BACKGROUND Despite extensive literature supporting the use of computerized tomography (CT) scans in evaluating scaphoid fractures, there has not been a consensus on the methodology for defining and quantifying union. The purpose of this study was to test the inter-observer reliability of two methods of quantifying scaphoid union. METHODS The CT scans of 50 non-operatively treated scaphoid fra...

OBJECTIVE The aim of the study was to identify factors contributing to the development of non-union after fixation of diaphyseal humeral fractures using Hackethal's intramedullary nailing technique. METHODS In the time period from 2001 to 2010 156 patients with diaphyseal humeral fractures were treated surgically using Hackethal's technique. Six of them (3.8%) developed non-union. This group ...

In this paper, we study on the EREW-PRAM model a parallel solution to the extended set union problem with unlimited backtracking which maintains a dynamic partition Π of an n-element set S subject to the usual operations Find, Union, Backtrack and Restore as well as the new operations SetUnion, MultiUnion. The SetUnion operation is a special case of the commonly known Union operation aimed to u...

Background Open reduction internal fixation of displaced 3 and 4-part proximal humerus fractures is an effective treatment modality particularly for the younger age group, but it is not without complications. Fixed angled locking screw plates are the mainstay of fixation. The A.L.P.S. Proximal Humerus Plating System is a new implant that has smooth locking pegs in the place of humeral head scre...

Abstract Background Treatment for distal diaphyseal or metaphyseal tibia fractures is challenging and the optimal surgical strategy remains a matter of debate. The purpose this study was to compare plate fixation with nailing in terms operation time, non-union, time-to-union, mal-union, infection, subsequent re-interventions functional outcomes (quality life scores, knee- ankle scores). Methods...

INTRODUCTION Open fractures of the tibia pose a challenge to orthopaedic and plastic surgeons. A retrospective observational review was conducted to evaluate the epidemiological factors and fracture outcomes in the Singapore context. METHODS A nine-year period of open tibial shaft fractures presenting to our institution was reviewed. Demographic and management data were recorded. Statistical ...

Abstract: Using linked employer-employee data from the 1998 Workplace Employee Relations Survey, we investigate the impact of collective bargaining institutions on the incidence and intensity of formal training provided by employers to employees. Initially using only variables from the employee survey, we find that private sector men and full-time women covered by unions typically receive signi...

BACKGROUND Pulsed electromagnetic fields (PEMF) stimulation for the treatment of bone nonunion or delayed union have been in use for several years, but on a limited basis. The aim of this study was to assess the overall efficacy of the method in tibial delayed unions and nonunions and identify factors that could affect the final outcome. METHODS We prospectively reviewed 44 patients (27 men) ...

Tibial fracture is the most common long bone fracture. Because of the superficial location of the tibia, surgery is usually required for the treatment of fractures to achieve union. The goal of this study was to evaluate the effect of decortication on the faster union of fractures treated with compression plates. In this clinical trial, conducted from 2009 to 2013, 42 patients were randomly ass...
