Abstract:

 Objectives: This study aimed to quantitatively evaluate the clinical impact of posterior calcaneal spur PoCS morphology, specifically spur length and inclination angle, in patients with insertional Achilles tendinopathy IAT. Methods: This retrospective study analyzed 200 patients with symptomatic IAT who underwent standardized weight-bearing lateral ankle radiographs. Spur length and inclination angle were measured, and patients were stratified into nine subgroups based on three length categories 5 mm, 5-10 mm, 10 mm and three angle categories 10, 10-20, 20. Clinical outcomes were assessed using the Visual Analog Scale VAS, American Orthopaedic Foot and Ankle Society AOFAS score, and Victorian Institute of Sport Assessment-Achilles VISA-A score. Kruskal-Wallis tests and multivariate linear regression analyses were used to evaluate associations between spur morphology and outcomes. Results: Both longer spurs 10 mm and steeper inclination angles 20 were significantly associated with worse clinical scores including higher VAS scores and lower AOFAS and VISA-A scores P0.001. Patients with spur lengths 10 mm and angles 20 had a mean VAS score of 7.220.65, VISA-A score of 49.722.54, and AOFAS score of 60.004.24, indicating greater pain and functional limitation. In contrast, patients with spur lengths 5 mm and angles 10 had lower VAS scores 5.180.82 and higher VISA-A 63.433.92 and AOFAS 72.574.33 scores, reflecting lower pain intensity and higher functional capacity P  0.001 for all. Regression analysis confirmed that spur length and angle were independent predictors of clinical outcome P0.001, while age, sex, and BMI were not statistically significant contributors P0.05. Conclusions: Spur morphology - specifically length and angle - has a measurable impact on symptom severity in IAT. Radiographic evaluation of PoCS morphology should be integrated into clinical decision-making for more tailored management.
