Lower Extremity Sports Injuries Flashcards
What are 9 specific injuries to the pelvis, hip and thigh?
- pelvic apophysitis
- pelvic avulsion fractures
- snapping hip syndrome
- femoral stress fracture
- femoral acetabular impingement/labral tears
- muscle strains
traumatic hip dislocation - slipped capital femoral epiphysis
- Legg-Calve Perthes disease
What is the weakest point in the muscle-tendon unit of a growing athlete?
pelvic apophyses
Why do pelvic apophyses tend to occur?
bone growth exceeds the ability of the muscle tissue to sufficiently lengthen and stretch, thus increasing tensile forces which leads to microtrauma and progressive weakness and inflammation
What the 3 most common sites for pelvic apophysitis?
- ASIS
- AIIS
- ischial tuberosity
ASIS apophysitis occurs because what 2 muscles are pulling?
- Sartorius
- TFL
AIIS apophysitis occurs because what muscle is pulling?
rectus femoris
Between what ages do both the ASIS and AIIS apophyses ossify?
14-16
Ischial tuberosity apophysitis occurs because what muscle group is pulling?
hamstrings
Between what ages does the ischial tuberosity ossify?
21-25
What are 3 other less common apophysitis sites?
- lesser trochanter
- greater trochanter
- iliac crest
What are the symptoms of pelvic apophysitis?
well-localized, dull pain with activity at the involved location
What can be done to reproduce the athleteās symptoms?
tensioning of the muscle
What is the treatment for pelvic apophysitis?
rest, WBAT as long as there is no antalgic gait.
Once pain is controlled focus on muscle flexibility, ROM, and strengthening of the lumbopelvic and LE musculature
Return to sport following pelvic apophysitis is dependent upon symptoms and may take up to _ weeks
6
When do pelvic avulsion fractures tend to occur?
with the progression of an unmanaged apophysitis in the pelvis
What ages do pelvic avulsion fractures tend to occur the most?
adolescents ages 14-25 years
What are the signs and symptoms of a pelvic avulsion fracture?
- sudden āpopā
- tenderness and swelling
- painful WB resulting in antalgic gait
- associated bruising
What determines the treatment of pelvic avulsion fractures?
the degree of widening and displacement of the apophysis:
- less than 2 cm = conservative
- greater than 2 cm = surgical ORIF
Describe conservative treatment for pelvic avulsion fractures
relative rest from activity for 3 weeks followed by focus on regaining ROM, short course of muscle strengthening, followed by return to sport activities around 6-8 weeks
What is snapping hip syndrome characterized by?
audible and/or palpable āpoppingā of the hip caused by tendons moving over bony prominences
In what type of athletes is snapping hip syndrome most frequently found?
- performing artists
- distance runners
- hurdlers
What are the 2 classifications of snapping hip?
- external
- internal
What causes external snapping hip syndrome?
the friction of the IT band and/or anterior aspect of the glute max passing over the greater trochanter
What are 2 other pathologies that may occur with repetitive external snapping?
- trochanteric bursitis
- damage to the glute med
