My most recent post, from Dec 5th, was on a rare type of cleft hand, the ulnar cleft hand. Ulnar cleft hand is very different and even less common that the classic cleft hand which involves the central hand (classically with middle finger absence). There have been a few manuscripts on the topic of ulnar cleft hand including (among others):
These papers demonstrate how truly rare ulnar cleft hand is. The patients have a cleft between the ring and little fingers and may have deformity of the little finger or, more commonly, have a very small little finger which may be duplicated (i.e., extra little finger).
This case, just like my previous post, is an example of ulnar cleft hand but is more similar to other cases in the literature. Thankfully, the patient has done wonderfully, Importantly, the family wished to remove the abnormal finger with unusual bones and to maintain both little fingers- their goal (as was mine) was to improved alignment for function and appearance.

In these pictures from 2012, the thumb is normal as are the index and middle fingers. However, there are three small digits on the ulnar side of the hand. The central one was removed and the outer two were preserved at surgery and realigned through a bony cut.
