“…Vascularized MFC corticoperiosteal and corticocancellous flaps have been used to treat nonunions in both small and long bones, respectively [1,[3][4][5]10]. We report a case of chronic thrombosis of the DGA as a potential complication of this flap.…”

“…While the flap was initially proposed for small bone nonunions [5], its favorable characteristics and osteogenic potential have led to its application in long bone nonunions [4]. The advantages of this flap include minimal donor side morbidity, a long noncritical vascular pedicle, and relatively reliable anatomy [7].…”

“…O retalho corticoperiosteal do côndilo medial do joelho é baseado no feixe vascular genicular medial, ramo da artéria femoral. Neste estudo, o diâmetro médio da artéria foi de 2,5mm, encontrando-se dentro dos limites de 1,5 e 3,8, relatados por outros autores (4,6,7) . O comprimento do pedículo também assegura a viabilidade do procedimento, pois a média do seu comprimento (7,0cm) proporciona alternativas de mobilidade e disposição espacial na área receptora.…”

Vascularized Bone Grafts from the Dorsal Wrist for the Treatment of Kienböck Disease

et al. 2016

Previous literatures described various methods of treatment for Kienböck disease depending on the patient characteristics, the severity of the symptom, and radiological staging. 1-8 Treatment options range from conservative measurements to surgical interventions. 9-12 Several authors advocated a biomechanical approach to reduce load transmission on the necrotic lunate, [13][14][15][16][17][18][19] and good clinical results have been reported in joint leveling procedures such as radial shortening or ulnar lengthening 20-22 and in radial or ulnar wedge osteotomy. 23,24 Hori et al 25 introduced a biological approach of revascularization for necrotic bones based on their experimental results. Since then, there have been several donor sites available for vascularized bone graft in the treatment of AbstractPurpose The objective of this article is to evaluate functional and radiological outcomes of vascularized bone grafts for stage 2 and 3 Kienböck disease. The outcomes of three different donor sites via dorsal approach of the wrist were compared. Pearls and pitfalls in surgical technique were discussed. Methods There were 28 patients who underwent vascularized bone grafts, including the extensor fourth and fifth compartmental artery graft of distal radius in 8 patients, the first and second supraretinacular intercompartmental artery graft of distal radius in 12 patients, and the second dorsal metacarpal neck graft in 8 patients. Average age was 32 years, and radiological grading according to Lichtman classification was stage 2 in 8 patients, stage 3A in 10 patients, and stage 3B in 10 patients. Temporary pinning fixing the midcarpal joint was conducted for 10 weeks postoperatively. Results Follow-up periods averaged 70 months. Pain reduced in 27 patients, and visual analog scale for pain of pre-and postoperative level averaged 59 and 18. Range of wrist flexion and extension motion improved from 87 to 117 degrees, and average grip strength improved from 21 kg preoperatively to 33 kg postoperatively. Carpal height ratio had almost no change from 0.52 to 0.53. Fragmentation of necrotic bone healed in 7 of the 14 cases. Comparative analyses of functional and radiological outcomes between three donor sites found no significant difference. Conclusion Three different vascularized bone grafts from the dorsal wrist and hand area demonstrated favorable and comparable functional outcomes. It was technically important to elevate vascular bundle with surrounding retinaculum or fascia, to include sufficient periosteum, and to insert the vascularized bone as the cortex aligned longitudinally.
