RESUMO
PURPOSE: Rising costs in healthcare for total hip arthroplasty (THA) mean that new solutions must be considered, such as the use of single-use ancillaries (SUA). The goal of this study was to assess the accuracy of 2D templating in primary THA for the use of reduced-size SUA. Our hypothesis was that the accuracy of 2D templating in primary THA would be higher than 95%, give or take two sizes. METHOD: This single-centre prospective study included all primary THAs performed over two years. Templating was carried out using 2D templating on anteroposterior pelvic X-rays. The template sizes were compared to the implant sizes. The primary endpoint was the rate of coincidence between digitally templated estimates and the actual implant sizes. The secondary endpoint was the difference of accuracy based on patient parameters. RESULTS: We analysed 512 cases of THA. Accuracy within two sizes was 96.9% for acetabular implants and 98.5% for femoral implants. Accuracy was below the 95% threshold only in patients under 55 and over 85 years old. A BMI above 30.0 kg/m2 significantly reduced accuracy but did not fall below the 95% threshold. The operated hip, the type of implant, and the operative indication did not significantly influence templating accuracy. CONCLUSION: Using reduced-size SUA with five rasps and five reamers depending on template sizes means that THA can be performed in more than 95% of cases allowing the use of compact single use ancillaries.
RESUMO
BACKGROUND: STRATAFIX, a recently introduced barbed suture device, incorporates self-anchoring, knotless sutures with higher tensile strength and enhanced tissue-holding capacity compared to traditional braided absorbable sutures. This study aimed to compare the efficacy of barbed sutures and interrupted sutures in capsular and fascial closure during total hip arthroplasty. METHODS: We retrospectively reviewed the records of patients who underwent total hip arthroplasty between April 2017 and March 2021. Overall, 547 patients were evaluated, comprising 77 men and 470 women (mean age: 64.5 years). Among them, 330 patients were in the interrupted suture (control) group, while 217 were in the barbed suture (BS) group. Data on surgical time, perioperative hemoglobin, length of hospital stay, complications such as transfusions and delayed wound healing, and dislocation rates were collected during the latest outpatient follow-up and compared between the two groups. RESULTS: No differences were observed in intraoperative blood loss between the groups. However, the BS group exhibited significantly longer operative time, as well as significantly lower postoperative blood loss, total blood loss, and postoperative hemoglobin drop compared to the control group. Dislocation was reported in two cases within the control group, whereas no instances were recorded in the BS group. CONCLUSION: The use of barbed sutures demonstrated effectiveness in reducing perioperative blood loss for capsular and fascial closure during total hip arthroplasty.
RESUMO
OBJECTIVE: This meta-analysis aimed to evaluate whether fascia iliaca compartment block (FIB) could reduce the incidence of postoperative delirium (POD) in elderly patients undergoing hip surgery. METHODS: This meta-analysis was registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42023490399). The PubMed, Embase, Web of Science, and Cochrane Library databases were searched for randomized controlled trials (RCTs) till November 15, 2023. Review Manger 5.4 was used to analyze the data. RESULTS: A total of 10 RCTs with 930 elderly patients were included in this meta-analysis. This meta-analysis indicated that FIB could reduce the incidence of POD in elderly patients undergoing hip surgery without preoperative cognitive impairment (OR:0.46; 95%CI[0.22, 0.96], P = 0.04, I2 = 0%). Subgroup analysis of the incidence of POD showed that elderly patients who received FIB treatment before entering the operating room had a lower risk of developing POD(OR:0.48; 95%CI[0.30, 0.76], P = 0.002, I2 = 0%), and FIB could reduce the occurrence of POD in patients undergoing intravertebral anesthesia instead of general anesthesia (OR:0.37; 95%CI[0.20, 0.66], P﹤0.01, I2 = 0%). Moreover, FIB could reduce the MMSE score on the first day after surgery (SMD:1.07; 95%CI[0.15, 1.99], P = 0.02, I2 = 86%). In addition, FIB could reduce the pain score on the first and third day after surgery (SMD: -0.46; 95%CI[-0.74, -0.18], P = 0.001, I2 = 43%; SMD: -0.62; 95%CI[-0.97, -0.26], P﹤0.001, I2 = 58%), as well as after physical activity(SMD: -1.64; 95%CI[-3.00, -0.28], P = 0.02, I2 = 83%). CONCLUSION: FIB can reduce the incidence of POD in elderly patients undergoing hip surgery without pre-existing cognitive impairment. Additionally, it can lower the delirium scores and pain scores.
RESUMO
Background: Threaded acetabular components (TACs) have been shown to offer greater initial stability compared to press-fit acetabular components (PFACs). Despite these biomechanical advantages, the use of threaded cups remains. This study compares the outcomes of TACs to PFACs in total hip arthroplasty (THA), providing evidence-based data regarding their failure rates and radiological evaluation. Methods: A meticulous research of PubMed and MEDLINE databases, following the PRISMA guidelines, was conducted, to identify all articles regarding the outcome of the use of TCAs compared to PFACs in THA. Subsequently, statistical analysis with metanalysis concerning: 1) the instances of revision due to aseptic loosening and 2) the radiological evaluations of TACs compared to PFACs and sensitivity analysis were performed. Results: This metanalysis encompassed seven studies, enrolling 7878 cases of THA utilizing PFAC, and 6684 cases using TAC. The overall odds ratio (OR) for revision due to aseptic loosening in THA using PFAC compared to TAC was 3.10 (95 % CI 0.37-25.72). Additionally, when assessing radiolucency findings across the same categories, the pooled OR was 0.53 (95 % CI 0.26-1.08). An examination of studies with larger sample sizes revealed no statistically significant variance. After adjusting for age, no substantial difference was detected. However, upon gender adjustment, it was observed that females undergoing THA with PFAC had a 5-fold risk of revision (OR = 5.26, 95 % CI 0.25-111.91, p-value = 0.29) compared to females with TAC, although without reaching statistical significance. Moreover, females exhibited a slightly elevated risk for revision due to aseptic loosening post-PFAC THA compared to males [(OR = 5.26, 95 % CI 0.25-111.91) (OR = 2.51, 95 % CI 0.01-1051.68) respectively], and for radiolucency findings [(OR 0.74, 95 % CI 0.20-1.11) (OR 0.29, 95 % CI 0.03-3.36) respectively]. Conclusions: The PFACs remain the main option for total hip reconstruction, while TACs might be a viable alternative, especially in cases of osteoporosis.
RESUMO
Background: Postoperative pain remains a significant challenge after knee and hip surgeries, two of the most frequently performed procedures, preventing patients from seeking timely surgical help. Gabapentinoids, gabapentin, and pregabalin, have been gaining attention in postoperative pain management. Methods: We conducted a meta-analysis to evaluate the efficacy of gabapentinoids in pain management after knee and hip surgery. PubMed, Scopus, and Cochrane Library were searched for relevant randomized controlled trials (RCTs) published before January 2023. Results: Fifteen articles reporting 1320 patients were analyzed. Cumulative pain intensity at rest and on movement was lower in the experimental group with the mean difference (MD) = -0.30 [-0.55,-0.05], p-value = 0.02, and MD = -0.41 [-0.68,-0.13], p-value = 0.004, respectively. However, the difference was not clinically meaningful and lacked statistical significance at each time period. The gabapentinoid group required less opioid consumption in morphine equivalents (MD = -6.42 [-9.07, -3.78] mg, p-value < 0.001). There was a lower incidence of postoperative nausea in the experimental group with a risk ratio (RR) of 0.69 [0.55, 0.86], p-value < 0.001. A subgroup analysis showed that gabapentinoids reduced pain on movement on postoperative day two after total knee arthroplasty but not hip arthroplasty. There was insufficient data to examine the efficacy of gabapentinoids in the reduction of chronic postoperative pain in knee/hip surgery. Conclusions: Thus, gabapentinoids were associated with a reduction in postoperative pain intensity at rest and on movement, morphine consumption, and the incidence of postoperative nausea in the early postoperative period following knee and hip surgeries. However, pain reduction was not clinically relevant. Sedation has not been evaluated in this work and, if performed, this may have influenced the conclusions. An important limitation of this study is that different gabapentinoids, their administration times and dosages, as well as varying intraoperative management protocols, were pooled together.
RESUMO
Intra-articular injections prior to hip arthroscopy are often used to diagnose and conservatively manage hip pathologies, such as femoroacetabular impingement, labral tears, and chondral lesions. As a diagnostic tool, the relief of hip pain following an intra-articular injection helps pinpoint the primary source of pain and assists surgeons in recommending arthroscopic intervention for underlying intra-articular pathologies. However, when injections are not sufficiently spaced apart in time prior to hip arthroscopy, there is an elevated risk of postoperative infection. This systematic review aims to assess whether preoperative intra-articular injections prior to hip arthroscopy are associated with an increased risk of postoperative infection and to determine the safety timeframe for administering such injections prior to the procedure. A comprehensive search was conducted in the PubMed, Embase, and Cochrane Library databases to identify studies examining the relationship between preoperative intra-articular injections and postoperative infection following hip arthroscopy. A meta-analysis was conducted to compare the risk of infection between patients who received injections prior to hip arthroscopy at varying intervals and those who did not receive any preoperative injections. Five studies were included (four level III and one level IV), which consisted of 58,576 patients (58.4% female). Injections administered anytime prior to hip arthroscopy posed a significantly higher risk of infection compared to no history of prior injections (risk ratio: 1.45, 95% confidence interval: 1.14-1.85, P = 0.003). However, upon subanalysis, the risk of infection was significantly higher among patients who received injections within three months prior to hip arthroscopy compared to those who did not receive injections (risk ratio: 1.55, 95% confidence interval: 1.19-2.01, P = 0.001). Additionally, no significant difference in infection risk was observed when injections were administered more than three months before hip arthroscopy compared to no injections (risk ratio: 1.05, 95% confidence interval: 0.56-1.99, P = 0.87). The findings suggest that patients undergoing hip arthroscopy who have previously received intra-articular injections may face a statistically higher risk of postoperative infection, particularly when the injection is administered within three months prior to hip arthroscopy. Consequently, surgeons should exercise caution and avoid administering intra-articular injections to patients scheduled for hip arthroscopy within the subsequent three months to mitigate the increased risk of infection.
RESUMO
BACKGROUND: Total hip arthroplasty (THA) aims to restore joint function and relieve pain. New technology, such as robot assistance, offers the potential to reduce human error, improve precision, and improve postoperative outcomes. The aim of this study was to compare outcomes between conventional and robot-assisted THA. METHODS: This is a retrospective cohort study utilizing a national database from 2016 to 2019. Patients undergoing THA, conventional or robot-assisted, were identified via the International Classification of Diseases, Tenth Revision code. Multivariate regressions were performed to assess outcomes between groups. Negative binomial regressions were performed to assess discharge disposition, readmission, and reoperation. Gamma regressions with log-link were used to assess total charges and lengths of hospital stays. Patient demographics and comorbidities, measured via the Elixhauser comorbidity index, were controlled for in our analyses. A total of 1,216,395 patients undergoing THA, 18,417 (1.51%) with robotic assistance, were identified. RESULTS: Patients undergoing robot-assisted procedures had increased surgical complications (odds ratio [OR] 1.31 [95% confidence interval [CI] 1.14 to 1.53]; P < .001), including periprosthetic fracture (OR 1.63 [95% CI 1.35 to 1.98]; P < .001). Notably, these patients also had significantly greater total charges (OR 1.20 [95% CI 1.11 to 1.30]; P < .001). CONCLUSIONS: Robotic assistance in THA is associated with an increased risk of surgical complications, including periprosthetic fracture, while incurring greater charges. STUDY DESIGN: Level III; Retrospective Cohort Study.
RESUMO
INTRODUCTION: Quality in health services is increasingly associated with enabling patients to participate in their own health and healthcare by recognising their resources and needs. Despite a growing recognition as to whether such participation is enabled, little is known regarding opportunities for preference-based patient participation in orthopaedic care. AIMS: To investigate preference-based participation for patients in orthopaedic care due to hip surgery. METHODS: Patients across 17 Swedish orthopaedic units who had had hip surgery, due to hip fracture or osteoarthritis, January-April 2021 were invited to complete the validated 4Ps questionnaire. Of 1514 patients, 458 patients returned the questionnaire with reports on their preferences for and experiences of participation. Each of the 4Ps' 12 items were analysed separately using descriptive and comparative statistics. RESULTS: A complete match in preferences for, and experiences of, participation was achieved with variation between items for 41%-50% of the patients; if almost matches were included, this occurred for 57%-77% of the patients. Less participation than preferred was most common in terms of having had reciprocal communication, opportunities for partaking in planning, and in learning how to manage symptoms/issues. Hip fracture surgery was significantly associated with experiencing lower levels of participation than preferred. CONCLUSION: Though standardised care promotes efficient hip surgery care, our study suggests a need for more person-centred opportunities to engage. A discrepancy was noted between patients' resources and preparation for their participation in and beyond the hip surgery process, particularly for self-care activities, calling for better use of nursing resources.

RESUMO
BACKGROUND: Allogeneic Blood transfusion is common in hip surgery but is associated with increased morbidity. Accurate prediction of transfusion risk is necessary for minimizing blood product waste and preoperative decision-making. The study aimed to develop machine learning models for predicting perioperative blood transfusion in hip surgery and identify significant risk factors. METHODS: Data of patients undergoing hip surgery between January 2013 and October 2021 in the Peking Union Medical College Hospital were collected to train and test predictive models. The primary outcome was perioperative red blood cell (RBC) transfusion within 72 h of surgery. Fourteen machine learning algorithms were established to predict blood transfusion risk incorporating patient demographic characteristics, preoperative laboratory tests, and surgical information. Discrimination, calibration, and decision curve analysis were used to evaluate machine learning models. SHapley Additive exPlanations (SHAP) was performed to interpret models. RESULTS: In this study, 2431 hip surgeries were included. The Ridge Classifier performed the best with an AUC = 0.85 (95% CI, 0.81 to 0.88) and a Brier score = 0.21. Patient-related risk factors included lower preoperative hemoglobin, American Society of Anesthesiologists (ASA) Physical Status > 2, anemia, lower preoperative fibrinogen, and lower preoperative albumin. Surgery-related risk factors included longer operation time, total hip arthroplasty, and autotransfusion. CONCLUSIONS: The machine learning model developed in this study achieved high predictive performance using available variables for perioperative blood transfusion in hip surgery. The predictors identified could be helpful for risk stratification, preoperative optimization, and outcomes improvement.

Objectives: Diagnosis and treatment of osteoporosis are instrumental in obtaining good outcomes of hip surgery. Measuring bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) is the gold standard for diagnosing osteoporosis. However, due to limited access to DXA, there is a need for a screening tool to identify patients at a higher risk of osteoporosis. We analyzed the potential utility of the Osteoporosis Self-assessment Tool for Asians (OSTA) as a screening tool for osteoporosis. Methods: A total of 1378 female patients who underwent hip surgery at 8 institutions were analyzed. For each patient, the BMD of the proximal femoral region was measured by DXA (DXA-BMD), and the correlation with OSTA score (as a continuous variable) was assessed. Receiver operating characteristic (ROC) curve analysis was performed to assess the ability of OSTA score to predict osteoporosis. Lastly, the OSTA score was truncated to yield an integer (OSTA index) to clarify the percentage of patients with osteoporosis for each index. Results: DXA-BMD showed a strong correlation with OSTA (r = 0.683; P < 0.001). On ROC curve analysis, the optimal OSTA score cut-off value of -5.4 was associated with 73.8% sensitivity and 80.9% specificity for diagnosis of osteoporosis (area under the curve: 0.842). A decrease in the OSTA index by 1 unit was associated with a 7.3% increase in the probability of osteoporosis. Conclusions: OSTA is a potentially useful tool for screening osteoporosis in patients undergoing hip surgery. Our findings may help identify high-risk patients who require further investigation using DXA.
RESUMO
A 52-year-old woman, with a multifaceted medical background encompassing spinal cord injury, pneumonia, and recurrent hospitalizations, presents with enduring left hip and leg discomfort ultimately diagnosed as avascular necrosis (AVN). She previously underwent intraosseous direct anterior arthroplasty (DAA) of the left hip during the removal of orthopedic artifacts. Despite enduring hypertension, severe trochanter dislocation, and prosthesis fracture, she recovered and required additional surgery to address the dislocation and fracture. This case underscores the challenges in diagnosing and treating AVN, emphasizing the importance of meticulous postoperative care and a multidisciplinary approach. Challenges highlighted by AVN include delayed diagnosis, intricate surgical procedures, and the potential need for further interventions due to hardware complications and infection as seen in this patient.
RESUMO
INTRODUCTION: Postoperative urinary retention (POUR) is a common complication after hip surgery. The enhanced recovery urinary protocol (ERUP) is a tool that employs several perioperative strategies to facilitate optimal conditions for surgery and recovery. The aim of this study was to evaluate the effect of ERUP on POUR in patients undergoing hip surgery. METHODOLOGY: A controlled pre- and post-quasi-experimental study was conducted. Data was collected between May 2018 and January 2019 at the orthopedic department of one of the largest teaching hospitals affiliated with Menoufia University in Egypt. A convenience sample of 100 Egyptian patients (of both genders) undergoing elective hip surgery was equally allocated into two groups. The control group (n = 50) was given traditional routine perioperative nursing care, while the intervention group (n = 50) was subjected to ERUP. Data was collected from socio-demographic, medical, and surgical data sheets, preoperative medication assessment sheets, postoperative data sheets, and fluid balance charts. RESULTS: ERUP application significantly reduced the length of hospital stay and the incidence of POUR in the intervention group. CONCLUSIONS: Implementation of the ERUP is recommended for patients undergoing hip surgery, as it has a significantly positive effect on reducing the incidence of POUR.

Urinary retention is a healthcare complication putting patients at risk of unnecessary suffering and harm. Orthopaedic patients are known to face an increased such risk, calling for evidence-based preoperative assessment and corresponding measures to prevent bladder problems. The aim of this study was to evaluate healthcare professionals' adherence to risk assessment guidelines for urinary retention in hip surgery patients. This was an observational study from January 2021 to April 2021 with a descriptive and comparative design, triangulating three data sources: (I) Medical records for 1382 hip surgery patients across 17 hospitals in Sweden were reviewed for preoperative risk assessments for urinary retention and voiding-related variables at discharge; (II) The patients completed a survey regarding postoperative lower urinary tract symptoms, and; (III) data were extracted from a national quality registry regarding type of surgery, preoperative physical status, and perioperative urinary complications. Group differences were analysed with Chi-square/Fisher's exact test, t-test, Wilcoxon rank-sum test, or Mann-Whitney U-test. Logistic regression was used to analyse variables associated with completed risk assessments for urinary retention. Of all study participants, 23.4% (n = 323) had a preoperative documented risk assessment of urinary retention. Whether a risk assessment was performed was significantly associated with acute surgery [odds ratio (OR) 3.56, 95% confidence interval (CI) 2.48-5.12] and undergoing surgery at an academic hospital (OR 4.59, 95% CI 2.68-7.85). Acute patients were more often affected by urinary retention and had bladder issues and/or an indwelling catheter at discharge. More than every tenth patient (11. 9%, n = 53) completing the survey experienced intensified bladder problems after their hip surgery. The study shows a lack of adherence to risk assessment for urinary retention according to evidence-based guidelines, which negatively affects quality of care and patient safety.

Background and Objectives: The number of hip arthroscopy procedures is on the rise worldwide, and awareness regarding proper management of the hip capsule has increased. No capsulotomy shape is agreed upon as a standard approach, with literature supporting both isolated interportal and T-shaped capsulotomies. The aim of this retrospective cohort study is to report the clinical results of a standardized extended interportal capsulotomy (EIPC) during hip arthroscopy. Materials and Methods: Patients operated on between 2017 and 2020 with a hip arthroscopy were eligible. The inclusion criteria were ages 18-60 years, failed non-operative treatment, and at least a 2-year follow-up. Exclusion criteria were bilateral femoroacetabular impingement syndrome (FAS) cases or labral lesions, ipsilateral knee injury, history of ipsilateral hip surgery, and significant spine lesions. Data regarding demographic characteristics such as age, gender, operation date, BMI, but also Beighton score, presence of postoperative pudendal nerve damage, and revision for any reason were gathered from patients' records. All patients were evaluated preoperatively with a visual analog scale (VAS), the Hip Disability and Osteoarthritis Outcome Score (HOOS), and the modified Harris Hip Score (mHHS). Results: Of the 97 patients operated on with a hip arthroscopy between the defined dates, only 90 patients were included. The mean age was 37.9 ± 9.8, and 58.9% of patients were male. The most frequent surgical indication was an isolated FAS lesion (73.3%), followed by FAS associated with a labral tear (12.2%), an isolated labrum tear (10.0%), synovitis (3.3%), and a loose body (1.1%). The mean follow-up for the study cohort was 39.3 months. The majority of the patients had uneventful surgeries (76.7%), while there were three cases of sciatic nerve neuropraxia and 12 cases of pudendal nerve neuropraxia. Two patients underwent revision surgery during the study period. Comparison between preoperative and postoperative clinical scores showed a significant improvement with a final mHHS mean value of 67.7 ± 18.2, an HOOS value of 74.1 ± 13.2, and a low VAS score of 1.3 ± 1.2. Conclusions: A hip arthroscopy procedure with a standardized and unrepaired, extended interportal capsulotomy is a safe procedure with satisfactory mid-term results and high overall patient satisfaction. At a minimum of 2 years and a mean of 39.2 months, patients showed improved clinical scores and a low revision rate.

Total hip arthroplasty (THA) has improved the life quality of osteoarthritic patients, yet challenges persist. The robotic arm-assisted system, integrated into THA, aims to refine implant positioning, enhance precision, reduce errors, and restore the hip joint's anatomy, including hip center, femoral offset, and limb length. We present the first use of the system for the treatment of a subcapital femoral neck hip fracture. A 62-year-old female suffering a left subcapital hip fracture underwent THA using the robotic arm-assisted system. After acetabular registration, accurate component placement was achieved, and a 9-mm limb length discrepancy was addressed. The patient had an unremarkable recovery with a reported Harris hip score of 96.5 at 18 months postsurgery. Robotic-guided navigation in THA, as showcased in this case, ensures accurate implant positioning by restoring the anatomical features of the hip joint. Its potential extends beyond conventional applications, hinting at future use in trauma, revision, and oncology cases. While promising, future adaptations should consider soft tissue dynamics to ensure joint stability and overall success.
RESUMO
The erector spinae plane (ESP) block, initially designed for thoracic analgesia, has evolved into a versatile regional anesthesia technique with literature support for success in numerous contexts. In this case report, we highlight the successful application of ESP to provide postoperative analgesia for pediatric Dega osteotomy involving both the femoral head and acetabulum, in a patient with numerous neurological comorbidities that would have weighed against some more traditional regional anesthesia techniques. This case further highlights the versatility of ESP, demonstrating its use in blocking lumbar nerve roots in a pediatric patient with complex neurological challenges.
RESUMO
PURPOSE: This study aimed to investigate the distance and correlation between the anatomy of the anterior side of the hip joint and the femoral nerve. METHODS: Using ten fresh-frozen cadavers with twenty hip joints. We dissected and marked the femoral nerve in the inguinal area. Employing the direct anterior approach, we identified and marked study points, including the superior and inferior points of the anterior rim of the acetabulum, » point, half point, and ¾ point along an imagined line connecting the formers, the inferomedial and mid aspect of the femoral neck, and the soft spot. Coronal plane measurements gauged the distance between these points and the femoral nerve. The collected data were analyzed to assess the distance and correlation. RESULTS: In the coronal plane, the median distance between the inferior point of the anterior rim of the acetabulum and the femoral nerve was 0 millimeters (interquartile range [IQR] 0-0). Likewise, the median distance between the mid aspect of the medial side of the femoral neck and the femoral nerve was 0 millimeters (IQR 0-0). Additionally, the mean distance between the soft spot and the femoral nerve was 1.18 cm (SD 0.63). CONCLUSION: Surgeons approaching the hip joint via the direct anterior approach should be cautious at the inferior point of the anterior rim of the acetabulum and the mid aspect of the femoral neck. The soft spot at the anterior rim of the acetabulum remains safe from direct injury when surgeons use the correct technique during anterior retractor insertion.

RESUMO
Objectives Developmental dysplasia of the hip (DDH) encompasses a spectrum of abnormalities in the immature hip. Surgical intervention is indicated if conservative management fails. Despite the increased supply of pediatric orthopedic surgeons (POSs) over the last few decades, there continues to be a maldistribution of surgeons. The purpose of this study is to determine outcomes following surgical management of hip dysplasia by POSs compared to non-pediatric orthopedic surgeons. Methods Pediatric patients who underwent surgical treatment for hip dysplasia from 2012 to 2019 were identified using a large national database. Patient demographics, comorbidities, and postoperative complications were compared by pediatric versus nonpediatric-trained orthopedic surgeons. Bivariate and multivariable regression analyses were performed. Results Of the 10,780 pediatric patients who underwent hip dysplasia surgery, 10,206 patients (94.7%) were operated on by a POS, whereas 574 (5.3%) were operated on by a non-pediatric orthopedic surgeon. POSs were more likely to operate on patients with a higher American Society of Anesthesiologists class (p<0.001) and those with a greater number of medical comorbidities, including cardiac (p=0.001), gastrointestinal (p=0.017), and neurological (p<0.001). Following analysis using multivariable regression models to control for patient baseline characteristics, there were no differences in any postoperative complications between patients treated by pediatric-trained and nonpediatric-trained orthopedic surgeons. Conclusions Compared to non-pediatric orthopedic surgeons, POSs were more likely to operate on younger patients with increased medical comorbidities. However, there were no differences in postoperative complications following surgical management for DDH in patients treated by nonpediatric and pediatric orthopedic surgeons.
RESUMO
INTRODUCTION: We analyzed the effect of dexmedetomidine (DEX) as a local anesthetic adjuvant on postoperative delirium (POD) in elderly patients undergoing elective hip surgery. METHODS: In this study, 120 patients undergoing hip surgery were enrolled and randomly assigned to two groups: fascia iliaca compartment block with DEX + ropivacaine (the Y group, n = 60) and fascia iliaca compartment block with ropivacaine (the R group, n = 60). The primary outcomes: presence of delirium during the postanesthesia care unit (PACU) period and on the first day (D1), the second day (D2), and the third day (D3) after surgery. The secondary outcomes: preoperative and postoperative C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), occurrence of insomnia on the preoperative day, day of operation, D1 and D2; HR values of patients in both groups before iliac fascia block (T1), 30 min after iliac fascia block (T2), at surgical incision (T3), 20 min after incision (T4), when they were transferred out of the operating room (T5) and after leaving the recovery room (T6) at each time point; VAS for T1, PACU, D1, D2; the number of patients requiring remedial analgesics within 24 h after blockade and related complications between the two groups. RESULTS: A total of 97 patients were included in the final analysis, with 11 and 12 patients withdrawing from the R and Y groups, respectively. The overall incidence of POD and its incidence in the PACU and ward were all lesser in the Y group than in the R group (p < 0.05). Additionally, fewer cases required remedial analgesia during the PACU period, and more vasoactive drugs were used for maintaining circulatory system stability in the Y group as compared to the R group (p < 0.05). At the same time, the incidence of intraoperative and postoperative bradycardia in the Y group was higher than that in the R group, accompanied by lower postoperative CRP and ESR (all p < 0.05). CONCLUSION: Ultrasound-guided high fascia iliaca compartment block with a combination of ropivacaine and DEX can reduce the incidence of POD, the use of intraoperative opioids and postoperative remedial analgesics, and postoperative inflammation in elderly patients who have undergone hip surgery, indicating that this method could be beneficial in the prevention and treatment of POD.
