ENDERNAIL
 

Endernails- the reliable, time-tested option for treatment of pertrochanteric and subtrochanteric fractures in elderly patients.

The Problem

Subtrochanteric and pertrochanteric femoral fractures are frequently observed in elderly patients. In the treatment of these fractures the surgeon is confronted not only with the problems owing to the patient's age, but also with the structural/mechanical problem of obtaining an adequate osteosynthesis within the shortest possible time. A treatment method is therefore necessary which takes the patient's weakened physical condition into consideration and which, at the same time, allows an early mobilization. These requirements must also be met in the event of difficult or unstable fractures, for instance in comminuted fractures.

The Solution

In 1970, Dr. Ender established a surgical method which satisfies the various requirements:

  1. The risk of infection is lowered by approaching via a small incision remote from the fracture site.
  2. The small operating area and a reduction in the loss of blood are beneficial mainly to the elderly patients.
  3. The high strength of the Endernails guarantees immediate postoperative load stability in a high percentage of the cases.
  4. The individual curvature of the Endernails allows a closed resetting of severely displaced fragments.
  5. High stability is guaranteed by the Endernailing even in complicated and unstable fractures (e.g. comminuted fractures)
  6. Owing to the arrangement of the Endernails on the medial side of the medullary cavity, there is very little bending stress on the nails thus stabilizing the fracture site without breaking until callus healing sets in.
