This paper presents a long-term follow-up of 23 patients with collapsed lumbosacral disks showing evidence of fifth lumbar root compression treated by facetectomy without fusion. Fifth lumbar root compression is usually caused by protrusion of the fourth lumbar disk. If this is not present the fifth lumbar root will almost invariably be found to be impinged upon laterally in the foramen by one of several mechanisms, which are detailed in this paper. Decompression of the roots at the fifth lumbar foramen may be done by either unilateral or bilateral facetectomy depending upon whether the symptoms are unilateral or bilateral. There has been no forward displacement with unilateral facetectomy and only slight forward movement of the fifth lumbar vertebrae on the sacrum with bilateral facetectomy. There has been good relief of symptoms in most patients. Arthrodesis, as a rule, is not necessary.
本文介绍了对23例腰椎间盘塌陷且有第五腰神经根受压证据的患者进行的长期随访，这些患者接受了不融合的小关节切除术治疗。第五腰神经根受压通常由第四腰椎间盘突出引起。如果不存在这种情况，几乎总是会发现第五腰神经根在椎间孔内被几种机制之一向外侧压迫，本文对此进行了详细阐述。根据症状是单侧还是双侧，可通过单侧或双侧小关节切除术对第五腰椎椎间孔处的神经根进行减压。单侧小关节切除术后没有向前移位，双侧小关节切除术后第五腰椎在骶骨上仅有轻微向前移动。大多数患者的症状得到了很好的缓解。通常，融合术并非必要。
