Lower Extremity Reconstruction — Orthoplastic Strategy, Flap Selection, and Limb Salvage

This episode reviews the core principles of lower extremity reconstruction, focusing on trauma evaluation, orthoplastic decision-making, flap selection, and limb salvage strategy.Topics include the initial trauma assessment using ATLS, the principle of life before limb, vascular evaluation, hard signs of arterial injury, and decision-making around salvage versus amputation. The episode reviews key concepts such as posterior tibial nerve disruption, prolonged warm ischemia, reperfusion injury, the MESS score, and lessons from the LEAP study, emphasizing that successful reconstruction must consider the whole patient, not just the injured limb.Open tibia fracture management is reviewed through the Gustilo classification, with emphasis on Type IIIB injuries requiring flap coverage and Type IIIC injuries involving arterial repair. Timing is discussed through the Godina 72-hour window, the role of early debridement, fixation, negative pressure wound therapy, biofilm, and the modern orthoplastic approach to coordinated bone stability and soft tissue reconstruction.Reconstructive options are organized by anatomic zone, including gastrocnemius flap coverage for the knee and proximal tibia, soleus and hemisoleus flaps for middle-third defects, and free tissue transfer for distal-third tibial and ankle reconstruction. Additional topics include ALT flap, latissimus dorsi flap, gracilis flap, radial forearm flap, reverse sural artery flap, propeller flaps, medial plantar artery flap for heel reconstruction, and the importance of glabrous plantar skin for weight-bearing defects.The episode also covers lower extremity tumor reconstruction, including sarcoma biopsy principles, the danger of transverse incisions, the “whoops” procedure, MRI before excision, radiation injury, and the need for vascularized non-radiated tissue in hostile wound beds.
