Abstract

• Flexible intramedullary nailing has offered the many advantages in the treatment of the trochanteric fractures. But there has been many complications such as the knee joint pain, the deformity of external rotation of the femur, insufficient fixation of the fracture, peroneal nerve palsy, cortical breakage of insertion site of nailing and linear fracture of the femur.
  Of these complications, the cortical breakage and linear fractures of the femur was prevented by suing the Lownam clamp on the proximal site of insertion hole during the nailing.
  The authors have treated 31 cases of the trochanteric fractures with this method from March 1985 to December 1988 and the results are as follows:
  1. There was neither cortical breakage nor linear fracture at the site of insertion hole in all cases of 31.
  2. wide operation field was obtained with Lowman clamp by traction of muscles near by.
  3. The handle of Lowman clamp can be used as indicator to determine the grade of anteversion.
  4. It is confirmed that intramedullary nailing with Lowman clamp is simpler than conventional method and is highly recommended.
• Key words: Trochanteric fracture, Intramedullary nailing, Lowman Clamp
