PURPOSE To assess the treatment outcome of temporary coracoclavicular screw fixation for displaced distal clavicle fractures. METHODS From January 1995 to December 2003, 30 consecutive patients with Neer type II displaced distal clavicle fractures were treated with open reduction and internal fixation using a coracoclavicular screw. The screw was removed under local anaesthesia after bony uni...

Disassembly for recycling purposes is an emerging area of research that offers many advantages over more traditional means of recycling. However, many technical challenges are involved in automated disassembly. This paper addresses one of the critical challenges involved: diagnostics in the unscrewing operation. The various conditions that can arise when one attempts to unscrew a screw (one of ...

OBJECTIVE To report that screw-in type pacing leads can be removed by screw retraction even after a significant anchoring period. PATIENT A 78-year-old woman who visited our hospital for skin erosion over a pacemaker that had been implanted 3 years previously and had migrated from the subclavicular area to the axilla. METHODS Culture revealed a local staphylococcus infection. We placed a ne...

A 59-year-old female presented to our institution with paraparesis caused by medullar compression secondary to multiple myeloma. Spinal cord decompression and transpedicular spine fixation were performed. A month later, the patient complained of sudden pain in her middle back. A CT scan revealed screw impingement on the aortic wall at T8 level. A thoracic stent-graft was deployed before removin...

This study aimed to present the mechanical performance evaluation of the dynamic hip screw (DHS) for trochanteric fracture by means of finite element method. The analyses were performed based on stainless steel and titanium implant material definitions at various stages of bone healing and including implant removal. The assessment of the mechanical performance used two parameters, von Mises str...

BACKGROUND In treatment of unstable trochanteric fractures dynamic hip screw and Medoff sliding plate devices are designed to allow secondary fracture impaction, whereas intramedullary nails aim to maintain fracture alignment. Different treatment protocols are used by two similar Swedish regional emergency care hospitals. Dynamic hip screw is used for fractures considered as stable within the r...

INTRODUCTION Locked plates are commonly used to obtain fixation in periarticular and comminuted fractures. Their use has also gained popularity in repairing fractures in osteoporotic bone. These plates provide stable fixation and promote biological healing. Over the last 3 years, we have used over 150 locked plates with varying success to fix periarticular fractures involving mainly the knee an...
