Abstract:

Purpose

We report a new operative method for the treatment of the displaced intraarticular calcaneal fractures using minimal invasive internal fixation and external fixator after arthroscopic reduction.

Materials And Methods

From April 1999 to October 2013, We had performed the arthroscopic reduction and external fixation method for 45 patients(48 cases) who suffered from the calcaneal fractures involving the subtalar joint. We have excluded the cases that were not able to be compared with normal side due to affection to both sides. 35 patients (35 cases) were selected and followed up for 1 year or more. As to the assessment of clinical results, AOFAS score system was applied, and the restoration degree of posterior facet, calcaneal height, calcaneal width, and Bohler angle were measured by executing simple radiographs and the computerized tomograms pre- , post-operation and at the time of final follow-up.

Results

Average pre- and post- operation Bohler angle was increased 4.5° to 26.0° and was shown to be 25.3 ° on an average at the final follow-up. The posterior facet was restored to 2mm or less in whole cases and the calcaneal height index was restored form average pre-operative 86 to average 98 at the final follow-up. The calcaneal width index was also restored from average pre-operative 145 to average 110 at the final follow-up. Assessment by the AOFAS system showed an excellent group of 12 cases, a good group of 20 cases and a fare group of 5 which indicates that 91.4%(32 cases) of all showed a good scale or higher.

Conclusion

We obtained satisfactory radiographic and clinical results using minimal invasive internal fixation and external fixator after arthroscopic reduction of intraarticular calcaneal fractures. In this context, the operation method is considered as one of most effective treatment of the displaced intraarticular calcaneal fracture.
