Chondroblastoma is a rare benign bone tumor typically located in the epiphysis. We describe the first case of chondroblastoma arising in the diaphysis of a long bone. ⋯ Radiographs showed a lytic lesion in the diaphysis of her right femur. A core biopsy and a subsequent surgical resection were performed.

Rosai-Dorfman disease may involve extranodal sites exclusively. Osseous involvement as the sole manifestation of disease is uncommon. The present report describes a 60-year-old woman presenting with lytic lesions in the lower end of femur and mid-fibula on one side and unaccompanied by disease elsewhere.

The role of ultrasound (US) in assessing musculoskeletal disorders is persistently increasing because of its low cost, readiness, noninvasiveness, and possibility of allowing a dynamic examination. Secondary to increased sport practice, tendon tears are more frequently observed in daily medical practice. They deserve early diagnosis to allow proper treatment that can limit functional impairment. The aim of this review article is twofold: to illustrate the US appearance of normal tendons and to describe the US findings of the most common tendon tears.

Comparative Study
Radiological assessment of lumbosacral dystrophic changes in high-grade spondylolisthesis.
To analyse radiographic correlates for the clinical status of patients and the deformation reducibility of high-grade lumbosacral spondylolisthesis. We also clarify the clinical and radiographic correlates of a new parameter for S1 dystrophy, the "S1 index". ⋯ Analysing specific criteria, we think it is possible to note progressive dystrophic changes according to the natural history of lumbosacral spondylolisthesis. We think that repeated measurements of these morphological parameters in patients diagnosed with a low-grade lumbosacral spondylolisthesis could be helpful in the early detection of evolving lumbosacral kyphosis and L5 slipping.

Case Reports
Stress-induced Salter-Harris I growth plate injury of the proximal tibia: first report.
We describe a case of chronic Salter-Harris I injury of the proximal tibial epiphysis. To our knowledge such an injury has not been described in the English language literature. The radiological appearance can mimic chronic infection. The possibility of chronic athletic stress-related change should be considered in such scenarios to avoid a misdiagnosis.
