Analysis of complications using the Ilizarov technique in the correction of limb deformities / 中华骨科杂志

ABSTRACT

Objective To analyze the causes of the complications in the treatment of limb deformities with the Ilizarov technique and to discuss the management and prevention of these complications.Methods From January 2000 to October 2010,846 patients with limb deformities (16 upper limbs and 830 lower limbs) who had been treated with Ilizarov technique were retrospectively analyzed,including 508 males and 338 females with an average age of 25.7 years (range,1.2-72).Statistical analysis was used to compare the type,severity,treatment methods and results of complications.Results Postoperative follow-up lasted for 6 to 30 months,with an average of 18 months.There were 81 cases of pin tract infections,36 cases of restricted joint movements,6 cases of skin thermal damage,7 cases of nerves and vessels injury,8 cases of bone delayed union,2 cases of osteofascial compartment syndrome,7 cases of dislocation,5 cases of fixed needle breakage,8 cases of secondary joint deformities,5 cases of serious osteoporosis,6 cases of skin eruption,4 cases of femoral fractures near to proximal external fixator,3 cases of subsequent fracture after external fixator dismantled,11 cases of deformity recurrence and 1 case of the others.Combining with anti-infection,functional training,physiotherapy,and the second operation therapy and so on,a permanent disability was finally left in 13 patients.Conclusion If the Ilizarov technique was used improperly,there would be multiple complications during the preoperative preparation,surgical procedures and postoperative management.Effective preventive measures should be taken,such as following the principle of the Ilizarov technique,standardizing operation procedures,strictly postoperative observation,correcting postoperative rehabilitation exercise guidance,regular follow-up radiography and postoperative adaptability dynamic adjustment of the external technique.
