Abstract
IntroductionMorton's neuroma is predominantly attributed to chronic nerve entrapment within third space adjacent metatarsals, the deep transverse metatarsal ligament (DTML), and the plantar skin. While conservative treatments are of election, failures require alternative interventions such as ultrasound-guided injections and various surgical procedures, including minimally invasive neurectomy and DTML release. This study aimed to anatomically assess the risks associated with the endoscopic dorsal surgical decompression of Morton's neuroma. Materials and methodsTwenty feet from ten fresh-frozen cadaveric specimens underwent a dorsal percutaneous approach for endoscopic access. Surgical procedures were monitored by three foot and ankle surgeons. Post-surgical anatomical dissections were conducted to evaluate potential risks to surrounding structures. ResultsThe endoscopic technique successfully sectioned the DMTL in all specimens (100%) without iatrogenic injury of tendons, nerves, or arteries, while lumbricals may be at risk. ConclusionEndoscopic dorsal decompression of Morton's neuroma presents as an accessible minimally invasive surgical option with low risk of collateral associated injuries.
