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.
