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.     

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.     

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.     

胸腰椎肿瘤全脊椎切除术后的重建方式

目的:探讨胸腰椎肿瘤全脊椎切除术后脊柱稳定性的重建方式。方法:1993￣2003年我院治疗各类胸腰椎(T5￣L5)肿瘤患者72例,其中全脊椎切除、随访2年以上、没有肿瘤复发和转移且有完整影像学资料者12例,骨巨细胞瘤9例,单发浆细胞性骨髓瘤2例,非何杰金氏淋巴瘤1例。一期前后路联合全脊椎切除11例,次全脊椎切除1例,以5种不同方式重建,分别为前路内固定加后路短节段经椎弓根内固定(ASP)5例、前路内固定加后路多节段Luque环内固定(AMP)4例、单纯后路短节段经椎弓根内固定(SP)1例、单纯后路多节段经椎弓根内固定(MP)1例、单纯前路内固定(A)1例。观察术前、术后即刻及末次随访时矢状面Cobb角度变化、植骨融合情况、有无植骨骨折及下沉等并发症。结果:随访2.5￣13年,平均6.6年。ASP方式重建的5例患者矢状面Cobb角丢失0°～7°,平均2.4°,植骨全部融合,无植骨骨折,1例因术中损伤终板而出现人工椎体轻度下沉。AMP方式重建的4例患者矢状面Cobb角丢失0°～9°,平均5°,植骨全部融合,无植骨骨折或下沉;其中1例术后1.5年植骨融合后取出后方固定,仅保留前方固定,出现植骨骨折及后凸畸形。SP或MP方式重建的2例患者矢状面Cobb角分别丢失12°和13°,植骨块均骨折。次全脊椎切除A方式重建的1例患者矢状面Cobb角无丢失,植骨融合且无植骨骨折及下沉。结论:本组病例较少,但初步可以看出ASP和AMP是全脊椎切除后坚强的重建方式,能够使植骨顺利融合,防止Cobb角度丢失。但ASP能够减少固定节段、保留运动单元,是更好的固定方式。SP和A不宜单独应用于全脊椎切除后稳定性重建。     

Spontaneous spinal epidural hematomas: is the role of dural arteriovenous malformations underestimated?

Two recent observations of spinal epidural hematomas (SEH) are presented: one of them was associated with iatrogenic coagulopathy, the other, apparently spontaneous, required reoperation for early recurrence and was finally attributed to ruptured epidural arteriovenous malformation missed during the first procedure. Both patients underwent complete recovery. Although modern neuroimaging provides quick, noninvasive, and sensitive assessment of spinal epidural bleeding, we believe that preoperative spinal angiography is indicated in spontaneous SEH with subacute clinical course. Demonstration of underlying vascular anomaly would allow better surgical planning, complete obliteration of abnormal vessels, and prevention of recurrences. Essential epidemiological, pathogenetical, and clinical aspects of SEH are reviewed.     

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.
