Raphaël Vialle, Antoine Feydy, Ludovic Rillardon, Carla Tohme-Noun, Philippe Anract, Magali Colombat, Gonzague De Pinieux, Jean-Luc Drapé, and Pierre Guigui

cage was packed with iliac crest autograft. Postoperative Course A thoracolumbosacral orthosis was provided to assist in fusion during the first 4 months. No postoperative complication was observed. The patient was regularly evaluated by the orthopedic surgeon during a 6-year follow-up period. No local recurrence was observed. Case 2 Presentation and Examination This 23-year-old woman had a 6-month history of low-back pain. Lumbar spine radiography revealed an osteolytic tumor at L-3 associated with a 30° lumbar scoliosis ( Fig. 4A and B

Hemangiopericytoma-like synovial sarcoma of the lumbar spine

Case report

Nikolaos Sakellaridis, Helen Mahera, and Spiros Pomonis

W e describe the case of a soft-tissue tumor of the lumbar spine, which was initially diagnosed as hemangiopericytoma. After the initial operation, the patient underwent additional surgery for tumor recurrence. A histological analysis revealed that the lesion was a synovial sarcoma. Case Report History and First Operation. This 36-year-old woman first presented and was admitted to our department in January 1997. Three years earlier she had undergone surgery at another hospital for a tumor of the lumbar spine. The histological diagnosis at

radiated down the posterior aspect of his right thigh. He experienced numbness over the lateral aspect of his right calf and foot. The onset of pain was gradual and without apparent causative trauma. His symptoms had responded slightly to 3 months of outpatient conservative therapy, including nonsteroidal antiinflammatory medication, pelvic traction, and sacral blocks. After undergoing radiographic and MR imaging studies of the lumbar spine, the patient was referred to our institute for persistent pain and an intraspinal mass lesion. Examination On admission

Unilateral progressive alterations in the lumbar spine: a biomechanical study

Gabriel C. Tender, Scott Kutz, Richard Baratta, and Rand M. Voorhies

study we evaluate the biomechanical behavior of the lumbar spine after unilateral progressive resections. Fig. 1. Photographs of spine models showing the left L-5 pars interarticularis (black stripe). Left: Posterior view. Right: Oblique view, showing the underlying L-5 nerve root in the intervertebral foramen. Materials and Methods Six human cadaveric L5—sacrum FSUs were used. The age of the cadavers ranged from 50 to 80 years (median 58 years), and the sexes were equally represented (three specimens from males and three from females). Each

Lumbar spine injuries in athletes

Ian F. Dunn, Mark R. Proctor, and Arthur L. Day

✓Lumbar spine injuries in athletes are not uncommon and usually take the form of a mild muscle strain or sprain. More severe injuries sustained by athletes include disc herniations, spondylolistheses, and various types of fracture. The recognition and management of these injuries in athletes involve the additional consideration that to return to play, the lumbar spine must be able to withstand forces similar to those that were injurious. The authors consider common lumbar spine injuries in athletes and discuss management principles for neurosurgeons that are relevant to this population.

Vertical cleft through the superior articular process of the lumbar spine: fracture or anomaly?

Case report

Takaaki Miki, Masanori Oka, Hiromichi Hama, Mitsuhiro Shima, Eikazu Hirofuji, and Seizuke Tanaka

A vertical fissure through the superior articular process of the lumbar spine is unusual and, as only one previous case has been reported, 1 we describe herein our recent experience with such a case. Case Report This 47-year-old Japanese man came to our clinic in Kinki University Hospital complaining of low-back pain of 3 days' duration. He had been engaged in a job of carrying objects weighing 25 kg for 8 hours a day for the last 3 weeks. Otherwise he could not recall any precipitating cause of the pain. Physical examination revealed no abnormal

Dynamic examination of the lumbar spine by using vertical, open magnetic resonance imaging

Hans-Ekkehart Vitzthum, Alexander König, and Volker Seifert

S tabilization following decompressive surgery of the lumbar spine is indicated only in selected cases of patients with degenerative disorders of the lumbar spine. Therefore, preoperatively, it is important to identify clearly those patients with signs of segmental instability of the lumbar spine. Open MR imaging technology allows investigators to examine the spinal column in patients during flexion—extension and rotation. Of special importance is the assessment of the relationship among soft-tissue structures, nerves, and skeletal structures, because

Association between low-back pain and lumbar spine bone density: a population-based cross-sectional study

observed in unaffected individuals. 12 , 21 There is ongoing debate as to whether bone mineral density (BMD) is associated with LBP. Authors that have studied small samples argued that lower BMD at the lumbar spine was observed among LBP patients, and thus, that LBP increased the incidence of osteopenia. 13 However, others have found that study participants with LBP have significantly higher lumbar BMD than participants without LBP and concluded that the presence of rotational asymmetry or motion restriction was associated with elevated BMD at the affected vertebrae

Percutaneous pedicle screw fixation of the lumbar spine: preliminary clinical results

Kevin T. Foley and Sanjay K. Gupta

have been associated with extensive blood loss, lengthy periods of hospitalization, and significant cost. 12 The purpose of this paper is to describe a technique and instrumentation designed by the senior author (K.T.F.) for minimally invasive posterior fixation of the lumbar spine in which percutaneous screws and rods (Sextant; Medtronic Sofamor Danek, Memphis, TN) are used. Our initial clinical experience will also be included. Although the insertion of percutaneous lumbar pedicle screws has been previously reported, 6–8 a minimally invasive technique involving

Surgical management of metastatic disease of the lumbar spine: experience with 139 patients

vertebrectomy 14 or single-stage posterior vertebrectomy, with reconstruction and placement of instrumentation. 1 In contrast, only 20% of spinal metastases involve the lumbar spine. The lumbar spine has several unique biomechanical and anatomical features that can potentially complicate successful regional decompression and stabilization in the setting of metastatic disease. Chief among these are the large size and high weight—bearing demand of the lumbar VBs, the transition between the kyphotic rib-fixated thoracic spine to a more mobile lordotic lumbar spine, and the
