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.

Background: Skin and soft-tissue defects in the lower legs present significant challenges for surgeons, especially when tendons, bones, or implants are exposed. In such cases, simple dressings or skin grafts are insufficient, necessitating flap surgery.The bipedicled flap is a simpler and more reliable method with a high success rate compared to other flaps, showing minimal flap failures. This study aimed to examine the advantages and limitations of using a bipedicled flap for soft-tissue reconstruction in the lower legs. Methods: This retrospective study reviewed medical records from January 2013 to May 2020, involving 10 bipedicled flaps performed on the lower legs. The study included 5 male and 5 female patients, with an average age of 54.5 years. The defects were due to various causes, including trauma, tumor surgery, postoperative complications such as dehiscence and skin necrosis, and chronic osteomyelitis. The size of the defects ranged from 4 × 3 cm to 16 × 13 cm. The outcomes assessed included flap viability, postoperative complications, and patient satisfaction. Patient satisfaction was assessed on a 15-point scale, evaluating appearance, function, and sensation with up to 5 points each, and categorizing scores as poor (1–3), below average (4–6), average (7–9), good (10–12), and excellent (13–15). Results: All flaps were successfully performed, and there were no cases showing any special complications. Patient satisfaction following the operation was excellent in 3 patients, good in 6 patients, and average in 1 patient, with an overall average score of 11.5 (good) out of 15 among the 10 patients evaluated. Conclusions The bipedicled flap is a simple and secure method for treating soft-tissue defects in the lower legs. Therefore, this technique can be considered as one of the viable options for treating such defects.

Deep learning has recently achieved remarkable results in the field of medical imaging. However, as a deep learning network becomes deeper to improve its performance, it becomes more difficult to interpret the processes within. This can especially be a critical problem in medical fields where diagnostic decisions are directly related to a patient's survival. In order to solve this, explainable artificial intelligence techniques are being widely studied, and an attention mechanism was developed as part of this approach. In this paper, attention techniques are divided into two types: post hoc attention, which aims to analyze a network that has already been trained, and trainable attention, which further improves network performance. Detailed comparisons of each method, examples of applications in medical imaging, and future perspectives will be covered.

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.

PURPOSE: Patients with brain damage suffer from limitations in performing the activities of daily living (ADL) because of their motor function and visual perception impairment. The aim of this study was to help improve the motor function and visual perception ability of patients with brain damage by providing them with virtual reality-based contents. The usability results of the patients and specialists group were also evaluated. METHODS: The ADL contents consisted of living room, kitchen, veranda, and convenience store, similar to a real home environment, and these were organized by a rehabilitation specialist (e.g., neurologist, physiotherapist, and occupational therapist). The contents consisted of tasks, such as turning on the living room lights, organizing the drawers, organizing the kitchen, watering the plants on the veranda, and buying products at convenience stores. To evaluate the usability of the virtual reality-based visual cognitive rehabilitation service, general elderly subjects (n=11), stroke patients (n=7), stroke patients with visual impairment (n=4), and rehabilitation specialists (n=11) were selected. The questionnaires were distributed to the subjects who were using the service, and the subjective satisfaction of individual users was obtained as data. The data were analyzed using SPSS 21.0 software. The general characteristics of the users and the evaluation scores of the experts were analyzed using descriptive statistics. RESULTS: The usability test result of this study showed that the mean value of the questionnaire related to content understanding and difficulty was high, between 4–5 points. CONCLUSION: The virtual reality rehabilitation service of this study is an efficient service that can improve the function, interest, and motivation of stroke patients.

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.
