Objective To explore the more convenient and more efficient operation methods in correcting soft tissue defects in buttock and lowes extremity. Methods From Oct. 1997 to Jun. 2001, medical polyacrylamide hydrogel was used to treat 33 cases with sunken greater trochanter or flat buttocks as well as 26 cases with soft tissue deformities in the lower extremity. Results Follow-up for 2 to 34 months proved that among all these 59 cases, except one case occurred some orange peel appearance of skin in the injected area, and one case had to have the gel drawn out due to acute inflammation in the leg after filling, all other cases achieved satisfactory effects. Conclusion In correcting the soft tissue deformities of buttock or lower extremity, ,medical polyacrylamide hydrogel serves as an ideal soft tissue filler. It is easy to operate while the shapes are easy to control. The effects are good and stable.
