[LANGUAGE= \"English\"] This case report explores the management of a traumatic hemipelvectomy—a rare and devastating injury characterized by a high mortality rate. The patient, a 12-year-old male, suffered right lower extremity amputation and right hemipelvectomy due to a deglov-ing injury from a non-vehicle-related accident at another institution. Initially, an urgent reconstruction of the right pelvic region and suprapubic tissue defects was performed using a posterior-based fasciocutaneous flap. Following this, the patient was transferred to the pediatric intensive care unit at our hospital with a suspected diagnosis of necrotizing fasciitis. Treatment included broad spectrum antibiotics and multiple debridements to avert the onset of sepsis. Eventually, reconstruction of a 60 x 25 cm defect covering the lower back, abdomen, gluteal, and pubic regions was achieved through serial split-thickness skin grafts and a pedicled anterolateral thigh flap. The patient made a remarkable recovery, regained mobility with the aid of a walker, and was discharged in good health 22 weeks after the initial accident. This case report underscores the importance of serial debridements in preventing sepsis, the use of negative pres-sure vacuum dressing changes, the initiation of broad-spectrum antibiotics based on culture results during debridements, and prompt closure of the defect to ensure survival after traumatic hemipelvectomy. Familiarization with the principles discussed here is crucial to minimizing mortality rates and optimizing outcomes for this rare injury.[LANGUAGE= \"Turkish\"] Bu olgu sunumu, yüksek mortalite oranına sahip nadir ve yıkıcı bir yaralanma olan travmatik hemipelvektominin yönetimine ışık tutmaktadır. 12 yaşında erkek hasta araç dışı trafik kazasında meydana gelen bir degloving yaralanması nedeniyle dış merkezde sağ alt ekstremite amputasyonu ve sağ hemipelvektomi geçiren geçirdi.

Introduction In patients undergoing limb-salvage internal hemipelvectomy, pelvic ring reconstruction is mandatory to maintain the stability of the pelvis and the spinal column, which finally expected to achieve a good functional outcome. However, no optimal reconstruction method has been established. In addition, no previous reports have highlighted the long-term complications of pelvic ring reconstruction after internal hemipelvectomy. We aimed to analyze the outcome of pelvic ring reconstruction using a double-barreled free vascularized fibula graft (VFG) after internal hemipelvectomy with special reference to long-term complications. Materials and methods We conducted a retrospective review of 9 consecutive patients (5 male, 4 female; mean age 31 years) who underwent pelvic ring reconstruction using a double-barreled free VFG after internal hemipelvectomy (P1, n  = 4; P1 + 4, n  = 3; P1 + 2, n  = 2) at our institution between 1998 and 2013. The mean follow-up period was 55 months (range 3–131 months). Results The mean length of the bone defect was 9 cm. The methods of fixation included a Cotrel-Dubosset rod ( n  = 4), screw ( n  = 3), and screw and plate ( n  = 2). Bone union was achieved in 5 of 8 patients (63 %) over a 1-year follow-up. The mean period required for bone union was 5.4 months (range 3–7 months). There were 3 early postoperative complications: 2 deep infections resulting in graft removal and 1 implant failure resulting in non-union. Among 3 patients, 2 developed scoliosis within 5 years. One patient developed lumbar disc hernia as a result of scoliosis, for which surgical intervention was required. The mean Musculoskeletal Tumor Society score was 57 % at the last follow-up. Conclusions In conclusion, this reconstruction method can achieve an early and high rate of bone union and provide good functional outcome. However, follow-up with careful attention to postoperative complications, including deep infection in the early postoperative period and spinal deformity in the long term, is necessary.

Background During pelvic Sarcoma resections, Surgeons often struggle to obtain negative margins while minimizing collateral damage and maintaining limb function. These complications are usually due to the complex anatomy of the pelvis. Here we present an accurate 3D surgical approach, including pre-operative printing of models and intraoperative patient-specific instruments (PSIs) for optimizing pelvic sarcoma resections. Methods This single-center retrospective study ( N  = 11) presents surgical, functional, and oncological outcomes of patients (average age 14.6 +/− 7.6 years, 4 males) who underwent pelvic sarcoma resections using a 3D surgical approach between 2016 and 2021. All patients were followed up for at least 24 months (mean = 38.9 +/− 30.1 months). Results Our results show promising surgical, oncological, and functional outcomes. Using a 3D approach, 90.9% had negative margins, and 63.6% did not require reconstruction surgery. The average estimated blood loss was 895.45 ± 540.12 cc, and the average surgery time was 3:38 ± 0.05 hours. Our results revealed no long-term complications. Three patients suffered from short-term complications of superficial wound infections. At 24 month follow up 72.7% of patients displayed no evidence of disease. The average Musculoskeletal Tumor Society (MSTS) score at 12 months was 22.81. Conclusion 3D technology enables improved accuracy in tumor resections, allowing for less invasive procedures and tailored reconstruction surgeries, potentially leading to better outcomes in function and morbidity. We believe that this approach will enhance treatments and ease prognosis for patients diagnosed with pelvic sarcoma and will become the standard of care in the future.

BackgroundAlthough internal hemipelvectomies with sacroiliac resections are not traditionally reconstructed, surgeons are increasingly pursuing pelvic ring reconstruction to theoretically improve stability, function, and early ambulation. This study aims to systematically compare complications and functional and oncologic outcomes of sacroiliac resection with and without reconstruction.MethodsPubMed and MEDLINE were queried for studies published between January 1990 and October 2020 pertaining to sacroiliac neoplasm resection with subsequent reconstruction. Patient demographics, histopathologic diagnoses, reconstruction techniques, Musculoskeletal Tumor Society (MSTS) functional scores, and oncologic outcomes were pooled.ResultsTwenty-three studies (201 patients) were included for analysis. Reconstruction was performed in 79.1% of patients, most commonly with nonvascularized autografts (45.8%). The overall complication rate was 54.8%; however, resection followed by reconstruction demonstrated significantly higher complication (62.3% versus 25.7%, p < 0.001) and infection rates (13.7% versus 0%, p = 0.020). Mean MSTS functional score trended higher in nonreconstructed patients (82% versus 71.6%).ConclusionsReconstruction after sacroiliac resection produced higher complication rates and poorer physical recovery when compared with nonreconstructed resection. This systematic review suggests that patients without spinopelvic junction instability may experience superior outcomes without reconstruction. Ultimately, the need to reconstruct the pelvic girdle depends on tumor size, prognosis, and functional goals.

BackgroundHip disarticulation and hemipelvectomy are defined as major ablative amputations of the lower limb. Due to the small number of patients, little is known about the outcome and follow-up.AimsWe aimed to assess (1) reasons for performed major ablative surgeries such as hip disarticulation and hemipelvectomy in a German center for trauma and orthopedic surgery. (2) In addition, mortality and quality of life after hip disarticulation and hemipelvectomy as well as (3) patient and treatment characteristics should be investigated.MethodsDuring a period of twelve years, 15 patients underwent hip disarticulation or hemipelvectomy. Mortality, EQ-5D-3L quality of life by EQ-5D-3L and time-trade-off (TTO), VAS, cause of disarticulation, length of hospital stays, revisions, comorbidities, Charlson comorbidity index (CCI), and ASA score were evaluated retrospective for all patients.ResultsThe overall mortality rates were 26.7% at 30 days, 60.0% after one year and 66.7% after three years. The five surviving patients reported about moderate problems in the EQ-5D-3L. The average VAS score reached 45 (range 15–65). The mean TTO was 9.8 (range 6–12). Indications for amputation were infection (n = 7), tumor (n = 6), trauma (n = 1) and ischemia (n = 1).ConclusionHip disarticulation and hemipelvectomy are followed by a high postoperative mortality. Quality of life of the affected patients is impaired in long-term follow-up. Especially amputations performed due to infections show high mortality within one month after surgery despite average young age and low CCI. Surgeons should be aware of this devastating outcome and extraordinary vigilant for these vulnerable patient cohorts.

PurposeFirst time examination of the physical and psychological long-term outcome following traumatic hemipelvectomy.MethodologyIn this study, all patients suffering from traumatic hemipelvectomy that were treated in a level-A trauma center since 1988 were retrospectively evaluated. The authors aimed to compare the physical and psychological outcome following primary amputation (A) vs. limb-preservation (LP) procedures. The patients were examined with a focus on pain, function, mobility and general health. As part of this examination, various scores were recorded, i.e., Majeed Score, Time up & Go or SF-36.ResultsThe following work showed 13 patients who had suffered a traumatic hemipelvectomy, 8 of whom survived. Five of these were available for subsequent clinical re-examination; of these, three patients underwent an amputation, while limb preservation was performed on two patients. Mean follow-up of the amputee group was after 12 years compared to 6.5 years following limb preservation. After limb preservation, both patients reported phantom limb pain at the affected leg, despite pain medication. The general state of health was assessed as 82/100 (A) and 45/100 (LP). The Majeed score was 61 (A) vs. 45 (LP). In the clinical examination, three out of five patients (2 LP, 1 A) showed peroneal palsy (PP). In the quality-of-life analysis based on the SF12/36 and the NHP, amputees scored higher than the patients who underwent limb preservation surgery.ConclusionIn our small patient cohort, satisfaction, pain and mobility tend to be better following primary amputation compared to limb preserving surgery.

Purpose Resection of pelvic bone tumours and subsequent pelvic girdle reconstruction pose formidable challenges due to the intricate anatomy, weight-bearing demands, and significant defects. 3D-printed implants have improved pelvic girdle reconstruction by enabling precise resections with customized guides, offering tailored solutions for diverse bone defect morphology, and integrating porous surface structures to promote osseointegration. Our study aims to evaluate the long-term efficacy and feasibility of 3D-printed hemipelvic reconstruction following resection of malignant pelvic tumours. Methods A retrospective review was conducted on 96 patients with primary pelvic malignancies who underwent pelvic girdle reconstruction using 3D-printed custom hemipelvic endoprostheses between January 2017 and May 2022. Follow-up duration was median 48.1 ± 17.9 months (range, 6 to 76 months). Demographic data, imaging examinations, surgical outcomes, and oncological evaluations were extracted and analyzed. The primary endpoints included oncological outcomes and functional status assessed by the Musculoskeletal Tumor Society (MSTS-93) score. Secondary endpoints comprised surgical duration, intraoperative bleeding, pain control and complications. Results In 96 patients, 70 patients (72.9%) remained disease-free, 15 (15.6%) had local recurrence, and 11 (11.4%) succumbed to metastatic disease. Postoperatively, function improved with MSTS-93 score increasing from 12.2 ± 2.0 to 23.8 ± 3.8. The mean operating time was 275.1 ± 94.0 min, and the mean intraoperative blood loss was 1896.9 ± 801.1 ml. Pain was well-managed, resulting in substantial improvements in VAS score (5.3 ± 1.8 to 1.4 ± 1.1). Complications occurred in 13 patients (13.5%), including poor wound healing (6.3%), deep prosthesis infection (4.2%), hip dislocation (2.1%), screw fracture (1.0%), and interface loosening (1.0%). Additionally, all patients achieved precise implantation of customized prosthetics according to preoperative plans. T-SMART revealed excellent integration at the prosthesis-bone interface for all patients. Conclusion The use of a 3D-printed custom hemipelvic endoprosthesis, characterized by anatomically designed contours and a porous biomimetic surface structure, offers a potential option for pelvic girdle reconstruction following internal hemipelvectomy in primary pelvic tumor treatment. Initial results demonstrate stable fixation and satisfactory mid-term functional and radiographic outcomes.

Abstract Background Metastatic lesions localized in the pelvis cause pain, pathological fractures and decrease quality of patients life. Limited data are avaliable to compare the oncological, surgical and functional outcomes after different surgeries in patients with metastatic pelvic tumors. Most of the works presents the results of hemipelvectomy performed in patients with primary malignant bone tumors. The objectives of this study were to assess the outcome of patients after internal hemipelvectomy due to cancer metastases. Methods Over the period 2010–2015 at the Department of Orthopaedic Oncology in Brzozów, 34 patients with metastases to the pelvis were treated. This study group comprised of 21 men and 13 women. The mean age was 67 (range: 51–79) for men and 56 (range: 41–77) for women. The majority of the treated patients suffered from myeloma (12 patients) and breast cancer (8 patients). Following the Enneking system classification guidelines, tumours were found in zone I (5 cases), zone II (18 cases), zone III (4 cases). Tumour involvement of both zones (II and III) considered 7 patients. The following resections were accomplished: wide in 11 cases, marginal in 17 cases, and intralesional in 6 cases. 18 patients were postoperatively treated with 8 Gy single-dose radiotherapy. 25 patients underwent bone reconstruction using either Lumic prostheses (9 cases) or the Harrington technique (16 cases). The mean follow-up period was 2.1 years (range: 1.2–6 years). The analysis covered patients’ survival, number of local recurrences, functional results and effectiveness of surgical treatment, considering the type, number and reason of complications. Results Eight patients died. Overal survival calculated with Kaplan- Meier curve was 48.2% for 34 patients. Mean survival was 3.85 years. There were no statistically significant differences in overall survival depending on the type of metastasis resection. In this group, local tumour recurrences concerned 6 patients. The extent of tumour resection and the use of postoperative radiotherapy were statistically significantly related to local recurrences. Functional results were better in a group of patients without reconstruction. Postoperative VAS score was 2.7, Karnofsky status 71 and MSTS 23(86%). After Lumic prostheses implantation VAS score was 3.4, Karnofsky status 65 and MSTS 19(63%). The worst results were observed after Harrington procedure. We noticed 9 perioperative complications in 6 (18%) of patients. Most frequently, the problems included impaired wound healing due to infection (4 patients) and dislocation of Lumic prosthesis (2 patients). Conclusions The frequency of local recurrences after hemipelvectomies is related to the radicality of tumour resection and the postoperative application of radiotherapy. Survival time depends on the type and stage of cancer and does not depend on the type of tumour resection. The best functional results were obtained in patients after type I resection followed by no reconstruction of the bone. Lumic prosthesis implantation gave better results than Harrington procedure.

Background The T-incision approach for internal hemipelvectomy necessitates extensive dissection to expose the posterior pelvic structures, leading to higher rates of wound complications. A modified separated-incision approach was developed and validated in this comparative study. Patients and methods The separated-incision approach used two distinct incisions: an anterior incision that combines the ilioinguinal approach with a short, straight Smith-Petersen incision; and a separated posterior incision for the posterior pelvic structures. This approach was applied to 8 patients with internal hemipelvectomy related to type II + III regions. Seventeen patients underwent a traditional T-incision approach during the same period were matched for comparison. Results The separated-incision approach was successfully performed in these eight patients, preserving the gluteal vessels and posterior skin-muscle flap. Lower blood loss (2375 vs. 3952 mL, p  = 0.005), and similar operative time (312 vs. 398 min, p  = 0.098) was observed. Postoperative haemoglobin was higher (88.1 vs. 74.8 g/L, p  = 0.009), and drainage volumes were marginally reduced (1379 vs. 1917 mL, p  = 0.209). Compared to 8 patients in the T-incision group who experienced wound complications including delayed wound healing ( n  = 4) and surgical site infection ( n  = 4), all patients in separated-incision group achieved primary wound healing within 3 weeks (47% vs. 0%, p  = 0.026). Additionally, they had a shorter time to ambulation (39 vs. 62 days, p  = 0.015) and higher MSTS scores (24.25 vs. 20.47, p  = 0.006). No differences were observed in local recurrence or overall survival. Conclusions The separated-incision demonstrated fewer wound complications and faster mobilization, suggesting it is a promising alternative; multicentre validation is warranted.

Background Surgical treatment of pelvic tumors with or without acetabular involvement is challenging. Primary goals of surgery include local control and maintenance of good quality of life, but the procedures are marked by significant perioperative morbidity and complications. Questions/purposes We wished to (1) evaluate the frequency of infection after limb salvage surgical resection for bone tumors in the pelvis; (2) determine whether infection after these resections is associated with particular risk factors, including pelvic reconstruction, radiotherapy or chemotherapy, type of resection, and age; and (3) analyze treatment of these infections, particularly with respect to the need of additional surgery or hemipelvectomy. Methods From 1975 to 2010, 270 patients with pelvic bone tumors (149 with chondrosarcoma, 40 with Ewing’s sarcoma, 27 with osteosarcoma, 18 with other primary malignant tumors, 11 with metastatic tumors, and 25 with primary benign tumors) were treated by surgical resection. Minimum followup was 1.1 years (mean, 8 years; range, 1–33 years). The resection involved the periacetabular area in 166 patients. In 137 patients reconstruction was performed; in 133 there was no reconstruction. Chart review ascertained the frequency of deep infections, how they were treated, and the frequency of resection arthroplasty or hemipelvectomies that occurred thereafter. Results A total of 55 patients (20%) had a deep infection develop at a mean followup of 8 months. There were 20 infections in 133 patients without reconstruction (15%) and 35 infections in 137 patients with reconstruction (26 %). Survivorship rates of the index procedures using infection as the end point were 87%, 83%, and 80% at 1 month, 1 year, and 5 years, respectively. Infection was more common in patients who underwent pelvic reconstruction after resection (univariate analysis, p = 0.0326; multivariate analysis, p = 0.0418; odds ratio, 1.7718; 95% CI, 1.0243–3.0650); no other risk factors we evaluated were associated with an increased likelihood of infection. Despite surgical débridements and antibiotics, 16 patients (46%) had the implant removed and five (9%) underwent external hemipelvectomy (four owing to infection and one as a result of persistent infection and local recurrence). Conclusions Infection is a common complication of pelvic resection for bone tumors. Reconstruction after resection is associated with an increased risk of infection compared with resection alone, without significant difference in percentage between allograft and metallic prosthesis. When infection occurs, it requires removal of the implant in nearly half of the patients who have this complication develop, and external hemipelvectomy sometimes is needed to eradicate the infection.
