Preliminary report of wrapped impacted bone graft using titanium mesh for repair of large segmental bone defect
Objective To investigate the preliminary outcomes of wrapped impacted bone graft using titanium mesh for repair of large segmental bone defect. Methods From January 2009 to December 2012,6 cases of large segmental bone defect of lone bone after fractures were treated with wrapped impacted bone graft using titanium mesh to repair the defect. The location of fracture and defect:1 respective casein femur and humerus，2 respective cases in tibia and radius.The length of bone defect was from 5.2 cm to 9.0 cm with an average of 6.5cm.Fixation methods: intramedullary nail was used in 2 cases and plate in 4 cases.collateral injuries such as tendon or nerve injury could be foundin 2 cases. Cancellous bone with a volume two times than the defect bone was harvested from theposterior or/and anterior segments of the bilateral ilium etc. Titanium mesh was used and placed to wrap the defect, then the bone granules was impacted closely into the titanium mesh.The recovered length of bone defect was from 5.2 cm to 9.0 cm with an average of 6.3 cm. Results Incisions underwent primary healing. Following-up ranging from 12 to 46 months, with an average of 18 months,revealed that all fractures with bone defects healed; the clinical healing time ranged from 4.0 months to 6.5 months with an average of 5.1 months. no breakingor loosening of the fixator was noted.at the last follow-up,the function of the adjacent joints was excellent in 1 case, good in 4 cases and fair in 1 case. Conclusion Wrapped impacted bone graft using titanium mesh for repair of large segmental bone defect has advantages of bing simple, safe, fast in healing and excellent in efficacy.
