Slipped capital femoral epiphysis (SCFE or skiffy, slipped upper femoral epiphysis, SUFE or souffy, coxa vara adolescentium) is a medical term referring to a fracture through the growth plate (physis), which results in slippage of the overlying end of the femur ().
A Southwick angle is a radiographic angle used to measure the severity of a slipped capital femoral epiphysis (SCFE) on a radiograph. It was named after Wayne O. Southwick, a famous surgeon. The angle is measured on a frog lateral view of the bilateral hips.
Klein's line or the line of Klein is a virtual line that can be drawn on an X-ray of an adolescent's hip parallel to the anatomically upper edge of the femoral neck.It was the first tool to aid in the early diagnosis of a slipped capital femoral epiphysis (SCFE), which if treated late or left untreated leads to crippling arthritis, leg length discrepancy and lost range of motion.
In early skeletal development, a common physis serves the greater trochanter and the capital femoral epiphysis. This physis divides as growth continues in a balance that favors the capital epiphysis and creates a normal neck shaft angle (angle between the femoral shaft and the neck). The corresponding angle at maturity is 135 ± 7 degrees.
Trethowan's sign is when Klein's line does not intersect the lateral part of the superior femoral epiphysis on an ... of slipped capital femoral epiphysis. See also ...
The positive Drehmann sign is a typical clinical feature in slipped capital femoral epiphysis (SCFE), the impingement syndrome of the acetabulum-hip, or in osteoarthritis of the hip joint. [ 3 ] References
Slipped capital femoral epiphyses (SCFE) usually affect 11- to 14-year-old adolescents (Figure 4). Radiographs may show widening and irregularity of the physis and posterior inferior displacement of the capital femoral epiphysis. On the AP view Klein’s line, tangent to the lateral aspect of the femoral neck, does not intersect the femoral ...
