Case Report


We report a case of bilateral ulna stress fractures following bilateral femoral fractures associated with long-term bisphosphonate use. The patient is an 84-year-old woman receiving 15 years of bisphosphonate therapy. She did not have any preexisting medical conditions which are known secondary causes of bone loss. She was mostly housebound and used a walking frame for ambulation. She presented with atraumatic right ulna pain and subsequent atraumatic left ulna pain a month later. She was treated conservatively in backslabs and her bisphosphonate was stopped. Investigations did not reveal any secondary causes of osteoporosis or metabolic bone disorders.
