OBJECTIVETo study the curative effects of close nail-pry reduction and internal fixation with hollow screws for treatment of linguiform calcaneus fracture.

METHODSFrom May 2006 to October 2009,32 patients (35 feet) with linguiform calcaneus fracture were treated by close nail-pry reduction and internal fixation with hollow screws, including 23 males and 9 females ranging in age from 25 to 46 years, with a mean of 37.6 years. According to Paley classification, 3 cases were Paley II a, and 29 cases were Paley II b. All cases were close fractures. The time from injury to operation was 3 to 10 days after most swelling subsided. Böhler angle and Gissane angle were measured by X-ray before and after operation. The therapeutic effect was assessed according to ZHANG Tie-liang's foot score.

RESULTSAll the patients were followed-up for 6 to 18 months, with a mean of 12 months. All fractures gained bone healing. The time of fracture healing averaged 12 months. The fractures healed completely and no infection occurred. According to ZHANG Tie-liang's foot scale, the postoperative function was excellent in 18 feet, good in 10 feet, moderate in 5 feet and poor in 2 feet. The Böhler angle and Gissane angle were significant improved after treatment (P < 0.01).

CONCLUSIONThe surgical method of close nail-pry reduction and internal fixation with hollow screws for treatment of linguiform calcaneus fracture can regain the foot function, with minimal injury, fewer complications, earlier recovery and lower costs.
