Anatomy of the Thigh
Review
Nerve and Blood Supply
 Tibial and common peroneal nerves

Arise from the sacral plexus to form the largest
nerve in the body, the sciatic nerve
 The main arteries of the thigh include:

Deep circumflex, deep femoral, and femoral
 The two main veins of the thigh include:

Great saphenous and femoral
Muscles
 Fascia lata femoris



Deep fascia that surrounds thigh musculature
Thick anteriorly, laterally, and posteriorly
Thin on the medial side
 IT-band

Attachment site for the tensor fascia lata and
gluteus maximum
Quadriceps
 Insertion at proximal patella via common
tendon

Pre-patellar tendon
 Rectus femoris = bi-articulate muscle
 Only quad muscle that also crosses the hip
 Extends knee and flexes the hip
 Important: distinguish between knee
extensors and hip flexors


Injury evaluation
Treatment and rehabilitation programs
Hamstrings
 Cross the knee joint posteriorly
 All hamstrings, except the short of head of the
biceps femoris, are bi-articulate


Crosses the hip joint as well
Forces dependent upon position of both knee and hip
 Important: distinguish between knee flexors and hip
extensors

Exercises for the core must also be included
 Develop functional strength and dynamic stabilization
Rehabilitation Techniques
 Neuromuscular Control
 Established through postural alignment and stability
strength
 As neuromuscular control is enhanced, the ability of
the kinetic chain to maintain appropriate forces and
dynamic stabilization increases
 Focus on balance and closed kinetic chain activities
Functional Progression and Return
to Activity
 Begin in pool, non-weight bearing
 Progression of walking, to jogging, to running,
and to more difficult agility tasks
 Before returning to play, athlete should
demonstrate pain free function, full ROM,
strength, balance, and agility
