Idiopathic non-traumatic or stress fracture of clavicle

Stress fracture is a known entity with common occurrence in lower limbs especially in military recruits and ath- letes. Stress fracture of the upper limb is a rare occurrence, but is much rarer in clavicle. Only 16 to 20 such case re- ports have been mentioned in literature. Stress fracture or non-traumatic idiopathic fracture of the clavicle in a non athletic patient without any pre-disposing factors is very rare and till date only 2 such cases have been reported. Such patient requires a detailed work-up and high index of suspicion on the part of treating physician. Our case re- port is the 3rd such case report and highlights several points with regards to its diagnosis, treatment and prognosis.
