Can Nondisplacement Osteoporotic Pubic Rami Fracture Be Life-Threatening Injuries? A Case Report, Overview, and Algorithm Protocol for Management.

Pubic rami fractures in the geriatric population are usually osteoporotic fractures resulting from low energy trauma and are characterized as stable injuries. Established treatment of these injuries is conservative, including rest, analgesic medication, and progressive active mobilization. These injuries are life-threatened when pubic rami fractures are accompanied by acute bleeding, either from an injury to a vessel (corona mortis) or from medication (anticoagulant or antiplatelet) for comorbidities, then. In this case study, we present the unusual case of an 82-year-old woman admitted to the emergency department 24 hours after a simple fall, causing nondisplacement osteoporotic pubic rami fracture, who, after 48 hours, developed a hematoma on the contralateral side of the pelvis, with progressive anemia and acute abdominal pain. This study has 2 objectives: to increase awareness of this life-threatening injury in the emergency department and to describe diagnosis and treatment modalities.

van Neck-Odelberg disease: a common but poorly known and often misdiagnosed condition.

van Neck-Odelberg disease, a condition involving the ischiopubic synchondrosis in children, is a commonly encountered but poorly known ailment, which is now considered a normal variant. Symptoms can include pain, discomfort, and fever, leading to van Neck-Odelberg disease often being discovered in the context of patients presenting with non-specific clinical manifestations. In this essay, we describe what is currently known about van Neck-Odelberg disease and illustrate the condition using images acquired from multiple patients, with some using multiple imaging techniques from the same patients. Awareness of van Neck-Odelberg disease is essential for radiologists who are involved in the treatment of children, as well as for paediatricians, to prevent misdiagnosis and unnecessary invasive procedures for what is a benign and self-resolving condition.

Ileal conduit obstruction secondary to tethering of the small bowel anastomosis to the pubic bone.

We present the case of a late 60s male who presented to hospital 3 years postradical cystectomy and ileal conduit diversion with polyuria and acute kidney injury. CT of the kidneys, ureters and bladder (KUB) revealed mild hydronephrosis of a solitary left kidney and a 3-cm calculus in the ileal conduit. The patient subsequently underwent a laparotomy which revealed the cause of obstruction to be tethering of the small bowel anastomosis to the pubic bone. The conduit was excised with the calculus in situ and a new conduit was fashioned. The patient recovered from surgery without complication, and his kidney function improved.

Significant relationship between musculoaponeurotic attachment of the abdominal and thigh adductor muscles to the pubis: implications for the diagnosis of groin pain.

Groin pain is prevalent in orthopedic and sports medicine, causing reduced mobility and limiting sports activity. To effectively manage groin pain, understanding the detailed anatomy of supporting muscles is crucial. This study aimed to investigate the musculoaponeurotic attachments on the pubis and the relationship among intramuscular aponeuroses of abdominal and thigh adductor musculatures. Macroscopic analyses were performed in 10 pelvic halves. The bone morphology of the pubis was assessed in two pelvic halves using microcomputed tomography. Histological investigations were conducted in two pelvic halves. The external oblique aponeurosis extended to the adductor longus aponeurosis, forming conjoined aponeurosis, which attached to a small impression distal to the pubic crest. The gracilis aponeurosis merges with the adductor brevis aponeurosis and is attached to the proximal part of the inferior pubic ramus. The rectus abdominis and pyramidalis aponeuroses were attached to the pubic crest and intermingled with the gracilis-adductor brevis aponeurosis, forming bilateral conjoined aponeurosis, which attached to a broad area covering the anteroinferior surface of the pubis. Histologically, these two areas of conjoined aponeuroses were attached to the pubis via the fibrocartilage enthesis. Microcomputed tomography revealed two distinctive bone morphologies, a small impression and an elongated osseous prominence on pubis, corresponded to the two areas of conjoined aponeuroses. This study demonstrated close relationships between the aponeurotic attachment of the external oblique and adductor longus, and between the rectus abdominis, pyramidalis, gracilis, and adductor brevis. The findings of aponeurotic complexes would aid in diagnostic and surgical approaches for athletic groin pain.

Comparison of two surgical interventions for advanced stages pubis and pubic symphysis tuberculosis in adults: A retrospective study of 33 cases.

PURPOSE: To compare the clinical efficacy of two surgical interventions in treating advanced stages TB of the pubis and pubic symphysis. METHODS: Between June 2010 and January 2020, 33 cases of the advanced pubis and pubic symphysis TB were treated with a one-stage debridement procedure (debridement only group, n = 15) or a one-stage debridement with bone grafting and plate fixation procedure (debridement + plating group, n = 18). The visual analog scale (VAS) score, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), operation time, intraoperative blood loss, complications, time of bone graft fusion, and improvement in the mental component summary (MCS) and physical component summary (PCS) of Short Form-36 (SF-36) were compared and analyzed. RESULTS: All patients were followed for 24.9 (SD 1.6) months. All patients were completely cured of the pubis and pubic symphysis TB with no recurrence. There were no significant differences (P >0.05) between the two groups in terms of age, follow-up period and intraoperative blood loss. The post-operative VAS scores, ESR and CRP levels, PCS and MCS scores of two groups significantly improved compared to pre-therapy. The mean operation time in debridement + plating group was 140.9 (43.2) min, which was significantly longer than in debridement only group [94.9(21.8) min, P < 0.01]. The final follow-up (FFU) indices of the VAS score in debridement only group were higher than those in debridement + plating group [1.9 (0.8) vs 1.3 (0.5), P=0.012]. A satisfactory average bony fusion time of 12.2 (3.3) months was achieved in debridement + plating group . CONCLUSIONS: A one-stage debridement, bone grafting, and reconstruction plate fixation procedure achieved reconstruction of the integrity and stability of the pelvic ring, pain relief, and rapid cure of bone TB. This procedure is a safe and effective treatment option for advanced pubis and pubic symphysis TB.

Osteitis pubis following holmium laser enucleation of the prostate.

Osteitis pubis is a rare, inflammatory condition involving the pubic symphysis. While osteitis pubis has been reported following many urological procedures, including those addressing bladder outlet obstruction such as transurethral resection of the prostate, it has never been reported after holmium laser enucleation of the prostate (HoLEP). Here, we detail the clinical course of a patient found to have osteitis pubis following HoLEP. This patient presented several weeks after surgery with non-specific, persistent symptoms of groin pain and difficulty ambulating, alerting our clinicians to consider osteitis pubis which was confirmed on MRI of the pelvis. While the majority of osteitis pubis cases are managed with locally invasive techniques, our patient's symptoms were successfully managed conservatively with Foley catheter placement, oral antibiotics and close follow-up. At 9 months postoperative, the patient has reported complete resolution of symptoms and continues to be followed closely.

Comparison of the two surgery methods combined with accelerated rehabilitation in the treatment of lateral compression type 1 pelvic fractures in the elderly.

BACKGROUND: Treating lateral compression type 1 (LC1) pelvic ring injuries in older patients is controversial. This study evaluated surgical treatments combined with ERAS for treating LC1 pelvic fractures in the elderly. METHODS: In this retrospective study, patients who underwent surgery with INFIX (supra-acetabular spinal pedicle screws, and a subcutaneous connecting rod; the experimental group) or superior pubic ramus cannulated screw (the control group) fixation of LC1 pelvic fracture from January 2019 to January 2022 were reviewed. Injury radiography and computed tomography were performed to determine the Young-Burgess classification. All patients performed standardized early rehabilitation exercises after surgery and were followed up for > 12 months. After surgery, the Matta score and the visual analog scale (VAS) were evaluated, and the postoperative weight-bearing time and the length of stay (LOS) were recorded. The Barthel index and the Majeed score were evaluated at 4 months after surgery and at the last follow-up. RESULTS: Fifty-three patients were included. Thirty-two patients included in the experimental group had a mean age of 75.0 ± 6.2 (range, 66-86) years, and the other 21 patients in the control group had a mean age of 74.6 ± 4.6 (range, 68-83) years. The mean follow-up time was 13.1 ± 1.6 (range, 12-18) months in the experimental group and 13.4 ± 1.3 (range, 12-16) months in the control group. There were no significant differences in follow-up time between the groups (P > 0.05). The mean VAS score, time to weight-bearing, and LOS were 2.0 ± 0.7 (range, 1-3), 1.1 ± 0.3 (range, 1-2) d, and 5.8 ± 0.9 (range, 4-7) d in the experimental group and 2.3 ± 1.2 (range, 1-5), 2.5 ± 1.6 (range, 1-7) d, and 6.1 ± 1.6 (range, 5-11) d in the control group, respectively. Between the two groups, there was a significant difference in the postoperative time to weight-bearing (P < 0.05), while there was no significant difference in the LOS (P > 0.05). No bedrest-related complications occurred in either group. The Matta score was 90.6% in the experimental group and 90.4% in the control group (P > 0.05). At the 4-months follow-up, the experimental group had a better Barthel index and Majeed score compared with the control group, which were 86.1 ± 6.2 (range, 70-95) vs. 81.2 ± 4.1 (range, 75-90) and 86.3 ± 3.3 (range, 78-91) vs. 80.3 ± 3.9 (range, 76-86), respectively. The experimental group had better early rehabilitation effect than the control group. There was no significant difference in Barthel index and Majeed score between the two groups at the last follow-up (P > 0.05). CONCLUSION: Both INFIX and intramedullary superior pubic ramus cannulated screws can successfully treat LC1 pelvic fractures and reduce bed rest complications among older patients.

Measuring pelvises in 3D surface scans and in MDCT generated virtual environment: Considerations for applications in the forensic context.

Virtual Anthropology (VA) transposes the traditional methods of physical anthropology to virtual environments using imaging techniques and exploits imaging technologies to devise new methodological protocols. In this research, we investigate whether the measurements used in the Diagnose Sexuelle Probabiliste (DSP) and Ischio-Pubic Index (IPI) differ significantly when 3D models of a bone are generated using 3D surface scans (3DSS) and Multidetector Computed Tomography (MDCT) scans. Thirty pelvises were selected from the SIMON identified skeletal collection. An equal ratio of females to males was sought, as well as a good preservation of the bones. The pelvises were scanned using an MDCT scanner and a 3D surface scanner. The measurements of the DSP and IPI methods on the dry bones (referred to as macroscopic measurements here), and then to the 3D models. The intra- and interobserver, using the Technical Error of Measurement (TEM) and relative Technical Error of Measurement (rTEM) error was assessed, and we aimed to observe if the measurements made on the MDCT and 3DSS generated models were significantly different from those taken on the dry bones. Additionally, the normality of the data was tested (Shapiro-Wilk test) and the differences in measurements was evaluated using parametric (Student t-tests) and non-parametric (Wilcoxon) tests. The TEM and rTEM calculations show high intra and interobserver consistency in general. However, some measurements present insufficient inter- and intraobserver agreement. Student t and Wilcoxon tests indicate potentially significant differences of some measurements between the different environments. The results show that especially in the virtual environment, it is not easy to find the right angle for some of the DSP measurements, However, when comparing the measurement differences between dry and virtual bones, the results show that most of the differences are less than or equal to 2.5 mm. Considering the IPI, the landmarks are already difficult to determine on the dry bone, but they are even more difficult to locate in the virtual environment. Nevertheless, this study shows that quantitative methods may be better suited for application in the virtual environment, but further research using different methods is needed.

Delayed diagnosis of parathyroid cancer manifested with pubic bone lesions and chronic kidney failure. Tricks and pitfalls of management.

INTRODUCTION: Parathyroid cancer (PTC) is an extremely rare malignancy with an incidence of 5.7 per 10 million people. The exact preoperative or intraoperative diagnosis is difficult, but of paramount importance, because resection with negative margins is the only effective treatment. CASE REPORT: A 46-years-old female was referred from another hospital with a diagnosis of "hyper-functioning thyroid nodule", based on the ultrasound showing a lesion of the right thyroid lobe and elevated FT4. At the admission, she had severe pain in the right inguinal area, fatigue, muscle weakness, and excessive diuresis. The blood assay demonstrated serum calcium of 4.02 mmol/l, parathyroid hormone of 1433.2 pg/ml, FT4 of 17.49 pmol/l, creatinine of 296 µmol/l. CT showed a tumor of the right thyroid lobe with a size of 2.5. A right lobectomy was performed. Right parathyroid glands were not found. Because of the constellation for hyperparathyroidism and suspicion of parathyroid malignancy ipsilateral and central lymph node dissection and partial removal of the right sternothyroid muscle were performed, which correlated with a significant intraoperative drop in the parathyroid hormone. Three months later, a re-resection was performed because of SPECT-CT evidence for residual parathyroid tissue. CONCLUSION: The timely diagnosis of PTC is a prerequisite for a good outcome. The best preoperative indicators are serum parathyroid hormone > 4 times above the upper limit, serum calcium > 14 mg/dL, a palpable neck mass, and a local invasion found intraoperatively. The only curative treatment is the complete removal of the tumor with a negative margin. KEY WORDS: Delayed diagnosis, Hyperparathyroidism, Parathyroid cancer, Surgery.

Symphyseal plating for pelvic fracture in a morbidly obese patient: operative challenges and innovation of a novel 'wire-ramp plate-sliding method'.

We are describing a case report of a morbidly obese patient (body mass index 41) in his mid-40s with Young and Burgess Anteroposterior Compression type II injury (AO Foundation/Orthopaedic Trauma Association type B1.2) managed by symphyseal plating. Morbid obesity made working at a depth very difficult; hence, we adopted a novel 'wire-ramp plate-sliding method'. In this method, two strong sturdy K-wires inserted through the medial-most plate holes into the pubis acted as a ramp over which the plate was pushed/slid distally. During this manoeuvre, the K-wires passing through the plate holes were used as a reduction tool. The patient also had a wedge fracture of the distal femoral shaft which was managed by retrograde femoral nailing. At 1-year follow-up, the pelvic continuity is maintained and the fracture has united. The patient is able to do full weight-bearing and is back to his normal life.

Isolated lesions of the pubis.

The osseous pelvis is a well-known area of various primary and secondary bone tumours, tumour mimics, and infections. Isolated lesions of the pubis (ILP) are rare, with few case reports in the literature. Given their sparsity, such lesions may pose a great diagnostic challenge due to varied clinical presentations and imaging features. In this study, we report the largest case series of ILP. We discuss the patient demographics, differentials, surgical approaches, and management.

Cadaveric Analysis of Key Anatomic Structures of Athletic Pubalgia.

PURPOSE: This study proposes to establish in-depth inspection of the anatomic structures involved with the pathology of athletic pubalgia in a cadaver model. METHODS: Eight male fresh frozen cadavers were dissected in a layered fashion. The rectus abdominis (RA) and adductor longus (AL) tendon insertions were isolated to quantify the size of the anatomic footprint and distance from the surrounding anatomy. RESULTS: The RA insertional footprint was 1.65 cm (SD, 0.18) in width by 1.02 cm (SD, 0.26) in length, and the AL insertional footprint on the underside of the pubis was 1.95 cm (SD, 0.28) in length by 1.23 cm (SD, 0.33) in width. The ilioinguinal nerve was 2.49 cm (SD, 0.36) lateral to the center of the RA footprint and 2.01 cm (SD, 0.37) lateral to the center of the AL footprint. The spermatic cord and the genitofemoral nerve were just lateral to the ilioinguinal nerve and were 2.76 cm (SD, 0.44) and 2.66 cm (SD, 0.46) from the rectus and AL footprints, respectively. CONCLUSION: Surgeons should be cognizant of these anatomic relations during both initial dissection and tendon repair to optimize repair and avoid iatrogenic injury to critical structures in the anterior pelvis.

Disseminated Nocardia farcinica infection associated with bacteraemia and osteomyelitis pubis in an elderly patient.

OBJECTIVE: We describe a rare case of a disseminated Nocardia farcinica infection associated with hip osteomyelitis. METHODS: A 91-year-old female patient was admitted with oedema of her right leg, fever of 38 °C and data consistent with ruptured Baker's cyst. A disseminated Nocardia farcinica infection including bloodstream infection, pneumonia and multiple abscesses along both lower limbs was observed. RESULTS: After a four-week course of 320 mg/1600 mg/12 h of intravenous trimethoprim/sulfamethoxazole and multiple chirurgic drainages the patient was discharged with oral trimethoprim/sulfamethoxazole. Nevertheless, the patient expired done month after being discharged from the hospital. CONCLUSIONS: The implementation of a combination of intravenous antibiotics and drainages resulted in an initial improvement in the patient's condition. However, despite these interventions, the patient ultimately passed away probably due to natural causes.

Emphysematous Osteomyelitis of the Pubis Associated With Necrotizing Soft Tissue Infection of the Thigh.

Emphysematous osteomyelitis (EO) is a rare condition identified through the presence of intraosseous gas. It is frequently fatal even with prompt recognition and management. We report a case of EO presenting with a necrotizing soft tissue infection of the thigh in the setting of prior pelvic radiation. The purpose of this study was to highlight the unusual association between EO and necrotizing soft tissue infection.
