Deep Transverse Metatarsal Ligament Transection in Morton's Neuroma Excision: A Cadaveric Study Examining Effects on Metatarsal Alignment.

Background: In the dorsal incisional approach for Morton's neuroma, it is required to transect the deep transverse metatarsal ligament (DTML) that lies in the interspace between the third and fourth metatarsal heads. The purpose of this study was to evaluate the relationship between transection of the DTML in the third intermetatarsal space and the metatarsal alignment.

Methods: Nine human cadaveric lower extremity limbs were used for this study.
