres containing sodium fusidate (SF) using a double emulsion solvent evaporation method with varying polymer:drug ratios (1:1, 2.5:1, 5:1) and to evaluate its efficiency for the local treatment of chronic osteomyelitis. METHODS The particle size and distribution,(More)
BACKGROUND Musculoskeletal hydatidosis is very rare and represents 1%-5.4% of all cases of echinococcosis. On clinical basis, infection mimics a soft-tissue tumor, and the preoperative radiological diagnosis is very important to avoid biopsy. CASE PRESENTATION We report an unusual case of primary subcutaneous hydatidosis in proximity to vastus lateralis(More)
Intraosseous ganglion cysts of the carpal bones located in the lunate are one of the rarely seen pathologic conditions. Here we present a case of the penetrating type of intraosseous ganglion cyst located in the lunate as an uncommon cause of wrist pain. The patient was successfully treated by surgical intervention. Intraosseous ganglion cyst should be(More)
The biodegradable chitosan microspheres containing vancomycin hydrochloride (VANCO) were prepared by spray drying method with different polymer:drug ratios (1:1, 2:1, 3:1 and 4:1). Thermal behaviour, particle size and distribution, morphological characteristics, drug content, encapsulation efficiency, in vitro release assessments of formulations have been(More)
INTRODUCTION Extracorporeal shock waves (ESW) have been extensively studied in the field of orthopedics. Experimental and focused, well-designed clinical studies have suggested the clinical utilisation of ESW in several pathologies including delayed bone union, tennis elbow, and plantar fasciitis. However, the unwanted detrimental effects of ESW on various(More)
OBJECTIVES The aim of this study is to compare the effect of extracorporeal shock wave therapy (ESWT) on fractures with intact periosteum and excised periosteum. MATERIALS AND METHODS Thirty-seven Wistar albino rats were randomized into four groups. Osteotomy and intramedullary Kirschner wire fixation were performed on all right femurs under ketamin(More)
