Objectives

Narrative objectives1

An anterior ankle impingement syndrome (AAIS) is reported to occur in a high percentage of patients after ankle labrum fracture surgery. However, the effects of anterior ankle soft tissue dynamics and tissue elasticity on AAIS are unknown. In this study, we used ultrasound to clarify the relationship between the rate of change in anterior ankle soft tissue thickness, shear modulus, and AAIS.

Assessment

Primary outcomes

The evaluation periods were 3 months and 6 months after surgery. The measurement positions were 10degree ankle plantar flexion and 0degree plantar dorsiflexion in the resting standing position. The tibialis anterior tendon, extensor hallucis longus tendon, and extensor hallucis longus tendon were visualized on long-axis images of the talar pulley and tibia using an ultrasound machine. Anterior soft tissue thickness was measured as the shortest distance from the convexity of the talar pulley to the tendon directly above it. The rate of change in anterior ankle soft tissue thickness was determined by dividing the value at 0degree ankle plantar dorsiflexion by the value at 10degree plantar flexion. The average shear modulus (kPa) was calculated using shear-wave elastography.

Other related information

The study included 24 patients who had undergone open repair and fixation for ankle fractures (AO classification A and B) between May 2022 and March 2023. Inclusion criterion was the ability to walk without load restriction. Exclusion criteria were dorsiflexion range of motion less than 0degree, history of neurological lesions, Chronic Ankle Instability,hallux valgus with pain during weight bearing,and FPI6 score of 6 or higher or 0 or lower for clubfoot and clubfoot,respectively. Twenty subjects who finally met the criteria were included in the study. The healthy group consisted of 20 age- and sex-matched subjects. The healthy group was defined as those without neurological or orthopedic diseases. The evaluation periods were 3 months and 6 months postoperatively.
