Bone marrow is the tissue inside bones that forms the various blood cell types. Marrow is mainly “red marrow” in babies, and over decades, as fat normally replaces part of the marrow, it becomes “yellow marrow.” Yellow marrow can turn back into red marrow when there is increased oxygen demand. This can be seen in athletes (such as marathon runners), heavy cigarette smokers and people with congenital red blood cell problems (such as sickle cell disease).
Enchondromas are benign cartilage-forming tumors that develop in the marrow cavity of long bones. They account for approximately 3% of benign bone tumors.The signs and symptoms vary depending upon the anatomic site, extent, and distribution of involvement. Most enchondromas are asymptomatic (do not cause symptoms) unless a fracture is present or impending. They often are incidental findings (found in passing when looking for something else).
During hip replacement, a surgeon removes the damaged sections of the hip joint and replaces them with parts usually constructed of metal, ceramic and very hard plastic. This artificial joint (prosthesis) helps reduce pain and improve function.
There is a spot (lesion) on your femur (thigh bone) that looks like a collection of fibers and cysts (i.e. fibrocystic). When it is located in this part of the femur, it is also called an impingement cyst. Impingement cysts can be associated with a syndrome called femoroacetabular impingement (FAI) where the femur is too tight against the hip, causing increased friction with hip movements.
Hip impingement, also known as femoroacetabular impingement (FAI), is a condition in which there is abnormal and wearing contact between the ball and socket of the hip joint. The result is increased friction during hip movements that may damage the joint.
Cancer that has spread from the original (primary) tumor to the bone.
