Pseudoepiphysis Index Finger Metacarpal Base

" Phylogenetically, there are potential epiphyses at both the proximal and distal ends of the tubular hand bones.... A persistent expression of the distal epiphysis of the thumb metacarpal is called a pseudoepiphysis. The pseudoepiphysis appears earlier than its standard counterparts, then fuses rapidly. BY the sixth or seventh year it has been incorporated and is inconspicuous. Pseudoepiphysis have also been noted at the proximal ends of the finger metacarpals, usually of the index finger. Its only clinical significance is that it must be differentiated from an acute fracture." -- Rockwood and Green, Fractures in Children. 4th Ed.1996, p326.
