Foot, Long

Definition:

Objective: Foot length more than 2 SD above the mean for a newborn of 27-41 weeks gestation OR foot length above the 97th centile for individuals from birth to 16 years of age

Subjective: A foot that appears longer than expected for age

Comments:

Note that for females over the age of 16 years, the curves are essentially flat by 15 years of age, so the 16-year-old norms and distribution can be used for older individuals [Anderson et al., [1956]; Hall et al., [2007]]. However, the male norms still have significant growth at 16 years, where the graph ends. Therefore, only subjective assessments can be made for males over the age of 16 years. For infants, the norms are specified in SD, per the primary source [Merlob et al., [1984]]. Because of the wide range of normal for foot measurements, it may be hard to discriminate a long foot of normal width from that of a narrow foot of normal length, thus the subjective definition is substantially inferior. If the toes are also long, that should be coded separately.
