概要	Limb‐sparing surgery may be considered for the treatment of soft-tissue sarcoma even when resection of a major neurovascular bundle is necessary to achieve a satisfactory surgical margin1,2. Function of an upper extremity with loss of one major nerve is often superior to function with use of a prosthesis after amputation3. In the lower extremity, limb‐sparing surgery may be considered even when the sciatic nerve must be resected because of tumor involvement. Resection of the sciatic nerve results in a sensory loss distal to the knee and motor dysfunction of the knee, foot, and ankle. However, an analysis of functional loss after sciatic nerve resection for the treatment of soft-tissue sarcoma has been reported only once to our knowledge4. We treated two patients with a soft-tissue sarcoma with a limb‐sparing procedure that included resection of the sciatic nerve. During rehabilitation, both patients walked very slowly with excessive lateral displacement of the trunk along the line of progression. Very slight improvement in their gait was noted at the two and five-year follow‐up examinations. We assessed walking function and gait characteristics of the two patients with use of a nonparametric objective evaluation system and a subjective gait analysis technique to obtain quantitative measures of functional loss5‐8. The results were compared with those of patients with a hip disarticulation who used a prosthesis and with the findings in healthy individuals.
