Acetabular labrum

-fibrous cartilage
-rims the acetabulum
-deepens the socket
-increases stability of joint

Perfectly

Blood supply of labrum

-base that attaches to bone has some capacity to heal from blood supply to bone
-free edge has limited blood supply so doesnt heal well

Acetabular labral tears MOI

-acute plant and twist
-hyperabduction
-overuse and degeneration

How well did you know this?

Not at all

Perfectly

Acetabular labral tears signs and symptoms

-pain
-clicking/catching
-decreased hip ROM
-audible pop/sensation

Special test for acetabular labral tear

-scouring test

C sign for acetabular labral tear

-if someone cups this area it may be because they have this injury

Acute management of acetabular labral tear

-ice -rest -pain management -correct mechanics -proprioception -refer for surgery if conservative treatment isnt working

Scouring test pros and cons

-highly sensitive -lacks specificity

What can scouring test look for

-hip labrum tears -capsulitis -osteochondral defects -acetabular defects -osteoarthritis -avascular necrosis -femoral acetabular impingement syndrome

What is femoral acetabular impingement syndrome

-irregular shape of one or both joint surfaces leading to labrum/cartilage tears

ITB friction syndrome MOI

-ITB friction over lateral femoral condyle 2 degrees to biomech causes -overuse condition from friction over lateral femoral condyle

What sports are ITB friction syndrome common in

-running or cycling

Acute management of ITB friction syndrome

-PIER -treat inflammation -check footwear and wear patterns -biomech assessment -winter walking is a common factor

Hip flexor tendonitis MOI

-overuse -repetitive flexion

What sports are hip flexor tendonitis common in

-cyclists -runners -dancers -gymnasts

Hip flexor tendonitis signs and symptoms

-pain with active and resisted hip flexion -stretch pain with passive hip extension -TOP affected tendon

Acute management of hip flexor tendonitis

-ice -rest/altered activity -correct mechanics in sport -hip flexor wrap

Strains of the hip and thigh

-hip flexors -quads -hamstrings -adductors

Hip flexor strain MOI

-forceful hip flexion -leg caught in hip extension

Quad strain MOI

-forceful quad contraction -hip extension with knee flexion

Hamstring strain MOI

-excessive hip flexion with extended knee -in sprinting: eccentric hams contraction in late stance phase

Adductors strain MOI

-quick cutting -spits type motion

Signs and symptoms of hip and thigh strains

-pull or pop sensation -weakness -bruising with grade 2 and 3

Acute management of hip and thigh strains

-PIER -pressure pad -educate -NWB -hip flexor wrap or adductor wrap for daily wear as needed -effleurage/lymph drainage

Thigh contusions MOI

-blunt trauma

Thigh contusions signs and symptoms

-discoloration -muscle weakness possible

What are thigh contusions at risk of

-myositis ossificans

Acute management of thigh contusions

-effleurage or lymph drainage -ice -no deep tissue massage -donut pad

Special test for IT band syndrome

-nobles test

Nobles test

-apply pressure at lateral epicondyle while patient flexes or extends the knee

Positive nobles test

-severe pain over lateral epicondyle

How to do resisted muscle test for psoas

-laying supine -hold leg 30 degrees upward -try to push leg into extension and they resist

How to do resisted muscle test for rectus femoris

-high sitting -try to pull leg down into hip extension and they try to flex it

How to test for short adductors vs long adductors

-short: knees bent, hands on knees -long: laying supine, hands on feet

How to isolate gluteus medius for muscle testing

-lay on side -externally rotate top foot -try to push leg into adduction while they try to abduct
