Background: Haglund syndrome is a common disease that causes posterior heel pain. This study compared the clinical outcomes of dorsal closing wedge calcaneal osteotomy (DCWCO) and posterosuperior prominence resection (PPR) for the treatment of Haglund syndrome.Methods: This retrospective study included 12 patients who underwent DCWCO and 32 patients who underwent PPR from January 2010 to August 2016. Patients were evaluated using the American Orthopedic Foot Ankle Society ankle-hindfoot scale (AOFAS), Victorian Institute of Sport Assessment Scale for Achilles tendinopathy (VISA-A), Fowler-Philip angle, Bohler's angle, and calcaneal pitch angle preoperatively and postoperatively (at 3 months, 6 months, 1 year, and the latest follow-up).Results: Both groups exhibited a significant increase in their AOFAS and VISA-A scores after surgery.The DCWCO group had lower AOFAS scores than the PPR group at 6 months (77.6 ± 5.1 vs. 82.8 ± 7.8; P =0.037) but had higher scores at the latest follow-up (98.2 ± 2.3 vs. 93.4 ± 6.1; P =0.030). The DCWCO group had lower VISA-A scores at 3 months (56.9 ± 13.9 vs. 65.2 ± 11.0; P =0.044) but higher scores at the latest follow-up (98.2 ± 2.6 vs. 94.3 ± 5.0; P =0.010) than the PPR group. Both groups exhibited significant changes in the Fowler-Philip angle and Bohler's angle after surgery. The postoperative Fowler-Philip angle of the DCWCO group was greater than that of the PPR group (35.9°± 4.9° vs. 31.4° ± 6.2°; P =0.026). However, there was no statistically significant difference in any other angle of the two groups postoperatively.Conclusions: Compare to PPR group, the DCWCO group had poorer short-term clinical outcomes but provide better long-term function and symptom remission. This method can be a good option for those patients with higher functional expectations.
BackgroundHaglund deformity, first described by Patrick Haglund in 1928, is a prominence in the posterolateral heel that causes posterior heel pain [1]. It is generally associated with insertional Achilles tendinopathy (IAT) and retrocalcaneal bursitis, which comprise the Haglund triad or Haglund syndrome [2,3]. Surgical intervention is a suitable option when conservative treatment for more than 6 months has failed [4]. Common surgical methods, including posterosuperior prominence resection 4 (PPR), retrocalcaneal decompression, and endoscopic treatment, generally have good short-term clinical outcomes [5,6]. However, a few patients still experience some degree of pain after surgery, especially after PPR [7]; therefore, another surgical method is required for better outcomes.Dorsal closing wedge calcaneal osteotomy (DCWCO) was first described by Zadek for the treatment of IAT [8]. Keck and Kelly proved that DCWCO was an effective treatment for Haglund deformity in 18 patients [9]. Further, Miller reported that wedge osteotomy of the calcaneus body combined with resection of the superior calcaneus showed good results in 16 patients (18 feet) [10]. Dimitrios treated IAT with dorsal wedge calcaneal osteotomy in 52 athletes, al...
