Dorsally Based Closing Wedge Osteotomy of the Calcaneus for Insertional Achilles Tendinopathy

Surgical management may be indicated for patients with insertional Achilles tendinopathy (IAT) after failure of nonoperative management, and various surgical techniques have been described.

We present the technique and results of modified dorsal closing wedge calcaneal osteotomy, performed in a cohort of 28 consecutive patients. We hypothesized that this will be a safe procedure that can improve hindfoot pain and function for most patients who will return to preoperative daily life and sports activities.

Case series; Level of evidence, 4.

A modified dorsal closing wedge osteotomy was performed in 28 patients (mean age, 54.7 years) from November 2015 to December 2016. All patients were followed for at least 2 years postoperatively.

All osteotomies united at a mean of 5 weeks. The mean anatomic change in calcaneal length was 4 mm (range, 3-6 mm). The overall complication rate was 10.7%. There were 2 superficial wound infections (7.1%) and 1 instance of sural nerve-related paresthesia (3.5%) reported. All patients returned to their presurgical level of activities at a mean of 23 ± 8.0 weeks. Further, 3 of 4 patients who participated in recreational sports activities returned to their preinjury level. Visual analog scale and Victorian Institute of Sports of Australia-Achilles scores significantly improved postoperatively (P < .001) and continued to improve for 24 months.

The modified dorsal closing wedge calcaneal osteotomy is a safe procedure and significantly improved pain and function in patients with IAT at 2 years after surgery.
