Objectives
The Ilizarov Frame is considered as one of the most successful measures for the management of bone defects. This study was proposed to detect regenerate site complications if any. Furthermore, can infection take place at the regenerate (corticotomy) site?
Design
This is a retrospective study (with level III evidence) performed at an academically supervised University Trauma Center. The number of subjects included in this study was 90 patients with tibial defects (3–10 cm), of different etiologies. Bifocal segment transport was used in 62 cases, and trifocal technique was applied in 28 cases. Paley’s classification was used to differentiate encountered problems during lengthening. Solid union was defined as union of three of four cortices on AP and lateral radiographs, in both corticotomy and docking sites. A minimum postoperative follow-up period of 2 years was an inclusion criterion in this study.
Results
Corticotomy or regenerate site complications took place in 28 cases. Infection of the regenerate site took place in this study in four cases, and according to our knowledge, this was never recorded in the literature. This was treated using the Ilizarov technique till solid union took place.
Conclusions
Infection of the regenerate site could be anticipated and do take place in cases with severe infection and chronic osteomyelitis that led to bone resorption and bone defects. This could be simultaneously and adequately managed using the Ilizarov frame.
Level of evidence: level III (retrospective study).
