The anterior maxillary sinus walls are the most frequently injured sites in midfacial fractures. The maxillary sinus is a difficult surgical site for reduction and fixation due to its narrow surgical field, and has a chance of developing sinusitis when sufficient treatment is not given. In this study, the methods developed by the authors for managing such are introduced. Two small openings were made on both sides of the fracture line, then a suture knot was tied instead of wiring for reduction and fixation. Then an absorbable mesh was applied on top of the fracture site, with a suture knot for additional fixation. This method was applied on an actual patient, and it was a convenient method despite the narrow surgical field that was provided. The authors believe that using suture knots to fixate fractured segments and absorbable mesh is relatively convenient and economically efficient when it comes to the reduction and fixation of the maxillary sinus wall fracture with several fragments.

Ankylosing spondylitis (AS) is a chronic inflammatory disease presenting progressive spinal stiffness and sacroiliitis. Cervical spine fracture combined with AS should be treated with operation, but it is closely related with increased rates of surgical site infection, which are associated with an elevated erythrocyte sedimentation rate and elevated C-reactive protein. We report a case of delayed postoperative infection appeared in cervical paravertebral space, which was masked by laboratory findings and clinical characteristics represented in this rheumatic disease. A 53-year-old man who had medical history of AS got operation after cervical spine fracture. During hospitalization, he experienced aching pain originating from left posterior neck to shoulder, which was revealed out to be delayed postoperative infection, diagnostically obscured by elevated values of inflammatory markers. This case emphasizes detailed evaluation considering symptoms and comorbidity of the patient should be performed to apply proper management.

To examine among patients with vertebral compression fracture the extent to which signal-to-noise ratio (SNR) and Apparent Diffusion Coefficient (ADC) values at the lumbar vertebral compression fracture site vary on diffusion-weighted MR images according to varying b values on the 1.5T MR device. Diffusion-weighted MR images of 30 patients with compression fracture due to chronic osteoporosis who underwent vertebral MRI from Jan. 2008 to Nov. 2009 were respectively obtained using a 1.5-T MR scanner with the b values increased from 400, 600, 800, 1,000 to $1,200\;s/mm^2$. For diffusion-weighted MR images with different b values, the signal-to-noise ratio (SNR) was assessed at three sites: the site of compression fracture of the lumbar vertebral body at L1 to L5, and both the upper and lower discs of the said fracture site, while for ADC map images with different b values, the SNR and ADC were respectively assessed at those three sites. As a quantitative analysis, diffusion-weighted MR images and ADC map images with b value of $400\;s/mm^2$ (the base b values) were respectively compared with the corresponding images with each different b value. As far as qualitative analysis is concerned, for both diffusion-weighted MR and ADC map images with b value of $400\;s/mm^2$, the extent to which signal intensity values obtained at the site of compression fracture of the lumbar vertebral body at L1 to L5 vary according to the increasing b values were examined. The quantitative analysis found that for both diffusion-weighted MR and ADC map images, as the b values increased, the SNR were relatively lowered at all the three sites, compared to the base b value. Also, it was found that as the b values increased, ADC valueswere relatively lowered at all the three sites on ADC map images. On the other hand, the qualitative analysis found that as the b values increased to more than $400\;s/mm^2$, the signal intensity gradually decreased at all the sites, while at the levels of more than $1,000\;s/mm^2$, severe image noises appeared at all of the three sites. In addition, higher signal intensity was found at the site of compression fracture of the lumbar vertebral body than at the discs. Findings showed that with the b value being increased, both the signal-to-noise ratio (SNR) and Apparent Diffusion Coefficient (ADC) values gradually decreased at all the sites of the lumbar vertebral compression fracture and both the upper and lower discs of the fracture site, suggesting that there is a possibility of a wider range of applications to assessment of various vertebral pathologies by utilizing multi b values in the diffusion-weighted MRI examination.

Objectives This study aimed to investigate the trend in treating fracture with acupuncture and to evaluate the quality of case reports. Methods All case reports of fractures treated with acupuncture were extracted from four Korean web databases. We classified these studies by five fracture sites and investigated frequently used meridian and acupoint, outcome measurements, treatment period. And we assessed the quality of the case reports by the STandards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) guidelines. Results A total of 33 case reports were included. The outcome measurements were divided into six categories, and the outcome measurements used in more than three studies showed improvement in patient symptoms. The mainly used meridians for each fracture site were as follows: chest and abdomen (GB, LR, CV), back (BL, GB), upper limb (LI, TE), lower Limb (GB, ST, BL, SP). The most commonly used acupoints for each fracture site were as follows: chest and abdomen (Ashi points, GB24, GB25, GB26, LR13, LR14, CV16, CV17, CV18, CV19), back (BL23, BL24, BL25, BL26, BL40, BL51, BL52, BL60, GB34), upper limb (LI4, LI10, LI11, TE3), lower limb (GB34, GB40). According to the STRICTA guidelines, more than 54.54% of the reports were found to be 'not reported' or 'not sufficient' in the following categories: 'response sought', 'description of participating acupuncturist', and 'number of needle insertions per subject per session'. Conclusions The meridians and acupuncture points frequently used for acupuncture treatment of fractures were near the fracture site. Future clinical studies involving acupuncture must be reported in accordance with the STRICTA guidelines to improve transparency and uniformity.

Purpose: It is relatively unusual that infraorbital rim fracture is accompanied by nasal bone fracture. In order to correct effectively, subciliary approach and intranasal manipulation are applied simultaneously. But if reduction is not successful, intranasal manipulation may become aggressive and this often causes complications. We introduce a method using intermaxillary fixation screws for decreasing such complications and effective reduction of fracture. Methods: Total seven patients with fracture of frontal process of maxilla were treated with this method. The fracture site was exposed through the subciliary approach, and one or two screws were inserted into the displaced fracture fragment. During the traction of the screws using the wire, the fracture fragment was pushed upward from the intranasal side using an elevator supplementarily and fixed with a plate and the screws. Results: In all patients, the fracture fragment was reduced successfully and no complication occurred during one year's postoperative follow-up. Conclusion: When reduction cannot be attained through a bone hook or an elevator alone, reduction of fracture fragment can be done easily using intermaxillary fixation screws. This method is less likely to cause a mucosal injury because intranasal manipulation is not aggressive. Furthermore, as the screw can be inserted and removed easily, this method is considered effective not only for fracture of frontal process of maxilla but also for fractures in other regions.

In the case of Ni/Au finished pad on the package side, the solder joint of SnAgCu system can bring brittle fracture under impact load such as drop test. Therefore, it's difficult to prevent the brittle fracture of lead-free solder, by controlling Cu content. The failure locus existing on the interface between $(Ni,Cu)_3Sn_4\;and\;(Cu,Ni)_6Sn_5$ IMC layers must be changed to other site in order to avoid brittle fracture due to impact load. It was not found any clear evidence that there were two IMC layers exist. But it was strongly assumed these were two layers which have different Cu-Ni composition. From the above analysis it was assumed that Cu atom in the solder alloy or substrate seemed to affect IMC composition and cause to IMC brittle fracture.

The hydraulic fracturing in a field site was performed for the measurement of in-situ stresses. For the estimation of the effect of a preexisting inclined fracture, the test on a preexisting fracture zone was also conducted. From the measurements at three shallow depths, the ratios of max. to min. horizontal stress showed the range of 1.19-1.56 and the K values showed the range of 2.62-3.86. In case of a preexisting fracture with the inclination of 15 degrees, the stresses calculated as upper bound values by considering it. It seemed from this that the inclination less than 15 degrees had small effect on the stress calculation.

The limit drawing ratio (LDR) is a major process parameter in the process design of deep drawing. If the actual drawing ratio is greater than the LDR for a particular stage, then an intermediate stage has to be added to the process sequence to avoid failure during the ratio. In this study, the optimal process design considering forming limit is performed for the first-drawing and redrawing by using finite element method combined with ductile fracture criterion. The LDR and the site of fracture initiation are predicted by means of the fracture criterion. From the results of finite element analysis, the optimal value of drawing ratio is obtained, which contributes to the more uniform distribution of thickness and the smaller values of the ductile fracture in final cup.
