Resection of Haglund’s deformity using the arthroscopic method with the three-portal technique

. Haglund?s deformity represents a reactive enlargement of the posterosuperior aspect of the calcaneus and often causes pain that can significantly disturb everyday activities. If the patient?s condition did not improve after six months of non-surgical treatment, the surgical treatment could be taken into consideration. Although Haglund?s deformity is successfully treated by endoscopic calcaneoplasty with two portal techniques we decided to apply a slightly newer technique - arthroscopic surgery with three portal techniques. Case outline. Patient with clinically and radiographically confirmed Haglund?s deformity was operated on using arthroscopic calcaneoplasty with three portal techniques. The postoperative recovery went without complications and full weight-bearing was allowed after 4 weeks. Completely return to sports activities was allowed after 4 months. Conclusion. Arthroscopic calcaneoplasty with three portal techniques turned out to be a safe and cost-effective surgical method in the treatment of Haglund?s deformity. There is still not enough data in the literature regarding this type of surgical treatment, but the good postoperative functional results are extremely encouraging since this surgical technique enables faster recovery and fewer postoperative complications.
