Objective To study the effect of fascial flap with vessels inducing the vascularization of uncel-lular tissue engingeering complex and the regenration of bone on the repair of bone defect, so as to provide the basis for the clinical application. Methods An animal model of bone defect on adult Newzland rabbits'right radial bone was established .and autologous red bone marrow were taken out and mixed into uncellulax tissue engineering comple-xes with OAM which contained BMP. The experiment animals were divided into two groups : experiment group and control group( n = 12 for each ). The control group was only implanted with complexes, meanwhile, the experiment group had fascial flap with vessels. By microsurgery technology,a non-named fascial flap with vessels was prepared, which belonged to capillary net,around the bone defect,and let it wrap tissue engineering complex,fill up bone de-fect. In a certian time, radiograph(X-ray) and light density measure was conducted, gross morphology and histological inspection was exmained. Bone shape measurement analysis and image of vessel analysis were conducted. All the sta-tistics were analyzed by the SPSS 11.5 software. Results Because of mechanically preventing fiber connective tis-sues and surrounding soft tissues from entering the areas of bone defect by fascial flap, it can keep bone defect having a relative stable environment ;The subfascial space itself, and also the shape and mass of filled-in subject had the de-cisive effect on the results of the regeneration of the bone; Owing to the establishment of blood supply during the con-structing tissue engineering complex. The experiment group was obviously superior to the control group. Compared with control group,the absor bance obviously increased in experiment group [(0. 732 ± 0. 021 ) vs (0. 651± 0.018)] (P < 0. 001 ) four weeks after the operation; also the bone trabecular body was significantly increased [(2.32±2.57)% vs(19.37±3.52)% ,(8.37±3.52)% vs(30.24±3.42)% ,(28.57±2.98)% vs(58.76± 4.62)% ,(47.24±3.42)% vs(88.72±5.84)%] ,and capillary area [(5.04±1.62)% vs(17.53±2.86)%, (10.37 ±2.96)% vs(35.24±1. 13)%,(18.20±2. 12)% vs(48.76±4. 62)%,(17.82 ±2. 74)% vs (57.72 ±5.84)%] (P <0.05) at each time period(4 weeks,8 weeks,12 weeks,and 16 weeks after operation). Despite of growth of implant's internal vessel, the number and speed of forming bone trabecula and cartilaginous tis-sue, even developing of mature bone structure, recreating of diaphysis structure, reconstructing of marrow cavity, ab-sorbing and decomposing of implant, the experiment group was obviously superior to the control group. Conclusions The induction of fascial flap with vessels shows double effects, one of which is the vascularization of uncellular tis-sue engineering complex and the other is membrane guided bone regeneration, So the method has a wonderful effect on the repair of bone defect.
