Purpose: The clinical and radiological results of patients with type 3 talar neck fractures treated with the anteromedial approach using medial malleolar osteotomy and large distractor were analyzed retrospectively. Materials and Methods: From March 2009 to August 2016, 12 patients with a type 3 talar neck fracture, who underwent the anteromedial approach using a medial malleolar osteotomy and large distractor and who could be followed-up for more than 12 months after the operation, were examined. The patients were examined for the presence of Hawkins signs by anteroposterior and lateral radiographs and osteonecrosis by magnetic resonance imaging (MRI) on the postoperative 3 months. Subsequently, every 3 months, radiographic union was assessed by a simple radiograph and clinical symptoms. Twelve months postoperatively, posttraumatic arthritis was assessed and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was analyzed. Results: In 7 cases, osteonecrosis was found on MRI performed 3 months after surgery. On the other hand, at the 12 months follow-up, all of them obtained AOFAS scores of 83.86±4.53 without surgical treatment. Radiographic union was achieved in all cases. The mean union period was 5.3 months. In 10 cases, traumatic arthritis was found after the radiographical and clinical evaluation. In addition, all of them could carry on everyday life by conservative treatment. The AOFAS ankle-hindfoot score was measured to be 85.17 on average. Other complications included superficial wound infection in 2 cases. Conclusion: An anteromedial approach using a medial malleolar osteotomy and a large distractor in the surgical treatment of patients with type 3 talar neck fractures can achieve anatomical reduction of the displaced fragment without a lateral dissection. This is considered to be another good surgical option.

The study was designed to identify any trends of injury type as it relates to the age and trade of construction workers. The participants for this study included any individual who, while working on a heavy and highway construction project in the Midwestern United States, sustained an injury during the specified time frame of when the data were collected. During this period, 143 injury reports were collected. The four trade/occupation groups with the highest injury rates were laborers, carpenters, iron workers, and operators. Data pertaining to injuries sustained by body part in each age group showed that younger workers generally suffered from finger/hand/wrist injuries due to cuts/lacerations and contusion, whereas older workers had increased sprains/strains injuries to the ankle/foot/toes, knees/lower legs, and multiple body parts caused by falls from a higher level or overexertion. Understanding these trade-related tasks can help present a more accurate depiction of the incident and identify trends and intervention methods to meet the needs of the aging workforce in the industry.

Insulin resistance is a risk factor for stroke or recurrent stroke. Sedentary behavior increases insulin resistance. This study aimed to identify the relationship between physical impairments and functions and insulin resistance, examining which physical impairments specifically influence insulin resistance the most. The subjects of this study were 63 stroke patients. The subject's insulin resistance and physical impairments and functions were measured using the Chedoke-McMaster Stroke Assessment (CMSA) and Stroke Impairment Assessment Set (SIAS). The study results exhibited that insulin resistance is statistically significantly related to the variable of foot according to the CMSA(r=.95, p<.05) and to the variable of lower extremity sensory function (touch) in relation to the SIAS(r=.91, p<.05). This study also revealed close correlations between insulin resistance and the variables of ankle control(${\beta}=-1.05$, p<.05) and low extremity tactile sensations(${\beta}=-1.82$, p<.05).

Cutting movements frequently occur in sports and influence much Lower Extremity injuries. The purpose of this study was to compare joint motion of lower extremities to cutting angles and running velocities. Seven male subjects performed cutting movements to three angles($0^{\circ}$, $30^{\circ}$, $60^{\circ}$). Subjects were instructed to run five meters at a speed of 2.5m/s and 4.5m/s before contacting their right foot on the force plate and then change direction to the left. The Peak hip, knee and ankle joint kinematics were influenced according to the running velocities and cutting angles. In conclusion, Fast running velocity and cutting angle will may influence on the lower extremity joint instability on real game situation.

This paper describes the possibility of analyzing gait pattern from the variation of the lower leg electrical impedance. This impedance is measured by the four-electrode method. Two current electrodes are applied to the thigh and foot., and two potential electrodes are applied to the lateral aspect. medial aspect, and posterior position of lower leg. We found the optimal electrode position for knee and ankle joint movements based on high correlation coefficient, least Interference, and maximum magnitude of impedance change. From such features of the lower leg impedance, it has been made clear that different movement patterns exhibit different impedance patterns and impedance level.

Objectives : This study aimed to introduce a new traction therapy and proposes that a new Chuna manual therapy technique could be implemented. Methods : The patient is placed in the prone position and their ankle is fixed to the fixing table. Next, clinicians contact on the vertebral spinal process above herniated disc region with the tissue pulled head part of scaphoid bone and the lower part of the pelvis is pulled horizontally to the foot. Conclusions : It was recently identified that traction while maintaining lumbar lordosis is more effective for lumbar disc herniation and is associated with fewer side effects. Chuna manual therapy also uses a technique of lumbar flexion-distraction manipulation to treat HIVD. further research is required.

A ganglion is a benign cystic mass, commonly found around a joint or tendon sheath. It frequently occurs at the wrist, foot, ankle, and knee. Intratendinous ganglion has been rarely reported, and intratendinous ganglion of the long head of biceps brachii is extremely rare. According to our literature review, this is the third case of intratendinous ganglion of the long head of biceps brachii, and the first case of arthroscopic treatment. Therefore we report a case of an arthroscopic treatement for an intratendinous ganglion of the long head of biceps brachii.

This study is to observe the effect of Korean medicine treatment combined with electro-acupuncture and chuna manual treatment on tarsal tunnel syndrome inpatient. The patient, diagnosed as tarsal tunnel syndrome, was treated by Korean medicine treatment in combination with electro-acupuncture and chuna manual treatment. We measured visual analogue scale(VAS). Neuropathic pain scale(NPS) was adopted as a method of measuring the treatment results of pain & hypoesthesia. Rt. sole numbness & pain decreased from VAS 10 to VAS 4. Rt. foot paresthesia decreased from VAS 10 to VAS 4 and Rt. ankle pain was disappeared. NPS score decreased from 80 to 62. Korean medicine treatment in combination with electro-acupuncture and chuna manual treatment is proved to be helpful to improve the symptoms of the tarsal tunnel syndrome patient.
