Question:
An MRI has confirmed a virtually complete tear with fibrillation of the peroneus longus tendon as it passes posterior to the tubercle. One specialist has suggested sewing both ends into the brevis tendon, this provides a 50% chance of increasing the strength of the affected area. Joining the two ends of the longus has been discarded as a solution as the tendon would likely part again. Where else can the ends of this tendon be attached to achieve strength and stability?
Doctor's Reply:
This is not a common injury. The peroneus longus tendon is an important "stap" muscle to the foot. One consideration your surgeon may want to consider is to longitudinally split the peroneus brevis tendon and use it to reinforce the repair of the peroneus longus tendon at the rupture site.
