Toe, Partial Absence of
Definition:
Toe, Partial Absence of
Objective: The absence of a phalangeal segment of a toe or hallux
Comments: The part that is absent may be specified. The distal modifier specifies the loss of the distal phalanx; clinically this is defined by the absence of the nail. The proximal modifier specifies the loss of the proximal or middle phalanx with the nail still present. It may be difficult to know which phalanx is absent without X-rays and even then, the missing bone may not be identified (note no attempt is made to distinguish missing middle from proximal phalanges). In this situation the location adjective should be removed. Note that this finding is distinct from Short toes, (which are reduced in length but have the normal number of phalangeal segments). Partial absence of the hallux is an alternative term that may be used for the first toe.
