MR imaging of the hip abductors: normal anatomy and commonly encountered pathology at the
greater trochanter. Magn Reson Imaging Clin N Am.
The goals of this procedure are to create and abduction and extension effect in the femur at the level of the ischium to increase the range of abduction, support the femur on the pelvis, to reduce lumbar lordosis, and to prevent a Trendelenburg limp by tightening the gluteus medius muscle as the distance of the
greater trochanter from the pelvis is increased.
The correct entry point was the tip of the
greater trochanter in anteroposterior view, and along the Centre of the femoral canal in lateral view.
The latter is important because regional variations in bone quality, fracture risk, and therapy response are likely to exist within the proximal femur given that, for example, the femoral neck and
greater trochanter are the sites most likely to fracture.
To measure the distance between tip of
greater trochanter and centre of femoral head (in the line of femoral anteversion the greatest distance was taken), intra operatively.
Greater trochanter pain syndrome: a descriptive MR imaging study.
By analyzing all 40 lower limbs, we identified that the location of PH for the NEPs of PMB, GMB, ALMB, ABMB and AMMB were located at 76.41[+ or -]0.71 %, 93.85[+ or -]2.07 %, 92.05[+ or -]2.15 %, 80.75[+ or -]1.20 % and 88.08[+ or -]1.09 % respectively on line H from the
greater trochanter of femur.
She then underwent irrigation and debridement with
greater trochanter excision and hook plate removal (Figure 7).
Clinical examination showed limb abduction with internal rotation of the knee, mild pain, crepitus, limited range of motion during left hip manipulation, and a lack of palpable symmetry on the left side between the ischial tuberosity and the
greater trochanter. A blood sample was collected from the auricular vein, and the results of a complete blood count and serum biochemical profile were within normal ranges for the species.
Clinical investigation was preceded by anatomical analysis using the 3-dimensional human anatomy applications BioDigital Human (BioDigital Inc., New York, USA), Zygote Body (Zygote Media Group Inc., American Fork, USA), and Human Anatomy Atlas (Visible Body, Newton, USA), which revealed that both femoral and sciatic nerves potentially can be reached from the lateral surface of the thigh above the
greater trochanter. We assumed that both SNB and FNB can be performed from the single needle insertion point located at the junction of lower and middle third of distance between the
greater trochanter and iliac crest along the midaxillary line (Figure 1).
