OBJECTIVETo investigate the operative treatment of displaced intra-articular calcaneal fracture by lateral minimally invasive approach reduction and internal fixation.

METHODSDuring January 2006 to September 2009, 30 cases (31 feet) of displaced intra-articular calcaneal fracture were treated by open reduction and hollow screws internal fixation through lateral minimally invasive approach from the fibular tip to the basement of the fourth metatarsal foot (Sanders II in 21 feet, Sanders III in 8 feet, Sanders IV in 2 feet), including 23 males and 7 females with an average age of 36.5 years ranging from 18 to 60 years.

RESULTSThe 31 feet of 30 patients were followed-up for from 3 to 24 months (14 months in average). There was no soft tissue complications such as infected incision, skin necrosis, poor wound healing, and sural nerve injury. X-ray films of 25 feet after the operations showed well reduction of articular surface and satisfactory shape on calcaneal; 6 feet showed roughly normal shape. Based on the Maryland grading system, 6 feet were excellent, 20 feet good and 5 feet fair.

CONCLUSIONThe lateral minimally invasive approach is a good option for calcaneal fracture of Sanders II and III, because of its less damages to soft tissue and fewer complications. It could also provide excellent exposure of articular surface.
