The aim of the Scaphoid Magnetic Resonance Imaging in Trauma (SMaRT) trial was to evaluate the clinical and cost implications of using immediate MRI in the acute management of patients with a suspected fracture of the scaphoid with negative radiographs. Patients who presented to the emergency department (ED) with a suspected fracture of the scaphoid and negative radiographs were randomized to a control group, who did not undergo further imaging in the ED, or an intervention group, who had an MRI of the wrist as an additional test during the initial ED attendance. Most participants were male (52% control, 61% intervention), with a mean age of 36.2 years (18 to 73) in the control group and 38.2 years (20 to 71) in the intervention group. The primary outcome was total cost impact at three months post-recruitment. Secondary outcomes included total costs at six months, the assessment of clinical findings, diagnostic accuracy, and the participants’ self-reported level of satisfaction. Differences in cost were estimated using generalized linear models with gamma errors.Aims
Patients and Methods
We conducted an observational radiographic study
to determine the inter- and intra-observer reliability of the AO classification
of fractures of the distal radius. Plain posteroanterior and lateral
radiographs of 456 patients with an acute fracture of the distal
radius were classified by a consultant orthopaedic hand specialist
and two specialist trainees, and the k coefficient for the inter-
and intra-observer reliability of the type, group and subgroup classification
was calculated. Only the type of fracture (A, B or C) was found to provide substantial
intra-observer reliability (k type 0.65). The inclusion
of ‘group’ and ‘subgroup’ into the classification reduced the inter-observer
reliability to fair (kgroup 0.29, ksubgroup =
0.28) and the intra-observer reliability to moderate (kgroup 0.53,
ksubgroup 0.49). Disagreement was found to arise between
specific subgroups, which may be amenable to clarification. Cite this article:
