Management of calcaneal fractures in adults. Conservative versus operative treatment.
Significant progress had been made in the management of calcaneal fractures. This is reflected in the marked decrease in complication rates associated with the current intervention of these potentially devastating injuries. The treatment priorities that are key to achieve best results in a displaced calcaneal fracture are an anatomic reconstruction of the entire calcaneus including articular surfaces, height, alignment, and length, with a function directed postoperative management. The value of these priorities is confirmed by long term followup results. Conservative treatment should be considered only in cases of extraarticular fractures, in cases of minor displaced intraarticular fractures in patients who are nonambulatory, and in cases where there is a clear contraindication for surgery. An anatomic reconstruction of an os calcis fracture is difficult to obtain. In two-part fractures, according to the classification described by Sanders et al, an anatomic reduction is obtainable in more than 80% of cases. However, if the articular cartilage damage that is typically present is considered, a 70% rate of good to excellent clinical results is more realistic. In three-part fractures, anatomic reduction is attainable in approximately 60% of cases with a 70% rate of good results. These two subgroups comprise approximately 90% of all calcaneal fractures. It has been put into practice recently to optimize the extended lateral approach using posteromedial and anterolateral windows, so that an anatomic reduction can be achieved in more than 60% of os calcis fractures considered as Type III according to the classification described by Sanders et al. Additional scientific work in this area of trauma orthopaedics would benefit most from a general consensus on a fracture classification system and on a clinical scoring system, with 5-year followup studies using these treatment methods and evaluation systems.
