Clinical Case Reports for the Evidence-Based Era

Pelvic fatigue fractures most often involve the sacrum and hip bones. Their cause is repetitive micro-injuries to which people who engage in regular sustained physical activity are exposed. One of the rarest locations of a fatigue fracture is the acetabulum of the hip joint.

Patients with severe malnutrition make up a relatively small percentage of those qualified for surgery. Often the underlying pathology involves the gastrointestinal tract and is neoplastic in nature. Preparing patient for aggressive surgical and then oncologic treatment prior to surgery is particularly complex.

Chondrosarcoma is a malignant neoplasm of the bone. It is the second most common among sarcomas of bones in adults. The early symptom is pain; in later stages, there is a tumor and distortion of the outline of the limb. The first and primary examination is a review roentgenography (X-ray) of the entire bone in two projections along with the adjacent joint. The histopathological diagnosis is established on the basis of an examination of the of tissue material taken during surgical biopsy. Treatment consists of resection of the tumor.

Membranous structures within the right atrium of the heart are a rare congenital defect that causes many diagnostic difficulties. In differentiation, we considered persistent sinus venosus valve, persistent Eustachian valve, persistent Tebezius valve, and persistent Chiari network.
