We performed isokinetic knee testing to assess thigh muscle function in ten patients (12 legs) before and after mid-shaft femoral shortening averaging 46 mm (27 to 70). Tests were at angular velocities of 60 degrees/sec and 180 degrees/sec, and were performed preoperatively and after 3, 6, 12 and 24 months. Isokinetic tests at two years showed a significant reduction in muscle function in both quadriceps and hamstrings, but recovery of function was significantly better for the hamstrings. There was a linear relationship with correlation of r2 = 0.31 to 0.86 between loss of muscle force at two years and the magnitude of shortening. Long-term loss of muscle force should be expected after a mid-shaft shortening of the femur of more than 10%.

We performed bilateral femoral shortening operations on 15 skeletally mature patients (11 women and four men). Their mean height pre-operatively was 193.5 cm and they were shortened by 5 to 9 cm. We used a subtrochanteric Z-osteotomy with an AO condylar plate in 11 patients, and mid-diaphyseal osteotomy with an intramedullary locking nail in four. After an average follow-up of 8.1 years, isokinetic muscle testing showed that muscle strength was reduced bilaterally in five patients. The strength ratio between hamstrings and quadriceps muscles was normal in all those treated by subtrochanteric shortening; in those shortened at the mid-shaft the quadriceps was relatively weaker. The result was rated as excellent by 11 patients, very good by three, and good by one.

We analysed the results of 93 tibial shaft fractures treated with the Grosse-Kempf locked nail. Twenty-six fractures were comminuted, 19 were open grade I to II, and 54 were located outside the middle third of the tibia. The deep infection rate was 3.2%. There were only two poor results. The use of this method is recommended and discussed.
