AI Article Synopsis
- The study explored the effects of tranexamic acid (TXA) on reducing hidden blood loss (HBL) in elderly patients with intertrochanteric fractures.
- Ninety-six patients were divided into two groups: one received a placebo (saline), while the other received TXA before and after surgery.
- Results showed that the TXA group had significantly lower perioperative HBL, decreased blood transfusion rates, and improved blood parameters compared to the control, with no major safety concerns or complications reported.
Article Abstract
Background: This study aimed to determine the efficacy and safety of posttraumatic antifibrinolysis with multidose tranexamic acid (TXA) in reducing perioperative hidden blood loss (HBL) in elderly intertrochanteric fracture patients.
Method: Ninety-six elderly intertrochanteric fracture patients admitted to our department from June 2021 to September 2022 were randomized into two groups. The control group (Group A) received 100 mL of normal saline, while the experimental group (Group B) received 1.5 g of TXA intravenously q12 h from postadmission Day 1 (PAD1) to the day before surgery, and both groups received 1.5 g of TXA q12 h from postoperative Day 1 (POD1) to POD3. Haemoglobin (Hb), haematocrit (Hct), coagulation parameters, fibrinogen degradation product (FDP), and D-dimer (D-D) were recorded from PAD1 to POD3. HBL was calculated using the gross formula and recorded as the primary outcome.
Result: In all-over analyses, the patients in Group B had lower perioperative HBL (on PAD3, POD1, and POD3), preoperative HBL (HBLpre), decline of haemoglobin (ΔHb-on PAD3), allogeneic blood transfusion (ABT) rate, FDP (on PAD3), and D-D (on PAD3) compared with Group A. No significant differences were exhibited in postoperative HBL (HBLpost) between the 2 groups. In subgroup analyses, for patients who received intervention within 24 h, the result is consistent with the whole. For patients who received intervention over 72 h of injury, there were no significant differences in perioperative HBL, ΔHb, ABT rate, FDP, and D-D between the 2 groups. There were no significant differences in APTT, PT, the rate of venous thromboembolism, wound complications, or 90-day mortality between the 2 groups.
Conclusion: For elderly intertrochanteric fracture patients, early posttraumatic antifibrinolysis with multidose TXA is effective in reducing perioperative HBL, which mainly manifests as the reduction of preoperative HBL, especially for patients injured within 24 h. Application of TXA beyond 72 h of injury was ineffective.

Predictors and prognosis of elderly hip fracture patients with perioperative atrial fibrillation: a nested case-control study.
BMC Geriatr

Department of Orthopaedic Surgery, The Third Hospital of Hebei Medical University, No.139, ZiQiang Lu, Shijiazhuang, Hebei, 050051, PR China.
Background: A scarcity of data exists concerning atrial fibrillation (AF) during the perioperative stage of non-cardiothoracic surgery, particularly orthopedic surgery. In addition, given the frequency and significant impact of AF in the perioperative period, therefore our aim was to identify prognosis and predictors of elderly hip fracture patients with perioperative AF.
Methods: An examination of hip fracture patients at the Third Hospital of Hebei Medical University, who had been hospitalized from January 2018 to October 2020 in succession, was conducted retrospectively.

Rett syndrome (RS) is a rare neurodevelopmental disorder primarily caused by mutations in the X-linked methyl-CpG binding protein 2 (MECP2) gene, responsible for encoding MECP2 which plays a pivotal role in regulating gene expression. The neurological and non-neurological manifestations of RS vary widely in severity depending on the specific mutation type. Bone complications, mostly scoliosis but also osteoporosis, hip displacement, and a high rate of fractures, are among the most prevalent non-neurological comorbidities observed in girls with RS.

Patients with radiographic axial spondyloarthritis (r-axSpA) experience a higher prevalence of fragility fractures, though the pathophysiology of osteoporosis associated with this disease remains poorly understood. The objective of this study was to evaluate the histomorphometric data in r-axSpA patients. Male r-axSpA patients up to 55 years old were enrolled in this cross-sectional study.

Objective: By comparing the hip arthroplasty parameters planned with the AIHIP three-dimensional simulation surgery system, this study analyzes the accuracy of the new femoral-side "shoulder-to-shoulder" artificial anatomical marker positioning method in femoral-side prosthesis implantation and the prevention of leg length discrepancy in hip arthroplasty.
Methods: A retrospective collection of 47 patients who underwent initial total hip arthroplasty at our hospital from August 2020 to December 2022 and met the inclusion and exclusion criteria was used as the study subjects. The average age was 67.
Irreducible Intertrochanteric Fractures: Analysis of Various Fracture Patterns and Reduction Techniques.

Background Numerous classifications exist for intertrochanteric (IT) fractures, commonly focused on stability. However, the currently utilized Arbeitsgemeinschaft Osteosynthesefragen and Orthopaedic Trauma Association (AO/OTA) classification has limitations in identifying irreducible fractures. This study aims to answer the following questions: does fracture stability imply irreducibility; which fracture fragments complicate reduction; and which reduction techniques should be employed? Materials and methods Eligibility criteria included fractures in adult long bones without pathological fractures being treated by native conservative means.
