Article Synopsis
- The study aimed to compare outcomes between two types of fixation methods for femoral neck fractures in patients 50 years and older: in situ fixation and fixation after closed reduction, using data from five hospitals.
- It included 206 patients aged around 69, finding that fixation failure and reoperation rates were significantly higher in the fixation after closed reduction group (26.7% and 20% respectively) compared to the in situ group (6.8% and 7.5%).
- While osteonecrosis of the femoral head (ONFH) rates were similar in both groups, patients in the in situ fixation group showed better functional scores in Koval's grading at 6 and 12 months compared to the other group
Article Synopsis
- The study focused on translating the International Hip Outcome Tool 12 (iHOT12) into Korean (iHOT12-K) to evaluate its effectiveness for assessing hip arthroscopy outcomes in a Korean population.
- A cohort of 67 patients with femoroacetabular impingement participated in the research, where the iHOT12-K was tested for feasibility, internal consistency, and validity using established questionnaires.
- Results showed that iHOT12-K has excellent internal consistency (Cronbach's alpha of 0.896) and strong convergent validity with other hip-specific questionnaires, confirming its reliability for clinical use in Korea.

August 2024
Article Synopsis
- Treatment strategies for femoroacetabular impingement (FAI) have improved as understanding of its effects on hip health has grown, with early arthroscopic surgery becoming more popular to prevent osteoarthritis progression.
- While arthroscopic surgery is effective and supported by clinical evidence, there's still a risk of complications and the need for reoperations.
- Although adjunctive treatments like biologics and injections may help, their effectiveness in FAI treatment is still debated, emphasizing the need for personalized treatment plans for optimal management.
Background: Mental health disparity is associated with diverse characteristics, such as gender, socioeconomic status, Indigenous identity, immigrant status, race, disability, and sexual orientation. However, intersectional studies on women's mental health have been rare, particularly during the COVID-19 pandemic period.
Methods: Using data from two cycles of the Canadian Community Health Survey (2019 annual data and data from September to December 2020), self-reported mental health outcomes before the COVID-19 pandemic (sample size was 64,880) and during the second wave of the pandemic in the fall of 2020 (sample size of 27,246) were analyzed.
Article Synopsis
- * Most patients (84%) were treated nonoperatively, however, those who underwent surgery (16%) had a higher chance of needing total hip arthroplasty (THA) later on.
- * The findings suggest that the type of initial treatment institution plays a role, with general hospitals showing a higher rate of subsequent THA compared to tertiary hospitals.
Article Synopsis
- Periprosthetic tissue inflammation, often caused by wear debris from polyethylene in joint replacements, poses significant complications in surgeries.
- This study explored the impact of grafting a MEDSAH polymer onto polyethylene surfaces, finding that it reduced pro-inflammatory cytokine expression in mouse osteoblasts but did not affect macrophage inflammation.
- The results indicate that MEDSAH coatings could help reduce inflammation and prevent complications in joint replacements, but further clinical research and biomechanical studies are necessary to confirm their long-term effectiveness.
Article Synopsis
- Hemiarthroplasty is a common treatment for displaced femoral neck fractures in elderly patients, but it carries a risk of dislocation; a new method called the posterior approach with inferior capsulotomy (PAICO) was introduced to improve stability.
- A study compared 25 patients treated with PAICO to a historical control group of 3,477 patients who had a conventional approach and found no dislocations in the PAICO group versus a 1.3% rate in the control group.
- The PAICO technique showed similar operation times and complication rates, and it is recommended for surgeons seeking to minimize dislocation risks in knee surgeries.
The COVID-19 pandemic impacted work and home life exacerbating pre-existing stressors and introducing new ones. These impacts were notably gendered. In this paper, we explore the different work and home life related stressors of professional workers specifically as a result of the COVID-19 pandemic through the gender-based analysis of two pan Canadian surveys: The Canadian Community Health Survey (2019, 2020, 2021) and the Healthy Professional Worker Survey (2021).

Article Synopsis
- The increase in centenarians has led to a rise in hip fractures, which can significantly affect their quality of life and incur high medical costs, yet there is limited research on their outcomes.
- A study observed 68 centenarian hip fracture patients over a period from 2004 to 2019, with 56 patients included for a year-long follow-up, assessing various health metrics and outcomes.
- Results showed a high mortality rate of 39.3% at 1 year post-surgery, with pre-injury mobility being a significant risk factor for mortality, as only 16.1% were able to walk outdoors after surgery.
Article Synopsis
- Osteonecrosis of the humeral head (ONHH) is the second most common type of osteonecrosis, but its epidemiological data is limited compared to osteonecrosis of the femoral head (ONFH).
- A study analyzed data from South Korea's Health Insurance Review and Assessment (HIRA) database from 2008 to 2018 to compare trends in surgical treatment for ONHH and ONFH.
- Findings showed ONHH is less common, occurring mainly in older females, while ONFH predominantly affects middle-aged males; ONHH also has a higher rate of post-traumatic cases and a greater frequency of surgical interventions like arthroplasty.
Article Synopsis
- The meta-analysis evaluates the effectiveness of Floseal, a thrombin-based hemostatic agent, in reducing blood loss and transfusions during total knee arthroplasty (TKA).
- Eight randomized controlled trials (RCTs) with a total of 904 patients were included, finding significant reductions in hemoglobin decline and allogenic transfusion risk but no difference in overall blood loss or drainage volume.
- The study supports the use of Floseal in TKA, recommending further RCTs with extended follow-up to confirm long-term outcomes and safety.
Article Synopsis
- Osteonecrosis of the femoral head (ONFH) involves bone death in the femoral head due to disrupted blood flow, primarily affecting young to middle-aged adults and often leading to hip replacement surgery.
- The condition's incidence is rising, particularly linked to the increased use of glucocorticoids for treating conditions like leukemia, organ transplant, and other diseases.
- The review outlines current knowledge on causes, progression, various stages, and treatment options for ONFH, including ARCO criteria for classifying cases associated with glucocorticoids and alcohol, along with updated staging and classification systems.
Article Synopsis
- * Out of 8,883 matched patients, those on ADT had a higher rate of osteoporotic fractures (3.43%), particularly in the hip, spine, and wrist compared to those not on ADT.
- * Despite the increased fracture risk for ADT patients, there was no significant difference in overall survival between the ADT and non-ADT groups.
Article Synopsis
- In 2018, the Femoral Neck System (FNS) was introduced for fixing femoral neck fractures, but it's not suitable for patients with a proximal femur length (ALPF) shorter than 80 mm, as its shortest bolt is 75 mm long.
- A study measured the ALPF of 261 patients using preoperative CT scans, finding that 8.6% had an ALPF less than 80 mm, which affects their eligibility for FNS surgery.
- The study revealed strong correlations between ALPF and patient height, moderate correlations with weight, bone density, and age, suggesting that measuring ALPF is crucial before surgery to ensure proper treatment options.
Article Synopsis
- The Korean Hip Fracture Registry (KHFR) Study aims to create a nationwide registry to analyze the incidence and risk factors of second osteoporotic fractures in adults with hip fractures, establishing a framework for a Fracture Liaison Service (FLS) model.
- Launched in 2014, the KHFR enrolled over 5,800 participants aged 50 and older, gathering extensive data through annual follow-up surveys to monitor the occurrence of additional fractures.
- The study will focus on identifying modifiable factors related to mortality post-hip surgery and analyze various types of fractures, while also comparing treatment methods and their outcomes over a proposed 10-year period.
Article Synopsis
- This study investigated how total hip arthroplasty (THA) affects knee alignment, specifically looking at the hip-knee-ankle angle (HKA) and factors influencing changes in HKA over time.
- It analyzed data from 266 patients who had THA and measured several parameters in preoperative and postoperative radiographs taken at least five years later, noting significant changes in HKA and the relationship with neck shaft angle (NSA).
- Results indicated that a significant decrease in NSA after THA caused a notable increase in varus alignment of the limb, which could negatively impact the knee's medial compartment due to a narrowing of joint space.
