OBJECTIVES: To demonstrate the feasibility of spinal canal decompression through the posterior transpedicular approach in @entity1 with thoracolumbar burst @entity174 . METHODS: We present 25 consecutive @entity1 (19 @entity1 and 6 @entity1 ; mean age 36 years; age range, 24-48 years) with incomplete @entity51 (ASIA B and C) resulting from thoracolumbar burst @entity174 treated by posterior transpedicular spinal canal decompression and @entity1347 . Canal compromise at presentation was 51.7 +/- 11.2%. RESULTS: The mean surgical time was 122 minutes (range, 108-122 minutes), and the mean @entity190 was 528 +/- 123 ml. Canal compromise improved to 15.3 +/- 7.8%. At a mean followup of 14 months (range, 6-18 months), fourteen @entity1 improved to ASIA D and were able to walk with an orthosis; seven improved to ASIA C, and four had no improvement (ASIA B). Seven ASIA B and all ASIA C @entity1 had immediate postoperative neurological improvement to ASIA C and ASIA D; two ASIA B @entity1 improved to ASIA C within six weeks after the operation. Anterior decompression was necessary in two (8%) ASIA B @entity1 who did not improve after the initial operation; these @entity1 , subsequently improved to ASIA C. There were no intraoperative complications. @entity2737 occurred in two @entity1 and were treated with wound care and antibiotics; @entity281 occurred in one @entity1 and was treated with debridement and antibiotics. CONCLUSION: Posterior transpedicular spinal canal decompression and instrumentation is a reasonable alternative technique to anterior decompression procedures and circumferential fusion, providing for satisfactory canal decompression and neurological improvement.
