Purpose: The purpose of this study is to investigate the incidence and patterns of fractures occurred in Inline skating accident. Materials and Method: We evaluated 20 patients, 20 cases(from september 2002 to August 2003) with fractures occurred during Inline skating. The incidence, sex, age, fracture site, associated injuries, causes of Inline skating injuries were analysed. The cases were male in 18(90$\%$), and female in 2(10$\%$). The most common distribution of age was in twenties and thirties. Result: The patients(12cases 60$\%$) with upper extremity fracture were more common than patients(8cases 40$\%$) with lower extremity fracture. Patients who had fracture in ankle were 35$\%$(7cases), forearm 20$\%$(4cases), wrist 20$\%$(4cases), elbow 15$\%$(3cases), thigh 5$\%$(1cases). According to the The Lauge-Hansen classification in ankle fractures there were four patients of supination-external rotation type, two patients of supination-abduction type, and 1 patient of pronation-external rotation type. In forearm and hand fractures, there were three distal radius fractures, one radio-ulnar shaft fracture, 2 scaphoid fractures, and two meta-carpal fractures. In elbow fractures, there were two supracondyle fractures, and one lateral condyle fracture. There were three epiphyseal plate injuries (Salt-Harris type II) in children, and all of them were treated by conservative method. Six fractures were intra-articular fractures. The most common associated injury was contusion(8cases 42.1$\%$). The number of patients who only rode Inline skating less than 3months(8cases 40$\%$) was the greatest. The number of non-contact injury(14cases, 70$\%$) in Inline skating was more than contact(6cases,30$\%$) injury. 11cases(55$\%$) had operative treatment, and 9cases(45$\%$) had conservative treatment, and there was not any complication. The more detailed study is required since the materials were only limited to fracture patients, and the follow up period was short. Conclusion: The most common age for fracture in Inline skating was in twenties, and thirties, and ankle was the most common fracture site.

Purpose: To evaluate the results of tibial lateral plateau fractures using arthroscopic-assisted reduction and internal fixation without cortical window or bone grafts. Materials and Methods: From March 2009 to March 2017, 27 patients with Schatzker type II tibial plateau fractures with articular depression and displacement over 5 mm on a computed tomography (CT) scan, who were treated with arthroscopic reduction and internal fixation and followed-up for at least 18 months, were enrolled in this study. Under arthroscopic guidance, the depressed fracture fragment was reduced using a freer and fixed with 5.0 or 6.5 mm cannulated screws through the inframeniscal portal without a cortical window or bone graft. The clinical and radiological results were evaluated using a Rasmussen system. Second look arthroscopy was performed in thirteen patients during the implant removal operation. Results: All fractures healed completely with a mean union time of 8.7 weeks (range from 8 to 12 weeks). Twenty four patients had good to excellent clinical results and 25 patients had good to excellent radiological results according to the Rasmussen classification. A well-healed articular surface with fibrocartilage was also found in 13 cases with second look arthroscopy. The 8 cases on CT scan at outpatient department follow-up showed bone union without bone grafting. Conclusion: Arthroscopic-assisted fixation of tibial lateral plateau fractures is a useful method without a cortical window or bone graft that produces good clinical results.

Purpose: To determine how the location, displacement, intra-articular involvement, comminution of a 5th metatarsal base fracture affect results of early weight-bearing treatment. Materials and Methods: From January 2013 to July 2017, 34 cases of 34 patients diagnosed with a fracture of the zone I and II 5th metatarsal base were enrolled. The mean follow-up period was 13 months (6-15 months). One patient was excluded as a refracture during the follow-up period, and 33 patients underwent conservative treatment. Anteroposterior, lateral, and simple oblique radiography and computed tomography of the foot were performed to evaluate the location and displacement of the fracture, the degree of joint involvement, and comminution. In all 33 patients, a short leg cast or boot brace was selected immediately after the injury, tolerable weight bearing was allowed. If the pain disappeared, full weight bearing was performed after wearing a plain shoe or postoperative shoe. As a clinical result, the American Orthopedic Foot and Ankle Society (AOFAS) score was evaluated at the final follow-up. During outpatient follow-up, a simple radiograph of the foot was taken to confirm the time of radiological bone union and return to work. Results: Nine males and 24 females, with an average age of 48.7 years, were enrolled in the study. Twenty-four patients had zone I fractures, and nine patients had zone II fractures. Twenty-two out of 33 patients had a fracture displacement of 2 mm or more. Nine and five patients had joint involvement and comminution, respectively. There was a statistically significant return to work from zone I to zone II. The AOFAS score was excellent at the final follow-up and there was no significant difference. When classifying and comparing the degree of fracture displacement, joint involvement, and comminution, there were no significant differences in the radiological union time and return to work. In all cases, satisfactory results were obtained at the final follow-up. Conclusion: Satisfactory clinical results can be obtained by allowing early weight-bearing regardless of the fracture location, displacement, joint involvement, or comminution in zone I and II 5th metatarsal base fractures.

Purpose: Isolated capitellar fractures are rare, intra-articular fractures requiring an aggressive management regimen. Review the outcome after open reduction and internal fixation of the capitellar fractures. Materials and Methods: From 1998 to 2004, 4 patients with displaced fractures of the humeral capitellum were treated by open reduction and internal fixation of the capitellar fragments with cannulated screws. By use of the criteria of Bryan and Morrey et al, there were 3 type I fractures, 1 type III fracture. A lateral approach was used. The elbows were immobilized postoperatively for 4 to 28 days We evaluated the range of motion, stability, and pain using the criteria of Mayo score. Results: The follow-up period ranged from 12 to 36 months (mean, 15months). Three patients had a stable, pain-free elbow with good range of motion at follow-up. One patient with a neglected capitellar fracture have felxtion cpontracture of 40 degrees with 100 degrees of further felxion(total arc: 60) due to poor compliance to the postoperative rehabilitation. All fractures healed, and there was no evidence of avascular necrosis or degenerative change. Conclusion: Capitellar fractures, rare in case, gave a good result after open reduction and simple internal fixation with cannulated screws without any problem.

Purpose: We wanted to evaluate the clinical and radiological outcomes and the prognosis of various surgical treatments for the distal clavicle fracture with an acromioclavicular joint injury. Materials and Methods: A retrospective study of 21 patients with a minimum of 12 months follow up was done. We classified acromioclavicular (AC) injury into type I (only intra-articular fracture (IAF), 5 cases), type II (IAF with widening of the AC joint > 7 mm, 9 cases) and type III (IAF with AC joint superior subluxation > 50%, 7 cases). The distal clavicle fractures were fixed using plate (9 cases), mini screws (1 case), K wire and tension band wiring (10 cases) and transarticular pinning (1 case). Acromioclavicular or coracoacromial ligament reconstruction was not done in all the cases. Results: In 20 of 21 cases, bone union was achieved at an average of 8.4 weeks. Traumatic arthritis (5 cases), AC joint widening (4 cases) and AC joint subluxation (2 cases) were noted at the last follow up. The average UCLA score was 32.6 in the type I AC joint injuries, 34 in type II and 34.1 in type III. There was no relationship between the clinical outcomes and the preoperative AC joint injury pattern, postoperative traumatic arthritis, AC joint widening or AC joint subluxation (p>0.05). Conclusion: Satisfactory results were achieved by acute reduction and firm fixation of the distal clavicle fracture with AC joint injury. There was no relationship between the pattern of AC joint injury, the residual radiologic findings and the functional outcome.
