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?
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.
