What is the probability that offspring of two heterogeneous parents will be homologous recessive?
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.
This procedure is called a cheilectomy. Removing the bone spur allows more room for the toe to bend up and alleviates pain caused when pushing off the toe. This procedure also can be combined with other bone cuts that change the position of the big toe and further relieve pressure at the top of the joint.
