Ilizarov technique. Results and difficulties.
Of 100 cases treated by the Ilizarov method, 91 patients were reviewed from February 1985 to March 1990. There were 32 tibial fractures (29 open) and 21 nonunions (nine infected). There were 47 cases of limb lengthening (28 tibia and 19 femur). The results were as follows: good, 83%; fair, 13%; and poor, 4%. Slight and intermittent pain in some wire of the device was frequent (69%). Average bone healing time in tibial fractures was 4.95 months and 5.83 months in tibial nonunions. In bone-lengthening operations, the average lengthening index in the tibia was 1.02 months/cm (lengthenings ranged from 3 cm to 10 cm, with a mean of 5.71 cm), whereas in the femur, the average lengthening index was 1.14 months/cm (lengthenings ranged from 3 cm to 7 cm, with a mean of 5.34 cm). Manually-tensed wires produced frequent problems (24.5%), whereas wire tensed by the dynamometric tensioner produced problems in only 7.8% of the cases. Despite good results, the Ilizarov technique requires adequate training to reduce an overall complication rate (approximately 30%).
