CR – PA view of the thumb demonstrates a short and broad 1st metacarpal with closed epiphysis and enlarged greater multangular bone.


Etiology of short 1st metacarpals depends upon its width and the association of other abnormalities. A short and thin 1st metacarpal may be familial. A short thin 1st metacarpal with other hand/wrist deformities may be associated with radial ray hypoplasia syndromes or Fanconi anemia. A short thin 1st metacarpal may also be associated with Taybi-Linder syndrome, 18 q- syndrome, and Juberg-Hayward syndrome. A short normal width or broad 1st metacarpal may be idiopathic or related to arthritis, infection, trauma, neoplasm (ostechondroma), or sickle cell disease.
