Abstract: Twenty patients of traumatic cervical disc herniation in mono-segment were reconstructed after discectomy with a cage filled with autogenous cancellous illict-bone graft.Neither fracture nor dislocation was found by radiograph or magnetic resonance imaging.The average follow-up period was 22 months (range:6 - 36 months) and the average duration of bone graft fusion 4.9 months.No complications of internal fixation occurred.With this new cage,traumatic cervical disc herniation might be safely treated.
