Abstract:
Objective To evaluate our noval rod-screw construct in anterior single-segmental decompression and fixation for the treatment of Denis type B burst fractures.Methods From February 2007 through May 2010,we treated 28 patients with Denis type B burst fracture.They were aged from 18 to 52 years (average,37.4 years).The fractures were located at T1 1 in 3 cases,at T12 in 10,L1 in 12,and L2 in 3.Of them,7 were complicated with unilateral pedicle fracture and 3 with bilateral pedicle fractures.According to the American Spinal Injury Association (ASIA) scale,the neurological deficits were rated as grade B in 11 cases,as grade C in 9,and grade B in 8.All the patients received anterior single-segmental decompression,titanium mesh and autogenous bone graft,and fixation with our noval rod-screw construct.The therapeutic efficacy was evaluated in terms of visual analogue scale (VAS),cobb angle,and spinal canal encroachment.Results The mean follow-up time was 26 months (range,from 17 to 33 months).The average length of surgery was 144 minutes(range,from 90 to 176 min);the mean blood loss was 580 mL (range,from 300 to 1 100 mL).The mean VAS score,cobb angle and spinal canal encroachment were improved from 8.2 ± 1.5,17.4° ± 4.3° and 53％ ± 16％ preoperatively to 2.7 ± 2.4,9.4° ± 5.8° and 4％ ±2％ at the final follow-up,respectively(P ＜ 0.05).None of the patients exhibited neurological deterioration.Conclusion Our noval rod-screw construct is a safe and effective device that can be used in the anterior single-segmental decompression and fixation for the treatment of Denis type B burst fractures.
