Background: Lateral instability of the ankle is one of the most common causes of musculoskeletal ankle injuries. The peroneus longus (PL) and peroneus brevis (PB) contribute to ankle stability. In early rehabilitation, isometric exercises have been selected for improvement of ankle stability. To effectively train the peroneal muscles during eversion, it is important to consider ankle and body posture. Objects: This study aimed to compare activation of the PL, PB, and biceps femoris (BF) muscles during eversion in different ankle postures (neutral [N], plantarflexed [PF]) and body postures (sitting and side-lying). Methods: Thirty healthy individuals with no history of lateral ankle sprains within the last 6 months were included in the study. Maximal isometric strength of eversion and muscle activation were measured simultaneously. Muscle activation at submaximal eversion was divided by the highest value obtained from maximal isometric eversion among the four postures (percent maximal voluntary isometric contraction [%MVIC]). To examine the differences in muscle activation depending on posture, a 2 × 2 repeated measures analysis of variance (ANOVA) was conducted. Results: There were significant interaction effects of ankle and body postures on PL muscle activation and evertor strength (p < 0.05). The PL muscle activation showed a significantly greater difference in the side-lying and PF conditions than in the sitting and N conditions (p < 0.05). Evertor strength was greater in the N compared to the PF condition regardless of body posture (p < 0.05). In the case of PB and BF muscle activation, only the main effects of ankle and body posture were observed (p < 0.05). Conclusion: Among the four postures, the side-lying-PF posture produced the highest muscle activation. The side-lying-PF posture may be preferred for effective peroneal muscle exercises, even when considering the BF muscle.

Inversion injury of the lateral ankle ligaments is very common. Few studies, however, have focused on avulsion fracture of the lateral ankle ligaments. A fracture producing a small fragment usually avulsed from lateral malleolus and may be easily misdiagnosed as a sprain because the fragment is superimposed on the lateral malleolus and goes undetected on early radiographs, especially in skeletally immature patients. We present a case of isolated avulsion fracture of the talar attachment of the anterior talofibular ligament in 13-year-old male patient. Diagnosis was confirmed by computed tomography and avulsed fragment was fixed to original talar footprint with suture anchors. A high level of suspicion must be maintained to obtain an accurate diagnosis of avulsion fracture in inversion ankle injury because of the high incidence in children and to prevent recurrent instability.

Purpose : The purpose of this study was to investigate the effects of the virtual reality exercise program on ankle balance with ankle taping or microwave. Methods : This study was performed on 18 subjects. Eighteen subjects were divided into two groups; conducted virtual reality exercises with taping (n=9), and performed virtual reality exercises after microwave application (n=9). Both groups performed the exercise three times a week for four weeks. The data was analyzed by the Wilcoxon signed-rank test for comparing before and after changes of factors in each group and performed the Mann-Whitney test for comparing groups. Result : Taping and microwave groups were increased dynamic balance after virtual reality exercises (p<.05). There was no significant difference in balance after applying taping and microwave for virtual reality exercises (p<.05). Conclusion : Reducing the frequency of recurrent ankle sprain in functional ankle subjects, it is recommended to perform virtual reality exercise after applying taping and microwave.

Objective: Epidemiological research shows that 47 to 73% of athletes suffer from recurrent ankle sprains. Joint mobilization techniques (JMT) implemented in correcting may be beneficial in the management of ankle injuries. The purpose of this study is to examine the immediate JM on ankle complex as clinical measures in individuals with chronic ankle instability (CAI) through intervention. Method: Thirteen subjects with CAI (8 males and 5 females) participated in this study. Each subject tried total four alignments (Navicular drop test: NDT, Standing rearfoot angle: SRA, Tibia torsion: TT, and dorsiflexion range of motion: DFROM). The participants were performed the 10 meter shuttle run after JMT for post-task. Finally, it was tried to compare between pre-post tasks after shuttle run. Results: SRA and DFROM after intervention showed significant differences. SRA (p=.026), and DFROM (p=.034). Conclusion: We concluded that the JMT has resulted in improvement in SRA, DFROM. Increased DFROM and varus shapes of foot would be closed kinetic chain, indicating that reduce the risk factors of ankle sprain. Future study needs to be conducted in order to measure the effects of prolonged intervention of JMT.

Concurrent injury of medial malleolus and deltoid ligament is difficult to occur considering the injury mechanism. When the concurrent injury comes about, the deltoid ligament injury could be missed and it may lead to medial ankle instability. There are few reported cases of the concurrent injury and domestic case of concurrent failure of both structures over the medial side has been reported just once; however, the injury mechanism is different from this case. The authors report a case of medial malleolus fracture with deltoid ligament rupture following pronation injury with a review of necessity of repairing deltoid ligament for ankle stability.

Fracture of os peroneum can occur, but the fracture fragments are seldom displaced. Complete rupture of peroneus longus through the fracture of the os peroneum causing displacement of the fracture fragments is not well reported in the literature. Differential diagnosis with bipartite os peroneum or calcific tendinitis is important because misdiagnosis of the tendon rupture can lead to serious sequela including chronic pain, ankle instability, and peroneal compartment syndrome. We report a case of complete rupture of peroneus longus associated with fracture of the os peroneum with a review of the literature.

Purpose: The diabetic charcot neuroarthropathy of ankle is an infrequent site (around 5%), but is definitely the location that, because of the instability and progressive deformity it involves, cause ulceration in a high percentage of patients, and this can then become a reason for amputation. However, the treatment of this disastrous disease is still challenging. We analyzed the clinical and radiological results of ankle arthrodesis by our fixation method in Charcot neuroarthropathy. Materials and Methods: Seven cases that were diagnosed as charcot neuroarthropathy of ankle arthrodesis were followed for more than 16 months postoperatively. Mean age was 57 years, and the mean follow-up period was 27 months. Anterior approach was used in arthrodesis, and internal fixation by 3 or more cannulated screws and hybrid type external fixation were used. Auto iliac bone for grafting was combined in all cases. External fixator was kept for 3 months without weight-bearing. Then, boots brace was applied for more 3 months allowing partial weight-bearing. Four cases had minor complications such as pin site infection. Preoperative and postoperative AOFAS score, time to fusion and postoperative complications were checked. Results: Postoperative fusion was completed in all cases, and the mean time to fusion was 3.4 months. No postoperative complication was checked. At the last follow-up, the mean AOFAS score had increased from 54 points to 72 points. Patient's satisfaction was over 80%. Conclusion: Satisfactory results were obtained after ankle arthrodesis using internal and hybrid type external fixation combined with auto iliac bone graft in charcot neuroarthropathy with minor complications.

Purpose: Foot and ankle disease (FAD) is a frequent cause of morbidity among the homeless population. Various conditions, exacerbated by malnutrition, poor lifestyle habits, psychiatric disorders, physical injuries, poor hygiene, and limited access to healthcare, have been described in this population. The purpose of this study was to investigate the cognition and management status of FAD in shelter based homeless people. Materials and Methods: Fifty-two male and twenty-five female volunteer homeless individuals were recruited from two homeless shelters. Each person completed a questionnaire assessing any presence of pain, pain management, as well as foot and ankle care status. A foot and ankle surgeon examined the physical status of the individual's foot and ankle, including tenderness and instability. A radiologic evaluation was done for 18 male and 11 female homeless people who agreed to participate in this test for the existence osteophyte or joint space narrowing representing osteoarthritis and some reference angles for hallux valgus, flatfoot and cavus foot. Results: Homeless people had higher prevalence of body mass index, diabetes, and smoking than the general population. The most prevalent infectious disease was fungal infection (male 78%, female 68%), with a low compliance of management for FAD. Conclusion: Although most of shelter-based homeless people showed an acceptable foot and ankle management status, the potential risk for FAD development and exacerbation of mild FAD was high.

Purpose: To investigate clinical features and treatment of os subfibulare Materials and Methods: This is a retrospective study on twenty-eight patients who have symtoms associated with os subfibulare. We reviewed charts and radiographs. Thirteen patients were treated surgically and fifteen patients were treated conservatively. We analysed clinical results in 25 patients who were followed for more than one year. Results: Duration from the onset of symtoms to treatment was more than six months in twelve of thirteen surgically treated cases, and in only two of fifteen conservative treated cases. Surgical procedures were internal fixation of the os subfibulare in two patients, and resection of os subfibulare and ligament reconstructions in eleven patients. Clinical results were excellent in six, good in three and poor in two of operatively treated patients. In conservatively treated patients, five excellent, five good, one fair and one poor clinical results were obtained. Conclusion: Os subfibulare is not necessarily a cause of instability and pain, but in cases with chronic pain and/or instability, surgical treatment would result in satisfactory result.
