The Patient-rated Wrist Evaluation (PRWE) is a commonly used instrument in upper extremity surgery and research. However, to recognize treatment effect expressed as change PRWE, it important be aware of the minimum clinically difference (MCID) detectable (MDC). MCID an outcome tool like PRWE defined smallest score that likely appreciated by patient change, while MDC amount can detected measure. A numerical less than MCID, even when statistically significant, does not represent true relevant...
The aim of this study was to compare bridging external fixation with volar locked plating in patients unstable distal radial fractures regarding functional outcome. A systematic search performed the Cochrane Central Register Controlled Trials, Medline and EMBASE. All randomized controlled trials that compared directly were considered. Three reviewers extracted data independently from eligible studies using a collection form. Studies which primary endpoint measured on disabilities arm...
Background: There is no consensus as to whether displaced extra-articular distal radial fractures should be treated operatively or nonoperatively. We compared the outcomes of open reduction and volar plate fixation with closed plaster immobilization in adults an acceptably reduced fracture. Methods: In this multicenter randomized controlled trial, patients 18 75 years old fracture were randomly assigned immobilization. The primary outcome was function measured Disabilities Arm, Shoulder Hand...
The aim of this study was to develop and validate an easy use clinical decision rule, applicable in the ED that limits number unnecessary cast immobilizations diagnostic follow-up suspected scaphoid injury, without increasing risk missing fractures.A prospective multicenter conducted consisted three components: (1) derivation a prediction model for detecting fractures adult patients following wrist trauma; (2) internal validation model; (3) design rule. predictors used were: sex, age,...
In corrective osteotomy of the radius, detailed preoperative planning is essential to optimising functional outcome. However, complex malunions are not completely addressed with conventional planning. Computer-assisted may optimise results radius. We analysed pre- and postoperative radiological result computer-assisted 3D planned in a series patients malunited radius assessed function. included eight aged 13-64 who underwent for treatment symptomatic malunion. evaluated residual...
Although only 39 % of patients with wrist trauma have sustained a fracture, the majority is routinely referred for radiography. The purpose this study was to derive and externally validate clinical decision rule that selects acute in Emergency Department (ED) This multicenter prospective consisted three components: (1) derivation prediction model detecting fractures following trauma; (2) external validation model; (3) design rule. conducted EDs five Dutch hospitals: one academic hospital...
Fractures of the distal radius are common and account for an estimated 17% all fractures diagnosed. Two-thirds these displaced require reduction. Although fractures, especially extra-articular considered to be relatively harmless, inadequate treatment may result in impaired function wrist. Initial according Dutch guidelines consists closed reduction plaster immobilisation. If fracture redisplacement occurs, surgical is recommended. Recently, use volar locking plates has become more popular....
The purpose of this study was to examine the variation in surgical treatment rates patients with distal radius fractures across Dutch hospitals. We obtained all reimbursement data for 2012 and 2013 categorized by hospital. rate hospitals corrected possible explanatory variables using linear regression analyses. analysed a total 95,754 reimbursements. operative ranged from 0% 23%, mean 9.6%. Hospital type, percentage females, over 65, age, average socioeconomic status number treated explained...
This study describes a minimally invasive procedure for stabilization of the distal radioulnar joint, using suture-button construct placed percutaneously in direction oblique bundle interosseous membrane. In five cadaveric specimens, placement suspension system reduced dorsal displacement radius an unstable joint to baseline values, both neutral position and pronation supination. These results indicate possibility treatment instability.
In most hospitals, children with acute wrist trauma are routinely referred for radiography.To develop and validate a clinical decision rule to decide whether radiography in is required.We prospectively developed validated two study populations. All who presented the emergency department of four hospitals pain following were included evaluated 18 variables. The outcome was fracture diagnosed by plain radiography.Included 787 children. prediction model consisted six variables: age, swelling...
Of all distal radius fractures, 25 % are complete articular fractures (AO/OTA type C fractures). Two thirds of those displaced and require reduction. According to several International Guidelines, adequately reduced intra-articular best treated non-operatively with plaster immobilisation, while surgical fixation is suggested only when the step exceeds 2 mm after However, these recommendations based on studies that did not differentiate between intra- extra-articular fractures. Thus, no clear...
Abstract Background Acute trauma of the wrist is one most frequent reasons for visiting Emergency Department. These patients are routinely referred radiological examination. Most X-rays however, do not reveal any fractures. A clinical decision rule determining need in with acute may help to percolate and select Methods/Design This study will be a multi-center observational diagnostic which data collected cross-sectionally. The population consist all consecutive adult (≥18 years) presenting...
Objective: To externally validate the Edinburgh Wrist Calculator (EWC) in a population of patients with distal radius fractures at risk loss threshold alignment. Design: A retrospective cohort study. Setting: One academic hospital. Patients/Participants: All consecutive adult displaced fracture initial dorsal angulation >10 degree and/or an ulnar variance >3 mm who were treated closed reduction and cast immobilization between 2009 2014. Main Outcome Measurement: The sensitivity...
To our knowledge, a health economic evaluation of volar plate fixation compared with plaster immobilization in patients displaced extra-articular distal radial fracture has not been previously conducted.A cost-effectiveness analysis multicenter randomized controlled trial was performed. Ninety were randomly assigned to or immobilization. The use resources per patient documented prospectively for up 12 months after randomization and included direct medical, non-medical, indirect non-medical...
Background Carpal alignment may be used as a tool to evaluate fracture reduction in patients with distal radius fractures. However, there is little consensus on how measure and quantify carpal alignment. Purpose The aim of this study was compare the inter- intraobserver variability new perpendicular method existing fractured unfractured wrists. Additionally, normal distribution wrists investigated. Patients Methods assessed lateral plain radiographs using two different methods, one described...
Performing multiple tests in primary research is a frequent subject of discussion. This discussion originates from the fact that when are performed, it becomes more likely to reject one null hypotheses, conditional on these hypotheses true and thus commit type error. Several correction methods for testing available. The aim this study was assess quantity articles published two highly esteemed orthopedic journals which performed. secondary aims were determine percentage studies performed risk...
The Amsterdam Pediatric Wrist Rules have been developed and validated to reduce wrist radiographs following trauma in pediatric patients. However, the actual impact should be evaluated an implementation study. To evaluate effect of at emergency department. A before-and-after comparative prospective cohort study was conducted, including all consecutive patients aged 3 18 years presenting department with acute trauma. primary outcome difference number before after implementation.
