Opinions differ regarding the surgical treatment of posterior calcaneal exostosis. After failure of conservative treatment, open surgical bursectomy and resection of the calcaneal prominence is indicated by many investigators. Clinical studies have shown high rates of unsatisfactory results and complications. Endoscopic calcaneoplasty (ECP) is a minimally invasive surgical option that can avoid some of these obstacles. ECP is an effective procedure for the treatment of patients with posterior calcaneal exostosis. The endoscopic exposure is superior to the open technique and has less morbidity, less operating time, fewer complications, and the disorders can be better differentiated.
