Flashcards in Adult Hip & DJD Deck (11):

Developmental causes of hip DJD (4)

DDH, Perthes disease, slipped capital femoral epiphysis, femoral-acetabular impingement (FAI)


Non-developmental causes of hip DJD (4)

Traumatic (dislocations / fractures), infection, inflammatory (RA), idiopathic


PE findings for hip DJD (3)

Restricted / painful hip ROM (esp IR and flexion contracture), weak hip abductors (Trendelenburg test), length discrepancy.


Imaging findings for hip DJD (4)

Loss of joint space, cysts in femoral head, sclerosis, and osteophytes


Where does hip pain radiate to?
Where does back pain radiate to?

Hip: knee
Back: butt and below the knee


Non-operative treatments for hip OA

NSAIDs, activity modification, PT, weight reduction, assist devices


Joint sparing surgeries for hip OA

Osteotomy and hip arthroscopy


Reconstructive surgeries for hip OA

•THA is the treatment of choice for hip DJD. Bone loss or joint wear may cause loosening of the joint and fracture. 80% of THA’s use polyethylene bearings.
•Surface Replacement Arthroplasty (SRA) = resurfacing. Joint is replaced w/ a metal-on-metal articulation w/ less bone removal than w/ THA. SRA is generally reserved for younger, high demand pxs.


Treating a femoral neck fracture in elderly vs younger pxs

•Elderly pxs – Treatment of choice is partial or total joint replacement
•Younger pxs – anatomic reduction and fracture fixation to avoid prosthetic replacement.


Treating intertrochanteric hip fracture

Save femoral head w/ pins due to better blood supply.


Goals prior to elective THA / TKA in obese pxs

Reduce BMI under 40, optimize nutrition, control blood sugar / HTN / cholesterol / sleep apnea / venous stasis.
