Cited researchers assessed mainly the union of fractured bone fragments, and did not discuss functional results, Functional treatment for fractures of the shaft of femurs yielded even better results. Comparison of the results reported in this paper with those reported by others are also difficult because of different criteria of evaluation. Of evaluation. Hsien-Chin et al9. Observed complete healing in all 93 patients treated conservatively. Brown and Preston2 reported complete healing in 76 patients, but there was 10.5% poor results caused by shortening of the extremity and improper elongation. Dencker6 treated 46 patients with fractures surgically and reported 9% poor results. Della Torre et al.5 did not achieve the union of bone fragments in 4.7% of 54 cases. Carpenter3 reported 3% poor results. Pielinski11 reported poor results in 10% of 80 cases.
