Similar complications and outcomes with simultaneous versus staged bilateral total hip arthroplasty with the direct anterior approach: A comparative study.

INTRODUCTION: Simultaneous bilateral total hip arthroplasty (THA) has demonstrated similar clinical outcomes to staged bilateral THA. However, there is scarce data regarding the early postoperative complications. This study compares simultaneous to staged bilateral THA with the direct anterior approach (DAA) regarding early complications and revision surgeries. METHODS: This retrospective case-control study included all bilateral THAs, performed by DAA between 2013 and 2021 with a minimum follow-up of 6 months. A total of 264 THAs (132 patients) were identified [simultaneous group (1T): 58 patients; staged group (2T): 74] with a mean follow-up of 54 months. Complications and revisions, clinical outcomes, and days off work were assessed at the last follow-up. Moreover, blood loss was evaluated by the modified method of Mercuriali and Inghilleri. RESULTS: Blood loss was higher in the 1T group (1003 mL 1T vs. 740 mL 2T; p < 0.001) but there was no significant difference in transfusion rates (5% 1T vs. 3% 2T; p = 0.4). There were no complications in 1T, while the complication rate was 5.2% (n = 6) in 2T (p = 0.012). There were 5 revisions in the 2T group, including 2 debridements with polyethylene exchange and implant retention for early infections, 2 revisions for aseptic loosening in the same patient, and 1 revision due to fracture. Postoperative pain on D3 was equivalent in both groups (4.2 1T vs. 4.3 2T; p = 0.79). The improvement in function according to the HHS at 2 months was better in the 1T group, but not significant (36.8 1T vs. 32.9 2T; p = 0.05). The total number of days off work was significantly higher in the 2T group (82.6 days vs. 178.8; p = 0.025). DISCUSSION: Simultaneous bilateral THA with the DAA seems to be a safe procedure, with no risk of increased early postoperative complications when compared to the staged procedure with similar functional outcomes and significantly fewer complications and days off work.

PCL injury following high energy trauma: associated injuries and postoperative complications "insights from a national registry study".

PURPOSE: The posterior cruciate ligament (PCL) is a vital knee stabilizer. While PCL injuries are rare, high-energy traumas can lead to total ruptures, with accompanying injuries requiring surgery. This study aims to investigate the demographics, concomitant injuries, and postoperative complications of patients who underwent PCL reconstruction due to high-energy trauma in a large patient sample. METHODS: Patients who underwent PCL reconstruction from 2016 to 2022 were retrospectively evaluated using data from a nationwide personal health recording system. Patient demographics, injury mechanisms, associated fractures, soft tissue injuries, and postoperative complications were collected from patient notes, clinical visits, and surgical notes. Individuals with a PCL injury following high-energy trauma (car accident, falls from height, motorcycle accident) with a minimum follow-up of 1 year were included in the study. RESULTS: The study included 416 patients with a mean age of 32.4 years. Isolated PCL injuries (n = 97, 23.3%) were observed less frequently than multiple-ligament injuries (n = 319, 76.7%). Most cases were treated with single-stage surgery (86.8%), while staged surgeries were performed in a minority of cases (13.2%). There was no relationship between trauma mechanisms and multiple-ligament involvement, accompanying injuries, or postoperative complications. Surgeries following car accidents were more likely to occur as staged surgeries (p = 0.014). Additionally, the complication rates for staged surgeries and younger patients (≤ 18 years) were significantly higher (p = 0.009). CONCLUSION: High-energy trauma-induced PCL injuries are often associated with severe concurrent knee injuries with multiple ligament involvement. PCL reconstructions following car accidents are more likely to be staged. These findings highlight the importance of careful consideration in managing these cases to minimize complications, particularly in younger age groups. LEVEL OF EVIDENCE: Level III.

Surgical Management of Ipsilateral Internal Carotid Artery Stenosis and Unruptured Intracranial Aneurysm: Case Review and Treatment Considerations.

Introduction The coexistence of carotid artery stenosis and a concomitant downstream ipsilateral unruptured intracranial aneurysm requires unique treatment considerations to balance the risk of thromboembolic complications from carotid artery stenosis and the risk of subarachnoid hemorrhage from intracranial aneurysm rupture. These considerations include the selection of optimal treatment modalities, the order and timing of interventions, and potential management of antiplatelet agents with endovascular approaches. We present strategies to optimize treatment in such a case. Case Report We discuss the case of a 69-year-old woman with 90% stenosis of the right internal carotid artery and an ipsilateral, wide-necked, 4.8-mm, irregular-appearing right A1-2 junction aneurysm with an associated daughter sac. Open, endovascular, and mixed treatment strategies were considered. The patient selected and underwent a staged, open treatment approach with a carotid endarterectomy followed by a right craniotomy for microsurgical clipping of the aneurysm 5 days later. Both procedures were performed on daily full-dose aspirin without complications. On follow-up, the right carotid artery was widely patent, the aneurysm was secured, and the patient remained at her neurologic baseline. Discussion The presented strategy for ipsilateral carotid artery stenosis and an unruptured intracranial aneurysm initially optimized cerebral perfusion to mitigate ischemic risks while permitting timely aneurysm intervention without a need for dual antiplatelet therapy or to traverse an earlier procedure site.

[Thinking on the application of reinforcing and reducing techniques of moxibustion in the staged differentiation and treatment of prostate cancer].

The effect of reinforcing and reducing techniques of moxibustion depends on types of moxibustion, operation methods and characteristics of acupoints. According to the ups and downs of pathogenic factors and healthy qi during the occurrence and development of prostate cancer, three stages are divided, namely, the stage of initial accumulation of cancer toxicity, the stage of the deficiency of healthy qi and toxin retention, and the stage of yang deficiency and cold stagnation. In the stage of initial accumulation of cancer toxicity, zangfu function is impaired and the dampness, heat and stasis toxin are accumulated in the body; due to which, the reducing technique of moxibustion should be dominant and the healthy qi be supported in combination. In treatment, the wheat-grain sized cone moxibustion, suppurative moxibustion and garlic-isolated moxibustion are applicable. The reducing purpose of moxibustion is obtained by delivering an appropriate increased number of moxa cones, large dosage and strong stimulation at acupoints. In the stage of the deficiency of healthy qi and toxin retention, qi movement is weakened and cancer toxin consumes yin; the reinforcing healthy qi and removing pathogenic factors should be operated simultaneously. In treatment, mild moxibustion and suppurative moxibustion can be used. The reduced number of moxa cones, moderate dosage of moxibustion and mild stimulation at acupoints should be considered to gently adjust the conditions of deficiency and excess. In the stage of yang deficiency and cold stagnation, spleen and kidney yang is deficient, and the meridians are blocked by cold and damp pathogens. In treatment, the reinforcing technique of moxibustion should be used specially and eliminating pathogenic factors be combined. Monkshood cake-insulated moxibustion, salt-insulated moxibustion and wheat-grain sized cone moxibustion can be adopted. The less number of moxa cones, small dosage and appropriately increased frequency of treatment should be considered to produce the gentle and sustained stimulation at acupoints so as to excite the healthy qi and promote the transformation of qi and blood.

MCID achievement in staged bilateral total knee arthroplasty: Are both joints created equal?

BACKGROUND: A notable portion of unilateral total knee arthroplasty (TKA) patients undergo arthroplasty of the contralateral knee. The aims of this study were to describe the Minimal Clinically Important Difference for Improvement (MCID-I) and Worsening (MCID-W) in staged bilateral TKAs (BTKAs) and identify factors associated with these outcomes. METHODS: Patients with staged BTKA were retrospectively reviewed. Demographics, surgery details, and Patient-Reported Outcome Measurement Information System Physical Function Short Form 10a (PROMIS PF10a) were collected. MCID-I and MCID-W were defined for PROMIS PF10a. Patients were stratified into nine groups based on the MCID achievement of the first and second TKA: (A) MCID-I, MCID- I, (B) MCID-I, Neutral, (C) MCID-I, MCID-W, (D) Neutral, MCID-I, (E) Neutral, Neutral, (F) Neutral, MCID-W, (G) MCID- W, MCID-I, (H) MCID-W, Neutral, (I) MCID-W, MCID-W. Neutral patients did not achieve either MCID-I or MCID-W. RESULTS: The final cohort consisted of 59 staged BTKA patients. In patients who achieved MCID-I in the first TKA, 39.1% achieved MCID-I again in the second TKA (A), 39.1% were neutral (B), and 21.7% achieved MCID-W (C) in the second TKA. However, 77.8% of those who achieved MCID-W in the first joint (n = 9) went on to achieve MCID-I (G) in the second TKA. Those who achieved MCID-I after both TKAs (A) had a longer staged interval than those who achieved first MCID-I, then MCID-W (C) (15 months vs 8 months, P = 0.0113). CONCLUSION: In staged BTKA, MCID achievement of the first TKA may not be associated with the outcome of the second TKA.

The INMSG Survey on the Loss of Signal Management on the First Side During Planned Bilateral Thyroid Surgery.

BACKGROUND: The aim of this study is to describe the management and associated follow-up strategies adopted by thyroid surgeons with different surgical volumes when loss of signal (LOS) occurred on the first side of planned bilateral thyroid surgery, and to further define the consensus on intraoperative neuromonitoring (IONM) applications. METHODS: The International Neural Monitoring Study Group (INMSG) web-based survey was sent to 950 thyroid surgeons worldwide. The survey included information on the participants, IONM team/equipment/procedure, intraoperative/postoperative management of LOS, and management of LOS on the first side of thyroidectomy for benign and malignant disease. RESULTS: Out of 950, 318 (33.5%) respondents completed the survey. Subgroup analyses were performed based on thyroid surgery volume: <50 cases/year (n = 108, 34%); 50 to 100 cases/year (n = 69, 22%); and >100 cases/year (n = 141, 44.3%). High-volume surgeons were significantly (P < .05) more likely to perform the standard procedures (L1-V1-R1-S1-S2-R2-V2-L2), to differentiate true/false LOS, and to verify the LOS lesion/injury type. When LOS occurs, most surgeons arrange otolaryngologists or speech consultation. When first-side LOS occurs, not all respondents decided to perform stage contralateral surgery, especially for malignant patients with severe disease (eg, extrathyroid invasion and poorly differentiated thyroid cancer). CONCLUSIONS: Respondents felt that IONM was optimized when conducted under a collaborative team-based approach, and completed IONM standard procedures and management algorithm for LOS, especially those with high volume. In cases of first-site LOS, surgeons can determine the optimal management of disease-related, patient-related, and surgical factors. Surgeons need additional education on LOS management standards and guidelines to master their decision-making process involving the application of IONM.

An Eye on the First Surgical Side: Appreciating the Potential Impacts of a Second DBS Lead on Ipsilateral Symptoms.

Clinical Vignette: A 63-year-old man with severe essential tremor underwent staged bilateral ventralis intermedius (Vim) deep brain stimulation (DBS). Left Vim DBS resulted in improved right upper extremity tremor control. Months later, the addition of right Vim DBS to the other brain hemisphere was associated with acute worsening of the right upper extremity tremor. Clinical Dilemma: In staged bilateral Vim DBS, second lead implantation may possibly alter ipsilateral tremor control. While ipsilateral improvement is common, rarely, it can disrupt previously achieved benefit. Clinical Solution: DBS programming, including an increase in left Vim DBS amplitude, re-established and enhanced bilateral tremor control. Gap in Knowledge: The mechanisms underlying changes in ipsilateral tremor control following a second lead implantation are unknown. In this case, worsening and subsequent improvement after optimization highlight the potential impact of DBS implantation on the ipsilateral side. Expert Commentary: After staged bilateral Vim DBS, clinicians should keep an eye on the first or original DBS side and carefully monitor for emergent side effects or worsening in tremor. Ipsilateral effects resulting from DBS implantation present a reprogramming opportunity with a potential to further optimize clinical outcomes. Highlights: This case report highlights the potential for ipsilateral tremor worsening following staged bilateral DBS and provides valuable insights into troubleshooting and reprogramming strategies. The report emphasizes the importance of vigilant monitoring and individualized management in optimizing clinical outcomes for patients undergoing staged bilateral DBS for essential tremor.

Age-adjusted Charlson Comorbidity Index as an effective tool for the choice between simultaneous or staged bilateral total knee arthroplasty.

INTRODUCTION: The choice between simultaneous and staged bilateral total knee arthroplasty (BTKA) remains controversial. Age-adjusted Charlson Comorbidity Index(CCI) is a promising tool for risk-stratification. We aimed to compare the outcomes between patients who underwent simultaneous and staged BTKA, stratified by age-adjusted CCI scores. MATERIALS AND METHODS: We conducted this retrospective, single-surgeon case series from 2010 to 2020. This study consisted of 1558 simultaneous BTKA and 786 staged BTKA procedures. The outcome domains included 30-day and 90-day readmission and 1-year reoperation events. We performed multivariate regression analysis to compare the risk of readmission and reoperation following simultaneous and staged BTKA. Other factors included age, sex, body mass index, diabetes mellitus, rheumatoid arthritis, smoking, receiving thromboprophylaxis and blood transfusion. RESULTS: The rates of 30-day, 90-day readmission and 1-year reoperation following simultaneous BTKA was 1.99%, 2.70% and 0.71%, respectively. The rates of 30-day, 90-day readmission and 1-year reoperation following staged BTKA was 0.89%, 1.78% and 0.89%, respectively. For patients with age-adjusted CCI ≥ 4 points, simultaneous BTKA was associated with a higher risk of 30-day (aOR:3.369, 95% CI:0.990-11.466) and 90-day readmission (aOR:2.310, 95% CI:0.942-5.668). In patients with age-adjusted CCI ≤ 3 points, the risk of readmission and reoperation was not different between simultaneous or staged BTKA. CONCLUSION: Simultaneous BTKA was associated with an increased risk of short-term readmissions in patients with age-adjusted CCI ≥ 4 points but not in those with age-adjusted CCI ≤ 3 points. Age-adjusted CCI can be an effective index for the choice between simultaneous and staged BTKA procedures.

Shehata technique versus Fowler-Stephens orchidopexy in intra-abdominal testis: A meta-analysis.

INTRODUCTION: The management of intra-abdominal testis (IAT) represents a significant clinical challenge, necessitating the transposition of the testis from the abdominal cavity to the scrotum. This procedure is rendered complex by the abbreviated length of the testicular vessels. OBJECTIVE: Our purpose in this study was to conduct a systematic review and meta-analysis comparing Shehata technique (ST) versus Fowler Stephens technique (FST) in treating patients with IAT. STUDY DESIGN: We conducted a comprehensive literature search using several databases, including Ovid Medline, Cochrane, PubMed, Google Scholar, Web of Sciences, EMBASE, and SCOPUS until February 2024. This study included research that compared ST and FST for managing intra-abdominal testis. We evaluated the rates of atrophy and retraction, as well as the overall success rates, for both techniques. RESULTS: Six studies were identified as appropriate for meta-analysis, comparing orchidopexy performed using the ST with 169 patients, against the FST involving 162 patients. The comparison showed no statistically significant age difference at the time of surgery between the groups (I2 = 0%) (WMD 0.05, 95% CI - 1.24 to 1.34; p = 0.94). Operative time in first the stage was lower in the FST group than ST group (I2 = 95%) (WMD 10.90, 95% CI 1.94 to 19.87; p = 0.02). Operative time in the second stage was lower in the ST group than FST group (I2 = 83%) (WMD - 6.15, 95% CI - 12.21 to -0.10; p = 0.05). Our analysis showed that ST had a similar atrophy rate (I2 = 0%) (OR: 0.45, 95% CI: 0.20 to 1.01; p = 0.05). No difference was found between techniques in terms of retraction rate (I2 = 0%) (OR: 0.64, 95% CI: 0.17 to 2.47; p = 0.52). The ST demonstrated a notably higher overall success rate compared to FST (I2 = 1%) (RR: 1.14, 95% CI: 1.03 to 1.27; p = 0.009). Overall success rate in ST and FST were 87% and 74%, respectively. Overall atrophy rate in ST and FST were 5% and 12%, respectively. Overall retraction rate in ST and FST were 5% and 10%, respectively. DISCUSSION: The ST, renowned for its pioneering two-stage laparoscopic approach that leverages mechanical traction to lengthen the testicular vessels, is gaining popularity due to its recognized safety and efficacy. Conversely, the Fowler-Stephens technique, a traditional method that relies on collateral blood supply for testicular mobilization, has come under examination for its potential link to an increased risk of testicular atrophy. CONCLUSION: This meta-analysis reveals that the Shehata technique has similar or better outcomes compared to the Fowler-Stephens technique in IAT management. Further prospective multicentric randomized controlled trials are warranted.

Staged versus non-staged elective hybrid iliofemoral revascularization - analysis of ten years of prospective data.

INTRODUCTION: Reports of large series of hybrid iliofemoral revascularization for chronic lower limb ischemia are scarce. The aims of this study were to evaluate outcomes for staged and non-staged procedures, and to evaluate risk factors for outcomes at 90 days. MATERIALS AND METHODS: Patients were consecutively included between 2013 and 2023. Surgical site infection (SSI) was defined by the ASEPSIS criteria and major adverse limb events (MALE) as onset of acute or continuing or worsening chronic limb ischemia or major amputation. Factors associated with outcomes were tested in a multivariable logistic regression analysis and expressed in Odds ratios (OR) with 95% confidence intervals (CI). RESULTS: Patients undergoing non-staged procedures (n=124) had higher TASC (Trans-Atlantic Inter-Society Consensus) class representing anatomical occlusive complexity, more often through-and through femoral guidewire access, more endoprosthesis, more covered stents, longer procedure time with open groin wounds, and less contralateral femoral access, than those undergoing staged procedures (n=31). The median time interval between the staged procedures was one day, and iliac stenting was done first in 77%. The median in-hospital stay was non-significantly longer in staged procedure (8 versus 6 days, p=0.053). The overall SSI and MALE rates were 25.8% and 20.0%, respectively, without differences between groups. Diabetes mellitus (OR 3.7, 95% CI 1.2 - 7.2]) and presence of a foot ulcer (OR 3.7, 95% CI [1.5 - 9.4]) were independently associated with MALE at 90 days. Postoperative hyperglycemia was non-significantly associated with SSI (OR 2.1 [95% CI 1.0 - 4.5], p=0.066) in multivariable analysis. CONCLUSION: The risks of SSI and MALE after elective hybrid iliofemoral revascularization were high. There appears to be no benefit in performing staged as opposed to non-staged procedures. The extent of iliofemoral occlusive disease according to the TASC classification had little influence on outcomes whereas diabetes mellitus and presence of a foot ulcer had greater impact on MALE.

Beyond one step: unveiling optimal approach for bilateral knee arthroplasty - a comprehensive meta-analysis.

BACKGROUND: Total knee arthroplasty (TKA) is an efficient and common procedure used to treat advanced osteoarthritis of the knee. Geriatric patients make up the majority of TKA patients. For the surgical management of bilateral knee arthritis, there is still debate regarding whether to do a simultaneous or staged TKA. We through this study have gathered data and aimed to assess the safety of simultaneous bilateral TKA in patients. MATERIALS AND METHODS: We conducted a study according to the PRISMA guidelines by searching through various databases for the following search terms: total knee arthroplasty (TKA), complications following TKA, bilateral TKA, and bilateral vs. unilateral TKA. The search included case series and clinical trials and excluded review articles, yielding 24 articles from the original search. We extracted data upon the outcomes in patients undergoing simultaneous bilateral TKA. We performed additional bias assessments to validate our search algorithm and results. RESULTS: One hundred and three published articles were identified, and twenty-four that included a total of 2, 18,385 patients were included in the meta-analysis. 93,074 patients underwent simultaneous bilateral TKA and 125,311 patients underwent staged bilateral TKA. Simultaneous bilateral TKA was associated with significantly increased mortality rate (P < 0.00001, Odd's ratio [OR] 1.86, 95% Confidence interval [CI] 1.53-2.26), increased incidence of pulmonary embolism (P < 0.00001, OR 1.58, 95% CI 1.30-1.91), deep venous thrombosis (P < 0.00001, OR 1.31, 95% CI 1.17-1.46), and neurological complications (P < 0.002, OR 1.44, 95% CI 1.14-1.82). There were no significant differences in cardiac complications between both the procedures (P = 0.60, OR 0.93, 95% CI 0.70-1.23). CONCLUSION: Staged bilateral TKA is associated with less complication rates as compared to simultaneous bilateral TKA. Hence, patients should be counselled and selected based on the risks respective to each strategy.

Long-Term Outcome of Time-Staged Gamma Knife Radiosurgery for Large Arteriovenous Malformations.

BACKGROUND: Treatment for large (> 10 mL) arteriovenous malformations (AVMs) remains highly challenging. This study evaluated long-term effect of time-staged gamma knife radiosurgery (GKS) for large AVMs. METHODS: For patients with large AVMs treated by time-staged GKS over 10 years, time-staged GKS was repeated every three years targeting the entire nidus if total obliteration was not achieved. Obliteration rate and post-GKS complications were assessed based on 10 mL volume interval of AVMs. Prognostic factors for these outcomes were evaluated using Cox regression analysis. RESULTS: Ninety-six patients were analyzed. For AVMs in the 10-20 mL subgroup, a dose ≥ 13.5Gy yielded higher obliteration rate in the first GKS. In the 20-30 mL subgroup, a second GKS significantly boosted obliteration. AVMs > 30 mL did not achieve any obliteration with the first GKS. Among 35 (36.4%) cases lost to follow-up, 7 (7.2%) were lost due to GKS complications. Kaplan-Meier analysis showed that each subgroup needed different time for achieving 50% favorable obliteration outcome rate: 3.5, 6.5, and 8.2 years for 10-20 mL, 20-30 mL, and > 30 mL subgroup, respectively. Total obliteration rate calculated by intention-to-treat method: 73%, 51.7%, 35.7%, respectively, 61.5% overall. Post-GKS hemorrhage and chronic encapsulated expanding hematoma (CEEH) occurred in 13.5% and 8.3% of cases, respectively. Two patients died. Dose and volume were significant prognostic factors for obliteration. Initial AVM volume was a significant prognostic factor of post-GKS hemorrhage and CEEH. CONCLUSION: Time-staged GKS for large AVMs less than 30 mL has highly favorable long-term outcome and a tolerable complication rate.

Role of liver augmentation prior to hepatic resection - a survey on standards, procedures, and indications in Germany, Switzerland, and Austria.

PURPOSE: For primary and secondary liver tumors oncological resection remains a chance of cure. Augmentation of functional liver tissue may be necessary to preserve sufficient future liver remnant (FLR). Clinical decision-making on liver augmentation techniques and indications may differ internationally. Thus, this study aims to identify standards of liver augmentation in hepato-pancreatico-biliary (HPB) centers in Germany, Switzerland, and Austria. METHODS: Using a web-based survey, 48 hospitals in Germany, Switzerland, and Austria were invited to report their surgical indication, standard procedures, and results of liver augmentation. RESULTS: Forty (83.3%) of the hospitals invited participated. Most of the hospitals were certified liver centers (55%), performing complex surgeries such as liver transplantation (57.5%) and ALPPS (80%). The standard liver augmentation technique in all countries was portal vein embolization (PVE; 56%), followed by ALPPS (32.1%) in Germany or PVE with hepatic vein embolization (33.3%) in Switzerland and Austria. Standard procedure for liver augmentation did not correlate with certification as liver center, performance of liver transplantation or ALPPS. Surgical indication for PVE varied depending on tumor entity. Most hospitals rated the importance of PVE before resection of cholangiocarcinoma or colorectal metastases as high, while PVE for hepatocellular carcinoma was rated as low. CONCLUSION: The survey gives an overview of the clinical routine in HPB centers in Germany, Austria, and Switzerland. PVE seems to dominate as standard technique to increase the FLR. However, there is a variety in the main indication for liver augmentation. Further studies are necessary evaluating the differing PVE techniques for liver augmentation.

Functional assessment and influencing factors after staged functional training in patients with ankle fractures.

BACKGROUND: The recovery of limb function after ankle fracture surgery is a gradual process. The main purpose of implementing early functional exercise, joint mobility, muscle contraction function, passive ankle flexion and extension exercises, or physical factor therapy techniques is to achieve the rapid recovery of normal physiological limb function. However, currently the most effective rehabilitation training method is staged limb functional exercise, which promotes rapid recovery of limb function while preventing adverse consequences caused by overwork or insufficient training. Staged limb functional exercise divides the rehabilitation process into multiple stages, each of which has specific training objectives and contents. This method helps patients gradually restore limb function. Nevertheless, some patients still exhibit poor limb function after standardized exercise. Therefore, a functional evaluation should be performed to analyze the impact of staged functional training after ankle fracture surgery. AIM: To perform a functional evaluation and determine the influencing factors of staged functional training in patients with ankle fracture. METHODS: A retrospective study enrolled 150 patients who underwent surgical treatment for ankle fracture from May 2020 to May 2022 at our hospital. Univariate and multivariate linear regression analyses were performed on general data, functional exercise compliance scale for orthopedic patients, Social Support Rating Scale (SSRS), American Orthopedic Foot and Ankle Score (AOFAS) Ankle-Hindfoot Score, and pain factors [serum bradykinin (BK), prostaglandin E2 (PGE2), 5-hydroxytryptamine (5-HT)]. RESULTS: Based on the AOFAS Ankle-Hindfoot Scale, the cases were divided into the excellent function (n = 111) and ordinary function (n = 39) groups. Univariate analysis revealed that monthly family income, education level, diabetes mellitus, functional exercise compliance scale of orthopedic patients score, SSRS, BK, PGE2, and 5-HT significantly influenced limb function after ankle fracture (P < 0.05); Multiple linear regression analysis showed that the functional exercise compliance scale score, SSRS, BK, PGE2, and 5-HT were independent risk factors affecting functional performance after staged functional exercise (P < 0.05). CONCLUSION: Exercise compliance, SSRS, and pain level are the independent risk factors affecting functional performance after staged functional training following ankle surgery. Clinical nursing care after ankle surgery should include analgesic and health education measures to ensure optimal recovery of limb function.

Staged Bi-compartmental Knee Arthroplasty for Contralateral Compartment Failure After Medial Unicompartmental Knee Arthroplasty in Dialysis Patients: Two Case Reports.

Unicompartmental knee arthroplasty (UKA) is a minimally invasive surgical technique with good clinical outcomes; however, its outcomes in patients undergoing hemodialysis are unknown. Herein, we report two cases of patients undergoing hemodialysis who underwent staged bi-compartmental UKA (Bi-UKA) for early contralateral compartment failure after medial UKA. We describe the case of early contralateral compartment failure after medial UKA in two women patients aged 71 and 72 years with a dialysis history of seven and 22 years, respectively. Three months after right medial UKA, she had persistent joint edema and arthralgia after minor trauma, with recurrent gait disturbance in the first case. An MRI showed a bone marrow lesion in the contralateral compartment, and a lateral UKA was added. In the second case, the knee pain worsened without any trigger three years after leaving the medial UKA. A subchondral insufficiency fracture (SIF) was diagnosed by a plain radiograph showing a radiolucent area on the lateral femoral condyle. Gait disturbance did not improve, and a lateral UKA was performed. In our hospital, medial UKA was performed on seven knees of dialysis patients in 10 years since 2011, and contralateral compartment failure was observed in two knees at an early stage. In both cases, lumbar bone density was normal and there was no postoperative overcorrection in leg alignment, but a SIF of the contralateral side occurred, suggesting that bone fragility of the contralateral compartment due to long-term dialysis was the underlying cause. Staged Bi-UKA was minimally invasive and useful as a revision surgery.

Evaluation of staged autologous blood transfusion during extracorporeal membrane oxygenation decannulation: A retrospective study.

BACKGROUND: Clinical blood resources are scarce and autologous blood transfusion for extracorporeal membrane oxygenation (ECMO) withdrawal is less studied. OBJECTIVES: To assess the use of staged autotransfusion during ECMO decannulation. METHODS: The study included ECMO withdrawal patients. Patients in the autologous transfusion group underwent staged transfusion during ECMO withdrawal, while those in the control group received 2.0 units of allogeneic packed red blood cells (RBCs) to increase hemoglobin (Hb). Parameters such as Hb, hematocrit (Hct), adverse events, decannulation success rate, volume of allogeneic RBC transfusions, and transfusion costs were compared. RESULTS: A total of 82 Chinese patients were enrolled, with a mean age of 46 years, 27 were female, and the top three primary diagnoses were cardiac arrest, acute myocarditis, and severe pneumonia. There were 41 individuals in the autologous blood transfusion group and 41 in the control group. No significant differences were observed in Hb, Hct, adverse events, and the success rate for decannulation between the two groups (all P > 0.05). Compared with the control group, the volume of allogeneic RBC transfusions [0 (0∼1.50) U vs. 3.5 (1.88∼40) U, P < 0.001] and the total cost [130 (130∼390) Chinese Yuan (CNY) vs. 910 (487.50, 1040) CNY, P = 0.002] were lower in the autologous transfusion group. CONCLUSION: In comparison with allogeneic RBC transfusion, staged autotransfusion during ECMO decannulation not only effectively maintained Hb levels but also reduced the requirement for allogeneic RBC transfusions. In addition, this approach decreased the associated costs and did not increase the risk of clinical adverse events.

Nearly 14-Fold Increased Risk of Manipulation Under Anesthesia After Total Knee Arthroplasty When Previous Contralateral Total Knee Arthroplasty Required Manipulation Under Anesthesia.

BACKGROUND: Stiffness remains a common complication after primary total knee arthroplasty (TKA). Manipulation under anesthesia (MUA) is the gold standard treatment for early postoperative stiffness; however, there remains a paucity of data on the risk of MUA after primary TKA if a prior contralateral TKA required MUA. METHODS: We performed a retrospective review of 3,102 patients who had staged primary TKAs between 2016 and 2021. The mean body mass index was 33 (range, 18 to 59) and the mean age was 67 years (range, 24 to 91). The mean preoperative range of motion for the first TKA was 2 to 104°, and for the contralateral TKA was 1 to 107°. The primary outcomes were MUA following first and second primary TKAs. Multivariable Poisson regressions were used to evaluate associations between risk factors and outcomes. RESULTS: The rate of MUA after the first TKA was 2.6% (n = 83 of 3,102) and 1.3% (n = 40 of 3,102) after the contralateral TKA. After adjustment, there was a nearly 14-fold higher rate of MUA after the second TKA if the patient had an MUA after the first TKA (relative risk, 13.80; 95% CI [confidence interval], 7.14 to 26.66). For the first TKA, increasing age (adjusted risk ratio [ARR], 0.65; 95% CI, 0.50 to 0.83) and increasing body mass index (ARR, 0.65; 95% CI, 0.47 to 0.90) were associated with lower risk for MUA. For the second TKA, increasing age was associated with a lower risk of MUA (ARR, 0.60; 95% CI, 0.45 to 0.80). CONCLUSIONS: For patients undergoing staged bilateral TKA, patients who undergo MUA following the first primary TKA are nearly 14-fold more likely to undergo an MUA following the contralateral primary TKA than those who did not have an MUA after their first TKA.

Integrated Laparoscopic Management of Parastomal and Midline Incisional Double Hernias: A Staged Approach Including Hartmann's Reversal and Hernia Repair.

Parastomal hernia (PH) following Hartmann's procedure is a common late-term complication and is often combined with an incisional hernia (IH). The surgical treatment for double hernias with an end colostomy is complex and challenging. We present a 54-year-old woman with an end colostomy and combined hernias (PH and midline IH) after an emergency Hartmann's procedure for diverticular perforation of the sigmoid colon underwent staged surgery. First, laparoscopic Hartmann's reversal (LHR) and PH repair with primary suture were performed. Ten months later, "intraperitoneal onlay mesh repair (IPOM) plus" methods were implemented for IH repair. Both surgeries were successfully conducted using a laparoscopic approach, and no evidence of hernia recurrence has been observed in the 12 months after the second surgery. This case report provides valuable insights into the surgical strategy for double hernias with an end colostomy.

Health Economic Evaluation of Patients With Colorectal Liver Metastases Randomized to ALPPS or TSH: Analysis From the LIGRO Trial.

Objective: This is a preplanned, health economic evaluation from the LIGRO trial. One hundred patients with colorectal liver metastases (CRLM) and standardized future liver remnant <30% were randomized to associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) or two-staged hepatectomy (TSH). Summary Background Data: TSH, is an established method in advanced CRLM. ALPPS has emerged providing improved resection rate and survival. The health care costs and health outcomes, combining health-related quality of life (HRQoL) and survival into quality-adjusted life years (QALYs), of ALPPS and TSH have not previously been evaluated and compared. Methods: Costs and QALYs were compared from treatment start up to 2 years. Costs are estimated from resource use, including all surgical interventions, length of stay after interventions, diagnostic procedures and chemotherapy, and applying Swedish unit costs. QALYs were estimated by combining survival and HRQoL data, the latter being assessed with EQ-5D 3L. Estimated costs and QALYs for each treatment strategy were combined into an incremental cost-effectiveness ratio (ICER). Nonparametric bootstrapping was used to assess the joint distribution of incremental costs and QALYs. Results: The mean cost difference between ALPPS and TSH was 12,662€, [95% confidence interval (CI): -10,728-36,051; P = 0.283]. Corresponding mean difference in life years and QALYs was 0.1296 (95% CI: -0.12-0.38; P = 0.314) and 0.1285 (95% CI: -0.11-0.36; P = 0.28), respectively. The ICER was 93,186 and 92,414 for QALYs and life years as outcomes, respectively. Conclusions: Based on the 2-year data, the cost-effectiveness of ALPPS is uncertain. Further research, exploring cost and health outcomes beyond 2 years is needed.

Two big bones, one big decision: When to fix bilateral femur fractures.

PURPOSE: For polytrauma patients with bilateral femoral shaft fractures (BFSF), there is currently no consensus on the optimal timing of surgery. This study assesses the impact of early (≤ 24 h) versus delayed (>24 h) definitive fixation on clinical outcomes, especially focusing on concomitant versus staged repair. We hypothesized that early definitive fixation leads to lower mortality and morbidity rates. METHODS: The 2017-2020 Trauma Quality Improvement Program was used to identify patients aged ≥16 years with BFSF who underwent definitive fixation. Early definitive fixation (EDF) was defined as fixation of both femoral shaft fractures within 24 h, delayed definitive fixation (DDF) as fixation of both fractures after 24 h, and early staged fixation (ESF) as fixation of one femur within 24 h and the other femur after 24 h. Propensity score matching and multilevel mixed effects regression models were used to compare groups. RESULTS: 1,118 patients were included, of which 62.8% underwent EDF. Following propensity score matching, 279 balanced pairs were formed. EDF was associated with decreased overall morbidity (12.9% vs 22.6%, p = 0.003), lower rate of deep venous thrombosis (2.2% vs 6.5%, p = 0.012), a shorter ICU LOS (5 vs 7 days, p < 0.001) and a shorter hospital LOS (10 vs 15 days, p < 0.001). When compared to DDF, early staged fixation (ESF) was associated with lower rates of ventilator acquired pneumonia (0.0% vs 4.9%, p = 0.007), but a longer ICU LOS (8 vs 6 days, p = 0.004). Using regression analysis, every 24-hour delay to definitive fixation increased the odds of developing complications by 1.05, postoperative LOS by 10 h and total hospital LOS by 27 h. CONCLUSION: Early definitive fixation (≤ 24 h) is preferred over delayed definitive fixation (>24 h) for patients with bilateral femur shaft fractures when accounting for age, sex, injury characteristics, additional fractures and interventions, and hospital level. Although mortality does not differ, overall morbidity and deep venous thrombosis rates, and length of hospital and intensive care unit stay are significantly lower. When early definitive fixation is not possible, early staged repair seems preferable over delayed definitive fixation.
