Hip – pubmed Results

CONCLUSIONS: Despite a small statistical difference in the absolute anteversion error, the pinless AR-based navigation system demonstrated acceptable measurement accuracy and comparable target achievement rates relative to the conventional system requiring pin insertion in this retrospective cohort. While the new pinless AR-based navigation system eliminates the risk of pin-site complications and intraoperative navigation abandonment, and offers instantaneous registration, further prospective...

CONCLUSIONS: Eliminating routine gabapentinoids from a total joint arthroplasty ERAS pathway was associated with lower observed rates of postoperative hypotension and substantially lower gabapentinoid exposure. This quality improvement initiative demonstrates how multidisciplinary review, electronic order set evaluation, and structured monitoring can support safer medication use and improve the reliability of perioperative care pathways.

To quantify the three-dimensional shift of the femoral head after periacetabular osteotomy and to identify the relevant morphological factors. This retrospective study included 26 patients (30 hips) who underwent periacetabular osteotomy at a single institution. Pre- and postoperative supine and standing anteroposterior two-dimensional images and pelvic computed tomography scans were obtained. Using three-dimensional-to-two-dimensional model-image registration techniques, we quantified...

CONCLUSIONS: The FNS provides rotational stability for Pauwels type III fractures comparable with multiple screw fixation and reduces stress at the fracture site. The DHS with an antirotation screw was less stable during hip rotation. Given its greater compressive strength than multiple screw fixation, the FNS is the preferred fixation option.

Osteoarthritis is a leading cause of lower-limb arthroplasty, and although total hip arthroplasty (THA) and total knee arthroplasty (TKA) reduce pain and improve quality of life, gait impairments often persist after surgery. This study aimed to analyze gait patterns in individuals following THA and TKA using the wearable RunScribe™ sensor system and to examine its sensitivity to short-term changes during rehabilitation. Thirty-seven patients (19 THA, 18 TKA) attending a two-week inpatient...

CONCLUSION: Following the introduction of working hour limitations, supervised teaching increased substantially. Although complication and mortality rates rose-likely reflecting an older and more complex patient population-hospital stays shortened. The proposed 42 + 4-hour model will require targeted compensatory measures to maintain surgical training quality and patient safety.

INTRODUCTION: Despite limited evidence of efficacy, opioid analgesics are frequently used by patients for chronic pain while awaiting total hip or knee arthroplasty (THA or TKA). Preoperative use of opioids is problematic as it increases the likelihood of postoperative opioid-related adverse drug events and postoperative complications and is the strongest predictor of persistent opioid use post surgery. Opioid tapering prior to elective surgery has been proposed as a strategy for mitigating...

CONCLUSION: PENG+LFCN may be a more favorable regional analgesic strategy than FICB for hip surgery within ERAS pathways.

Pauwels type III femoral neck fractures are biomechanically challenging because the steep fracture orientation produces dominant shear forces at the fracture interface. This study evaluated key finite element (FE) modeling parameters for simulating fracture fixation and validated numerical predictions against cadaveric experiments. Human femora were fractured at 70° and tested under physiological axial loading to measure construct stiffness and interfragmentary motion (IFM). Eight finite element...

CONCLUSIONS: TRT in THA patients was associated with a reduced rate of surgery-related 90-day ED visits but an increased rate of non-surgery-related 90-day ED visits. Incidence of PJI and overall 90-day ED visits and readmission rates did not significantly differ. Administration form had no significant impact, while higher testosterone levels were linked to fewer 90-day ED visits. Although limited by its retrospective design and patient exclusions, further investigation is warranted to guide...

CONCLUSION: There is no difference in PROMs between public and private hospitals after primary THA, TKA and UKA in the Netherlands. Based on mean travel distance, access to care was not compromised for high-risk patients.

CONCLUSION: COVID-19 vaccination is associated with a reduction in the mortality risk among hip-fracture patients with recent infection. Shorter infection-to-surgery intervals are associated with increased mortality risk, and recent infection is associated with higher VTE risk.

CONCLUSIONS: Long-term trajectories and cumulative exposure of TyGFI were independently associated with hip fracture risk, suggesting that persistent metabolic-frailty imbalance contributes to skeletal fragility. TyGFI may serve as a practical integrative marker for early identification and prevention of high-risk individuals.

CONCLUSIONS: During the study period, the annual referral rate nearly doubled without a corresponding increase in DDH incidence, suggesting that the screening programme has become less efficient over time. This might explain the relatively low incidence of DDH in the North Denmark Region compared with national and international studies.

CONCLUSION: THRs impose a substantial environmental burden, and sustainable solutions should focus on the primary drivers of this impact: disposable utensils, implants and the sterilisation process. In contrast, clinical infrastructure and non-disposable utensils appear to have a relatively minimal environmental impact.

CONCLUSION: Second contralateral hip fractures are underrecognized events that significantly reduce long-term mobility, independence, and survival time post-fracture. Most occur within the first two years after the initial fracture, highlighting a critical window for targeted monitoring, fall prevention, and optimized osteoporosis management. Early identification of high-risk patients, especially those discharged to rehabilitation, is essential to mitigate functional decline and mortality.

CONCLUSIONS: This short, collared, metaphyseal-filling stem demonstrated sustained functional improvements and low implant-related complication rates of the prior six-month follow-up through a minimum of two years. These results support the continued clinical efficacy and stability of the implant in robotic-arm assisted DAA THA.

This study compared the volume of acetabular bone resection between an anatomically designed cementless ceramic-on-ceramic hip resurfacing arthroplasty (H1HR) and metal-on-metal hip resurfacing (Birmingham Hip Resurfacing; BHR). We hypothesized that the anatomical design of the H1 cup would reduce the need for medialization to avoid rim overhang, thereby preserving acetabular bone stock. A retrospective three-dimensional simulation study was performed in 12 hips with osteoarthritis and femoral...

CONCLUSIONS: Reconstructive hip surgery was associated with short-term radiographic improvement and improved caregiver-reported outcomes in this cohort of non-ambulatory children with spastic cerebral palsy. Although 12-month redislocation was lower after VDRO + Dega, the non-randomized design, baseline imbalance, and short follow-up limit comparative inference.

Aseptic osteolysis induced by ultra-high-molecular-weight polyethylene (UHMWPE) wear debris has historically been a major cause of late failure in total hip arthroplasty, highlighting the need for more robust methods to isolate and identify wear particles in complex biological matrices. To validate an optimized protocol for the isolation and identification of UHMWPE wear debris from hip simulator lubricant serum by combining lyophilization, alkaline digestion, and chemometric analysis based on...

CONCLUSION: Conversion THA demonstrates acceptable outcomes, with documented overall improvements in postoperative function. The anterior approach and robotic assistance were associated with significantly shorter surgical times, and less risk of transfusion, potentially demonstrating some advantage in this conversion scenario, although patient selection may have also influenced outcomes.

CONCLUSION: Compared with traction-table positioning, lateral decubitus cephalomedullary nailing was associated with better functional outcome, shorter operative and fluoroscopy times, and lower estimated blood loss, while union and complication rates were similar between groups. These findings suggest that lateral decubitus positioning is a viable alternative for subtrochanteric fracture fixation, particularly when traction-table setup may compromise operating-room efficiency. Given the...

Background and Objectives: Hip fracture surgery is considered a major operation due to the risk of complications and increased mortality. COVID-19 is a newly recognized risk factor for increased mortality in regard to various diseases. Materials and Methods: The aim of this retrospective observational study, conducted from January 2018 to April 2022, was to analyze mortality among rehabilitation ward patients after surgical treatment of acetabular or femoral fractures in both the COVID-19 and...

Leg length discrepancy is a common and clinically important complication following total hip arthroplasty. It may lead to patient dissatisfaction, altered gait, and functional impairment. Although radiographic assessment is widely used, existing measurement methods can be affected by pelvic rotation and anatomical variations. This study aimed to evaluate the reliability and validity of a novel radiographic method based on the distance between the greater trochanter and the ischial tuberosity for...

CONCLUSION: We developed and validated a practical nomogram that effectively predicts the risk of postoperative shock in elderly hip fracture patients using four preoperative parameters. This model may assist clinicians in early risk stratification and perioperative monitoring of elderly hip fracture patients.

CONCLUSIONS: Both Type A and Type B modular tapered fluted stems demonstrated durable fixation, minimal subsidence, low complication rates, and excellent mid-term functional recovery. Radiographic stem subsidence did not differ between groups, indicating that design variations do not significantly affect clinical outcomes. These findings support the use of modular tapered fluted stems as reliable solutions in complex femoral rTHA.

CONCLUSION: After THA/TKA, patient satisfaction is associated with pain during basic daily tasks-especially walking and stair climbing. Key functional drivers differ by joint: socks and stairs matter for THA, rising from sitting and getting in/out of a car matter for TKA.

CONCLUSION: LUS and DM effectively predicted PPCs in geriatric patients with hip fractures. The integration of LUS and DM with ARISCAT markedly enhances predictive accuracy, suggesting that lung and diaphragmatic ultrasound may serve as useful bedside tools for perioperative respiratory risk assessment.

CONCLUSIONS: Cemented THA was associated with reduced rates of periprosthetic fracture, transfusion, and deep vein thrombosis without increasing other perioperative or medical complications. These findings suggest that cemented fixation may be associated with favorable short-term outcomes in selected patients.

CONCLUSION: Among surgically treated hip fracture patients, SV was associated with higher odds of long LOS and discharge to home but no meaningful difference in readmissions. The small number of patients with clinically documented SV highlights the limited reporting by healthcare workers. This analysis of a nationwide all-payer database highlights the need to identify these higher risk patients and implement appropriate care pathways to reduce healthcare utilization.

CONCLUSIONS: The adult PHILOS plate with 3.5-mm locking screws demonstrated inferior biomechanical stability compared with three 6.5-mm cannulated screws in this synthetic composite femur model.

SYNOPSIS: Access to timely care for hip and knee osteoarthritis (OA) is a growing issue. In Canada and Australia, wait times for total hip and knee joint replacements have risen steadily over the past decade, leaving many patients experiencing increased frailty, and reduced function and quality of life while waiting for surgery. These issues are often framed as problems of surgical capacity. We argue they are warning signs of health care systems failing to deliver effective nonsurgical care...

CONCLUSION: This case highlights the importance of early fixation in preserving femoral head viability in combined acetabular and femoral neck injuries.

CONCLUSIONS: For young athletes with hip labrum tears, it is more difficult to schedule appointments with Medicaid insurance compared with BCBS insurance. The main barrier to care with Medicaid for young athletes is requiring a primary care physician referral.

CONCLUSIONS: Integration of preoperative metabolomics and machine learning enabled accurate prediction of POD in older adult patients with hip fracture, facilitating personalized risk stratification and tailored clinical management.

CONCLUSION: In patients with moderate-to-severe hip OA, THA combined with postoperative rehabilitation provides clinically meaningful improvements in pain, function, and HRQoL compared with a self-directed exercise programme alone. These findings reinforce THA as the preferred option for eligible patients.

CONCLUSION: This is the largest survey of UK consultant hip surgeons providing an understanding of the determinants of choices of the type of THA when undertaking primary THA in patients with hip osteoarthritis. These findings will inform the implementation of the findings of studies involving THA in relation to the practices of surgeons in the 'real world'.

CONCLUSION: Cemented femoral fixation THA is the most preferred strategy (highest expected NMB at λ) for NDFNFs in 65-year-old patients. When evaluated against a λ of $4,166.67 per QALM, cemented THA outperforms cementless THA, HHA, IF, and conservative treatment.

Advances in 3D printing, known as additive manufacturing (AM), have allowed for the production of highly porous trabecular metals (TMs) that aim to 'mimic' human bone and facilitate bony ingrowth. AM is increasingly being used to produce acetabular implants which incorporate TMs to varying degrees, to try and create a well-fixed acetabular component and, as a result, reduce the rate of aseptic loosening. This review details the history of uncemented acetabular implants and the developmental...

CONCLUSION: PFFs are associated with an increased mortality risk, and result in functional decline. Coding limitations mean most PFFs are likely missed in arthroplasty registries, underestimating the true incidence. National registry integration and tailored multidisciplinary pathways, similar to those for NHF, are essential for improving outcomes and healthcare planning.

CONCLUSION: The JS-BACH classification system showed the best prognostic performance, correlating with all the outcomes which were evaluated and offering a balanced combination of simplicity, clinical use, and predictive value. The host status remained a critical predictor regardless of which classification system was used.

CONCLUSION: Most patients achieve clinically meaningful improvement within the first postoperative year, with further recovery into the second. Elevated BMI, older age, and residual undercorrection reduce the likelihood of reaching thresholds, while concomitant labral repair may temporarily delay early symptom acceptability.

Quantitative electroencephalography (qEEG) has not yet been systematically applied to characterize cortical bioelectrical activity in patients undergoing total hip or knee arthroplasty. The aim of this study was to evaluate pre‑ to post‑operative changes in cortical activity and their relationship with functional outcomes after arthroplasty. Neuroplastic changes were examined in 81 patients with end‑stage osteoarthritis (33 hip, 48 knee) scheduled for primary total joint arthroplasty. All...

CONCLUSION: Reoperation after surgery for a fracture of the hip is common. These novel data can enable informed shared decision-making for this high-risk group of patients.

The aim of this study is to evaluate the effect of post-discharge education provided via tele-nursing on the quality of life and functional independence levels of elderly patients who have undergone surgery due to a hip fracture. This randomized controlled, pre-test/post-test, single-center experimental study included 30 patients in the intervention group and 30 in the control group, conducted between August and April 2023. The intervention consisted of three online video consultations, three...

CONCLUSION: Undergoing combined fascia iliaca plus femoral nerve block was associated with lower pain scores after 30 minutes compared to isolated fascia iliaca block in patients with proximal hip fractures. These patients may benefit from using this single-injection procedure for improved pain control.

CONCLUSIONS: Medicolegal risk after hip fracture care clusters around process-driven failure points, particularly diagnostic delay and ward-based care breakdowns, rather than isolated technical errors. Missed diagnosis was the only independent predictor of plaintiff success in the U.S.

CONCLUSION: Patients who underwent total hip replacement in their place of birth and residence demonstrated better postoperative outcomes compared to those who had relocated.

CONCLUSION: Our computer-assisted measurement technique demonstrates excellent concordance with standard methodologies while offering workflow advantages. These results provide a foundation for implementation within computer vision models for automated spatial positioning recognition. Future development will focus on enhancing automation, validating across diverse populations and implant designs, and comparing with 3D computed tomography (CT) measurements.

CONCLUSION: This study highlights SES-based disparities in hip fracture patients perioperatively, though both groups converge to comparable outcomes by 1 year. Health policies should consider MH support during recovery for all, regardless of SES.
