The purpose of this study was to determine suitable angle of Tibia-foot and the X-ray tube for scaphoid in foot X-ray examination. A total of twenty patients(mean age $32.12{\pm}years)$ are participated in this study. In the positions of Foot AP, internal and external oblique, tibia-foot angle was defined as $90^{\circ}$ and $135^{\circ}$, and x-ray tube angle was defined as $0^{\circ}$, $5^{\circ}$, $10^{\circ}$, $15^{\circ}$ and $20^{\circ}$ respectively. The image quality was evaluated with blind test yielding scores ranging from 0 to 5 by the evaluation team consisted of 2 radiogical technologists, 2 radiologists, and 2 orthopedic surgeons. In case of Foot AP position, the degree of overlap between cuneiform and navicular was 3% and the blind test result was 4.89 at tibia-foot angle of $90^{\circ}$ and $15^{\circ}$ X-ray tube angle. When the tibia-foot angle is $135^{\circ}$, the degree of overlap was 5%, also the blind test result was 4.30 at $15^{\circ}$ X-ray tube angle. The degree of overlap and blind test result were 30% and 3.75 respectively at $0^{\circ}$ X-ray tube angle. In case of internal oblique position, at tibia-foot angle of $90^{\circ}$ and $0^{\circ}$ X-ray tube angle, the degree of overlap was 4% and the blind test result was 4.70. The 5% overlapping and highest score as 4.55 were obtained on tibia-foot angle of $135^{\circ}$ and $0^{\circ}$ X-ray tube angle. In case of external oblique position, at tibia-foot angle of $90^{\circ}$ and $15^{\circ}$ X-ray tube angle, the degree of overlap was 4% and the blind test score was 4.85. The 5% overlapping and highest score as 4.75 were obtained on tibia-foot angle of $135^{\circ}$ and $15^{\circ}$ X-ray tube angle. In conclusion, we confirmed suitable angle of tibia-foot and X-ray tube for scaph46oid in foot X-ray examination in this study. These findings will be helpful for us to reading for navicular fracture.

Fracture of the carpal scaphoid bone is the most common fracture of the carpus. Unfortunately. nonunion are common since the symptoms do not alert patients to seek early medical treatment and the diagnosis is easily missed. Fracture of the scaphoid is a common condition whose management remains controversial. The conservative treatment has many complications, these include inability to work while in plaster, stiffness of the wrist afterwards, muscle wasting, weakness and malunion. So various operative treatments of scaphoid fracture have been developed. Open reduction by use of screws suggested by Maclaughlin first in 1954. In 1984 a new and simple operative technique has been developed to provide rigid internal fixation for all types of fractures of the scaphoid by T.J. Herbert. This involves the use of a double-treaded bone screw which provides good fixation that, after operation, a plaster cast is rarely required and most patients are able to return to work within a few weeks. Authors have experienced 10 cases of scaphoid fracture and accomplished good result in all cases by internal fixation using Herbert screw. The results are as follows : Of these 10 fractures, 2 were fresh fractures and 8 were non unions of scaphoid fracture. In nonunion cases, the time interval between fracture and operation was from 5 months to 5 years. The postoperative immobilization period was average of 4 weeks. Short period of immobilization achieved early functional recovery of the wrist. The bony unions in roentgenogram were seen from 3 months to 9 months after operation. In 2 cases the fracture gap was seen after 9 months. But in these cases the symptoms such as pain and range of motion of wrist were improved.

Purpose: Radiocarpal dislocation (RCD), which is caused by high-energy trauma, often involves radial styloid fractures and short radiolunate ligament (SRLL) injuries. Although SRLL injuries may occur as a simple rupture at the attachment site of radius, it may occur with a relatively large avulsed-fragment in the volar rim of the lunate facet of the radius. This study aimed to differentiate the injury type of SRLL and assess the differences in the treatment results depending on the treatment methods that have been applied in RCD with radial styloid fractures. Materials and Methods: Eighteen patients managed surgically with RCD were enrolled in this study. The patients were classified as Group 1 and Group 2 by using the Dumontier method. In this study, Group 2 was subdivided into 2A (purely ligamentous or small avulsion fracture of the volar rim of lunate facet) and 2B (large avulsed-fragment enough to internal fixation) according to the injury type of SRLL. Groups 2A and 2B were treated with direct repair and screw fixation, respectively. Pain, range of motion of the wrist joint, grip strength, and complications on final radiographs were examined. The outcomes were evaluated using patient-rated wrist evaluation (PRWE), and modified Mayo wrist score (MMWS). Results: All patients were Group 2 (six and twelve patients in 2A and 2B, respectively). The mean flexion to extension arch recovered 79%,and the mean grip strength was 72.9% of the uninjured side. Group 2A showed better recovery in extension, flexion and pronation than Group 2B, but there was no difference in radial deviation, ulnar deviation, supination, grip strength and pain. No differences in the PRWE and MMWS were observed between two groups. Complications included traumatic arthritis in seven patients and residual instability in five patients. Conclusion: When the SRLL was injured, the involvement of a large avulsion fracture on the anterior plane of the radiolunate did not affect the test results. On the other hand, it should be observed cautiously because avulsion fractures tend to disturb the joint's reduction through rotation or displacement. In addition, anatomical reduction and sturdy internal fixation are important for restoring the function of the SRLL.

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: Korean studies on the prevalence of a tarsal coalition are quite rare, and there are very few reports on the prevalence of multiple tarsal coalitions among adults in the foreign literature. Therefore, this study examined the characteristics and prevalence of tarsal coalition in the Korean population based on imaging tests. Materials and Methods: The prevalence of tarsal coalition and its anatomical location and histological classification were reviewed retrospectively among 4,711 patients (4,454 males and 257 females) with an ankle sprain or ankle fracture who underwent foot and ankle computed tomography and magnetic resonance imaging between March 2009 and February 2019 at the authors' institution. Results: Over a period of 10 years, 78 patients (1.7%) had a tarsal coalition, among whom 53 patients (67.9%) had an isolated tarsal coalition and 25 patients (32.1%) had multiple tarsal coalitions. Regarding the anatomical location, a talocalcaneal coalition was the most common type in both isolated (31 patients, 37 cases [62.7%]) and multiple (22 patients, 23 cases [45.1%]) tarsal coalitions. In the isolated coalition group, the second-most common type was calcaneonavicular coalition (10 patients, 16.9%), followed by naviculocuneiform (nine patients, 15.3%) and cuboidonavicular coalitions (three patients, 5.1%). In the multiple coalition group, the second-most common coalition type was calcaneonavicular coalition (14 patients, 14 cases [27.5%]), followed by talonavicular coalition (six patients, six cases [11.8%]). From a total of 60 cases of talocalcaneal coalition, 24 cases (40.0%) were in the posterior facet, 18 cases (30.0%) in the middle facet, and four cases (6.7%) in the anterior facet. Regarding the histological classification, cartilaginous coalition was the most common in both single (32 patients, 35 cases [59.3%]) and multiple (20 patients, 37 cases [72.5%]) coalition groups. Conclusion: The present study found that talocalcaneal coalition was the most common type of tarsal coalition. In contrast to previous reports that a talocalcaneal coalition generally occurs in the middle facet, it was usually observed in the posterior facet in the present study. In addition, although multiple tarsal coalitions have been reported to be quite rare, this study confirmed that they are not rare and can occur in a range of patterns.

The purpose of this article is to evaluate and analyze diagnosis and the clinical result of avulsion fracture of navicular. Eight patients operated from Jan. 1991 to June 2002 were evaluated retrospectively. Clinical tolerability, AOFAS score, patient's satisfaction were evaluated. Preoperative AOFAS score is $59.88{\pm}10.90$. Postoperative AOFAS score is $94.75{\pm}6.11$. All patient satisfied result of operation, and 5 patient return to training wihin 3 month. Navicula avulsion fracure is relatively rare. The small dorsal bone triangular fragment is best seen in lateral view radiographs and bone scan and/or computed tomography help corfirm diagnosis. Operative treatment is the method of choice because of shorter recovery time. Simple excision is enough to get a good clincal outcome.

Purpose: The aim of this study is to evaluate the effectiveness of surgical treatment in adolescent patients suffering from navicular stress fracture. Materials and Methods: A total of 11 adolescent patients aged 14 to 19, who underwent an operation for navicular stress fracture between 2005 and 2008 were recruited. Clinical outcomes were evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and visual analogue scale (VAS) score. Results: The mean VAS score before the operation was 7.7. A score of 2.9 was confirmed at final follow up after the operation. The mean final follow-up period was 22.1 months. There was a statistically significant improvement in the VAS score between before and after the operation (p=0.01), and similarly, the AOFAS score also showed an improvement, from 46.5 to 80.7 (p=0.01). The pain that remained after the operation, according to the VAS score, was severe in three patients (27.3%), tolerable in seven patients (63.6%), and free of pain in one patient (9.1%). Conclusion: In navicular stress fracture in adolescents, careful selection of patients who could benefit from surgical treatment is recommended.
