The incidence of neurovascular complication after the fracture of the clavicle is very low. We experienced a case of delayed neurovascular complication about 3 months after the fracture of the clavicle. The patient was a 45-year-old man who fell down and was injured while riding a motorcycle. Initially, he showed no symptoms in his upper extremity, and was treated with a clavicle brace. Later, numbness and muscle weakness appeared in the segmental area from C5 to Th1 of the upper extremity. Osteotomy, autologous bone graft, and internal fixation by plate led to good results, and the symptoms gradually disappeared.
The patients has returned to his profession as a carpenter.
