Hip & thigh injuries Flashcards
(97 cards)
muscle strains - MOI
- explosive concentric contraction
- quick start/stop, change of direction
- eccentric contraction - lengthening; some muscles do two different actions simultaneously at two different joints
- overstretching
contributing factors: fatigue, pelvic asymmetry, strength imbalance, leg length discrepancy, muscle tightness
muscle strains can occur acutely or chronically, why?
-can become a chronic issue if there is no rest, during the repair process, scar tissue forms (creates a weak point in muscle)
muscle strains: S&S
- point tenderness with a palpable spasm
- possible palpable defect or divot
- bruising may or may not be present
- pain increases with AROM or IR testing
- PROM painful at end ROM when on stretch
- level of dysfunction or disability depends on severity of the injury
grade 1 muscle strain
minimal, few fibers torn, minor swelling
grade 2/3 muscle strain
complete rupture, more edema than grade 1
quadriceps muscle strain
- most common in rectus femoris
- possible avulsion fracture of AIIS
- vulnerable when hip extended and knee flexed
hamstrings muscle strain
- most commonly strained muscle in the body
- vulnerable with hip flexion and knee extension
- deceleration of leg swing
adductor muscle strains
- adductor longus most commonly injured
- adductor magnus presents similar to hamstring pain
hip flexor muscle strain
- sprinting or kicking MOI (unplanar movement)
- often tight due to seated posture
which special test is used to determine hip flexor muscle strains?
Thomas test (for hip flexors and quads) -looking to see where the quad is lying; someone with tight hip flexors will be above horizontal plane
initial management for muscle strain
- POLICE - tensor wrap/compression shorts, activity modification but early return to walk (want to engage muscle a bit; avoid intense activities)
- should not RTP until full ROM and strength - will feel a lot better before they actually have the strength needed to return
what types of therapy can be used to manage muscle strains after the initial treatment
- initially - gentle stretching, ROM and early contraction activation (isometric)
- address underlying causes (pelvis, muscle asymmetries)
- later - strengthening and functional exercises (eccentric and plyometric)
- testing in controlled environment before RTP
severe strain or rupture may require surgical intervention (grade 3)
quadriceps contusion MOI
direct blow to anterior or anterolateral thigh
-compression force between soft tissue and femur
S&S of quadriceps contusion
transitory loss of function/weakness and immediate bleeding; increased pain with AROM knee extension and hip flexion; PROM of knee flexion limited
which special test is used to diagnose quad contusion?
Ely’s test
-look at quad length; prone, bend person’s knee and see what happens at hip, if hip hikes up - tension in the quad; if hip is neutral, good length of quad
management of quad contusion
- POLICE - put the knee in max flexion and crutches - prevent stiffness, heal in length position
- therapy - gentle stretching and ROM (avoid soft tissue therapy - massage; RTP - pad and protect)
what is a secondary complication of a quadriceps contusion?
myositis ossificans
sciatica - def
any condition that causes irritation to the sciatic nerve including disk herniation in the low back, direct trauma (ex: hard fall), piriformis muscle compression
the sciatic nerve is a continuation of the _____ and travels through the _____
sacral plexus, greater sciatic notch
the sciatic nerve passes through the piriformis in ___% of the population
15
S&S of piriformis syndrome
- deep, dull ache in mid-buttock without pain
- numbness and tingling may extend down back of thigh and leg (further it travels down, the more severe it is considered)
- pain on palpation of sciatic notch/piriformis
- NEED to rule out disc herniation (straight leg raise test, coughing)
management of piriformis syndrome
- stretching, massage (trigger point or STRP - soft tissue release) (abduction, internal rotation)
- acupuncture has been known to provide relief from symptoms
hip dislocation MOI
- rare in sports
- traumatic force along the long axis of the femur when knee is flexed (MVA)
S&S of hip dislocation
-flexed, adducted, and internal rotated thigh
