What might be found on an x-ray of the patient in the previous question?
Displacement of pubic symphysis
Disruption of Shenton's line
Fracture of the coccyx
Disruption of Fenton's line
Displacement of the femoral head
What is a potential complication of the injury sustained by the patient in the previous question?
Permanent external rotation of the hip
Vascular necrosis of the femoral head
Disruption of blood supply to the feet
Permanent pins and needles in the gluteal region
Loss of ability to flex the knee in the affected leg

1. Vertical line through the lowest point of the iliac crest 2. Horizontal line midway between the ischial tuberosity and the lowest point of the iliac crest
1. Vertical line through the highest point of the iliac crest 2. Line from ASIS to the greater trochanter
1. Vertical line through the highest point of the iliac crest 2. Line from PSIS to the greater trochanter
1. Vertical line through the lowest point of the iliac crest 2. Line from PSIS to the lesser trochanter
Which nerve is at risk from an incorrectly performed intramuscular injection in the gluteal region?
A patient has paralysis of their femoral nerve. Which compartment of the thigh does this affect? Which movements will therefore be affected/impaired?
