3D Morphometric Analysis of Femoral Isthmus Dimensions and Their Influence on Modular Kinked Revision Stem Design in Total Hip Arthroplasty.

The development of stems for femoral revision surgeries requires an understanding of how distal fixation can be achieved, especially in those cases where the curvature of the diaphysis is not negligible, and a straight stem could result in three-point fixation. To this extent, a series of parameters linked to the femoral canal isthmus were identified and their correlation, as well as the potential difference between White and Asian ethnicities, were investigated. The anatomical features of 215 three-dimensional femur models were automatically computed.

Risk of fragility fracture of pelvis in endometrial cancer survivors : A national claim database study.

Unlabelled: This study investigates the incidence and risk factors of pelvic fragility fractures in endometrial cancer survivors using a national claims database. The incidence was 0.6%, with older age as a significant risk factor.

Epidemiology of Femoroacetabular Impingement in Korea.

Background: Femoroacetabular impingement (FAI) is increasingly recognized as a significant cause of hip and groin pain. Despite the rising awareness, epidemiological data on FAI remain limited in East Asia. This study aimed to investigate the prevalence, treatment patterns, and associated medical costs of FAI in South Korea.

The Epidemiology of Osteonecrosis of the Femoral Head in South Korea: An Update in the COVID-19 Era.

Background: Osteonecrosis of the femoral head (ONFH) presents significant clinical challenges and variations in epidemiology across regions, with particularly high prevalence in East Asia. This study updates the trends in prevalence and associated medical costs of ONFH in South Korea from 2013 to 2022, with a focus on the impact of the COVID-19 pandemic.

Methods: We analyzed data from the Health Insurance Review and Assessment database, identifying patients diagnosed with ONFH using specific International Classification of Diseases, 10th revision codes.

Effect of Severe Bowing in Bisphosphonate-Related Atypical Femoral Fracture.

Backgroud: Long-term use of bisphosphonate is a risk factor for atypical femoral fractures (AFFs). Femoral bowing is known to be associated with AFFs. However, whether femoral bowing quickens the occurrence of AFF is unknown.

Prediction of 5-Year Survival Rate After Hip Fracture Surgery Using a Comprehensive Geriatric Assessment-Based Frailty Score Model.

Background: Hip fractures (HFs) are major osteoporotic injuries associated with morbidity, loss of independence, increased mortality, and an increased socioeconomic burden. The total number of HFs is increasing owing to an aging population. While studies have focused on 30-day or 1-year mortality after HF surgery, studies reporting long-term mortality are lacking.

Epidemiology of osteoporotic ankle fractures in South Korea: a nationwide retrospective cohort study (2006-2022).

Purpose: Ankle fractures, ranking as one of the very common osteoporotic fractures, pose a substantial socioeconomic burden. We aimed to investigate the incidence of elderly ankle fractures, refracture risks, and mortality rates in South Korea.

Methods: Utilizing the Korean National Health Insurance Service (NHIS) registry from January 2006 to December 2022, individuals over 50 years with ankle fractures were identified.

Causes of Reoperations After Primary Total Hip Arthroplasty: A Retrospective Cohort Study Over 20 Years.

Background: Reoperations following total hip arthroplasty (THA) remain a major clinical challenge, with their incidence and socioeconomic burden rising despite advances in surgical techniques and prosthesis design. This study aimed to evaluate the predominant causes of reoperations following THA over two decades at a tertiary referral hospital, comparing trends between 2004 to 2013 and 2014 to 2023.

Methods: We analyzed all reoperations performed at a tertiary referral hospital between January 2004 and December 2023.

Deep learning based screening model for hip diseases on plain radiographs.

Introduction: The interpretation of plain hip radiographs can vary widely among physicians. This study aimed to develop and validate a deep learning-based screening model for distinguishing normal hips from severe hip diseases on plain radiographs.

Methods: Electronic medical records and plain radiograph from 2004 to 2012 were used to construct two patient groups: the hip disease group (those who underwent total hip arthroplasty) and normal group.

Epidemiology of Paget's disease of bone in South Korea.

Paget's disease of bone (PDB) is a chronic disorder characterized by abnormal bone remodeling, leading to enlarged and deformed bones, and commonly affecting older adults. The disease frequently involves the pelvis, skull, spine, and long bones. Despite significant geographical variations in PDB prevalence, data from Asian populations remain sparse.

Deep learning for automated hip fracture detection and classification : achieving superior accuracy.

Aims: The aim of this study was to develop and evaluate a deep learning-based model for classification of hip fractures to enhance diagnostic accuracy.

Methods: A retrospective study used 5,168 hip anteroposterior radiographs, with 4,493 radiographs from two institutes (internal dataset) for training and 675 radiographs from another institute for validation. A convolutional neural network (CNN)-based classification model was trained on four types of hip fractures (Displaced, Valgus-impacted, Stable, and Unstable), using DAMO-YOLO for data processing and augmentation.
