surgery or trauma. 1 , 2 , 16 , 17 We present an unusual case of a spinal DAVF that was fed by the dural branch of an L-4 radicular artery and was associated with L-4 isthmic spondylolisthesis. To our knowledge, a case of spinal DAVF with isthmic spondylolisthesis at the same level has not been previously reported. We discuss the potential association of isthmic spondylolisthesis with the onset of a spinal DAVF and surgical strategy for 2 potentially related but different pathologies.

R adicular pain of the lower extremity is one of the important symptoms of isthmic spondylolisthesis. The causes of this symptom are compression and/or irritation of nerve roots at the foraminal level around the isthmic site. The compressive factors are proliferative fibrocartilagenous tissue at the isthmic site, a bulged or herniated intervertebral disc at the slipped segment, foraminal stenosis associated with large slip, and a combination of these factors. Due to the mechanically unstable nature of isthmic spondylolisthesis, a fusion procedure is

I sthmic spondylolisthesis (IS) is one of the most common types of spondylolisthesis of the lumbar spine, and it manifests with a defect of the pars interarticularis or isthmus causing an anterior slip of the vertebral body. 6 Isthmic spondylolisthesis usually occurs on L5–S1 (90%), but occasionally on higher levels like L4–5 or L3–4 as well. 20 Presenting signs and symptoms may include those caused by neurological compression or by spinal deformity. The majority of patients with spondylolysis and spondylolisthesis respond to conservative, nonoperative

T he term spondylolisthesis is derived from the combined Greek terms spondylos (vertebra), and listhesis (to slip). The term literally means the “slippage of one vertebra forward in relation to the adjacent vertebra.” Five types were classified according to the Wiltse classification system: dysplastic, isthmic, degenerative, traumatic, and pathologic. 18 Isthmic spondylolisthesis is caused by a defect in the pars interarticularis area of the lamina, and is the most common spondylolytic disorder. The reported incidence is 4%–6% of the general population

clinical findings, as well as the grade of spondylolisthesis, were recorded. The inclusion criteria were as follows. 1) The presence of isthmic spondylolisthesis of Grade 1 or 2 at any level, and low-back pain with or without sciatica and neurogenic claudication that was referable to the lumbar spine (that is, claudication or radicular symptoms were brought on by either walking or prolonged standing, were relieved by sitting or flexing, and occurred without a vascular or neuropathic pathological basis). 2) Lack of improvement after at least 6 months of conservative

Isthmic spondylolisthesis, which is demonstrated in 4 to 8% of the general population, is one of the most common types of spondylolisthesis. The three subtypes of this condition all manifest some variation of a pars interarticularis defect as a result of recurrent injury to that structure. A multifactorial origin is postulated for this disease; mechanical, hereditary, and hormonal factors are believed to play a role. Presenting signs and symptoms may include those referable to neurological compromise or those related to the spinal deformity. The majority of patients with spondylolysis and spondylolisthesis respond to conservative, nonoperative treatment. Pain, neurological compromise, and cosmetic defects unresponsive to traditional therapies may require surgical intervention. Surgical options include any combination of the following: neural decompression, bone fusion, instrument-assisted fusion, and reduction. In this paper, the natural history and treatment options are presented, and the supporting literature is reviewed.

A lterations in lumbar paraspinal muscle (PSM) morphometry have been documented in low-back pain (LBP) 6 , 7 , 18 , 20 and degenerative listhesis, 35 with atrophy of the multifidus (MF) muscle frequently reported in these conditions. Paraspinal muscle morphometry has not been analyzed in isthmic spondylolisthesis (IS), a condition with strong physiotherapy connotations, especially in the lower grades. We hypothesized that patients with IS have atrophic PSMs and that the PSM areas in these patients have a bearing on the radiological degenerative changes

S pondylolisthesis is a manifestation of multifactorial spinal instability characterized by the subluxation of one VB over another. Isthmic spondylolisthesis is 1 of 5 subtypes, named for the lytic defects of the pars interarticularis (spondylolysis), which are the initial mechanisms of instability. Perched on the sloping face of the sacral promontory, the lower lumbar spine endures significant axial loading forces. Arching out over the pelvic ring, the forces of muscular contraction are transferred through the posterior elements. The spine is dependent on

obtained in 35 consecutive patients surgically treated for isthmic spondylolisthesis; the procedure involved segmental fixation and either posterolateral fusion or PLIF. Our goal in comparing the techniques was to investigate whether there are differences in clinical and functional outcome, as well as biomechanical property differences. Clinical Material and Methods Demographic Data and Selection Criteria Between June 1997 and June 2000, 35 adult patients with isthmic spondylolisthesis underwent implantation of an identical pedicle screw system.
