Management of calcaneus fractures by a new "Below-the-ankle" ilizarov frame: A series of 10 cases.

BACKGROUND

The optimal management of intra-articular calcaneal fractures is still controversial. Open reduction and internal fixation are always associated with serious complications.

AIM: Various alternative methods have been used with variable effects. This retrospective study aimed to analyze the clinical efficacy and safety of a new "below-the-ankle" Ilizarov frame in patients with calcaneal fractures caused by high-energy trauma.

PATIENTS AND

METHODS

We retrospectively explored ten patients with calcaneal fractures, of which four, five, and one were Sanders type II, III, and IV, respectively. All fractures were caused by high-energy trauma and were followed up for an average period of 21 months (range: 9-29 months). Clinical outcomes were primarily assessed by radiological criteria, functional scores of the foot and ankle, rate of complications, and ankle range of movement.

RESULTS

The Ilizarov frame was removed after an average period of 12 weeks (range: 11-15 weeks). Only two patients developed pin-tract infections, and none developed osteomyelitis, deep infections, neurovascular injury, malunion, and ankle arthrodesis. Based on the radiological assessment of the reduction of the subtalar joint and fracture fragments, all patients had excellent restored joint structure, with eight and two patients having good-to-excellent and fair ankle scores, respectively. The ranges of plantarflexion and dorsiflexion were 25°-43° and 8°-22°, respectively.

CONCLUSION

The Ilizarov frame could be safe and effective for calcaneal fractures caused by high-energy trauma. This treatment protocol provides an effective approach to treat severe calcaneal fractures caused by high-energy events; however, long-term outcomes are still unknown.
