AIM To evaluate minimal fixation method with Kirschner's wires in the treatment of open fractures of the hand and foot short bones, caused by explosive devices. METHOD There were 270 wounded persons with open fractures of hand and foot short bones, who were surgically treated at the Department of Surgery at the Osijek University Hospital. The stabilization of an unstable open fracture was per...

The mechanical behavior of the transosseous elements is a defining factor in the overall stiffness, stability, and reliability of an external fixation system. Mechanics involving the application of thin Kirschner wires in Ilizarov apparatus is yet to be fully explained. To address this problem, load-deflection behavior of the pretensioned thin wires laterally loaded by the bone is necessary to ...

PURPOSE To report the outcome of revised total hip arthroplasty procedures involving an anterior cortical window, extensive strut allografts, and an Exeter impaction graft. METHOD Eight patients (9 hips) with a mean age of 58 years underwent revision of total hip arthroplasty using the Exeter hip impaction graft system and strut allografts between 1995 and 1998. An extensile anterior approach...

INTRODUCTION Modified, reversal technique of fixation in digital replantation using K-wires was analyzed. The results obtained from the standard technique and reversal technique of fixation using K-wires were compared. OBJECTIVE The aim was to compare the results of osteofixation using K-wires in digital replantation when either standard or reversal, modified technique was used. METHODS A r...

BACKGROUND AND PURPOSE Fixation of unstable trochanteric fractures is challenging. Application of a circumferential wire may facilitate bone contact and avoid postoperative fracture displacement. However, the use of circumferential wires remains controversial due to possible disturbance of the blood supply to the underlying bone. We evaluated the results of applied circumferential wires, concen...

The purpose of this study was to analyze the relative biomechanical stability of three types of internal fixation with cancellous bone graft in a cadaveric, scaphoid nonunion model. A scaphoid nonunion model was created by removing a volar wedge of bone from the waist of the scaphoid in 18 fresh frozen human cadavers. Cancellous sawbone graft was inserted into the osteotomy site and three group...

BACKGROUND The aim of this study was to evaluate the interaction of bioactive and biodegradable poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (PBGHA) and poly (lactide-co-glycolide)/bioactive glass (PBG) nanocomposite coatings with bone. MATERIALS AND METHODS Sol-gel derived 58S bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite na...

BACKGROUND The aim of this study was to compare the stiffness characteristics of Taylor Spatial Frame (TSF) fixed with transverse wires and half pins. DESIGN & METHODS Experiments were carried out at the biomechanics laboratory at Cardiff University. All mechanical testing was performed with a servo hydraulic test frame (MTS 858 Mini Bionix II(R), MTS Corp., Mineapolis, USA). Custom built mou...

Pins and wires offer the simplest and most effective tools for managing bone fractures and dislocations. Migration of these devices within the chest is rare, but can cause serious problems. The spontaneous migration of Kirschner wires from the right clavicle to the mediastinum resulted in penetrating injury of the esophagus and pseudo-aneurysm of the brachiocephalic artery in an 84-year-old pat...

BACKGROUND Non-surgical treatment of forearm shaft fractures in adults is associated with a high incidence of non-union. Operator errors during surgery also often result in bone union complications. We attempted to identify the errors made during the treatment or other factors that might influence the development of forearm shaft union complications. MATERIALS AND METHODS We have analysed the...
