Nine patients were treated with ten intertransverse process lumbar spine anthrodeses using fresh-frozen crushed corticocancellous allogeneic bone as graft material. No instrumentation was used. The clinical and roentgenographic follow-up period ranged from one to three years. Seven procedures showed successful arthrodesis and three demonstrated pseudarthroses. Increased age and systemic disease were associated with an increased risk of pseudarthrosis. Persistent back pain was associated with pseudarthrosis. Compared with 58 patients treated with intertransverse process lumbar fusion with autogeneic iliac bone as graft material, the overall fusion rate is inferior: 70% versus 92%, respectively.
9例患者接受了10次腰椎横突间融合术，使用新鲜冷冻的粉碎皮质松质异体骨作为移植材料。未使用内固定器械。临床和影像学随访时间为1至3年。7例手术显示融合成功，3例显示假关节形成。年龄增长和全身性疾病与假关节形成风险增加相关。持续性背痛与假关节形成有关。与58例使用自体髂骨作为移植材料进行腰椎横突间融合术的患者相比，总体融合率较低：分别为70%和92%。
