This review focused on the research published to date on the treatment of phalangeal fractures according to the anatomical location of the finger bones, excluding the thumb. In many finger fracture cases, conservative treatment should be prioritized over surgical treatment. The three determinants of surgical treatment are the presence of an intra-articular fracture, the stability of the fracture itself, and the degree of damage to the surrounding soft tissues. Surgical treatment is recommended when bone fragments of 3 mm or more and distal phalanx subluxation are present in the bony mallet finger, and the main surgical treatment is closed reduction and extension block pin fixation. It is essential to pay attention to rotational deformation asf ractures occur proximally. Since intra-articular fractures can cause stiffness and arthritis in the future, a computed tomography scan is recommended to confirm the fracture pattern. These fractures require anatomical reduction of the bone fragments within the joint, and the instability of the joint itself must be corrected. There are no superior surgical treatment methods. It is therefore advantageous for the surgeon to select a surgical method that he is familiar with and confident of performing, considering the fracture itself and various patient-related clinical factors. Nonunion is rare as a complication of a finger fracture, and finger stiffness is the most common complication. Ensuring rapid joint movement as soon as possible can reduce finger stiffness.
2.Management of Elderly Patients with Chronic Kidney Disease
Yonsei Medical Journal 2025;66(2):63-74
Chronic kidney disease (CKD) is highly prevalent among elderly patients, and as the global population ages, the number of elderly patients with CKD is increasing. Elderly patients require additional considerations beyond those required for their younger counterparts, such as comorbidities, frailty, and geriatric syndromes. In this review, we primarily focus on these additional considerations specific to elderly patients and discuss the assessment of CKD and its management strategies, including blood pressure and glycemic control; dyslipidemia, anemia, and electrolyte and metabolic acidosis management; and medication dosage, among others, as well as polypharmacy and nonpharmacological management. Furthermore, the concept of conservative kidney management and the practical recommendations of the Korean Society of Geriatric Nephrology for elderly patients with end-stage kidney disease requiring dialysis therapy are discussed. In particular, the aging rate in Korea is exceptionally high; therefore, it is crucial to pay more attention to the increase in elderly patients with CKD. A more palliative approach, rather than intensive treatment strategies, may be necessary for these patients. In a world with an abundance of information, shared decision-making with patients is of great importance, and it is essential to keep in mind that this holds true for elderly patients as well.

We report on five cases of skin metastasis according to the breast cancer (BC) subtype. Two cases of HER2 positive BC showed only skin metastasis after immediate postoperative period and rapid clinical response to targeted therapy. Another two cases of triple negative BC showed thyroid and lung metastasis in addition to skin metastasis, and their response of cytotoxic chemotherapy was not definite. The other hormone positive BC showed skin metastasis only, with a longer, slower, less progressive pattern than other subtypes. Most cases of skin metastasis were detected at terminal stage of malignancy and were considered to have a limited survival period. However, some BC patients can survive longer if the targeted agents are effective. Therefore, physicians should provide detailed follow up of BC after curative treatment and understand the metastatic pattern of BC according to the subtype.

Cellulitis and deep vein thrombosis (DVT) have similar symptoms (lower extremity pain, erythema, and swelling) and there is the potential for misdiagnosis. In cases of cellulitis, DVT should be ruled out, as the symptoms of cellulitis might mask those of DVT, leading to serious complications such as pulmonary thromboembolism. The reported incidence of DVT in patients with cellulitis is low, especially patients with progression to pulmonary thromboembolism. We present a case of pulmonary thromboembolism following cellulitis of the lower leg in a 54-year-old male.

PURPOSE: The purpose of this study was to analyze the questions in the hip and pelvis section of the Korean Orthopaedic In-Training Examination (KOITE). MATERIALS AND METHODS: We analyzed all KOITE questions pertaining to hip and pelvis surgery between 2010 and 2014. A thorough analysis of the contents was performed after categorizing as tested topics, imaging modalities used, taxonomic classification, and recommended references. We also analyzed the scores of the hip and pelvis section of the KOITE. RESULTS: Seventy-five of five-hundred questions (weight, 15.0%) were related to the hip and pelvis. Trauma including fracture and dislocation (26/75, 34.7%) was asked more commonly than disease and basics. The description-only questions (65/75, 86.7%) were the most frequently asked. According to taxonomic classification, taxonomy 3 (decision; 39/75, 52.0%) was most frequently asked. Campbell's Operative Orthopedics (52/75, 69.3%) was the reference that covered most of the questions. CONCLUSION: This analysis of the hip and pelvis section of KOITE could be used for resident training programs in teaching hospitals.

BACKGROUND: It is difficult for surgeons to reconstruct soft tissue defects of the great toe. This report aims to evaluate the utility and efficacy of innervated distally based first dorsal metatarsal artery (FDMA) flap with a wide pedicle for reconstruction of soft tissue defects of the great toe. METHODS: This is a retrospective report. Between January 2015 and December 2017, six cases of skin defect of the great toe were reconstructed with an innervated distally based FDMA flap with a wide pedicle. One case was excluded in this report because of chronic pain on the metatarsophalangeal joint due to osteoarthritis before the injury. A total of five cases were evaluated for flap survival and sensory recovery. The sensory recovery was investigated by two-point discrimination and Semmes-Weinstein monofilament tests. The average age of the selected patients was 40 years (range, 36 to 56 years), and the average size of the defect in the toe was 8.3 cm2 (range, 4 to 13.8 cm2). The average follow-up period was 29.4 months (range, 18 to 38 months). RESULTS: All patients survived without any complications. The average two-point discrimination test value was 8.0 ± 0.89 mm (range, 7 to 9 mm), and the average value obtained from the Semmes-Weinstein monofilament test was 4.53 ± 0.33 (range, 4.17 to 4.93). The average residual pain score evaluated with a visual analog scale was 1 (range, 0 to 2). Two patients complained of stiffness in the great toe below 30° of total range of motion during the early stages after surgery, but this stiffness gradually improved after rehabilitation. The average range of motion of three patients with a remaining metatarsophalangeal joint after surgery was 80° (range, 70° to 90°). All five cases could walk regularly without any unique footwear at the final follow-up. CONCLUSIONS: The innervated distally based FDMA flap with a wide pedicle could be a good alternative method for repair of soft tissue defects of the great toe.
