BACKGROUND: In recent years, the indication for cementless short stem total hip arthroplasty (THA) has been widened to elderly patients as they might profit by the advantages of the short-curved implant design as well. Therefore, this study was conducted to evaluate the clinical and radiological outcome of a cementless short stem in elderly patients (≥ 75 years) compared to a young control group (≤ 60 years).
METHODS: A retrospective cohort of 316 THAs performed between 2014 and 2017 was prospectively examined. In all patients a cementless, curved short stem and press-fit cup (Fitmore® stem; Allofit®/-S cup; both ZimmerBiomet, Warsaw, IN, USA) were implanted via a minimally-invasive anterolateral approach. Clinical and radiological outcome as well as rate of complications and revision were assessed.
RESULTS: In total, 292 patients have been included for analysis of complications and revisions (Øfollow-up: 4.5 years) and 208 patients for clinical and radiological outcome (Øfollow-up: 4.4 years). Complication rate was significantly increased in elderly patients (13.7% vs. 5.8%, p = 0.023), while the revision rate was increased without statistical significance (5.2% vs. 2.2%, p = 0.169). Periprosthetic fractures occurred significantly higher in the elderly patients (5.2% vs. 0.7%; p = 0.026). Both groups showed a comparable clinical outcome in the Harris Hip Score (93.7 vs. 91.9; p = 0.224), Oxford Hip Score (44.5 vs. 43.7; p = 0.350), Forgotten Joint Score (81.7 vs. 81.5; p = 0.952) and WOMAC (7.4 vs. 9.3; p = 0.334).
CONCLUSIONS: Cementless short stem total hip arthroplasty shows a comparable clinical and radiological outcome in patients over 75 years of age compared to younger patients under 60 years of age. However, cementless shorts stem THA shows an increased rate of overall complications and periprosthetic fractures in elderly patients over 75 years of age. Cemented fixation of the femoral component should be considered in patients over 75 years of age.
METHODS: III Case-controlled study.
BACKGROUND: Observational study without need for trial registration due to ICMJE criteria.

OBJECTIVE: Lateral interbody fusion (LIF) is an increasingly popular minimally-invasive spine procedure. This study identifies notable trends in LIF literature and provides a detailed review of the bibliometric aspects of the top 100 most-cited articles.
METHODS: Articles were queried from the Web of Science database. Inclusion criteria consisted of peer-reviewed articles, full-text availability, and LIF focus. Network analysis including co-authorship mapping and bibliographic coupling were complemented by trend analysis to determine prominent contributors and themes. Analyses were conducted using VOSviewer and Bibliometrix (RStudio).
RESULTS: There has been a rapid increase in LIF publication and citation count since 1998. Leading journals were Spine (n = 24), Journal of Neurosurgery Spine (n = 22), and European Spine Journal (n = 12). NuVasive funded the most publications (n = 17), followed by DePuy Synthes Spine (n = 4). The United States was the most represented country (n = 81); however, trend analysis suggests a steadily growing international contribution. The most prolific author was J.S. Uribe (n = 16), followed by a tie in second place by E. Dakwar and L. Pimenta (n = 8). The most frequent keywords, \"complication\" (n = 34), \"surgery\" (n = 30), and \"outcomes\" (n = 24), demonstrated a patient-centric theme.
CONCLUSIONS: This bibliometric analysis provides in-depth insights into the evolution and trends of LIF over the last two decades. The trends and themes identified demonstrate the innovative, collaborative, and patient-focused characteristics of this subfield. Future researchers can use this as a foundation for understanding the past and present state of LIF research while designing investigations.

Avascular necrosis of the femoral head is a debilitating condition that can lead to femoral head collapse. Core decompression with adjuvant cellular therapies, such as bone marrow aspirate concentrate, delays disease progression and improves outcomes. However, inconsistent results in the literature may be due to limitations in surgical technique and difficulty in targeting the necrotic lesions. Here, we present a surgical technique utilizing computed tomography-based three-dimensional modeling and instrument tracking to guide the therapy to the center of the lesion. This method minimizes the number of attempts to reach the lesion and confirms the three-dimensional positioning of the instrumentation within the lesion. Our technique may improve the outcomes of core decompression and adjuvant therapy and prevent or delay hip collapse in patients with femoral head avascular necrosis.

UNASSIGNED: Robot-assisted ventral hernia repair (RVHR) has become a feasible alternative for open ventral hernia repair showing fewer postoperative complications and satisfying short-term results. However, long-term results are scarce in current literature.
UNASSIGNED: All consecutive patients who underwent robot-assisted surgery for ventral hernias from June 2018 until February 2023 were included. Patient records were retrospectively reviewed for indication, need for conversion, length of stay (LOS), postoperative complications, and postoperative pain.In addition, long-term (>24 months) results (recurrence, chronic pain, and esthetic satisfaction) were assessed by phone questionnaire.
UNASSIGNED: In total, 177 patients underwent a robot-assisted ventral hernia repair. Indication for surgery was incisional hernia (N = 109) and primary hernia (N = 68), including 124 cases with abdominal rectus diastasis. A TransAbdominal Retromuscular Umbilical Prosthesis (TARUP) was performed in 138 patients. Robotic Transversus Abdominis Release (TAR) and Extended Totally Extraperitoneal Repair (eTEP) were performed in 20 (11%) and 9 (5%) cases, respectively.Median LOS was 2 days for TARUP and 3.5 days for TAR. Minor complications occurred in 22 patients (16 TARUP, 5 TAR, 1 eTEP). The average pain score on the first postoperative day was 1.8/10. No risk factors for morbidity could be identified by uni- and multivariable analysis.Hernia recurrence developed in four (2%) patients. Chronic pain was reported in two (1%) cases. Seven (4%) patients had esthetic complaints.
UNASSIGNED: Robot-assisted ventral hernia repair is a safe procedure with low postoperative pain and short LOS. Long-term results including recurrence and chronic pain are satisfying.

The field of pediatric organ transplantation has grown significantly in recent decades, with interventional radiology (IR) playing an essential role in managing pre and post-transplant complications. Pediatric transplant patients face unique challenges compared to adults, including donor-recipient size mismatch, and complications of a growing child with changing physiology. Interventional radiologists play a major role in pediatric renal and liver transplant. IR interventions begin early in the child\'s pretransplant journey, with diagnostic procedures such as biopsies, angiograms, and cholangiograms. These procedures are essential for understanding the etiology of organ failure and identifying potential transplant candidates. Minimally invasive therapeutic procedures may serve as bridges to transplant and may include vascular access optimization for hemodialysis, transjugular intrahepatic portosystemic shunts (TIPS) creation, and tumor embolization or ablation. After transplant, image-guided biopsies for the surveillance of graft rejection and treatment of vascular or luminal stenoses, pseudoaneurysms, and anastomotic leaks can maintain the function and longevity of the transplant organ. Careful consideration must be given to patient size and evolving anatomy, radiation exposure, and the need for deeper sedation for pediatric patients. Despite these challenges, the integration of IR in pediatric transplant care has proven beneficial, offering minimally invasive alternatives to surgery, faster recovery times, and improved outcomes.

The advantages of the robotic approach in minimally invasive liver surgery (MILS) are still debated. This study compares the short-term outcomes between laparoscopic (LLR) and robotic (RLR) liver resections in propensity score matched cohorts.
Data regarding minimally invasive liver resections in two liver surgery units were retrospectively reviewed. A propensity score matched analysis (1:1 ratio) identified two groups of patients with similar characteristics. Intra- and post-operative outcomes were then compared. The difficulty of MILS was based on the IWATE criteria.
Two hundred sixty-nine patients underwent MILS between January 2014 and December 2021 (LLR = 192; RLR = 77). Propensity score matching identified 148 cases (LLR = 74; RLR = 74) consisting of compensated cirrhotic patients (100%) underwent non-anatomic resection of IWATE 1-2 class (90.5%) for a solitary tumor < 5 cm in diameter (93.2%). In such patients, RLRs had shorter operative time (227 vs. 250 min, p = 0.002), shorter Pringle\'s cumulative time (12 vs. 28 min, p < 0.0001), and less blood loss (137 vs. 209 cc, p = 0.006) vs. LLRs. Conversion rate was nihil (both groups). In RLRs compared to LLRs, R0 rate (93 vs. 96%, p > 0.71) and major morbidity (4.1 vs. 5.4%, p > 0.999) were similar, without post-operative mortality. Hospital stay was shorter in the robotic group (6.2 vs. 6.6, p = 0.0001).
This study supports the non-inferiority of RLR over LLR. In compensated cirrhotic patients underwent resection of low-to-intermediate difficulty for a solitary nodule < 5 cm, RLR was faster, with less blood loss despite the shorter hilar clamping, and required shorter hospitalization compared to LLR.

Careful preoperative planning is key in minimally invasive radical antegrade modular pancreatosplenectomy (MI-RAMPS). This retrospective study aims to show the practical implications of computed tomography distance between the right margin of the tumor and either the left margin of the spleno-mesenteric confluence (d-SMC) or the gastroduodenal artery (d-GDA). Between January 2011 and June 2022, 48 minimally invasive RAMPS were performed for either pancreatic cancer or malignant intraductal mucinous papillary neoplasms. Two procedures were converted to open surgery (4.3%). Mean tumor size was 31.1 ± 14.7 mm. Mean d-SMC was 21.5 ± 18.5 mm. Mean d-GDA was 41.2 ± 23.2 mm. A vein resection was performed in 10 patients (20.8%) and the pancreatic neck could not be divided by an endoscopic stapler in 19 operations (43.1%). In patients requiring a vein resection, mean d-SMC was 10 mm (1.5-15.5) compared to 18 mm (10-37) in those without vein resection (p = 0.01). The cut-off of d-SMC to perform a vein resection was 17 mm (AUC 0.75). Mean d-GDA was 26 mm (19-39) mm when an endoscopic stapler could not be used to divide the pancreas, and 46 mm (30-65) when the neck of the pancreas was stapled (p = 0.01). The cut-off of d-GDA to safely pass an endoscopic stapler behind the neck of the pancreas was 43 mm (AUC 0.75). Computed tomography d-SMC and d-GDA are key measurements when planning for MI-RAMPS.

UNASSIGNED: To share our surgical experiences of minimally invasive cervical and lumbar procedures for patients who suffered from non-fatal motor vehicle accidents (MVAs) in the ambulatory surgery centers (ASCs) during the coronavirus disease 2019 (COVID-19) pandemic.
UNASSIGNED: Anterior cervical discectomy and fusion (ACDF), anterior lumbar interbody fusion (ALIF), minimally invasive laminotomy and discectomy (MILD), percutaneous endoscopic laser-assisted discectomy (PELD) and percutaneous kyphoplasty (PK) were performed on carefully selected patients.
UNASSIGNED: From January 2020 to December 2021, our group performed 164 cases on 153 patients involving 249 intervertebral disc (IVD) levels. Of these, 116 cases (70.73%) on 114 patients (74.51%) were cervical, 48 cases (29.27%) were lumbar (including 8 PK cases). Eight patients had both cervical and lumbar procedures in a single anesthetic session (SAS) and were discharged on the same day. One hundred and six ACDF cases (92.17%) were at the C4-C5 and C5-C6 levels, which comprised of 146 (76.04%) IVDs. Of the 40 non-PK lumbar cases, 38 (95.0%) were at L4 to S1 lumbar levels. Six of these cases (15.0%) involved 2 lumbar levels. In contrast, 6 out of 8 kyphoplasties (75.0%) involved lower thoracic/higher lumbar vertebral columns (T11 to L2) and 2 were at the lower lumbar L4 level.
UNASSIGNED: We successfully and safely performed various cervical and lumbar spine surgeries in the ASCs amid COVID-19 pandemic and all patients achieved the same-day discharge (SDD). In the non-fatal MVAs, mid-lower cervical (C4 to C6) and lower lumbar (L4 to S1) IVDs were the most affected levels.

BACKGROUND: Robotic surgery and ERAS protocol care are both prominent developments and have each become global trends. However, the effects and learning curves of combining robotic surgery and ERAS care in colorectal resection have not yet been well validated. This study aimed to present our real-world experience and establish the learning curves necessary for the implementation of an ERAS program in minimally-invasive surgery for colorectal resection, while also evaluating the impact that the development of the robotic technique has on ERAS outcomes.
METHODS: A total of 155 patients who received elective, minimally-invasive surgery, including laparoscopic and robotic surgery for colorectal resection, with ERAS care during the period June 2019 to September 2021 were included in this retrospective analysis. Patients were divided chronologically into five groups (31 cases per quintile). Patient demographics, tumor characteristics, perioperative data, ERAS compliance, and surgical outcomes were all compared among the quintiles. Learning curves were evaluated based on ERAS compliance and optimal recovery, which are composed of an absence of major complications, postoperative length of stay (LOS) of no more than five days, and no readmission within 30 days. A multivariable logistic regression model was used to assess factors associated with postoperative LOS.
RESULTS: There were no statistically significant differences seen overall or between the quintile groups in regards to demographic and tumor characteristic parameters. A total of 79 patients (51%) received robotic surgery, with the ratio of robotic groups rising chronologically from zero in the first quintile to 90.3% in the fifth quintile (p < 0.001). The median compliance rate of total ERAS protocol was 83.3% overall, 72.2% in the first quintile and 83.3% in the 2nd-5th quintiles (p < 0.001). A total of 85 patients underwent optimal recovery after surgery, four patients in the first quintile, 11 patients in the second quintile, and 21, 24, 25 patients in the 3rd-5th quintiles respectively (p < 0.001). There were significant improvements from early to later groups upon postoperative LOS (p < 0.001). In addition, the surgical outcomes including first oral intake within 24 hours after surgery, time to first stool and early termination of intravenous fluid administration showed significant improvement among the quintiles. A multivariable logistic regression model demonstrated that robotic surgery was superior to laparoscopic surgery upon postoperative LOS (odds ratio = 5.029, 95% confidence interval [CI] = 1.321 to 19.142; p = 0.018).
CONCLUSIONS: Our experience demonstrated that an effective implementation of the ERAS program in minimally-invasive colorectal surgery requires 31 patients to accomplish the higher compliance and requires more cases to reach the maturation phase for optimal recovery. We believe that developing a robotic platform would have no impact on the learning curve of ERAS implementation. Moreover, there is a beneficial effect on the postoperative length of surgery provided through the combination of ERAS care and robotic surgery for patients undergoing colorectal resection.
