A new category between external fixation and definitive reconstruction for critical long-bone defects
Temporary Internal Stabilisation for Critical Long-Bone Defects
A modular intramedullary system designed for staged reconstruction, PMMA spacer support, and infection-conscious temporary fixation.
Where CITadel Fits
Designed for temporary internal stabilisation in staged limb reconstruction.
The missing structure in staged reconstruction
In clinical practice, there is a critical phase between initial debridement and definitive reconstruction that remains poorly defined and inconsistently managed.
This applies to
This phase currently lacks a clearly defined internal stabilisation strategy.
Where current solutions fall short
External fixation
- Decreasing stability over time
- Patient discomfort
- Pin-site complications
Internal fixation
- Limited use in infected environments
The transition phase between treatment stages remains structurally undefined.
CITadel system
CITadel is a modular intramedullary stabilisation system combined with a PMMA spacer and selective antibacterial coating.
It is designed to provide controlled internal stability during the transition phase of staged limb reconstruction.
How CITadel is used in staged reconstruction
Debridement
Debridement and defect creation
CITadel Fixation
Internal fixation with CITadel system
PMMA Spacer
PMMA spacer placement
Reconstruction
Definitive bone reconstruction
Designed for staged treatment, not single-stage defect replacement.
Managing uncertainty
CITadel does not attempt to replace reconstruction. It creates a controlled interval in which reconstruction becomes more predictable.
Rather than being just an implant, it functions as a system that structures the most unstable phase of treatment.

Market Relevance
The clinical need addressed by CITadel is not limited to conflict-related injuries.
Why CITadel is different
Current solutions
- External fixation dependency
- Lack of spacer-compatible systems
- Limited internal options for defects
CITadel
- Internal temporary stabilisation
- Designed for spacer-based workflows
- Defect-focused construct logic

About the inventor
Maksym Baida, PhD
Orthopaedic Trauma Surgeon · Developer of CITadel
Over 15 years of clinical practice in traumatology and reconstructive orthopaedics. Associate Professor at Bogomolets National Medical University, Kyiv. CITadel was born from a direct clinical need — the absence of a reliable internal stabilisation option for patients requiring staged reconstruction.
