Minimally Invasive and Endoscopic Treatment of Haglund Syndrome.

Haglund syndrome is a triad of posterosuperior calcaneal prominence (Haglund deformity), retrocalcaneal bursitis, and insertional Achilles tendinopathy. The sources of pain include the posterior calcaneal wall cartilage, retrocalcaneal and subcutaneous adventitial bursa, and the Achilles tendon. Resection of the posterosuperior calcaneal tubercle, bursectomy, excision of the Achilles tendon pathology, reattachment of the Achilles tendon, gastrocnemius aponeurotic recession, and flexor hallucis longus transfer have been proposed as surgical treatment options. All of them can be performed endoscopically or under minimally invasive approaches.
