ABSTRACT
<p><b>OBJECTIVE</b>To study the curative effects of close nail-pry reduction and internal fixation with hollow screws for treatment of linguiform calcaneus fracture.</p><p><b>METHODS</b>From 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.</p><p><b>RESULTS</b>All 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).</p><p><b>CONCLUSION</b>The 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.</p>
