Position Statement: Atypical Femoral Fracture from the Korean Society for Bone and Mineral Research in 2023.

As the aging population increases, the number of patients with osteoporosis is gradually rising. Osteoporosis is a metabolic bone disease characterized by low bone mass and the microarchitectural deterioration of bone tissue, resulting in reduced bone strength and an increased risk of low-energy or fragility fractures. Thus, the use of anti-resorptive agents, such as bisphosphonates (BPs), to prevent osteoporotic fractures is growing annually.

Bipolar Hemiarthroplasty in Unstable Intertrochanteric Fractures with an Effective Wiring Technique.

Purpose: Bipolar hemiarthroplasty has recently been acknowledged as an effective option for treatment of unstable intertrochanteric fracture. Trochanteric fragment nonunion can cause postoperative weakness of the abductor muscle and dislocation; therefore, reduction and fixation of the fragment is essential. The purpose of this study was to perform an evaluation and analysis of the outcomes of bipolar hemiarthroplasty using a useful wiring technique for management of unstable intertrochanteric fractures.

Midterm Outcomes of Intramedullary Fixation of Intertrochanteric Femoral Fractures Using Compression Hip Nails: Radiologic and Clinical Results.

The purpose of the present study was to evaluate the midterm outcomes of patients treated using compression hip nails (CHNs).

Fracture Liaison Service in Korea: 2022 Position Statement of the Korean Society for Bone and Mineral Research.

Osteoporosis and osteoporotic fractures cause socioeconomic concerns, and medical system and policies appear insufficient to prepare for these issues in Korea, where the older adult population is rapidly increasing. Many countries around the world are already responding to osteoporosis and osteoporotic fractures by adopting fracture liaison service (FLS), and such an attempt has only begun in Korea. In this article, we introduce the operation methods for institutions implementing FLS and characteristics of services, and activities of the FLS Committee for FLS implementation in the Korean Society for Bone and Mineral Research.

General versus Brachial Plexus Block Anesthesia in Pain Management after Internal Fixation in Patients with Distal Radius Fracture: A Randomized Controlled Trial.

Distal radius fractures (DRFs) are very common injuries associated with aging, and the number of fractures is increasing with the increase in the elderly population. General anesthesia or brachial plexus block (BPB) is required for fracture fixation, and acute postoperative pain control is necessary after operation. Early pain control can improve patient satisfaction and functional outcomes.

Transfusion Trends of Knee Arthroplasty in Korea: A Nationwide Study Using the Korean National Health Insurance Service Sample Data.

The purpose of this study was to evaluate trends of transfusion associated with knee arthroplasties using nationwide data of the National Health Insurance Service-National Sample Cohort (NHIS-NSC). Using data from the nationwide claims database of the Health Insurance Review Assessment Service managed by the NHIS, 50,553 knee arthroplasties under three categories (total knee replacement arthroplasty, uni-knee replacement arthroplasty, and revision arthroplasty) from 2012 to 2018 were identified.

Differential Diagnosis between Child Abuse and Infantile Cortical Hyperostosis: A Case Report and Literature Review.

Child abuse is a major public health problem that can lead to critical consequences for the child and family. However, early identification of abuse may be difficult. An 8-month-old boy presented with extensive periosteal reaction in both upper and lower long bones.

Hip Fracture Surgery without Transfusion in Patients with Hemoglobin Less Than 10 g/dL.

Backgroud: Hip fracture surgery is associated with blood loss, which may lead to adverse patient outcomes. The hemoglobin level declines gradually in most hip fracture cases involving femoral neck fractures and intertrochanteric fractures. It decreases further after hip fracture surgery due to perioperative bleeding.

Osteoporosis and Osteoporotic Fracture Fact Sheet in Korea.

Background: The socioeconomic burdens of osteoporosis and related fractures have increased in parallel with population aging. The Korea Society of Bone and Mineral Research published fact sheets on these topics in 2017, 2018, and 2019. This study provides complied epidemiological data based on these fact sheets for understanding current status of osteoporosis in Korea.

Pathologic mallet fracture of distal phalanx enchondroma: A case report.

Introduction: Enchondromas arise from cartilaginous cells derived from the physis that persists throughout development. They are difficult to diagnose and are often discovered on radiographs after a trauma.

Patient Concerns: We discuss the case of a 32-year-old woman with a pathologic mallet fracture of the distal phalanx that was initially misdiagnosed as common mallet fracture.

Reliability of measuring lateral bowing angle of the femur in patients with atypical femur fractures.

Background: Lateral femoral bowing causes a higher tensile mechanical load on the lateral side of the femur, which plays a critical role in the pathogenesis of atypical femoral fractures (AFFs). There are many ways to measure lateral femoral bowing on plain radiographs, and there are difficulties in finding a correspondence point between measurements among multiple measurers. The purpose of this study is to prove the best method of correspondence between the investigators by analyzing the reliability of various methods for measuring lateral femoral bowing.

Assessment of phase-lag entropy, a new measure of electroencephalographic signals, for propofol-induced sedation.
