Introduction
To reduce complications, a minimally invasive technique for the treatment of dislocated intraarticular fractures of the calcaneus
was used. Therefore previously described closed reduction and internal fixation techniques were combined and modified.
Materials and methods
Sixty-seven out of 92 calcaneal fractures could be retrospectively evaluated with an average follow-up time of 5.7 years (minimum
2–10 years follow-up). For radiographic evaluation, plain radiographs and CT scans were obtained. The Zwipp score was used
for clinical evaluation. Sanders type II, III and IV fractures were diagnosed.
Results
Length of surgery averaged 61 min (range 20–175 min). The incidence of subtalar arthritis was correlated to the severity of
fracture. Böhler’s angle was restored in 70.1% (47 of 67) of the cases. On the last follow-up evaluation the average Zwipp
score was 130 points (range 48–186 points). The majority (77.7%) of patients were content with their treatment result. The
rate of significant complications was 6.5%.
Discussion
Compared to open techniques the presented minimally invasive technique showed comparable results with a low rate of serious
complications and is a viable alternative for the treatment of intraarticular, dislocated calcaneal fractures.
