Background/Objectives: The purpose of this review was to determine the impact of osteoporosis on outcomes after surgery for cervical deformity. Cervical deformity involves abnormal curvature or misalignment of the cervical spine, often resulting in a significant loss of quality of life and requiring surgical correction. While osteoporosis has been associated with hardware failure including screw loosening and cage migration in spine surgery, its role in cervical deformity remains unclear. Existing studies report mixed findings with regard to postoperative sequelae in patients with osteoporosis undergoing surgical correction of cervical deformity. Methods: A systematic review using PRISMA guidelines and MeSH terms involving spine surgery for cervical deformity and osteoporosis was performed. The Medline (PubMed) database was searched from 1990 to August 2022 using the following terms: “osteoporosis” AND “cervical” AND (“outcomes” OR “revision” OR “reoperation” OR “complication”). This review focused on radiographic outcomes, as well as post-operative complications. Results: Eight studies were included in the final analysis. Three papers assessed risk factors for the development of post-operative distal junctional kyphosis (DJK), but only one found osteoporosis as a predictor for DJK. Although three studies found that osteoporosis was not significantly associated with the incidence of surgical complications, one highlights osteoporosis as a predictor of complications at 90 days postoperatively (p < 0.001) and another associates osteoporosis with overall poor outcomes (p = 0.021). Furthermore, one study assessing the relationship between osteoporosis and reoperation found no association. Conclusions: Overall, our systematic review suggests that in patients undergoing surgery for cervical deformity, osteoporosis is not predictive of the need for reoperation or the development of postoperative complications, such as DJK, dysphagia, superficial infection, and others. These findings highlight the need for further study regarding the role of osteoporosis in surgical correction of cervical deformity. Full article

Background: Heterotopic ossification (HO) is a frequent radiographic finding after total ankle arthroplasty (TAA), but its clinical relevance, diagnostic criteria, and prognostic implications remain uncertain. This systematic review summarizes current evidence on HO incidence, distribution, severity, risk factors, clinical impact, and diagnostic/prognostic value to inform surgical decision-making regarding approach, implant design, and revision strategies. Methods: A systematic review was conducted according to PRISMA guidelines using PubMed, Web of Science, and Scopus databases and the following search string “heterotopic ossification” AND “ankle” (February 2015–February 2025). Twenty-two studies were included, most of which were retrospective and varied in methodological quality. Data were extracted on HO incidence, severity, clinical relevance, and factors associated with diagnosis and management. Results: HO incidence varied widely across studies. No significant associations were found between HO and surgical variables such as approach (all studies used the anterior approach) or coronal alignment. HO presence did not consistently correlate with reduced postoperative range of motion and radiographic follow-up duration. Implant design appeared to influence anatomical distribution in some comparative studies, though without statistical significance. Reoperations specifically for HO excision were rare and mainly performed for mechanical complications (impingement or osteolysis) rather than HO severity itself. Conclusions: Although HO is a frequent finding after TAA, its clinical impact appears limited and largely unpredictable. Diagnostic tools are currently limited to conventional radiography, and no reliable prognostic markers exist. Further high-quality studies are needed to define standardized diagnostic criteria and clarify the prognostic role of HO in long-term outcomes. Full article

Solitary fibrous tumors (SFTs) of the spine are rare. SFTs, especially those classified as WHO grade II or III (previously termed hemangiopericytomas), are aggressive neoplasms with a high recurrence rate and metastatic potential. In the literature, descriptions of SFTs are limited to case reports and small case series. To our knowledge, 157 cases, including the current case, have been reported since Schirger’s 1958 report on spinal SFTs. This report describes two cases of WHO grade II and III SFTs in the spine and presents a review of the literature. In the first case, an extradural WHO grade II SFT recurred 6 years after the first surgery, and a second surgery was performed, including wide excision of the surrounding tissue. The patient has remained recurrence-free for 16 years since the second surgery. In the second case, an intradural extramedullary WHO grade III SFT was resected, including the dura mater, and the patient has remained recurrence-free for 3 years since the surgery. Few reports have described tumor recurrence and long-term outcomes after reoperation, as in the first case, or extensive resection including the dura, as in the second case. Furthermore, the literature review not only summarizes patients’ general and surgical information, but also indicates, based on multivariate analysis, that gross total resection (GTR) is an important factor in preventing recurrence and metastasis. This is the first study to comprehensively examine previous reports and identify risk factors for recurrence and metastasis. In addition, because recurrences have been reported long after surgery, we believe that even if GTR is performed surgically, it is important to conduct follow-ups to check for long-term recurrence.

Background: Venous congestion is a major contributor to complications in DIEP flap breast reconstruction. Beyond superficial venous dominance, the presence or absence of anatomical connections between the superficial and deep venous systems may influence drainage physiology. This study investigates how preoperative CTA and targeted superdrainage impact outcomes over a 25-year period. Patients and Methods: A retrospective analysis was conducted on 208 DIEP flaps performed from 2000 to 2024 at a single center. From 2006, computed tomographic angiography (CTA) was routinely used to evaluate venous anatomy, focusing on the presence, trajectory, and connection of the superficial inferior epigastric vein (SIEV) with the deep system. Superdrainage was performed when superficial venous dominance was evident or drainage was judged insufficient intraoperatively. Primary outcomes included venous congestion, partial necrosis, and reoperations; secondary outcomes included hospital stay and safety of superdrainage. Results: Venous complications decreased significantly after CTA implementation (37.5% vs. 8.0%; p < 0.001). Superdrainage was performed in 40.9% of post-CTA cases, with 90% preoperatively planned based on CTA findings. No complications were associated with second venous anastomosis. Flap outcomes correlated not with perforator number or flap size but with venous drainage physiology. Mean hospital stay was shorter post-CTA (6 vs. 9 days; p < 0.001). Conclusions: Evaluating the anatomical connection between superficial and deep venous systems via CTA enhances venous planning and allows for safer, physiology-driven decisions. In the absence of such connections, intraoperative evaluation remains essential. Drainage physiology—rather than anatomical metrics alone—should guide surgical strategy in DIEP flap reconstruction.

Post-operative pancreatic fistula (POPF) is a serious yet far too common complication following distal pancreatectomy (DP), as it affects 20–30% of patients after DP. POPF raises the risk of other complications and causes delays to a patient’s oncologic care. In this review, we present the latest data on patient risk factors for developing POPF, such as obesity, smoking, young age, thick pancreas, lack of epidural anesthesia, hypoalbuminemia, and elevated drain amylase levels. Other risk factors that have been identified with irregular consistency include open surgical approach, non-malignant or neuroendocrine tumor pathology, simultaneous splenectomy, simultaneous vascular resection, and long operative time. We also review the consequences of POPF, which include hemorrhage, infection, delayed gastric emptying, re-operation, re-admission, delays in adjuvant chemotherapy initiation, reduced progression-free survival, and reduced overall survival. Finally, we present strategies that have been studied for avoiding POPF after DP, including reducing pressure at the sphincter of Oddi, the use of sealants and patches, optimizing pancreatic transection, strategies for post-operative drain placement, the use of post-operative somatostatin analogues, and pre-clinical studies of experimental devices and techniques that may inform future trials. This review informs readers on the current state of the art with regard to POPF after DP and sets the stage for future studies to improve patient outcomes. Full article

Background: The guidelines recommend mitral valve repair whenever possible in patients undergoing surgical treatment for active infective endocarditis of the native mitral valve. However, the impact of causative microorganisms in relation to treatment strategies, especially Staphylococcus aureus, has not been studied. In this study, we aimed to compare the outcomes of mitral valve repair versus replacement in patients with native mitral valve infective endocarditis caused by methicillin-susceptible Staphylococcus aureus. Methods: Consecutive patients with definitive active infective endocarditis of the native mitral valve caused by methicillin-susceptible Staphylococcus aureus undergoing cardiac surgery between 2012 and 2022 were selected. Patients were classified according to the treatment received in two groups: repair and replacement. Inverse propensity treatment weighting was employed to correct for confounders. The endpoints were all-cause mortality, incidence of recurrent endocarditis, reoperation rate, and event-free survival at two-year follow-up. Results: Among 170 operated-upon patients with active infective endocarditis of the native mitral valve, 44 cases were caused by methicillin-susceptible Staphylococcus aureus. A total of 23 patients underwent mitral valve repair and 21 patients received mitral valve replacement. Weighted 30-day mortality in the repair group was 43%, versus 27% in the replacement group (p = 0.15). Two-year mortality increased to 57% in the repair group and 32% in the replacement group (p = 0.02). Three patients developed recurrent endocarditis in the repair group, while no recurrent endocarditis occurred in the replacement group. Three patients in the repair group required reoperation due to recurrence and one patient in the replacement group underwent re-operation due to paravalvular leakage. Weighted two-year event-free survival was 29% in the repair group and 59% in the replacement group (p < 0.01). Conclusions: Mortality in patients with mitral valve infective endocarditis caused by Staphylococcus aureus is extremely high, especially in patients undergoing mitral valve repair. The risk of recurrent endocarditis and mid-term mortality seems to be higher in mitral valve repair, resulting in poor event-free survival during two-year follow-up. However, the sample size was likely insufficient for drawing definitive conclusions. Full article

Prosthetic joint infections (PJIs) pose significant challenges, often requiring multiple surgeries that lead to soft tissue loss, dead space, and fibrosis. Wound breakdown increases the risk of polymicrobial infection and treatment failure. The vertical rectus abdominis myocutaneous (VRAM) flap is a proven method for complex wound coverage, but its role in managing hip PJI is underexplored. This study evaluates outcomes of VRAM flap reconstruction in polymicrobial hip PJI. We retrospectively reviewed five patients who underwent VRAM flap reconstruction for polymicrobial hip PJI between December 2020 and December 2023. Primary outcomes included flap survival, infection control, and wound healing. Secondary outcomes were implant retention, postoperative complications, and functional status. At a mean follow-up of 28 months, four patients achieved wound healing and remained infection-free, while one had persistent sinus drainage but retained the implant. Flap survival was 100%, with no necrosis or failure. No major complications requiring reoperation occurred. Two patients developed deep collections, managed with ultrasound-guided drainage (Clavien-Dindo IIIa). Minor complications included donor-site dehiscence (three), flap dehiscence (one), edge necrosis (two), and hernias (two), all managed non-surgically (Clavien-Dindo I/II). All patients retained implants and remained ambulatory. VRAM flap reconstruction is a reliable option for managing complex polymicrobial hip PJI. Flap survival was excellent, and most patients achieved infection control. However, persistent infection and the need for suppressive antibiotics highlight the ongoing challenges in these cases.

Objectives: To examine the rate of meniscal re-tear in patients with concomitant ACL reconstruction, with specific focus on surgical factors and patient demographic factors. Methods: A retrospective chart review was performed on all patients who underwent meniscal repair with concomitant ACL reconstruction at our institution over a seven-year period. Demographic and case variables were assessed, including sex, age, height, weight, BMI, medial versus lateral repairs, ACL graft type, ACL reconstruction technique, meniscus repair technique, and post-operative weight bearing status. Failure of repair was defined as need for repeat surgery on the same meniscus. Results: There were 191 patients included in the study; of those 118 did not need further surgery on the meniscus at a minimum of 2 years post operation while 73 did have a re-operation on the same meniscus (rate of failure 38.2%). There were significant differences between re-operation and non-re-operation groups based on ACL graft type (54% failure for allograft vs. 30/23% failure for both autograft cohorts) and meniscal repair side (46% re-tear rate for medial meniscus vs. 17% for lateral meniscus). The pediatric (under 18 years old) cohort included 57 patients; 28 patients required additional meniscal surgery and 29 did not (rate of re-operation 49%). Conclusions: The overall failure rate of meniscus repair was nearly 40%. Risk factors for re-tear of the meniscus were repair of the medial meniscus and allograft usage for ACL reconstruction. The rate of re-tear in patients under 18 was nearly 50%, which is higher than in the adult population. Full article

Background/Objectives: We compared short- and long-term outcomes of patients with native left-sided infective endocarditis (IE) confined to the valve leaflet (“simple”) versus those with perivalvular extension (“complex”) over two decades. Methods: From 2005 to 2024, 177 patients (mean age 59.6 ± 13.8 years, 71.8% male) underwent surgery for IE. Patients were classified as having simple (n = 129) or complex IE (n = 48) based on imaging and intraoperative findings. Mean follow-up was 86.5 ± 63.3 months (range: 2–232 months). Outcomes included operative and late mortality, recurrent infection, and reoperation. Results: Complex IE was associated with worse preoperative status, longer ICU stays, and mechanical ventilation times. Predictors of early mortality included critical preoperative state (OR 6.35, p = 0.001), chronic renal failure/dialysis (OR 3.01, p = 0.05), and staphylococcal IE (OR 5.62, p = 0.002) but not perivalvular extension. Overall survival at 1, 5, 10, 15, and 20 years was 83%, 74.2%, 59.9%, 51.3%, and 40.7%, with no significant difference between groups (p = 0.18). Female gender (HR 1.93, p = 0.04) and chronic renal failure (HR 3.5, p < 0.01) predicted late mortality. Freedom from re-endocarditis and reoperation d/t relapse of endocarditis was 94.2% and 97.3%, respectively. Freedom from re-intervention d/t structural valve degeneration was 92.1% at 10 years. Repair was performed in 28.2% of cases involving the mitral valve, with 93.1% freedom from reoperation. Conclusions: Surgery for complex IE is not an independent risk factor for long-term mortality. Rates of recurrent endocarditis and reoperation are remarkably low. Excellent durability of bioprostheses and mitral repair was demonstrated. Full article

Background: Accurate preoperative tumor sizing is critical for optimal surgical planning in breast cancer. Contrast-enhanced mammography (CEM) has emerged as a promising modality, yet its accuracy relative to conventional imaging and pathology requires further validation. Objective: To prospectively evaluate the dimensional accuracy and reproducibility of CEM compared to mammography and ultrasound, using surgical pathology as the reference standard. Methods: A total of 205 patients with 267 breast lesions underwent preoperative CEM, mammography, and ultrasound. Tumor sizes were measured independently by two radiologists. Accuracy was assessed via mean absolute error (MAE), Pearson and Spearman correlations, and inter-reader agreement evaluated by intraclass correlation coefficient (ICC) and Gwet’s AC1. Sensitivity analyses included bootstrap confidence intervals and log-transformed data. The surgical impact of additional lesions detected by CEM was also analyzed. Results: CEM showed superior accuracy with a mean absolute error of 0.46 mm (95% CI: 0.24–0.68) compared to mammography (4.06 mm) and ultrasound (3.52 mm) (p < 0.00001). Pearson’s correlation between CEM and pathology was exceptionally high (r = 0.995; 95% CI: 0.994–0.996), with similar robustness after log transformation. Inter-reader agreement for CEM was excellent (ICC 0.93; Gwet’s AC1 ~0.96, 95% CI: 0.93–0.98). CEM detected additional lesions in 13.1% of patients, leading to altered surgical management in 6.4%. Background parenchymal enhancement was independently associated with measurement error. Conclusions: CEM provides highly accurate and reproducible tumor size estimation superior to conventional imaging modalities, with potential clinical impact through detection of additional lesions. Its ability to detect additional lesions not seen on mammography or ultrasound has direct implications for surgical decision making, with the potential to reduce reoperations and improve oncologic and cosmetic outcomes. However, high correlation values and selective patient cohorts warrant cautious interpretation. Further multicenter studies are needed to confirm these findings and define CEM’s role in clinical practice. Full article

Background: Re-excision after breast-conserving surgery (BCS) is routinely recommended when positive margins are found. However, secondary surgery often reveals no residual disease, exposing patients to unnecessary interventions that compromise cosmetic outcomes, increase costs, and reduce quality of life. This study investigates clinicopathological predictors of a residual tumour to identify low-risk patients who may safely avoid re-excision. Methods: We conducted a retrospective cohort study of 135 patients who underwent reoperation for positive margins following BCS at the Breast Unit of Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome, between 2019 and 2024. Data on patient demographics, tumour characteristics, and histopathological findings were analyzed using univariate and multivariate models to identify predictors of residual disease. Results: A residual tumour was detected in 66 of 135 patients (48.9%). In the remaining 69 cases (51.1%), no residual disease was found, indicating that re-excision may have been unnecessary. Multifocality (p < 0.01), lymphovascular invasion (LVI) (p < 0.05), and involvement of ≥2 margins (p < 0.05) were independently associated with the residual tumour. Patients with unifocal disease, absence of LVI, and a single positive margin had a significantly lower risk of residual disease. Conclusions: Over half of re-excisions performed for positive margins may be avoidable. A risk-adapted approach incorporating tumour focality, LVI status, and margin involvement can help identify patients for whom secondary surgery may offer limited benefits. These findings support a more individualized strategy to margin management in BCS aimed at reducing overtreatment without compromising oncologic safety. Full article

Background/Objectives: Lower urinary tract symptoms (LUTSs) due to benign prostatic obstruction (BPO) represent a common condition affecting aging men. Transurethral resection of the prostate represents the gold standard surgical treatment but is not without complications such as retrograde ejaculation, bleeding and urinary retention. The temporary implantable nitinol device (iTIND) is considered a minimally invasive surgical technique, designed to treat LUTS while preserving erectile and ejaculatory function. Herein we report the results of a multi-center, real-world assessment of the iTIND procedure. Methods: Data from five international centers treating LUTS with the iTIND device were collected. We recorded changes through an International Prostatic Symptom Score (IPSS) questionnaire with Quality of Life (QoL), International Index of Erectile Function (IIEF5) questionnaire, antegrade ejaculatory function, maximum flow (QMax), post voiding residual volume (PVR) and freedom from repeat intervention. Results: A total of 74 subjects were enrolled; median follow-up was 12 months. IPSS and QoL changed from a median of 23 and 4 points at baseline to 11 and 2 points, respectively, at the last follow-up. A mean improvement in Qmax and PVR from 9 mL/s and 56 mL at baseline to 13 mL/s and 40 mL was noticed at the last follow-up. Total median operative time was 10 min, and the median time of iTIND indwell time was 7 days. The median device removal time was 5 min. There were no changes in IIEF5 scores and antegrade ejaculation rate. No intraoperative complications were reported, and non-serious postoperative complications occurred in six patients (two urinary retention, two mild haematuria, two urinary tract infection). Finally, four patients underwent reoperation during the follow-up period. All procedures were performed as outpatient day cases. Conclusions: Our results confirms that treatment with the iTIND is effective and safe in terms of improving urinary symptoms and quality of life without impacting sexual function. Longer follow-up is required to better define the durability of this minimally invasive procedure. Full article

Objectives: The objective of this study was to evaluate the safety of postoperative in vitro fertilization (IVF) for atypical endometriosis (AE) in terms of ovarian endometrioma recurrence and development of endometriosis-related ovarian cancer (EAOC). Methods: Premenopausal women with AE who had undergone ovarian surgery between 2008 and 2022 and had attended follow-up appointments for at least 3 months were included in this retrospective study. The recurrence of endometriosis, postoperative pregnancy rate, occurrence of postoperative EAOC in cases of AE, and independent risk factors of AE recurrence were analyzed. Results: A total of 105 patients were included in the study with a median age of 33 years (range, 16–50 years) and a median follow-up duration of 29.0 months (range, 3–143 months). Most of the patients were treated with cyst enucleation (96.2%). Recurrent ovarian endometrioma was detected in 19 patients (18.1%), 4 of whom (19.0%) underwent reoperation, and there were no cases of EAOC. The cumulative recurrence rate at 12, 24, and 50 months was 7.4, 15.8, and 26.3%, respectively. Among the 105 patients, 36 wanted to become pregnant; of these, 12 underwent IVF, which, according to a univariable analysis, did not increase their risk of recurrent ovarian endometrioma. According to a subsequent multivariable analysis, previous history of ovarian endometrioma operation was the sole significant risk factor for AE recurrence (HR, 4.246; 95% CI, 1.262–14.285; p = 0.020). Conclusions: IVF trials for pregnancy did not represent a risk factor for recurrence, as treated AE showed a low possibility of malignant transformation, and IVF was not a risk factor for recurrence.

Background/Objectives: Anterior redisplacement, defined as a postoperative anterior shift of the distal fragment despite intraoperative reduction, is occasionally observed after cephalomedullary nailing for trochanteric femoral fractures. However, its incidence and associated risk factors remain unclear. This study aimed to determine the incidence of anterior redisplacement following intramedullary nail fixation in geriatric trochanteric fractures, and to identify independent risk factors. Methods: This study retrospectively reviewed data from 598 consecutive hips in 577 patients (aged ≥65 years) who underwent intramedullary nail fixation for trochanteric fractures at a single center (2012–2023). Sagittal reduction on the lateral radiographic view was classified as posterior, anatomical, or anterior according to the position of the distal fragment, and was recorded preoperatively and postoperatively. Anterior redisplacement, the primary outcome, was defined as a change in alignment from a posterior or anatomical position postoperatively to an anterior position on any subsequent follow-up radiograph. Independent risk factors were identified by logistic regression. Results: Among the 543 hips reduced posteriorly (n = 204) or anatomically (n = 339), anterior redisplacement occurred in 73 (13.4%). The incidence of anterior redisplacement was significantly higher following anatomical compared to posterior reduction (19.5% vs. 3.4%; p < 0.001), and also higher in fractures that were anteriorly aligned preoperatively (18.0%) compared to anatomical (8.5%; p < 0.01) and posterior (6.2%; p < 0.01) alignment. Multivariate analysis revealed two independent predictors: preoperative anterior alignment (odds ratio [OR] 1.87, 95% confidence interval [CI] 1.24–2.81; p = 0.003) and postoperative anatomical (vs. posterior) reduction (OR 6.49, 95% CI 2.92–14.44; p < 0.001). Age, sex, Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association classification, Evans–Jensen classification, nail length, and canal-filling ratio were not associated with redisplacement. No lag-screw cutout occurred during the follow-up. Conclusions: Anterior redisplacement occurred in one of seven geriatric trochanteric fractures despite apparently satisfactory fixation. An anatomical sagittal reduction—traditionally considered “ideal”—increases the risk more than sixfold, whereas a deliberate posterior-buttress is protective. Unlike patient-related risk factors, sagittal reduction is under the surgeon’s control. The study findings provide evidence that choosing a slight posterior bias can significantly improve stability.

Background: In high-risk and frail patients with multivessel coronary artery disease (MV CAD), guidelines indicated complete revascularization with or without the use of cardiopulmonary bypass (CPB) bears a high morbidity and mortality risk. In cases where catheter interventions were deemed unsuitable and conventional coronary artery bypass grafting (CABG) posed an unacceptable perioperative risk, patients were scheduled for minimally invasive direct coronary artery bypass (MIDCAB) grafting or minimally invasive multivessel coronary artery bypass grafting (MICS-CABG). We called this approach “palliative revascularization.” This study assesses the safety and impact of palliative revascularization on clinical outcomes and overall survival. Methods: A consecutive series of 57 patients undergoing MIDCAB or MICS-CABG as a palliative surgery between 2008 and 2018 was included. The decision for palliative surgery was met in heart team after carefully assessing each case. The patients underwent single or double-vessel revascularization using the left internal thoracic artery and rarely radial artery/saphenous vein segments, both endoscopically harvested. Inpatient data could be completed for all 57 patients. The mean follow-up interval was 4.2 ± 3.7 years, with a follow-up rate of 91.2%. Results: Mean patient age was 79.7 ± 7.4 years. Overall, 46 patients (80.7%) were male, 26 (45.6%) had a history of atrial fibrillation and 25 (43.9%) of chronic kidney disease. In total, 13 patients exhibited a moderate EuroSCORE II, while 27 were classified as high risk, with a EuroSCORE II exceeding 5%. Additionally, 40 patients (70.2%) presented with three-vessel disease, 17 (29.8%) suffered an acute myocardial infarction within three weeks prior to surgery and 50.9% presented an impaired ejection fraction. There were 48 MIDCAB and nine MICS CABG with no conversions either to sternotomy or to CPB. Eight cases were planned as hybrid procedures and only 15 patients (26.3%) were completely revascularized. During the first 30 days, four patients (7%) died. A myocardial infarction occurred in only one case, no patient necessitated immediate reoperation. The one-, three- and five-year survival rates were 83%, 67% and 61%, respectively. Conclusions: MIDCAB and MICS CABG can be successfully conducted as less invasive palliative surgery in high-risk multimorbid patients with MV CAD. The early and mid-term results were better than predicted. A higher rate of hybrid procedures could improve long-term outcome in selected cases. Full article
