118 cases with uper and median partialfibulectomy were reported in this paper. Of them50 cases were followed up 1～8 years. The clinicalfunction, foot arch and X-ray of bilaleral ankleswere examined. Ankle joint function was mea-sured with the instrument made by ourself. Afteranalysis and valuation of the results, our conclu-sion is that uper and median partial fibulectormydoes not affect the ankle joint function. Thereforethe fibula being considered as a donor bone is ac-ceptable.
