The purpose of this study was to compare and analyze the difference of the ankle joint movements during landing. Seven adult males voluntarily participated in the study and the average foot size of the subjects was 269.8 mm. Image analysis equipment and the ground reaction force plate (landing type) was used to measure th kinetic variables. As a result of this study, it was confirmed that the vertical ground reaction force peak point appeared once in the barefoot with forefoot, while two peak points appeared in the barefoot and functional shoe foot with rear foot landing. About ankle angle, fore foot landing ankle angle, the average with bare foot landing was $-10.302^{\circ}$ and the average with functional shoe foot landing was $-2.919^{\circ}$. Also about rear foot landing, ankle angle was $11.648^{\circ}$ with bare foot landing and $15.994^{\circ}$ with functional shoe landing. The fore foot landing, ankle joint force analysis produced 1423.966N with barefoot and 1493.264N with functional shoes. But, the rear foot landing, ankle joint force analysis produced 1680.154N with barefoot and 1657.286N with functional shoes. This study suggest that the angle of ankle depends on the landing type and bare foot running/functionalized shod running, and ankle joint forces also depends on landing type.

Calcaneal fractures account for 2% of all fractures and approximately 60 to 70% of tarsal fractures. These fractures typically are the result of high-energy injury, such as a motor vehicle accident or a fall from a height. The potential for disabling malunion following intrarticular displaced calcaneal fracture is high, regardless of treatment. Fracture displacement typically results in loss of hindfoot height, varus and widening of the hindfoot, with possible subfibular impingement and irritation of the peroneal tendon and/or sural nerve. Frequently, subtalar joint develops posttraumatic arthritis. In symptomatic patients with calcaneal malunion, systemic evaluation is required to determine the source of pain. Nonsurgical treatment, such as activity and shoe modification, bracing, orthoses, and injection, is effective in many patients. Surgical treatment may involve simple ostectomy, subtalar arthrodesis with or without distraction, or corrective calcaneal osteotomy. A high rate of successful arthrodesis and of patient satisfaction has been reported with surgical manamgent.

The effects of acupuncture treatment and taping therapy on a 22-year-old man who suffered from left foot pain due to Lisfranc joint injury were examined. Fractures of the first, second, and third metatarsal bones and a cuneiform bone were treated with acupuncture and taping therapy from March 24, 2017 to May 4, 2017. The patient was evaluated using the American Orthopaedic Foot & Ankle Society's Ankle-Hindfoot Scale. His Ankle-Hindfoot Score increased from 27 points pre-treatment to 65 points post-treatment. There were no side effects. While the improvement observed in this patient is encouraging, no definitive conclusion on the effects of acupuncture treatment and taping therapy on Lisfranc joint injuries can be reached without further large-scale study.

Acute subluxation of the peroneal tendon is an uncommon injury which is predominantly associated with a trauma. Traumatic peroneal tendon subluxation in athletes is an uncommon cause of ankle pain. As a result, the diagnosis is often delayed. Numerous surgical techniques have been described for chronic peroneal subluxation or dislocation, however reports in acute cases are rare. Authors experienced two cases of acute subluxation of peroneal tendon in athletes which were treated by simple primary repair of superior peroneal retinaculum with good results.

Traumatic dislocation of the peroneal tendon is a rare injury. It should be distinguished from other conditions that can cause pain and disability of lateral aspect of the ankle joint. We experienced a case of chronic recurrent dislocation of the peroneal tendon, which was treated by deepening of the peroneal groove of the lateral malleolus and reattachment of the superior peroneal retinaculum. The clinical result was satisfactory.

Background: The gastrocnemius (GCM) is one of the lower extremity muscles that tend to tighten easily. GCM tightness results in limited ankle dorsi-flexion (DF), especially when the knee joint is fully extended. Joint flexibility is determined by the morphological and physiological characteristics of joints, muscles, tendons, and ligaments. Impaired joint flexibility can be attributed to increased susceptibility to muscle injury. High-frequency diathermy is clinically used to reduce pain and muscle tightness and to improve limited range of motion. Objects: This study aimed to investigate the immediate effects of high-frequency therapy in subjects with GCM tightness. Methods: The study was designed as a one-group before-after trial. The subjects included 28 volunteers with GCM tightness (an active ankle DF angle of less than 12°) without any known neurological and musculoskeletal pathologies in the ankle and calf areas. WINBACK Transfer Electrode Capacitive and Resistive Therapy equipment was used to apply high-frequency therapy to the subjects' GCMs for 10-15 minutes. The pennation angle and the fascicle length of the GCM were measured using ultrasonography. The flexibility of the ankle joint, peak torque to the passive ankle DF (Biodex), and soft tissue stiffness (MyotonPRO) were also measured. Results: The pennation angle was significantly decreased following the treatment; however, no significant difference in the fascicle length was found (p < 0.05). The flexibility was significantly increased and both the passive peak torque to passive ankle DF and the soft tissue stiffness significantly decreased (p < 0.05). Conclusion: High-frequency therapy is immediately effective for improving the muscle's architectural properties and functional factors in subjects with GCM tightness. Further longitudinal clinical studies are required to investigate the long-term effects of high-frequency therapy on subjects with GCM tightness from various causes.

Purpose: We compared the clinical features of the ankle fractures treated by operation between the elderly and the young, and reviewed the principles of treatment of the ankle fractures in the elderly. Materials and Methods: We reviewed 49 cases of the ankle fractures, which were treated by open reduction from August 1991 to July 2002. Patients aged more than 60 were designated as the elderly, and patients aged between 15 and 33 were designated as the young. The average follow-up period was 13.2 months. Using the Lauge-Hansen classification, We defined stage I or II fractures as low stage and stage III or IV fractures as high stage fractures. Results: There were 15 cases of high stage fractures (78.9%) in the elderly and 11 cases (36.7%) in the young. High stage fracture rate was significantly higher in the elderly (P=0.004). Hospital day, period between primary injury and operation, and union time were significantly longer in the elderly (P<0.001). However, there was no statistical difference in immobilization time between the two groups. The results of treatment were satisfactory clinically and radiologically by the Meyer's criteria in both groups. Conclusion: In the elderly, high stage fractures were more common and longer hospitalization and union time were needed than the young. However, the result of surgical treatment was satisfactory.

Purpose: The purpose of this study is to investigate the usefulness of ultrasound-guided femorosciatic nerve block by orthopaedist to operate the fracture around ankle. Materials and Methods: Twenty-two patients, who had an operation for fracture around the ankle under a ultrasound-guided femorosciatic nerve block from January to April 2010, were the targets of this study. We measured the time spent for the ultrasound-guided femorosciatic nerve block, the time taken to start the operation after the nerve block, the time taken to deflate the tourniquet because of a tourniquet pain, the time passed until feeling a postoperative pain after the operation, etc. We also studied the complications and satisfaction of the anesthesia. Results: It took 6.2 (3 to 12) minutes for the nerve block, 46.1 (28 to 75) minutes to start the operation, 52.5 (22 to 78) minutes until feeling a tourniquet pain and 11.5 (7.5 to 19) hours until starting to feeing a postoperative pain. There was no complication by anesthesia and 21 people (95.5%) were satisfied with anesthesia by ultrasound-guided femorosciatic nerve block. Conclusion: Ultrasound-guided femorosciatic nerve block by orthopaedist in the fracture around ankle reduces anesthetic and nerve injury complication, and leads to high anesthetic success rate. Also it is considered as an effective method to alleviate postoperative pain.
