Purpose: One of the main contributors to proximal fifth metatarsal fracture is ankle inversion and the incidence of recurrence may increase in patients with ankle instability. So, the authors confirmed the patients of proximal fifth metatarsal fracture with ankle instability by checking the history and magnetic resonance imaging (MRI) and assessed the value of MRI as therapeutic prognosis and clinical indicators for prevention of recurrence. Materials and Methods: Patients with proximal fifth metatarsal fractures visited our hospital during recent five years were reviewed. 35 patients with suspected damage by ankle inversion had been identified a history of ankle instability and checked the hindfoot malalignment through hindfoot alignment view and MRI was performed prospectively. The patients was devided to three groups on the location of fracture site and the groups were compared each other. Results: The mean time from injury to checking MRI was 10.7 days. There was no structural abnormality and was no significant difference according to the location of fracture. The patients with history of ankle inversion were 31(88.6%) and the patients with history of chronic or recurrent injury were 22 patients (62.9%). The lesion of MRI related to lateral ankle instability were identified in all patients. Conclusion: This study noted a high incidence of lateral ankle instability that was identified by MRI in the patients of proximal fifth metatarsal fracture. Aggressive treatment for lateral ankle instability should be needed for complications as proximal fifth metatarsal fracture to reduce the recurrence and occurrence.

Background : Ankle inversion sprains are one of the most common injuries in sports and activities of daily living that mostly concern physically active individuals. In most researches, proprioceptive deficit, muscle weakness and/or absent coordination have been regarded as a contributing factors. Despite the high incidence of ankle sprain and instability, therapeutic approaches to properly manage the symptoms have rarely been investigated. This study aimed to identify the effect of proprioceptive exercise program that is easy to integrate in normal training program. Methods : Subjects were randomly allocated to control group and experimental group consisting of 11 and 10 patients, respectively. The conservative treatment for the control group consisted of hot packs, ultrasound and TENS. In addition, the experimental group performed 7 exercises to enhance proprioceptive function of ankle joint. The therapeutic intervention of the controland experimental groups was performed a total of 20 exercise sessions, averaging 50 hour each, 5 times per week for 4 weeks. To compare the two groups, the level of ankle disability was assessed by using the ankle injury score scale in pre- and post-treatment. Results : On assessment of post-treatment, there were statistically significant differences in the scores of all sub-items, except for ankle laxity and range of motion, and the total score of ankle injury score scale between the two groups(p<0.05). In comparison between pre- and post-treatments, the significant difference in the scores of all sub-items and total score didn't appear for the control group, while the scores of most sub-items and total score of the experimental group were shown the statistically significant difference(p<0.05). Conclusion : The findings suggest that the proprioceptive exercise program is more effective for relieving ankle disability than conservative treatment therefore, the program to improve proprioceptive function should be recommended for prevention and rehabilitation of recurrent ankle inversion injuries.

Purpose: A distal tibiofibular syndesmosis injury with an ankle fracture is usually fixed with syndesmotic screws. Knotless Tightrope$^{(R)}$ has been used as an alternative procedure because of the fewer reported complications. Therefore, this study compared the two surgeries. Materials and Methods: Forty-two patients, who underwent syndesmotic screw fixation, and 34 patients, who underwent Knotless Tightrope$^{(R)}$ fixation for distal tibiofibular syndesmosis injury from February 2014 to February 2016, were analyzed retrospectively. The visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, range of motion of ankle at 1 year after surgery, tibiofibular clear space, and tibiofibular interval at preoperative, postoperative and 1 year after surgery were investigated. Results: The VAS score, AOFAS score and radiographs were similar in the two groups. Knotless Tightrope$^{(R)}$ showed better results in complications and plantarflexion. Conclusion: Knotless Tightrope$^{(R)}$ fixation is a useful treatment that does not show a difference in fixation strength and clinical outcome. Knotless Tightrope$^{(R)}$ fixation also has an advantage in the range of motion and complications.

Ankle sprains are among the most common injuries sustained during athletic activities and daily life. Acute ankle sprain is usually managed conservatively with functional rehabilitation but the failure of conservative treatment leads to the development of chronic ankle instability. The development of repetitive ankle sprains and persistent symptoms after injury has been termed chronic ankle instability. Acute ankle sprains and chronic ankle instability require a careful evaluation to detect other comorbidities, such as subtalar instability, osteochondral defect, peroneal tendinopathy, tarsal coalition, os trigonum, flexor hallucis longus tendinitis, calcaneus anterior process fracture, and neural injuries. For the successful treatment of acute ankle sprains and chronic ankle instability, the treatment of comorbidity lesions should be performed first.

The purpose of this study was to identify the effect of the subtalar sling ankle taping, by measuring changes in peak plantar pressure and subtalar angle during jump landing and walking in healthy subjects with subtalar sling ankle taping applied of the ankle joint. Fifty healthy subjects(8 males and 7 female, aged 22 to 25) were randomly divided into a participated in this study. They were free of musculoskeletal injury and neurologic deficit in lower extremity. The subjects were asked to perform 5M walking and single leg jump landing by under the guidance of physical therapists. Subtalar motions were typically measured as the angle made between the posterior aspect of the calcaneous and the posterior aspect of the lower leg during walking with taping or not. This measurement were made using a video system (30Hz sampling rate, rectified 60 Hz sampling rate). At the same time, peak lateral and vertical pressure were investigated using pressure distribution platforms(MatScan system) under foot during walking and single leg jump landing with taping or not. Statistical analysis was done by paired t-test and intraclass correlation coefficient [ICC(3.1)], using software SPSS. We have recently demonstrated significantly altered patterns of subtalr joint and peak plantar pressure when applied subtalar sling ankle taping(p<.05). Inversion angle of subtalar joint significantly decreased with taping(p<.05). The result suggest that pressure patterns observed in subjects are likely to result due to significant decrease in stress on ankle joint structures during jump landing and walking. Also, the result that the subtalar sling ankle taping procedure provides greater restiction of motion associated with ankle inversion. However, this study involved asymptomatic subjects without history of ankle inversion injury, further research is needed to assess the motion restraining effect of the subtalar sling ankle taping in subjects with lateral ankle instability.

Tillaux fractures, a rare type corresponding to Salter-Harris type 3, are observed in approximately 3% of pediatric ankle fractures. They are known to occur primarily via a supination-external rotation mechanism. Maisonneuve fractures, on the other hand, are proximal fibula fractures involving injury on syndesmosis, deltoid ligament, or medial malleolus fracture, occurring via a pronation-external rotation mechanism. These two types of fractures occur through different mechanisms of injury. In this study, a nine-year-old female pediatric patient presented to the outpatient department with ankle pain following a fall from a trampoline and was diagnosed with concurrent Tillaux-like fracture and Maisonneuve fractures. Surgical treatment was performed, resulting in successful recovery.

Authors report one patient of concurrent fracture of medial malleolus and rupture of deltoid ligament. To the author's knowledge, combined failure of both structures has not been previously reported in Korea. Injury mechanism was classified into pronation -abduction type according to Lauge-Hansen classification. Plain radiograph revealed trimalleolar fracture and posterior ankle dislocation. MRI showed complete rupture of both deep and superficial layer of the deltoid ligament. In conclusion, therefore, concurrent rupture of deltoid ligament should be considered for the surgical treatment in trimalleolar ankle fracture with posterior ankle dislocation resulted from pronation-adduction injury.

Fracture and fracture-dislocation of the ankle may be caused by a variety of mechanisms. In addition to the fracture, injury of soft tissue such as ligaments, tendons, nerves, and muscles may occur. Among these, tibialis posterior tendon injury is difficult to identify due to swelling and pain at the fracture site. There is no clear finding in radiological examination, therefore, it is found during surgery. In this case, irreducible fracture-dislocation of the ankle due to tibialis posterior tendon interposition was observed after the primary operation. The authors obtained satisfactory results in performance of a secondary operation assisted with arthroscopy.

Objective: Few studies have investigated alterations of ground reaction force (GRF) in individuals with chronic ankle instability (CAI) compared with lateral ankle sprain (LAS) copers and healthy controls during walking. This study aimed to investigate differences in GRF variables among the CAI, LAS coper, and control groups. Method: Eighteen individuals with CAI, 18 LAS copers, and 18 healthy controls were recruited for this study. All participants walked on 8-m walkway with a force plate three times. GRF data during stance phase were extracted and analyzed. The analysis of variance and ensemble curve analysis were used for statistical analyses of discrete points and time-series data respectively. Results: The CAI group showed a greater loading rate (LR) and a shorter time to impact peak force than the other groups, as well as decreased vGRF from 56% to 65% in the stance phase than the control group. No significant differences were noted in the other variables. Conclusion: Based on these findings, individuals with CAI should enhance their ability to create propulsion during the push-off phase and spend more time absorbing GRF to decrease the LR, which is considered one of risk factors for overuse injury and ankle osteoarthritis.
