Structures of the Femur Proximal End of the Femur Head of femur (caput femoris): Spherical structure that articulates with the acetabulum of the pelvis to form the hip joint. Fovea of the head (fovea capitis femoris): Small pit on the medial surface of the femoral head where the ligament of the head of femur attaches. Neck of femur (collum femoris): Narrow region connecting the head to the shaft, commonly fractured in elderly individuals. Greater trochanter (trochanter major): Large lateral projection providing insertion for gluteus medius, gluteus minimus, piriformis, superior gemellus, inferior gemellus, and obturator internus. Trochanteric fossa (fossa trochanterica): Depression on the medial side of the greater trochanter where obturator externus inserts. Lesser trochanter (trochanter minor): Posteromedial projection for insertion of the iliopsoas muscle. Intertrochanteric line (linea intertrochanterica): Anterior ridge running between the greater and lesser trochanters; attachment site for the iliofemoral ligament and origin of vastus medialis and vastus lateralis. Intertrochanteric crest (crista intertrochanterica): Posterior ridge connecting the trochanters; contains the quadrate tubercle. Quadrate tubercle (tuberculum quadratum): Site of insertion for quadratus femoris muscle. Shaft of the Femur (Corpus femoris) Pectineal line (linea pectinea): Ridge on the posterior surface for insertion of pectineus muscle. Gluteal tuberosity (tuberositas glutea): Posterior surface ridge for insertion of gluteus maximus. Linea aspera (linea aspera): Prominent ridge running down the posterior shaft; composed of medial and lateral lips and an intermediate zone. Medial lip (labium mediale): Site for origin of vastus medialis, adductor longus, adductor brevis, and insertion of adductor magnus. Lateral lip (labium laterale): Site for origin of vastus lateralis, short head of biceps femoris, and lateral intermuscular septum. Intermediate zone (zona intermedia): Central part of linea aspera. Medial supracondylar line (linea supracondylaris medialis): Continuation of medial lip; attachment for adductor magnus. Lateral supracondylar line (linea supracondylaris lateralis): Continuation of lateral lip; origin of plantaris muscle. Anterior surface (facies anterior): Located between medial and lateral borders; origin of vastus intermedius. Posterior surface (facies posterior): Upper back surface of the shaft. Popliteal surface (facies poplitea): Triangular area on the posterior surface near the distal end. Medial surface (facies medialis): Located between anterior and medial borders. Lateral surface (facies lateralis): Located between anterior and lateral borders. Medial border (margo medialis): Separates medial and anterior surfaces. Lateral border (margo lateralis): Separates lateral and anterior surfaces. Distal End of the Femur Medial condyle (condylus medialis): Large, rounded medial projection for articulation with tibia. Lateral condyle (condylus lateralis): Large, rounded lateral projection also articulating with tibia. Medial epicondyle (epicondylus medialis): Prominence above the medial condyle; attachment site for tibial collateral ligament. Adductor tubercle (tuberculum adductorium): Located on medial epicondyle; insertion site for adductor magnus. Lateral epicondyle (epicondylus lateralis): Prominence above the lateral condyle; attachment site for fibular collateral ligament. Groove for popliteus (sulcus musculi poplitei): Small groove on lateral condyle for popliteus muscle tendon. Intercondylar fossa (fossa intercondylaris) Intercondylar line (linea intercondylaris) Patellar surface (facies patellaris): Smooth anterior surface between condyles that articulates with the patella. Clinical Notes Femoral neck fractures: Common in older adults, especially postmenopausal women; can compromise blood supply. Supracondylar fractures: Common in pediatric populations; can damage neurovascular structures. Hip flexor injuries: Involving the lesser trochanter and iliopsoas tendon. Sources: Kozlowski, T.
