The purpose of this study was to determine the association between measures of disease severity, impairment, and ambulation ability in persons with polyostotic fibrous dysplasia (PFD). A cross-sectional sample of 81 patients (ages 5–57) with polyostotic fibrous dysplasia was evaluated as part of an ongoing study. Subjects were scored on the Skeletal Disease Burden Score (SDBS), completed a 9-minute walk test (9MW), manual muscle testing (MMT), and measurements of range of motion (ROM). Correlations between continuous variables were calculated using the Pearson correlation coefficient and ordinal variables by Spearman correlation coefficient. It was found that subjects with more severe disease walked slower than those with less skeletal disease, with the exception of the youngest subjects. Walking velocity was faster in subjects with better hip strength and range of motion and slower in those with bilateral coxa vara. Those subjects with more severe disease had less range of motion, were weaker at the hips, and more likely to have leg length discrepancy. Skeletal disease severity was associated with hip weakness, leg length discrepancy, and loss of range of motion. Inmost cases, findings did not differ in the presence or absence of associated endocrinopathies. Skeletal disease severity, MMT and ROM each has an impact on walking efficiency in persons with PFD. These findings suggest that treatment focused on strategies to improve or, at least, maintain hip strength and range of motion, correct leg length discrepancies and hip malalignment may help preserve ambulation ability in persons with PFD and that treatment should begin at a young age.

Purpose The purpose of this article is to provide a practical review of common ultrasound (US) findings in patients presenting with acute scrotal pain. Methods We performed a literature search and reviewed numerous US cases archived in the radiology department of a large university hospital to find examples that illustrate the common US findings encountered in acute scrotal pain. Results We reviewed the literature and provided several practical examples of common US findings in patients presenting with acute scrotal pain. Conclusion Scrotal US plays a pivotal role in the evaluation of acute scrotal pain and allows proper triage of patients for conservative, medical, or surgical management due to its ability to rapidly differentiate intra versus extratesticular pathology, determine extent of trauma, and assess parenchymal perfusion.
