Stress fractures typically result from repeated abnormal mechanical loading to the bones. In particular, multiple stress fractures may occur in patients with systemic disease, such as rheumatoid arthritis, osteoporosis, or osteoarthritis. Adefovir dipivoxil (ADV), a nucleotide analogue of adenosine monophosphate, very rarely causes severe hypophosphatemia when using a low dosage of 10 mg daily for treatment of chronic hepatitis B. To the best of our knowledge, in English literature, this is the first report of multiple stress fractures in a chronic hepatitis B patient who has been treated with a low dosage of ADV. We think it is important to consider that use of ADV in a patient with chronic hepatitis B could be a risk factor for stress fractures.
Stress fractures of the anterior tibial cortex are prone to complete fracture because these stress fractures occur on the tension side of the bone. Recently, surgical treatments are preferred in high-performance athletes requiring rapid return to sports. We report our experience of a case in which stress fracture of the anterior tibial cortex was treated using anterior tension band plating in a male athlete and successful bony union and rapid return to sports were achieved.

We reports two cases of femoral stress fractures, one at femoral neck, the other at distal femur. Femoral stress fracture is not uncommon in reported literature, but most of reported cases limited in military recruits and athlethes. There are few reports about femoral stress fractures of civilians. Early dignosis is difficult because complaints are vague and poorly localized, so displacement occurs and misdiagnosis is made. The purpose of this report is to call attention to the importance of early diagnosis of stress fracture of the femur so that displacement and misdiagnosis, which may lead to prolonged in capacitation or to the necessity for surgical intervention, may be prevented.
