METHODS: Retrospective chart review.
OBJECTIVE: Transforaminal lumbar interbody fusion (TLIF) via open or minimally invasive (MI) techniques is commonly performed. Mobile applications for home-based therapy programs have grown in popularity. The purpose of this study was to (1) compare patient-reported outcome measures (PROMs) between postoperative patients who were the most and least compliant in using the mobile-based rehabilitation programs, (2) compare PROMs between open vs MI-TLIF cohorts, and (3) quantify overall compliance rates of home-based rehabilitation programs.
METHODS: A retrospective chart review was performed. Patients were automatically enrolled in the rehabilitation program. Patient-Reported Outcomes Measurement Information System (PROMIS) and Oswestry Disability Index (ODI) scores were collected. Patients were separated into two study groups. Compliance rate was calculated as the difference between the number of active participants at the preoperative phase and final follow-up.
RESULTS: 220 patients were included. Average follow-up time was 23.2 months. No difference was found in the change in (∆) PROMIS scores (P = 0.261) or ∆ODI scores (P = 0.690) regardless of patient compliance. No difference was found in outcome scores between open vs MI-TLIF techniques stratified by download compliance (downloaded, DL+; did not download, DL-) and phone reminder compliance (set reminder, R+; did not set reminder, R-) postoperatively. Both cohorts demonstrated clinical improvement exceeding minimal clinically important difference at final follow-up. Overall patient compliance was 71% at final postoperative follow up.
CONCLUSIONS: Despite high long-term compliance and rising popularity, mobile applications for home-based postoperative rehabilitation programs have low clinical utility in patients undergoing TLIF.

BACKGROUND: Fractures of the lower trunk are among the most common fractures occurring in the elderly. Super elderly individuals (i.e., those 80 years of age and older) represent a growing segment of the population and are especially prone to these fractures. The contemporary epidemiology of lower trunk fractures in the super elderly population is incompletely described in the literature.
METHODS: This descriptive epidemiology study used the National Electronic Injury Surveillance System (NEISS) to examine the incidence and recent trends of lower trunk fractures (i.e., fractures of the hip, pelvis, and lumbar spine) occurring among super elderly individuals in the United States (US) from 2011 to 2020. Annual, overall, and age-/sex-specific incidence rates (IRs) were analyzed. Average annual percent change (AAPC) estimates were calculated to indicate the magnitude/direction of trends in annual injury rates.
RESULTS: An estimated N=1,226,160 super elderly patients sustained lower trunk fractures over the 10-year study period for an overall IR of 100.2 per 10,000 person-years at-risk (PYR). Hip fractures accounted for the largest percentage of cases (IR=71.7 PYR), followed by lumbar spine fractures (IR=14.7), and pelvic fractures (IR=14.3). The incidence of lower trunk fractures among super elderly females (IR=121.5 PYR) was significantly greater than that of males (IR=65.7 PYR). The incidence of lower trunk fractures among nonagenarians and centenarians was significantly higher than that of octogenarians. Accounting for population growth yielded a significantly increasing annual incidence of lower trunk fractures in super elderly patients over the study period from 86.7 PYR in 2011 to 107.2 PYR in 2020 (AAPC=2.7, p<0.001). The annual incidence of both pelvic (AAPC=5.8) and lumbar spine (AAPC=6.9) fractures increased at a significantly higher rate than that of hip fractures (AAPC=1.4).
CONCLUSIONS: This study suggests that the annual incidence of lower trunk fractures in the oldest cohort of patients in the US (80+ years of age) increased significantly during the recent decade from 2011 to 2020, with pelvic and lumbar fractures in particular becoming increasingly common. Increased incidence rates highlight the need for future research aimed at optimizing outcomes and quality of life in this frail and ever-growing segment of the population.

Sickle cell disease often leads to avascular necrosis (AVN) of the hip joint, resulting in joint pain and restricted range of motion. In cases where traditional treatments like total hip arthroplasty or core decompression may not suffice, the Girdlestone procedure, involving the resection of the femoral head, is considered. This case study centers on a 19-year-old male nursing student with sickle cell disease who underwent a Girdlestone procedure at 16 years of age, seeking relief from hip pain and limited mobility. However, the procedure led to leg length discrepancy and reduced hip function. Subsequent total hip arthroplasty successfully converted the prior procedure into a stable joint, improving the patient\'s range of motion and eliminating pain. The comprehensive surgical approach, including soft tissue releases and postoperative rehabilitation, significantly enhanced the patient\'s quality of life, emphasizing the importance of total hip arthroplasty as a superior intervention post-Girdlestone procedure.

UNASSIGNED: The Malaysian Orthopaedic Journal (MOJ) (ISSN 1985-2533 / 2232-111X) is the official publication of the Malaysian Orthopaedic Association (MOA) and the ASEAN Orthopaedic Association (AOA). In May 2007, MOA published the first standalone issue of MOJ with the aim of disseminating new knowledge and providing updates in orthopaedics, trauma and musculoskeletal research. Since then, MOJ has grown significantly, achieving indexing in numerous databases and attaining a 2nd Quartile (Q2) rank in the Scopus database in 2022. This bibliometric analysis aims to explore the trends and distribution of articles published in MOJ.
UNASSIGNED: Bibliometric data for MOJ was extracted from the SCOPUS database, covering the years from its indexing to 2022. Information such as authors, country, document type, author\'s keywords, citations, and other parameters were extracted using the bibliometrix package in the R Studio software. The data were then presented in tables and illustrative graphs using the same software.
UNASSIGNED: A total of 305 articles were retrieved from the Scopus database during the study period. Two-thirds of the articles were original articles and review articles. The highest number of citations received by an article is 56, and top ten articles in MOJ were authored by researchers from seven different countries, highlighting the journal\'s diversity. Despite receiving submissions from various countries, there is minimal collaboration between authors of different countries. Keywords such as \"covid-19\" and \"pandemic\" dominate the authors\' keyword section due to the once-in-a-life-time COVID-19 which during the study period, resulting in numerous publications related to this issue.
UNASSIGNED: This bibliometric analysis reviews all the articles indexed in the Scopus database and provides insight into the contributors\' information and the trends in orthopaedic research. By identifying the lack of collaboration between countries, it is hoped that this analysis can inspire more orthopaedic surgeons and researchers to collaborate and produce high-quality publications.

BACKGROUND: As the demand for total knee arthroplasty (TKA) escalates, 90-day readmissions have emerged as a pressing clinical and economic concern for the current value-based health care system. Consequently, health care providers have focused on estimating the risk levels of readmitted patients; however, it is unknown if specific factors are associated with different types of complications (ie, medical or orthopaedic-related) that lead to readmissions. Therefore, this study aimed to (1) determine the overall, medical-related, and orthopaedic-related 90-day readmission rate and (2) develop a predictive model for risk factors affecting overall, medical-related, and orthopaedic-related 90-day readmissions following TKA.
METHODS: A prospective cohort of primary unilateral TKAs performed at a large tertiary academic center in the United States from 2016 to 2020 was included (n = 10,521 patients). Unplanned readmissions were reviewed individually to determine their primary cause, either medical or orthopaedic-related. Orthopaedic-related readmissions were specific complications affecting the joint, prosthesis, or surgical wound. Medical readmissions were due to any other cause requiring medical management. Multivariable logistic regression models were used to investigate associations between prespecified risk factors and 90-day readmissions, as well as medical and orthopaedic-related readmissions independently.
RESULTS: Overall, the rate of 90-day readmissions was 6.7% (n = 704). Over 82% of these readmissions were due to medical-related causes (n = 580), with the remaining 18% being orthopaedic-related (n = 124) readmissions. The area under the curve for the 90-day readmission model was 0.68 (95% confidence interval: 0.67 to 0.70). Sex, smoking, length of stay, and discharge disposition were associated with orthopaedic readmission, while age, sex, race, the Charlson Comorbidity Index, insurance, surgery day, opioid overdose risk score, length of stay, and discharge disposition were associated with medical-related 90-day readmissions.
CONCLUSIONS: Medical-related readmissions after TKA are more prevalent than orthopaedic-related readmissions. Through successfully constructing and validating multiple 90-day readmission predictive models, we highlight the distinct risk profiles for medical and orthopaedic-related readmissions. This emphasizes the necessity for nuanced, patient-specific risk stratification and preventive measures.

This paper aims to outline current practices and examine promising new advancements in the modern management of haemorrhage in orthopaedic trauma. Many prehospital and perioperative haemorrhage control strategies and techniques have been available to clinicians for multiple decades, yet our understanding and utilisation of these practices continues to be refined and optimised. There is a particular focus in this article on issues related to resuscitation and coagulation in trauma. We examine the complex mechanisms that lead to coagulopathy in trauma patients as well as the transformative effect tranexamic acid has had in limiting blood loss. We also explore some emerging technologies such as endovascular interventions and clot-stabilising dressings and devices that are likely to have a significant impact going forward.

UNASSIGNED: Nigeria has a relatively large scientific community that produces an adequate research output among African countries. Not many studies have analysed the research output in orthopaedics and sports medicine from Nigeria and Africa. Hence, we aimed to analyze the research output in orthopaedics and sports medicine from Nigeria and Africa.
UNASSIGNED: We used the SCOPUS data from the Scimago Journal & Country Rank website. It allows us to draw various journal metrics for research.
UNASSIGNED: Between 1996 and 2022, Nigerian research publications in orthopaedics and sports medicine had grown from 4 in 1996 to 39 in 2022 (a 10-fold growth) but overall is 62nd in the world representing 0.07% of publications in the period. In the same period, Africa published 8297 papers in orthopaedics and sports medicine representing only 1.24% of the global publications in this field.
UNASSIGNED: There is low research output in Orthopaedics and Sports Medicine from Nigeria and, the whole African continent. However, there has been a growth in the publications from Africa.

BACKGROUND: Silica-sprayed tubes (SSTs) are often used to transport synovial fluid samples in equine practice. They promote the coagulation of the sample. The objective of the study is to evaluate the effect of SST on bacterial culture.
METHODS: The study was divided into two parts: sterile saline (Part A) and synovial fluid (Part B). Four common bacteria associated with equine synovial sepsis were used: Streptococcus pyogenes, Escherichia coli, Staphylococcus aureus and methicillin-resistant S. aureus (MRSA). Three collection tubes were used: STT, plain (no-additives) and brain and heart infusion (BHI) broth. Bacteria were cultured in horse blood agar plates for 48 h. Outcome variables were negative culture, positive culture and total number of colony-forming units (CFUs). Statistical analysis was performed using Mann-Whitney U test, and significance was set at p < 0.05.
RESULTS: The total number of agar plates read was 1557 (779 saline; 778 synovial fluid). Total negative cultures were 25/779 on saline and 3/778 on synovial fluid. In broth, maximum growth CFU was achieved after 8 h for both saline and synovial fluid for all bacteria. S. pyogenesand E. coli produced a significantly lower number of CFU when in SST compared to plain or broth after 4 h, whereas S. aureus (American Type Culture Collection [ATCC] and MRSA) only after 24 h.
CONCLUSIONS: Silica-containing tubes reduced bacterial proliferation, whereas the use of a BHI broth provided the highest bacterial load in the sample. The use of SST may have a negative effect on bacterial proliferation in samples obtained from clinical cases.

Many people with pain from osteoarthritis (OA) of the knee are either not ready for surgery or may never be surgical candidates. Genicular artery embolization (GAE) is a new proposed management for those with pain despite maximum medical management. It has historically been used to manage recurrent spontaneous haemarthrosis following total knee replacement, but newer studies are showing a positive effect in managing pre-arthroplasty knee OA. The goal of this review is to summarise current and relevant literature from searches of computerised databases and relevant journals, and analyse their results. Studies included show that GAE has promising outcomes in managing mild to moderate OA knee pain in those who have exhausted at least 3 months of conservative therapy. Most studies show improvements in VAS pain and PROM scores (including KOOS, and/or WOMAC). Minimal adverse effects have been associated in up to two years of follow up, the majority of which are self-resolving. The article précises a concise general procedural technique for performing GAE, as well as comparing and contrasting different embolic agents that may be utilised. GAE shows promising outcomes in management of mild to moderate OA knee pain. In the future, there will need to be higher volume studies to determine effectiveness, suitable candidates, and other potential adverse effects.
