Ilizarov bone transport as a treatment of congenital pseudarthrosis of the tibia: a long-term follow-up study.

Vanderstappen J, Lammens J, Berger P, Laumen A - J Child Orthop (2015)

Bottom Line: It describes long-term results and highlights any prognostic factors that could predict the final outcome.The present data confirm a good primary healing rate.United bone is often of inferior biological and mechanical quality, so lifetime protection with intramedullary devices, braces or a combination of both is recommended.

ABSTRACT

Purpose: Most studies on congenital pseudarthrosis of the tibia (CPT) report on the short-term union rate and refracture rate but do not take into account the long-term outcome. This review includes patients treated with an Ilizarov bone transport, who all reached skeletal maturity. It describes long-term results and highlights any prognostic factors that could predict the final outcome.

Methods: The records of patients with CPT treated with an Ilizarov bone transport in our institution were retrospectively evaluated.

Results: A total of 12 consecutive patients were studied. The mean follow-up was 24.5 years (range 6-39 years). Primary consolidation was seen in ten patients (83 %). Half of these patients had a refracture. At final follow-up, eight patients experienced union and four remained un-united, of whom one had an amputation.

Conclusions: The present data confirm a good primary healing rate. However, tibial union at final follow-up was only seen in 67 %, indicating that refracture is the main issue. United bone is often of inferior biological and mechanical quality, so lifetime protection with intramedullary devices, braces or a combination of both is recommended.

Fig1: Primary union rate for the three age groups (age at first surgical procedure)

Mentions: Primary consolidation, described as union after the initial treatment, was seen in ten patients (83 %). However, half of these had a refracture during follow-up. A second Ilizarov treatment again achieved successful union in three cases. In one patient, tibial union could not be achieved and in another patient, a below-the-knee amputation had to be done. The refracture-free interval was three months, two years, four years and 18 years and unknown in one patient, respectively. Figures 1 and 2 describe the primary union rate and refracture rate for the three age groups (age at first surgical procedure).Fig. 1
