Surgical fixation of humeral shaft fractures generally involves plating or nailing. It is unclear whether one method is more effective than the other. The aim of this study was to compare the results of the intramedullary nail and locking compression plate for the treatment of humeral shaft fractures. A total of 60 patients with humeral shaft fractures were randomized to undergo surgery with an...

Background: Distal humeral fractures accounts for approximately 2% of all fractures and nearly one-third of humeralfractures in adults. In this regard, Modified Tension Bind Wiring (MTBW) technique was used for the fixation of the distalhumeral fractures type A2 and C1 (AO) to evaluate the early movement and complications of the patients.Methods: This study was conducted on 25...

Methodological problems in studies of union commitment were identified and illustrated with data from 4,641 members and 479 stewards in 297 local teachers' unions. Using a 20-item union commitment scale, results confirmed the existence of 3 substantive factors and 1 method factor at the individual level of analysis: loyalty to the union, responsibility to the union, willingness to work for the ...

The authors use British workplace data for 1980-98 to examine whether increased human resource management (HRM) practices coincided with union decline, consistent with the hypothesis that such practices act as a substitute for unionization. Two initial analyses show no important differences between union and non-union sectors or between newer workplaces (which are likelier to be non-union) and ...

The aim of this study was to assess the results of percutaneous injection of autologous bone marrow in the treatment of fractures presenting with delayed union or non union after internal fixation. Twenty consecutive patients presenting to our outpatient clinic with internally fixed fractures with delayed union or non union were included in the study. The time between the index surgery and the ...

the eu, which has its roots in the early fifties, in a short time reached nearly all aims to which the founders had refereed. establishing the major institutions and promoting its member states to cooperate in economic, social, political and recently in military issues, the eu is going to attain the old aspiration of the europeans, i.e., a united states of europe. in this regard, the conclusion...

We performed a comparative study of iliac bone graft (the iliac bone group) and carbon cage with local bone graft (the cage group) in PLIF to evaluate the clinical results of both methods. We examined both groups about the operating time, the estimated blood loss, the operative results using the score rating system of Japanese Orthopaedic Association (JOA score), and the presence of bone union ...

This study, using National Labor Relations Board data and American Hospital Association data, reports on the status of union election activity in the hospital industry for a 65-month period, January 1980-May 1985, and contrasts it with earlier data for a similar 65-month time period (1974-79). Together these data provide a comprehensive overview of union election activity in non-Federal, nongov...

We show that the number of vertices, edges, and faces of the union of k convex polyhedra in 3-space, having a total of n faces, is O(k + kn log k). This bound is almost tight in the worst case, as there exist collections of polyhedra with Ω(k + knα(k)) union complexity. We also describe a rather simple randomized incremental algorithm for computing the boundary of the union in O(k + kn log k lo...
