| Abstract |
Objective
Several techniques have been used to achieve solid fusion after decompression by anterior cervical discectomy or corpectomy. These have included autograft or allograft bone fusion, with or without plating. Although significant morbidity occurs around the autologous graft site, autologous iliac bone has been the preferred source of graft tissue in these cases. We review here patients who underwent discectomy or corpectomy followed by placement of an allograft with autologous bone chips and a plate.
Methods
Ninety consecutive patients underwent anterior cervical discectomy or corpectomy, using a fibular allograft with autologous bone chips and a plate, and were then followed for up to 5 years by a single surgeon. This group's conditions included herniated discs(50), ossification of the posterior longitudinal ligament(OPLL)(15), spondylosis(15), and trauma(10). The mean follow-up period was 32.2 months, with a range from 24 to 60 months.
Results
Perioperative complications requiring revision included three cases of transient hoarseness and two of graft extrusion due to lower vertebral body fracture. There were no transfusions, infections, neurologic injuries, or deaths. At one year post operation, there was 98.9%(89/90) radiographic fusion with no motion, kyphosis, graft collapse, or symptomatic screw plate back out. These patients were both functionally and clinically stable.
Conclusion
For cervical discectomy or corpectomy, using fibular allograft with autologous bone chips and plating showed higher clinical success and lower morbidity rates than did using autograft. Allograft allows fusion without the use of a halo and eliminates the donor site morbidity that accompanies autograft. |
