Pinless calcaneus traction: a preliminary report

Calcaneus traction with a Steinmann-pin or K-wire inserted into the dorsal aspect of the calcaneus is a common temporary procedure in fractures of the lower leg when internal fixation has to be delayed. Infection due to this simple manoeuvre is rare, but is a very serious complication. In 1991, a so-called pinless external fixator was introduced in clinical trials, based on the idea of external fixation without transosseus pins, thus preserving local blood supply and lowering the risk of pin track infection. This pinless clamp also represents a handy tool for calcaneus traction. We have used this pinless clamp for calcaneus traction in 39 patients without any major problems or complications. Of these, 29 patients were scheduled for delayed internal fixation, and in 10 patients this clamp was used intraoperatively in closed tibial nailing for traction on the fracture table. Tips and tricks for the use of this pinless clamp, and its advantages and disadvantages are discussed.
