[Anterior operative approach for the treatment of old inferior-cervical fracture-dislocation]

To explore the choice of operative approach for old inferior-cervical fracture-dislocation and analyze the clinical effects of anterior operative approach.

From January 2003 to May 2010, 17 patients with inferior-cervical fracture-dislocation delayed for more than 4 weeks were treated with continued closed skull traction and anterior decompression, bone graft and internal fixation with steel plate. Among the patients, 11 patients were male and 6 patients were female with an average age of 41 years (ranged from 24 to 56 years). The time between injury and operation was from 4 weeks to 3 months. According to Frankel grade, grade A was in 7 cases, B in 4, C in 2, D in 2, E in 2. Neurological function, bone fusion height of vertebral body and cervical sequence and curvature were observed.

The incision of 17 cases obtained primary healing. There was 1 case with hoarseness, and symptoms disappeared after 1 month. The mean time of follow-up was 23 months (ranged from 4 to 47 months). The X-ray films showed satisfactory reduction and good alignment and lordosis. The Frankel grade improved obviously at final follow-up, grade A was in 5 cases, B in 5, C in 1 , D in 3, E in 3.

Single anterior operative approach can successfully reduce old inferior-cervical fracture-dislocation of DF stage I , II and some stage III; anterior decompression, bone graft and internal fixation with steel plate is a safe, effective method for old inferior-cervical fracture-dislocation.
