Background : Freiberg disease is avascular necrosis of head of second metatarsal, but can occur in any metatarsal. Physical
stress causes multiple tiny fracture where the middle of metatarsal meets the growth plate. These fractures impair
blood flow resulting in death of bone cells (osteonecrosis). It is an uncommon condition occupied most often in young
women, athletes and those with abnormally long metatarsals. 80% diagnosed patients are women.
Materials & methods : A 20 year old girl with avascular necrosis of second metatarsal head treated by osteotomy
and K wire fixation of metatarsal and immobilization in toe extension slab. Histopathological analysis reported as
Avascular Necrosis and was confirmed. Routine radiographs and clinical assessment of pain, stiffness, movement of joint
and functional status were done at regular intervals.
Results : A cross sectional study was conducted at a Tertiary Hospital in Chennai (Govt. Stanley Medical College and
Hospital). 402 diabetic patients were included in the study during the period between October 2020 to February 2021.
After obtaining informed consent from the patients, details were collected by face-to face interview using questionnaire
designed for the study.
Results : Patient was immobilized for 3 months and after K wire removal patient developed stiffness of toes and in follow
up treated with analgesics and toe mobilization exercises.
Conclusion : Osteotomy with K wire fixation is an option for management of painful AVN of second metatarsal head
