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.

Evaluation of the Patterns of Fractures and the Soft Tissue Injury Using MRI in Tibial Plateau Fractures: Ji Yong Chun, Hee Gon Park, Sung Su Hwang; J Korean Fract Soc 2007;20(4):302-308. Published online October 31, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.4.302

Abstract PDF

PURPOSE
To compare information about fracture type in MRI with simple radiograph in tibial plateau fractures and evaluate tibial plateau fractures type and accompanying soft tissue injury, and evaluate usefulness of MRI in tibial plateau fractures.
MATERIALS AND METHODS
Compared MRI with simple radiograph about Schatzker classification, depression of articular surface and displacement of bone fragment from the 68 examples who checked MRI and we evaluated soft tissue injury around knee joint.
RESULTS
There were 7 examples of Schatzker type change after MRI check. Average depression of articular surface in simple radiograph was 2.93 mm and 4.28 mm in MRI. It increased by 1.35 mm and it was meaningful statistically (p<0.05). There was no significant difference between MRI and simple radiograph of displaced bone fragment (p=0.168). There were 58 (85.3%) cases of soft tissue injury in MRI.
CONCLUSION
MRI can find additional fracture line or articular depression that can't be found in simple radiograph and gives more information about articular depression and soft tissue that is useful in surgical plans. I think preoperative MRI is necessary to better treatment of fracture & treatment of periarticular soft tissue injury in tibial plateau fracture.

Bone & Soft Tissue Injuries Diagnosed by Magnetic Resonance Imaging in Thoracolumbar Fractures: Yong Min Kim, Dong Soo Kim, Eui Seong Choi, Hyun Chul Shon, Kyoung Jin Park, Gi Seok Han, Jae Jung Jeong, Kyoung Il Jeong, Yung Sung Kim; J Korean Fract Soc 2004;17(2):184-190. Published online April 30, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.2.184

Abstract PDF

PURPOSE
To assess diagnostic efficacy of the MRI in thoracolumbar fractures, especially in changes of bone and soft tissue which cannot be documented by other diagnostic tools.
MATERIALS AND METHODS
Among 85 patients managed for thoracolumbar fractures between January 1997 and June 2003, MRI was performed in 30 patients to get more informations. Plain X-ray, CT and MRI of these cases were reviewed retrospectively by two orthopaedic spine surgeons and one radiologist to investigate the informations which only MRI could afford.
RESULTS
14 (46.7%) among 30 patients had occult fractures of vertebrae other than main fracture which had not been diagnosed as fractured. Besides 6 patients who showed distraction of posterior structure on plain X-ray, injury of posterior ligament complex was confirmed by MRI in 12(40%) patients. Additionally, MRI visualized other soft tissue injuries such as intramuscular and subcutaneous hematoma, changes of the spinal cord and intervertebral disc. In 16 among 30 patients, informations achieved from MRI were the most important factors in deciding treatment modality.
CONCLUSION
MRI seems to be efficient in visualizing not only soft tissue injury such as ligament but also occult fractures of additional vertebra in thoracolumbar fractures, therefore MRI seems to be an important diagnostic tool in decision of treatment modalities, especially in cases of uncertain stability.

The Efficacy of MRI in Tibial Plateau Fractures: Hyoun Oh Cho, Kyoung Duck Kwak, Dae Hwan Lim, Sang Min Ahn, Kyung Ku Kang; J Korean Fract Soc 2004;17(2):122-132. Published online April 30, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.2.122

Abstract PDF

PURPOSE
To analysis the efficacy of MRI in assessing fracture configuration and frequency of associated soft tissue injuries in tibial plateau fractures.
MATERIALS AND METHODS
In the plain films and MRI of 47 cases with tibial plateau fractures,every fracture was classified by findings on plain film and MRI respectively according to the Schatzker system and they were compared with each other. The degree of displacement and depression of the fracture fragments were measured on plain film and MRI.
RESULTS
MRI was more accurate in determining the classification of the fracture and measuring the displacement and depression of fragments. Fracture classifications were changed in 12 cases. Especially in Schatzker VI cases, articular step off over 2 mm and articular fragments over 2X2 cm were revealed in detail by MRI. Evidence of internal derangement of the knee was found in 38 (80.8%) cases.
CONCLUSION
Most of the cases with acute tibial plateau fracture were commonly associated with ligamentous and meniscal injuries. MRI can aid in accurate evaluation of tibial plateau fracture patterns and decision of treatment plan.

Comparison of degrees of Depression Between Simple X-ray and MRI in Tibial Plateau Fracture: S W Suh, H C Lim, C Y Huh, W N Moon, D Park, M P Hong; J Korean Soc Fract 2002;15(2):146-151. Published online April 30, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.2.146

Abstract PDF

PURPOSE
The purpose is to analyze the efficacy of the MR images in the diagnosis and the treatment of the tibial plateau fracture, by comparing the amount of depression in the plain radiograph and in the MR images.
MATERIALS AND METHODS
Both the MRI and the plain radiograph were performed in 14 patients from 1997 to March 2001. The Schatzker-fracture type and the amount of joint depression were measured and compared in the plain radiograph and the MR images.
RESULT
In the Schatzker's classification, both type I and II were largest in number. The average amount of joint depression was measured as 1.8 mm by plain radiograph and 5.5 mm by MRI, so the difference was measured as 3.7 mm.
CONCLUSION
In some cases the joint depressions were more than 3 mm by measuring in the MRI, even though the amount of joint depressions were much less by measuring in the plain radiograph. After measuring with MRI, the indication of the surgery may be expanded. In conclusion, as MRI in the tibial palteau fractures can give precise information of the amount and the position, it may help the prediction of the surgical indication and prognosis.

MRI Findings of Stress Fracture in Long Bone: Sung Ho Hahn, Bo Kyu Yang, Seung Rim Yi, Shun Wook Chung, Yang Hee Park, Dong Oh Ko; J Korean Soc Fract 2001;14(2):145-151. Published online April 30, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.2.145

Abstract PDF: PURPOSE
The goal of our study was to evaluate diagnosis and management of stress fracture in long bones using MRI findings. MATERIAL & METHOD: Between May 1995 to May 1999, 40 patients( 45 cases ) were confirmed to have a stress fracture by clinical and radiological findings. All patients were evaluated with clinical, X-ray, bone scan, and MRI findings. The patient was 21 years in average( range from 18 to 23 years ). All were males and soldiers. The evaluation was made by comparison of MRI and plain radiograph, and duration of symptom was evaluated with MRI grading by Fredericson et al.
RESULT
The locations of stress fracture of long bones were tibia(n=25), fibula(n=14), and femur(n=6). MRI findings were bone marrow edema in 38(84.4%)cases, intramedullary low signal intensity band in 19(42.2%)cases which was continuous with cortex and cortical fracture line. Periosteal reaction was seen in 45(100%)cases and surrounding soft tissue edema in 20(44.4%)cases. Plain X-ray findings were peristeal reaction in 31( 68.9%)cases, medullary sclerosis in 10(22.2%)cases, and cortical fracture line in 8(17.8%) cases. Duration of symptom was longer in higher MRI grade.
CONCLUSION
MRI was more useful in early diagnosis and differential diagnosis of stress fracture, showing various findings than plain radiograph. MRI grading was helpful in planning tlhe therapy of stress fracture.

AMRI Study of Associated Soft Tissue Injury in Tibial Plateau Fractures: Jang Suk Choi, Young Chang Kim, Sung Suk Seo, Ki Chan Ahn, Chang Sub Lee, Jae Sang Choi; J Korean Soc Fract 2000;13(3):501-506. Published online July 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.3.501

Abstract PDF: Tibial plateau fractures can occur concomitent with injuries to the collateral, cruciate ligament and mensci. The purpose of this article is to demonstrate the frequency of soft tissue injuries associated with tibial plateau fractures and analyze the pattern of fracture more accurately by magnetic resonance imaging(MRI). Thirty one plateau fractures were evaluated in this study. MRI was more accurate in determining the classification of the fracture and measuring the displacement and depression of fragment. There was a 71%(22 of 31) frequency of associated soft tissue injuries in this series of tibial plateau fractures. The medial collateral ligaments were injured in 32.3%(10 of 31), the anterior cruciate ligaments in 29%(9 of 31), the posterior cruciated ligament in 22.5%(7 of 31), the lateral collateral ligament in 19.4%(6 of 31), and the menisci in 39%(12of 31). Schatzker type II and IV fracture patterns were associated with the highest frequency of soft tissure injuries. Medial collateral ligament injuries were most commonly associated with Schatzker type II fracture patterns. Menisci were most commonly injured with Schazker type IV fracture patterns. Most of the patients with acute tibial plateau fracture were commonly associated with ligamentous and meniscal injuries. MRI can aid in accurate evaluation of tibial plateau fracture patterns and decision of treatement plan.

Clinical and Radiologic Analysis of Occult Osseous Lesion on Magnetic Resonance Imaging in Acute Knee Injury: Seung Key Kim, Jong Hun Lee, Nam Gee Lee, Chang Beom Park, Han Chang; J Korean Soc Fract 1997;10(4):843-850. Published online October 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.4.843

Abstract PDF: Bone bruise or occult osseous lesion on magnetic resonance imaging was focused on the indirect sign of acute anterior cruciate ligament injury. But there were few reports which compared the location of bone bruise with the injured structure. The purposes of this study were to identify the common pattern of location of bone bruise, and to analyze the relationship between the location and injured structure or mechanism of injury. The authors reviewed 76 magnetic resonance imaging studies of the knee from March 1993 to May 1994 which show the sign of bone bruise in acute knee injury within six weeks. The mean age of the patient was 26.3 years and the main cause of injury was traffic accident. The final diagnosis was 20 cases of isolated medial collateral ligament injury, 17 cases of isolated anterior cruciate ligament injury, 16 cases of combined anterior cruciate and medial collateral ligament injury, 7 cases of meniscus injury, 6 cases of combined posterior cruciate and medial collateral ligament injury, 5 cases of isolated posterior cruciate ligament injury, 2 cases of patella dislocation, 1 case of lateral collateral ligment injury, and 2 cases of undiagnosed knee injury. In isolated MCL injuries, bone bruises were all confined to the lateral compartment. In isolated injury of ACL, the most common pattern of location of bone bruises were lateral tibial plateau and lateral femoral condyle(47.1%). In combined ACL and MCL injury, the most common pattern of location was lateral tibial plateau, only(43.8%). Bone bruise on MRI may be easy to detect during interpretation and we can obtain much information to decide the diagnosis and prognosis.
