The mandibular condyle fracture occurs at 15-30% frequency of whole mandibular fracture. The treatment of choice is open reduction or closed reduction. In many cases, closed reduction is preferred for treatment of condylar fracture because it is hard to approach to condyle and there is risk of surgical complications, such as nerve damage in open reduction. Open reduction, however, has some advantages like possibility of anatomical reduction, occlusal stability and rapid functional recovery. Furthermore, it is possible to retain original ramal heights and to decrease deviation during mouth opening. There are many surgical approaches for open reduction of subcondyle fracture. At present, transoral approach using trochar device is tried for effective and minimally invasive method for open reduction of subcondyle fracture. And the authors report the cases of reduction of subcondyle fracture with transoral approach using trochar device.

Purpose: Open pelvic bone fractures are relatively rare and are considered more severe than closed fractures. This study aimed to compare the clinical outcomes of open and closed severe pelvic bone fractures. Methods: Patients with severe pelvic bone fractures (pelvic Abbreviated Injury Scale score, ≥4) admitted at a single level I trauma center between 2016 and 2020 were retrospectively analyzed. Patients aged <16 years and those with incomplete medical records were excluded from the study. The patients were divided into open and closed fracture groups, and their demographics, treatment, and clinical outcomes were compared before and after 1:2 propensity score matching. Results: Of the 321 patients, 24 were in the open fracture group and 297 were in the closed fracture group. The open fracture group had more infections (37.5% vs. 5.7%, P<0.001) and longer stays in the intensive care unit (median 11 days, interquartile range [IQR] 6-30 days vs. median 5 days, IQR 2-13 days; P=0.005), but mortality did not show a statistically significant difference (20.8% vs. 15.5%, P=0.559) before matching. After 1:2 propensity score matching, the infection rate was significantly higher in the open fracture group (37.5% vs. 6.3%, P=0.002), whereas the length of intensive care unit stay (median 11 days, IQR 6-30 days vs. median 8 days, IQR 4-19 days; P=0.312) and mortality (20.8% vs. 27.1%, P=0.564) were not significantly different. Conclusions: The open pelvic fracture group had more infections than the closed pelvic fracture group, but mortality was not significantly different. Aggressive treatment of pelvic bone fractures is important regardless of the fracture type, and efforts to reduce infection are important in open pelvic bone fractures.

Purpose: The management of fractures of mandibular subcondyle continues to be controversial between open and closed treatment. The purpose of this article is to explain the endoscopic assisted open reduction and internal fixation and minimize the controversy. Methods: Nine patients of mandibular subcondylar fracture were reduced and fixed by using intraoral endoscopic - assisted open reduction and internal fixation and were followed up for 14 ~ 24 months after surgery. Results: Eight patients of mandibular subcondylar fracture had been treated without significant complications. One patient, whose malocclusion had been remained, was recovered normal occlusion by maxillomandibular fixation using intermaxillary screws for 3 weeks. Conclusion: The advantages of endoscopic - assisted open reduction and internal fixation are direct visualization, accurate fracture repair, minimized scar, decreased morbidity. And maxillomandibular fixation is not needed when it is done by accurate reduction and rigid fixation with one miniplate in the region of subcondylar fracture. With the above consideration, endoscopic - assisted open reduction and internal fixation can be considered as one of the best treament for subcondylar fracture of the mandible.

A 6-month-old, weighing 2.8 kg, female, domestic short-haired cat presented with open fracture at right distal radius about a month ago. Based on radiological findings, hyperplasia at the right radioulna and left humerus was found. Results of the cytological examination were inflammatory reaction and reactive osteoblast. Distal radial ostectomy proceeded with necrotic bone debridement. Three weeks after operation, the radial bone lysis was seen on radiograph but clinical condition improved. Hyperplasia at the right radioulna and left humerus was dissolved. Two months after operation, she can use her both forelimbs despite right elbow have been diagnosed as arthrosclerosis because of periosteal reaction. Six months after operation, clinical symptoms of limbs were not detected. In this case, open fracture was treated through delayed surgical debridement procedure, therefore hematogenous osteomyelitis occurs at another forelimb. The longer a wound remains open, the more likely it is that infection will develop. The infection can occur to fracture bone and seed from hematogenous spread to another normal bone. In conclusion, when open fracture occurs, early antibiotic treatment and urgent surgical intervention are recommended.

Objectives: Selection of treatment methods for mandibular condylar fractures remains controversial. In this study, we investigated treatment methods for condylar fractures to determine the indications for open or closed reduction. Patients and Methods: Patients >12 years of age treated for mandibular condylar fractures with a follow-up period of ≥3 months were included in this study. The medical records of enrolled patients were reviewed for sex, age, fracture site, treatment method (open or closed reconstruction), postoperative intermaxillary fixation period, operation time, and complications. Radiological analysis of fracture fragment displacement and changes in ramal height difference was performed using computed tomography and panoramic radiography. Results: A total of 198 patients was investigated, 48.0% (n=95) of whom underwent closed reduction and 52.0% (n=103) underwent open reduction. There was no significant correlation between reduction method and patient sex, age, or follow-up period. No statistically significant difference between the incidence of complications and treatment method was observed. None of the patients underwent open reduction of condylar head fracture. Binary logistic regression analysis showed that open reduction was significantly more frequent in patients with subcondylar fracture compared to in those with a fracture in the condylar head area. There was no statistically significant correlation between the groups and fracture fragment displacement. However, there was a significant difference between the treatment groups in amount of change in ramal height difference between the fractured and the non-fractured sides during treatment. Conclusion: No significant clinical differences were found between the open and closed reduction methods in patients with mandibular condylar fractures. According to fracture site, closed reduction was preferred for condyle head fractures. There was no significant relationship between fracture fragment displacement and treatment method.

Background: The purpose of this study is to compare the radiological and clinical outcomes after open reduction and plate fixation of midshaft clavicle fractures between patients who achieved successful anatomical reduction and those who had a remaining fracture gap even after open reduction and plate fixation, and were thus treated with additional demineralized bone matrix (DBM). Methods: This retrospective analysis was conducted on 56 consecutive patients who underwent open reduction and internal fixation using a locking compression plate for acute displaced midshaft clavicle fractures, and who underwent radiographic and clinical outcome evaluations at least 6 months postoperatively. The outcomes between those who achieved perfect anatomical reduction without remnant gap (n=32) and those who had a remaining fracture gap even after open reduction and plate fixation treated with additional DBM (n=24) were evaluated. Results: There were no differences in the use of lag screws or wiring and operation time (all p>0.05) between those with and without remnant gap. No difference in the average radiological union time and clinical outcomes (satisfaction and Constant score) was observed between the two groups (all p>0.05). However, significantly faster union time was observed for AO type A fracture compared with other types (p=0.012), and traffic accident showed association with worse clinical outcomes compared with other causes of injury. Conclusions: Surgical outcome of midshaft clavicle fracture was more affected by initial fracture type and event, and re-reduction and re-fixation of the fracture to obtain a perfect anatomical reduction spending time appears to be unnecessary if rigid fixation is achieved.

Purpose: to determine the results after open intramedullary nailing and tension band suture technique in proximal humerus fracture for improving the stability and decreasing the complications. Materials and Method: Authors reviewed 27 patients treated by open intramedullary nailing and tension band suture technique. Mean follow-up period was 39 months (24-59months). Surgical neck fracture were 6 cases, surgical neck fracture with shaft fracture were 3 cases, three part fracture with greater tuberosity fracture were 17 cases, four part fracture was 1 case and fracture and dislocation were 2 cases Results: We got the bony union in 26 cases. Average pain scale was 1 point (0-6), Neer score was 86 point(45-99) and ASES score was 85 point(40-100). We separate all cases in two groups based on age (65 years), L-spine t-score (-2.5) and Neer classification (2 and 3 part). There is no significance in pain scale, Neer score and ASES score between each group. Conclusion: As a method of surgical treatment on severe proximal humeral fractures, we recommend intramedullary nailing and tension band suture technique and it may have particular advantages in early exercise and satisfactory functional outcome.

Purpose: The aim of this study was to evaluate the complications of open reduction and internal fixation of mandibular fracture with miniplates. Patients and Methods: A total of 134 patients who presented with 196 fractures were analyzed retrospectively. Complications were evaluated for factors such as age, the site of fracture, the severity of fracture, delayed operation, preoperative wound contamination, the site and disposition of teeth in the fracture line and midfacial fractures. Statistical analysis was used to compare complications to risk factors. Results: Of the 134 patients, 20 patients had some form of postoperative complications and complication rate was 14.9%. These complications included infection, plate fracture, malocclusion, wound dehiscence, nerve injury and nonunion. There was a significant correlation between complication rate and the severity of fracture, preoperative wound contamination and the site of the fracture and disposition of teeth(p<0.05). Conclusion: The occurrence of postoperative complications in the treatment of mandibular fractures was related to the severity of fracture, preoperative wound contamination and the site of the fracture and disposition of teeth.

An ankle sprain is a relatively common sports-related injury but a severe open ankle sprain (SOAS) is very rare. A 27-year-old female athlete was injured during running and was hospitalized because of an inversed ankle injury with an open wound. She was diagnosed initially with an open-avulsion fracture at the tip of the fibula with an anterior talofibular ligament tear. The patient was finally diagnosed with SOAS from the surgical findings and literature review. SOAS should also be considered if there is a transverse open wound at the time of an ankle injury.
