Abstract PDF: PURPOSE
The aim of this study is to decide the optimal level of fusion with comparing the results between the short segment fusion and long segment fusion treated with pedicle screw instrumentation, including fractured vertebra in thoracolumbar junctional fractures.
MATERIALS AND METHODS
From February 2000 to November 2009, fifty three patients with junctional fracture of thoracolumbar spine were treated with pedicle screws and posterior fusion at our hospital. They were divided into two groups, the short segment group and long segment group. Preoperatively, immediate postoperative and last follow-up lateral radiological evaluation was done by measuring the correction and loss of segmental kyphosis, wedge angle, body compression rate and instrumented vertebra angle. In addition, operation time and amount of intraoperative bleeding were measured.
RESULTS
There were no significant differences of statistical analysis regarding the radiological variables between the two groups, especially the loss of corrected segmental kyphosis, wedge angle, body compression rate and instrumented vertebra angle (p>0.05). However, operative time in the short segment group (234 minutes) was shorter than the long segment group (284 minutes), and there was statistical significance (p=0.002).
CONCLUSION
We recommend the short segment transpediculr instrumentation one level above and one level below, including the fractured vertebra for thoracolumbar junctional fracture with 6 points or less of the load-sharing score.

The Relationship between Progression of Body Collapse and MRI Findings in Osteoporotic Stable Thoracolumbar Fractures: Young Do Koh, Jong Seok Yoon, Ji Young Hwang, Hyun Sik Park; J Korean Fract Soc 2008;21(4):304-311. Published online October 31, 2008; DOI: https://doi.org/10.12671/jkfs.2008.21.4.304

PURPOSE
To find out the relationship between the initial Magnetic Resonance Image (MRI) findings and the progression of vertebra collapse when treated with Jewett brace in osteoporotic stable thoracolumbar fractures.
MATERIALS AND METHODS
We divided 38 cases of 37 patients of thoracolumbar osteoporotic stable thoracolumbar fractures who were treated with Jewett brace into two groups. One group was composed of those body collapse progressed more than 10% compared with the initial state, and the other group less than 10%. We analyzed the relationships between the progression of collapse and the superior endplate fractures, the fracture line extending to posterior cortex, the size of bone marrow edema, the signal intensity on T1 and T2 weighted MR images, the presence of paravertebral hematoma, and the degree of posterior extensor muscle atrophy using MR images.
RESULTS
The body collapse was more likely to progress when there was superior endplate fracture, when it showed larger size of bone marrow edema on T1 weighted image, and transverse low signal on T2 weighted image. But extending of fracture line to posterior cortex, presence of paravertebral hematoma, and degree of posterior extensor muscle atrophy did not show any statistical correlations to progression of collapse.
CONCLUSION
The body collapse is more likely to progress when there was superior endplate fracture, larger low signal on T1 weighted image and low signal on T2 weighted image at initial MRI treated with Jewett brace.

Abstract

PURPOSE
To evaluate the safety and usefulness of the short-segment posterior instrumentation and fusion in the treatment of thoracolumbar spine fractures.
MATERIALS AND METHODS
Forty-two patients were treated by short-segment pedicle screw instrumentation and fusion between Oct. 1998. and Jan. 2004 by single surgeon. All patients were treated posteriorly and all the pedicle screws are monoaxial. Intraoperative rod bending and fixation technique was used to reduce the collapsed vertebral body and correct the kyphotic angle. The follow up duration is mean 2.1 year (1~6 year). The mean age is 40.2 year (18~60 year) old. The fractures were classified by Denis' classification and Load-Sharing Classification. Preoperative and postoperative changes of kyphotic angle and vertebral body height were measured. Denis' Pain Score and Work scales, Frankel neurologic grade were obtained during follow-up evaluation for patients.
RESULTS
All the cases got solid bony union. Mean Load-Sharing Score was 7.3. Clinical results were good. The mean kyphotic angle was preoperatively 14.5 degree, immediate postoperatively 7.5 degree, and last follow up 9.2 degree. The mean anterior vertebral heights s were 60.8% preoperatively, 83.4% immediate postoperatively, and 79.5% last follow up. There was only one case of screw breakage but no revision operation due to loss of reduction. All the cases showed satisfactory clinical results.
CONCLUSION
This study suggest that short-segment instrumentation and fusion using pedicle screw system for thoracolumbar spine fractures could lead to good results, if comminution of vertebral body is considered in the selection of approach.

Abstract PDF

PURPOSE
To analogize the result of the test through explaining the correlation of bone mineral density (BMD) test value between proximal femur and lumbar spine.
MATERIALS AND METHODS
It is based on 59 cases who visited the out-patient department. They were classified into two groups by age, group I (55~59 yr) and II (60~64 yr). Then we evaluated the average and the degree of correlation between the two groups and analyzed the correlation of the two sites according to the T & Z-score through the regression analysis.
RESULTS
In T-score, the correlation between L (independent variable, lumbar) and H (dependent variable, femur) indicated that L = 0.751 xH -0.195 for group I and L = 0.912 xH+0.31 for group II. In Z-score, the correlation was L = 0.647 xH -0.656 for group I and L = 0.897 xH -0.481 for group II.
CONCLUSION
It is regarded that there will be a clinical availability which can analogize the result of a part by using the result of the other part.

Abstract PDF: PURPOSE
To investigate the MR findings of structures injured in the burst fractures of thoracolumbar spine.
MATERIALS AND METHODS
Twenty-one patients who had thoracolumbar burst fractures with posterior ligament complex injury on MRI were studied. For the evaluation of stability of fractures, we used the scheme described by Oner et al. We identified the state of posterior ligament complex on surgery.
RESULTS
The MRI findings of ALL were state 1 in four, state 2 in fourteen, and state 3 in three. Those of PLL were state 1 in twelve, state 2 in six, and state 3 in three. The findings of posterior ligament complex were state 2 in one, state 3 in three, and state 4 in seventeen. The endplate state 1 was in four, state 2 in six, state 3 in seven, and state 4 in four. The disc state 1 was in twelve, state 2 in six, state 3 in two, state 4 in one. The vertebral body involvement state was 1 in four, state 2 in nine, and state 3 in eight. The injuries of posterior ligament complex were confirmed intraoperatively in all twenty-one patients.
CONCLUSION
We recommend the use of MRI to evaluate stability of fractures and state of posterior ligament complex in thoracolumbar burst fractures.

Fracture of Vertebral Body in Flexion-Distraction Injury of Thoracolumbar Spine: Young Do Koh, Jong Oh Kim, Yeo Hon Yun, Jae Doo Yoo, Jun Mo Jung; J Korean Soc Fract 2003;16(2):262-269. Published online April 30, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.2.262

Abstract PDF

PURPOSE
To evaluate the configuration of vertebral body fractures in flexion-distraction injuries of thoracolumbar spine.
MATERIALS AND METHODS
We investigated the location of fractures, anterior or posterior vertebral body height, kyphotic angle of injured segments, canal encroachment and severity of comminution on radiologic examinations of 21 cases.
RESULTS
There were 11 compression fractures and 9 burst fractures. 85% of fractures were located in the inferior vertebrae of injured segments. Anterior vertebral height decreased by 27% on average with decrease of 18% in compression fractures and 40% in burst fractures. Posterior height decreased by 1% on average with increase of 1% in compression fractures and decrease of 4% in burst fractures. The average kyphotic angle of injured segments was 19.5 degrees with 15.4degrees in compression fractures and 26.8 degrees in burst fractures. The canal encroachment in 9 burst fractures was 27% on average, and the comminution of vertebral body was mild in 74%.
CONCLUSION
The fracture of vertebral body in flexion-distraction injuries of thoracolumbar spine was very common, and located on the inferior vertebrae of injured segment. The decrease of vertebral height, canal encroachment and severity of comminution was relatively less than the estimated from mechanism of injury, with offset effect of distraction force.

Posterior Short Segment Instreumntation and Fusion for the Unstable Thoracolumbar Spine Fracture: A Comparative Study: Ki Tack Kim, Gyu Pyo Hong, Dae Woo Hwang, Sang Un Lee, Sang Wook Bae; J Korean Soc Fract 2000;13(2):352-360. Published online April 30, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.2.352

Abstract PDF: INTRODUCTION : In treating of acute unstable thoracolumbar spine fractures, current trend is a toward short segment instrumentation to spare the motion segments. Many authors reported the result of short instrumentation and fusion, but there have been few reports about the effect of additional screw fixation at fractured vertebra in posterior short segment instrumentation and fusion. Therefore, the objective of this study is to compare the results of treatment between with/without screw fixation at the fractured vertebra in posterior short segment pedicle screw fixation. MATERIAL AND METHODS : Twenty-three patients with unstable thoracolumbar spine fractures were treated with posterior short segment instrumentation and fusion. Eleven cases classified into group A were not fixed at the fractured vertebre. They were followed up to average 45 months(24-79). Twelve cases classified into group B were treated with screw fixation at the injured vertebra and followed up to average 38 months(14-78). Authors evaluated the radiologic assessment, such as wedge angle of fractured body, local kyphotic angle and wedge index(the ratio of anterior body height to posterior body height), the neurologic assessment by Frankel grade system and functional assessment by Denis system.
RESULTS
: There was no complication resulted from additional pedicle screw fixation at fractured level. In rediologic assessment, wedge angle were measured at preoperative, postoperative and last follow-up time as follows; in group A, 22.2degrees -11.3degrees -14.1degrees and in group B, 19.5degrees -8.8degrees -9.8degrees . The local kyphotic angle measured were 17.9degrees -7.0degrees -14degrees in group A and 17.1degrees -6.3degrees -7.9degrees in group B. The wedge index were 42.9%-22.6%-28.5% in group A and 40%-19.5%-22.4% in group B. At last follow-up time, eight eases showed Frankel grade E and three cases showed grade D in group A, and all cases of group B were Frankel E. Denis pain score were satisfctory in all of both group and Denis work score were also satisfactory in two group except one case of group A.
CONCLUSIONS
: Additional screw fixation at fractured verteba did not cause any complication. There was no significant difference in reduction rate between two groups(P>0.05), but group B showed better maintenance of correction of kyphotic deformity than that of group A(P<0.05). In conclusion, it seems that additional screw fixation at fractured level may be better method in maintaining asgittal alignment and decreasing the risk collapsing of body.

The Change of Kyphotic Angle and Anterior Vertebral Height after Posterior or Posterolateral Fusion with Transpedicular Screws for Thoracolumbar Bursting Fractures: Jae Sung Ahn, June Kyu Lee, Deuk Soo Hwang, Young Mo Kim, Won Jung Kim, Kyu Hwan Byun; J Korean Soc Fract 1999;12(2):379-387. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.379

Abstract PDF

The purposes of this study are to make an operative treatment option of thoracolumbar burst fractures by the degree of initial kyphotic deformity or by the degree of initial loss of anterior vertebral height. We analyzed sixty-three cases of one segmental thoracolumbar bursting fractures treated surgically by posterior or posterolateral fusion with short segmental transpedicular screws fixation method using Diapason or CD from January, 1992 to October, 1996. Indications of operative treatment were that the degree of initial kyphotic deformity was above 15degreesor initial loss of anterior vertebral height was above 30%. Minimum follow-up period was 12 months and the results were as follows : 1. Entirely, mean kyphotic angle was 21.6degreesinitially, 11.3degreespostoperatively and 14.2degrees at the end of follow-up. Mean anterior vertebral height was 59.6% initially, 83.8% postoperatively and 80.8% at the end of follow-up. So 10.3degrees , 24.2% was corrected postoperatively and loss of correction was 2.9degrees , 3% at the end of follow-up. 2. In the respect of the degree of initial kyphotic deformity, when compared above 30degrees with below 30degrees , loss of correction was 7.3degrees , 1.4degrees at the end of follow-up respectively and this result had significant difference between these two groups statistically. 3. In the respect of initial loss of anterior vertebral height, when compared above 55% with below 55%, loss of correction was 7.7%, 2.2% at the end of follow-up respectively and this result had significant difference between these two groups statistically. 4. In the respect of time interval from injury to operation, when compared within 2 weeks with after 2 weeks, respectively loss of correction was 1.7-2.2degrees , 3-3.9% and 4.1degrees , 6.7% at the end of follow-up and this results had significant difference between these two groups statistically. These data suggested if initial kyphotic angle is below 30degrees or initial loss of anterior vertebral height less than 55%, short segmental transpedicular screw fixation provide sufficient stability but if initial kyphotic angle is above 30degrees or initial loss of anterior vertebral height is above 55%,additional anterior interbody fusion may be considered.

Nonoperative Management of Stable Thoracolumbar Fracture with Bracing in Old Age: Jong Oh Kim; J Korean Soc Fract 1996;9(3):750-758. Published online July 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.3.750

Abstract PDF: Fourteen neurologically intact patients with stable fractures at the thoracolumbar junction above 60yrs old age were treated with early ambulation in a total contact orthosis, Jewett Brace, Knight-Taylor Brace and had followed up greater than one year. Spinal orthosis have been traditionally used in the management of thoracolumbar junction treated with or without surgical stabilization However, the orthotic treatment modality in the management of spinal fractures remain subjective, especially old age. since few objective data are available on the effectiveness of orthosis in stabilizing injuried segments. At minimum follow up of one year, an overall outcome evaluation involved verbal numerical scale ( VNS ) and radilogical assessment. Approxiamately 80% of the patient had under 3 points in the verbal numerical scale, serial roentgenograms documented significant progressing in body collapse which averaged 9.6% compression,5.2 in Cobbs angle, not correlate with type of brace. Mainly body collapse and increasing Cobbs angle at the fracture site developed within posttraumatic 3 months. Degree of osteoporosis did not correlate with change in deformity. Initial radiographic severity of injury or residual deformity following closed management did not correlate with symptoms at follow-up. This pattern of results suggested comportable brace treatment such as Jewett and Knight-Taylor Brace, as the preferred treatment in stable thoracolumbar fracture in old age.

Comparative Study of Radiologic Changes after Conservative Treatment in Compression fracture and Stable Bursting Fracture of Thoracolumbar Spine: Ho Young Sun, Jung Woung Lee, Sang Don Jung, Jae Young Cho, Deok Young Yoon; J Korean Soc Fract 1995;8(3):667-674. Published online July 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.3.667

Abstract PDF: The diagnosis and management of thoracolumbar spine fracture have been progressrd greatly, because CT and MRI increase the apprehension to thoracolumbar fracture. Middle dolumn was known to be important factor in determining fracture stability, according to "Three column concept by Denis and McAfee." From Jan. 1990 to Jan. 1994 we have managed 63 cases of thoracolumbar compressive fracture and stable burst type thoracolumbar wpine fracture nonoperatively Clinical and radiologic results(kyphotic angle, wedging angle) were evaluated according to fracture pattern. We obtained the following results; 1. The change of kyphotic angle in stable burst fracture is more severe than compressive fracture. 2. The change of wedging angle in stable burst fracture is more severe than compressive fracture. 3. Clinical results of stable bursting fracture was worse than compressive fracture. We concBuded that stable bursting thoracolumbar fracture need more aggressive management.
