Abstract:
Objective To investigate the effectiveness of implantation of homologous cancellous and autologous red marrow under endoscope in the treatment of traumatic bone nonunion or bone defect.MethodsTotally 25 patients with traumatic bone nonunion or bone defect were enrolled in this study.The lesion involved the tibia bone in 9 cases,the femur in 13,and the humerus in 3.The grafts were sized 1 to 6 cm in length(mean,2.7 cm).Before the implantation of the cancellous bones,the scar fibrous tissues within the nonunion were removed completely by endoscopy,and then autologous red marrow obtained from the iliac crest was injected.ResultsAll the patients were followed up for 12 to 36 months(mean,25 months).The surgical wounds healed primarily in all of the cases without injuries to the blood vessels and nerves.Bony union was achieved within 4 to 9 months(mean,5.1 months) in 23 of the patients,the other 2 failed because of breaking and loosing of internal fixators.No patient developed re-nonunion and infection.ConclusionsImplantation of homologous cancellous and autologous red marrow under endoscope is effective for traumatic bone nonunion or bone defect with a low rate of complication and high rate of bony union.Since no need to harvest the ilium bone,the method is minimally invasive for the patients.
