Forty-five patients with low back pain (LBP) of longer than six months' duration and for whom all conservative therapies failed were placed in a pantaloon cast for a two- to four-week trial period. Significant pain relief occurred in 31 (69%) of these patients. Of these 31, 23 patients were treated with spinal arthrodesis using lateral, intertransverse process fusions with iliac bone grafts. Before fusion, the painful lumbar segments were determined by facet analgesic blocks or the normal saline acceptance test. After an average follow-up period of 14 months, 17 (74%) had significant pain relief. The pantaloon cast may be an effective tool for identifying those chronic LBP patients who might benefit from spinal stabilization procedure.
45例腰痛持续时间超过6个月且所有保守治疗均无效的患者被置于马裤型石膏中进行2至4周的试验期。这些患者中有31例（69%）疼痛明显缓解。在这31例患者中，23例接受了使用外侧横突间融合并植骨的脊柱融合术。在融合前，通过关节突镇痛阻滞或生理盐水耐受试验确定疼痛的腰椎节段。平均随访14个月后，17例（74%）疼痛明显缓解。马裤型石膏可能是一种有效的工具，用于识别那些可能从脊柱稳定手术中获益的慢性腰痛患者。
