Purpose: This paper reports the surgical treatment results of open calcaneal fractures performed at the author’s clinics focusing on open calcaneal fractures to help understand the appropriate treatment and realistic outcomes. Materials and Methods: This study was conducted on 22 cases out of 30 patients who visited the hospital from February 2009 to December 2019 and were followed up for more than one year. In open fractures, the fracture was classified using the Gustilo-Anderson classification and was evaluated using the soft tissue status at the time of visit. Intra-articular calcaneal fractures were classified using Sanders classification. The radiological parameters were measured for the Böhler angle, Gissane angle, calcaneal length, height, and width before and after surgery, and at the last follow-up. The clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and investigated complications. In addition, statistical analysis of the incidence and associated factors of posttraumatic arthritis was conducted. Results: In all cases, the surgical treatment was performed by minimally invasive surgery. The AOFAS ankle-hindfoot scale conducted for a clinical evaluation of the final follow-up was averaged 72.5 points. In the classification of open fractures, the Gustilo-Anderson classification type IIIA was the most common, and the Sanders type III was the most common. Of the 22 cases after surgery, 15 cases had complications, 11 cases had posttraumatic arthritis, eight cases had an infection, and 4 cases had both complications. Only the Sanders classification showed a statistically significant correlation with the incidence of posttraumatic osteoarthritis (p-value 0.032). Conclusion In treating open calcaneal fractures, internal fixation by a minimally invasive approach showed relatively satisfactory results. However, follow-up research will be needed, including the results of a long-term follow-up through a large number of cases and comparative studies with other surgical methods.

Purpose: Ankle sprains are among the most common musculoskeletal injuries, and many videos have been shared with patients through YouTube. YouTube allows the easy sharing of information, but there are accuracy and reliability issues due to the lack of verification processes for video producers. This study evaluated ankle sprain videos on YouTube and the correlation between the video scores and viewer preferences using “the number of likes and views”. Materials and Methods: For analysis, the words “ankle sprains”, “ankle exercise”, and “ankle rehabilitation” were searched on YouTube. Only videos taken in Korean were analyzed, and videos with less than 10,000 views and for commercial purposes were excluded. For 31 videos, two orthopedic surgeons and one orthopedic resident used one evaluation tool to evaluate the video quality with up to 30 points for subcategories. The scores between each evaluator were then averaged to evaluate the video quality. To reflect the viewer preferences, “the number of likes and views” were analyzed, and the relationship between the video score and “the number of likes and views” of the video was analyzed statistically. Results: The average score for the video was 9.33. The average scores for subcategories were anatomy and symptoms, 0.90; biomechanics and trauma-mechanism, 0.61; imaging quality, 0.95; clinical evaluation and physical examination, 0.61; treatment, 1.41; rehabilitation, 2.39; prevention and after effects, 0.89; and overall video quality, 1.61. The average of “the number of views” was 50,218.35 times, and “the number of likes” was 893.77 times. No correlation was observed between the video scores and “the number of likes and views”. Conclusion Most videos posted on YouTube did not provide high-quality medical information on ankle sprain, and there was no correlation between the video scores and viewer preferences. This suggests that incorrect medical information is being transmitted to patients, which can be harmful. Therefore, it is necessary to present the latest trend treatment and rehabilitation protocols for ankle sprains in an expert council and promote it through various channels.

Primary malignant lymphoma of the urinary bladder is a rare disease, and it accounts for only 0.2% of all the cases of extranodal lymphoma. The prognosis of primary bladder lymphoma has been favorable, with many patients being alive and well several years after treatment. We report here on a case of primary diffuse large B cell lymphoma of the urinary bladder in a 75-year-old man patient who presented with a one-month history of persistent dysuria. The abdominal CT revealed a mass at the posterior wall of the urinary bladder. The tissue obtained by transurethral cystoscopy showed an atypical lymphoid proliferation, which was consistent with diffuse large B cell lymphoma. The patient received systemic chemotherapy of rituximab and CHOP (cyclophosphamide, doxorubicin, vincristine and prednisolone) and he achieved a significant partial remission.
