RESUMO

Background: Wagstaffe fracture constitutes an indirect injury to the AITFL and can precipitate syndesmotic instability. The prevailing fixation methods often involve the use of mini-screws or K-wires, with absorbable suture repair reserved for cases with small or comminuted fragments exhibiting instability. In this study, we devised a mini-plate fixation method capable of securing the fracture fragment irrespective of its size or condition. Methods: A retrospective chart review was conducted on patients who underwent surgery for ankle fractures between May 2022 and October 2023. The surgical technique involved direct fixation of the Wagstaffe fracture using mini-plate fixation. Radiologic evaluation was performed using postoperative CT images, and clinical outcomes were assessed using the OMAS and VAS. Results: Fourteen patients with an average age of 62.5 years were included. Most fractures were associated with the supination-external rotation type. The average preoperative OMAS significantly improved from 5.95 to 83.57 postoperatively. The average VAS score decreased from 7.95 preoperatively to 0.19 postoperatively. Conclusions: The mini-plate technique for Wagstaffe fractures exhibited dependable fixation strength, effective fracture reduction, a minimal complication rate, and judicious surgical procedure duration.

RESUMO

Purpose: Pharmacopuncture therapy (PPT) combines medicinal extracts with acupuncture and is widely used as an adjunct in clinical practice. This study assessed the safety and feasibility of PPT in addition to conventional Korean Medicine treatment (CKMT), including electroacupuncture, cupping and infra-red, for lumbar spinal stenosis (LSS). Patients and Methods: Forty patients diagnosed with LSS were randomly assigned to undergo PPT with CKMT (experimental group) or CKMT alone (control group) at a 1:1 ratio, receiving 10 sessions of each intervention over five weeks. The primary clinical outcome was measured using the 100-mm Visual Analog Scale (VAS) for buttock and leg pain five weeks post-treatment. Secondary outcomes included clinically important difference (CID), Zurich Claudication Questionnaire, self-reported walking capacity, Modified-Modified Schober test, EuroQol 5-dimension 5-level questionnaire, and the patient's global impression of change. The adverse events were assessed at each visit. The analysis of covariance was conducted to compare between two groups. Results: Intervention completion rates were 95% and 100% in the experimental and control groups, respectively. No statistically significant differences were found between groups regarding the primary outcome (adjusted mean difference: 8.0; 95% confidence interval: -1.4-17.4). The mean difference in the 100-mm VAS for low back pain at week 5 (adjusted mean difference: 12.9; 95% confidence interval: 2.4-23.4) and the proportion of patients who reached the minimum CID was higher in the experimental group than in the control group. However, no significant differences were observed with other secondary outcomes. One patient in the experimental group experienced a systemic skin rash that resolved the same day, whereas the adverse events in the other group were mild and transient. Conclusion: This trial demonstrated the feasibility of add-on effects and the safety of pharmacopuncture in patients with LSS. Further studies are warranted to evaluate the add-on effects of PPT in treating LSS. Trial Registration: Clinical Research Information Service (CRIS), KCT0007229; registered on April 26, 2022.

RESUMO

Extensor hallucis longus tendon injury is relatively rare and is principally caused by a laceration when a sharp object is dropped on the instep. Primary suturing is possible if the injury is acute, but if the tear is chronic, tendon contracture causes the space between the edges of the tear to widen, disrupting the end-to-end connection. In particular, a claw toe or checkrein foot deformity may develop over time due to adhesion of the lower leg tendons near the fracture site or scar. We report on a 44-year-old man who visited our outpatient clinic complaining of pain in the right foot and a hindered ability to extend his great toe. He had enjoyed playing soccer during his schooldays; since that time, the extension of that toe had become somewhat difficult. T2-weighted sagittal magnetic resonance imaging revealed that the continuity of the extensor hallucis longus tendon had been lost at the distal phalangeal base attachment site, and that the region of the proximal tendon was retracted to level of the middle shaft of the proximal phalanx. The findings allowed us to diagnose extensor hallucis longus tendon rupture accompanying osteoarthritic changes in the joint and soft tissues. We performed surgical tenorrhaphy and adhesiolysis. This is a rare case of extensor hallucis longus tendon rupture caused by minor trauma. Arthritis that developed at a young age caused the adhesions. If patients with foot and ankle arthritis show tendon adhesion at the arthritic site, tendon rupture can develop even after minor trauma or intense stretching.

RESUMO

Ankle syndesmosis is crucial to the integrity of the ankle joint and weight-bearing; an injury to this structure can lead to significant disability. The treatment methods for distal syndesmosis injuries are controversial. The representative treatment methods include transsyndesmotic screw fixation and suture-button fixation, and good results with suture tape augmentation have recently been reported. However, an augmentation using suture tape is only possible when the posterior inferior tibiofibular ligament (PITFL) is intact. This study describes the case of an unstable syndesmosis injury, accompanied by anterior inferior tibiofibular ligament (AITFL) and PITFL injuries, which were treated successfully using suture tape. A 39-year-old male patient sustained right ankle damage while skateboarding. His leg and ankle radiographs revealed a widening of the medial clear space, a posterior malleolus fracture, a reduced "syndesmosis overlap" compared with the contralateral side, and a proximal fibula fracture. The magnetic resonance imaging revealed ruptured deltoid ligaments, accompanied by AITFL, PITFL, and interosseous ligament injuries. A diagnosis of a Maisonneuve fracture with an unstable syndesmotic injury was made. The patient underwent an open syndesmotic joint reduction, along with an AITFL and PITFL augmentation. This anatomical reduction was confirmed using intraoperative arthroscopy and postoperative computed tomography (CT). An axial CT that was performed at the 6-month follow-up exam revealed a similar alignment of the syndesmosis between the injured and uninjured sides. There were no surgical complications and the patient did not complain of discomfort in his daily life. At the 12-month follow-up exam, a good clinical outcome was confirmed. As a treatment for unstable syndesmosis injury, ligament augmentation using suture tape shows satisfactory clinical outcomes and can be considered as a useful and reliable method for anatomical restoration and rapid rehabilitation.

RESUMO

Background: Recently, Korean Medicine treatment with pharmacopuncture therapy (PPT) has been increasingly used in clinical practice to improve symptoms in patients with lumbar spinal stenosis (LSS). The aim of this study is to evaluate the effectiveness and safety of PPT in addition to conventional Korean Medicine treatment (CKMT) for the treatment of patients with LSS, compared with CKMT alone. Methods: This study is designed as a pragmatic, randomized, two-armed, parallel, stratified (by sex), controlled pilot trial. Forty patients diagnosed with LSS will be randomly allocated to the PPT + CKMT group or the CKMT group. Patients in the two groups will receive treatment two times weekly for 5 weeks. The primary outcome will be the mean change in the 100-mm visual analog scale score from the baseline to the end of treatment (week 5). The secondary outcomes will include the clinically important difference, Zurich Claudication Questionnaire score, self-reported walking capacity, Modified-Modified Schober test, EuroQol 5-dimension 5-level questionnaire, and Patients' Global Impression of Change. Adverse events will be assessed at each visit. Discussion: The results of this study will provide meaningful data to evaluate the add-on effect and safety of PPT in the medical care of patients with LSS.

RESUMO

Lumbosacral radiculopathy (LR) is a musculoskeletal disorder or pain syndrome that is generally linked to the compression or irritation of the nerve root. There is a growing interest in the development of efficient acupuncture-based treatments for LR comparable to western medicine. Structured traditional Korean medical treatments including intensified acupuncture stimulus on the EX-B2 point using the G-shaped posture modified from the sitting posture were applied to four LR patients, and the outcomes were evaluated based on objective clinical endpoints including a numeric rating scale (NRS), the Oswestry disability index (ODI), the manual muscle test (MMT), neurological symptoms, and plantar photography. Patients showed improvements in NRS, ODI, MMT, and neurological symptoms without adverse effects during hospitalization and follow-up visits. Moreover, we observed substantial dissolvement of hyperkeratinization and parchedness of the soles of the feet, which was not reported previously. These four cases demonstrate the clinical usefulness of traditional medicine and the diagnostic applicability of plantar photography. However, further randomized controlled trials are required to confirm our findings.

RESUMO

Background and objectives: Most Koreans obtain medical information from the Internet. Despite the vast amount of information available, there is a possibility that patients acquire false information or are dissatisfied. Chronic ankle instability (CAI) is one of the most common sports injuries that develops after an ankle sprain. Although the information available on the Internet related to CAI has been evaluated in other countries, such studies have not been conducted in Korea. Materials and Methods: The key term "chronic ankle instability" was searched on the three most commonly used search engines in Korea. The top 150 website results were classified into university hospital, private hospital, commercial, non-commercial, and unspecified websites by a single investigator. The websites were rated according to the quality of information using the DISCERN instrument, accuracy score, and exhaustivity score. Results: Of the 150 websites, 96 were included in the analysis. University and private hospital websites had significantly higher DISCERN, accuracy, and exhaustivity scores compared to the other websites. Conclusions: Accurate medical information is essential for improving patient satisfaction and treatment outcomes. The quality of websites should be improved to provide high-quality medical information to patients, which can be facilitated by doctors.

RESUMO

INTRODUCTION: This study aims to assess the feasibility of acupuncture as an add-on intervention for patients with non-emergent acute musculoskeletal pain and primary headache in an emergency department (ED) setting. METHODS AND ANALYSIS: A total of 40 patients who present to the ED and are diagnosed to have acute non-specific neck pain, ankle sprain or primary headache will be recruited by ED physicians. An intravenous or intramuscular injection of analgesics will be provided as the initial standard pain control intervention for all patients. Patients who still have moderate to severe pain after the 30 min of initial standard ED management will be considered eligible. These patients will be allocated in equal proportions to acupuncture plus standard ED management or to standard ED management alone based on computer-generated random numbers concealed in opaque, sealed, sequentially numbered envelopes. A 30 min session of acupuncture treatment with manual and/or electrical stimulation will be provided by qualified Korean medicine doctors. All patients will receive additional ED management at the ED physician's discretion and based on each patient's response to the allocated intervention. The primary outcome will be pain reduction measured at discharge from the ED by an unblinded assessor. Adverse events in both groups will be documented. Other outcomes will include the patient-reported overall improvement, disability due to neck pain (only for neck-pain patients), the treatment response rate, the use of other healthcare resources and the patients' perceived effectiveness of the acupuncture treatment. A follow-up telephone interview will be conducted by a blinded assessor 72±12 h after ED discharge. ETHICS AND DISSEMINATION: Written informed consent will be obtained from all participants. The study has been approved by the Institutional Review Boards (IRBs). The results of this study will guide a full-scale randomised trial of acupuncture in an ED context. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov: NCT02013908.

RESUMO

OBJECTIVES: This study aims to investigate the possible differences in skin temperature and blood perfusion changes between single and triple moxibustion. DESIGN AND SETTING: Thirty healthy volunteers were randomly divided into two groups: a triple moxibustion group (n=15) received indirect moxibustion on CV12 for 30min and a single moxibustion group (n=15) for 10min. After 10min of bed rest, skin temperature and blood perfusion were measured by digital infrared thermal imaging and laser Doppler perfusion imaging eight times in total, pre-moxibustion and 0, 5, 10, 15, 20, 25 and 30min post moxibustion. MAIN OUTCOME MEASUREMENT: The changes in the skin temperature and blood perfusion in an area 5cm in diameter around CV12 at 0min post treatment compared to baseline was the main outcome measurement. RESULTS: The difference of changes in skin temperature and blood perfusion on CV12 between the two groups remained statistically significant for 30min in an area 5cm in diameter around CV12 and for 25min in a 15-cm-diameter area. No adverse events were reported. CONCLUSION: Triple moxibustion with large, indirect moxa appeared to induce greater increases in skin temperature and blood perfusion than single moxibustion.

RESUMO

OBJECTIVES: Lumbar spinal stenosis (LSS) negatively affects patients' quality of life. No systematic review evaluating the effects and safety of acupuncture for this population is available. We aimed to evaluate evidence indicating the effectiveness and safety of acupuncture for LSS. METHODS: We searched five English-language databases (EMBASE, MEDLINE, CENTRAL, CINAHL, and AMED) and one Chinese database (CAJ) for randomised controlled trials (RCTs) and non-randomised controlled clinical trials (CCTs) of needle acupuncture for LSS. CCTs were analyzed only in terms of safety and intervention-related information. RESULTS: Six RCTs (n=582) and six CCTs, which were all from China and reported in Chinese, were included. High or uncertain risk of bias and clinical heterogeneity due to different acupuncture techniques were observed. All RCTs compared different combinations or techniques of acupuncture. None of the included studies mentioned safety issues. Acupuncture combined with other interventions and/or with additional stimulation increased the number of improved patients compared with acupuncture alone or relatively simpler stimulation (n=582; relative risk, 1.16; 95% confidence interval 1.08-1.25). Pain intensity, overall symptoms, and functional outcomes related to LSS and quality of life showed significantly favourable improvement in the treatment group compared with the control group, which lasted for up to 6 months post-treatment. CONCLUSIONS: We found no conclusive evidence of the effectiveness and safety of acupuncture for LSS because of high or uncertain risk of bias and the limited generalisability of the included studies. Future trials using rigorous methodology, appropriate comparisons and clinically relevant outcomes should be conducted.

RESUMO

OBJECTIVE: This study aimed to identify the descriptive characteristics of patients with pain conditions who visited an academic medical centre for traditional Korean medicine (TKM). METHODS: This work was a retrospective review of the electronic medical records of patients who received at least one session of acupuncture for pain management from March 2010 to February 2012 in the Korean medical hospital of Pusan National University. Demographic characteristics and data on patient conditions, treatment interventions received and costs associated with acupuncture treatments were analysed. RESULTS: We identified a total of 2167 patients, including 2105 outpatients and 237 inpatients. The mean age (SD) of the patients was 52.0 (15.3) years, and approximately two-thirds of the patients were women (64.0%). The average number of acupuncture treatment sessions was 8.0 (6.6 for outpatients and 14.5 for inpatients). The most treated conditions were low back pain (30.5%), neck pain (23.9%) and shoulder pain (17.5%). Interventions included needle acupuncture with manual (52.6%) or electrical (47.4%) stimulation, herbal medicine (44.2%), cupping (21.2%) and moxibustion (3.5%). Over one-third of outpatients (33.5%) received at least six sessions of acupuncture. The median total cost of each outpatient and inpatient care per person was 169 604 and 1 001 707 Korean Won (approximately £98 and £577), respectively. CONCLUSIONS: Acupuncture was primarily used for the treatment of low back, neck and shoulder pain with a wide range of related interventions at an academic medical centre for traditional Korean medicine. These data reflect real clinical practice and should inform the design of future prospective clinical research of acupuncture.

RESUMO

A case is reported of unexplained unilateral thigh muscle atrophy and frequent falling with poor response to conventional conservative treatments in a patient with bipolar disorder who self-selected acupuncture treatment as a last resort. The patient experienced gradual improvements in lower extremity weakness and fewer falls during the 8-month treatment. No adverse event or aggravation of the bipolar disorder was observed. These outcomes suggest that acupuncture may be a feasible adjunct for reducing falling and restoring postural balances in patients with bipolar disorder.

RESUMO

OBJECTIVES: Patients with non-emergent and non-life threatening conditions often present to the emergency department (ED), which hinders the efficient utilisation of healthcare resources. Acupuncture has frequently been used for such common conditions, although not in the ED context. This study aimed to evaluate the current evidence for acupuncture treatment in the ED and to inform future randomised controlled trials (RCTs) for acupuncture in ED settings. METHODS: Four English databases (MEDLINE, EMBASE, CENTRAL and AMED) were systematically searched to identify studies that tested the effects of acupuncture in ED settings using the search terms of "acupuncture" and "emergency". Data extraction and the risk of bias assessments were performed by two independent reviewers. RESULTS: Of the 102 screened studies, two RCTs and two uncontrolled observational studies were deemed eligible. Sample sizes ranged from 42 to 100. The conditions treated included various musculoskeletal and non-musculoskeletal symptoms and showed substantial clinical heterogeneity. Acupuncture was delivered in conjunction with standard medical care with the goal of immediate pain alleviation; in one RCT, acupuncture resulted in a positive outcome, but it did not in the other. The risk of bias was generally high or unclear. Uncontrolled studies reported beneficial effects for acupuncture, although these studies were prone to bias. Two studies reported mild and transient adverse events associated with acupuncture. CONCLUSIONS: The current evidence is insufficient to make any recommendations concerning the use of acupuncture in the ED. The effectiveness and safety as well as the feasibility of acupuncture should be tested in future RCTs.

RESUMO

This study aimed to investigate the anti-inflammatory, anti-arthritic and immuno-regulatory effects of electro-acupuncture (EA) at ST36 on Collagen-induced arthritis (CIA) in mice. Male DBA/1J mice were divided into five groups: Normal, Control, NR (needle retention), EAI and EAII. All mice except those in the normal group were immunized with Collagen II for arthritis induction. Acupuncture needles were inserted into mice ST36 and electrical currents at a frequency of 2 Hz in a continuous rectangular wave form were conducted through the needles for 15 min, 3 times a week. EA treatments were administered for 5 weeks in the EAI group and for 9 weeks in the EAII group. The mice in the NR group were acupunctured in the same manner as the EA groups and the needles were retained for 15 min without electrical stimulation. CIA incidence analysis, ELISA, histological analysis and FACS analysis were performed to evaluate the effect of EA on CIA. EA at ST36 significantly reduced CIA incidence, IL-6, TNF-a, INF-gamma, collagen II antibody, IgG and IgM levels in CIA mice serum and prevented knee joint destruction. EA at ST36 also reduced CD69+/CD3e+ cells and CD11a+/CD19+ cells in CIA mice lymph nodes, and CD11b+/Gr1+ cells in CIA mice knee joints. The ratios of CD3e+ cells to CD19+ cells, and CD8+ cells to CD4+ cells were maintained closer to the normal range in the EA groups as compared with the control group or the NR group. EAII was more effective than EAI throughout all the measurements. The NR was effective as well, though less effective than EA. EA at ST36 may have an anti-inflammatory, anti-arthritic and immuno-regulatory effects on CIA in mice. The effectiveness is stronger when EA starts earlier and is applied longer. Needle retention without electrical stimulation may be effective on CIA as well, however less effective than EA. Electrical stimulation and acupoint ST36 may have synergistic effects on CIA.

RESUMO

This study was undertaken to determine the optimal decomposition conditions when 1,4-dioxane was degraded using either the AOPs (Advanced Oxidation Processes) or the BAC-TERRA microbial complex. The advanced oxidation was operated with H2O2, in the range 4.7 to 51 mM, under 254 nm (25 W lamp) illumination, while varying the reaction parameters, such as the air flow rate and reaction time. The greatest oxidation rate (96%) of 1,4-dioxane was achieved with H2O2 concentration of 17 mM after a 2-hr reaction. As a result of this reaction, organic acid intermediates were formed, such as acetic, propionic and butyric acids. Furthermore, the study revealed that suspended particles, i.e., bio-flocs, kaolin and pozzolan, in the reaction were able to have an impact on the extent of 1,4-dioxane decomposition. The decomposition of 1,4-dioxane in the presence of bio-flocs was significantly declined due to hindered UV penetration through the solution as a result of the consistent dispersion of bio-particles. In contrast, dosing with pozzolan decomposed up to 98.8% of the 1,4-dioxane after 2 hr of reaction. Two actual wastewaters, from polyester manufacturing, containing 1,4-dioxane in the range 370 to 450 mg/L were able to be oxidized by as high as 100% within 15 min with the introduction of 100:200 (mg/L) Fe(II):H202 under UV illumination. Aerobic biological decomposition, employing BAC-TERRA, was able to remove up to 90% of 1,4-dioxane after 15 days of incubation. In the meantime, the by-products (i.e., acetic, propionic and valeric acid) generated were similar to those formed during the AOPs investigation. According to kinetic studies, both photo-decomposition and biodegradation of 1,4-dioxane followed pseudo first-order reaction kinetics, with k = 5 x 10(-4) s(-1) and 2.38 x 10(-6) s(-1), respectively. It was concluded that 1,4-dioxane could be readily degraded by both AOPs and BAC-TERRA, and that the actual polyester wastewater containing 1,4-dioxane could be successfully decomposed under the conditions of photo-Fenton oxidation.

RESUMO

AIM: To investigate the hepatoprotective effect of manual acupuncture at Yanglingquan (GB34) on CCl4-induced chronic liver damage in rats. METHODS: Rats were injected intraperitoneally with CCl4 (1 mL/kg) and treated with manual acupuncture using reinforcing manipulation techniques at left GB34 (Yanglingquan) 3 times a week for 10 wk. A non-acupoint in left gluteal area was selected as a sham point. To estimate the hepatoprotective effect of manual acupuncture at GB34, measurement of liver index, biochemical assays including serum ALT, AST, ALP and total cholesterol, histological analysis and blood cell counts were conducted. RESULTS: Manual acupuncture at GB34 reduced the liver index, serum ALT, AST, ALP and total cholesterol levels as compared with the control group and the sham acupuncture group. It also increased and normalized the populations of WBC and lymphocytes. CONCLUSION: Manual acupuncture with reinforcing manipulation techniques at left GB34 reduces liver toxicity, protects liver function and liver tissue, and normalizes immune activity in CCl4-intoxicated rats.
