Harris Hip Score Flow

Harris Hip Score flow


The Harris Hip Scale (HHS) was developed for the assessment of the results of hip surgery, and is intended to evaluate various hip disabilities and methods of treatment in an adult population. The original version was published 1969[1]. The HHS is an outcome measure administered by a qualified health care professional, such as a physician or a physical therapist.

The Harris Hip Score flow contains the Harris Hip Score questionnaire and associated calculation. After form submission, the Harris Hip Score calculation is executed automatically. It's easy to extend this flow with conditional logic based on the interpretation of the Harris Hip Score calculation.

Questions and Scoring

There are ten items covering four domains. The domains are pain, function, absence of deformity, and range of motion[2].

The pain domain measures pain severity and its effect on activities and need for pain medication. The function domain is divided into daily activities and gait. The deformity domains observes hip flexion, adduction, internal rotation, and extremity length discrepancy while the range of motion domain asses hip ROM.

The HHS is a measure of dysfunction so the higher the score, the better the outcome for the individual. The maximum score possible is 100, the lowest possible score is 0.
