Dorsal articular collapse in distal radius fractures presents unique fixation challenges. While volar locking plating (VLP) dominates current practice, dorsal vertical double plating (DVDP) offers direct biomechanical support but carries perceived tendon risks. This study compares DVDP versus VLP for dorsally collapsed comminuted fractures.

To evaluate the surgical efficacy of repeated vertebral column resection (Re-VCR) after instrumentation removal in congenital scoliosis (CS) patients previously undergoing primary posterior spinal correction with VCR, and to analyze complications pertinent to revision surgery.

Hyperuricemia, characterized by elevated serum uric acid levels without acute gout symptoms, may influence postoperative outcomes after total knee arthroplasty (TKA). This study aimed to evaluate the impact of hyperuricemia on postoperative inflammatory responses, complications, and mid-term functional outcomes in patients undergoing primary TKA.

It is unclear whether a hip with a developmental dysplasia deformity can remain functional and free of osteoarthritis (OA) throughout life. This study aims to determine the percentage of Chinese older adults without severe OA who meet the diagnostic criteria for DDH and BDDH. Additionally, this study seeks to explore hip morphology in this population.

Total hip arthroplasty (THA) with Ceramic-on-Ceramic (CoC) components achieved excellent outcomes. However, the long-term outcomes of anatomic and tapered stems are controversial in clinical practice, and the difference in the survival rates between the tapered stems and anatomical stems over the long term remains unknown.

The etiology of adjacent segment diseases and proximal junctional kyphosis has been related to biomechanical alterations after spinal operation. This study investigated the variation in pre- and postoperative range of motion in adjacent segments in patients with degenerative lumbar scoliosis (DLS) following posterior lumbar interbody fusion.

This study provides one of the most extensive long-term follow-up analyses of unplanned revisions following 3CO for spinal deformities, with a mean follow-up duration of 9.8 years, which has been underexplored in prior research. The findings provide critical data for preoperative discussions with patients and their families regarding the risks of unplanned reoperation. Additionally, the study highlights the need for long-term surveillance and proactive strategies to mitigate revision risks, particularly in patients undergoing multilevel 3CO.

This scoping review summarizes the evidence regarding sociodemographic disparities in long-term ( 6 months postoperative) functional outcomes after total hip and knee arthroplasty (THA/TKA). Five databases were searched by a librarian. US-based original research articles that reported on long-term functional outcomes after THA/TKA by sex, race, ethnicity, socioeconomic status, and/or geography were included. Seventy-nine articles met inclusion criteria. Fifty-four articles reported on sex disparities, with 60% of post-THA and 51% of post-TKA outcomes finding that men had a better long-term functional outcome than women. Across the 34 articles and 72 outcomes that examined the variable of race or ethnicity, 63% of post-THA outcomes and 69% of post-TKA outcomes found White patients had better long-term function compared to minoritized patients. In the 24 articles and 47 outcomes that examined socioeconomic status (SES) in relation to long-term function, 63% of post-THA and 71% of post-TKA outcomes indicated higher SES was associated with better long-term function. Only 3 of the 79 studies looked at geography. None found significant disparities. The evidence from our sample shows that disparities in long-term functional outcomes post-THA/TKA likely exist for different racial, ethnic, and socioeconomic groups. There is a lack of data on smaller racial and ethnic minority populations, rural communities, and the way sociodemographic variables may interact with one another. Comparisons across studies were limited due to variation in the outcome measures used and length of follow-up. Additional research should identify patients at risk of decreased long-term function after THA/TKA and protocols to enhance their functional recovery.

Osteonecrosis of the femoral head (ONFH) is a progressive and disabling disease that commonly affects young and middle-aged adults. Without timely treatment, it often progresses to femoral head collapse and hip dysfunction, ultimately requiring total hip arthroplasty. Although core decompression (CD) and superselective intra-arterial perfusion have been applied clinically, their long-term efficacy as monotherapy remains limited, and the clinical value of combining these approaches has not been fully clarified.

Obesity significantly influences the future of total knee arthroplasty (TKA). However, body mass index (BMI), the prevailing proxy for obesity, has limited predictive value for TKA outcomes, necessitating a more accurate obesity indicator. This study aimed to assess the utility of the fat-to-muscle ratio (FMR) in predicting postoperative outcomes related to obesity in patients undergoing TKA and compared its predictive value with that of BMI.

Patellar malalignment (PM) is common and a deformed valgus knee is an uncommon contributing factor. A deformed valgus knee can magnify the traction forces laterally during knee extension, consequently leading to PM. Treatment of combined disorders without correction of the deformed valgus knee is often less effective. The objective of this study was to assess the possibility of using the retrograde intramedullary nailing technique with some modifications for the treatment of both disorders.

Osteoarthritis (OA) is a progressive joint disease characterized by cartilage degradation driven by matrix-degrading enzymes. Reproducible ex vivo models are essential for studying early degenerative processes and evaluating potential therapeutics. However, there remains a lack of accessible, cost-effective models that accurately replicate the biochemical environment and early-stage damage of OA. This study aimed to develop and validate a bovine cartilage explant model that replicates key features of early OA through enzymatic induction of tissue damage.

Over the past three decades, orthopedic surgical robots have experienced rapid advancements. This study, a case series, aimed to investigate the effectiveness, limitations, and technical improvements associated with the application of robots in the surgical treatment of bone tumors.

Surgical management of cervical spinal fractures accompanying ankylosing spondylitis (ASCSF) is intractable in clinical practice. There is still debate about whether surgery by a single-anterior approach is enough for treating ASCSF. The purpose of this study is to summarize and share relevant experience and lessons from both our team and the literature.

In total hip arthroplasty, the femoral component design requires a trade-off between initial stability and stress shielding. We designed the new bionic hip arthroplasty (BHA) prosthesis with compression and tension screws to mimic compression and tension trabeculae for bionic reconstruction. This prosthesis is designed to reduce stress shielding by mimicking physiological load transfer while ensuring sufficient initial stability for successful bone integration. This study aimed to biomechanically evaluate the initial stability and migration pattern of the BHA prosthesis under dynamic and static loading conditions.

Tumor-induced osteomalacia with the culprit tumor located in the knee joint is rare in clinical practice, and previous literature has only been seen in case reports, which pose great challenges to the clinical diagnosis and treatment of such patients. The purpose is to elucidate clinical characteristics and orthopedic surgical treatment experience of tumor-induced osteomalacia (TIO) with causative tumor located in the knee joint region.

Femoral component rotation affects knee function and component survival in total knee arthroplasty (TKA). However, the presence of posterior femoral condylar cartilage leads to discrepancies in the femoral posterior condylar axis (PCA) between robotic-assisted TKA and manual TKA. The purpose of this study was to investigate the relationship between the discrepancy in thickness of the medial and lateral posterior femoral condylar cartilage and the discrepancy between robotic-assisted and manual rotation of the femoral component.

Glucocorticoid-induced osteonecrosis of the femoral head (GC-ONFH) represents a devastating complication of steroid therapy, primarily driven by osteoblast apoptosis and impaired osteogenesis. Although selenium (Se) is renowned for its potent bone-protective properties, its therapeutic potential, and specific mechanisms in GC-ONFH remain largely unexplored and thus require further investigation.

Chronic exertional compartment syndrome (CECS) of the forearm is a rare and underdiagnosed condition that mainly affects young athletes. Minimally invasive endoscopic surgical treatment has been shown to reduce complication rates and allow for an expedited return to activity. Evidence on the outcomes of single-portal endoscopic fasciotomy for forearm CECS remains limited. The aim of this study was to describe the results of single-portal endoscopic-assisted fasciotomy in treating forearm CECS.

Multiple imaging criteria are available for assessing fusion following anterior cervical discectomy and fusion (ACDF). In clinical trials, the 3-month postoperative follow-up serves as a critical timepoint for evaluating the efficacy of interventions on accelerating the fusion process. This study aims to determine how applying different fusion criteria influences the conclusions of a comparative analysis.
