Effect of Tranexamic Acid (TXA) on Reduction of Postoperative Blood Transfusion

Tranexamic Acid (TXA) is an antifibrolytic medication used in total hip and knee arthroplasty to reduce the need for intraoperative and postoperative blood transfusions. Limited research is available on its use in hip fracture patients. We hypothesize that the use of TXA preoperatively, perioperatively, and postoperatively will decrease blood loss and need for blood transfusion postoperatively.

PENG Block + LIA For Endoprosthesis Surgery

The goal of this clinical trial is to learn if a new local anesthesia technique can control pain as well as the standard spinal anesthesia for adults having hip endoprosthesis surgery. The main questions it aims to answer are: * Is the new local anesthesia technique as effective as standard spinal anesthesia in managing pain during the first two days after surgery? * Does the new technique allow participants to move their leg sooner after the operation? Researchers will compare the new local anesthesia technique (numbing medicine injected directly around the hip joint) to standard spinal anesthesia (a numbing injection in the back) to see if the new technique works just as well for pain control while possibly causing fewer side effects like nausea. Participants who join this study will be randomly placed into one of two groups. One group will receive the standard spinal anesthesia before their surgery. The other group will receive the new local anesthesia technique before their surgery. After the operation, researchers will track the amount of extra pain medicine each participant uses and will check their ability to move their hip, knee, and foot.

Cervical Myelopathy in Hip Fracture Patients

Recent evidence has demonstrated a high rate of undiagnosed cervical myelopathy in patients presenting with hip fractures from a ground level fall. Identification and treatment of cervical myelopathy can help prevent falls and future fragility fractures. The purpose of this study is to screen ground level fall hip fracture patients for cervical myelopathy using a history, physical exam, and then offer an MRI if indicated.

Caregivers' eCourse for Recovery After Hip Fracture

We will also 2. test its feasibility and acceptability with family caregivers.

PENG vs Femoral Block for Hip Fracture Analgesia

This study aims to compare the Pericapsular Nerve Group (PENG) block with femoral block for hip fracture pain. Participants presenting to the hospital with a diagnosis of hip fracture and consenting to analgesic block will receive either a PENG or femoral block. The choice of block will be dictated by a randomized monthly schedule, and all participants presenting during each four-week period will receive the designated block. A sub-group analysis will be performed to determine any difference in efficacy in participants with intracapsular versus extracapsular fractures.

How TENS Affects Pain, Medication Use, and Muscle Function in Older Adults With Hip Fractures

The goal of this clinical trial is to learn if transcutaneous electrical nerve stimulation (TENS) can reduce perioperative pain in older adults with hip fractures. It will also evaluate its effects on physiological and psychological outcomes. The main questions it aims to answer are: Does adding TENS to usual care during the preoperative phase reduce pain intensity and analgesic consumption? Does TENS affect pressure pain threshold and vital signs (blood pressure, heart rate, and respiratory rate)? Researchers will compare active TENS to sham TENS (no perceptible stimulation) to see if TENS is effective in reducing pain and improving related outcomes. Participants will: * Undergo a standardized baseline assessment, including evaluation of pain, vital signs, anxiety, discomfort, and pressure pain threshold * Complete questionnaires assessing quality of life, physical activity, depressive symptoms, anxiety, fear of falling, and pain catastrophizing * Be randomly assigned to receive either active TENS or sham TENS * Receive a single 45-minute TENS session * Have their analgesic use recorded for the 24 hours before and after the intervention.

SiFi vs FNB Local Anesthesia for Hip Fracture Surgeries

The goal of this clinical trial is to compare two commonly used local/regional anesthesia techniques in adults patients undergoing hip fracture surgery. The main question\[s\] it aims to answer are: • the impact of both interventions on patient level of pain. • impact on postoperative analgesics administered Participants will be randomly assigned to one of two local/regional anesthesia techniques, either femoral nerve block (FNB) or suprainguinal fascia iliaca block (SiFi). Both techniques are the usual practice at the hospital, and we are NOT aiming to experiment on new anesthesia technique in this study.

Cross-sectoral Rehabilitation of Older High-risk Patients With Hip Fracture

The goal of this observational study is to learn about and monitor the cross-sectoral rehabilitation process in older high-risk patients treated for at fragility fracture of the hip. The main questions aim to answer: * how patients are doing up to one year after hip fracture surgery on different outcomes across the continuum of rehabilitation being offered * what expectations, experiences and satisfaction patients have for the overall rehabilitation process after a hip fracture Participants age 65 and above with home address in Frederiksberg municipality, living in own home, admitted and treated for at hip fracture at Department of Orthopedic Surgery, Bispebjerg Hospital, will be asked for participation.

Posterior Pericapsular Deep Gluteal Block Combined With Pericapsular Nerve Group and Lateral Femoral Cutaneous Nerve Blocks for Hip Surgery Analgesia

This study aims to investigate the efficacy of adding a Posterior Pericapsular Deep gluteal block to two other standard nerve blocks-the Pericapsular Nerve Group block and the Lateral Femoral Cutaneous Nerve block-for patients undergoing orthopedic hip surgery. While standard blocks target the front of the hip, many patients still feel pain in the back (posterior) of the joint. Researchers will compare two groups of patients to see if this triple-block combination provides better pain relief and reduces the need for rescue opioid medications in the 24 hours following surgery.

Endoprosthetic Replacement for Pathological Fractures of the Hip: A 35-year Update

This study will be based on a retrospective review of patients who received endoprosthetic reconstruction for pathologic fracture of the proximal femur. The objectives would be two-fold: (1) to compare rates ofambulation, pain, and survival to the historic cohort and (2) to identify predictors of ambulation in the current population.

Effect of Remimazolam and Propofol on Postoperative Delirium

Remimazolam is an ultra-short acting benzodiazepine agonist which is used widely for general anesthesia and sedation. Remimazolam has several advantages. Remimazolam is rapidly metabolized by tissue esterase that it does not accumulate even after infusion for long periods of time. The presence of reversal agents (flumazenil) is also advantageous. Also, hemodynamic stability compared to propofol gives clinicians preference to use for geriatric anesthesia. However, the study on the effect of remimazolam compared to propofol on postoperative delirium have not been carried out. The purpose of the study is to compare the incidence of postoperative delirium and recovery profile in elderly patients undergoing orthopedic surgery using either remimazolam or propofol.

Metabolic Profiling of Hematopoietic Stem Cells in Clonal Hematopoiesis (CHIP)

Bone marrow samples will be collected from patients undergoing hip arthroplasty surgery. Blood and bone marrow samples will be used for metabolic profiling and analysis of relevant CHIP mutations. Combined single-cell transcriptomics and mutation-specific single-cell genotyping (biotin-PCR using mutation-targeted primers followed by sequencing) will subsequently be performed. The gene expression profile of wildtype and mutant hematopoietic stem cells will be compared, performing both broad gene set enrichment analysis and targeted analysis of metabolic pathways.

Is liposomal bupivacaine plus bupivacaine superior to ropivacaine in terms of analgesic efficacy, duration of pain relief, opioid consumption, and patient satisfaction? 2. What medical problems do participants encounter when using liposomal bupivacaine plus bupivacaine for PENG block in postoperative pain management following hip replacement surgery? Researchers will compare liposomal bupivacaine plus bupivacaine to ropivacaine (a routinely used regional anesthetic in clinical practice) to determine if liposomal bupivacaine plus bupivacaine is more effective for pain management following hip replacement surgery. Participants will: 1. Receive liposomal bupivacaine plus bupivacaine or ropivacaine as a regional anesthetic for PENG block under ultrasound guidance. 2. Undergo hip replacement surgery under spinal anesthesia. 3. Have pain relief, opioid analgesic consumption, and incidence of complications assessed at multiple time points within 72 hours after surgery.

Evaluating a Strategy to Improve Pre-Anesthesia Care Discussions (My Anesthesia Choice-Hip Fracture)

The objective of this study is to assess the implementation process for and the effectiveness of a quality improvement (QI) strategy to increase shared decision-making around anesthesia options for hip fracture surgery at 6 US hospitals.

One Versus Two Doses of Tranexamic Acid in Surgically Treated Extracapsular Hip Fractures

The goal of this clinical trial is to learn whether giving one dose or two doses of tranexamic acid can safely lower blood loss in older adults having surgery for certain hip fractures. The study includes adults aged 65 years or older who need surgery for pertrochanteric or subtrochanteric hip fractures. The main questions the study aims to answer are: * Does giving two doses of tranexamic acid lower the need for blood transfusions compared to one dose? * Does tranexamic acid help keep hemoglobin levels higher after surgery? * Is tranexamic acid safe in this group of participants? Researchers will compare participants who receive one dose of tranexamic acid with those who receive two doses to see which approach works better and is safe. Participants will: * Receive either one dose of tranexamic acid before surgery or two doses, one before and one after surgery * Have standard surgery to fix their hip fracture within 48 hours of hospital admission * Be monitored during their hospital stay for blood loss, transfusions, and medical problems * Be followed for up to 90 days after surgery to check for safety A total of 120 participants will take part in this study, which is being conducted at the University Clinic "St. Naum Ohridski" in Skopje, North Macedonia.

This study aims to understand how multiple treatment variables, including pain, rehabilitation time, cost, and choice of surgical versus non-surgical intervention, impact patients' decision-making processes and ultimate choice of treatment.

Evaluation of Fracture Migration After Internal Fixation of Femoral Neck Fractures in Younger Adults: A Clinical RCT Using RSA

The goal of the clinical trial is to compare different surgical methods for internal fixation of femoral neck fractures in younger adults. The main question it aims to answer is: Is internal fixation with the novel implant consisting of three angle stable screws locked together by a plate equal to internal fixation with cancellous screws or a sliding hip screw in younger adults under 65 years of age in terms of fracture migration? The study will examine how stable the fracture remains during healing. This will be measured by assessing how much the fracture moves after surgery using a highly precise imaging method called radiostereometric analysis (RSA). The study will also record complications and evaluate pain, health related quality of life, and hip function over time. The participants will be treated with either a novel angle stable implant (Dynaloc), cannulated cancellous screws or sliding hip screw and followed up at 6 weeks, 12 weeks, 6 months and 12 months. Recruitment will continue until 75 participants, 25 in each group, have completed the 12-week follow-up for the primary outcome.
