Orthopedic Procedures- Hip Flashcards

1
Q

Positive ortolani’s test

A

Developmental dysplasia of the hip

Elevation and abduction of femur relocates a dislocated hip- reducible

Q

Developmental Dysplasia of Hip- desciption, risk factors, diagnosis

A

Abnormal development or dislocation of the hip secondary to capsular laxity and mechanical factors- hip is forming outside the acetabulum, capsular laxity caused hip to push out and forms the head of femur outside the acetabulum

RFs- breech positioning, family history, female, first born child
Related problems- commonly associated with ‘packaging problems’ like torticollis, metatarsus adductus

Ultrasound is better for diagnosis, because femur is not always ossified yet

Q

DDH treatment

A

Achieving and maintains early,concentric reduction: Pavlik harness, closed and open reduction, various osteotomies, spika cast

Q

SCFE- what is it, presents like, treatment

A

Disorder of the proximal femoral epiphysis- slip through growth plate, femoral head remains in the acetabulum, the neck is displaced anteriorly and externally rotates
adolescents, African american, obese

Present with- limp, externally rotated gait, obligatory hip external rotation when try to flex, decreased hip internal rotation, hip/thigh/knee pain (obturator nerve comes around, can get irritated, feel pain in the knee)

Percutaneous pinning

Q

Femoral shaft fracture- associations and treatment

A

Very high energy injury: Usually associated with other injuries- other fractures (neck of femur), visceral insults, etc (need a COMPLETE physical exam/X-rays)

Restore limb length, restore alignment, restore rotation
Intramedullary nail for most- can fix all 3 of these goals

Q

Avascular necrosis of femoral head- causes, presents with, testing, treatment

A

Osteonecrosis, intramuscular coagulation/arterial occlusion
Many causes of avascular necrosis** number 1 is idiopathic
Usually have a clotting abnormality, hypercoagulation, sickle cell, alcoholism, high doses of prednisone, etc.

Groin pain, X-rays/MRI: can see early stages on MRI, eventually see femoral head irregularity/collapse/sclerosis/cartilage collapse

Bisphosphonates or anti-coagulatants
Core decompression (before collapse)- surgery where drill side of femoral head, scrape out dead bone, put cement/bone graft
Rotational osteotomy- cut femoral head, put screws in, gives area of femoral area a different place to put load on
Vascularized fibular strut grafting- take dead bone out, take fibula arterial supply and plug into femur to heal
Hip arthroplasty- done after actual structural collapse

Q

Greater Trochanteric Bursitis- cause, presents, RF’s, treatment

A

IT band can get tight and rub on bursa to cause pain
Pain over greater trochanter, pain may be worse at night, when lying on affected hip, when getting up from chair after sitting for awhile

RF’s- women, middle aged, elderly, repetitive stress injury, hip injury/contusion, spine diseases, leg-length inequality affecting gait, RA, previous surgery

Diagnose with palpation

Treat with activity modification, antiinflammatories, ice,crutches, PT, or lastly, cortisone injection

Q

Osteoarthritis symptoms, exam, X-ray

A

Stiffness in hip, pain ‘flares’, groin pain, limp, usually point to pain anteriorly

Decreased ROM, internal rotation most often restricted by osteophytes (obligatory external rotation when flexed), limp, reproducible groin pain

Joint height narrowing, sclerosis, cystic formation, osteophytes
