Introduction: Nonoperative management of calcific insertional Achilles tendinopathy (CIAT) may fail in 10-30% of patients, and various operative procedures have been described to manage those. Methods: A modified Zadek (dorsal closing wedge) calcaneal osteotomy, without removing the calcific deposits and without detaching the insertion of the Achilles tendon, was performed between November 2016 and December 2017 in 25 consecutive patients (mean age 53.5 years), who were followed for at least 2 years. Results: The osteotomies had united at an average of 5 weeks. Two superficial wound infections (8%) were documented.

VAS and VISA-A scores had significantly improved at 3 months postoperatively (p < .001) and continued to improve for 24 months. Conclusion: The modified Zadek osteotomy, without excision of the intra-tendinous calcification, was safe, and significantly improved clinical outcome in patients with CIAT at 2 years after surgery.

Abstract

Introduction: Nonoperative management of calcific insertional Achilles tendinopathy (CIAT) may fail in 10-30% of patients, and various operative procedures have been described to manage those. Methods: A modified Zadek (dorsal closing wedge) calcaneal osteotomy, without removing the calcific deposits and without detaching the insertion of the Achilles tendon, was performed between November 2016 and December 2017 in 25 consecutive patients (mean age 53.5 years), who were followed for at least 2 years. Results: The osteotomies had united at an average of 5 weeks. Two superficial wound infections (8%) were documented. Patients had returned to their normal activities at an average time of 23 +/- 7.7 weeks. Three out of four patients, who practised recreational sport activity, returned to their pre-injury level. VAS and VISA-A scores had significantly improved at 3 months postoperatively (p < .001) and continued to improve for 24 months. Conclusion: The modified Zadek osteotomy, without excision of the intra-tendinous calcification, was safe, and significantly improved clinical outcome in patients with CIAT at 2 years after surgery.
