Objective:
To evaluate the effect of treatment of calcaneal malunion fracture with isolated subtalar arthrodesis.
Methods:
Twenty-one patients with calcaneal malunion fracture, with 21 diseases feet, all males, underwent tenolysis of peroneal tendon, lateral exostectomy, and isolated arthrodesis of subtalar joint and were followed up for 16 months (8-47 months). American Orthopedic Foot and Ankle Society and pain score systems were used to evaluate the changes of symptoms. X-ray films were taken to observe the changes of the bones.
Results:
The calcaneal deformity was greatly improved in all the patients and the symptom of pain disappeared or was alleviated. The mean post-operational AOFAS score was 71.3 (44-85) points, higher than that before the operation [36.7 (18-56) points]. The pain mean post-operational score was 2.0 (0-4) points, much lower than that before the operation [8.2 (7-10) points].
Conclusion:
Surgical treatment including tenolysis of peroneal tendon, lateral exostectomy, and isolated arthrodesis of subtalar joint is effective on calcaneal malunion fracture.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
