Description

Hip Flexor muscles

Hip flexor muscles

Name

• Hip Flexors
• Hip flexor muscles
• Hip flexor muscle group
• Flexors of the hip
• Anterior hip muscles
• Hip flexor complex

Main Hip Flexors

• Iliopsoas
  • Psoas (Major and Minor)
  • Iliacus
• Rectus Femoris

Weak Hip Flexors

• Iliocapsularis
• Sartorius
• Pectineus
• Tensor Fascia Latae
• Adductor Longus
• Adductor Brevis

Function

• Flexion of the thigh at the hip joint
• Allows movements such as:
  • Walking
  • Running
  • Climbing stairs
  • Kicking
• Iliopsoas provides the strongest hip flexion
• Contributes to pelvic stabilization during gait
• Assists with postural control of the trunk and pelvis

Innervation

• Primarily supplied by nerves from the Lumbar Plexus
• Individual muscle innervation
  • Psoas major: L1–L3 ventral rami
  • Iliacus: Femoral Nerve
  • Rectus femoris: Femoral Nerve
  • Sartorius: Femoral Nerve
  • Tensor fasciae latae: Superior Gluteal Nerve
  • Pectineus: Femoral Nerve

Vascular Supply

• Primary blood supply from branches of the:
  • Femoral Artery
  • Deep Femoral Artery
• Additional contributions from:
  • Medial Circumflex Femoral Artery
  • Lateral Circumflex Femoral Artery
