An introduction to the minimally invasive osteosynthesis of intra-articular calcaneal fractures

The approach to the treatment of intra-articular calcaneal fractures has often been the subject of discussion. The results achieved with both operative and non-operative management remain to some extent unpredictable. Minimally invasive osteosynthesis offers an alternative approach, especially in those cases in which open reduction would be hazardous and non-operative treatment inadequate. This technique requires minimal dissection and preserves subtalar motion almost completely. The authors believe that displaced intra-articular calcaneal fractures are best treated through operative intervention. Restoration of articular congruity is an integral, though not necessarily sufficient, component of a successful long-term outcome following calcaneal fracture. The extra-articular dimensions of the calcaneus must be restored in order to tolerate standard shoe-wear, maintain a functional range of talocalcaneal motion and avoid subsequent tibiotalar arthrosis. However, in certain circumstances open reduction may be associated with an unacceptably high complication rate. In these cases, the authors have found a minimally invasive osteosynthesis technique useful in dealing with competing goals. In our experience, this technique can, when used appropriately, result in a functional. recovery of the patient suffering a calcaneal fracture.
