    Study Notes

    Femoral Head Fracture

    • Trauma is the primary cause of femoral head fracture.

    Avascular Necrosis

    • Interruption of blood supply leads to avascular necrosis of the femoral head.

    Intrap Capsular Fracture

    • Fracture that occurs inside the capsule of the hip joint is called an intracapsular fracture.

    Subtrochanteric Fracture

    • The distinguishing feature of a subtrochanteric fracture is that it occurs in the proximal femoral shaft, within 5 cm of the lesser trochanter.

    Muscle Groups in Femoral Fractures

    • The gluteus medius and minimus muscle groups contribute to producing shortening and lateral rotation of the leg in femoral fractures.

    Spiral Fracture

    • A spiral fracture of the femoral shaft is characterized by a fracture line encircling the shaft like the stripes on a candy cane.

    Pillion Fracture

    • A Pillion fracture is a type of fracture that involves the medial wall of the acetabulum.

    Transverse Patellar Fracture

    • A transverse patellar fracture is caused by a forceful quadriceps contraction with the foot planted on the ground.

    Femoral Shaft Fracture

    • The iliacus muscle group is responsible for pulling the proximal fragment in a femoral shaft fracture.

    Foot Drop

    • Foot drop is caused by damage to the common peroneal nerve.

    Metatarsal Fracture

    • A fracture involving the 2nd, 3rd, 4th, and 5th metatarsal bones is commonly referred to as a Lisfranc fracture.

    Muscular Attachment

    • The iliac bone is devoid of any muscular attachment.
