INTERMITTENT FLEXOR HALLUCIS LONGUS DISLOCATION: ULTRASOUND FINDINGS

We report a case of intermittent dislocation of the flexor hallucis longus at its passage in the retro-malleolar area, related to a post-traumatic detachment of the retro talar pulley from the medial tubercle of the talus. High-resolution ultrasound depicted the anterior dislocation of the tendon during dynamic stress, by asking the patient to flex his hallux against the examiner resistance, with the ankle in slight dorsiflexion. The tendon is normally relocated after the dynamic maneuver. Tendon dislocation was associated with a painful snap.

1 / 5

What was the overall conclusion about using QMUS for muscle assessment in this patient population?

 

QMUS was only useful for initial assessment but not for monitoring recovery

QMUS caused significant patient discomfort

QMUS was feasible and provided reliable muscle measurements

QMUS was found to be ineffective for this application

2 / 5

How was the feasibility of QMUS determined in the study?

 

By measuring the impact on patient symptoms

By evaluating cost-effectiveness

By assessing patient tolerance and consistency of the measurements

By comparing QMUS results with other imaging techniques
