Tomography Versus Computed Tomography for Assessing Step Off in Intraarticular Distal Radial Fractures

Distal radius fractures and radiographic assessment: a systematic review of measurement accuracy

“…The process of obtaining cadaver arms was not clearly specified in the studies using cadaver arms as reference standard (15–17). Selection bias can therefore not be sufficiently evaluated, although we consider the risk of bias to be minimal.…”

“…explicitly ensure that no error is introduced in the time interval between index test and reference standard. They repeat the reference standard measurements to ensure that handling the specimen during the radiographic procedure has not dislocated the fracture (16,17). QUADAS-2 results are presented in Table 3.…”

“…Two out of six radiographic measurements varied significantly from the caliper measurements. Overall accuracy is not reported (17).…”

Lunate–Lunate Facet Ratio and Variance to Predict Articular Gap After Distal Radius Fracture

“…15 Despite the success of CT in evaluating the fractured wrist, it is not the imaging technique of first choice, and concerns exist regarding its widespread use. 9,16,18,19 Generalized routine use of CT scanning may result in a delay in treatment and increased health care costs. 9 Pruitt et al have suggested that CT scans be restricted to patients who are surgical candidates or for whom further information is required regarding the extent of articular involvement.…”

Intra-articular fractures of the distal radius

“…10 Nonetheless, Kreder et al 9 found that measurements of articular step and gap made by experienced surgeons on standard radiographs varied substantially. Other investigators have found that the use of tomography 11 or computed tomography 10,11 can improve the reliability of the measurements, but that there is still only moderate agreement between observers and with repeated measurements. Others claim that the only reliable method to assess articular congruity is direct evaluation by using arthroscopy.…”
