Haglund's syndrome, known in the literature as "High Heel" and "Winter Heel", was first described by orthopedic surgeon Patrick Haglund in 1928. It refers to pain in the hindfoot of mechanical origin, associated with foot-shoe impingement linked to a morphological anomaly of the posterior-superior tuberosity of the calcaneus, with inflammatory pre- and retro-achillary bursitis and achilles tendinopathy. Diagnosis is essentially clinical and radiological. Its management is divided between medical treatment and surgical treatment, which remains the fundamental pillar of treatment. The aim of this study is to investigate the clinical and radiological features of Haglund syndrome and d evaluate the functional and radiological results of its treatment.
