Their surgeons will also be contacted at 12, 26 and 52 weeks to determine if there has been any further surgery or other complications, and to gain their opinion on fracture union. Copies of their routine pre-operative and twelve week X-rays will be collected for review. Preoperative X-rays will be classified according to the AO classification system into the 9 sub classifications of tibial shaft fractures by a panel of three orthopaedic surgeons. Two orthopaedic surgeons experienced in trauma, who will remain blinded to the treatment arm of the patients, will assess the twelve-week X-rays to determine if union has occurred. Fracture union rates at twelve weeks will be quantified. Fracture union will be defined as mature callus bridging in three of four cortices over the fracture site on two radiographic views. If there is disagreement amongst the two surgeons, the X-rays shall be reviewed by a third surgeon whose opinion shall be final. For fractures that have failed to unite at twelve weeks, their surgeons will be contacted to determine union rate at six months and their plain X-rays will be collected and reviewed. If they have undergone any surgery, their medical records and operation reports will be examined to determine the reason for the surgery and the exact operation undergone. This is to ascertain surgical revision rate and union rate at 12, 26 and 52 weeks post injury.
