A- extends thighs at hip joint and flexes knee
N- sciatic nerve

16

Describe muscle fibres

Type1 red Fibres ( slow twitch fibres). Small diameter, more blood vessels and myoglobin, better suited to slow and prolonged contractions.
Type2 white fibres ( fast twitch fibres) Are larger in size, have fewer blood vessels and lower myoglobin content and are capable of powerful contractions of short durations

17

Indications for trauma and pain in the athlete

-evaluate for muscle, tendon, bursal pathology and for hernias
-apophyseal avulsions in adolescents

18

-tendinopathic gluteal insertions

19

Indications for snapping, clicking or locking hip

-bursal pathology
-capsular thickening

24

Indications for infection

-joint effusion
_capsular thickening

25

Clinical test/ patient symptoms

Pain when kicking- iliopsoas or rectus femoris strain
Pain twisting- adductor muscle strain
Pain with sit ups- rectus abdominus injury or hernia
Hip pain associated with lis back or buttock pain - referred from lumbar spine, sacroiliac joint or tho rich-lumbar junction
Rheumatoid arthritis- joint effusions
Snapping hip syndrome-painful, audible snap anteriorly during hip motion
Iliotibial band syndrome- painful snap laterally over greater trochante

26

Superficial ring?

The superficial ring can be identified just medial and superficial to the lateral margin of the pubic tubercle. The ingiunal canal runs obliquely towards the ASIS

27

Deep ring?

The deep ring can be identified superior and lateral to the origin of the inferior epigrastric artery from the terminal portion of the external iliac artery before it passes under the ingiunal ligament

28

The femoral canal?

The femoral canal is approximately 2 cm proximal to the SFJ, just inferior to the ingiunal ligament

29

Joint effusions

-common finding in patient with hip pain
