Nov 13, 2024 · The line of Klein describes an arbitrary line drawn along the superior edge of the femoral neck on the frontal projection, which is useful in detecting early slipped upper femoral epiphysis in children and adolescents.
Trethowan sign | Radiology Reference Article | Radiopaedia.org
Feb 15, 2024 · The Trethowan sign is used to diagnose slipped capital femoral epiphysis (also called slipped upper femoral epiphysis). In this sign, the line of Klein passes above the femoral head 1. It is best seen on the frontal projection 2. On the AP view of a normal hip, the Klein line intersects a small portion of the lateral capital epiphysis.
Slipped upper femoral epiphysis - grading - Radiopaedia.org
Mar 31, 2024 · Grading of SUFE (slipped upper femoral epiphysis) can be made on both AP and true lateral projections. On an AP radiograph a line along the superior margin of the femoral neck (line of Klein) should intersect the lateral corner of the epiphysis. Slip is graded based on the displacement of the epiphysis in relation to the metaphysis 3:
Slipped upper femoral epiphysis - Radiopaedia.org
Oct 23, 2024 · On the AP, a line drawn up the lateral edge of the femoral neck (line of Klein) fails to intersect the epiphysis during the acute phase (Trethowan sign). The metaphysis is displaced laterally and therefore may not overlap the posterior lip of the acetabulum as it should normally (loss of triangular sign of Capener) 5.

Line of Klein describes a line along the superior edge of the neck of femur. The line should normally intersect the lateral part of the superior femoral epiphysis. In this case the right side is normal (blue line) whereas the left side demonstrates a slip (orange line).

The Klein line is drawn along the lateral aspect of the femoral neck and should intersect a portion of the lateral capital epiphysis. On the right, the green line indicates the normal appearance of the Klein line. On the left, the red line is abnormal and barely intersects the capital epiphysis.
