Background: Grip strength is a convenient method to measure muscle strength. Recently, relative handgrip strength (HGS) was recommended as a clinical predictor of metabolic health and disease, such as dyslipidemia, which is considered a risk factor for cardiovascular disease. The purpose of this study was to characterize the association between relative HGS and dyslipidemia. Methods: We included 6,027 adults (2,934 men, 3,093 women) aged 30–69 years who participated in the Korea National Health and Nutrition Examination Survey in 2014 and 2015. Relative HGS was obtained by dividing the HGS by body mass index. Complex sampling analysis was conducted to compare the general characteristics of participants according to the quartiles of relative HGS. Logistic regression analysis was used to examine the association between quartiles of relative HGS and dyslipidemia. Results: After adjustment for age, prevalence of diabetes mellitus, prevalence of hypertension, alcohol consumption, smoking status, exercise, income, and education level, relative HGS was inversely associated with dyslipidemia in both men and women. In multivariable logistic regression analysis, the odds ratios (95% confidence intervals) for dyslipidemia in quartiles 1, 2, and 3 relative to quartile 4 were 1.36 (1.00–1.83), 1.29 (0.98–1.70), 1.23 (0.95– 1.60) in men and 1.81 (1.30–2.50), 1.81 (1.32–2.47), 1.39 (1.07–1.81) in women, respectively. Conclusion Relative HGS was inversely associated with dyslipidemia risk in Korean adults. Muscle-strengthening exercise is recommended to enhance health outcomes.

Humeral shaft fracture sustaining arm wrestling is rare, but occurs intermittently. We treated 15 cases of humeral shaft spiral fractures occurred during arm wrestling for fun since 2007. Average age was 22.47±2.69 years, average body mass index was 22.67±2.06 kg/m2. There was no prominent tendency for the fractures to occur at a certain phase of the match. Fractured level and length of each case were measured in the plain radiographs and compared with those of previous reports. Eight cases (53.3%) had an associating medial butterfly fragment, and the time taken until the fracture occurred was longer than that of simple spiral fracture (15.62±9.03 seconds vs. 7.85±2.67 seconds, p=0.048). Fractures were distributed mid to distal one third of humerus, the length of fracture was 7.93±2.69 cm and involved 25.43%±8.24% of humeral length. All cases except one treated surgically using plate and screws and returned their full activities within postoperative 3 months. Although arm wrestling is a simple and joyful sport, participants should be aware of the risks of injury during arm wrestling, especially for the amateur players.

PURPOSE: Anatomical medial knee reconstruction is crucial to the recovery of the knee joint. Our purpose is to determine the location of femoral insertion of the superficial medial collateral ligament (sMCL) and posterior oblique ligament (POL) from the attachment site of the adductor magnus and medial gastrocnemius tendon with MRI results. MATERIALS AND METHODS: A total of 200 knee magnetic resonance imaging results were retrospectively measured. The boundary of femoral insertion of sMCL and POL was marked and measured on the sagittal image. The attachment site of the adductor magnus tendon and medial gastrocnemius tendon was identified. The lineal, anterior-posterior and proximal-distal distances were measured from the attachment site to the center of the femoral insertion of sMCL and POL. RESULTS: The average size of sMCL and POL was as follows—sMCL: length of 13.5±1.7 mm, width of 10.9±0.3 mm and POL: length of 9.4±1.3 mm, width of 6.1±0.5 mm. The lineal distances from the insertion of the adductor magnus tendon and medial gastrocnemius tendon to the center of the sMCL and POL were measured—distances to the sMCL: 17.1±3.8 mm, 15.9±3.2 mm; distances to the POL: 11.9±2.9 mm, 8.2±2.7 mm. CONCLUSION: This study will help determine the location of the femoral attachment site of sMCL and POL by identifying the attachment section of the adductor magnus tendon and medial gastrocnemius tendon. Moreover, this study will guide the reconstruction of sMCL and POL when palpation of the bony structures become difficult.

STUDY DESIGN: Retrospective study. OBJECTIVES: To compare the treatment outcomes of conservative treatment, early vertebroplasty (EVP), and delayed VP (DVP) of patients with osteoporotic compression fractures. SUMMARY OF LITERATURE REVIEW: VP is regarded as an effective treatment for osteoporotic compression fractures. Few studies have compared the outcomes of each of the following treatments: conservative treatment, EVP, and DVP. MATERIALS AND METHODS: A total of 202 patients who presented with thoracolumbar osteoporotic vertebral compression fractures between January 2008 and December 2013 were divided into three groups: group 1 (conservative treatment), group 2 (VP within three weeks), and group 3 (VP after three weeks). We compared the collapse rate and the visual analog scale (VAS) score immediately after the trauma and at the 1-week, 3-week, 6-week, and 1-year follow-ups. RESULTS: The three abovementioned groups consisted of 89 patients, 60 patients, and 53 patients, respectively. The bone mass density (BMD) score of group 1 was statistically significantly higher than that of the others (p<0.05). In group 2, the average VAS score was high immediately after the trauma and low at the 1-year follow-up. Only group 2 showed a significantly high vertebral compression rate immediately after the trauma (p<0.05). Although there were no statistically significant differences in the incidence between the adjacent and the non-adjacent vertebral compression fractures, more patients underwent additional VP in groups 2 and 3 (p=0.980). CONCLUSION: The treatment method of performing EVP seems to yield the best clinical outcomes for patients with osteoporotic compression fractures who exhibit a relatively low BMD, high collapse rate, and high VAS score. Conservative management is the treatment of choice for osteoporotic compression fracture patients with a relatively high BMD, low collapse rate, and low VAS score.

BACKGROUND: Vitamin-mineral supplements are the most popular dietary supplements in Korea. However, few studies have assessed the relationship between vitamin-mineral supplementation and associated factors among the Korean elderly. The purpose of this study was to assess the use of vitamin-mineral supplements among elderly in Korea as well as its association with sociodemographic factors, health-related behaviors, medical conditions, and nutrient intake. METHODS: This study was based on data from the Korean National Health and Nutrition Examination Survey, conducted by the Korean Ministry of Health and Welfare from 2008 to 2009. Data from 3,294 elderly men and women (65 years of age and older) were analyzed. Multivariable-weighted logistic regression model analysis was used to evaluate the association between vitamin-mineral supplement use and sociodemographic factors, health-related habits, and medical conditions. RESULTS: Vitamin-mineral supplementation was reported by 16.3% of the participants. The most common reason for using dietary supplements was recommendations from friends and acquaintances. Highly educated person, female participants had a greater likelihood of taking vitamin-mineral supplements. In addition, analysis of nutrient intake from food sources alone revealed a lower proportion of vitamin-mineral supplement users with nutrient intakes below the estimated average requirements for vitamin A, vitamin C, thiamine, riboflavin, niacin, calcium, iron, and phosphorus, compared to nonusers. However, vitamin-mineral supplementation was not associated with health-related behaviors or medical conditions. CONCLUSION: Highly educated person, elderly Korean women had a greater likelihood of using vitamin-mineral supplements. In addition, nutrient intakes from food sources alone were significantly higher among vitamin-mineral supplement users. Finally, vitamin-mineral supplementation may be an indicator of healthier diet in elderly Koreans.

Fatigue fracture of the pelvis is the form of fracture due to repetitive micro-stress accumulation, can be affected by a number of factors such as patient's nutritional status, biomechanics, social status and so on. Still there is no study about precise standard degree of external force that lead to stress fracture, but it may caused by compression force, traction force or complex force and others. Avulsion stress to ischial tuberosity or anterior superior iliac spine by attached muscle is known as the main factor for the avulsion fracture. This report will deal with 19 years old conscripted policeman who occurred ischial tuberosity avulsion fracture after training of 6-hour running for 5 days accompanying hip hyper-flexion motion. This reports aims to provide case study of stress fracture occurred after 5 days of exercise which is relatively short period who had no specific trauma history or pain.

PURPOSE: To assess the progression of clinical symptoms and disease course of calcific tendinitis in the hip region according to types of calcification. MATERIALS AND METHODS: Among patients with the hip pain, 28 patients (21 males and 7 females; mean age 51 years, range 32-74 years) showing calcified lesions in simple radiography without other possible sources of pain were analyzed retrospectively. Twelve patients displayed a symptom duration of less than three weeks (acute; average=1+/-0.9 week) and 16 displayed greater than three weeks (chronic; average=21.0+/-19.5 weeks). Lesions were classified as nodular (11, 39.3%), nodular-fragmented (13, 46.4%), or amorphous (4, 14.3%). Initial symptoms, progression of clinical features, radiological findings and prognosis were investigated and analyzed according to calcification type. RESULTS: In 15 patients (53.6%), lesions were located superior to the great trochanter. On average, the acute group was younger (44.58 vs. 55.44 years, P=0.006), suffered more (mean pain Numeric Rating Scale [NRS], 6.3 vs. 3.8; P<0.001), and recovered more (difference between initial and follow-up NRS, 5.1 vs. 2.63; <<0.001) than the chronic group. The mean length of initial lesions was longer in the acute group than the chronic group (15.8 vs. 9.1 mm, P=0.008). When compared to patients with distinctive margins (15, 53.6%), those with nondistinctive margins showed better improvement (difference between initial and follow-up NRS, 4.7 vs. 2.8; P=0.01) and more significant decrease in lesion size (difference between initial and follow-up length, 10.8 vs. 2.6 mm; P=0.003). CONCLUSION: Calcific tendinitis occurring in the hip area displayed a variety of characteristics. Although complaining of more severe pain in the initial phase, patients with acute pain or calcific lesions with nondistinctive margins showed better symptom improvement when compared to their counterparts.

STUDY DESIGN: Case report OBJECTIVES: To report a case of motor weakness caused by the increasing size of a sacroiliac joint cyst after spinal fusion. SUMMARY OF LITERATURE REVIEW: There have been no reports on the increased size of a sacroiliac joint cyst and motor weakness after spinal fusion. MATERIALS AND METHODS: A 63-year-old female was admitted with low back pain and right sciatica. Magnetic resonance imaging (MRI) findings showed the spinal canal narrowing at L4-5 and a cystic lesion on the right sacroiliac joint. After surgery, the symptoms were relieved. RESULTS: One month after the operation, motor function had worsened to grade 4. Follow-up MRI revealed an increase in the size of the cystic lesion. Selective nerve root blocks were performed. There was gradual improvement, and the motor grade reached grade 5 seven months after the operation. CONCLUSIONS: We recommend that surgeons evaluate the adjacent segmental lesion by MRI before performing spinal fusion.

Gout is characterized by recurrent attacks of arthralgia, and deposition of monosodium urate crystals in and around the joints of the extremities and soft tissues. Monosodium urate crystals are observed most frequently at the 1st metatarsophalangeal joint and usually presented in the ankle and wrist joint. However, no case of an intratendinous tophus in the patellar tendon has been reported in Korean literature. In this report, we found monosodium urate crystals in the patellar tendon on magnetic resonance imaging images and intratendinous tophus were visible to the naked eye by excision. We reported on the case of a patient who experienced an unusual intratendinous tophus in the patellar tendon.
