This paper will focus on the use and including a demonstration of Digital photography for the purpose of clinical documentation, audit, teaching and research. Digital photography is particularly suitable in upper &
lower limb surgery because of the discrete regional anatomy and radiology. Digital images once created and stored do not deteriorate, unlike pictures or slides. Digital camera that uses a single floppy disc has an added advantage of simplicity and ease of storage. Pre-op, intra-op, and post-op images of patients undergoing hand surgery and treatment are easily documented with the camera. The information can be archived using commercially available filing software such as File MakerPro. The information can be retrieved at a later stage to be used in audit, teaching and research, with the images retained in their original, unmodified condition. Existing clinical, historical and teaching library slides, pictures or images can be archived to ensure the quality of the images do not deteriorate further, and for ease of retrieval and subsequent application. Archiving in this manner would require a slide scanner. The ease of file retrieval, reliability and accuracy of this imaging system has been tested using a minimum of 2000 patient files, using both PC and Macintosh systems, with no computer error and minimal operator errors found. The software used has “auto save” feature built in, hence computer “crash resistance.” The only limitation of the technology is the set up costs, and the resolution of the images. Fortunately, both these limitations are improving rapidly.
In an unselected series of 55 cases of slipped capital femoral epiphysis (SCFE) we observed an incidence of 25% of epiphyseal reduction, mostly unintentional. Reduction indicated physeal instability and was associated with an effusion, detected by sonography on admission, and inability to bear weight. The true prevalence of instability may be higher since an effusion was noted in 33 cases (60%) on the initial sonographic assessment. Serial radiographs showed reduction in 12 (22%), with an average change of 15.1 degrees in the head-neck angle. Serial sonography showed reduction in 7 out of 20 cases (35%), with an average change of 3.7 mm in displacement. In two cases reduction was seen on sonography but not on radiography. Of the hips which showed subsequent reduction, 12 had had a bone scan on admission; three showed initial epiphyseal avascularity but only one progressed to symptomatic avascular necrosis. All stable hips had normal epiphyseal vascularity on the initial bone scan. This indicates the importance of injury from the initial displacement in causing avascular necrosis, rather than effusion, vascular compromise or iatrogenic injury from gentle repositioning. Physeal instability in SCFE is common and should be assessed clinically on admission. It is indicated by joint effusion or inability to bear weight. A slip is very unlikely to be unstable in a child able to bear weight and with no sonographic effusion.
The ultrasonic findings in 38 children with osteomyelitis of the limb bones were analysed in four time-related groups based on the interval between the onset of symptoms and the ultrasonic examination. Deep soft-tissue swelling was the earliest sign of acute osteomyelitis; in the next stage there was periosteal elevation and a thin layer of subperiosteal fluid, and in some cases this progressed to form a subperiosteal abscess. The later stages were characterised by cortical erosion, which was commonly present in those who had had symptoms for more than a week. Concurrent septic arthritis was revealed in 11 patients, most frequently in association with osteomyelitis of the proximal femur or the distal humerus. Four weeks after clinical cure, ultrasonic examination showed no abnormalities. Ultrasonography is therefore a useful additional method for the diagnosis and assessment of osteomyelitis and its complications.
