Congenital Malalignment Of The Great Toenail (CMGT) is a exactly as the name describes. It has been hypothesized that this condition is caused by traction upon the nail plate by the dorsal expansion of the lateral ligament at the distal interphalangeal joint.
The great toe may be congenitally malaligned. There may be thickening, discoloration, and shortening of the nail plate. At times, overgrowth of the lateral nail fold may lead to severely ingrown toenails.
If mild, trimming may be all that is needed. In young patients, spontaneous improvement often occurs. For thick nails, a urea-containing product can be used. If severe, surgical realignment can be done. Specifically, surgical excision of the dorsal expansion of the lateral ligament permits immediate correction of the anomaly without nail plasty.
