OBJECTIVES: To evaluate the clinical significance of vertebral bone bruise (VBB) in terms of subsequent collapse after osteoporotic thoracolumbar vertebral fractures. METHODS: We reviewed 41 consecutive patients with 46 osteoporotic thoracolumbar vertebral fractures treated nonoperatively from March 2007 to February 2010. Anterior wedge angle (AWA) was measured on plain radiographs and the change of AWA between the initial and last measurement was used to represent the subsequent vertebral collapse. The size of VBB was measured and VBB ratio was calculated on T1-weighted sagittal MR image. RESULTS: The average VBB ratio was 49.1% and the average change of AWA was 7.1degrees. Only VBB ratio significantly correlated with the change of AWA (P<0.001, cc=0.660). The other factors such as age, initial AWA, and endplate status showed no significant correlation with the change of AWA (P=0.629, P=0.724, P=0.690, respectively). In DEXA group, no correlation was found between T-score and the change of AWA as well as between T-score and VBB ratio (P=0.548, P=0.370, respectively). Five fractures were diagnosed as delayed post-traumatic vertebral collapse. Their average VBB ratio was 71.2% which was significantly higher than that of the other subjects (P=0.015). The fractures with VBB ratio more than 60% was likely to progress to delayed post-traumatic vertebral collapse. CONCLUSIONS: VBB after osteoporotic thoracolumbar vertebral fracture was significantly correlated with subsequent vertebral collapse (cc=0.660). We recommend the patients with a large vertebral bone bruise, especially more than 60%, should be followed up meticulously for the early detection of delayed post-traumatic vertebral collapse.

At Ha Noi, Dong Da Hospital from June 1999 to September 2002, 17 patients aged 15-60 years old (13 males, 4 females) were diagnosed injured chronical peripediculitis by clinical signs and dental X ray local image. Contusion causes occured with higher rate, 13/17 patients (76.5%) have had occlusion conlusion, mainly in 15-24 years old range 10/17 patients (58.8%). Contusion causes injury mainly occured in incisirus teeth 13/17 patients (76.5%). After 3 months treatment in 2/17 patients (11.8%) injured lesions were healed.

Recent advances in diagnosis and therapy for head injury have brought some changes in concepts, definition of the terms, therapeutic methods and the duration of treatment. In medical certificates, the diagnosis and duration of treatment also need to be changed according to the new concepts. Mixed use of the terms according to the classic and the new concepts may cause confusion. We investigated with a questionnaire to assess the acceptability of the new concepts of head injury, and seeked for a plan to avoid possible confusion in medical certificates. We sent questionnaires for diagnosis and duration of treatment of 10 given examples of head injury to 367 neurosurgeons whose addresses could be identified. Questionnaires were answered by 52 neurosurgeons. The diagnosis described in the questionnaires showed wide variability with a range of 10 to 32 different descriptions, on average 16.8 different descriptions for each case. Duration of treatment also revealed great discrepancy. Coefficients of variation for duration of treatment varied from 33.44% to 54.37%. Cerebral contusion was the most commonly used term. It was described in every 10 given examples, and to take an average, 32.3 neurosurgeons used cerebral contusion or each case. To avoid possible confusion in medical certificates, it is necessary to make a guide for medical certificates for head injuries according to the new concepts, and a chance of training of this guide should be provided.

Injury is generally defined as morphological changes due to physical or chemical stress, inflammatory or repair process, or secondary events of the other disease. In the nontraumatic injuries of the lung, direct physical effects to the lung such as contusion or rupture of the lung must be excluded. So, the types of nontraumatic injuries of lung are all pathologic changes of lung except for congenital anomalies; infectious of inflammatory disease, aspiration induced injuries, environmental or occupational lung disease, postoperative pulmonary changes, poison or drug induced toxic injuries, radiation injury, etc...

The use of ultrasound for evaluation of blunt testicular injury allows contusion to be differentiated from rupture, and some authors advocate reserving surgical management for testicular rupture. We reviewed 22 operated cases of blunt scrotal trauma, 10 cases of them were evaluated with ultrasound preoperatively. In 8 of 10 cases, the tunica albuginea rupture was correctly diagnosed by ultrasonography but there were one false-positive and one false-negative diagnosis of rupture. Without preoperative ultrasound diagnosis, 12 cases were explorated because of suspicious testicular rupture only by physical examination. Three cases of them had intact tunica albuginea. These results suggest that the ultrasound diagnosis of blunt scrotal trauma is not sufficiently accurate to eliminate is highly sccurate, readily available.

The clinical observations were made on 66 patients of renal injuries during the period from 1985 to 1991) The results were as follows: I. The renal injuries were classified as contusion, laceration, rupture, pedicle injury according to Cass and Luxenberg`s classification. The patient numbers of each group were 42 (63.6%), 11 (16.3%).11 (16.3%) and 2 (3%). 2. The sonography was useful by complementary diagnostic tool of excretory urography in major renal injuries. 3. The computerized tomography was useful in diagnosing combined injuries and detecting injuries which were not detected in excretory pyelography. 4. The treatment of many. major renal injuries could be done conservatively with detailed and accurate diagnosis using computerized tomography.

The effect of naloxone on blood flow was studied in cats subjected to 400 gm-cm contusion injuries of the thoracic spinal cord. Ten cats were treated with 10 mg/kg naloxone 45 to 60 minutes after injury. Ten cats were given 10 mL of saline instead of naloxone, and 10 cats were neither injured nor treated. Hydrogen clearance was used to measure blood flow in the lateral white column at the contusion site. Naloxone, given intravenously, significantly improved the blood flow rates in the lateral column white matter. At 2 hours after injury, the mean blood flow in the saline-treated cats fell to 6.01+/-0.90 mL/100 gm/min, whereas it increased 8.47+/-1.14 mL/100gm/min in naloxone-treated cats (p<0.05). The authors conclude that naloxone may be useful for spinal cord injury.

PURPOSE: To evaluate the characteristic MR findings in injury of the anterior cruciate ligament (ACL) with associated bony lesions. MATERIALS AND METHODS: We reviewed MR findings and the corresponding arthroscopic or operative results of 48 patients with ACL injuries, and evaluated ACL signal intensity and contour. In associated bony lesions, we determined the location of avulsion fracture and bony bruise. RESULTS: Cmplete ACL tears were seen in 27 cases, partial tears in 13, and avulsion injury in eight. Complete tears showed heterogeneously increased signal intensity with contour bulging in ten cases (37 %), and combined bony lesion in 14 (52 %). ACL with a thin continous low signal intensity band surrounding heterogeneously-increased signal intensity suggested partial tears, and was seen in three of 13 proven cases (23 %) of partial ACL tears ; combined bony lesion was seen in four such cases (31 %). There were eight cases of avulsion fracture ; the most frequent site was the anterolateral portion of the tibial spine (n=6). The most frequent sites of bony lesion were at the midportion of the lateral femoral condyle (n=6), and the posterior portion of the lateral tibial plateau (n=6) ; the next most frequent site was the anterior portion of the lateral tibial plateau (n=5). CONCLUSION: Tearing of the ACL was seen on MRI as ligament discontinuity, and heterogeneously increased signal intensity with ACL contour bulging. The most frequent sites of associated bony lesions were the midportion of the lateral femoral condyle, and the posterior portion of the lateral tibial plateau. In associated bony lesions, bony contusion suggested ACL tearing, but avulsion fracture suggested ligament avulsion injury without tear.
