Abstract

Abstract : Background: A small size and difficulties with shaping a medial femoral condyle corticocancellous bone flap are factors limiting its use. The goal of this study was to evaluate range of vascular supply to a medial femoral condyle corticocancellous bone flap to determine whether harvesting of larger flaps and performing a flap osteotomy would compromise the vasculature of a flap's bone. Methods: Twenty-four limbs were dissected and medial femoral condyle corticocancellous bone flaps were harvested with skin paddles. Thirteen of 24 flaps had subperiosteal osteotomies simulating shaping a bone for reconstruction. A pedicle artery was perfused with red latex. Medial femoral condyle corticocancellous bone flap vascularization was evaluated by cutting the bone into 1-cm blocks and assessing the number of Haversian canals filled with red latex. Results: Length of harvested flaps was 7 to 13 cm, thickness was 0.5 to 3 cm, and width was 1 to 3 cm. Pedicle length was between 3.5 and 9 cm (mean ± SD, 6.6 ± 1.6 cm). Red latex filled bone vessels at a distance of 6 to 11.5 cm from the distal end of a flap (8.2 ± 1.4 cm). Skin paddles were filled with latex in all cases. Conclusion: A medial femoral condyle corticocancellous bone flap had sufficient blood supply, allowing for harvesting flaps up to 11 cm long, and subperiosteal osteotomy did not compromise the vasculature of the flap's bone.
