Matrixectomy: If your doctor believes the destruction of the nail matrix is necessary after removing the toenail, he or she will perform a partial or full matrixectomy (or matricectomy), which is permanent toenail removal by applying a chemical agent (most commonly phenol or sodium hydroxide) to the matrix.
Denailing is the extraction of the nails from the fingers and/or toes, either as a medical procedure to treat severe nail infections, or as a method of torture. The United Nations Istanbul Protocol describes nail removal and the insertion of objects such as wire under the nail as forms of torture. Removed nails are capable of growing back normally over several months if the nail matrix is left intact through surgical extraction.
