Background: Conventionally ankle fractures have been classified using plain radiographs. Because of complex 3-dimensional anatomy and complexity of injuries, plain radiographs may not always be able to clearly depict the complete fracture pattern. There is a paucity of studies regarding the utility of computed tomography (CT) scanning in malleolar ankle fractures (MAFs). Hence, we conducted this study to further understand the role of the CT scan in MAFs. Methods: A prospective study of 56 consecutive malleolar ankle fractures was conducted. In the first evaluation by a team of 3 observers, a management plan was made based on plain radiographs. All patients received a CT scan evaluation with a standard protocol. The second evaluation by the same team included formulating an operative plan based on the CT. Results: In 13 (23.2%) cases, the management plan changed after CT evaluation. In most of the cases, the change in the management plan included an alteration in fixation of the posterior malleolus followed by lateral malleolus in 4 cases. Most of the changes took place in AO 44 type C followed by types B and A. Maximum change was noted in trimalleolar fractures followed by bimalleolar and unimalleolar. The most common morphological characteristic fracture identified on CT scan that was not evident on plain radiography was Chaput fracture in 17 cases. Conclusion: CT scan evaluation of MAFs changed the management plan in a significant number of cases, especially if the fractured fragment included a posterior malleolus, AO type C, and/or if 2 or more malleoli were fractured as noted on plain x rays. Level of Evidence: Level IV, case series.

Background: This paper endeavors to identify an expedient approach for the detection of the brain tumor in MRI images. The detection of tumor is based on i) review of the machine learning approach for the identification of brain tumor and ii) review of a suitable approach for brain tumor detection. Discussion: This review focuses on different imaging techniques such as X-rays, PET, CT- Scan, and MRI. This survey identifies a different approach with better accuracy for tumor detection. This further includes the image processing method. In most applications, machine learning shows better performance than manual segmentation of the brain tumors from MRI images as it is a difficult and time-consuming task. For fast and better computational results, radiology used a different approach with MRI, CT-scan, X-ray, and PET. Furthermore, summarizing the literature, this paper also provides a critical evaluation of the surveyed literature which reveals new facets of research. Conclusion: The problem faced by the researchers during brain tumor detection techniques and machine learning applications for clinical settings have also been discussed.

ABSTRAKPenyakit Osteochondral Lesion of the Talus (OLT) adalah kelainan pada tulang talus di lapisan subchondral yang berupa lesi osteochondral pada talar dome dengan konsekuensi abnormalitas pada tulang rawan sendi talar. Pasien biasanya datang berobat ke tenaga kesehatan dengan keluhan yang tidak spesifik dan dengan gejala seperti nyeri pada pergelangan kaki, bengkak serta berkurangnya berkurangnya ruang gerak. Penegakan diagnosis bisa dilakukan dengan anamnesis, pemeriksaan fisik dan pemeriksaan penunjang sederhana seperti foto X-ray maupun pemeriksaan penunjang canggih seperti CT-Scan dan MRI. Tatalaksana OLT bervariasi. Tatalaksana pada OLT tergantung dari tahapan lesi, kronisitasnya, dan keluhan simtomatis yang menyertainya. Pasien dengan keluhan simtomatis yang akut dan non-displaced sering diberikan terapi nonoperatif biasanya berupa terapi konservatif dengan imobilisasi. Lesi yang tidak berhasil atau tidak menunjukkan perbaikan dalam keluhan simtomatisnya setelah 3 sampai 6 bulan, serta lesi dengan displacement dapat direncanakan untuk terapi operatif. Ada beberapa macam tehnik operatif yang dapat dilakukan untuk menyembuhkan OLT. Tehnik operatif ini dapat dikategorikan menjadi cartilage repair, cartilage regeneration dan cartilage replacement techniques.Kata kunci: osteochondral lesion of the talus, patofisiologi, tatalaksanaABSTRACTOsteochondral Lesion of the Talus (OLT) is an abnormality in the talus bone in the subchondral layer in the form of osteochondral lesions in the talar dome with consequent abnormalities in the talar joint cartilage. Patients usually come to a health care provider with nonspecific complaints and with symptoms such as pain in the ankles, swelling and reduced space for movement. The diagnosis can be made with a history, physical examination and simple investigations such as X-rays and sophisticated investigations such as CT-Scan and MRI. The management of OLT varies. The management of OLT depends on the stage of the lesion, its chronicity, and the accompanying symptomatic complaints. Patients with acute and non-displaced symptomatic complaints are often given nonoperative therapy usually in the form of conservative therapy with immobilization. Lesions that are unsuccessful or show no improvement in symptomatic complaints after 3 to 6 months, and lesions with displacement can be planned for operative therapy. There are several types of operative techniques that can be done to cure OLT. These operative techniques can be categorized into cartilage repair, cartilage regeneration and cartilage replacement techniques. Keywords: osteochondral lesion of the talus, patophysiology, treatment

Spinal Compression Fracture

A burst fracture is a descriptive term for an injury to the spine in which the vertebral body is severely compressed. They typically occur from severe trauma, such as a motor vehicle accident or a fall from a height. With a great deal of force vertically onto the spine, a vertebra may be crushed .If it is only crushed in the front part of the spine, it becomes wedge shaped and is called a compression fracture. However, if the vertebral body is crushed in all directions it is called a burst fracture. Burst fractures cause severe pain. The diagnosis of a burst fracture is usually made by x-rays and a CT scan. Occasionally, an MRI scan may be ordered as well, in order to assess the amount of soft tissue trauma, bleeding or ligament disruption. The review of the CT scan and x-rays allows the treating physician to make a determination as to the level of the fracture, whether it is a compression fracture, burst fracture or fracture dislocation. A spinal compression fracture also may be caused by trauma to the spine. Events that may cause trauma to the spine can include: A car accident, a hard fall or a fall from a height of more than 15 feet, landing on the feet, and a blow to the head. Any fall from a standing height that results in a spinal compression fracture or any other fracture most likely indicates weak bones due to osteoporosis. The physical exam should be performed to document both spinal deformity, that is, angulation of the spine or tenderness of the spine at the level of fracture, as well as, a neurologic exam. Neurologic exam should include testing of the muscle strength, sensation, and reflexes of the lower extremities, as well as, testing of bowel and bladder sphincter control. A 36 year old man was brought to the hospital as he had a fall from electric pole approximately 20 feet height. He had sustaining injury to the neck. Surgery was done as patient was diagnosed with C6 burst fracture with fracture dislocation of C5-C7. Therapeutic Interventions includes exercises, strengthening exercises, cervical fracture fixation, and traction.

Category: Other Introduction/Purpose: Foot and ankle surgeons routinely prescribe diagnostic imaging that exposes patients to potentially harmful ionizing radiation. The purpose of this study is to characterize patients’ knowledge regarding radiation exposure associated with common forms of foot and ankle imaging. Methods: A survey was administered to all new patients prior to their first foot and ankle clinic appointments. Patients were asked to compare the amount of harmful radiation associated with chest x-rays to that associated with various types of foot and ankle imaging. Results were tabulated and compared to actual values of radiation exposure from the published literature. Results: A total of 890 patients were invited to participate, of whom 791 (88.9%) completed the survey. The majority of patients believed that a foot x-ray, an ankle x-ray, a “low dose” CT scan of the foot and ankle (alluding to cone-beam CT), and a traditional CT scan of the foot and ankle all contain similar amounts of harmful ionizing radiation to a chest x-ray (Table 1). This is in contrast to the published literature, which suggests that foot x-rays, ankle x-rays, cone beam CT scans of the foot and ankle, and traditional CT scans of the foot and ankle expose patients to 0.006, 0.006, 0.127, and 0.833 chest x-rays worth of radiation. Conclusion: The results of the present study suggest that patients greatly over-estimate the amount of harmful ionizing radiation associated with plain film and cone-beam CT scans of the foot and ankle. Interestingly, their estimates of radiation associated with traditional CT scans of the foot and ankle were relatively accurate. Results suggest that patients may benefit from increased counseling by surgeons regarding the relatively low risk of radiation exposure associated with plain film and cone-beam CT imaging of the foot and ankle.

Pneumothorax after trauma can be a life threatening injury and its care requires expeditious and accurate diagnosis and possible intervention. We performed a prospective, single blinded study with convenience sampling at a Level I trauma center comparing thoracic ultrasound with chest X-ray and CT scan in the detection of traumatic pneumothorax. Trauma patients that received a thoracic ultrasound, chest X-ray, and chest CT scan were included in the study. The chest X-rays were read by a radiologist who was blinded to the thoracic ultrasound results. Then both were compared with CT scan results. One hundred and twenty-five patients had a thoracic ultrasound performed in the 24-month period. Forty-six patients were excluded from the study due to lack of either a chest X-ray or chest CT scan. Of the remaining 79 patients there were 22 positive pneumothorax found by CT and of those 18 (82%) were found on ultrasound and 7 (32%) were found on chest X-ray. The sensitivity of thoracic ultrasound was found to be 81.8 per cent and the specificity was found to be 100 per cent. The sensitivity of chest X-ray was found to be 31.8 per cent and again the specificity was found to be 100 per cent. The negative predictive value of thoracic ultrasound for pneumothorax was 0.934 and the negative predictive value for chest X-ray for pneumothorax was found to be 0.792. We advocate the use of chest ultrasound for detection of pneumothorax in trauma patients.

Scaphoid Fractures

INTRODUCTION Up to 40% of scaphoid fractures are missed at initial presentation as clinical examination and plain radiographs are poor at identifying scaphoid fractures immediately after the injury. Avoiding a delay in diagnosis is essential to prevent the risk of non-union and early wrist arthritis. We demonstrate the use of CT scanning for the early confirmation of a scaphoid fracture. PATIENTS AND METHODS We conducted a retrospective, chronological review of patients who attended an upper limb fracture clinic from January 2001 to October 2003 in a small district general hospital. We performed a CT scan on all ‘clinical scaphoid’ patients who had negative plain X-ray films. RESULTS Overall, 70% of patients had a CT scan within 1 week of injury and not from date of accident and emergency attendance; 83% of patients had a CT scan within 2 weeks of injury. Of 118 patients identified, 32% had positive findings and 22% of ‘clinical scaphoid’ patients had scaphoid fractures. The proportion of positive findings for an acute scaphoid fracture was 68%. Additional pathologies identified on CT were capitate, triquetral and radial fractures. CONCLUSIONS Our audit shows that it is practical to perform CT on suspicious scaphoid fractures in a small district general hospital. We identified an extremely high false-negative rate for plain X-rays and demonstrate that the appropriate use of CT at initial fracture clinic attendance with ‘clinical scaphoid’ leads to an earlier diagnosis and reduces the need for prolonged immobilisation and repeated clinical review.

Disease Treatment

Nowadays radiological devices are diagnostic tools that are very necessary in medical care. The type of image used for the purpose of diagnosing disease is produced from medical equipment such as X-rays, USG, CT scan, MRI, and PET. The benefits of radiology examinations are to diagnose disease, treatment, and means of communication between doctors and patients. However, radiation exposure can damage cells. Therefore, a doctor is required to socialize about radiological examination to public.
