Purpose: This study compared the functional and cosmetic treatment outcomes of intramedullary nailing (IM nail) and minimally invasive plate osteosynthesis (MIPO) for distal tibia shaft fractures. Materials and Methods: Forty-eight patients with distal tibia shaft fractures (distal 1/3 of the diaphysis, AO/OTA [AO Foundation/ Orthopaedic Trauma Association]) 43 managed by an IM nail (n=30) or MIPO (n=18) who had minimum one-year follow-up were enrolled in this study. The radiological, functional, and cosmetic outcomes in the two groups were compared retrospectively. Results: All patients achieved bone union. The mean bone union time of the IM nail and MIPO groups was 18.5 and 22.6 weeks, respectively (p=0.078). One patient in the MIPO group showed posterior angulation and valgus deformity of more than five degrees. The mean American Orthopaedic Foot and Ankle Society (AOFAS) functional scores were similar: 83.3 in the IM nail group and 84.6 in the MIPO group (p=0.289). The most salient difference was the cosmetic result of the surgical scar. The length of the scars around the ankle in the IM nail group was significantly smaller than the MIPO group (2.6 cm vs. 10.6 cm; p=0.035). The patient satisfaction survey of surgical scars revealed a significantly higher satisfaction rate in the IM nail group than in the MIPO group (93% vs. 44%; p<0.001). Conclusion This study showed that both treatment methods for distal tibia shaft fractures have similar therapeutic efficacy regarding the radiological and functional outcomes. On the other hand, the IM nail technique showed superior cosmetic outcomes than the MIPO technique. IM nails may be more recommended in patients with high demand for cosmetic results.

Purpose: Although the prevalence of a discoid lateral meniscus is relatively rare, estimated at approximately 0.4% to 5.0% in the Western world, studies have shown that the incidence is significantly higher in Asia, particularly in South Korea and Japan, ranging from 10.5% to 16.6%. On the other hand, previous studies that reported the incidence of discoid lateral meniscus mainly relied on patients who underwent arthroscopic or open surgery. This study examined the incidence of discoid lateral meniscus using a magnetic resonance imaging-based diagnostic approach. Materials and Methods: This study conducted a retrospective review of the prevalence of discoid lateral meniscus in 10,810 male patients with knee pain who underwent magnetic resonance imaging at the author’s single institution between January 2013 and January 2023. The mean age of the patients was 42.55±15.93 years old (range: 12 to 82). The patient demographics, including age, were analyzed.The characteristics of the discoid lateral meniscus were also analyzed, including the subtype and presence of a combined lateral meniscus tear. Results: This study identified 1,025 patients (9.5%) with a discoid lateral meniscus, including 129 with the complete subtype, 893 with the incomplete subtype, and 3 with the Wrisberg-type subtype. Although there was no significant difference in prevalence between sexes, the highest diagnosis rate of discoid lateral meniscus was observed in the 41–60-year-old (10.1%) age group, which was statistically significant (p=0.025). Among the 164 patients with a concurrent lateral meniscus tear, the horizontal type (80 patients, 48.8%) was the most frequently observed. Conclusion While the incidence in the present study was slightly lower than that reported in previous arthroscopic-based studies, the findings still suggest a relatively high prevalence of discoid lateral meniscus in Korea compared to other countries. In contrast to earlier research that suggested a decline in incidence with age, this study found that the incidence of discoid lateral meniscus was highest among individuals aged 41–60 years.

BACKGROUND: To determine whether olecranon fractures have osteoporotic features such as age-dependent, low bone attenuation and low-energy trauma as a cause of injury. METHODS: Elbow computed tomography (CT) and medical record review were performed in 114 patients (53 males and 61 females) with acute olecranon fractures. The mean age was 57 years. Bone attenuation was measured on the central part of the olecranon on sagittal CT images avoiding the fracture, and on the distal humerus (distal metaphysis and medial and lateral condyles) on coronal CT images. We compared bone attenuation and causes of injury (high or low energy trauma) between younger (<50 years) and older (≥50 years) patients in each gender. Multiple regression analysis was performed to determine the effect of age and gender on bone attenuation. RESULTS: Mean bone attenuation in older male and female patients was significantly lower than in younger patients, except at the medial condyle in men. The proportion of low-energy trauma in older male patients was significantly higher than in younger male patients. In female patients, low-energy trauma was predominant in both younger and older patients. Age and female gender had significantly negative effects on bone attenuation. CONCLUSIONS: This study demonstrated that olecranon fractures have osteoporotic features, including age-dependent low bone attenuation and low-energy trauma as the predominant cause of injury. Our results suggest that osteoporosis evaluation should be considered for patients aged 50 years or more with olecranon fractures.

PURPOSE: To compare the clinical 3 months postoperative results of three different 1-piece aspheric intraocular lenses (IOLs): AcrySof IQ SN60WF (Alcon Laboratories, INC, Fort Worth, TX), TECNIS 1-piece ZCB00 (AMO Inc., Santa Ana, CA) and the newly developed enVista MX60 (Bausch & Lomb, Rochester, NY). METHODS: In a total of 62 eyes, 1 of the 3 1-piece aspheric IOLs, AcrySof IQ SN60WF, TECNIS 1-piece ZCB00 or enVista MX60 was implanted after cataract extraction. Best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), and spherical equivalent were assessed 3 months postoperatively. Total spherical aberration, high order aberration, and modulation transfer function were analyzed. RESULTS: There were no significant differences of UCVA, BCVA, the accuracy of postoperative refractive power, and modulation transfer function among the 3 IOLs. Higher order aberrations of the entire eye and internal optics showed almost no significant differences. CONCLUSIONS: The newly developed IOL, enVista MX60, showed equivalent clinical outcomes as both AcrySof IQ SN60WF and TECNIS 1-piece ZCB00.

OBJECTIVES: The demand for hospice has been increasing among patients with cancer. This study examined the current hospice referral scenario for terminally ill cancer patients and created a data form to collect hospice information and a modified health information exchange (HIE) form for a more efficient referral system for terminally ill cancer patients. METHODS: Surveys were conducted asking detailed information such as medical instruments and patient admission policies of hospices, and interviews were held to examine the current referral flow and any additional requirements. A task force team was organized to analyze the results of the interviews and surveys. RESULTS: Six hospices completed the survey, and 3 physicians, 2 nurses, and 2 hospital staff from a tertiary hospital were interviewed. Seven categories were defined as essential for establishing hospice data. Ten categories and 40 data items were newly suggested for the existing HIE document form. An implementation guide for the Consolidated Clinical Document Architecture developed by Health Level 7 (HL7 CCDA) was also proposed. It is an international standard for interoperability that provides a framework for the exchange, integration, sharing, and retrieval of electronic health information. Based on these changes, a hospice referral scenario for terminally ill cancer patients was designed. CONCLUSIONS: Our findings show potential improvements that can be made to the current hospice referral system for terminally ill cancer patients. To make the referral system useful in practice, governmental efforts and investments are needed.
