Surgically amputated site of the left tibia and fibula of the Liang Tebo individual: (a) left and right legs with pelvic girdle, demonstrating the complete absence of the distal third of the left lower leg; (b) left tibia and fibula showing the amputation surface, atrophy and necrosis; the bone surface is more porous because lysis occurred to remove the dead bone (necrosis); (c) radiograph of the left tibia and fibula; (d) left tibia medial aspect; (e) left tibia medial aspect; (f) left fibula anterior aspect.
