Abstract
Diagnostic imaging plays an important role in the detection, management, and follow-up of skeletal and soft tissue injuries. The use of routine radiography to identify fractures constituted one of the earliest applications of this technique. Fractures represent incomplete or complete breaks in the continuity of bones, which may result from a single episode of excessive stress applied to normal bone, multiple episodes of excessive stress applied to normal bone, or normal or excessive stress applied to abnormal bone. Injuries may be due to direct trauma, load applied directly upon the osseous structures, or more commonly due to indirect forces applied through muscles or tendons.

Publisher Summary This chapter focuses on the biomechanical properties of bones. Bone is a physiologically dynamic tissue whose primary functions are to provide a mechanical support system for muscular activity, provide for the physical protection of organs and soft tissues, and act as a storage facility for systemic mineral homeostasis. The resulting structure of the skeleton is influenced heavily by mechanical principles, acting both as constraints and as driving forces in its architecture. Th...

PURPOSE: To assess the value of magnetic resonance (MR) imaging for enabling the classification of fracture mechanisms and to compare marrow edema caused by compressive forces with that caused by tensile forces. MATERIALS AND METHODS: In 62 knees or shoulders, 78 fractures were identified prospectively on MR images or plain radiographs; compressive or tensile forces were determined retrospectively to have caused impaction or distraction fractures, respectively. Edema was measured on T1-weighted ...

Spiral (helical) computed tomography (CT) involves continuous patient translation during x-ray source rotation and data acquisition. As a result, a volume data set is obtained in a relatively short period of time. For chest or abdominal scanning, an entire examination can be completed in a single breath hold of the patient or in several successive short breath holds. The data volume may be viewed as conventional transaxial images or with multiplanar and three-dimensional methods. The authors rev...

Because determination of neurologic integrity after severe limb trauma is crucial in patient care, the authors assessed magnetic resonance (MR) imaging as a tool to map denervated motor units of skeletal muscle in patients with traumatic peripheral neuropathy. Denervation was confirmed in 22 patients with use of electromyography, surgery, or both. MR imaging was performed with moderately T1- and T2-weighted spin-echo and short-tau inversion-recovery (STIR) sequences. MR imaging was unreliable in...

In brief MRI can prove diagnostically brief useful for a number of osseous injuries that active patients may incur. The authors weigh the benefits of MRI, such as early injury detection and excellent contrast and spatial resolution, versus its shortcomings, such as high cost and sensitivity to motion. In addition, they describe in detail the MRI appearances of stress fractures, bone bruises, occult fractures, and osteochondral fractures.

Stress fractures are extremely common lesions that occur in specific areas and are related to specific activities. They are caused by increased muscular activity on bones that are not yet ready to take the increased pull of the involved muscles. The insufficiency type of stress fractures found in patients with bone of diminished mineral content is being recognized more often as increasing numbers of middle-aged and elderly persons are becoming more physically active. A variety of imaging studies...

ABSTRACT. Background. Stair falls are commonamong young children and are also common false histo-ries in cases of child abuse. When a child presents with afemur fracture and a stair-fall history, a judgment ofplausibility must be made. A lack of objective injury andbiomechanical data makes plausibility determinationmore difficult. Our objective was to characterize keyfeatures associated with femur fractures from reportedstair falls, to develop a model for assessing injury plau-sibility (IP). Met...

Fractures are the second most common presentation of child abuse and may be a marker of an especially volatile and high-risk form of abusive trauma. Abuse is an escalating form of trauma: once a child sustains a fracture, regardless of intentionality, it is highly likely that further harm will occur. Up to 50% of children diagnosed with abusive trauma have healing fractures. The possibility of concomitant injuries of the brain or abdomen must also be considered, even in the absence of symptoms, ...

Publisher Summary This chapter discusses the application of computational impact biomechanics to the consequences of real world passenger car accidents on human occupants, using computer models in numerical simulations with industrial crash codes. The corresponding developments are illustrated on the subject of safety simulations of human passenger car occupants. With some adaptations, the developed models apply equally well to the simulation of pedestrian accidents and to the design for occupan...
