Study Notes
Lower Extremity: Hip Complex - Posterior Hip
- Palpate the PSIS (Posterior Superior Iliac Spine) and sacral hiatus.
- Start laterally and cranially on the iliac crest, moving inferiorly to identify the PSIS.
- Track the iliac crest's downward curve to the PSIS.
- Draw a line from the PSIS midpoint to the sacral hiatus, labeling this line "A". Divide line A into thirds.
- Palpate for the sacral hiatus, then the sacral horns (cornua sacralis).
- The S2 spinal process is variable in size, use your finger to find it. Follow the midline to the sacral hiatus.
- Palpate the greater trochanter.
- Locate the iliac crest midpoint, and palpate inferiorly for the greater trochanter.
- Confirm location by passively flexing the knee to 90 degrees and rotating the femur. If on the trochanter, you will feel the bone movement.
- Draw a line from the greater trochanter's cranial aspect midpoint to the PSIS midpoint, labeling this line "B". Dividing line B into thirds.
- Draw another line from the cranial aspect of the greater trochanter to the anterior 2/3 of line A, labeling this line "C". Divide line C into thirds.
- The triangle formed by the upper two thirds of line A, line B, and line C represent the location of the piriformis muscle.
Lower Extremity: Hip Complex - Medial Femoral Triangle
- Borders:
- Base: Inguinal ligament
- Lateral: Sartorius
- Medial: Adductor longus
- Locate the ASIS (Anterior Superior Iliac Spine) by palpating the iliac crest, moving from posterior lateral to anterior medial until you encounter a bony prominence.
- Palpate from the umbilicus caudally to locate the pubic tubercle.
- The inguinal ligament runs between the pubic tubercle and ASIS, thicker at the ASIS and thinner towards the pubic tubercle.
- Identify the sartorius muscle, forming the lateral leg of the medial femoral triangle.
Lower Extremity: Hip Complex - Lateral Femoral Triangle
- Borders:
- Base: Rectus femoris
- Lateral: Tensor fascia lata (TFL)
- Medial: Sartorius
- Location the Tensor fascia lata (TFL) which is the lateral leg of the triangle.
- Find the ASIS (Anterior Superior Iliac Spine) and find the internal rotation from posterior to superior of the greater trochanter.
- Locate the rectus femoris, which forms the floor of the triangle
- Ask the patient to extend their knee and locate to the Attachment of rectus femoris at the AIIS (anterior inferior iliac spine.)
Lower Extremity: Hip Complex - Gluteal Fold
- Palpate the ischial tuberosity in the region of the gluteal fold.
- Note the relationship of the ischial tuberosity to the greater trochanter.
- The hamstrings (except the short head of the biceps femoris) attach to the proximal lateral border of the ischial tuberosity.
Lower Extremity: Hip Complex - Hip Adductors
- Adductor longus:
- Palpate the tendon and muscle at the pubic tubercle while the patient performs isometric hip adduction.
