Abstract
The purpose of the study was to perform an independent assessment of the results of open reduction and internal fixation (ORIF) on a selected group of displaced intra-articular calcaneal fractures from two centres.
It still remains controversial whether to manage intraarticular calcaneal fractures conservatively or operatively with few long-term results. The identification of patients who may benefit from the procedure is still undecided.
Fifty fractures in 46 patients with a defined significant displacement of an intra-articular fracture of the calcaneum underwent ORIF by one of the two senior authors. Mean age at operation was 46 years and mean follow-up was 44 months. 88% of the injuries were due to a fall from a height. 30% of the patients had contralateral foot/ankle injuries, and 20% of the patients developed a superficial wound infection. The infection rate was significantly higher in patients whose surgery was delayed more than 14 days.
All patients were independently reviewed after a minimum two-year follow-up. A clinical, radiographic and subjective assessment of the outcome was made. The results were correlated to the original fracture type. The mean Atkins score was 88 (out of 100). Bilateral injuries fared worse. Heel pain at follow-up correlated with a poor score. Atkins scores over 90 occurred in 77% of Saunders Type II, 50% in Type III, and 43% in Type IV fractures. 94% returned to work at a mean of 10 months post-injury. Three patients have undergone a subtalar arthrodesis – two for persistent pain and one for a significant malunion. One patient required a flap but there have been no cases of chronic osteomyelitis.
In patients with significantly displaced fractures, ORIF is a worthwhile procedure with 90% of patients satisfied and 94% returning to work. Gross articular comminution does not preclude a good/excellent result if hindfoot alignment is restored. ORIF after fourteen days should be avoided due to the high risk of infection.
