Chapter 86 highlights the imaging manifestations of osteomyelitis (OM) involving the long and flat bones. OM refers to inflammation of the bone and bone marrow caused by underlying infection, classically bacterial. Long and flat bone OM can occur either because of hematogenous spread, direct inoculation or from a contiguous source of infection. The severity depends on the factors such as organism isolated, pathogenesis, extent of bone involvement, duration of infection, and host factors such as age and immune status. Imaging plays a crucial role in the early diagnosis of OM with MRI being the modality of choice. Both acute and chronic forms of OM are still a big challenge to treat, even in the era of advanced antibiotics and new surgical techniques. Imaging helps in early diagnosis, which in turn helps to initiate early treatment.

Chondrosarcoma (CS) is a malignant tumour of long and flat bone characterised by the formation of cartilage. Mesenchymal chondrosarcoma (MCS) is a rare subtype of CS that is more aggressive and may lead to erroneous diagnosis in a limited biopsy. The diagnosis is mainly based on the histopathological appearance of biphasic pattern of undifferentiated small round cells separated by islands of well-differentiated hyaline cartilage. We report a case of 13-year-old boy who initially presented with gum swelling and the biopsy result suggested a benign fibrous lesion. Following an extensive lesion shown in radiologic findings, the tumour excision was done and finally was diagnosed as an MCS of the maxilla. The patient was given postoperative chemotherapy (EURO-EWING 99 regimen), and now on regular follow-up for monitoring of local recurrence or tumour metastasis.

BackgroundHandguns and rifles are often involved in violent deaths such as homicide and suicide. Consequently, forensic investigations are important to clarify the nature of ballistic trauma.MethodsThis study investigated the differences in entrance and exit wound morphology with Bos taurus (bovine) scapulae that have two cortical layers surrounding a central cancellous bone section which are comparable with human flat bones, with a series of experiments using six different calibres (0.22 Long Rifle, 9×19 mm North Atlantic Treaty Organization, 0.40 Smith & Wesson, 0.45 Automatic Colt Pistol, 5.56×45 mm and 7.62×51 mm). B. taurus (bovine) scapulae were used for closed range 30 cm simulated executions.ResultsThe ballistic experiments presented similarities in entrance wound morphology and exit wound bevelling with that of recognised forensic cases. As muzzle velocity increased, bevelling increased. Circumferential delamination is clearly visible with full metal jacket rounds, yielding similar bone damage morphology as human crania.ConclusionBovine scapulae seem appropriate for ballistic simulations of flat bone injuries on the macroscopic level, if the correct portion of the scapulae is deployed. More research is needed to further substantiate these interpretations.

Sternal Fractures

Chapter 7 provides an overall look at sternum fracture. The sternum is a flat bone at the anterior center of the chest, which protects the mediastinum. The sternum along with the ribs and vertebrae form the thoracic cage, which protects the thoracic organs and vessels. Fractures are usually associated with direct blunt trauma which most commonly occurs during motor vehicle accidents or from vigorous cardiopulmonary resuscitation. Significant mortality may be associated with displaced sternal fractures because of aortic, cardiac, or pulmonary injury. CT examination has surpassed radiographs in the assessment of sternal fractures and adds identification of secondary findings. It has superior sensitivity to radiography and is valuable in diagnosing serious associated injuries.
