Introduction

Hip fractures represent a significant healthcare burden, particularly among the elderly population, with substantial associated morbidity, mortality and healthcare costs. One of the most distressing aspects of hip fractures is the acute pain experienced by patients, which not only diminishes their quality of life but also poses challenges in postoperative recovery and rehabilitation. In recent years, there has been growing interest in the role of regional anesthesia techniques, such as Pericapsular Nerve Blocks (PNBs), in managing hip fracture pain. This multicenter study aims to investigate the impact of PNBs on pain management, functional outcomes and healthcare resource utilization in patients with hip fractures. Hip fractures, often resulting from falls or trauma, are associated with significant pain, functional impairment and healthcare resource utilization. Traditional analgesic approaches, such as systemic opioids, may be inadequate or associated with adverse effects, highlighting the need for alternative pain management strategies. Pericapsular Nerve Blocks (PNBs) have emerged as a promising technique for providing targeted pain relief while minimizing systemic opioid requirements and preserving lower limb function. Despite growing interest in PNBs, there remains a need for robust evidence regarding their efficacy, safety and impact on patient outcomes in the context of hip fractures. This multicenter study endeavors to address this gap by rigorously evaluating the role of PNBs in optimizing pain management and functional recovery in hip fracture patients across diverse clinical settings [1,2].

Description

Pericapsular nerve blocks involve the injection of local anesthetic agents around the hip joint capsule, targeting the articular branches of the femoral, obturator and accessory obturator nerves. By selectively blocking sensory innervation to the hip joint, PNBs offer effective pain relief while minimizing motor blockade, thereby preserving lower limb function and facilitating early mobilization. This study will evaluate the efficacy and safety of PNBs in a multicenter cohort of hip fracture patients, assessing both short-term outcomes, such as pain scores and opioid consumption, as well as longer-term endpoints, including functional recovery, length of hospital stay and incidence of postoperative complications. The study will employ a prospective, observational design, enrolling patients presenting with hip fractures across multiple participating centers. Baseline demographic and clinical characteristics will be recorded, including age, sex, comorbidities, fracture type and preexisting pain scores. Patients will undergo standardized preoperative assessment, including neurovascular examination and baseline pain assessment using validated pain scales. Those eligible for inclusion will undergo standardized PNB procedures by trained anesthesia providers, utilizing ultrasound guidance to ensure accurate needle placement and optimal block efficacy [3].

Postoperatively, pain scores will be assessed at regular intervals using standardized pain scales, with opioid consumption recorded as a surrogate measure of analgesic efficacy. Functional outcomes, such as ambulation status, mobility and activities of daily living, will be evaluated at predefined time points throughout the hospital stay and during follow-up visits. Healthcare resource utilization parameters, including length of hospital stay, incidence of postoperative complications and healthcare costs, will also be analyzed to assess the economic impact of PNBs in the management of hip fractures. Statistical analyses will be performed to compare outcomes between patients receiving PNBs and those managed with conventional analgesic regimens. Subgroup analyses will be conducted to explore the influence of patient demographics, fracture characteristics and perioperative variables on treatment outcomes. Additionally, sensitivity analyses will be performed to assess the robustness of the findings and identify potential confounding factors. Furthermore, subgroup analyses will be conducted to examine the differential effects of PNBs based on factors such as fracture type, surgical approach and presence of comorbidities. This nuanced approach will help tailor pain management strategies to individual patient profiles, optimizing treatment outcomes and enhancing patient-centered care. Beyond its clinical implications, this study holds potential significance for healthcare policy and resource allocation. By demonstrating the efficacy and cost-effectiveness of PNBs in the management of hip fractures, the findings may inform decision-making at institutional and governmental levels, guiding the implementation of evidence-based practices and allocation of healthcare resources to maximize patient benefit [4,5].

Conclusion

In conclusion, this multicenter study aims to provide valuable insights into the role of pericapsular nerve blocks in the management of hip fracture pain. By comprehensively evaluating the impact of PNBs on pain relief, functional recovery and healthcare resource utilization, this study seeks to inform clinical practice and enhance patient care in this vulnerable population. Through collaborative efforts across multiple centers, we can elucidate the potential benefits of PNBs in optimizing outcomes for patients with hip fractures, ultimately improving their quality of life and reducing the burden on healthcare systems. By leveraging the collective expertise and resources of multiple participating centers, this study endeavors to overcome limitations associated with single-center studies, including sample size constraints, selection bias and generalizability issues. Through collaboration and knowledge sharing, we can harness the collective wisdom of the medical community to address pressing clinical challenges and enhance patient care. Ultimately, the findings of this multicenter study have the potential to transform the landscape of hip fracture management, paving the way for personalized, evidence-based approaches that prioritize patient comfort, functional recovery and overall well-being. By embracing innovation and evidence-based practice, we can strive towards better outcomes and improved quality of life for individuals affected by hip fractures, thereby fulfilling the fundamental mission of healthcare to alleviate suffering and promote healing.
