A medial closing wedge supramalleolar osteotomy, along with corrections for pes plano-valgus, including medial displacement calcaneal osteotomy, and deltoid ligament repair or reconstruction, is most commonly considered for the joint-preserving surgery of valgus ankle arthritis. In cases of ‘opposing coronal plane deformities,’ however, where the tibial plafond is varus-aligned to the long axis of the tibia and the ground, while the talus is conversely valgus-aligned, medial closing wedge supramalleolar osteotomy may paradoxically risk exacerbating the valgus ankle arthritis. This paper reports the radiological and clinical outcomes of an otherwise healthy, physically active 55-year-old male patient with valgus ankle arthritis and opposing coronal-plane deformities, along with a literature review. The patient underwent joint-preserving surgery consisting of lateral closing wedge supramalleolar osteotomy, fibular osteotomy, medial displacement calcaneal osteotomy, and deltoid ligament augmentation with suture tape. This paper discusses the critical considerations and surgical precautions necessary when deciding on joint-preserving procedures for valgus ankle arthritis.

Medial opening wedge supramalleolar osteotomy (SMO) is a representative joint-preserving surgical procedure for varus ankle osteoarthritis, based on the principle of load redistribution, with favorable radiologic and clinical outcomes. This procedure is indicated for patients with Takakura stage 2 or 3A arthritis, whereas severe vascular or neurological impairment and osteomyelitis are considered absolute contraindications. Although SMO is generally limited to patients younger than 70 years because of the risk of delayed or nonunion in elderly individuals, few reports on the outcomes in elderly patients have been published. This paper reports two cases of varus ankle osteoarthritis in patients over 75 years of age who underwent SMO after failed conservative treatment, with a follow-up exceeding 2 years, along with a review of the relevant literature. Both cases achieved successful bone union without delayed healing. At the final follow-up, the foot and ankle ability measure (FAAM)–activities of daily living and FAAM-sport scores showed marked improvement compared with the preoperative values. In conclusion, SMO may be a viable joint-preserving treatment option, even in elderly patients, provided that their general health is favorable.

Purpose: Older cancer patients face unique challenges due to age-related physiological changes, increasing their vulnerability to treatment-related toxicities. Geriatric assessment (GA) is a validated tool for optimizing care, yet there is no consensus on integrating geriatric interventions into oncology. This study evaluates the feasibility of a tailored onco-geriatric intervention model incorporating the KG-7 screening tool. Materials and Methods: This prospective study included 30 patients aged ≥ 70 years with solid tumors undergoing adjuvant or palliative chemotherapy. Patients scoring ≤ 5 of KG-7 were eligible. Tailored interventions incorporating KG-7 included polypharmacy, functional status, mobility, nutrition, cognition, emotional well-being, insomnia, social support, and medical problem. KG-7, GA, and quality of life (QoL) were followed at 12 weeks. Results: Participants (median age, 79.5 years) had colon (43.3%), pancreatic (23.3%), or gastric cancer (23.3%). At baseline, most patients showed independent activities of daily living (100%)/instrumental activities of daily living (90%). However, 93.3% had abnormal GA. Particularly, 86.7% were either malnourished or at risk of malnutrition. The most frequently identified intervention needs included polypharmacy (70.0%), nutritional support (60.0%), and emotional well-being (50.0%) with high adherence (100.0%, 88.9%, and 46.7%, respectively). At 12 weeks, KG-7 scores improved in 43.8% of patients, and 69.2% of GA domains were improved. QoL analysis revealed modest improvement in Global Health Status (mean difference, 6.3; p=0.176). One-year survival rates were 92.3% and 79.4% for adjuvant and palliative groups, respectively. Conclusion The onco-geriatric intervention model incorporating KG-7 demonstrated high feasibility and potential to enhance clinical outcomes. Future studies should validate this approach in randomized trials to optimize care for older cancer patients.

Purpose: The male predominance in the incidence of gastric cancer (GC) is established; however, sex differences in the prognosis of GC remain controversial. As such, this study analyzed the prognosis of patients with GC based on age and sex. Materials and Methods: Data from 14,739 patients diagnosed with GC at Seoul National University Bundang Hospital between 2003 and 2023 were analyzed. Baseline characteristics, histological types of GC, overall and GC-specific survival rates (age and stage stratification), and associated risk factors were analyzed. Results: Females were significantly younger (p < 0.001) and exhibited more gastric body cancers (p < 0.001) and tumors with diffuse-type or poorly differentiated histology (p < 0.001) than males. Females exhibited an advantage over males in terms of overall survival (p=0.004), but not in GC-specific survival. However, age stratification revealed significant sex differences, that females < 50 years of age exhibited survival disadvantages (p < 0.001); however, this trend was reversed with age, and females > 60 years exhibited survival advantages (p < 0.001) for both overall and GC-specific survival. This may be explained by the lower ratio of diffuse-type GC as females age. Furthermore, in the analysis according to stage, females with stage IV disease exhibited significant survival disadvantages, with significantly younger age and a higher proportion of diffuse-type GC which exhibits aggressive features, resulting in poorer survival than in males. Conclusion Age and stage stratification revealed significant differences in survival between the sexes, which can be helpful for public health strategies.

Purpose: To develop the 2025 update to the Korean colorectal cancer (CRC) screening guidelines by systematically evaluating recent evidence, integrating domestic data, and addressing changes since the 2015 guideline revision, thereby providing an evidence-based standard for clinicians and policymakers. Methods: A multidisciplinary committee developed the guidelines using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. The process included formulation of three key questions addressing screening efficacy, diagnostic accuracy, and optimal screening age and interval. A systematic review of international guidelines and primary literature was conducted, yielding 327 eligible studies. In addition, a utility-based analysis using a Markov model was performed to determine optimal screening ages and intervals. Results: The evidence synthesis identified high-certainty evidence supporting the use of the fecal immunochemical test (FIT) for reducing CRC mortality and moderate-certainty evidence for colonoscopy. Evidence for computed tomographic colonography (CTC) and stool DNA testing was rated as very low certainty. Based on the evidence review and cost-utility analysis, the committee conditionally recommends CRC screening for asymptomatic, average-risk adults aged 45–74 years using either colonoscopy every 10 years or FIT every 1–2 years. CTC and stool DNA testing were not recommended owing to insufficient evidence. Conclusion The 2025 Korean Guidelines for Colorectal Cancer Screening present updated, evidence-based recommendations tailored to the domestic healthcare context. By conditionally endorsing both colonoscopy and FIT for individuals aged 45–74 years, these guidelines aim to improve population-level screening effectiveness and reduce the burden of CRC in South Korea.

Multidirectional joint instability is a condition where laxity occurs in two or more directions. This condition typically arises congenitally or because of hypermobility or repetitive, excessive physical activity. It can also occur from chronic damage to the joint capsule and multiple ligaments, causing a breakdown in stability. Despite the numerous studies conducted on multidirectional instability of the shoulder, there is a lack of published research on multidirectional instability of the ankle. This paper reports the case of a male patient in his early 30s, engaged in high-demand physical activity, who presented with simultaneous medial and lateral ankle instability. The patient underwent a combination of procedures, including an anterior talofibular ligament reconstruction with suture tape, deltoid ligament reattachment with suture anchors, anteroinferior tibiofibular ligament reconstruction with suture tape, and syndesmotic screw fixation with Tightrope insertion. The patient was followed up for one year postoperatively. This paper reports the clinical outcomes with a review of the relevant literature.

Background: Studies comparing the minimally invasive proximal chevron and Akin osteotomies (MIPCA) technique with conventional techniques, such as the open proximal chevron metatarsal osteotomy with the Akin procedure (open PCMO-Akin procedure), are limited. This study aimed to compare and evaluate operative MIPCA and open PCMO-Akin procedure outcomes in the surgical correction of moderate-to-severe hallux valgus deformities. Methods: We conducted a retrospective comparison of clinical and radiographic outcomes between the MIPCA and open PCMOAkin procedure in patients with a hallux valgus deformity, defined as a preoperative hallux valgus angle (HVA) of ≥ 30° and/or a first to second intermetatarsal angle of ≥ 13°. The postoperative complication rate was monitored in both groups for a minimum of 12 months. An unsatisfactory correction was defined as an HVA > 15° at final follow-up. Results: We assigned 58 and 99 patients to the MIPCA or open PCMO-Akin procedure group, respectively. At final follow-up, no significant differences were observed between the groups in terms of clinical and radiographic parameters (p > 0.05), with the exception of the distal metatarsal articular angle (DMAA) (p = 0.012). No statistically significant postoperative changes in the DMAA were observed in the MIPCA group (p = 0.875). Five patients (5.1%) experienced postoperative hallux varus in the open PCMO-Akin procedure group, whereas no such cases were observed in the MIPCA group. No statistically significant difference in the rate of unsatisfactory correction was observed between the groups at the final follow-up (MIPCA group, 15.5%; open PCMO-Akin procedure group, 10.1%; p = 0.315). Conclusions The MIPCA technique is a viable alternative to the open PCMO-Akin procedure for correcting moderate-to-severe hallux valgus deformities. Given the potential lack of postoperative changes in the DMAA following the MIPCA technique, careful consideration is advised when applying this technique to patients with a large DMAA.

Background and Objectives: Hearing loss significantly affects communication, psychosocial well-being, and quality of life. This study analyzes the National Health Insurance Service database to assess the trends and characteristics of hearing loss in South Korea from 2010 to 2020.Subjects and Method The database encompasses 97% of the Korean population, providing comprehensive data on medical history, prescriptions, and health examinations. The analysis used the World Health Organization’s ICD-10 definitions to categorize hearing loss types and examine their prevalence and incidence across various demographics over 11 years. Results: There was an overall annual increase of 4.62% in diagnosed cases of hearing loss, with the most significant rise among the elderly. The rate of increase accelerated from 3.32% between 2010 and 2014 to 6.49% between 2014 and 2020, corresponding with the improved hearing aid access facilitated by policy changes. Women showed a slightly higher increase than men. The data also indicated a consistent rise in abnormal hearing test results during health examinations, especially in older adults. Conclusion The study highlights an increasing trend in hearing loss diagnoses, driven by an aging population and enhanced detection facilitated by policy changes. These findings emphasize the need for continuous monitoring and targeted health policies to manage hearing loss effectively, offering valuable insights for global health management and policy development.

Background and Objectives: This study aims to analyze trends in hearing disability and the use of hearing rehabilitation devices (hearing aids and cochlear implants) in South Korea over the past 11 years (2010-2020) using data from the National Health Insurance Service (NHIS).Subjects and Method Data were extracted from the NHIS database, covering approximately 97% of the South Korean population. Patients diagnosed with hearing loss were classified using ICD-10 codes. The data were analyzed to determine trends in hearing disability, hearing aid prescriptions, and cochlear implant usage by age, gender, and types and causes of hearing loss. Results: The number of hearing disability patients increased from 170900 in 2010 to 362738 in 2020, with an annual growth rate of 7.95%. The highest increase was observed in the ≥60 age group, with an annual growth rate of 11.04%. Hearing aid prescriptions rose from 4966 in 2010 to 11974 in 2020, showing a 10.45% annual increase. Females showed a higher growth rate in both hearing disability and hearing aid prescriptions compared to males. Cochlear implant prescriptions also increased, particularly among older adults. Conclusion The study highlights a significant rise in hearing disability and the use of hearing aids and cochlear implants in South Korea, especially among the elderly. The findings underscore the importance of early diagnosis and intervention for hearing loss and the need for policy improvements to enhance accessibility and affordability of hearing rehabilitation services. Additional strategies are needed to ensure appropriate hearing rehabilitation for those not yet receiving adequate care.
