intertrochanteric line การใช้

• Just like the intertrochanteric crest on the posterior side of the femoral head, the intertrochanteric line marks the transition between the femoral neck and shaft.
• In some cases there is no division, and the ligament spreads out into a flat triangular band which is attached to the whole length of the intertrochanteric line.
• As a consequence, the capsule of the hip joint attaches in the region of the intertrochanteric line on the anterior side, but a finger away from the intertrochanteric crest on the posterior side of the head.
• The intermediate ridge or pectineal line is continued to the base of the lesser trochanter and gives attachment to the pectineus; the medial ridge is lost in the intertrochanteric line; between these two a portion of the iliacus is inserted.
• It surrounds the neck of the femur, and is attached, in front, to the intertrochanteric line; above, to the base of the neck; behind, to the neck, about 1.25 cm . above the intertrochanteric crest; below, to the lower part of the neck, close to the lesser trochanter.
• The vastus medialis and vastus intermedius appear to be inseparably united, but when the rectus femoris has been reflected a narrow interval will be observed extending upward from the medial border of the patella between the two muscles, and the separation may be continued as far as the lower part of the intertrochanteric line, where, however, the two muscles are frequently continuous.
