Plica
- piece of fibrous tissue extending from the joint capsule that is supposed to reabsorb during growth & development
- fibres get in way of joint mimicking a meniscus injury
Key structures of the hip and pelvis
- illiac crest
- ASIS
- AIIS
- PSIS
- ischial tuberosity
- pubic symphysis
- hip joint and articular cartilage
Origin of sartorius
- ASIS
Origin of rectus femoris
- AIIS
Origin of hamstrings
- ischial tuberosity
External obliques origin
- outer surface of ribs 5-12
External obliques insertion
- inferiorly onto anterior 1/2 of iliac crest and medially into linea alba
External obliques action
- trunk rotation
- flexion
- side bending
- compresses abdominal viscera
What are the hip flexors?
- psoas
- iliacus
- sartorius
- rectus femoris
- pectineus
- tensor fascia latae
Which structures insert into top of illiotibial band (IT)?
- glute max
- tensor fascia latae
Importance of rectus femoris
- palpation point
- only quad muscle that also does hip flexion
Insertion of quad muscles
- quad tendon into patella
Action of all quad muscles
- knee extension
Adductors
- pectineus
- adductor longus
- adductor magnus
- adductor brevis
- gracillis
Insertion of sartorius
- medial aspect of prox tibia
What is the acetabular labrum
- fibrous cartilage that rims the acetabulum
Role of the acetabular labrum
- deepens socket
- increase stability of joint
Blood supply of acetabular labrum
- base that attaches to bone has some capacity to heal due to blood supply from bone
- free edge has limited blood supply so doesnt heal well
What is a hip pointer?
- contusion of iliac crest (periosteum has lots of sensory nerves)
MOI of hip pointer
- blunt trauma to iliac crest
Signs and symptoms of hip pointer
- severe pain with trunk flexion, rotation, side bending or hip flexion
- bruising
- swelling
- muscle spasm
What other structures may be affected with a hip pointer?
- external obliques
- tensor fascia latae
What else do athletes usually report pain with when they have a hip pointer?
- forced exhalation
- bowel movements
- all functions of external obliques
Acute management of hip pointer
- PIER
- lymph drainage to settle spasm
- donut pad with cover for RTP
