Severe midfoot Charcot neuroarthropathy (CN) presents a significant surgical challenge because of extensive bone loss and poor bone quality. This report presents the outcome of a case treated with realignment arthrodesis using a superconstruct technique, supplemented by the postoperative use of denosumab. A patient with Eichenholtz Stage III CN (Brodsky Type 1 and 2) underwent a single-stage surgical reconstruction. Postoperatively, denosumab was administered to enhance bone stability. The 1-year and 1-month follow-up showed that the severe deformity had been successfully corrected to a stable, plantigrade foot, confirmed by radiographic and clinical evaluation.This case suggests that a combined surgical approach using a superconstruct with adjuvant denosumab can be an effective treatment for severe midfoot CN.

Minimally invasive surgery (MIS) for hallux valgus correction has become increasingly popular over the past decade as an alternative to traditional open osteotomy techniques. Following the limitations of first- and second-generation percutaneous techniques, third-generation MIS, characterized by percutaneous osteotomy with a Shannon burr and stable screw fixation, has shown improved reproducibility and clinical outcomes. This review summarizes the current concepts of third-generation and later MIS techniques for hallux valgus correction, focusing on the surgical principles, technical considerations, fixation strategies, and postoperative management. In addition, the clinical and radiographic outcomes of MIS are compared with conventional open osteotomies. The available evidence consistently shows that MIS provides comparable deformity correction, functional improvement, complication rates, and recurrence rates to those of open procedures, while offering advantages such as reduced early postoperative pain, smaller incisions, and faster recovery. Recent studies support expanding MIS indications to include severe hallux valgus deformities that can provide satisfactory correction and acceptable complication profiles when appropriate techniques and fixation methods are used. Despite the ongoing debates regarding the optimal osteotomy type, fixation strategy, and proximal correction in severe deformities, MIS has emerged as a safe and effective surgical option across a broad spectrum of hallux valgus severity. Continued refinement of the surgical techniques, broader application across a wide range of hallux valgus etiologies, and long-term outcome data will further define the role of MIS in hallux valgus surgery.

Background: Tibiotalocalcaneal (TTC) arthrodesis is a viable salvage option for failed total ankle arthroplasty (TAA), but it is typically a complex procedure associated with a high complication rate. This study analyzed outcomes of salvage TTC arthrodesis using a retrograde intramedullary (IM) nail without subtalar joint preparation after failed TAA. Methods: This study included 18 patients (18 ankles) who underwent TTC arthrodesis without subtalar joint preparation for failed TAA from July 2008 to March 2023 and were followed up for at least 2 years. Visual analog scale pain scores and Ankle Osteoarthritis Scale pain and disability scores were used to assess functional outcomes. Radiographic union, time to union, complications, and clinical success—defined as pain improvement without the need for revision surgery or amputation—were also evaluated. Results: The mean follow-up duration after TTC arthrodesis was 79.8 months (range, 26–199 months). Tibiotalar joint union was achieved in 13 ankles (72.2%) at a mean of 7.5 months after TTC arthrodesis. Subtalar joint union was achieved in 7 ankles (38.9%). All functional scores improved significantly from preoperatively to the last follow-up. The overall clinical success rate was 83.3% (15 ankles). Conclusions TTC arthrodesis using a retrograde IM nail without subtalar joint preparation produced favorable outcomes in patients with failed TAA. No complications associated with the subtalar joint were observed in any patient during follow-up. Therefore, TTC arthrodesis using a retrograde IM nail without subtalar joint preparation may be a considerable salvage option for failed TAA.

Purpose: Total ankle arthroplasty (TAA) is a surgical option for end-stage ankle arthritis, including that caused by rheumatoid arthritis (RA). However, concerns persist regarding postoperative complications associated with inflammatory responses and immunosuppression in patients with RA. This study evaluated clinical outcomes and prosthesis survivorship in RA patients who underwent TAA for painful ankle arthritis. Materials and Methods: Thirty-four consecutive TAAs performed in RA patients with a minimum follow-up of 2 years were included and reviewed retrospectively. The visual analog scale for pain, ankle osteoarthritis scale pain and disability subscores, and ankle range of motion were used to assess clinical outcomes. Prosthesis survivorship, reoperations, complications, and risk factors were also analyzed. Results: The mean follow-up duration was 95.5 months (range, 26–221 months). All clinical scores significantly improved from preoperative values to the final follow-up. Revision surgery was performed on 6 ankles (17.6%), and 1 ankle (2.9%) failed due to deep infection. No minor wound complications were observed. Kaplan–Meier survival analysis demonstrated prosthesis survivorship rates of 97.4% at both 5 and 10 years postoperatively, and revision-free survivorship rates of 81.5% at 5 years and 74.7% at 10 years.No individual factor was significantly associated with revision. Conclusion Mobile-bearing TAA resulted in favorable clinical outcomes and high prosthesis survivorship in RA patients. No disease-specific factor was associated with revision surgery. These findings support TAA as a viable surgical option for RA patients with painful end-stage ankle arthritis.

Hallux valgus (HV) accompanied by metatarsus adductus (MA) is a surgical challenge because of its anatomical characteristics, often presenting with a high hallux valgus angle (HVA) despite a low intermetatarsal angle (IMA). This case report describes a 66-year-old female who presented with a 15-year history of left foot pain and deformity. The radiographs revealed an HVA of 45.0° and a low IMA of 7.2°, consistent with concomitant MA. Instead of a traditional proximal osteotomy for severe HV, the patient underwent a minimally invasive transverse distal metatarsal osteotomy along with distal metatarsal minimally invasive osteotomies (DMMOs) of the lesser metatarsals. At the 2-year follow-up, the radiographs showed excellent correction (HVA 12.5°, IMA 1.0°). The patient was asymptomatic and reported high functional and cosmetic satisfaction. This case shows that a minimally invasive transverse distal metatarsal osteotomy, combined with adequate ancillary procedures, can achieve a successful correction even in complex, severe HV with MA.

Severe bone defects pose a clinical challenge in total ankle arthroplasty (TAA) and are frequently considered contraindicated. We introduce an innovative approach that utilizes a structural tibial cut autograft to address anterior distal tibia bone defects during TAA. This technique is a viable alternative to employing revision TAA systems or resorting to excessively high tibial cuts. Furthermore, it facilitates achieving favorable sagittal alignment and ensures adequate fixation strength of the tibial component.

Background: Atrial fibrillation (AF) is a prevalent cardiac arrhythmia associated with significant morbidity and mortality, posing a considerable burden on healthcare systems. In Republic of Korea, the prevalence and incidence of AF have increased in recent years. There have also been significant changes in the trends of antiarrhythmic drug (AAD) use and procedural treatments for AF. Objectives: This study aims to review the trends in AF treatment strategies in Republic of Korea, particularly focusing on the utilization of antiarrhythmic drugs and catheter ablation. Methods: The Korean National Health Insurance Service (K-NHIS) data were used to identify AF patients from 2013 to 2022. AAD usage and catheter ablation procedures were analyzed annually. AADs were classified into Class IC and III drugs. Trends in beta-blockers, calcium channel blockers, and digoxin prescriptions were also examined. The primary endpoint was the trend of AAD use and AF catheter ablation (AFCA) over 10 years. Results: In 2022, 940,063 patients had a prior diagnosis of AF. From 2013 to 2022, the use of AADs increased from 12.1 to 16.4% among prevalent AF patients. Beta-blockers were the most commonly prescribed rate control medication, while the use of calcium channel blockers and digoxin declined. The frequency of AFCA procedures also increased, from 0.5% of prevalent AF patients in 2013 to 0.7% in 2022. Younger patients, males, and those with lower CHA2DS2-VASc scores were more likely to receive AFCA. Regional variations in treatment patterns were observed, with Seoul exhibiting higher rates of procedural treatments and AAD prescriptions. Conclusions Over the past decade, there has been a significant increase in the use of AADs and AFCA procedures in Republic of Korea. These trends reflect recent advancements in AF management advocating a refined rhythm control strategy.

Background/Aims: Fexuprazan is a novel potassium-competitive acid blocker that could be of benefit to patients with gastric mucosal injury. The aim of this study was to assess the 2-week efficacy and safety of fexuprazan in patients with acute or chronic gastritis. Methods: In this study, 327 patients with acute or chronic gastritis who had one or more gastric erosions on endoscopy and subjective symptoms were randomized into three groups receiving fexuprazan 20 mg once a day (q.d.), fexuprazan 10 mg twice a day (b.i.d.), or placebo for 2 weeks. The posttreatment assessments were the primary endpoint (erosion improvement rate), secondary endpoints (cure rates of erosion and edema and improvement rates of redness, hemorrhage, and subjective symptoms), and drug-related adverse events. Results: Among the patients, 57.8% (59/102), 65.7% (67/102), and 40.6% (39/96) showed erosion improvement 2 weeks after receiving fexuprazan 20 mg q.d., fexuprazan 10 mg b.i.d., and placebo, respectively. Both fexuprazan 20 mg q.d. and 10 mg b.i.d. showed superior efficacy to the placebo (p=0.017 and p<0.001, respectively). Likewise, both fexuprazan 20 mg q.d. and 10 mg b.i.d. also showed higher erosion healing rates than the placebo (p=0.033 and p=0.010, respectively). No difference was noted in the edema healing rate and the improvement rates for redness, hemorrhage, and subjective symptoms between the fexuprazan and placebo groups.No significant difference was noted in the incidence of adverse drug reactions. Conclusions Fexuprazan 20 mg q.d. and 10 mg b.i.d. for 2 weeks showed therapeutic efficacy superior to that of placebo in patients with acute or chronic gastritis (ClinicalTrials.gov identifier NCT04341454).

The sociomedical environment is changing. In the traditional physician-patient relationship, the physician was authoritative and the patient was obedient. The contractual relationship featured patient consent to the physician’s decision. Today, the physician must explain fully the planned medical treatment, and any alternative, to the patient, who has the right to choose her treatment after considering the benefits and side-effects. The Korean Society of Gynecologic Oncology (KSGO) thus decided to standardize the surgical consent forms to meet the legal requirements of modern medicine, improve patient understanding of the surgical details, and protect medical staff from legal disputes. To determine the format and content, subcommittees for each cancer type collected and reviewed all relevant articles and the current consent forms of domestic medical institutions. After several meetings, 16 basic items to be included for each type of gynecologic cancer were selected. Also, to help patients understand the surgical details, figures were included. The revised forms were legally reviewed in terms of the appropriateness of the format and content. We also developed English versions to provide adequate information for foreign patients. We hope that these efforts will promote trust between patients and physicians, and contribute to effective treatment by laying a foundation of mutual respect.
