Rating Scales of Smith et al for an Adult with Congenital Dislocation of the Hip

Smith et al rated clinical and radiologic findings in adults with congenital hip dysplasia. The authors are from the University of Michigan.

Rating scales:

(1) subjective symptoms

(2) objective findings

(3) radiologic rating of the position of the femoral head and neck relative to the acetabulum

(4) radiologic rating for the arthritis

(5) radiologic rating of the femoral head

Parameter	Finding	Rating
subjective symptoms	no complaint or minimal discomfort with strenuous use	1
	pain that is frequent or severe enough to interfere with ordinary activities	2
	severe and/or constant pain, incapacitating	3
objective findings	normal range of motion and no limp	1
	moderate loss in range of motion	2
	ankylosis or subtotal ankylosis	3
femoral head and neck	normal	1
	subluxation	2
	completely out of the true acetabulum	3
arthritis	no evidence	1
	mild or early degenerative changes	2
	severe changes (complete loss of cartilage, cysts, sclerosis, ostephytes)	3
femoral head	normal or near normal	1
	coxa magnum	2
	markedly flattened, irregular	3

where:

• Coxa magnum = broadening of the femoral head and neck
