Common site of fracture in tibia is: (A) Upper one-third, (B) Junction of upper two-thirds and lower one-third, (C) Lower one-third, (D) Middle one-third
Answer is B. The tibia is commonly fractured at the junction of upper two-thirds and lower one-third of the shaft as the shaft is most slender here. Such fractures may unite slowly, or may not unite at all as the blood supply to this pa of the bone is poor. This may also be caused by tearing of the nutrient aery.Ref: Chaurasia; Volume 2; 6th edition; Page no: 25
