The Amsterdam Wrist Rules to reduce the need for radiography after a suspected distal radius fracture: an implementation study.

PURPOSE: While most patients with wrist trauma are routinely referred for radiography, around 50% of these radiographs show no fracture. To avoid unnecessary radiographs, the Amsterdam Wrist Rules (AWR) have previously been developed and validated. The aim of the current study was to evaluate the effect of the implementation of the AWR at the Emergency Department (ED). METHODS: In a before-and-after comparative prospective cohort study, all consecutive adult patients with acute wrist trauma presenting at the ED of four hospitals were included. Primary outcome was the number of wrist radiographs before and after implementation of the AWR. Secondary outcomes were the number of clinically relevant missed fractures, the overall length of stay in the ED, physician compliance regarding the AWR, and patient satisfaction and experience with the care received at the ED. RESULTS: A total of 402 patients were included. The absolute reduction in wrist radiographs after implementation was 15% (p < 0.001). One clinically irrelevant fracture was missed. Non-fracture patients without wrist radiography due to the AWR spent 34 min less time in the ED compared with non-fracture patients who had a wrist radiograph (p = 0.015). The physicians adhered to the AWR in 36% of patients. Of all patients who did not receive a radiographic examination of the wrist, 87% were satisfied. CONCLUSION: Implementation of the AWR safely reduces the amount of wrist radiographs in selected patients and consequently reducing the length of stay in the ED.

Amsterdam wrist rules: a clinical decision aid.

BACKGROUND: Acute trauma of the wrist is one of the most frequent reasons for visiting the Emergency Department. These patients are routinely referred for radiological examination. Most X-rays however, do not reveal any fractures. A clinical decision rule determining the need for X-rays in patients with acute wrist trauma may help to percolate and select patients with fractures. METHODS/DESIGN: This study will be a multi-center observational diagnostic study in which the data will be collected cross-sectionally. The study population will consist of all consecutive adult patients (≥18 years) presenting with acute wrist trauma at the Emergency Department in the participating hospitals. This research comprises two components: one study will be conducted to determine which clinical parameters are predictive for the presence of a distal radius fracture in adult patients presenting to the Emergency Department following acute wrist trauma. These clinical parameters are defined by trauma-mechanism, physical examination, and functional testing. This data will be collected in two of the three participating hospitals and will be assessed by using logistic regression modelling to estimate the regression coefficients after which a reduced model will be created by means of a log likelihood ratio test. The accuracy of the model will be estimated by a goodness of fit test and an ROC curve. The final model will be validated internally through bootstrapping and by shrinking it, an adjusted model will be generated. In the second component of this study, the developed prediction model will be validated in a new dataset consisting of a population of patients from the third hospital. If necessary, the model will be calibrated using the data from the validation study. DISCUSSION: Wrist trauma is frequently encountered at the Emergency Department. However, to this date, no decision rule regarding this type of trauma has been created. Ideally, radiographs are obtained of all patients entering one of the participating hospitals with trauma to the wrist. However, this is ethically and logistically not feasible and one could argue that patients, for whom no radiography is required according to their physician, are not suspected of having a distal radius fracture and thus are not part of the domain. TRIAL REGISTRATION: This study is registered at the Netherlands Trial Register (NTR 2544) and was granted permission by the Medical Ethical Committee of the Academic Medical Center Amsterdam on 06-01-2011.

Internal fracture fixation using the Stoppa approach in pelvic ring and acetabular fractures: technical aspects and operative results.

BACKGROUND: The ilioinguinal approach is well established for the treatment of pelvic fractures. As an alternative, the modified Stoppa approach can be used to expose pelvic and acetabular fractures. We describe our experience with this approach in patients with pelvic and acetabular fractures with respect to fracture reduction, technical aspects, and the incidence of intra- and postoperative complications. METHODS: This retrospective study describes a series of 25 consecutive patients where a modified Stoppa approach was used for pelvic or acetabular fracture fixation. RESULTS: Fifteen patients with acetabular fractures, six patients with a pelvic ring injury not involving the acetabular joint and four patients with a combined fracture were operated through a Stoppa approach. Nine patients had a total of 13 complications, none of which required reoperation. Anatomic or satisfactory reduction was achieved in 95% of the acetabular fractures. Pelvic ring fractures had an anatomic (displacement <1 cm) postoperative result in all 10 cases. CONCLUSION: The modified Stoppa approach allows an adequate exposure and good postoperative results for treatment of pelvic ring fractures and acetabular fractures that are eligible for an anterior approach.
