The Haglund’s deformity, which may be difficult to treat non-surgically, is caused by a prominent bone hump in the posterosuperior region of the calcaneus and may be associated with bursitis and foot pain. Many surgical treatments for resistant Haglund deformities have been described. Here, we evaluate the AOFAS scores, pain and other characteristics of patients undergoing removal of the dorsally based wedge from the posterior calcaneus with the Keck and Kelly procedure. The study included 20 patients who had undergone the Keck and Kelly procedure at our center, from 2011 to 2019, and had attended follow-up for at least three years. Analyses were performed retrospectively. Preoperative (immediately before surgery) and postoperative (at last assessment) American Orthopedic Foot and Ankle Society (AOFAS) and visual analog pain scale scores (VAS) were determined, and calcaneal inclination angles were radiologically measured. Additionally, calcaneal pitch angle (CPA), Fowler and Philip angle (FPA), and Bohler angle were recorded. Fourteen patients were female, and six were male, mean age was 45.8 ± 8.1 years. AOFAS scores were significantly increased, whereas VAS scores were significantly decreased after surgery. Postoperative AOFAS scores were correlated with preoperative VAS, CPA, and FPA values. Preoperative VAS scores were correlated with CPA, FPA, and Bohler angle values. FPA and CPA values were correlated positively. It was found that ankle functions improved, and pain levels decreased after Keck and Kelly Wedge Osteotomy was applied for the treatment of Haglund’s deformity. CPA and FPA were associated with both pain levels and ankle function. The Keck and Kelly Wedge Osteotomy procedure appears to be a preferable approach for the surgical treatment of Haglund’s deformity.
