Description

Greater Trochanter

Bursa

  • Subgluteus maximus bursa
    • Lateral to the greater trochanter, between the tendons of gluteus maximus and medius
    • Sometimes divided into up to 4 seperate bursa
    • Deep subgluteus maximus bursa: largest, most consistent of these subdivisions, often referred to as the “trochanteric bursa”, implicated in Greater Trochanteric Pain Syndrome
    • Other components include secondary deep, superficial, gluteofemoral
  • Subgluteus medius bursa
    • Up to 3 bursa, largest on anterior surface of greater trochanter
  • Gluteus minimus bursa
    • Minor bursa, deep to the minimus insertion on the anterior aspect of the greater trochanter.

Trochlear Groove

  • Partially responsible for stabilizing patella during knee flexion and extension

Other Structures

  • Peritrochanteric Compartment
    • Contents: "trochanteric bursa"
    • Anterior border: proximal Sartorious, Tensor Fascia Latae
    • Medial border: Gluteus Medius, Gluteus Minimus
    • Lateral border: fibers of Iliotibial Band
    • Inferior border: terminates at the level of the gluteal sling insertion
    • Clinical significance: Portal for hip arthroscopy
  • Lateral Compartment
  • Peripheral compartment
