ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the efficacy and the feasibility of bending rod reduction in situ technique in treating low lumbar burst fracture.</p><p><b>METHODS</b>From March 2007 to June 2009, 21 patients with low lumbar burst fracture were retrospectively analyzed, 11 cases were in L3,6 in L4 and 4 in L5. There were 16 males and 5 females, ranging in age from 25 to 59 year with an average of 37.9 years. According to ASIA classification, nerve function was level A in 2 cases, level B in 2, level C in 10, level D in 4 and level E in 3. Pedicle screws were implanted and bending rod reduction in situ technique was applied through posterior approach. Radiographic and neurological scores were compared before and after operation.</p><p><b>RESULTS</b>All patients were followed up from 12 to 39 months with an average of 16.5 months. Radiographic examinations demonstrated that anterior height of fractured vertebral body was from 57.9% preoperatively to 94.1% postoperatively (P < 0.01 ); sagittal index was from 29.1 preoperatively to 0.240 postoperatively (P < 0.01). Spinal canal occupation ratio was from 49.6% preoperatively to 13.4% postoperatively (P < 0.01). Nerve function was level A in 2 cases,level B in 0, level C in 0, level D in 4 and level E in 15.</p><p><b>CONCLUSION</b>Bending rod in situ technique could achieve 3-column reduction in 3-dimentionally at the same time, and reconstruct the stability of low lumbar.</p>
