矩形Luque棒内固定治疗腰椎滑脱症

LUQUE ROD RECTANGLE FIXATION FOR SPONDYLOLISTHESIS

本院1987年使用矩形Lugue棒内固定横突间植骨融合术治疗腰椎滑脱症14例,取得良好疗效。年龄在40岁以上13例。L_(4-5)滑脱13例.Ⅰ°滑脱5例,Ⅱ°滑脱9例。随访10例,随访时间6个月～2.5年。疗效优8例,良2例,未发生假关节。单纯植骨融合于腰椎和腰骶关节假关节发生率较高,约在25％～33％。使用矩形棒椎板下铜丝固定,横突间植骨融合,能获得坚强内固定,有利于植骨愈合,增强脊柱稳定性。附合Luque(1978)提出脊柱节段器械(SSI)内固定原则,同时能矫正畸形,使椎管或(和)神经根减压,不但对腰椎滑脱症有良好疗效,还能应用其他脊柱病变和损伤引起的下腰背疼痛。

From 1987, a rectangle made of Luque rods was used in fixation and intratransverse fusion for treating 14 cases spondylolisthesis with satisfactory results. The patients were aged 39-59 and had their defomites at L5 in 10 cases, L4 in 3 and L3 in 1, and of Ⅰ° in 5 cases and Ⅱ° in 9 cases. Ten of the treated patients were followed up for 6 m to 2.5 yr, displaying excellent results in 8 cases and good results in 2 cases, This procedure avoided the formation of pseudoarthrosis, which would result from simple arthrod-esis in about 25-33% of the cases. The rod rectangle fixation technique can provide firm internal fixation, facilitate the union of bone graft, reinforce the stability of the spine and decompress the vertebral canal and nerve roots. Therefore it is useful not only for treating spondylolisthesis but also for relieving the lower back pains resulted from other spinal lesions and injuries.
