Onychocryptosis is a pathologic condition of the nail apparatus in which the toenail damages the nail fold. It is a common condition provoking pain, inflammation, and functional limitation. It principally occurs in the hallux. Onychocryptosis is one of the most frequent complaints regarding the foot and accounts for many clinical consultations. The disorder has been classified in terms of the stages of the pathologic condition. In our practice, we discovered a clinical entity that was not previously classified in the literature. We classify onychocryptosis into stages I, IIa, IIb, III, and the new stage IV. A treatment plan is offered for each stage of this classification, with both general and specific indications given. In onychocryptosis treatment, it is important to select the surgical technique best suited to the patient’s particular clinical situation. (J Am Podiatr Med Assoc 97(5): 389–393, 2007)
Background
The foot of a newborn is a structure that is under formation and is susceptible to presenting pathologic disorders from the moment of birth. Evidence of the prevalence of clinodactyly in newborns is scarce. Therefore, the objective of this study was to determine that prevalence and its interrelationship with gestational and neonatal factors.
Methods
In a sample of 305 newborns (147 boys and 158 girls), the commonest podiatric medical alterations with either a genetic or a postural component present at the moment of birth were explored physically. The prevalence found in the sample was then related to different anthropometric, gestational, and racial/ethnic parameters of the newborn.
Results
The sex of the newborn was unrelated to any podiatric medical pathology found. Clinodactyly was present in approximately 90% of the fifth toes studied. Breech or transverse fetal presentation and the width of the forefoot affected the appearance of clinodactyly of the fourth and fifth toes. The anthropometric differences between the feet of boys and girls were verified.
Conclusions
The presence of clinodactyly of the fourth and fifth toes in newborns is a frequent clinical finding and should, therefore, be considered in the podopediatric examination. In the neonatal population studied, the pathologic disorders explored did not depend on sex. The prevalence of fourth and fifth toe clinodactyly was significantly influenced by breech or transverse presentation and by forefoot width, but not by the mother's race/ethnicity.
