Hip joint rice body bursitis combined with hip dysplasia and pelvic fracture: a case report.

BACKGROUND: Rice body formation is an uncommon, nonspecific inflammatory process. Certain clinical features, such as chronic synovitis associated with rheumatoid arthritis, tuberculous arthritis, and osteoarthritis, can induce a non-specific response that may lead to the development of rice bodies. Currently, the etiological and prognostic significance of rice bodies remains unknown. Magnetic resonance imaging (MRI) is the preferred diagnostic imaging modality for evaluating rice body formation. CASE PRESENTATION: The patient, a 44-year-old female, presented with bursitis of the hip joint and the presence of numerous rice bodies. This case is exceptionally rare and unusual as it involves a combination of hip dysplasia and pelvic fracture. The patient underwent a one-stage resection of the rice body, internal fixation of the acetabular fracture, and two-stage total hip arthroplasty, resulting in an immediate improvement in her symptoms. We reviewed the relevant literature and observed that the majority of rice bodies were predominantly found within the capsules of the shoulder and knee joints, while instances of hip joint rice body bursitis were relatively infrequent. To our knowledge, there have been no previous reports documenting a case of hip joint rice body bursitis in conjunction with hip dysplasia and pelvic fracture. CONCLUSION: This paper presents the rare case of hip joint rice body bursitis combined with hip dysplasia and pelvic fracture, and is one of the highlights.

Bladder inflation to reduce hemorrhage secondary to a pelvic fracture.

Bladder inflation may be a temporizing measure to tamponade pelvic bleeding in select trauma cases to bridge the patient to definitive interventions. Ultrasonographic confirmation of an intact bladder with an adjacent pelvic haematoma in a shocked adult with pelvic fracture is used for subject selection. An illustrative example of physiologic and interventional radiological control of pelvic bleeding following bladder inflation with sterile saline is presented.

A clinical assessment of preperitoneal packing adequacy for pelvic fracture bleeding control.

Background: This study aimed to objectively assess the laparotomy pads to potential hemorrhage sites proximity in pelvic fracture patients who underwent post-pre peritoneal packing (PPP) CT scans with packs in situ. Methods: The CT scans of 19 patients were assessed to measure the distance between laparotomy pads and predetermined pelvic anatomical landmarks. Results: A total of 38 measurements showed that the median pack-to-point distance for the sacroiliac joint was 2.7 cm (IQR, 2.1-4.0), for the common iliac artery 4.1 cm (IQR, 3.2-5.0), for the external iliac artery 0 cm (IQR, 0.0-0.2), for the internal iliac artery 0.1 cm (IQR, 0-0.7), and for the iliac bifurcation 2.0 cm (IQR, 1.7-3.9). There were 60 % direct contact measurements for the iliac arteries. Conclusion: This study shows that with adequately executed PPP a reasonable proximity of laparotomy packs to the potential bleeding sites to provide tamponade for arresting hemorrhage may be achieved.

Use of a newly developed minimally invasive bilateral fixed angle locking system in the treatment of pathological pelvic fractures: a case series.

BACKGROUND: Metastatic bone disease (MBD) and its complications have a significant impact on patients' quality of life. Pathological fractures are a particular problem as they affect patient mobility and pose a high risk of non-union. The pelvis is frequently affected by MBD and its fixation is challenging. We present a case series of three pathological sacral fractures treated with a new minimally invasive bilateral fixed angle locking system. CASE PRESENTATION: Case 1 and 2 suffered a pathological transforaminal sacral fracture without adequate trauma in stage 4 carcinomas (gastric cancer and breast cancer). Both were initially treated with non-surgical treatment, which had only a limited effect and led to imminent immobility. Both were operated on with fluoroscopic navigation and underwent transsacral SACRONAIL® stabilisation according to CT morphology (S1 + S2 and S1 respectively). Immediately after the operation, pain decreased and mobilisation improved. Case 3 had a pathological transalar sacral fracture during the 2nd cycle of chemotherapy due to non-Hodgkin's lymphoma. He soon became immobile and could only move in a wheelchair. The operation was performed with CT navigation due to the very small corridors and an implant was inserted in S1 and S2. The patient reported immediate pain relief and his ability to walk improved over the following months. Despite continued chemotherapy, no wound complications occurred. CONCLUSIONS: The cases show the advantages of the minimally invasive bilateral fixed angle locking system SACRONAIL® in the treatment of patients with pathological sacral fractures. It allows immediate full weight bearing and the risk of secondary surgical complications is low. All cases showed an improvement in pain scores and mobility.

Orthogeriatric co-management in pelvic and acetabular fractures.

BACKGROUND: Osteoporosis, age and frailty significantly impacts outcomes in fragility fractures of the pelvis, increasing morbidity and mortality. Identifying frailty aids in risk stratification and personalized care plans, enhancing recovery and reducing complications in older adults. Orthogeriatric co-management, an interdisciplinary approach combining orthopedics and geriatrics, optimizes care for older adults with fragility fractures. This model improves outcomes through integrated preoperative and postoperative care. This study examines the current literature for orthogeriatric co-management in pelvic ring or acetabular fractures, aiming to improve outcomes for older adults. CONCLUSION: Orthogeriatric co-management can be an effective tool to significantly enhances clinical care and reduces complications in older adults with pelvic ring and acetabular fractures. Studies demonstrate increased detection of urological complications and earlier patient mobilisation, alongside a notable decrease in revision surgery rates. The implementation of a specialized framework underscores the necessity for standardised orthogeriatric protocols, optimizing patient outcomes and satisfaction. Integrating geriatric expertise in surgical treatment addresses comorbidities more effectively and minimizes postoperative complications. The certification of such centers ensures adherence to quality standards, fostering continuous improvement in care. Standardised orthogeriatric management should extend to all older fracture patients.

Duverney's Fracture Fixed by Skiver Screw in a Skeletally Immature Patient: A Case Report.

Duverney's fracture, an eponym for isolated iliac wing fracture, is rather an uncommon fracture in the subset of pelvic ring fracture in the AO/OTA (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association) classification. Here, we discuss a more unique case with Duverney's fracture since the patient is a 15-year-old school-going girl with unfused physis of the ilium. After other injuries were ruled out, she underwent open reduction and fixation with a screw by the Skiver method augmented with the plate. Postoperatively, she was mobilized, and follow-up at eight months showed radiologically complete union with good functional outcome.

Retrograde Ejaculation Due to Posterior Urethral Stricture: A Rare Case Report.

Pelvic fracture is a serious injury, which has a profound impact on sexual function due to concurrent nervous and urethral injuries. In this case report, we describe a 29-year-old single man who had retrograde ejaculation as a result of a pelvic fracture-related posterior urethral stricture. The patient wanted to improve his ejaculatory ability after experiencing urethral stricture for 8 years and retrograde ejaculation for 3 years following the pelvic fracture. We precisely located and measured the patient's urethral stricture using a retrograde urethrogram, and we used transrectal color Doppler ultrasound to track the patient's ejaculation process in real time. Next, we used urethral balloon dilatation to relieve the urethral stricture. Urinary obstruction symptoms have completely resolved, and the patient was able to urinate without any obstructions. Meanwhile, the real-time transrectal color Doppler ultrasound result showed that some semen might ejaculate externally by passing through the initial stricture area, while some semen continued to flow retrogradely into the bladder.

A new approach for percutaneous ilio-sacral screw fixation: CT-based pre-operative planning with conventional fluoroscopy to reduce malposition rate and operating time.

PURPOSE: Percutaneous ilio-sacral screw (ISS) insertion using conventional C-arm fluoroscopy has been a widely employed technique for pelvic posterior ring fixation, particularly in developing regions. However, this approach presents technical challenges, leading to a high malposition rate. We introduced a new method for ISS insertion without additional equipment or software and suggested whether it could reduce the malposition rate and operating time. METHODS: This is a retrospective cohort study. The study included all patients who underwent percutaneous ISS fixation between January 2020 and December 2022. Patients treated with open reduction or other types of implants were excluded. The patients were divided into 2 groups based on the screw insertion method: Group A utilized the traditional dual-plane adjustment method, while Group B received the newly introduced method. In all cases, conventional C-arm fluoroscopy was the sole guidance during the surgical procedure. Malposition rate, radiation exposure, and operating time were compared between groups. Post-operative CT scans were used to assess screw accuracy using the Smith grading method. The Student's t-test or the Mann-Whitney U test was chosen for comparing the quantitative variables based on the normality test results. The Chi-squared test was utilized for comparing qualitative variables. RESULTS: A total of 72 patients with pelvic posterior ring disruption treated with percutaneous ISS under conventional fluoroscopy guidance were included in this study. Among them, 32 patients were in Group A and 40 patients were in Group B. In Group B, the average operation duration per screw was 33 min with 29 fluoroscopy applications, which was significantly lower than that in Group A (44 min, p < 0.001, 38 times, p < 0.001, respectively). Furthermore, the post-operative CT scan revealed that only 10.7% (6/56) of screws in Group B were inappropriately positioned according to the Smith criteria. CONCLUSION: The novel method introduced in this study demonstrated a reduction in both malposition rates and operating time compared to the traditional dual-plane adjustment method. Precise pre-operative CT planning in conjunction with conventional fluoroscopy could establish this method as a widely applicable technique for percutaneous ISS fixation.

Pelvic ring fracture in the older adults after minor pelvic trauma - is it an innocent injury?

OBJECTIVE: This study aimed to evaluate the prevalence of severe hemorrhage as a potentially life-threatening complication in elderly patients with isolated, low-energy pelvic ring fractures, which may be more common than previously described. PATIENTS AND METHODS: A retrospective cohort study was conducted at an academic level 1 trauma center, including 579 patients aged over 65 who suffered from isolated low-energy pelvic fractures between 2006 and 2020. Pelvic computer tomography (CT) scans, with or without contrast, were performed and reviewed for patients with suspected posterior ring injury or bleeding. Patients without CT scans were excluded from the study. RESULTS: Among the 123 patients with isolated pubic rami fractures, 30 (24.4 %) had bleeding with a significant hemoglobin drop (>2 g%). 21(70 %) patients of these had posterior pelvic ring involvement as compared to 45 who did not bleed (51 %, p = 0.07). There was a significantly larger proportion of patient who received anticoagulant therapy (ACT) with posterior ring injury among the bleeding group (20 % vs 3.2 % p < 0.01). Treatment included blood transfusion (19/123, 15.5 %), and arterial angiographic embolization (5/123, 4 %). No complications related to angio-embolization were observed, and all patients survived the initial 90-day period. No other source of bleeding was identified in any of these patients. CONCLUSION: Severe pelvic hemorrhage in the older adults due to a minor pelvic injury after a low-energy trauma is not an uncommon complication, especially with combination of ACT and posterior pelvic ring fracture. This indicates that these injuries more challenging than previously believed. Geriatric pelvic ring injuries should be monitored carefully with serial blood counts, and low threshold for imaging including contrast enhanced CT scans and angiography.

[Pulsed thulium laser combined with pulsed thulium laser injection for the treatment of failed urethral anastomosis].

OBJECTIVE: To investigate the clinical effect of pulsed thulium laser (PTL) combined with triamcinolone acetonide injection in the treatment of failed posterior urethral anastomosis (FPUA). METHODS: This retrospective study included 35 male patients treated in Gongli Hospital for failed posterior urethral anastomosis from January 2018 to December 2023. All the patients underwent direct-vision internal urethrotomy (DVIU) with transurethral PTL (the PTL group, n = 15) or transurethral plasma (the TUP group, n = 20), and all received intralesional injection of triamcinolone acetonide. We followed up the patients for a median of 21 months, recorded the age, length of urethral stricture, operation time, pre- and post-operative maximum urinary flow rate (Qmax), postoperative complications and recurrence of urethral stricture, and compared the data obtained between the two groups. RESULTS: All the patients smoothly completed the treatment procedures. No statistically significant differences were observed in the age, length of urethral stricture, operation time and postoperative complications between the two groups (P > 0.05). The median follow-up time for the thulium laser group and plasma group was 21.0 months (IQR 16.0－24.0) and 21.0 months (IQR 17.0－25.0), respectively, with a statistically significant difference observed in the maximum urine flow rate before and after surgery at the 12-month mark (P < 0.01). No significant disparity was found in terms of relapse-free survival between the two groups (P = 0.398) Conclusion: Pulsed thulium laser combined with triamcinolone acetonide injection can effectively maintain a short-term cicatricial stability of the urethral stricture and satisfactory urethral patency, obviously superior to plasmotomy as a remedial treatment of urethral stricture after failed posterior urethral anastomosis.

Clinical frailty and short-term outcomes after low-energy pelvic fracture in the geriatric population: Nationwide inpatient sample 2016-2018 analysis.

BACKGROUND: Pelvic fractures can be life-threatening for elderly individuals with diminished bone strength. Frailty is associated with fracture outcomes, but its impact on pelvic fracture recovery remains unexplored. The aim of this study was to investigate the association between frailty and short-term outcomes in older adults hospitalized for low-energy pelvic fractures. METHODS: Data from the Nationwide Inpatient Sample (NIS) covering the years 2005 to 2018 were reviewed. Inclusion criteria were age ≥ 60 years admitted for a low-energy pelvic fracture. Patients were categorized into frail and non-frail groups using the 11-factor modified Frailty Index (mFI-11). Association between frailty and in-hospital outcomes were determined by univariate and multivariable regression analyses. RESULTS: A total of 24,688 patients with pelvic fractures were included. The mean patient age was 80.6 ± 0.1 years, and 35 % were classified as frail. After adjustments, frailty was significantly associated with unfavorable discharge (adjusted odds ratio [aOR] = 1.07, 95 % confidence interval [CI]: 1.00-1.15, p = 0.038), prolonged hospitalization (aOR = 1.51, 95 % CI: 1.41-1.62, p < 0.001), complications (aOR = 1.42, 95 % CI:1.34-1.50, p < 0.001), and acute kidney injury (aOR = 1.68, 95 % CI: 1.56-1.82, p < 0.001). Stratified analyses based on age and fracture type showed frailty was consistently associated with adverse outcomes. CONCLUSIONS: Persons ≥60 years old with mFI-11 assessed frailty and a low-energy pelvic fracture are at higher risk of adverse in-hospital outcomes than non-frail patients. Additional research is needed to disclose the prognostic impact of clinical frailty on long-term functional outcomes and quality of life after discharge.

Clinical and radiographic predictors for angiography in pelvic trauma: An analysis of 1703 patients.

INTRODUCTION: Patients who present with hemorrhage from pelvic fractures have an increased risk of mortality with prolonged time to intervention. Identifying risk factors associated with hemorrhage can expedite treatment. In this study we explore clinical and radiographic predictors for angiography in trauma patients with pelvic fractures. METHOD: Retrospective, single-center review between 2009 and 2019 at a level 1 trauma center of all trauma patients with pelvic fractures. We excluded patients who died prior to arrival or in the trauma bay who did not undergo computed tomography ("CT"). Finalized attending descriptions of CT findings were reviewed, including size of hematomas, and presence of extravasation. Chi-square, Mann-Whitney U and multi-variate regressions were performed. RESULTS: We analyzed 1,703 trauma patients with pelvic fractures. Most common mechanisms of injury included MVC (45 %), fall (27 %) and motorcycle accident (12 %). 48 % (819/1703) of patients had pelvic hematomas on CT scan. 17 %(138/819) of patients with a hematoma also had evidence of extravasation. Significant predictors for extravasation on CT included large hematoma on CT, AIS extremity ≥2, binder placement, increased ISS, HR, and decreased GCS and SBP (p < 0.005). Significant predictors for angiography were similar, including AIS extremity ≥2, binder placement, presence of moderate and large hematoma and active extravasation on CT (p < 0.01). Stepwise logistic regression model incorporated ISS, HR, AIS extremity score, binder placement, and contrast extravasation with an AUC = 0.9345. CONCLUSION: In this large retrospective review of traumatic pelvic fractures, specific clinical and radiographic factors were significantly associated with pelvic hematomas, extravasation and/or need for angiography. Future collaborative work with orthopedics and interventional radiology is planned to better triage pelvic fracture patients and identify those at risk for bleeding that require earlier intervention.

Trends and epidemiology of lower trunk fractures in the super elderly population in the United States from 2011 to 2020.

INTRODUCTION: Fractures of the lower trunk are among the most common fractures occurring in the elderly. Super elderly individuals (i.e., those 80 years of age and older) represent a growing segment of the population and are especially prone to these fractures. The contemporary epidemiology of lower trunk fractures in the super elderly population is incompletely described in the literature. MATERIALS AND METHODS: This descriptive epidemiology study used the National Electronic Injury Surveillance System (NEISS) to examine the incidence and recent trends of lower trunk fractures (i.e., fractures of the hip, pelvis, and lumbar spine) occurring among super elderly individuals in the United States (US) from 2011 to 2020. Annual, overall, and age-/sex-specific incidence rates (IRs) were analyzed. Average annual percent change (AAPC) estimates were calculated to indicate the magnitude/direction of trends in annual injury rates. RESULTS: An estimated N=1,226,160 super elderly patients sustained lower trunk fractures over the 10-year study period for an overall IR of 100.2 per 10,000 person-years at-risk (PYR). Hip fractures accounted for the largest percentage of cases (IR=71.7 PYR), followed by lumbar spine fractures (IR=14.7), and pelvic fractures (IR=14.3). The incidence of lower trunk fractures among super elderly females (IR=121.5 PYR) was significantly greater than that of males (IR=65.7 PYR). The incidence of lower trunk fractures among nonagenarians and centenarians was significantly higher than that of octogenarians. Accounting for population growth yielded a significantly increasing annual incidence of lower trunk fractures in super elderly patients over the study period from 86.7 PYR in 2011 to 107.2 PYR in 2020 (AAPC=2.7, p<0.001). The annual incidence of both pelvic (AAPC=5.8) and lumbar spine (AAPC=6.9) fractures increased at a significantly higher rate than that of hip fractures (AAPC=1.4). CONCLUSIONS: This study suggests that the annual incidence of lower trunk fractures in the oldest cohort of patients in the US (80+ years of age) increased significantly during the recent decade from 2011 to 2020, with pelvic and lumbar fractures in particular becoming increasingly common. Increased incidence rates highlight the need for future research aimed at optimizing outcomes and quality of life in this frail and ever-growing segment of the population.

Transobturator-cable-fixation in pelvic ring injuries with symphyseal disruption - a last resort?

PURPOSE: The role of transobturator-cable-fixation (TOCF) in traumatic symphyseal rupture of the pelvic ring remains unclear. This case series aims to evaluate TOCF in complex and revision cases in pelvic surgery. METHODS: A retrospective analysis of a chronological case series was conducted, studying pelvic fractures stabilized using TOCF between January 2006 and December 2022. The variables considered included age, gender, fracture classification, Injury Severity Score (ISS), Body Mass Index (BMI), trauma mechanism, time to surgery, fixation technique, hospital duration, complications, status on discharge (Glasgow Outcome Scale; GOS), follow-up time and indication for the use of TOCF. RESULTS: All patients (N = 7) were male with a mean age of 64 years and a mean BMI of 29. The mean ISS was 45, with the lowest ISS of 25, indicating that only polytraumatized patients were included. Two anterior-posterior-compression-, four lateral-compression-, and one vertical-shear-pelvic-injury were identified. TOCF was added in six cases to support symphyseal plating and in one case to external fixation. The mean hospital stay was 49 days and the mean follow-up duration was 8.5 months. No complications associated with TOCF were observed during the surgical procedure or follow-up. CONCLUSION: TOCF showed no procedure-associated complications and effectively supported symphyseal healing in all cases. The main indications were obesity, poor bone quality in elderly patients, and revision cases. TOCF could be considered as a last treatment option in open-book pelvic injuries where plating or external fixation is at risk to fail.

Thirty-Day Surgical Morbidity and Mortality in Pelvic and Acetabular Fracture Patients Presenting to a Tertiary Care Hospital in Karachi, Pakistan.

INTRODUCTION: Pelvic fractures, encompassing a spectrum from minor to life-threatening injuries, pose challenges in trauma management. This study focuses on short-term outcomes, exploring morbidity and mortality within 30 days postoperative, among pelvic fracture patients at a tertiary care hospital in Karachi, Pakistan. The majority of pelvic injuries result from intense blunt trauma, with associated risks of concomitant injuries. Pelvic fractures are linked to early complications such as hemorrhage, thromboembolism, and infections, influencing mortality rates. METHODOLOGY: A prospective cohort study involving 53 surgically managed pelvic fracture patients was conducted at Aga Khan University Hospital, Karachi. Variables such as age, gender, comorbidities, mechanism of injury, associated injuries, and presenting vitals were documented. Thirty-day morbidity included surgical site infections, hemorrhagic shock, nerve injuries, and others. Statistical analyses assessed associations between patient characteristics and morbidity. RESULTS: The study revealed a median age of 37 years, with 77% male patients. Most fractures result from motor vehicle accidents. Morbidity occurred in 31.6% of cases, primarily associated with the presence of associated injuries. Postoperative complications included neurological deficits (15.1%) and pulmonary complications (9.4%). No 30-day mortality was reported. DISCUSSION: The study highlights the importance of a multidisciplinary approach in managing pelvic fractures, emphasizing the association between associated injuries and postoperative morbidity. Comorbidities did not significantly impact morbidity, emphasizing the traumatic nature's independent contribution. Timely presentation (median 20 hours) and efficient trauma systems are crucial for optimal outcomes. CONCLUSION: This research contributes insights into short-term outcomes following pelvic fracture fixation in a Pakistani tertiary care setting. By exploring a range of parameters, the study emphasizes the need for comprehensive management strategies to minimize complications and improve patient outcomes. Bridging critical knowledge gaps, this research informs clinical decision-making for pelvic fracture patients in this region.

The mode of delivery after operative fixation of pelvic ring fractures-a retrospective observational study.

PURPOSE: The purpose of this study is to investigate whether retained hardware after surgical treatment for a pelvic fracture prior to pregnancy affects the choice of delivery method. The study aims to provide insights into the rates of vaginal delivery and caesarean sections, understanding whether the mode of delivery was influenced by patient preference or the recommendations of obstetricians or surgeons, and examining the rate of complications during delivery and postpartum. METHODS: All women of childbearing age who underwent surgical fixation for a pelvic ring fracture between 1994 and 2021 were identified. A questionnaire was sent about their possible pregnancies and deliveries. Of the included patients, surgical data were collected and the fracture patterns were retrospectively classified. Follow-up was a minimum of 36 months. RESULTS: A total of 168 women with a pelvic fracture were identified, of whom 13 had a pregnancy after surgical stabilization. Eleven women had combined anterior and posterior fracture patterns and two had isolated sacral fractures. Four women underwent combined anterior and posterior fixation, the others either anterior or posterior fixation. Seven women had a total of 11 vaginal deliveries, and 6 women had 6 caesarean sections. The decision for vaginal delivery was often the wish of the mother (n = 4, 57%) while the decision to opt for caesarean section was made by the surgeon or obstetrician (n = 5, 83%). One woman in the vaginal delivery group suffered a postpartum complication possibly related to her retained pelvic hardware. CONCLUSION: Women with retained hardware after pelvic ring fixation can have successful vaginal deliveries. Complications during labor or postpartum are rare. The rate of primary caesarean sections is high (46%) and is probably influenced by physician bias. Future research should focus on tools that can predict labor outcomes in this specific population, and larger multicenter studies are needed. LEVEL OF EVIDENCE: Level III.

Lower abdominal cyst complicated with suspected infection following INFIX internal fixation for pelvic fracture: a report of two rare cases.

BACKGROUND: The Internal Fixator (INFIX) is a popular method, known for its minimal invasiveness and short operation time, for treating anterior pelvic ring fractures. Studies have shown that postoperative complications may occur, including anterolateral femoral cutaneous nerve injury, the femoral nerve paralysis, and delayed fracture healing. These complications are believed to be related to surgical stimulation, an excessively long lateral end of the connecting rod, a small distance between the screw and bone surface, insufficient pre-bending of the connecting rod, and difficulties in fracture reduction. CASE PRESENTATION: We report two unique cases of lower abdominal pseudocyst complicated with suspected infection after INFIX treatment of pelvic fractures at our trauma center. Following surgical removal of the internal fixation, resolution of the cysts was observed in both patients, and subsequent postoperative follow-up revealed the absence of any residual sequelae. These cases have not been reported in previous literature reviews. DISCUSSION: The lower abdominal cysts, potentially arising from the dead space created during intraoperative placement of the INFIX rod, may increase infection risk. The etiology remains uncertain, despite the presence of abnormal inflammation markers in both cases, and staphylococcus aureus found in one. These cysts were confined to the lower abdomen, not involving the internal fixation, and hence, only the INFIX was removed. Postoperative oral cefazolin treatment was successful, with resolved pseudocysts and no subsequent discomfort. CONCLUSION: We report two unprecedented cases of post-INFIX abdominal cysts, with a suspected link to intraoperative dead space. Despite uncertain etiology, successful management involved INFIX removal and oral cefixime therapy. These findings necessitate further exploration into the causes and management of such complications.

Unilateral Traumatic Testicular Dislocation in a Patient of Pelvic Diastasis and Spine Fracture in an Adult: A Case Report and Review of Literature.

Introduction: With advancement, the occurrence of road traffic accidents is common. Timely management of fractures of the spine and pelvis is of the utmost importance for survival, ambulation, and maintenance of normal life. Genitourinary complications following pelvic ring injuries are not unknown; however, testicular dislocation is rare and can cause significant morbidity if not managed appropriately. Case Report: Our case was a 25-year-old male who was presented to the tertiary trauma center following a motorcycle accident. He had an anteroposterior compression (APC) fracture of the pelvic ring (APC-III, Arbeitsgemeinschaft für Osteosynthesefragen 61-C1.2), D8-D9 vertebra compression fracture, fracture of the left distal radius, and radio-carpal dislocation. However, no concomitant genitourinary injury was noticed at the initial assessment. After resuscitation, the pelvis was planned to be fixed with an anterior symphyseal plate and posterior sacroiliac joint fixation using 2 cancellous screws. While using Stoppa's approach, surprisingly, the right testicle was observed to be inferior to the pubis. Trauma surgery help was sought and the dislocated testis was reduced and managed with orchidopexy after checking the viability. At the follow-up of 1 year,the pelvic fracture was united without urogenital complication. Conclusion: In cases of complex pelvic ring injury, a careful genital examination should be performed and a multi-disciplinary team approach with compromising of radiology, traumatology, and orthopedics departments should be adopted for better patient outcomes.

[Effectiveness of reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures].

Objective: To explore the effectiveness of reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures. Methods: Between January 2022 and February 2023, 10 patients with Tile type B pelvic fractures were admitted. There were 6 males and 4 females with an average age of 45.5 years (range, 30-71 years). The fractures were caused by traffic accident in 5 cases, bruising by heavy object in 3 cases, and falling from height in 2 cases. The interval between injury and operation ranged from 4-13 days (mean, 6.8 days). There were 2 cases of Tile type B1 fractures, 1 case of Tile type B2 fracture, and 7 cases of Tile type B3 fractures. After closed reduction under assistance of reduction robot, the anterior ring was fixed with percutaneous screws with or without internal fixator, and the posterior ring was fixed with sacroiliac joint screws under assistance of navigation robot. The time of fracture reduction assisted by the reduction robot was recorded and the quality of fracture reduction was evaluated according to the Matta scoring criteria. The operation time, intraoperative fluoroscopy frequency and time, intraoperative bleeding volume, and incidence of complications were also recorded. During follow-up, the X-ray film of pelvis was taken to review the fracture healing, and the Majeed score was used to evaluate hip joint function. Results: The time of fracture reduction was 42-62 minutes (mean, 52.3 minutes). The quality of fracture reduction according to the Matta scoring criteria was rated as excellent in 4 cases, good in 5 cases, and poor in 1 case, with excellent and good rate of 90%. The operation time was 180-235 minutes (mean, 215.5 minutes). Intraoperative fluoroscopy was performed 18-66 times (mean, 31.8 times). Intraoperative fluoroscopy time was 16-59 seconds (mean, 28.6 seconds). The intraoperative bleeding volume was 50-200 mL (range, 110.0 mL). No significant vascular or nerve injury occurred during operation. All patients were followed up 13-18 months (mean, 16 months). X-ray films showed that all fractures healed with the healing time of 11-14 weeks (mean, 12.3 weeks). One case of ectopic ossification occurred during follow-up. At last follow-up, the Majeed score was 70-92 (mean, 72.7), and the hip joint function was rated as excellent in 2 cases and good in 8 cases, with the excellent and good rate of 100%. Conclusion: The reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures has the characteristics of intelligence, high safety, convenient operation, and minimally invasive treatment, which can achieve reliable effectiveness.

Infected closed pelvic fractures in two adults - Case report.

INTRODUCTION: Infections following closed fractures in immunocompetent adults are rare but can have significant consequences if not promptly diagnosed. CASE PRESENTATION: We present two cases of immunocompetent adults admitted to a hospital in Tanzania with closed pelvic fractures who were found to have infections intraoperatively. Both patients responded well to treatment with one delaying to clear the infection. CLINICAL DISCUSSION: Because it rarely happens infected closed fractures are difficult to diagnose prior to surgery and treatment is controversial, most authors propose priority should be getting the fracture to unite then treatment of infection. CONCLUSION: This report adds to the existing literature on infections following closed fractures and highlights the importance of considering infection in closed fractures and tailoring management strategies to individual patient factors.
