Lower Limb Reconstruction After High-Energy Trauma: Flaps, NPWT and Flap Salvage
Thank you for your feedback!
High-energy lower-limb trauma rarely leaves a simple wound. Bone exposure, vascular injury, contamination and extensive soft-tissue loss force the surgical team to think beyond wound closure and plan reconstruction as part of the entire limb-salvage strategy.
This lecture follows the reconstructive ladder from gastrocnemius and soleus muscle flaps to perforator propeller flaps, ALT and latissimus dorsi free tissue transfer. Clinical cases show how defect location, vascular status, the zone of injury and donor-site options influence the choice between a local solution and microsurgery. Negative-pressure wound therapy is also discussed not simply as a bridge to reconstruction, but as a tool that can sometimes prepare exposed bone or tendon for skin grafting when microsurgical resources are limited.
The second part moves into one of the most time-sensitive areas of microsurgery: postoperative flap monitoring and salvage. The speaker explains what nurses and surgeons should assess clinically, how Doppler monitoring complements examination, what venous congestion looks like, and why a change in capillary refill can completely alter the next step. The discussion also covers thrombosis, re-exploration, thrombolysis, medicinal leeches, CT angiography, postoperative care and the practical realities of deciding how aggressively to pursue limb salvage.
The Q&A adds details that rarely fit into a textbook algorithm: when NPWT may be inappropriate in a contaminated wound, practical points of perforator dissection, how diabetes and atherosclerosis change reconstructive planning, and why a flap that looks acceptable now may become an emergency only hours later.

Principles and Goals in Severe Limb Trauma ReconstructionHow do you decide when a severely injured limb should be salvaged—and when primary amputation is the better reconstruction? Dr Hari Venkatramani explores practical decision-making in mangled upper and lower extremities through complex clinical cases, microsurgical reconstruction, debridement, flap coverage and staged functional recovery.

Regenerative Peripheral Nerve Interfaces (RPNI) for Neuroma and Phantom Limb PainWhy do neuromas keep returning after amputation, and can we give regenerating axons a better target? Dr. Paul Cederna explains the rationale behind RPNI, its technical principles, clinical results, and its growing role in both treatment and prevention of post-amputation pain.
