Unreamed Intramedullary nailing and external fixation are 2 major treatments widely used in Gustilo grade III open tibial fractures, but the difference in effectiveness and complication remains controversial. We retrieved original publications of comparative studies from medical literature databases and selected 9 of them for a meta-analysis. Observation items include malunion and deep infectio...

BACKGROUND Little is known about the prevalence of proximal humeral non-union. There is disagreement on what constitutes union, delayed union and non-union. Our aim was to determine the prevalence of these complications in proximal humeral fractures (PHFs) admitted to trauma hospitals. METHODS The Victorian Orthopaedic Trauma Outcomes Registry identified 419 cases of PHFs, of which 306 were a...

A model family is a set of related models in given language, with commonalities and variabilities that result from evolution over time and/or variation intended usage (the spatial dimension). As the size increases, it becomes cumbersome to analyze individually. One solution represent using one global supports analysis. In this paper, we propose concept union as complete concise representation a...

PURPOSE To evaluate treatment results of intramedullary fixation using multiple Kirschner wires for diaphyseal forearm fractures. METHODS Between January 2001 and January 2004, 184 patients (122 men and 62 women) with 288 displaced diaphyseal forearm fractures underwent intramedullary fixation using multiple Kirschner wires. The wires were inserted by opening the fracture site because radiogr...

BACKGROUND Lower tibial bone fracture may easily cause bone delayed union or nonunion because of lacking of dynamic mechanical load. OBJECTIVE Research Group would design a new instrument as Rap System of Stress Stimulation (RSSS) to provide dynamic mechanical load which would promote lower tibial bone union postoperatively. METHODS This clinical research was conducted from January 2008 to ...

OBJECTIVES The purpose of this study was to compare union rates for isolated subtalar arthrodesis with and without the use of bone grafts or bone graft substitutes. METHODS We retrospectively reviewed 135 subtalar fusions with a mean follow-up of 18 ± 14 months. The standard approach was used for all surgeries. Graft materials included b-tricalcium phosphate, demineralized bone matrix, iliac ...

BACKGROUND Treatment of septic long bone non-union remains a complex therapeutic problem. External stabilisation with Konzal's "R" fixator has been used in the Orthopaedic Department of CPME for years and allows for rigid stabilisation of bone fragments and good mutual alignment. Tried and tested in the treatment of osteitis, the fixator, however, offers limited possibilities for dynamisation a...
