Skins come from calves, foals, sheep, goats, and other small animals (young camels and seals). Hides are the skins of cattle, horses, donkeys, camels, deer, elk, walruses, and whales. Pigskin raw materials are the skins of domestic and wild swine. In addition to these most important types of leather raw materials, the skins of reptiles (crocodiles, lizards, and snakes) and fish (wolf-fish, cod, burbot, sheatfish, dog salmon, giant sturgeon, and shark) are also used.
If x-rays are normal, an MRI or bone scan is a more accurate way of diagnosing a stress fracture. The area where stress fractures of the hip occur is called the femoral neck. This is where the hip joint connects to the femur (the thigh bone).
A stress fracture, also known as a hairline fracture, is a fatigue-induced fracture of the bone caused by repeated stress over time.Instead of resulting from a single severe impact, stress fractures are the result of accumulated trauma from repeated submaximal loading, such as running or jumping.tress fractures most commonly present as pain with weight bearing that increases with exercise or activity. The pain usually subsides with rest but may be constantly present with a more serious bone injury. There is usually an area of localized tenderness on or near the bone and generalized swelling to the area.
