Background: Pelvic fractures are complex injuries often associated with significant morbidity and mortality, requiring multidisciplinary management. This case series highlights the presentation, management strategies, and outcomes of patients with pelvic fractures treated at our institution. Methods: The medical records of 13 patients diagnosed with pelvic fractures from 1 January 2020 through 31 December 2023 were retrospectively reviewed. Demographic data, mechanism of injury, fracture pattern, associated injuries, treatment modalities, and outcomes were analyzed. Results: A total of 13 patients were included in the study, with ages ranging from 18–95 years. Six of the patients were male and seven were female. The most common mechanisms of injury were falls and pedestrians struck by vehicles. Associated injuries included traumatic brain injury (TBI), fractures including extremities, ribs, and vertebrae, visceral injury, and spinal cord injury. Treatment strategies ranged from conservative, non-surgical management to operative intervention, including interventional radiology embolization, external traction, open reduction and internal fixation (ORIF), and percutaneous screw stabilization. Additional interventions included chest tube placement, exploratory laparotomy, and craniectomy. Two patients died while in the hospital, one was discharged to a shelter, and the remaining 10 were discharged to various inpatient rehab facilities. Conclusions: Pelvic fractures pose significant clinical challenges due to their complexity and associated injuries. This case series underscores the importance of multidisciplinary intervention and treatment strategies in optimizing outcomes. Further studies should focus on the effectiveness of interventions, utilization of new technology, and multidisciplinary team planning. Full article

Prostate cancer (PCa) is the second most frequently diagnosed malignancy in men worldwide. Although traditionally considered a disease of older men, the incidence of early-onset PCa (diagnosis < 55 years) is steadily rising. Advances in screening and therapy have significantly improved survival, creating a growing cohort of younger survivors for whom post-treatment quality of life—notably reproductive function—is paramount. Curative treatments such as radical prostatectomy, pelvic radiotherapy, androgen-deprivation therapy (ADT), and chemotherapy often cause irreversible infertility via multiple mechanisms, including surgical disruption of the ejaculatory tract, endocrine suppression of spermatogenesis, direct gonadotoxic injury to the testes, and oxidative sperm DNA damage. Despite these risks, fertility preservation is frequently overlooked in pre-treatment counseling, leaving many patients unaware of their options. This narrative review synthesizes current evidence on how PCa therapies impact male fertility, elucidates the molecular and physiological mechanisms of iatrogenic infertility, and evaluates both established and emerging strategies for fertility preservation and restoration. Key interventions covered include sperm cryopreservation, microsurgical testicular sperm extraction (TESE), and assisted reproductive technologies (ART). Psychosocial factors influencing decision-making, novel biomarkers predictive of post-treatment spermatogenic recovery, and long-term offspring outcomes are also examined. The review underscores the urgent need for timely, multidisciplinary fertility consultation as a routine component of PCa care. As PCa increasingly affects men in their reproductive years, proactively integrating preservation into standard oncologic practice should become a standard survivorship priority. Full article

Introduction: Hip abductor strength is essential for pelvic stability, lower limb alignment, and injury prevention. Weaknesses of the gluteus medius and minimus contribute to various musculoskeletal conditions. Lateral band walks and monster walks are elastic resistance exercises commonly used to target the hip abductors and external rotators in functional, weight-bearing tasks. Therefore, the aim was to summarize the current evidence on the biomechanics, muscle activation, and clinical applications of lateral and monster band walks. Methods: This narrative review was conducted following the SANRA guideline. A comprehensive literature search was performed across PubMed, Scopus, Web of Science, and SPORTDiscus up to April 2025. Studies on the biomechanics, electromyography, and clinical applications of lateral band walks and monster walks were included, alongside relevant evidence on hip abductor strengthening. Results: A total of 13 studies were included in the review, of which 4 specifically investigated lateral band walk and/or monster walk exercises. Lateral and monster walks elicit moderate to high activation of the gluteus medius and maximus, especially when performed with the band at the ankles or forefeet and in a semi-squat posture. This technique minimizes compensation from the tensor fasciae latae and promotes selective gluteal recruitment. Proper execution requires control of the trunk and pelvis, optimal squat depth, and consistent band tension. Anatomical factors (e.g., femoral torsion), sex differences, and postural variations may influence movement quality and necessitate tailored instruction. Full article

Background: Physical exercise during pregnancy is strongly recommended due to its well-established benefits for both mother and child. However, its impact on the pelvic floor remains insufficiently studied. This study aimed to evaluate pelvic floor adaptations to a structured prenatal exercise program using transperineal ultrasound, and to assess associations with the duration of the second stage of labor and mode of delivery. Methods: This is a planned secondary analysis of a randomized controlled clinical trial (RCT) (NCT04563065) including women with singleton pregnancies at 12–14 weeks of gestation. Participants were randomized to either an exercise group, which followed a supervised physical exercise program three times per week, or a control group, which received standard antenatal care. Transperineal ultrasound was used at the second trimester of pregnancy and six months postpartum to measure urogenital hiatus dimensions at rest, during maximal pelvic floor contraction, and during the Valsalva maneuver, to calculate hiatal contractility and distensibility and to evaluate levator ani muscle insertion. Regression analyses were performed to assess the relationship between urogenital hiatus measurements and both duration of the second stage of labor and mode of delivery. Results: A total of 78 participants were included in the final analysis: 41 in the control group and 37 in the exercise group. The anteroposterior diameter of the urogenital hiatus at rest was significantly smaller in the exercise group compared to controls (4.60 mm [SD 0.62] vs. 4.91 mm [SD 0.76]; p = 0.049). No other statistically significant differences were observed in static measurements. However, contractility was significantly reduced in the exercise group for both the latero-lateral diameter (8.54% vs. 4.04%; p = 0.012) and hiatus area (20.15% vs. 12.55%; p = 0.020). Distensibility was similar between groups. There were no significant differences in the duration of the second stage of labor or mode of delivery. Six months after delivery, there was an absolute risk reduction of 32.5% of levator ani muscle avulsion in the exercise group compared to the control group (53.3% and 20.8%, respectively; p = 0.009). Conclusions: A supervised exercise program during pregnancy appears to modify pelvic floor morphology and function, reducing the incidence of levator ani muscle avulsion without affecting the type or duration of delivery. These findings support the safety and potential protective role of prenatal exercise in maintaining pelvic floor integrity. Full article

Iatrogenic urinary tract injury is a known complication of pelvic surgery, most commonly occurring during gynecological procedures. The bladder and ureters are particularly vulnerable due to their close anatomical proximity to the uterus. Urinary tract damage can result from various mechanisms, including laceration, ligation, and thermal injury. Incidence rates vary according to the affected organ and surgical type; bladder injuries occur in 0.24% of benign and 0.4–3.7% of oncologic surgeries, whereas ureteral injuries are reported in 0.08% of benign and 0.39–1.1% of oncologic procedures. Timely diagnosis is essential for effective management. When detected intraoperatively, the injury can often be repaired immediately. Surgical treatment options vary depending on the specific nature and location of the bladder or ureteral damage. Delayed diagnosis can significantly impact the patient’s quality of life, increasing the risk of severe complications such as genitourinary fistulas. This narrative review aims to summarize current evidence on the diagnosis, prevention, and treatment of urinary tract injuries occurring during gynecological surgery. It evaluates risk factors, incidence, management, complications, and prevention strategies for iatrogenic bladder and ureteral injuries. Additionally, it highlights the innovative role of artificial intelligence in preventing urologic damage during gynecological procedures. The relevant literature was identified through a structured search of the PubMed database using predefined keywords related to gynecological surgery and urinary tract injury. Full article

Background: Iatrogenic nerve injuries (NIs) are an under-recognized complication of urological surgery. Though less common than vascular or organ damage, they may cause lasting sensory and motor deficits, significantly affecting patients’ quality of life. With increasing complexity in pelvic procedures, a consolidated understanding of nerve injuries is essential. Purpose: This review aims to synthesize current knowledge regarding peripheral and autonomic NIs in urological surgery, highlighting mechanisms of injury, associated procedures, preventative strategies, and treatment options. Scope: Focused on common urological interventions such as radical prostatectomy, cystectomy, pelvic lymphadenectomy, and reconstructive techniques, the review explores injuries from positional compression, traction, and intraoperative transection to their surgical management. Key Findings: The review categorizes nerve injuries into crush and transection types and details intraoperative signs and repair techniques. Skeletonization of nerves, avoidance of energy devices near neural structures, and prompt end-to-end anastomosis using 7-0 polypropylene are central to management. Adoption of novel sutureless nerve coaptation devices have also been described with promising outcomes. Early repair offers a better prognosis. New intraoperative technologies like NeuroSAFE during robotic-assisted procedures may enhance nerve preservation. Conclusion: Iatrogenic NIs, although rare, are clinically significant and often preventable. Prompt intraoperative recognition and repair are critical. Further research is warranted to develop standardized preventative protocols and enhance intraoperative nerve monitoring. A multidisciplinary approach, extended across surgical specialties, could improve outcomes and guide timely treatment of nerve injuries. Full article

Background: Pelvic ring fractures are a significant and growing health problem in the field of trauma and orthopedic surgery. The aim of this paper was to present a concise description of these musculoskeletal injuries, available classification systems, and vascular and genitourinary complications. Results: The most common complications of serious pelvic ring fractures are arterial and venous hemorrhages, as well as urethral injuries. Arterial hemorrhages most often originate from the trunk or branches of the iliac artery, and the standard treatment is pelvic stabilization and implementation of intravascular procedures. In the case of venous hemorrhages, peritoneal pelvic packing is the most important. Conclusions: A multi-disciplinary approach and treatment algorithmization are important to facilitate the prioritization of therapeutic procedures. Treatment of patients with pelvic ring fractures should take place in specialized trauma centers. Full article

Wheelchair basketball (WB) grants important benefits for people with disabilities but also presents a relevant risk of injury. Wheelchair straps are restraint devices that can improve safety and performance, but limited research has explored their use in WB. This study aims to analyze the use of different types of straps among professional WB players, according to classification score. A cross-sectional study was conducted through an online survey. Participants were divided into two groups based on classification score: low-point players (LPPs; 1.0–2.5), who have greater physical impairment, and high-point players (HPPs; 3.0–4.5), who have lower physical impairment. A total of 82 WB players participated (43 LPPs; 39 HPPs). The Chi-squared test was used to compare variables between groups. Significant differences emerged: chest (p = 0.036), abdominal (p = 0.036), and foot (p = 0.016) straps were more frequently used by LPPs, while thigh (p = 0.020) and leg (p = 0.050) straps were more common among HPPs. No significant difference was found for pelvic strap. Straps used in WB vary with classification score, reflecting the influence of functional ability. These findings offer insights into individualized wheelchair setup and classification procedures. Further studies are needed to expand knowledge on this topic. Full article

Introduction and Objectives: Bladder injuries are broadly classified based on anatomical location into two main categories: extraperitoneal and intraperitoneal. Traditionally, clinicians manage most extraperitoneal bladder ruptures conservatively with catheter drainage, while intraperitoneal ruptures are surgically repaired. This study aims to evaluate the feasibility of conservative management of intraperitoneal bladder rupture in the largest series to date. Methods: A retrospective review was performed of patients treated for intraperitoneal bladder perforations at two large tertiary care centers from 2015 to 2023. The charts of 290 patients with intraperitoneal perforations were reviewed to compile a list of those who underwent initial conservative management of their rupture via Foley catheter, of which there were 16. Demographic data was collected as well as variables related to patient characteristics, computed tomography (CT) measured size of perforation, management, complications, and follow-up. Data were analyzed using descriptive statistics, and comparative analyses (t-test and Fisher’s exact test) were performed. Results: Our final analysis identified 16 patients with intraperitoneal bladder rupture treated with initial conservative management. Of these patients, 15 (94%) were successfully managed with Foley catheter placement. Four patients (25%) experienced complications after conservative management, which included long-term urinary incontinence/retention, urinary tract infection (UTI), and pelvic abscess. For patients successfully managed conservatively, the median duration of catheterization was 18 days (IQR 21.75). Conclusions: For patients with small intraperitoneal bladder ruptures, conservative management with prolonged Foley catheterization is a suitable and successful strategy. Future studies evaluating outcomes in larger cohorts of patients will help determine whether this strategy should be considered more frequently in select patient populations. Full article

Background and Clinical Significance: Robotic surgery reduces the need for extensive surgical approaches and lowers perioperative complications. In particular, it offers enhanced dexterity, three-dimensional visualization, and improved precision in confined anatomical spaces. Pelvic masses pose significant challenges due to their close relationship with critical neurovascular structures, making traditional open or laparoscopic approaches more invasive and potentially riskier. Robot-assisted resection, combined with intraoperative neurophysiological monitoring, may therefore offer a safe and effective solution for the management of complex pelvic lesions. Case Presentation: An 18-year-old woman was incidentally diagnosed with an 11 cm asymptomatic pelvic mass located anterior to the sacrum. Initial differential diagnoses included neurofibroma, teratoma, and myelolipoma. Histopathological examination confirmed a ganglioneuroma. Following multidisciplinary discussion, the patient underwent a robot-assisted en bloc resection using the Da Vinci Xi multiport system. Preoperative planning was aided by 3D modeling and intraoperative navigation. Conclusions: Surgery lasted 322 min. Preoperative and postoperative eGFR values were 145.2 mL/min and 144.0 mL/min, respectively. The lesion measured 11 cm × 9 cm × 8 cm. The main intraoperative complication was a controlled breach of the iliac vein due to its close adherence to the mass. No major postoperative complications occurred (Clavien-Dindo Grade I). The drain was removed on postoperative day 3, and the bladder catheter on day 2. The patient was discharged on postoperative day 5 without further complications. Presacral ganglioneuromas are rare neoplasms in a surgically complex area. A multidisciplinary approach using robotic-assisted laparoscopy with nerve monitoring enables safe, minimally invasive resection. This strategy may help avoid open surgery and reduce the risk of neurological and vascular injury. Full article

Background/Objective: Iatrogenic ureteral injury is a rare but serious complication of colorectal cancer surgery. Although prophylactic ureteral catheterization (PUC) is used to facilitate intraoperative ureter identification and reduce the risk of ureteral injury, its efficacy is debated. We aimed to evaluate the clinical utility and outcomes of PUC in colorectal cancer surgery. Methods: This retrospective study included 42 patients who underwent PUC before colorectal cancer surgery at the Tohoku University Hospital between February 2010 and September 2024. Preoperative ureteral stents were inserted via cystoscopy under general anesthesia. Patient demographics, surgical techniques, indications for catheterization, and post-procedural complications were reviewed. Results: PUC was most frequently performed in patients with left-sided colorectal cancer (61.9%) and local recurrence of rectal cancer (31%). Ureteral catheterization was indicated in patients with a history of pelvic surgery (47.6%) or tumor proximity to the ureter (26.2%). Open surgery was performed in 90.5% of the cases, whereas robotic surgery with fluorescent ureteral catheters was used in selected patients. No intraoperative ureteral injury was observed in the stent group. Catheter-related complications, including hematuria (14.3%) and urinary tract infections (9.5%), were minor and resolved before discharge. Conclusions: PUC may be beneficial in patients with a history of pelvic surgery or local recurrence of rectal cancer, in whom the risk of ureteral injury is inherently higher. Full article

The management of penetrating rectal trauma has evolved from a historic 4-D algorithm (Divert, Drain, Direct repair, and Distal washout) to a more selective approach. This case report describes a patient with multiple wounds, including a high-grade extraperitoneal rectal injury resulting from a pelvic explosive injury. The patient was successfully treated with intraluminal vacuum therapy (ILVT). This case highlights ILVT as a novel method for managing complicated blast-related rectal injuries. While there are limited publications on combat-related penetrating rectal injuries that provide evidence-based guidelines, we suggest an aggressive surgical approach combined with negative pressure wound therapy for optimal patient outcomes.

Background: Percutaneous screw fixation has increasingly been used for pelvic ring fracture fixation. In older adult patients, especially in patients with a fragility fracture of the pelvis (FFP), minimally invasive techniques followed by early ambulation have been promoted in order to regain pre-injury levels of mobility and independence. The purpose of this study was to evaluate patient-centered outcomes, including post-operative pain relief, functional performance, and satisfaction, in older adults with pelvic ring fractures treated with percutaneous screw fixation and to assess injury characteristics, complications, and return-to-home rates. Methods: In this retrospective cohort study, patients 50 years and older who had their pelvic fracture treated in the Amsterdam UMC location AMC between January 2019 and December 2022 were identified. After a minimum follow-up period of 6 months, a questionnaire was conducted by phone to evaluate the pain, current living situation, and mobility of the patients. Results: A total of 51 patients were included in this study with a median age of 74 years (IQR 62–82), and the vast majority were female (n = 40, 78%). Over half of the pelvic fractures were caused by low-energy trauma (n = 29, 57%). Unilateral or bilateral sacral fractures with unilateral anterior ring fractures were the most common fracture pattern. The interoperative complication rate was 4%, and the in-hospital complication rate was 23%. Forty-five patients were reached to complete the questionnaire. Forty patients (91%) returned to an acceptable level of mobility after treatment, and almost all (n = 44, 98%) were pleased with the results of the surgery. Conclusions: Percutaneous screw fixation of pelvic fractures in older adult patients is a safe and effective operating technique. Most patients preserve their pre-morbid functionality and are able to return to their previous place of residence after admission. Furthermore, patients are almost unanimously very pleased with the results of the surgery despite some residual pain complaints. Full article

Background: Mid-shaft clavicle fracture fixation carries neurovascular injury risk. The purpose of this study was to compare bicortical compression and unicortical locked clavicle plate constructs biomechanically. Materials and Methods: Ten fourth-generation composite transverse mid-shaft clavicle osteotomy specimens were assigned to two groups, and each clavicle was fixed with an eight-hole second-generation 3.5 mm pelvic reconstruction plate placed superiorly. Group one included five fixed with bicortical compression screws and group two included five fixed with unicortical locking screws. All were tested on a four-axis servohydraulic testing frame in three modes: axial rotation, anterior/posterior bending, and cephalad/caudad bending. Results: Mean construct stiffness for AP bending was 1.255 ± 0.058 Nm/deg (group 1) and 1.442 ± 0.065 Nm/deg (group 2) (p = 0.001). Mean construct stiffness for axial rotation was 0.701 ± 0.08 Nm/deg (1) and 0.726 ± 0.03 Nm/deg (2) (p = 0.581). Mean construct stiffness for cephalad bending was 0.889 ± 0.064 Nm/deg (1) and 0.880 ± 0.044 Nm/deg (2) (p = 0.807). Mean construct stiffness for caudal bending was 2.523 ± 0.29 Nm/deg (1) and 2.774 ± 0.25 Nm/deg (2) (p = 0.182). Conclusions: With transverse mid-shaft clavicle fractures, unicortical locking fixation provided comparable rigidity to bicortical compression fixation in axial rotation, cephalad bending, and caudal bending; it provided greater rigidity in AP bending.

Background/Objectives: Posterior pelvic ring fractures are severe injuries requiring surgical stabilization, often through sacroiliac (SI) screw fixation. However, improper screw placement poses risks of neurovascular injury and implant failure. Defining a precise safe zone for screw placement is crucial to improving surgical accuracy and reducing complications. Methods: A computational study was conducted using a CT scan of a 75-year-old male patient to establish a safe zone for SI screw placement. Manual segmentation and 3D modeling techniques were used to analyze bone density distribution. A 2D lateral projection of the sacrum was generated to identify high-density regions optimal for screw placement. While the general principle of targeting areas of higher bone density for screw insertion is well established, this study introduces a novel computational method to define and visualize such a safe zone. The resulting region, termed the Ramadanov–Zabler Safe Zone, was delineated based on this analysis to ensure maximal intraosseous fixation with minimal risk of cortical breaches. Results: A high-resolution 3D model of the sacral region was successfully generated. Standard thresholding methods for segmentation proved ineffective due to low bone density, necessitating a freehand approach. The derived 2D projection revealed regions of higher bone density, which were defined as the Ramadanov-Zabler Safe Zone for screw insertion. This zone correlates with areas providing the best structural integrity, thereby reducing risks associated with screw misplacement. Additionally, intraoperative and postoperative imaging from a representative case is included to illustrate the translational feasibility of the proposed technique. Conclusions: The Ramadanov–Zabler Safe Zone offers a reproducible, CT-based computational approach to guide for SI screw placement, enhancing surgical precision and patient safety. This CT-based computational approach provides a standardized reference for preoperative planning, minimizing neurovascular complications and improving surgical outcomes. This pilot technique is supported by preliminary clinical imaging that demonstrates feasibility for intraoperative application. Further validation across diverse patient populations is recommended to confirm its clinical applicability. Full article
