All-Inside Endoscopic Zone 1 Flexor Hallucis Longus Transfer: A Cadaveric Feasibility Study., Kevin D Martin, Yi Wei, Adam G F Smith, Franco Piscitani, Luke M Martin, Brian Steginsky, Brian Tscholl, Nathaniel A Bates

Surgery Articles

BACKGROUND: Endoscopic flexor hallucis longus (FHL) tendon transfer addresses chronic Achilles tendon ruptures. Traditional percutaneous plantar incisions gain FHL length but risk neurovascular injury. This study evaluated the feasibility of an all-inside endoscopic FHL zone 1 tenotomy and transfer technique, which avoids plantar incisions by using zone 1 of the FHL tendon. We hypothesized that this technique would (1) provide sufficient tendon length, (2) avoid neurovascular damage, and (3) securely anchor the FHL tendon without tunnel blowout.

METHODS: Ten cadaveric all-inside endoscopic zone 1 FHL tendon transfers were performed without fluoroscopic guidance. Specimens were independently assessed post hoc by 2 …
