The results of 39 comminuted femoral shaft fractures treated by intramedullarylocking nailing (29 Grosse-Kempf and 10 Brooker-Wills) were reviewed. Results were evaluatedaccording to Thorensen's criteria. With an average follow-up of 3.5 years (range, 2-8) resultswere excellent in 25 cases, good in 8 cases, fair in 5 and poor in one case. There were 6 caseswith intraoperative technical problems, 4 Grosse-Kempf and 2 Brooker-Wills nailings. Two ofthese patients had a delayed union and one developed a non-union. In the last 3 years, dynamizationwas not performed because there was no major difference in the rate of healing of thefracture and stability of the device with the use of static compared with dynamic interlockednailing. The Brooker-Wills nail insertion was easier than the Grosse Kempf, getting similarclinical results. In type IV fractures we recommended the static Grosse-Kempf nailing for itsbetter biomechanical properties in axial loading avoiding excessive shortening.
