Abstract

Chronic extensor hallucis longus tendon ruptures are very rare, and may lead to hallux dysfunction. To the best of our knowledge, reconstruction of a chronic extensor hallucis longus rupture using interposed scar tissue has not been previously reported. Our results show that direct repair method using interposed scar tissue for chronic extensor hallucis longus rupture can successfully restore function of the hallux and provide good satisfaction in carefully selected patients.

Intraoperative photo shows gap between the tendon stumps filled with thick connectivce tissue (A), direct repair incorporating scar tissue interposed between the tendon stumps (B).

Figure 4.

Histologic examinations of a specimen revealed interposed scar tissue composed of thick collagen fibers running parallel to the tendon axis, with highly cellular fibrovascular tissue (H&E stain, ×200).
