A new radiologic measurement for the diagnosis of Haglund's deformity

Area of Science:

• Orthopedic Surgery
• Radiology
• Biomechanics

Background:

• Haglund's deformity, characterized by bony enlargement on the posterior calcaneus, is associated with posterior heel pain and calcaneal tendinopathies.
• Existing radiologic methods for assessing Haglund's deformity have limitations in accurately quantifying the deformity's size, location, and associated calcaneal changes.
• A precise and reliable radiologic measurement is crucial for diagnosis and surgical planning.

Purpose of the Study:

• To introduce and validate a novel angular radiologic measurement for Haglund's deformity.
• To assess the diagnostic accuracy of this new method in symptomatic and asymptomatic feet.
• To compare the efficacy of the new method against previously described radiologic formulations.

Main Methods:

• A retrospective radiologic study was conducted on 31 feet surgically treated for Haglund's deformity and posterior heel pain.
• A control group of 60 asymptomatic feet was included for comparison.
• A new angular measurement technique was applied to lateral weight-bearing radiographs.

Main Results:

• The novel angular measurement correctly identified Haglund's deformity in 85% of symptomatic feet.
• The method demonstrated a low false-positive rate of 14% in the asymptomatic control group.
• This technique effectively measures the size and location of the posterosuperior calcaneal deformity and the angle of calcaneal verticalization.

Conclusions:

• The described angular radiologic measurement is a highly accurate and reliable method for diagnosing Haglund's deformity.
• This approach provides comprehensive assessment, including calcaneal angle, surpassing the diagnostic capabilities of prior methods.
• The method shows significant potential for improving the diagnosis and management of conditions related to Haglund's deformity.
