The treatment of Tibialnon-union with Compressive External Fixtor.

Objective:Through observing the effect of half-ring fixator on the treatment of tibial non-union,to evaluate the compressive external fixation on the repairment of bone defect.Mothed:49 cases (37 cases male,12 cases female)of tibial non-union (the non-union occurred from 7 to 132 months)were treated by half-ring external fixator.meanwhile,7 cases accompanied by infection and bone defect treated with bone graft,5 cases accompanied by infection treated with internal fixtor remove and local flap transfer,10 cases accompanied by limbshorten treated with limb-lengthening at the same time of compressive fixation treatment.Result:18 cases of closed fracture with fixed failure.18 cases with infection(36.7%),10 case present,shorten limb with bone defect,the length of bone defect was from 2 to 10cm(mean 4.8cm).All cases were treated by half-ring external fixator with compnession.and opening bene graft were used in 7 cases with bone infection and defect,local transfered flap in 5 cases with bone exposure,bone lengthening in 10 case with limb shortening. Result:All cases had got perfect bone healing, healing time were from 2.5 months to 10 months.average 5.4 months.The limb shortening in 10 cases were corrected by bone lengthening,the length was from 4.5～13.5cm.average 7.5cm,the function of joint were improved.Conclusion:Compression external fixation is an effective method for treatment of tibial non-union.
