A 5-day-old male Korean native calf was referred with the primary complaint of anorexia, absence of feces, depression, and abdominal distention. Although this case was tentatively diagnosed as atresia coli, plain and contrast radiography was performed to confirm site and appearance of obstruction. A plain radiograph revealed gas distension in the large intestine, with absence of fecal material in the descending colon. In a contrast radiograph, the blind part of descending colon that was accumulated with contrast media smoothly protruded to distended colon with gas and the middle part was seen as narrow. These findings were well corresponded with the mucosal blockage junction between distended spiral loop with gas and descending colon that was hypoplasia or atropy in necropsy. In conclusion, contrast radiography was considered very useful method to identify the site and type of obstruction in diagnosis of atresia coli.

A 46-year-old female presented a mass on her right lower leg where she had a burn injury due to moxibustion 10 years ago. Physical examination revealed a 3 cm sized firm nodule with tenderness. Plain radiograph was performed and it revealed well-defined calcifications. According to the history of moxibustion burn injury and the result of plain radiograph, dystrophic calcinosis cutis caused by burn injury was suspected. The patient underwent excisional biopsy using pre-,intra-, and post-operative ultrasonography (USG). There was no sign of recurrence. Herein, we report a case of a 46-year-old healthy woman who presented with single hard nodule on the right lower leg. Our case is worthwhile in two respects. First, It is first case report of dystrophic calcinosis cutis due to moxibustion burn injury. In east asian culture, moxibustion is a commonly conducted procedure and it often induces burn injury. Second, USG was used pre-, intra-, and post-operatively to assess the shape, location, and depth of the calcinosis cutis and to determine the surgical margin.

Foreign body (FB) impaction in the maxillofacial area could be caused by knives, glass fragments, and vegetative materials. We present the rare case of a 62-year-old man with a large glass FB in the left cheek retained for over 40 years. He had traffic accident over 40 years ago and glass fragments impacted on his left cheek. Glass fragments were retained around the zygomatic arch with dimpled scar and unclear serous discharge, but other facial motor or sensory dysfunction was not observed. We confirmed three glass fragments with radiologic examination including plain radiograph and computed tomographic image. Under general anesthesia, impacted glass fragments were removed through the direct incision on the dimpled scar and the additional incision on the left lateral canthal area. Remnant FBs were not seen on an intraoperative C-arm radiograph. After 2 days of irrigation for inflammation control, the dimpled wound was sutured. The wound was healed without major complication and the original dimpled scar was much improved.

Objective : Oblique lumbar interbody fusion (OLIF) is a surgical technique that utilizes a large interbody cage to indirectly decompress neural elements. The position of the cage relative to the vertebral body could affect the degree of foraminal decompression. Previous studies determined the position of the cage using plain radiographs, with conflicting results regarding the influence of the position of the cage to the degree of neural foramen decompression. Because of the cage obliquity, computed tomography (CT) has better accuracy than plain radiograph for the measurement of the obliquely inserted cage. The objective of this study is to find the correlation between the position of the OLIF cage with the degree of indirect decompression of foraminal stenosis using CT and magnetic resonance imaging (MRI). Methods : We review imaging of 46 patients who underwent OLIF from L2-L5 for 68 levels. Segmental lordosis (SL) was measured in a plain radiograph. The positions of the cage were measured in CT. Spinal canal cross-sectional area (SCSA), and foraminal crosssectional area (FSCA) measurements using MRI were taken into consideration. Results : Patients' mean age was 69.7 years. SL increases 3.0±5.1 degrees. Significant increases in SCSA (33.3%), FCSA (43.7% on the left and 45.0% on the right foramen) were found (p<0.001). Multiple linear regression analysis shows putting the cage in the more posterior position correlated with more increase of FSCA and decreases SL correction. The position of the cage does not affect the degree of the central spinal canal decompression. Obliquity of the cage does not result in different degrees of foraminal decompression between right and left side neural foramen. Conclusion : Cage position near the posterior part of the vertebral body increases the decompression effect of the neural foramen while putting the cage in the more anterior position correlated with increases SL.

Background: The purpose of our study was to evaluate the accuracy of reduction based on postoperative computed tomography (CT) images after arthroscopic stabilization using tightrope system for unstable distal clavicle fracture. Methods: Twelve patients with distal clavicle fracture combined with coracoclavicular (CC) ligament injury (type II, V) who received arthroscopically assisted fixation using a flip button device were evaluated for accuracy of reduction using 3-dimensional postoperative CT scan by measuring the degree of distal clavicular angulation and clavicular shortening. Results: Immediate postoperative plain radiograph confirmed restoration of the CC distance (CCD) in 10 patients. At final follow-up, the CCD remained reduced anatomically on plain radiographs in these patients. All patients showed excessive posterior angulation and shortening compared to the opposite side. The average Constant score recovered to 94.8 at final follow-up. Conclusions: Indirect reduction and arthroscopic subacromial approach with flip button fixation of unstable distal clavicle fractures demonstrated favorable clinical results despite unavoidable posterior angulation of distal clavicle and shortening the total length of clavicle.

Purpose: To investigate the effect of heel elevation on the radiographic parameters of the forefoot. Materials and Methods: Forty feet in twenty-one adults were studied. Weight bearing dorsoplantar radiograph was taken with the foot on a flat surface and with the heel of the foot elevated by 5cm. Various parameters were measured and compared between the results with and without heel elevation. Result: The hallux valgus angle was increased by $5.0{\pm}3.5$ degrees with heel elevation and the change was statistically significant(p<0.01). There was no statistically significant changes in the other parameters. Conclusion: The results of this study suggest that high-heeled shoes might contribute in causing or aggravating the degrees of the hallux valgus.

A 73-year-old man with sudden sensory neural hearing loss received a stellate ganglion block. Two hours after the block, the patient complained of newly developed neck discomfort. After an additional two hours, the neck swelled up gradually and neck pain and dyspnea developed. A plain radiograph of neck revealed narrowing of the upper airway; a tracheostomy was performed and the dyspnea was improved. On the next day, the pain site extended to the right scapula and a CT image revealed a huge retropharyngeal hematoma. Hematoma evacuation and bleeder ligation were then performed and the patient was discharged on the fourth day after admission without any complications. A practitioner should always remember to educate the patients about possible complications and undertake intensive observation when performing procedures, even in patients who do not initially present with a compromised airway.

Chronic functional constipation is a common problem in childhood, with soiling a significant issue. It presents a management problem for pediatrician, and parental concern is high. About 5% of pediatric patients is known to have constipation and/or encopresis which is the second most referred disease in pediatric gastroenterology clinic, accounting for up to 25% of all visits. The etiology of constipation was based on initiation factors including vicious cycle concept, genetic factors, psychological factors, dietary influences and histologic abnormalities of colon. Emphasis is placed on the evaluation and management options that are available to the treating pediatrician. Careful history taking is most important to diagnose functional constipation. In addition, diagnostic tests such as plain abdominal radiograph, colonic transit study, anorectal manometry, barium enema were helpful to diagnose the constipation. Childhood constipation can be very delicate to treat. It often requires prolonged supports by physicians and parents, demystification, medical treatment and especially with the child and parent's cooperation.

Vertebral artery loop formation causing encroachment on cervical neural foramen and canal is a rare cause of cervical radiculopathy. We report a case of 61-year-old woman with vertebral artery loop formation who presented with right shoulder pain radiating to her arm for 2 years. Plain radiograph and computed tomography scan revealed widening of the right intervertebral foramen at the C5-6 level. Magnetic resonance imaging and angiogram confirmed the vertebral artery loop formation compressing the right C6 nerve root. We had considered microdecompressive surgery, but the patient's symptoms resolved after conservative management. Clinician should keep in mind that vertebral artery loop formation is one of important causes of cervical radiculopathy. Vertebral artery should be visualized using magnetic resonance angiography in suspected case.
