ABSTRACT
This paper reports a case of a patient aged 63 years who developed a delayed pneumothorax after thoracic paravertebral block (TPVB). TPVB is a non-invasive procedure that is known to be relatively safe. A 63-year-old female was admitted with back pain. TPVB T9–10 left was then performed. Two days after the procedure, she complained of dyspnea in the emergency room. X-ray showed a pneumothorax in her left side with partial left lung collapse. The pneumothorax was managed by surgical intervention, and an intercostal tube was inserted. The post-procedural X-ray showed a fully expanded lung. A chest tube was taken out after 72 hours. A delayed pneumothorax can occur after TPVB. Therefore, careful observation is required after this procedure.
ABSTRACT
Surgery using a nerve block began in the 19th century. Since then, various anesthesia and block methods have been developed for upperextremity surgery. Many tools and techniques are being developed to increase the success rate and reduce the side effects from the nerve block. Recently, a nerve stimulator or an ultrasound device was used for a nerve block. The author review and describe various approaches and techniques using ultrasound as a block for upper extremity surgery.
ABSTRACT
Purpose@#This study examined the effectiveness of tranexamic acid in reducing postoperative blood loss in total knee arthroplasty by comparing the methods of administration between an intravenous group, topical group, and non-tranexamic acid group. @*Materials and Methods@#This was a retrospective case series study of patients who underwent primary total knee arthroplasty from March 2017 to February 2019 performed by a single surgeon. The study population was divided into three groups according to the method of tranexamic acid administration (Group I: intravenous group, Group II: topical group, Group III: non-tranexamic acid group). To evaluate the effectiveness of tranexamic acids, the total amount of postoperative blood loss, postoperative hemoglobin loss, and volume of red blood cell transfusion in the three groups were compared. @*Results@#The total amount of postoperative blood loss was lower in the tranexamic acid administered group than in the non-tranexamic acid group (1,366±866 ml). Among the administration methods, the intravenous group (987±449 ml) was significantly lower than the topical group (1,136±339 ml) (p=0.004). Postoperative hemoglobin loss was lower in the tranexamic acid group than the non-tranexamic acid group.Among the administration methods, the intravenous group was lower than the topical group. The transfusion rate was higher in the nontranexamic acid group (5.7%) than the tranexamic administered group. The transfusion rate of the intravenous group was 1.4%, and no patient required a transfusion postoperatively in the topical group. The number of postoperative thromboembolic events, as a complication of tranexamic acid, was similar in the three groups. @*Conclusion@#Tranexamic acid was effective in reducing postoperative blood loss after primary total knee arthroplasty compared to the nontranexamic acid administered group. No significant difference in the complications induced by tranexamic acid was observed among the three groups.
ABSTRACT
Purpose@#Intertrochanteric fractures can be treated using proximal femoral nail antirotation (PFNA). This study examined the clinical and radiological results of the intraoperative fracture compression. @*Materials and Methods@#Ninety-four patients underwent intraoperative compression (Group I), and 88patients underwent natural sliding only (Group II). The patients were followed-up for more than two years. All patients met the following seven conditions: (1) AO/OTA 31-A1, A2 type intertrochanter fracture, (2) availability of compression of more than one cortical bone in the anterior or medial regionof the fracture site under the preoperative imaging test, (3) Singh index grade ≥3, (4) blade position: center-center, center-inferior, (5) tip-apex distance <25 mm, (6) reduction status of good or very good, and (7) positive or neutral medial cortical support position with slightly valgus reduction. @*Results@#A slight tendency toward significant differences in acute phase pain between the two groups was observed at six weeks postoperatively (p=0.073). Twenty-four months after surgery, lateral extension of the PFNA helical blade between the two groups showed significant differences (p=0.017). Fracture gaps measured immediately after surgery showed significant differences (p=0.001), and a clear tendency for a significant difference in the average fracture union time was found (p=0.065). @*Conclusion@#Intraoperative fracture compression, intraoperative fracture compression appears beneficial to achieve a successful union of trochanteric fractures provided that all conditions are met to apply the method safely.
ABSTRACT
Function and strength of the deltoid muscle are important in reverse shoulder arthroplasty (RSA). Moreover, location and shape of the acromion, clavicle, and scapular spine, which are origins of the deltoid muscle, are also important. The frequency of os acromiale is 5% to 15%; however, it is rare in the Asian population, affecting approximately 0.7% of Koreans. RSA has rarely been reported in patients with os acromiale. We present a case series of two patients with cuff tear and arthropathy combined with os acromiale who underwent RSA. From 2016 to 2018, two patients with os acromiale who presented with pain and limited range of motion (ROM) underwent RSA with cuff tear arthropathy using the subscapularis-sparing deltopectoral approach. Their ROM, visual analog scale (VAS), and satisfaction were evaluated before and after surgery. In both patients, VAS decreased, ROM increased, and postoperative satisfaction increased. There were no specific complications due to os acromiale. The VAS, ROM, and satisfaction of patients improved after surgery compared with values before surgery. Thus, os acromiale is not a contraindication for RSA. However, careful attention must be given during surgery to ensure optimal repair and recovery.
ABSTRACT
OBJECTIVES@#The purpose of this study was to compare moderate-to-vigorous physical activity (MVPA) with walking in terms of associations with metabolic syndrome components in Korean older adults. @*METHODS@#Data on 1,388 older adults (age ≥65 years) from the Korea National Health and Nutrition Examination Survey 2018 were analyzed in this study. MVPA time and walking time per week were used as physical activity variables and blood pressure, waist circumference, glucose, high-density lipoprotein cholesterol, and triglyceride levels were analyzed as metabolic syndrome components. Partial correlations, analysis of covariance, and multinomial logistic regression were used for statistical analysis after adjusting for age, sex, smoking, and alcohol consumption. @*RESULTS@#High-density lipoprotein cholesterol levels were significantly higher in the low MVPA/high walking and high MVPA/ high walking groups than in the low MVPA/low walking group. Triglyceride levels were significantly lower in the high MVPA/ high walking group than in the low MVPA/low walking and low MVPA/high walking groups. Engaging in <150 min/wk of MVPA increased the likelihood of abnormal blood pressure and metabolic syndrome by 1.81 times and 1.89 times, respectively, compared to ≥150 min/wk of MVPA. Engaging in <180 min/wk of walking raised the likelihood of having abnormal highdensity lipoprotein levels by 1.32 times compared to ≥180 min/wk of walking. @*CONCLUSIONS@#Not only MVPA but also walking was significantly associated with metabolic syndrome components in Korean older adults. Considering older adults’ preferences and exercise barriers, walking should be considered as an essential component of physical activity guidelines to prevent chronic diseases in older adults.
ABSTRACT
Simple clavicle shaft fracture typically achieves satisfactory union after treatment and does not result in complication with conservative treatment. Non-union or malunion can occur in displaced clavicle fractures or comminuted shaft fractures. Treatment of displaced comminuted clavicle shaft fractures is performed by holding together the free fragments with interfragmentary screws or wires and fixing them to the clavicle with a plate. Therefore, we performed interfragmentary fixation using open reduction and internal fixation with bioresorbable screws (Mg-Ca alloy, Resomet Bioresorbable bone screw; U&I Corp.) and bioresorbable wires (Mg-Ca alloy, Resomet Bioresorbable K-wire and pin, U&I Corp.) for displaced comminuted clavicle fractures (Robinson type 2B) and additionally used a metal plate. We expected decreased irritation and infection due to absorption after surgery. We report four cases that were treated in this way.
ABSTRACT
In general, reverse shoulder arthroplasty revision is performed using the same implant for both the humerus and glenoid components. However, the authors of the present case used different implants from what was used previously for treating instability with scapular notching and glenoid aseptic loosening and report the case.

ABSTRACT
In reverse ball shoulder replacement, surgery is usually performed using a deltopectoral approach or an anterosuperior transdeltoid approach. The deltopectoral approach is to incise the pectoralis major to upper 1/3 to 1/2, and subscapularis tendon should be removed at the lesser tuberosity of the humerus. This approach has the problem of breaking the shoulder deltoid instead of incising the rotator cuff. Therefore, we report a detailed procedure of reverse ball shoulder replacement using approach without incision of the pectoralis major muscle and subscapularis muscle.

OBJECTIVES: This study investigated physical activity (PA) participation based on demographic, physical, and psychological variables in Korean adults.METHODS: Participants were divided into four groups (combined, aerobic only, resistance only, and neither) based on meeting the PA guidelines using moderate and vigorous PA time and resistance exercise frequency from the Korea National Health and Nutrition Examination Survey 2017. The association between meeting the PA guidelines and demographic, medical, fitness, lifestyle, and psychological variables were analyzed using complex samples crosstabs and a general linear model.RESULTS: Of the 5,820 Korean adults, 66.0% did not meet any of the guidelines. Among demographic factors, sex, age, marital status, income, education level, occupation, and employment status were associated with meeting the PA guidelines. Chronic disease prevalence, weight, waist circumference, body mass index, diastolic blood pressure, glucose, high-density lipoprotein and triglyceride levels, hand-grip strength, resting heart rate, and family history of chronic disease in the medical and fitness variables; frequency of drinking and eating breakfast, total calorie, water, protein, and fat intake in the lifestyle variables; and perceived stress, depression, suicidal thoughts, and quality of life in the psychological variables were associated with meeting PA guidelines.CONCLUSIONS: Most Korean adults participate in insufficient PA. Moreover, individuals who are socially underprivileged, have low-income or poor physical and mental health conditions participated in relatively less PA. Our findings suggest that government and individual efforts are required to increase PA and resolve health inequality in Korean adults.

ABSTRACT
Acute arterial occlusion is a rare complication following total knee arthroplasty (TKA). This is a report of a case of acute femoral artery occlusion and its sequelae following TKA in a patient with a history of atrial fibrillation. Arterial circulation of the lower limb could not be restored by thrombectomy treatments, and above-knee amputation had to be carried out.

Hallux valgus is a deformity that causes pain in the first metatarsophalangeal joint. Surgical methods are quite diverse and a range of osteotomies are used at the proximal and distal part of the metatarsal bone and proximal phalange. Fixation methods, such as plate, screw, K-wire, and others have been used in various ways. The fixation device is often removed with various side effects due to the fixation devices. In the case of instruments that are absorbed in vivo, these procedures are not necessary to remove and there is an advantage of not performing the second operation. Three patients were treated, in which a proximal chevron osteotomy was used with a bioabsorbable screw (K-MET™; U&I Corporation).

Enchondromas generally occur in the hand and uncommonly in the long bones. Because enchondromas are usually asymptomatic, most are discovered during diagnostic radiology for another disease. Here, we describe a case of enchondroma in the right humerus in a 79-year-old female patient with concomitant rotator cuff tear arthropathy. The patient was initially hospitalized for prolonged pain and pseudoparalysis of the right shoulder. The condition, which was histologically confirmed as an enchondroma in the proximal humerus, was treated with curettage and reverse total shoulder arthroplasty. In this case report, we present a rare case of an enchondroma with combined rotator cuff tear arthropathy.

Most radial head fractures occur as the result of low-energy mechanisms, such as a trip or fall on the outstretched hand. These fractures typically occur when an axial load is applied to the forearm, causing the radial head to hit the capitellum of the humerus. Good results are shown with nonsurgical treatments for Mason type 2 fractures. However, if there is a limitation of elbow joint exercise or displacement of more than 2 mm, an operative treatment should be considered. We treated two patients with arthroscopic assisted bioabsorbable screw (K-MET™; U&I Corporation, Uijeongbu, Korea) fixation for radial head fractures to prevent complications of open reduction and minimize radiation exposure.
