Treatment of spinal fractures in children and adolescents: long-term results in 44 patients.

STUDY DESIGN: The authors examined a case series of patients younger than 16 years who had sustained a traumatic spine injury. OBJECTIVES: To evaluate clinical and radiologic findings and the effectiveness of conservative versus surgical treatment at long-term follow-up. SUMMARY OF BACKGROUND DATA: Although injuries to children have received increasing coverage in the literature over the last several years, few reports have focused on the long-term results of conservative versus surgical treatment. METHODS: Forty-four patients who had sustained a traumatic spine injury at the average age of 14 years (range 3-16 years) were clinically and radiographically reviewed. The fractures were separated into three groups: stable (n = 20) and unstable (n = 13) injuries without cord lesion and fractures with spinal cord lesion (n = 11). Mean follow-up was 18 years (range 9-23 years). RESULTS: Conservative treatment was successful in all stable fractures, whereas it failed in the unstable injuries. The surgical treatment stabilized without significant deformity in five of the seven unstable fractures. Of 11 with spinal cord injuries, the 4 children conservatively treated developed a severely progressive, paralytic scoliosis. Only three of the seven surgically treated patients were stabilized without any deformity at follow-up. CONCLUSION: In children and adolescents, conservative treatment is an available option for stable fractures without neurologic lesion. Early surgical treatment (instrumentation and fusion) is mandatory for unstable fractures and injuries associated with spinal cord lesion. In children, a traumatic spinal cord lesion may develop a deformity that is mainly scoliotic, kyphotic, or lordotic in >90% of the cases.

Reliability of magnetic resonance imaging in detecting posterior ligament complex injury in thoracolumbar spinal fractures.

STUDY DESIGN: Prospective study of 34 patients with thoracolumbar spinal fractures. OBJECTIVES: To assess the reliability of magnetic resonance imaging (MRI) for posterior ligament complex injury in thoracolumbar spinal fractures. SUMMARY OF BACKGROUND DATA: Some researchers have studied posterior ligament complex injury in spinal fracture using MRI. However, most did not evaluate the findings of MRI compared with the operative findings. METHODS: Thirty-four patients with thoracolumbar spinal fracture were evaluated by palpation of the interspinous gap, plain radiography, and MRI before operation. In addition to conventional MRI sequences, a fat-suppressed T2-weighted sagittal sequence was performed. Surgery was performed by a posterior approach. During the operation, posterior ligament complex injury was carefully examined. RESULTS: A wide interspinous gap was palpated in 14 patients and was found in 21 patients on plain radiography. Magnetic resonance imaging raised suspicion of injury to the posterior ligament complex in 30 patients. According to interpretation of MRI, injury to the supraspinous ligament was suspected in 27 patients, the interspinous ligament in 30 patients, and the ligamentum flavum in 9 patients. There were 28 supraspinous ligament injuries, 29 interspinous ligament injuries, and 7 ligamentum flavum injuries in operative findings. There was a significant relation between MRI interpretation and operative findings. CONCLUSION: A fat-suppressed T2-weighted sagittal sequence of MRI was a highly sensitive, specific, and accurate method of evaluating posterior ligament complex injury. Based on the results of this study, a fat-suppressed T2-weighted sagittal sequence of MRIs is recommended for the accurate evaluation of posterior ligament complex injury and would be helpful in the selection of treatment options.

Cervical spinal fractures: CT detection.

Although computed tomography (CT) is commonly used in addition to plain radiographs to evaluate cervical spinal fractures, it may fail to detect some clinically significant fractures. Cervical spinal fractures were produced in cadavers, studied with CT, and documented by cryomicrotomy. The CT scans were interpreted independent of the anatomic sections. Pedicle and lateral mass fractures were regularly unrecognized on CT scans. In these cases, widening and hemarthrosis of the adjacent facet joints were evident. A widened facet joint is an indirect sign of an occult cervical spinal fracture.

Ultrasound-guided spinal fracture repositioning, ligamentotaxis, and remodeling after thoracolumbar burst fractures.

STUDY DESIGN: Computed tomography aided evaluation of spinal decompression by ultrasound-guided spinal fracture repositioning, ligamentotaxis, and remodeling after thoracolumbar burst fractures. OBJECTIVES: To determine the necessity of spinal canal widening by ultrasound-guided fracture repositioning for fractures with and without neurologic deficit. SUMMARY OF BACKGROUND DATA: Ultrasound-guided spinal fracture repositioning is an alternative new approach. Reports have varied concerning ligamentotaxis and remodeling. METHODS: Computed tomography aided planimetry of the spinal canal (64 consecutive burst fractures) and neurologic evaluation by Frankel grades. RESULTS: Ultrasound-guided spinal fracture repositioning (n = 37) reduced the stenosis of the spinal canal area from 45% before surgery to 20% after surgery of the estimated original area. Fifteen patients had a primary neurologic deficit, which improved markedly in 11 cases after treatment. Patients with neurologic symptoms had a greater preoperative spinal stenosis than those without. No correlation was seen between the degree of pretreatment spinal stenosis, fracture type, and severity of the neurologic deficit. Ligamentotaxis (n = 27) reduced the stenosis from 30% before surgery to 18% after surgery and remodeling (n = 11) from 25% after surgery to 13% after metal removal. CONCLUSION: Ultrasound-guided fracture repositioning is an efficient method for spinal canal decompression of burst fractures with neurologic symptoms. The marked degree of widening of the spinal canal due to the effects of ligamentotaxis and remodeling may render the reposition of retropulsed fragments unnecessary in cases of fractures without a neurologic deficit.

Thoracolumbar spinal fractures--concepts of treatment.

The treatment of thoracolumbar spinal fractures has evolved significantly in the last 50 years. Clear classification systems now allow physicians to predict which fracture patterns will require surgery and which may be adequately treated non-operatively. These indications, as well as a brief overview of thoracolumbar spinal fracture care, are presented.

Spinal fractures complicating ankylosing spondylitis.

The ankylosed osteoporotic spines of patients with long-standing ankylosing spondylitis are prone to fracture. The spinal trauma is of a trivial nature in many patients and the diagnosis may be overlooked, unless neurologic damage occurs. The fractures most commonly occur in the cervical region and may be multiple. Because of spinal osteoporosis and deformity, radiographic visualization of the fracture site may be difficult. Tomography may be helpful in some patients. Management may be conservative or surgical and is complicated by increased instability of the fracture site, spinal osteoporosis, and deformity. Conservative management of cervical fractures is probably best accomplished by halo traction and body cast. Progression of the neurologic deficit is an indication for surgical intervention.

[Treatment of spinal fractures complicating ankylosing spondylitis].

OBJECTIVE: To study the treatment of spinal fractures in ankylosing spondylitis. METHODS: Nineteen cases of spinal fractures complicating ankylosing spondylitis admitted in our hospital were studied retrospectively. RESULTS: All of 19 cases were up to the diagnosis standards of ankylosing spondylitis. Eleven patients had cervical fracture and 8 had thoracolumbar fracture. Of the patients with cervical fracture, fractures occurred at C(5 - 7) in 9 patients. Of the patients with thoracolumbar injury, stress fractures were seen in 7 patients and all of seven fractures occurred at T(10)-L(2). Sixteen of the 19 patients sustained fractures through three columns of the spine. Nine patients had spinal cord injures; eight of the 9 cases had cervical fracture. All of the 19 patients were treated operatively. Four different surgical procedures were used in patients with cervical fracture; decompression, fusion and stabilization with instrumentation by anterior approach were performed in 9 patients. Of the patients with thoracolumbar fractures, four different operations were performed; fusion by both anterior and posterior approach plus a long posterior instrument were used in 5 cases. Eighteen patients had an average follow-up period of 46.6 months. Nine patients with preoperative neurological deficits improved in 8 and was stabilized in 1. Radiographic evidence of fusion was observed in all of the 18 patients. Two patients suffered neurological deterioration during surgery. One patient died from cerebrovascular infarction. Two patients had pneumonia after the operative procedure. CONCLUSIONS: Spinal fractures in ankylosing spondylitis are associated with a high rate of neurological injury. Shearing fracture usually occurs at the lower cervical spine (C(5 - 7)) and stress fracture at thoracolumbar spine. Most of the fractures involve three columns of spine. Surgical intervention may be indicated in this injury. Fracture union and neurological improvement can be achieved in most patients treated by operation. We suggest that, fusion and stabilization with instrumentation by anterior approach is indicated in most cervical shearing fracture, and a combined fusion by both sides plus a long posterior instrument is probably beneficial in patients with thoracolumbar stress fracture. Complications is not rare after surgery and appropriate preventive measures are necessary for these patients.

Osteoporosis and spinal fractures in men with prostate cancer: risk factors and effects of androgen deprivation therapy.

PURPOSE: We determined the risk factors for osteoporosis and spinal fractures in men with prostate cancer receiving androgen deprivation therapy. MATERIALS AND METHODS: We performed a retrospective analysis of 87 consecutive men with prostate cancer receiving androgen deprivation therapy referred for evaluation of osteoporosis. Data were comprised of lateral thoracolumbar radiographs, bone densitometry, serum biochemistry and a detailed assessment of osteoporotic risk factors. Multivariate regression analysis was used to determine the major risk factors for osteoporosis and spinal fractures. RESULTS: There were 38 (44%) men who were 74.5 years old with radiographic evidence of spinal fractures. They had an initial mean prostate specific antigen of 52.8 ng/ml and had received androgen deprivation therapy for a mean of 39.6 months (95% confidence interval 28.7 to 50.4). Mean spinal (quantitative computerized tomography t-score -4.2) and femoral neck bone mineral densities (dual energy x-ray absorptiometry t-score -2.1) were significantly lower than in men without spinal fractures (p < 0.001 for all measurements). In the regression analysis the duration of androgen deprivation therapy (p = 0.002), serum 25-hydroxyvitamin D levels (p = 0.003) and a history of alcohol excess (defined as more than 4 standard drinks daily, p = 0.04) were the main determinants of spinal fractures. CONCLUSIONS: Prolonged androgen deprivation therapy, low serum 25-hydroxyvitamin D levels and a history of alcohol excess are important risk factors for osteoporosis and spinal fractures in men with prostate cancer.

Epidemiology of incident spinal fracture in a complete population.

STUDY DESIGN: Cross-section observational study of incident spinal fractures using an administrative data-base. OBJECTIVES: To identify and define all patients who have spinal fractures within a complete population. SUMMARY OF BACKGROUND DATA: The true incidence of spinal column and cord injury is not known. Previous studies have been institutional or practice based. Accurate information concerning the magnitude of the spinal injury population and their characteristics may provide more rational basis for public health decision making and resource allocation. METHODS: The study dates were April 1, 1981 to March 31, 1984. Using the Manitoba Health Services Insurance Plan database, all patients with ICD-9-CM coding of 805.x and 806.x (spinal column fracture with and without spinal cord injury) were identified. Incidence rates, age and gender distribution, and ambulatory and hospital contracts were identified. Hospital discharge abstracts were used to classify mechanisms of injury, associated injuries, and length of stay. RESULT: The annual incidence rate of spinal fracture was 64 per 100,000. Two thousand sixty-three patients were identified, with 944 being admitted to the hospital. There were two peaks of incidence occurring in young men and elderly women. Of the hospitalized patients, 182 had cervical injury, 286 had thoracic fracture, and 403 had injury in the lumbosacral spine Associated injuries occurred in 38% of hospitalized patients. Length of stay was an average of 38.5 days. Overall mortality was 41%. Neurologic injury occurred in 122 patients. CONCLUSIONS: Ambulatory care of spine injuries is more common than hospital care. Two peaks of incidence occur-in young men and elderly women. Future decisions for research, public health policy, and resource allocation can be based on these data.

Upper thoracic spinal fractures in trauma patients - a diagnostic pitfall.

The diagnosis of upper thoracic spinal fractures in multiple-trauma patients remains a challenge. The clinical findings are often difficult to detect, especially in the presence of other (extremity) fractures, head injuries or in patients on respiratory support. The findings of chest radiographs and plain spinal films are described in a series of 23 patients with an upper thoracic spinal fracture. Radiographs were retrospectively reviewed by an orthopaedic surgeon and a skeletal radiologist. Fractures were classified according to Magerl and type A1 and A2 compression fractures were excluded. The neurological outcome was assessed using the Frankel scale.Initially, the fracture was missed in 5 patients (22%), mainly due to concomitant life-threatening injuries. Fractures consisted of type A, B and C in one, 10 and 12 patients, respectively. The main findings were: loss of vertical height of vertebra with or without malalignment (21), widened paraspinal line (21), widened mediastinum (4) and no gross abnormalities (2). Neurological lesions were Frankel A, B, C and E in respectively 14, 1, 1 and 7 patients.Upper thoracic spinal fractures are easily missed in patients with multiple injuries. In patients with neurological symptoms CT and/or MRI is required as soon as the general condition of the patient permits this.

Diagnostic value of 3D CT surface reconstruction in spinal fractures.

Our purpose was to evaluate the diagnostic value of three-dimensional (3 D) CT surface reconstruction in spinal fractures in comparison with axial and reformatted images. A total of 50 patients with different CT-proven spinal fractures were analysed retrospectively. Based on axial scans and reformatted images, the spinal fractures were classified according to several classifications as Magerl for the thoraco-lumbar and lower cervical spine by one radiologist. Another radiologist performed 3 D CT surface reconstructions with the aim of characterizing the different types of spinal fractures. A third radiologist classified the 3 D CT surface reconstruction according to the Magerl classification. The results of the blinded reading process were compared. It was checked to see in which type and subgroup 3 D surface reconstructions were helpful. Readers one and two obtained the same results in the classification. The 3 D surface reconstruction did not yield any additional diagnostic information concerning type A and B injuries. Indeed, the full extent of the fracture could be easier recognized with axial and reformatted images in all cases. In 10 cases of C injuries, the dislocation of parts of vertebrae could be better recognized with the help of 3 D reconstructions. A 3 D CT surface reconstruction is only useful in rotational and shear vertebral injuries (Magerl type C injury).

[Multiple noncontiguous spinal fracture].

Twenty-seven cases of multiple noncontiguous spinal fracture were reported. The injury located mostly at thoracolumbar levels, and primary injuries occurred in thorax (n = 13, 50%), second injuries occurred in lumbus (n = 14, 53.8%). The cord function of 12 patients were Frankel A, 5 were C and 4 were D; five patients were normal (Frankel E). The incidence of neurologic injury was significantly different between multiple noncontiguous and contiguous spinal fractures (P < 0.01). There were 17 followed-up cases. Eight were recovered with Frankel 1 degree, 2 with 2 degree and 4 without change. The importance of correct diagnosis is emphasized and it is recommended that total spine radiography be performed as soon as possible.

Lumbar disk pseudotumor: an unusual presentation of lumbar spinal fracture and stenosis.

We present an unusual case of a primary lumbar disk-space mass that presumably developed secondary to a chronic hyperextension spinal fracture associated with spinal stenosis. This injury resulted in the appearance of a lumbar intervertebral disk-space mass or pseudotumor. The pseudotumor most likely resulted from a prior spinal fracture, leading to a fused hyperextension deformity in a patient with underlying chronic degenerative spinal disease.

High bone turnover is associated with low bone mass and spinal fracture in postmenopausal women.

A group of 366 healthy, white postmenopausal women, aged 50-81 years, mean age 66 years, were selected from the screened population of Scandinavians who were part of a multicenter study of the efficacy of tiludronate, a new bisphosphonate, in established postmenopausal osteoporosis. Eighty-eight women had a lumbar spine bone mineral density (BMD) above 0.860 g/cm2, and 278 women had a BMD below 0.860 g/cm2. Spinal fracture was diagnosed from lateral spine X-ray studies and defined as at least 20% height reduction (wedge, compression, or endplate fracture) in at least one vertebra (T4-L4). Bone resorption was assessed by measurement of the urinary excretion of type I collagen degradation products by the CrossLaps enzyme-linked immunoassay (ELISA). Bone formation was assessed by ELISA measurement of the N-terminal-midfragment as well as the intact serum osteocalcin (OCN-MID), thus omitting the influence of the instability of osteocalcin caused by the labile 6 amino acid C-terminal sequence. The women were divided into groups with high or low bone turnover according to the concentrations of urinary Cross-Laps or OCN-MID. Women in the quartiles with the highest concentrations of CrossLaps [519 +/- 119 micrograms/mmol (SD)] or OCN-MID [44.6 +/- 7.5 ng/ml (SD)] had 10-16% lower spinal BMD compared with women in the lowest quartiles (CrossLaps 170 +/- 48 micrograms/mmol (SD), and OCN-MID [22.1 +/- 3.0 ng/ml (SD)] (P < 0.0004). The prevalences of spinal fracture were 25 to 29% in the lowest quartiles, whereas the prevalences in the highest quartiles were almost double-53-54% (P < 0.006). If the women were subgrouped according to spinal BMD and prevalence of spinal fracture, corresponding results were found. Women with a BMD less than 0.860 g/cm2, without or with spinal fracture (n = 136 and n = 142), had 36-43% higher concentration of Cross-Laps (P = 0.0001) and 11-15% higher concentration of OCN-MID (P < 0.02), as compared with women with a BMD above 0.860 g/cm2 and no spinal fracture (n = 84). In conclusion, the results indicate a strong association among high bone turnover, low bone mass, and prevalence of spinal fracture, which supports the theory that high bone turnover is a risk factor for spinal fracture and osteoporosis.

[Spinal fractures in the elderly and their treatment].

Spinal injuries referring to banal falls are common injuries in elderly persons. Up to 55 years of age spinal fractures are more frequent in men while its opposite in older persons. There are two typical lesions: odontoid fracture in the upper cervical spine and compression fracture in thoracolumbar spine. Odontoid fracture is the most frequent lesion in cervical spine in the elderly. This is caused by trabecular structure of dens axis and spine's stiffness in old age. Instable fractures in extension type II are most common. In many cases the instability of the lesion is hidden and can be first seen in functional examination controlled by x-ray. Conservative treatment is efficient in stable lesions type III while there is a high risk for pseudarthrosis in treatment of instable lesions in elderly with Halo Fixateur e.g. We think that the best operation for these fractures is the anterior screw fixation. If this is not sufficient because of low bone mass or early dislocation of the screws a dorsal fusion C1/C2 with trans-articular screwing e.g. should be done. Because of rare symptoms thoracolumbar fractures in osteoporosis are hidden frequently. In many cases it's not easy to distinguish acute lesions from healed fractures or tumor lesions. Neurological deficit is rare. Therefore there are just few compression fractures (A type) that have to be treated operatively. Instable lesions type B and C must be operated as well in the elderly as in the young. Because of low bone mass in elderly the dorsal instrumentation should include more than just the two injured segments. An even more adequate stabilisation is done with an additional vertebral replacement.
