Nail growth measurement employing nail indentation--an experimental follow-up study of nail growth in situ.

摘要: Nail growth was studied over 20 weeks in five healthy volunteers by indenting eight nails each subject with a dental burr. The indentations were drilled the middle part of lunula proximal edge indentation 1 mm from cuticle. Their volume measured filling them an elastic two-component material immediately after and 4, 8, 12, 16 thereafter. as reflected changes could be followed for 8-12 thumb, finger second toe big toe. most rapid outgrowth, weeks, occurred finger. decrease approximately 30-35%, they travelled towards distal end nail plate, also reflects bed. This study has shown that measurement their provides reliable simple method growth.
