Radiologic case study. Fractures of the foot masquerading as ankle injuries.

An ankle radiographic series frequently is obtained when a patient presents with an acute ankle and foot injury. Although many fractures are confined to the ankle and are readily apparent, fractures of the foot can mimic ankle injuries. It is important to differentiate these fractures of the foot from the more common ankle sprain. Most ankle sprains are treated with ice, compression, and elevation, followed by range-of-motion exercises and progressive weight bearing as tolerated. When foot fractures are not identified, however, lack of appropriate treatment can result in late complications. Concentration on key areas as described here will reduce the incidence of missed fractures of the foot in these patients.

Comparison of 4 computed tomographic imaging protocols for lateral tibial plateau fractures.

OBJECTIVE: Many computed tomographic (CT) imaging protocols are used for pretreatment assessment of tibial plateau fractures. This study compares the diagnostic capabilities of 4 CT protocols. METHODS: Lateral tibial plateau fractures were induced in 19 knee specimens and CT scans were obtained with the following protocols: 1) 3-mm collimation, axial acquisition, 2) 3-mm collimation, helical acquisition, 3) mixed-increment collimation, axial acquisition, and 4) 3-mm collimation, helical acquisition with 50% overlap reconstruction of raw data. Two-dimensional coronal and sagittal reformations and 3-dimensional surface reconstruction images were analyzed for maximum fragment depression, peripheral fragment displacement, fracture pattern classification and quality of image. Specimen dissection established maximal articular surface depression, fragment displacement and actual fracture pattern. RESULTS: None of the 2-dimensional reformations from the 4 protocols proved statistically superior for determining maximal fracture depression, fragment displacement, or fracture classification. There was a trend toward more accurate fracture classification with the mixed-increment axial protocol and the overlap protocol than either of the 3-mm protocols, but this was not statistically significant. All protocols were statistically equivalent in predicting fracture pattern classification using 3-dimensional images. However, the 3-dimensional images were of significantly higher quality when obtained with either the mixed-increment axial protocol or the overlap protocol. CONCLUSIONS: There were no statistically significant differences in the objective assessment of tibial plateau fractures among the 4 different protocols. The 3-dimensional images derived from the mixed-increment axial protocol and the 3-mm helical protocol with 50% overlap reconstruction were of superior quality.

Enlarged peroneal process with peroneus longus tendon entrapment.

A 50-year-old man was treated conservatively for chronic bilateral ankle pain for several years. Plain radiographs obtained following exacerbation of symptoms showed bilateral enlarged peroneal processes. CT and MRI demonstrated bony detail of the unusual processes and also showed isolation of the peroneus longus tendons and associated tendinitis and partial tears.

Multifocal vascular lesions of bone: imaging characteristics.

OBJECTIVE: Multifocal vascular processes which arise in bone are a very inhomogeneous class of diseases. Four of these processes are derived from endothelial precursors, however, and share a similar radiographic spectrum. These four entities are reviewed in order to clarify their imaging patterns and the diagnostic utility of imaging modalities. METHODS: Eight cases of cystic angiomatosis, multifocal hemangioma, hemangioendothelioma and angiosarcoma presenting to a tertiary referral center over a 7-year period were reviewed. The medical literature was also reviewed for information concerning the imaging of these processes. RESULTS: All four diseases produced radiolucent defects on plain radiographs with variable margination reflecting the aggressiveness of the lesions. Computed tomography was used to examine five patients and provided supportive, though generally non-diagnostic, information in the five cases in which it was performed. Radionuclide bone scintigraphy, as reported in the literature, underestimated the extent of skeletal involvement in all eight cases, though some lesions were identified. Radionuclide imaging with labeled red blood cells, performed in three cases, did not add any information, which is contrary to some reports in the literature. Magnetic resonance imaging proved the most sensitive for identifying lesions, although the imaging characteristics were not diagnostic. CONCLUSIONS: Plain radiographs are the mainstay for imaging multifocal endothelial processes. Radiographs provide information on aggressiveness, multifocality and distribution of lesions. Computed tomography provides similar information. Magnetic resonance imaging often detects additional lesions. The insensitivity of radionuclide bone scintigraphy is surprising. Reports of unique deposition of radionuclide in tagged red blood cell scanning has been reported to support the diagnosis of vascular lesions, but it did not do so in these cases.

Distal radioulnar joint arthrography: simplified technique.

Three-compartment arthrography has been advocated in the current literature for evaluation of the intrinsic ligaments of the wrist. Previous techniques for distal radioulnar joint (DRUJ) injection introduce the needle directly into the joint space. As is done in shoulder arthrography, however, the needle tip can be positioned at the distal-radial margin of the ulnar head, allowing it to lie within the capsule. Retrospective review of 45 cases of wrist arthrography with this technique disclosed no complications.

Longitudinal tibial stress fracture.

Fatigue-type stress fractures occur following repetitive loading of normal bone. These occur frequently in the tibia, although vertical orientation to the fracture is much less common than transverse orientation. Without a convincing history of new or accelerated muscular activity, imaging can be difficult to interpret and evaluation may require more than one imaging modality to exclude other diagnostic considerations, including neoplasm and osteomyelitis.

Radiologic case study. Trevor disease: dysplasia epiphysealis hemimelica.

Although Trevor disease is a rare entity, early recognition is important because early treatment can decrease or prevent limitation in some patients. The clinical presentation and radiographic appearance in combination are unique, enabling both a precise diagnosis and the development of an appropriate management scheme.

Radiologic case study. Plain film manifestations of ACL injury.

ACL injuries are common but often difficult to diagnose acutely by clinical examination alone. The Segond fracture, avulsion fracture of the anterior tibial spine, impacted lateral femoral condyle fracture, and fracture of the posterior lateral tibial plateau are radiographic signs often associated with ACL injury. It is important to recognize the significance of these subtle abnormalities and if found, further evaluation should be done to identify the presence and the extent of ACL injury as well as potential injury to other components of the knee joint. MRI is the imaging method of choice in these patients. Early diagnosis and treatment of knee joint abnormalities may help prevent or diminish long-term disability.
