    Notes: Summary The authors studied the usefulness of MR imaging in the diagnosis of an osteoid osteoma occuring within the C4 left uncinate process. It was detected by scintigraphy and diagnosed by CT. On T2-weighted MR images the nidus showed a very low signal intensity with an increased signal within the adjacent end-plates. This pattern was misleading and more suggestive of degenerative disk disease.

    Notes: Abstract We report a 17-year-old asymptomatic patient with a partially collapsed seventh cervical vertebra due to a haemangioma revealed by conventional radiographs performed for army enrolment. Given radiological evidence of aggressiveness, percutaneous vertebroplasty by injection of methyl meth-acrylate cement was performed to prevent complications. CT a year later showed no progression of the lesion. The patient remains asymptomatic.

    Notes: Summary Thirty-three patients with recurrent sciatica after lumbar-disk surgery were studied for recurrent herniated nucleus pulposus (HNP) by CT alone and CT-diskography (CTD). Twenty-six patients underwent surgical reexploration allowing correlation with CTD. CTD made a correct diagnosis of recurrent HNP in twenty-one patients showing an extravasation of the contrast medium from the disk space into the medullary canal. In two cases CTD was positive for recurrent HNP but surgery showed only fibrosis. The amount of contrast leak was very small in these two cases along the posterior common longitudinal ligament, and the junction with the disk was very narrow. Because of their clinical presentation three patients with negative studies were operated upon. One showed only fibrosis and the two others showed an associated disk fragment. Among the twenty-one true-positive cases, seven showed a combination of recurrent HNP and scarring. Contamination of CSF by the contrast medium through the dura was observed in two patients. Although a prospective comparative study between CTD and IV-contrast-enhanced CT is necessary, CTD appears to be a useful diagnostic procedure for recurrent HNP after surgery of the lumbar spine.

    Description / Table of Contents: Summary Traumatic spondylolisthesis of the axis is rarely associated with neurological deficit. The authors describe a case of complete tetraplegia due to spinal cord rupture at T1 without any other osteoligamentous lesion at the level. The mechanism of this lesion is discussed; it seems to be due to hyperflexion, with preceding hyperextension responsible for the C2 pedicular fracture.
    Notes: Résumé Le spondylolisthésis traumatique de l'axis est rarement accompagné de déficit neurologique. Les auteurs décrivent un cas de tétraplégie complète due à une rupture de la moelle epinière en T1 sans aucune autre lésion ostéoligamentaire à ce niveau. Le mécanisme de cette lésion est discuté et semble être une hyperflexion précédant l'hyperextension responsable de la fracture des pédicules de C2.

    Notes: Abstract The authors report their experience concerning complications of spinal metastasis surgery. The purpose of this study was to assess the frequency of such complications and analyse the factors influencing their occurrence. The records of 145 patients treated between 1982 and 1991 for metastatic disease of the spine were retrospectively reviewed for intra- and postoperative complications. Other factors such as radiation therapy, emergent nature of surgery, and neurologic deficits were analysed for potential correlations with the frequency of complications. Twenty-seven (18.6%) patients developed postoperative complications. Wound dehiscence and infection (11%) were the most frequent complications. Statistical analysis showed a significant influence of three factors: preoperative radiation therapy, paraplegia before surgery, and surgery under emergency conditions. The rate of complications in this surgery is lower than might be expected and can be significantly reduced. Surgery should be performed before radiation therapy and before appearance of substantial neurologic deficits.

    Notes: Summary The authors present a retrospective study of 535 consecutive anterior approaches to the cervical spine back to 5 years. The data were analyzed for post-operative complications. This surgical procedure has been commonly used for more than 40 years, but the post-operative complications due to the anterior approach itself were presented with few accompanying statistics, with various and contradictory results. Injury to nearly all of the structures has been reported in the literature, the more frequent problems are hoarseness and dysphagia; other complications include perforation of the oesophagus, hematomas, vascular injury⋯ Analysis of this data allows to understand better the specific problems related to this surgical approach, and to suggest precautions at each stage of the course of exposure of cervical vertebrae.

    Description / Table of Contents: Summary Forty thoracolumbar fractures, including thirty-two with neurological complications, were stabilized with the Hartshill-Dove rectangle. Its configuration explains its better rigidity compared to two separated Luque rodes. With this device one can only neutralise the reduction, without compression or distraction. When neurological signs exist, we performed a wide laminectomy or a posterolateral decompression before the osteosynthesis. We can contour the rectangle with whatever profile we desire. Double wires were the only way of fixing the rectangle. The number of stabilized levels depends on: the site of lesion: seven levels fixed in the thoracic spine and four to five in the lumbar spine, the type of fracture: more levels were instrumented for translation or compression-distraction fractures than for compression ones. Posterolateral graft is extended only one level above and one down the fracture. Local and regional kyphosis was corrected by more than fifty per cent. Translation were perfectly corrected 16 out of 19 times. We had only one neurological complication which was due to a postoperative epidural hematoma and not to the manipulation of the wires. The main ways to avoid iatrogenic complications are to operate under medullary monitoring, to perform wide windows on neural arches and to manipulate wires with high precision. The best indication for this very simple device are: on thoracic spine: all fractures with neurological deficit. If there is no neurological trouble: translations, contiguous lesions, vertebral kyphosis over 30° and the association with a sternal fracture; on lumbar spine: translation and compression-distraction fractures. With the compression fractures we prefer to adopt pedicular screwing or anterior arthrodesis.
    Notes: Résumé Quarante fractures thoracolombaires, la plupart compliquées de troubles neurologiques (32), ont été ostéosynthésées par cadre de Hartshill-Dove. La configuration de ce cadre explique une plus grande rigidité que deux tiges séparées de Luque. Avec ce type de matériel, on ne peut faire que des montages en neutralisation, sans possibilité de compression ni de distraction. Quand il y a trouble neurologique, une large laminectomie, voire une décompression postéro-latérale, précède l'ostéosynthèse. On donne au cadre le galbe de profil désiré; les fils doubles ont été les seuls moyens d'instrumentation utilisés; le nombre de niveaux instrumentés dépend : du segment opéré (7 niveaux en thoracique contre 4 ou 5 en lombaire) et du type de lésion (plus de segments instrumentés pour les translations ou les compressions-distractions que pour les compressions pures). La greffe postérolatérale ne sera localisée qu'en regard de la fracture. Les cyphoses locales et régionales sont corrigées de plus de 50 %; les translations sont corrigées 16 fois/19. Une seule aggravation neurologique est notée dans la série : elle n'est pas due au passage des fils mais à un hématorachis secondaire. Pour éviter les lésions neurologiques iatrogènes, il faut opérer sous monitorage médullaire, réaliser de larges fenêtres et passer les fils métalliques selon les principes techniques décrits. Les meilleures indications de ce matériel très simple d'utilisation sont : en thoracique : toutes les fractures compliquées de troubles neurologiques; s'il n'y a pas de trouble neurologique, les translations, les lésions étagées, les cyphoses vertébrales supérieures à 30°, l'association à une fracture du sternum sont les meilleures indications. En lombaire : les translations et les compressions-distractions. Dans les compressions pures, il faut associer un vissage pédiculaire ou un temps d'arthrodèse antérieure.

    Notes: Summary Between 1985 and 1990, 68 patients with cervical radiculopathy due to soft disc herniation were treated by anterior cervical discectomy without interbody fusion. Eleven patients were unavailable for follow-up examination. The mean follow-up was 23 months (range 12–54 months). Both clinical and radiographic follow-ups were done, and 92% of the patients was found to have excellent or good clinical results. Radiographic follow-up revealed that 34% had fused spontaneously and 66% developed fibrous healing of the disc space with an average range of mobility of 2.07 deg. All patients were shown to be stable on flexion-extension films. Complications included two transient CSF leaks. No neurologic deficits arose. One patient was reoperated and fused for intractable residual neck pain. We conclude that anterior cervical discectomy without interbody fusion is a simple, safe and effective procedure for patients with soft disc herniation.
