Introduction
Primary triple arthrodesis is a powerful and reliable procedure for stabilizing and correcting painful rigid flatfoot deformities with a low rate of complications.

The first reports of triple arthrodesis date back to the turn of the 20th century1,2, and the modern technique has seen few modifications since the procedure was popularized by Ryerson in 19233. Surgical techniques have been refined over the past decades, with a corresponding improvement in arthrodesis rates and patient satisfaction. The ability to achieve a stable and corrected hindfoot alignment is closely associated with patient outcomes4, and therefore careful patient selection and preoperative evaluation are critical to achieve a successful result. The most common indications for the procedure include hindfoot deformity and degenerative disease associated with chronic posterior tibial tendon dysfunction or posttraumatic or paralytic equinovarus deformity, although the procedure can be used to address more uncommon situations.

Results
In one of the largest published series of patients managed with triple arthrodesis (111 patients), Pell et al. reported a union rate of 98% at a minimum follow-up of 2 years, with 91% of patients indicating that they would be willing to repeat the procedure under similar circumstances4.
