We present 50 femoral shaft fractures treated by Grosse-Kempf intramedullary
nailing. A retrospective study was performed by using the Thorensen scale for the evaluation of
results. This scale takes into account different parameters such as radiological malposition, range
of motion of the knee, shortening of the femur, pain, and swelling. Twenty months after treatment
(range: 12-27), the results were excellent in 32 cases, good in 13, fair in 4 and poor in one.
Grosse-Kempf nailing seems to be a good method for treating this type of fractures, particularly
in conminuted fractures localized in the 2, 3, 4 and 5 Wiss's zones. The majority of fair and poor
results are caused by errors in the surgical technique.
