Ankle Impingement Syndromes: Diagnosis and Management Techniques

Ankle impingement syndromes encompass a spectrum of conditions in which aberrant contact between osseous or soft‐tissue structures leads to pain, restricted range of motion and impaired function. Anterior impingement typically produces pain on forced dorsiflexion and is often associated with osteophyte formation at the tibio­talar joint or hypertrophy of synovial tissue. Posterior impingement presents as pain during plantarflexion and is frequently linked to an os trigonum or soft‐tissue entrapment. Diagnosis relies on a combination of clinical examination—identifying reproduction of symptoms during specific manoeuvres—and imaging, including plain radiography, computed tomography, ultrasonography and magnetic resonance imaging to clarify bony morphology and soft‐tissue pathology. Management strategies range from conservative measures, such as targeted physiotherapy, activity modification and image-guided injections, to minimally invasive approaches including ankle arthroscopy and endoscopic resection of offending osteophytes or accessory ossicles. Recent advances in biomechanical assessment and three-dimensional modelling have refined both diagnostic accuracy and surgical planning. The global burden of ankle impingement is substantial among athletes and active individuals, but it also affects those with prior trauma or anatomical variants. Improved understanding of the interplay between tissue mechanics and anatomical risk factors underpins the evolving paradigm of personalised treatment.

Research from Nature Portfolio

Recent studies have employed high‐resolution ultrasonography combined with shear-wave elastography to quantify alterations in anterior ankle soft-tissue stiffness following surgical fixation of fractures. Findings indicate significantly elevated shear modulus values at three months with partial normalisation by six months, suggesting progressive remodelling and potential targets for rehabilitation. Complementary anatomical research has revisited the inferior fascicle of the anterior inferior tibiofibular ligament through meticulous cadaveric dissection and classification. This work revealed that neither the presence nor positional variants of the inferior fascicle reliably predict impingement during dorsiflexion, shifting attention towards dynamic factors and synovial interplay in anterolateral syndromes.

Ankle Impingement Syndromes: Diagnosis and Management Techniques publication trend

The graph below shows the total number of articles in ankle impingement syndromes: diagnosis and management techniques across all publications each year (not limited to Nature Index journals).

Technical terms

Anterior ankle impingement: Pain and restricted dorsiflexion caused by encroachment of bony or soft structures at the front of the ankle joint.

Posterior ankle impingement: Pain and limited plantarflexion resulting from entrapment of the os trigonum or soft-tissue elements at the back of the ankle.

Shear modulus: A quantitative measure of tissue stiffness determined by shear-wave elastography, reflecting resistance to deformation.

Statistical shape modelling: A computational method that captures and quantifies three-dimensional bone shape variations across a population to identify patterns associated with pathology.

Os trigonum: An accessory ossicle located posterior to the talus that can contribute to posterior impingement when it restricts joint motion.
