The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code M21.859 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Playing sports, running, falling, or having an accident can damage your legs. Common leg injuries include sprains and strains, joint dislocations, and fractures. These injuries can affect the entire leg, or just the foot, ankle, knee, or hip.
Your legs are made up of bones, blood vessels, muscles, and other connective tissue. They are important for motion and standing. Playing sports, running, falling, or having an accident can damage your legs. Common leg injuries include sprains and strains, joint dislocations, and fractures.
Hip impingement syndrome, also known as femoro-acetabular impingement (FAI) syndrome, is a recently accepted pathological condition that primarily affects young and middle-aged adults. It is characterized by hip pain felt mainly in the groin, and can result in chronic pain and decreased range of motion in flexion and internal rotation. Femoroacetabular impingement (FAI) occurs as a result of friction in the hip joint caused by abnormal contact between the femoral head and the rim of the acetabulum (hip socket). Over time, the repetitive contact can cause damage to the articular or labral cartilage, which may lead to degenerative joint disease.
Grade 0: normal cartilage;#N#Grade I: cartilage with softening and swelling;#N#Grade II: a partial-thickness defect with fissures on the surface that do not reach subchondral bone or exceed 1.5 cm in diameter;#N#Grade III: fissuring to the level of subchondral bone in an area with a diameter more than 1.5 cm;#N#Grade IV: exposed subchondral bone.
The three types of FAI include excessive acetabular covering (pincer type), nonspherical femoral head (cam type) or a combination of the two. The two basic mechanisms of FAI are cam impingement (most common in young athletic males) and pincer impingement (most common in middle-aged women).
Cam Impingement is a type of impingement in which the femoral head is aspherical, which prevents it from rotating smoothly inside the acetabulum (i.e., femoral cause ). Pincer Impingement is a type of impingement in which extra bone extends out over the normal rim of the acetabulum (ie, acetabular cause).
