Functional Outcomes Following Partial Osteotomy of the Calcaneal Tuberosity for Haglund's Syndrome

Background Haglund's syndrome, a common cause of pain in the posterior heel that consists of painful swelling of the local soft tissues and prominence of the posterosuperior calcaneal projection, presents significant challenges in treatment, particularly when conservative management fails. This study evaluates the functional outcomes following oblique partial excision of the posterosuperior portion (calcaneal tuberosity osteotomy) of the calcaneus for Haglund's syndrome. Methods A cohort of 30 patients, aged 18 years and older, with persistent heel pain unresponsive to conservative treatments, underwent partial osteotomy using a medial or lateral approach. Patients were assessed pre-operatively and post-operatively at six weeks, three months, and six months using the American Orthopedic Foot and Ankle Society (AOFAS) scoring system. Data were analyzed using descriptive statistics and the Friedman test to evaluate changes in AOFAS scores over time. Results The mean AOFAS score improved significantly from 55.17 pre-operatively to 79.27 at six months post-operatively. At six months, 16 (53.3%) participants had AOFAS scores between 80-89, indicating good functional outcomes, while 14 (46.7%) had scores between 70-79. The improvement in functional outcomes was statistically significant (p < 0.001). The study also found both lateral and medial surgical approaches yielded similar results. Conclusion Partial osteotomy of the calcaneal tuberosity is a safe and effective surgical intervention for Haglund's syndrome, leading to significant functional improvements. The use of AOFAS scoring provides a reliable assessment of outcomes, confirming the procedure's efficacy.
