Abstract:
Objective To explore the significance of designing with monitoring-flap in massive com- pound bone grafts for repairing massive bone defects in extremities.Methods From January 2001 to De- cember 2004,large bone defects in 19 patients(11 men and 8 women,age:6 to 35 years,mean age:18.6 years)were repaired by vascularized free fibular transplant with a monitoring-flap combining with massive deep frozen bone allografts.Average length of the bone defects was 16.6 cm(range,12 to 25 cm).A 7 days' con- tinuously clinical examination including observing the color,turgor,temperature,capillary refill,and bleeding after a needle sticking of the monitoring-falps were used postoperatively,if any one of these were abnormal,the circulation of the compound bone grafts must be in danger and some measures such as re-operation should be taken immediately.Dynamic image analysis was used for evaluating the bone union.Results One monito- ring-flap was vascular artieulo,and the articulo was relieved after exploration and resection of vein thrombus; another one was marginal part necrosis;the remains were normal.All of monitoring-flaps healed normally after 23.2 months(range,6 to 54 months)follow-up.15 patients had the radiographic evidence of bone unions 3 months after surgery.11 patients had been removed intermal fixation,complete bone unios were found one year postoperatively.Conclusion Designing with monitoring-flap in massive compound bone grafts for repairing massive bone defects,and can clearly understand the circulatory statue of compound bone grafts and early pre- dict the final results of massive bone allografts.
