Roentgenographic and biomechanical analysis of lumbar fusions: a canine model

An animal model of anterior and posterior column instability was developed to allow in vivo observation of bone remodeling and arthrodesis after spinal instrumentation. Various combinations of spinal fusions and instrumentation procedures were performed after an initial anterior and posterior destabilizing lesion was created at the L5-L6 vertebral levels in 35 adult beagles. After 6 months of postoperative observation, there was improved probability of achieving a spinal fusion if spinal instrumentation had been used. All biomechanical testing was performed after removal of instrumentation to test the inherent stiffnesses and quality of the spinal fusions. The fusions performed in conjunction with instrumentation (group V = Harrington instrumentation and posterolateral fusion; group VI = Luque instrumentation and posterolateral fusion) demonstrated the greatest axial rotation stiffnesses (group V, p less than .05); axial compressive stiffness (group V, p less than .05); and flexural stiffness (group VI, p less than .05). The results show that a spinal fusion can be more reliably achieved and will be more rigid if it is accompanied by spinal instrumentation.

Comparison of sprotte and Quincke needles with respect to spinal fluid leakage using artificial spinal cord

Purpose This research investigated whether the Sprotte needle causes less leakage of CSF than the Quincke needle in the artificial spinal cord. Methods The changes in intradural pressure, extradural pressure, and leaked volume of CSF were evaluated following puncture with Sprotte and Quincke needles in the artificial spinal cord. Results The decrease in intradural pressure was 9.7±1.8 mm H₂O with the Sprotte needle and 20.5±2.7 mm H₂O with the Quincke needle (P<0.05). The volume of leakage of artificial CSF was 2.0±0.3 ml with the Sprotte needle and 3.3 ±0.3 ml with the Quincke needle (P<0.01). The extradural pressure increase was 166.1±8.2 mm H₂O with the Sprotte needle and 186.8±13.2 mm H₂O with the Quincke needle (P<0.05). Conclusion The Sprotte needle produces less CSF leakage than the Quincke needle.     

A thoracic and lumbar spine injury severity classification based on neurologic function grade, spinal canal deformity, and spinal biomechanical stability

BACKGROUND CONTEXT: Current well regarded thoracic and lumbar spine injury classifications use mechanistic and anatomical categories, which do not directly rely on quantifiable management parameters. Their clinical usefulness is not optimal. PURPOSE: Formulate an injury severity based classification. STUDY DESIGN/SETTING: This retrospective investigation studied patients who suffered thoracic and lumbar spine injuries, and examined the following three quantifiable parameters: 1) neurologic function grade; 2) spinal canal deformity; 3) biomechanical stability. These parameters are the primary clinical indications for management decisions. PATIENT SAMPLE: One hundred twenty-six consecutive patients with spinal trauma admitted to a level 1 tertiary trauma center from January 1997 to November 2005 were enrolled in this study. OUTCOME MEASURES: Spine injury severity was independently scored on three parameters: 1) neurologic function impairment grade according to the modified Frankel grading method and the American Spinal Injury Association (ASIA) function scale; 2) spinal canal deformity from translation and intrusion, measured as percent canal cross-sectional area compromise; 3) failure of five possible biomechanical functions in Denis's three anatomic columns, and a sixth group of unstable deformities. All three columns contribute to tensile function. Only the anterior and middle columns provide compression load-bearing function. A combination of three or more column biomechanical function failure or an unstable deformity renders the injury unstable. METHODS: Five fellowship-trained spine surgeons from one institution took part in the study. Hospital medical records, including admission history and physical examination, discharge summary, and operative report (if surgery was performed), were examined for neurologic deficit. Plain radiographs, computed tomographic scans and magnetic resonance imaging were assessed for canal compromise and biomechanical function status. RESULTS: Injuries were located from T3 to L5, 58% of which were at the thoracolumbar junction (T11-L2). Neurologic impairment occurred in 45% (57/126) of patients, with 19 complete paraplegias (Frankel grade A). The average spinal canal cross-sectional area compromise was 56.1% in neurologically impaired and 14.2% for patients who where neurologically intact. The number of tensile element failure patients in neurologically impaired versus intact are as follow: tri-columns 22/4; two columns 16/8; one column 11/17; all columns intact 8/40. Load-bearing element failed in 55/57 neurologically impaired and 63/69 intact patients. Sixty-seven patients had spinal reconstructive surgery. Their average instability profile score was 4.4 out of 6, and canal compromise score was 3.3 out of 5. CONCLUSIONS: A clinically useful thoracic and lumbar spine injury classification should be based on parameters that are the primary indications for management decisions. The same parameters should be injury severity quantifiable as to guide treatment. In this study we introduced spinal canal deformity and column biomechanical functions as quantifiable parameters in thoracic and lumbar injury severity classification. Validation of this method is beyond the scope of this preliminary study.     

Surgical decompression: a life-saving procedure for an extensive spinal epidural abscess

Extensive spinal epidural abscesses (SEAs) carry a high mortality rate. Traditionally they are treated non-operatively with longterm antibiotics and/or surgical decompression, but there is a continuing debate as to whether they should be managed by emergency surgical decompression. However, such decisions are made in the light of the clinical setting. We report the successful management of a female patient who presented with features of upper cervical cord compression and later developed septic shock and multisystem failure. Surgical decompression of the cervical spine and irrigation of the epidural space with a paediatric catheter was performed followed by tricortical strut grafting and plating. At review, 36 weeks after surgery, the patient remained asymptomatic, having made full neurological recovery. The purpose of this report is to highlight the importance of emergency surgical intervention for extensive SEA in the presence of progressive neurological loss associated with multisystem failure.     

Extradural spinal meningioma: case report

Objectives

We report a case of purely extradural spinal meningioma and discuss the potential pitfalls in differential diagnosis.

Background

Spinal meningiomas account for 20–30% of all spinal neoplasms. Epidural meningiomas are infrequent intraspinal tumors that can be easily confused with malignant neoplasms or spinal schwannomas.

Case

A 62-year-old man with a previous history of malignant disease presented with back pain and weakness of the lower limbs. Magnetic resonance imaging revealed a well-enhanced T4 intraspinal lesion. The intraoperative histological examination showed a meningioma (confirmed by postoperative examination). Opening the dura mater confirmed the purely epidural location of the lesion. The postoperative course was uneventful with no recurrence 12 months after surgery.

Conclusion

Purely extradural spinal meningiomas can mimic metastatic tumors or schwannomas. Intraoperative histology is mandatory for optimal surgical decision making.     

扩大半椎板切除术治疗颈脊髓损伤

OBJECTIVE: To treat cervical spinal cord injury (SCI) accompanied with narrowing spinal canal by expanded hemilaminectomy. METHODS: From 1995 January to 1998 April 51 patients of cervical SCI were treated by expanded hemilaminectomy. Spinal injury classified in to 3 types: no fracture-dislocation (39 patients) fracture dislocation at the lower cervical spine (11), and burst fracture (1). The types of SCI included central cord injury (18 patients) incomplete cord injury (19), and complete cord injury (14). MR imaging in 23 patients showed degenerative changes with normal intensity of the cord in 14 patients, multiple level hyperintensity in 3, cystic changes in 3, myelomalasia in 3, and cord brocken in 1. Expanded hemilaminectomy was performed in 24 hours in 3 patients, in 48 hours in 9, in one week in 2, after one week in 35, and after one year in 2. The left or right laminae were removed from C(7) to C(3) in 42 patients, C(3) - T(1) in 3, C(2) - C(7) in 2, C(3) - C(6) in 3 and C(4) - C(7) in 3. Hemilaminectomy was expanded lateral to the inner of apophyseal joint and medial to the inner lamina beneath the spinal process. RESULTS: Follow-up lasted for 1 year and 7 months. Six patients with complete cord injury had of the no recovery lower extremity but recovery of the brachialis and extensor radial longus. 12 patients of central cord injury had full recovery except intrinsic muscles of the hand (5). They operated were on 2 weeks after injury. 17 patients of incomplete cord injury recovered to Frankel IV. CONCLUSIONS: Expanded hemilaminectomy is indicated for patients of cervical SCI with narrowing spinal canal or without fracture dislocation. Best results can be obtained in patients of central cord injury, and incomplete cord injury. Even in complete cord injury, 1 - 2 forearm muscle may recover (24.8%), securing a pinch grip reconstruction.     

胸腰椎骨折伴脊髓损伤治疗进展

脊柱骨折伴脊髓损伤的治疗，一直是脊柱外科关注的课题，随着对神经损伤的病理生理研究深入和手术方法的改进，对其治疗方法和观点也有了进一步的发展。本文就胸腰椎骨折伴脊髓损伤治疗方面的进展进行综述。     

Post operative infections of the spine: technique,indications and results of the surgical treatment - A retrospective study of 90 cases

Post operative infection in spine surgery is a well known complication. The authors studied a series of 90 patients in accordance with an homogenous strategy based on the excision of necrotic and infected tissues, associated with appropriate antibiotics.The results are analyzed according to the degree of infection (which is based on the type of germs and their associations), and type of patients, the delay in diagnosis and the anatomical extension of the infected lesions.Making a difference between superficial and deep infection is of no therapeutic value and may lead to wrong and inadequate treatment.One must separate the common infections (which are due to germs as staphylococcus aureus or others from the urinary or digestive tract), and severe infections (which are either due to a per operative massive and deep contamination, or associated with patient's poor general condition).This series is mainly about posterior approaches to the spine, with or without osteosynthesis. Technical problems for treatment depend on the site of infection, particularly at the thoracic kyphosis level, or at the lumbar level where the muscle necrosis can be extensive. At the cervical level, the infection of an anterior approach mandates a check on the respiratory and digestive tracts.Removing the osteosynthesis is not mandatory in post operative spinal infections, as it may induce severe mechanical destabilization. An anterior approach is not necessarily required in the case of a posterior infection, except with massive contamination of an anterior graft. In some cases, posterior lumbar interbody fusion can lead to the indication for anterior cage removal.Pseudarthrosis of an infected spine, initially treated to obtain fusion, is still the worst complication. In case of previous posterior infection, even a severe one, fusion can still be obtained through a secondary anterior or posterior approach for grafting, with or without osteosynthesis.In this series, there was no neurological complication due to infection.However, eight diceases occured in weak patients with neurological involvement. This points out the importance of the general treatment associated with the surgery, and the necessity of a thorough assessment. a thorough assessment.Résumé Les infections post-opératoires représentent une complication largement documentée dans le domaine de la chirurgie du rachis. Les auteurs étudient une série de 90 patients traités selon une stratégie homogène basée sur l'excision des tissus nécrosés et infectés associée à l'utilisation d'un traitement antibiotique adapté. Les résultats sont analysés en fonction du degré d'infection (basé sur le type de germe et leurs associations) de l'état des patients, du délai pour le diagnostic et de l'étendue anatomique des lésions infectieuses. L'opposition entre infection superficielle et profonde semble sans intérêt sur le plan thérapeutique et peut conduire à un traitement insuffisant ou mal adapté.Il est important de séparer les infections classiques (qui sont dûes à des germes comme le staphylocoque doré ou d'autres germes provenant de la sphère urinaire ou digestive) et les infections sévères (qui sont soit dûes à une contamination per-opératoire massive et profonde ou associées à des patients dont létat général est déficient).Cette série est principalement basée sur les abord postérieurs du rachis avec ou sans ostéosynthèse. Les problèmes techniques pour le traitement dépendent du site de l'infection: aux niveaux thoracique et lombaire, la nécrose musculaire peut être très extensive. Au niveau cervical, l'infection d'un abord antérieur impose de vérifier l'intégrité du tractus aéro-digestif.L'ablation initiale du matériel n'est pas nécessaire dans beaucoup de cas d'infections post-opératoires car elle peut induire des destabilisations sévères et des complications mécaniques supplémentaires. Un abord antérieur n'est pas forcément nécessaire en cas d'infection postérieure mises à part les contaminations massives d'une greffe antérieure ou une infection d'une cage intervertébrale réalisée pour une fusion intersomatique par voie postérieure.La pseudarthrose des greffes sur un rachis infecté qui a été traité initialement pour obtenir une fusion reste encore la plus sévère des complications. Dans les cas d'infections postérieures même sévères, la fusion peut être encore obtenue secondairement grâce à un abord antérieur ultérieur ou même un abord postérieur pour des greffes complémentaires avec ou sans ostéosynthèse.Dans cette série, les auteurs ne signalent aucune complication neurologique dûe à l'infection. Néanmoins, 8 décès sont à déplorer chez des patients fragiles avec signes neurologiques initiaux. Ceci souligne l'importance du traitement général associé à la chirurgie et la nécessité d'un bilan complet de ces malades.EBJIS Congress, Leuven
