Scaphoid non union advanced collapse

Discussion:

Patient presented with stage 3 scaphoid non union advanced collapse  (SNAC wrist). Subsequently the patient was surgically treated with a proximal row carpectomy. Three months post operation the patient continued to complain of wrist pain.

There is a know higher failure rate (of pain relief) with proximal row carpectomy when there is severe degenerative changes involving the lunocapitate (stage 3 SNAC) prior to surgery 1. Therefore, radiologist need to be vigilant and make an early diagnosis.
