# Limb Reconstruction Using the Ilizarov Technique Following Giant Cell Tumour Excision in the Proximal Tibia of a 19-Year-Old Female: A Case Report

## TL;DR

A 19-year-old female with a giant cell tumor in her tibia was successfully treated using the Ilizarov technique after tumor removal and complications.

## Contribution

This case report highlights the successful use of the Ilizarov method for limb reconstruction after tumor excision in a young patient.

## Key findings

- The Ilizarov technique provided effective limb reconstruction following tumor resection and osteomyelitis.
- The method proved cost-effective and reliable despite its long recovery time and potential complications.
- Arthrodesis with intramedullary nailing and bone grafting was used prior to Ilizarov reconstruction.

## Abstract

Giant cell tumours (GCTs) of the proximal tibia are a relatively uncommon lesion among all benign tumours. They can occur at various sites including distal femur, proximal tibia and distal end radius. Various management modalities of GCTs occurring in the knee joint have been described for reconstruction as well as arthrodesis. We present a case of a 19-year-old adolescent patient with GCT of the proximal tibia with cortical breach with the collapse of the medial articular surface of the tibia. The patient reported experiencing knee pain and swelling for a long duration. Radiological investigations were suggestive of GCT of the proximal tibia with the medial cortical breach and collapse of the medial tibial articular surface. The patient was managed with a resection followed by arthrodesis using intramedullary nails with bone grafting, followed by Ilizarov reconstruction due to osteomyelitis of the surgical site.

When dealing with relatively aggressive tumours that have breached the cortex, wide resection of the tumour is required. Following this, the reconstruction procedure must ensure good biomechanical tenacity, biological healing, infection resistance, and intact function of the knee joint extension. One option for achieving this is total knee replacement with a customized prosthesis, though this can be costly. Another option is joint arthrodesis with intramedullary nailing or the Ilizarov fixator, which is strongly supported by the existing literature. This case was managed successfully with the above-described method, and complete healing was observed. In conclusion, periarticular long bone tumours, especially around the knee joint, can be managed effectively with the Ilizarov method. Though it has a few disadvantages, such as a long duration of external fixator, non-compliance, and pin tract infections, it still stands as a viable alternative for limb reconstruction due to its cost-effectiveness and time-tested efficacy.
