Pectineus

 

Anatomy

 

Origin:

  • Upper border of the pubis (super pubic ramis)

Insertion:

  • Below the lesser trochanter of the femur (Pectineal line of the femur which leads from the lesser trochanter to the linea aspera)



Major Arteries:

  • Obturator artery

 

Neural Innervation:

  • Femoral nerve

  • Obturator nerve (sometimes)

 

Trigger Points:

Physiology

 

Concentric Functions:

  • Hip adduction, transverse adduction & initial flexion

 

Eccentric Functions:

  • Decelerates hip flexion at heel strike during gait

 

Isometric Function:

  • Helps to dynamically stabilize the lumbo-pelvic hip complex along with the rest of the adductor complex
