KTO Gamma Intramedullary Nail System

The gamma nail or trochanteric nail is an osteosynthetic implant designed to treat proximal femoral fractures in the trochanter area with a closed intramedullary fixation method.

A trapezoidal shape provides a press-fit in the metaphyseal region to position more material on the lateral side of the nail.

About The System

The KTO Sliding Compression Gamma IM Nail System consists of the following components: 

  • KTO Sliding Compression Gamma Nail Short/Long
  • KTO Sliding Compression Lag Screw Parent/Sub
  • 4.5mm Holding Type Double Thread Locking Screw
  • Locking End Cap / Normal End Cap


  • fractures of the femur including simple shaft fractures, comminuted shaft fractures, spiral shaft fractures, long oblique shaft fractures and segmental shaft fractures
  • subtrochanteric fractures
  • intertrochanteric fractures
  • ipsilateral femoral shaft/neck fractures
  • intracapsular fractures
  • non-unions and malunions
  • polytrauma and multiple fractures
  • prophylactic nailing of impending pathologic fractures
  • reconstruction, following tumor resection and grafting
  • bone lengthening and shortening


Anti-rotation to help preserve normal anatomy and biomechanics.

Trapezoidal nail profile provides enhanced stability in the proximal femur for early weight bearing.

5° lateral offset for minimally invasive trochanteric approach. 127° neck shaft angle suits Asian’s anatomy.

Compression actively maintained to help stability and union.

Preservation of femoral offset to aid a return to function.

Small proximal diameter preserves the gluteus medius tendon and the lateral wall of the greater trochanter.
