Sports Med 2 Flashcards
Avulsion fractures at the hip or pelvis are usually treated how>
Non-operably
Most common casue of a pelvic avulsion fracture?
-strong muscular contraction during sports activities in skeletally immature patients
Most common pelvic avulsion fracture sites?
ASIS (anterior superior illiac spine), AIIS, IT (Ischial tuberosity
Hip Laberal tear symptoms
Groin Pain, clicking and snapping of hip joint, limited range of motion of hip joint
THree types of femeroacetabular impingement
CAM, Pincer, Combined
Quadriceps and Hamstring tears?
Once you’ve had one you are prone to more because the muscle heals with scar tissue and not muscular tissue. Scar tissue is not as flexible
New treatment method for hamstring and quad tears?
Platelett rich plasma,,,plateletts have healing factors and growth factors which help with healing
Meniscus repair options>
non-operative, repair, remove (used to be done all the time) With arthroscopic surgery we can now do some repairs.
Anterior Cruciate Ligament causes
Deceleration, cutting, jumping
70% of ACL tera patients….
hear or feel a pop.
- often say they felt like their knee was being hyperextended
- walking is difficult
- knee swells within hours
What is the difference between the swelling time with ACL and meniscus
ACL swells within hours,
Meniscus take a few days
THis is because tendons have vasculature (ACL bleeds and you get hemiarthrosis.
women have increased risk of ACL injury
yes, why? muscle strength, hormonal influences, limb alignment, notch dimensions, ligament size
What is the most sensitive ACL test?
Lachman test- looks like the anterior drawer test, feel for end mark.
Most accurate radiological study for ACL tear
MRI, non-orthogonal plane with the knee externally rotated 15 degrees, identify associated meniscal/chondral injuries, collateral ligaments
Characteristic bone bruise pattern of ACL
Lateral Femoral Condyle (mid third) and post 1/3 of lateral tibial plateau….very sensitive…know
