Purpose: To evaluate the clinical and functional results of ankle arthroplasty and to analyze the complications in total ankle arthroplasty. Materials and Methods: Between October 1988 and October 1991, the total ankle arthroplasty had been performed in eight ankle joints of seven patients.. There were five patients with rheumatoid arthritis, one with osteoarthritis and one with traumatic arthritis. One patient had bilateral replacement. New Jersey type of prosthesis was used in six patients and one patient was performed with Odland type of prosthesis. The average age at surgery was 42.3 years (range, 33-54 years). The average follow-up period was 8.2 years (range, 6-10.5 years). Clinical evaluation was assessed according to the Ankle-Hind Foot Scale of American Orthopedic Foot and Ankle Society. Results: The average score was 81.4 (range, 76 - 90) at the most recent follow-up. All patients were satisfied with their clinical results. Relief of pain was excellent in most patients, but postoperatively there was no significant improvement in range of motion. One patient had arthrodesis at three year six months after total ankle arthroplasty due to deep infection. Conclusion: This study shows total ankle arthroplasty is a good alternative treatment in selected cases of osteoarthritis and rheumatoid arthritis.
Objective : Although minimally invasive posterior cervical foraminotomy (MI-PCF) is an established approach for motion preservation, the outcomes are variable among patients. The objective of this study was to identify significant factors that influence motion preservation after MI-PCF. Methods : Forty-eight patients who had undergone MI-PCF between 2004 and 2012 on a total of 70 levels were studied. Cervical parameters measured using plain radiography included C2-7 plumb line, C2-7 Cobb angle, T1 slope, thoracic outlet angle, neck tilt, and disc height before and 24 months after surgery. The ratios of the remaining facet joints after MI-PCF were calculated postoperatively using computed tomography. Changes in the distance between interspinous processes (DISP) and the segmental angle (SA) before and after surgery were also measured. We determined successful motion preservation with changes in DISP of ${\leq}3mm$ and in SA of ${\leq}2^{\circ}$. Results : The differences in preoperative and postoperative DISP and SA after MI-PCF were $0.03{\pm}3.95mm$ and $0.34{\pm}4.46^{\circ}$, respectively, fulfilling the criteria for successful motion preservation. However, the appropriate level of motion preservation is achieved in cases in which changes in preoperative and postoperative DISP and SA motions are 55.7 and 57.1%, respectively. Based on preoperative and postoperative DISP, patients were divided into three groups, and the characteristics of each group were compared. Among these, the only statistically significant factor in motion preservation was preoperative disc height (Pearson's correlation coefficient=0.658, p<0.001). The optimal disc height for motion preservation in regard to DISP ranges from 4.18 to 7.08 mm. Conclusion : MI-PCF is a widely accepted approach for motion preservation, although desirable radiographic outcomes were only achieved in approximately half of the patients who had undergone the procedure. Since disc height appears to be a significant factor in motion preservation, surgeons should consider disc height before performing MI-PCF.

Purpose : The aim of this study was to identify the influence of transient isokinetic exercise on cardiac autonomic modulation and muscle properties in healthy male subjects. Methods : Twenty-eight healthy males underwent isokinetic exercise of both knee joints using a Biodex systems 3 isokinetic dynamometer with an angular velocity of 60 °/sec. The changes in activity of the autonomic nervous system, as determined by heart rate variability (HRV), and in muscle properties were evaluated at three times: pre-exercise, immediately post-exercise, and 10 min post-exercise. Results : The time domain analysis of HRV revealed significant changes in the beat count and mean and minimal heart rate (HR) measured at pre-exercise, immediately post-exercise, and 10 min post-exercise (p<.001). The beat count and mean HR were markedly increased immediately post-exercise compared to pre-exercise, but then significantly decreased at 10 min post-exercise (p<.001). All parameters of the frequency domain were significantly altered by isokinetic exercise (p<.01). The low frequency/high frequency (LF/HF) ratio, as an index for the sympathovagal balance, was elevated by exercise and remained at a similarly high level at 10 min post-exercise (p<.01). The muscle properties of rectus femoris were changed as follows: Muscle tone and stiffness were significantly increased between pre-exercise and immediately post-exercise (p<.001), and between pre-exercise and at 10 min post-exercise (p<.001). Whereas, the elasticity showed no significant change. Conclusion : These results demonstrated that transient isokinetic exercise could induce changes in cardiac autonomic control and muscle properties. In particular, up-regulation of LF/HF ratio after exercise signifies thus enhanced sympathetic modulation by isokinetic exercise. Therefore, it is needed to understand the cardiovascular risks that may arise during isokinetic exercise for providing the basic evidence to establish appropriate isokinetic exercise protocols as effective rehabilitation exercises.

Purpose: The Armed Forces Trauma Center of Korea was established in April 2022. This study was conducted to report our 1-year experience of treating soldiers with open fractures of the lower extremity. Methods: In this case series, we reviewed the medical records of 51 Korean soldiers with open fractures of the lower extremity between April 2022 and March 2023 at a trauma center. We analyzed patients with Gustilo-Anderson type II and III fractures and reported the duration of transportation, injury mechanisms, injured sites, and associated injuries. We also presented laboratory findings, surgery types, intensive care unit stays, hospital stays, rehabilitation results, and reasons for psychiatric consultation. Additionally, we described patients' mode of transport. Results: This study enrolled nine male patients who were between 21 and 26 years old. Six patients had type II and three had type III fractures. Transport from the accident scene to the emergency room ranged from 75 to 455 minutes, and from the emergency room to the operating room ranged from 35 to 200 minutes. Injury mechanisms included gunshot wounds, landmine explosions, grenade explosions, and entrapment by ship mooring ropes. One case had serious associated injuries (inhalation burn, open facial bone fractures, and hemopneumothorax). No cases with serious blood loss or coagulopathies were found, but most cases had a significant elevation of creatinine kinase. Two patients underwent vascular reconstruction, whereas four patients received flap surgery. After rehabilitation, six patients could walk, one patient could move their joints actively, and two patients performed active assistive movement. Eight patients were referred to the psychiatry department due to suicidal attempts and posttraumatic stress disorder. Conclusions: This study provides insights into how to improve treatment for patients with military trauma, as well as medical services such as the transport system, by revising treatment protocols and systematizing treatment.
Objective: The purpose of this study was to compare the lower extremity muscle activity and knee joint load according to movement speed conditions during the barbell back squat. Method: Nine males with resistance training experience participated in this study. Participants performed the barbell back squat in three conditions (Standard, Fast, and Slow) differing movement speed. During the barbell back squat, muscle activity of the rectus femoris (RF), vastus lateralis (VL), vastus medialis (VM), biceps femoris long head (BFL), semitendinosus (ST), gluteus maximus (GM), gastrocnemius (GCN), and tibialis anterior (TA) was collected using an 8 channel wireless EMG system. The peak flexion angle of the lower extremity joints and the peak resultant joint force in each direction of the knee joint were calculated using eight motion capture cameras and ground reaction force plates. This study was to used the Friedman test and the Wilcoxon signed rank test, to compare lower extremity muscle activity and peak resultant joint force at knee joint according to movement speed conditions during the barbell back squat, and the statistical significance level was set at .01. Results: In the downward phase of the barbell back squat, the RF and TA showed the higher muscle activity in the fast condition, and in the upward phase, RF, VL, VM, BFL, ST, GM, and TA showed the higher muscle activity in the fast condition. As a results, analyzing of the load on the knee joint, in the downward phase, and in the upward phase, the higher peak compressive force of the knee joint was showed in the fast condition. Conclusion: The barbell back squat with fast movement speed was more effective due to increased muscle activity of lower extremity, but one must be careful of knee joint injuries because the load on the knee joint may increase during the barbell back squat with fast movement speed.

Purpose : Repetitive bleeding into the joint space is the cause of debilitative hemophilic arthropathy. To interrupt this process, we treated the hemophilic patients suffering from repetitive joint bleeding with radiation therapy. Materials and Methods : From 1997 to 2001, a total of 41 joints from 37 hemophilic arthropathy patients were treated with radiation therapy at Kyung Hee University Hospital. The treated joints were 35 ankles, 3 knees and 3 elbows, respectively. The age of the patients ranged from 4 to 27 years (median age: 11 years). The radiation dose ranged from 900 cGy to 2360 cGy (median dose: 900cGy). The fraction size was 150 cGy, 180 cGy or 200 cGy. The number of bleeding in one year before and after radiotherapy was compared. Results : There was a tendency of frequent bleeding for the Patients younger than 11 (p=0.051) but there was also a tendency for more improvement in this group (p=0.057). The number of joint bleedings was related with joint pain (p=0.012) and joint swelling (p=0.033) but not with the Arbold-Hilgartner stage (p=0.739), cartilage destruction (p=0.718) and synovial hypertrophy (p=0.079). The number of bleeding was reduced in thirty-three cases, and eight cases showed no improvement after radiation therapy. The average number of bleeding in a month was 2.52 before radiotherapy, but this was reduced to 1.4 after radiotherapy (p=0.017). Conclusion : Radiation therapy was effective for the hemophilia patients with repetitive joint bleeding to decrease the bleeding frequency and to prevent hemophilic arthropathy.
Objectives The objective of this study is to investigate the application of Sifeng point (EX-UE 10) in children and to make suggestions for domestic research and clinical application by reviewing relevant randomized controlled trials. Methods Eight electronic databases including English, Chinese, Korean databases were comprehensively searched for randomized controlled trials evaluating the effects of Sifeng point in children up to May 2, 2018. We extracted the year of publication, country, target diseases or symptoms, location of Sifeng, acupuncture method; such as acupuncture tool and depth of insertion, and frequency, number, and duration of the treatment. Results Fifty studies were included for analysis. All the included studies were conducted in China, and studies were published from 1962 to 2017. The most frequent target symptom was anorexia (46%). In addition, Sifeng point was used for digestive diseases or symptoms such as diarrhea, constipation, and mesenteric lymphadenitis, as well as respiratory diseases or symptoms such as cough, cold, acute bronchiolitis, recurrent respiratory tract infections, bronchopneumonia, and asthmatic bronchitis. Also, allergic diseases such as chronic urticaria, and other variety of symptoms such as malnutrition, fever, and iron-deficiency anemia were treated with the Sifeng point. The location of Sifeng points was inconsistent, and the most common location of the Sifeng point was the midpoint of transverse creases of the proximal interphalangeal joints of the index, middle, ring and little fingers (84.2%). The most commonly used acupuncture tool was three-edged needle (40.9%). All included studies have the method of squeezing out blood or mucus from the Sifeng points. The treatment was mostly conducted once per week (35.4%), mostly repeated for 4 times (32.6%). The most common treatment duration was 4 weeks (18.6%). Conclusions We could identify acupuncture method and various indications for the Sifeng points treatment. Based on this study, there is a need for the clinical application and related researches on the Sifeng points in children in Korea. In addition, the treatment location of Sifeng point should be standardized.
This study was undertaken to find out the causal perception of rheumatoid arthritis patients, and to understand the typology. The Q-population consisted of 236 statements of causal perception were collected. Thirty eight Q-samples of causal perception were selected. The P-sample for this study were made up of 28 first visiting female rheumatoid arthritis patients from a rheumatoid arthritis specialty hospital. Each respondent responded Q-set of causal perception according to 9-point scale. The result of Q-sorting were coded and analyzed using QUANL PC program. 1) Typological Observation on Causal Perception (1) Physical Fatigue Type : Type 1 perceived that the illness occurred due to excessive work requiring physical labor or strain that had occurred from not resting after excessive physical labor, therefore, thinking the origin of the illness was from physical strain. (2) Physical origin Type : Type 2 perceived that the major cause for the illness is not only excessive physical labour but also fecundity and old age. (3) Causality to Environment Type : Type 3 perceived that rheumatoid arthritis occurred from injury to the joints or bad and humid weather. (4) Conscience of Guilty Type : Type 4 consisted of people with guilty conscience for lack of religious commitment. They perceived that the illness was a punishment from God for not praying or because of bad luck. (5) Rationally Perceiving Type : People who belong in type 5 perceived the cause of illness in light of scientific facts such as genetics, unbalanced diet or lack of exercise. (6) Psychological Stress Type : People who belong in type 6 believed that excessive stress was the cause of the illness. 2) Emotions of Rheumatoid arthritis patients Rheumatoid arthritis patients' positive emotions included determination, courage, coping, acceptance, hope, and adoption ; and their negative emotions were prostration, worry, stupor, conflicts, grievance, giving-up, resignation, depression, loss, solitariness, fear, anxiety, avoidance, anger and loneliness. Rheumatoid arthritis patients experience different level of emotions from their suffering experience from the severe pains. Rheumatoid arthritis patients also experience negative emotions when they could not perform self-care and lose their self-esteem from painful suffering ; however, they regain positive emotions when they recover from pain with the use of drugs, physical therapy or exercise. Their emotional states are closely connected to level of and presence of pain.

Background: Nonunion of lateral humeral condyle fracture causes cubitus valgus deformity. Although corrective osteotomy or osteosynthesis can be considered, there are controversies regarding its treatment. To evaluate elbow joint biomechanics in non-united lateral humeral condyle fractures, we analyzed the motion of elbow joint and pseudo-joint via in vivo three-dimensional (3D) kinematics, using 3D images obtained by computed tomography (CT) scan. Methods: Eight non-united lateral humeral condyle fractures with cubitus valgus and 8 normal elbows were evaluated in this study. CT scan was performed at 3 different elbow positions (full flexion, $90^{\circ}$ flexion and full extension). With bone surface model, 3D elbow motion was reconstructed. We calculated the axis of rotation in both the normal and non-united joints, as well as the rotational movement of the ulno-humeral joint and pseudo-joint of non-united lateral condyle in 3D space from full extension to full flexion. Results: Ulno-humeral joint moved to the varus on the coronal plane during flexion, $25.45^{\circ}$ in the non-united cubitus valgus group and $-2.03^{\circ}$ in normal group, with statistically significant difference. Moreover, it moved to rotate externally on the axial plane $-26.75^{\circ}$ in the non-united cubitus valgus group and $-3.09^{\circ}$ in the normal group, with statistical significance. Movement of the pseudo-joint of fragment of lateral condyle showed irregular pattern. Conclusions: The non-united cubitus valgus group moved to the varus with external rotation during elbow flexion. The pseudo-joint showed a diverse and irregular motion. In vivo 3D motion analysis for the non-united cubitus valgus could be helpful to evaluate its kinematics.
Purpose: This study is to identify the effect of Ankle Joint Taping applied to patients with chronic hemiplegia on their gait velocity and joint angles. Methods: We randomly extracted a clinical sample from 30 patients with hemiplegia resulting from stroke and classified them into two groups of a control group including 15 patients offered a regular therapeutic exercise and a test group including 15 patients offered taping. We also conducted the comparative analysis and pretest of the affected ankle joint angles by the normal characteristics of all subjects, Time to up and go test (TUG), 3D movement analyzer before the intervention. We applied taping to a test group for eight hours a day, five days a week during two weeks and conducted the comparative analysis of the gait velocity and the affected ankle joint angles by a comparison between and within two groups of before and after the intervention by conducting a posttest after the intervention. The result is as followings. Results: It indicated that there was a significantly decreased time with the increased gait velocity that a test according to a result of comparing the gait velocity within two groups (p<0.05). It indicated that there was a significantly increased angle in a comparison within two groups of test that inversion angle of a control group according to a result of comparing the ankle joint angles by 3D movement analyzer within groups (p<0.05). Conclusion: We found that TUG will help patients walk independently because it met a test group's need in the change of the gait velocity between two groups by recording less than 14 seconds which is the standard of using assistive aids and also found that ankle joint taping will help the joints prevent their function change considering that a control group showed an increased inversion angle in the change of the ankle joint within two groups.
