Bone
Femur
Thigh bone — longest, strongest bone
High-yield
Femoral neck fracture in the elderly risks avascular necrosis of the head (medial femoral circumflex artery supply).
Overview
The longest and strongest bone in the body, transmitting body weight from the hip to the knee. Its neck is a common fracture site in the elderly.
Reference facts
- Bone type
Long
- Key landmarks
Head with fovea; Neck; Greater and lesser trochanters; Intertrochanteric line and crest; Linea aspera; Gluteal tuberosity; Medial and lateral condyles and epicondyles; Adductor tubercle; Intercondylar fossa
- Articulations
Hip bone (hip joint); Tibia and patella (knee joint)
Clinical correlation
Intracapsular femoral neck fractures threaten the head's blood supply; extracapsular ones generally do not.
