[Treatment of calcaneal interarticular fracture by open reduction and internal fixation].

OBJECTIVE: To investigate the clinical outcome of open reduction and internal fixation of calcaneal interarticular fractures.

METHODS: From August 1998, 38 calcanneal interarticular fractures in 35 cases, including 8 of type II, 14 of type III and 16 of type IV according to Sander's classification, were treated by open reduction to restore the posterior articular facet, subtalar facet, Bohler angle and Gissane's angle, following internal fixation by plastic titanic alloy plate. Thirty-three calcanneal interarticular fractures were followed up for 6 to 22 months, 12.3 months on average; and the healing time and joint function were evaluated according to Maryland Foot Score System.

RESULTS: The average healing time of fracture was 7.1 weeks, ranging from 5 to 12 weeks; and the joint function was excellent in 18 calcanneus, good in 13 calcanneus, and the satisfactory rate was 93.9%.

CONCLUSION: Open reduction and internal fixation with plastic titanium plate is a good choice for calcanel interarticular fractures.
