Review of Calcaneal Osteotomies Fixed With a Calcaneal Slide Plate.

Background: The calcaneal slide osteotomy is a common procedure used for the surgical correction of heel varus and valgus deformities. A variety of fixation methods exist including screws and plates. The literature shows a high rate of hardware prominence with screws leading to subsequent removal of hardware. Few studies have examined the use of plates for fixation of a calcaneal osteotomy. The purpose of this study was to assess outcomes following fixation of a calcaneal osteotomy with a calcaneal slide plate.

Methods: This is a retrospective consecutive case series of all patients who underwent either a medial or lateral calcaneal slide osteotomy using the specialized calcaneal slide plate between September 2013 and December 2018 by a single surgeon. The primary outcome measures were the rate of hardware removal, healing of the calcaneal osteotomy, and any associated complications such as infection or incision healing delays. Patient baseline demographics and procedure-related data were recorded. The minimum follow-up was 4 months. A total of 81 procedures were performed using this calcaneal slide plate.

Results: All of the patients had one or more additional procedures at the same time as the calcaneal osteotomy. All of the calcaneal osteotomies healed without displacement. Only 1 patient (1.2%) returned to the operating room and had removal of the calcaneal slide plate, which was after osteotomy union for an infected wound. There were no cases of hardware failure or removal due to it being symptomatic.

Conclusion: A specialized calcaneal slide plate was an effective fixation device for both medial and lateral calcaneal slide osteotomies for a variety of foot and ankle conditions. The union rate was 100% and none of the patients had hardware symptoms, which is an improvement on published reports of symptomatic hardware after calcaneal slide osteotomy.

Level Of Evidence: Level IV, retrospective case series.
