A new classification for Freiberg’s disease

•Freiberg’s osteochondrosis is an uncommon presentation with a variety of surgical management strategies employed after failure of conservative treatment.•Established classification systems are not used to guide surgical management and no classification system us currently is used by surgeons to guide surgical treatment.•The use of thin slice CT to evaluate the ‘zone’ of the defect may allow surgeons to pre-operatively determine the use of a rotational osteotomy using a simple classification system.•Use of a classification system that guides treatment preoperatively aims to assist both surgical planning and patient consenting and counselling.
