title: Management of fibular hemimelia using the Ilizarov method at Siriraj Hospital in Thailand.
abstract: BACKGROUND
  Fibular hemimelia is one of the most common congenital longitudinal bone deficiencies. Previous treatment protocols called for amputation of the deficient limb; while others made attempts to save the limb. The objective of treatment is to restore function and achieve patient satisfaction. The authors evaluated the outcomes of the Ilizarov technique for the treatment of leg-length discrepancy and bone associated deformities in patients with fibular hemimelia. The present study also evaluated and assessed complications, knee and ankle function, and patient satisfaction with the treatment.
  
  
  METHODS
  Nine patients with fibular hemimelia who underwent tibial lengthening using the Ilizarov method were reviewed in the present study. Initial condition data, including age, gender type offibular hemimelia, initial limb-length discrepancy, predicted limb-length discrepancy, and the data were collected and analyzed. Activity level, patient satisfaction, complications, and residual leg-length discrepancy were assessed at the end of treatment.
  
  
  RESULTS
  According to Achterman and Kalamchi classification, there were 4 patients with Type IA, 3 patients with Type IB, and 2 patients with Type II. In Type IA, the affected leg-length discrepancy and mean age at the initial treatment were 3.25 cm and 7.75 years, respectively. In type IB, the affected leg-length discrepancy and mean age at the initial treatment were 5.83 cm and 4.3 years, respectively. In Type II, the affected leg-length discrepancy and mean age at the initial treatment were 5.5 cm and 5 years, respectively. The mean follow-up was 5 years (range: 7-10). The mean lengthening was 7.52 cm (range: 4-13). The lengthening index was 1.28 mo/cm. The mean residual leg-length discrepancy was 0.94 cm. There was ankle joint stiffness and mild equinous foot in type II cases, but patients could walk well without gait aid. No patients were experiencing pain by the end of treatment. All patients expressed satisfaction with this technique.
  
  
  CONCLUSIONS
  The Ilizarov technique for bone lengthening of the tibia has shown satisfactory results in the treatment of all types of congenital fibular hemimelia and should be considered an attractive alternative to amputation, as measureable functional improvement can be expected.
