Abstract
Primary sarcomas of bone are rare malignant mesenchymal tumors. The most common bone sarcomas are osteosarcoma, Ewing's sarcoma, and chondrosarcoma. The prognosis has improved over the years, but bone sarcomas are still life-threatening tumors that need a multidisciplinary approach for diagnosis and treatment. Bone sarcomas arising in the pelvis present a unique challenge to orthopedic oncologists due to the absence of natural anatomical barriers, the close proximity of vital neurovascular structures, and the high mechanical demands placed on any pelvic reconstruction following the excision of the tumor. While radiotherapy has an important role especially in Ewing's sarcoma and chemotherapy for both Ewing's sarcoma and osteosarcoma, surgery remains the main choice of treatment for all three entities. While external hemipelvectomy has remained one option, the main aim of surgery is limb salvage. After complete tumor resection, the bone defect needs to be reconstructed. Possibilities to reconstruct the defect include prosthetic or biological reconstruction. The method of reconstruction is dependent on the location of tumor and the surgery required for its removal. The aim of this article is to give an insight into pelvic bone sarcomas, their oncological and surgical outcomes, and the options for treatment based on the authors' experiences.

Surg Oncol 2023; 48:101923. [PMID: 36931178 DOI: 10.1016/j.suronc.2023.101923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 02/21/2023] [Accepted: 03/05/2023] [Indexed: 03/13/2023]
Abstract
INTRODUCTION Surgery of primary malignant tumors involving the sacroiliac joint requires wide resection, which often interrupts the pelvic ring. Nowadays, restoration of the pelvic ring to provide stability and which technique is most fitting remain subject to debate. The aim of this study is to evaluate the results of pelvic reconstruction with pedicle screw instrumentation and tibial allograft following Enneking Type I-IV resections. PATIENTS AND METHODS All patients who underwent reconstruction with tibial allograft, screws and rods after resection of areas I and IV for primary bone tumors between 2017 and 2022 were reviewed. Clinical and radiological characteristics, fusion rate and functional results were analyzed. The MSTS score and the TESS were used to evaluate functional results. RESULTS Seven patients were included in the study. Chondrosarcoma was the most common histology. Only four patients reported pain. No fractures were observed at tumor diagnosis. Computer-assisted navigation was used in six cases. Reconstruction was performed in four cases with a screw inserted in the homolateral L5 pedicle and in the ischium, in two cases with a screw in the homolateral L4 pedicle and another in the homolateral L5 pedicle, in the last case with two screws inserted in L4 and L5, one screw in the ischium and another one in the residual iliac wing. In this case a contralateral stabilization was also carried out. The spine screws and the iliac screws were connected with a rod. The mean follow-up for all 7 patients was 37 months. One patient (16.6%) died due to general complications not directly related to the surgery; while the others are alive and apparently free of disease. Complete fusion was obtained in four out of seven patients and the average time for fusion was 9 months. The average MSTS score and TESS were 58.7% and 57.8%, respectively. DISCUSSION The need for reconstruction is thoroughly debated in literature. The advantages of restoring posterior pelvis stability are the prevention of long-term pain associated with limb shortening and secondary scoliosis. Re-establishment of the pelvic ring can be achieved through synthetic, biologic or hybrid reconstructions. CONCLUSIONS More studies that assess the surgical consequences at long-term follow-up and help clarify the indications for reconstruction and the specific technique are necessary to confirm our preliminary results.

BMC Musculoskelet Disord 2021; 22:405. [PMID: 33941162 PMCID: PMC8091684 DOI: 10.1186/s12891-021-04294-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 04/14/2021] [Indexed: 02/08/2023] Open
Abstract
Background Pubic defects resulting from type III hemipelvectomy are commonly not reconstructed due to the need to preserve the weight-bearing axis. However, the opening of the anterior pelvic ring will inevitably lead to increased pelvic instability. To improve long-term pelvic stability, three-dimensional (3D)-printed customized prostheses were designed to reconstruct pubic defects. This study presents and evaluates the short-term clinical outcomes and complications from the use of this construct. Methods Five patients who underwent type III hemipelvectomy and 3D-printed customized prosthesis reconstruction at our institution between 2017 and 2019 were retrospectively analysed. Operation time and blood loss during the operation were recorded. Local and functional recovery was assessed. Prosthetic position and osseointegration were evaluated. Oncology results and complications were recorded. Results The prostheses consisted of three with stems and two without. The mean follow-up time was 23.6 months. At the last follow-up, all five patients were alive with no evidence of disease. No deep infections or local recurrence had occurred. The mean blood loss and mean intraoperative time were 1680 ml and 294 min, respectively. The mean functional MSTS score at the final follow-up was 29.8. Fretting wear around the prosthetic stem was found in 3 patients, while bone wear on the normal-side pubis was found in 2 patients. Osseointegration was observed in all patients. Conclusions 3D-printed customized prostheses for reconstructing pubic bone defects after type III hemipelvectomy showed acceptable early outcomes. The good outcomes were inseparable from the precision prosthesis design, strict surgical procedures, and sensible postoperative management.

Abstract
Proper selection of patients, preoperative planning and wide surgical margins with reconstruction provides good local control and clinical outcomes following pelvic resection. Patient with huge tumor need large amount of blood transfusion and postoperative intensive care due to longer surgery time. The surgical site infection is common complication after pelvic resection and can be managed with debridement and antibiotic therapy.
Introduction Patients with osteochondromatosis have a higher risk of malignant transformation into secondary chondrosarcoma. Chondrosarcoma at the pelvic region tends to present late and therefore pose a significant challenge for orthopedic surgeons because of the large tumor size, local extension, and complex anatomy with proximity to major neurovascular structure, intestinal and urinary tract. Presentation of case A 44-year-old male presented the chief complaint of 15 years growing lumps on his left buttock and right groin, presenting with pain. Plain radiography revealed popcorn calcification at the left iliac wing and right superior pubic rami. Multiple exostoses were also visible. MRI showed a larger tumor diameter at the left iliac wing by 33 cm and right pubic rami by 13 cm. The histopathological result from the biopsy suggested low-grade chondrosarcoma. Result The patient underwent pelvic resection type I and III in two-stage surgery. About one month after the first surgery, there was a postoperative infection. Debridement and antibiotic therapy resulted in a desirable functional outcome with an MSTS score 27 and no local recurrence sign during a one-year follow-up. Discussion Low-grade chondrosarcomas are not sensitive to radiation and chemotherapy; wide surgical resection is the mainstay of treatment. Chondrosarcoma at the iliac wing can be treated by pelvic resection type I, and further reconstruction needed to prevent pelvic tilting. Chondrosarcoma at pubic rami can be treated by pelvic resection type III. Conclusion Proper patient selections, preoperative planning, and wide surgical margins with reconstruction provide desirable local control and clinical outcomes following pelvic resection.

Abstract
Background This study is to describe the detailed design and surgical techniques of three-dimensional (3D)-printed customized prosthesis for pubic bone defect. Patients and methods Five patients under type III resections were included in this study. Based on radiography data, 3D pelvic model was established and virtual surgery was simulated. Detailed anatomy data were measured including the size and arc of normal pubis, the size of residual bone in acetabular side. Different fixation ways were considered according to shape of defect. After features modification and porous structure design, prostheses were fabricated. The osteotomy guides and plastic models were used during surgery. Result Of 5 cases, the prostheses consist of the type with stem (3, 60%) and the type without stem (2, 40%). Mean follow-up period was 13.6 months (range, 8-24 months). For partial pubis removed cases, the mean length and width of narrowest part of normal superior pubis were 13.19 mm (range, 12.51-14.12 mm) and 7.80 mm (range, 7.18-8.26 mm) respectively. Mean arc of normal pubis was 2.71 rad (range, 2.66-2.73 rad). For the entire pubis resection cases, the mean diameter of narrowest parts and length of normal superior pubis were 11.52 mm (range, 11.13-11.91 mm) and 64.78 mm (range, 63.46-66.09 mm), while the diameter of narrowest part and length of normal inferior pubis were 7.37 mm (range, 7.20-7.54 mm) and 86.43 mm (range, 84.28-88.57 mm). Mean length and arc of intramedullary stem was 20 mm (range, 18-21 mm) and 2.7 rad. Mean screw holes number was 6.3 (range, 6-7) while ultimate screws number in surgeries was 4.3 (range, 4-5). Porous structure with 600-μm-pore size and 70% porosity was applied in parts of contact with residual bone. Conclusion 3D-printed customized prostheses could be a feasible option to reconstruct bone defect after type III resection. The design of 3D-printed customized prostheses is a multi-step process which is based on strict anatomic measurement.

Abstract
As reconstructive needs often extend past the soft tissue alone, a plastic surgeon must also be well versed in the methods of bony reconstruction. Understanding of the basic science of fracture healing and the biochemical mechanisms of the different bone grafts, bone substitutes, and orthobiologics is essential to selecting among the many different options available to the modern plastic surgeon. This review provides a broad overview of these different options and the specific applications for plastic surgeons based on anatomic location.

Abstract
In this study, a multi-objective topology optimization method has been formulated and carried out for various resection types, with minimization of a weighted sum of the compliance (maximized stiffness) under six routine activities of daily life as the objective function and volume reduction as a constraint. Unique prosthetic geometries with low weight and remarkable strength closely matching the pelvic bone shape were obtained. The strength of the optimized implants was investigated through finite element analysis and it has been found that the initial geometries of the optimized implants could withstand the static loading conditions of various routine activities having less stress concentration areas. A 3D printed patient-specific topology optimized hemi-pelvic prosthesis has been designed based on the proposed method and implanted successfully in a patient with pelvic sarcoma. Therefore, pelvic prostheses can be designed and then manufactured via additive manufacturing technologies with the minimum material in less time and having robust mechanical fixation responses. Conclusively, the topology optimization method used for the design of pelvic prostheses improves the biomechanical performance of the implants with reduced weight and higher stiffness than the traditional implants. Including the topology optimization procedure in the phase of designing patient-specific pelvic implants is therefore, highly recommended.

Abstract
Objective: Hemipelvectomy is a complex surgery with a high complication rate. Here, we aimed to identify factors related to the onset of complications and calculate their impacts on hospital costs. Methods: We evaluated 31 consecutive patients who underwent hemipelvectomy between 1999 and 2015. We assessed the clinical and radiographic data to determine the patients’ demographic factors, tumor and surgical characteristics, and complications. The individual hospital stays and financial balances were assessed up to 6 months following the index surgery. Results: The overall complication rate was 61% (19/31). Infection was the most prevalent complication (36%). Immediate postoperative death occurred in 5/31 patients (16%); another 5 (16%) died after hospital discharge due to disease progression. Histological grade, previous surgery, and previous radiotherapy were not associated with complications or infection. Acetabular resections, bone reconstruction, and longer operative times were associated with infection, whereas older age, pelvic organ involvement, and comorbidities were associated with immediate postoperative death. Complications and infection were associated with 4.8- and 5.9-fold increases in hospital costs, respectively. Conclusions: Acetabular resection and bone reconstruction are important factors that increase short-term complication rates, infection rates, and hospital costs. Mortality was associated with older age and adjacent pelvic tumor progression. Level of Evidence: IV, case series.

The usefulness of wide excision assisted by a computer navigation system and reconstruction using a frozen bone autograft for malignant acetabular bone tumors: a report of two cases. BMC Cancer 2018; 18:1036.

Abstract
Background Difficult resection of tumors from regions with complex local anatomy, such as the pelvis and sacrum, is likely to result in inadequate surgical margins (intralesional or marginal); this is because three-dimensional osteotomy is difficult particularly around the acetabulum. Additionally, removal of the joint makes reconstruction very difficult; thus, retention of good function also becomes difficult. In musculoskeletal oncology, computer navigation systems are still not widely used to prevent tumor-positive margins. We performed wide excision with guidance from a computer navigation system and reconstruction using frozen bone autografts for malignant pelvic bone tumors in two patients, and we obtained excellent functional and oncological outcomes. Here we present these patients and discuss our approach. Case presentation Case 1: A 12-year-old girl presented with Ewing sarcoma of the left pelvis (PI-II). We performed wide excision assisted by a computer navigation system with the osteotomy of the load surface of acetabulum and reconstruction using a frozen bone autograft. At the final follow-up, she showed excellent function and was alive without the disease. Moreover, she did not have osteoarthritis of the left hip joint. Case 2: A 71-year-old woman presented with dedifferentiated chondrosarcoma of the right pelvis (PII-III). We performed wide excision assisted by a computer navigation system with osteotomy avoiding load surface of the acetabulum and reconstruction using a frozen bone autograft; there was no tumor at the load surface. At the final follow-up, she showed good function, was alive without the disease, and did not have osteoarthritis of the left hip joint. Conclusions Wide excision assisted by a computer navigation system and reconstruction using a frozen bone autograft are very useful for the management/treatment of extremely difficult cases such as malignant pelvic bone tumors, particularly those including the acetabulum.

Oncotarget 2018; 8:38978-38989.

Abstract
The mechanical outcomes of patients with pelvic bone tumors involving zone I or zone I + IV who received resection and different reconstructions are not clear. Therefore, the purpose of this study was to compare the outcomes of different rod-screw systems in reconstruction for these patients, and evaluate the relative risk of mechanical failure for them. We reviewed 30 patients for a mean duration of 40.4 months of follow-up (range, 13.1–162.2 months), five patients had mechanical complications. The mechanical survival rate of two-rod and four-screw (TRFS) group was significantly higher than one-rod and two-screw (ORTS) group (p = 0.000). The implant survival rate was correlated with ages (p = 0.010), younger people are more likely to fail. Thus, TRFS fixation for pelvic reconstruction after Enneking type I/I + IV resection can provide better short to long-term mechanical stability compared with ORTS fixation, the strength of ORTS fixation is not enough. In addition, biological reconstruction such as autologous bone graft is recommended for the patients who are younger or suffered from benign tumor. As for the patients who are older, with malignant tumors, underwent adjuvant radiotherapy or chemotherapy, functional reconstruction with bone cement is a good choice.

Abstract
BACKGROUND Reconstruction of iliosacral defects following oncologic resection is a difficult clinical problem associated with a high incidence of failure. Technical approaches to this problem are heterogeneous and evidence supporting specific techniques is sparse. Maximizing construct stability may improve union rates and functional outcomes. The purpose of this study is to compare construct stiffness, load to failure, and mechanism of failure between two methods of iliosacral reconstruction in an ex-vivo model to determine if either is mechanically superior. METHODS Eight third-generation composite pelves reconstructed with a plate-and-screw technique were tested against seven pelves reconstructed with a minimal spinal instrumentation technique using axial loading in a double-leg stance model. FINDINGS The pelves from the plate group demonstrated higher stiffness in the direction of applied load (102.9 vs. 66.8N/mm; p=0.010) and endured a significantly larger maximum force (1416 vs. 1059N; p=0.015) than the rod group prior to failure. Subjectively, the rod-reconstructed pelves were noted to be rotationally unconstrained while pivoting around their single point-of fixation in each segment leading to earlier failure. INTERPRETATION Plate-reconstruction was mechanically superior to spinal instrumentation in the manner performed in this study. More than one point of fixation in each segment should be achieved to minimize the risk of rotational deformation.

Abstract
Background. Periacetabular resections with reconstruction has high rates of complications due to the complexity of the reconstruction. We have improvised a novel technique of reconstruction for type II and type II + III pelvic resections with the use of a commercially available acetabulum reconstruction cage (gap II, Stryker) and threaded rods. Objectives. The aim of our study is to determine the biomechanical strength of our reconstruction compared to the traditional cemented total hip replacement (THR) designs in normal acetabulum and establish its mode of failure. Methods. Five sets of hemipelvises were biomechanically tested (Instron® 3848, MA, USA). These constructs were subjected to cyclic loading and load to failure. Results. The reconstructed acetabulum was stiffer and required a higher load to failure compared to the intact pelvis with a standard THR. The mean stiffness of the reconstructed pelvis was 1738.6 ± 200.3 Nmm−1 compared to the intact pelvis, which was 911.4 ± 172.7 Nmm−1 (P value = 0.01). The mean load to failure for the standard acetabular cup construct was 3297.3 ± 117.7 N while that of the reconstructed pelvis with the acetabulum cage and threaded rods was 4863.8 ± 7.0 N. Conclusion. Reconstruction of the pelvis with an acetabular reconstruction cage and threaded rods is a biomechanical viable option.

Abstract
Hemipelvic resections for primary bone tumours require reconstruction to restore weight bearing along anatomic axes. However, reconstruction of the pelvic arch remains a major surgical challenge because of the high rate of associated complications. We used the pedicle screw-rod system to reconstruct the pelvis, and the purpose of this investigation was to assess the oncology, functional outcome and complication rate following this procedure. The purpose of this study was to investigate the operative indications and technique of the pedicle screw-rod system in reconstruction of the stability of the sacroiliac joint after resection of sacroiliac joint tumours. The average MSTS (Musculoskeletal Tumour Society) score was 26.5 at either three months after surgery or at the latest follow-up. Seven patients had surgery-related complications, including wound dehiscence in one, infection in two, local necrosis in four (including infection in two), sciatic nerve palsy in one and pubic symphysis subluxation in one. There was no screw loosening or deep vein thrombosis occurring in this series. Using a pedicle screw-rod after resection of a sacroiliac joint tumour is an acceptable method of pelvic reconstruction because of its reduced risk of complications and satisfactory functional outcome, as well as its feasibility of reconstruction for type IV pelvis tumour resection without elaborate preoperative customisation. Level of evidence: Level IV, therapeutic study.

Abstract
Objective: To show the experience of the Erasto Gaertner Hospital with hemipelvectomy surgery over a 10-year period. Methods: This was a retrospective study on 32 patients who underwent hemipelvectomy at Erasto Gaertner Hospital between 1998 and 2008, assessing clinical and surgical characteristics. Results: Among the 32 patients, 15 were female and 17 were male. The mean age was 37.94 years. Eight cases showed involvement of the neurovascular bundle: three were located in the iliac and extended to the thigh, two were in the acetabulum and extended to the thigh and three were in the acetabulum and pubis. Twenty-three cases presented a neurovascular bundle free from neoplasia: 11 were restricted to the iliac, six were in the acetabular region, two were in the pubic ramus and four extended to the whole hemipelvis bone. One case involved the iliac-femoral vessels: one in the pubic ramus. Seven cases of chondrosarcoma and four cases of Ewing's sarcoma represented the majority. Eight cases underwent external hemipelvectomy and 24 underwent internal hemipelvectomy (11 were type I; four were type II; two were type II + III; three were type III and four were type IV). Of these 24 cases, 13 did not have any reconstruction, 10 had a fibular graft and one had an iliacfemoral vein and artery prosthesis. Twenty-six surgeries were curative and six were palliative. There were 14 deaths. Survival of two and five years was seen in 11 and 10 cases, respectively. For six cases, less than two years had passed since the operation. Three cases were lost during follow-up. Conclusion: This study shows the experiences of an oncology reference service specializing in highly complex surgical treatment.

Clinical Outcomes of Surgical Treatments for Primary Malignant Bone Tumors Arising in the Acetabulum. Sarcoma 2015; 2015:430576.

Abstract
The functional and oncologic results of eighteen patients with primary malignant periacetabular tumors were reviewed to determine the impact of surgical treatment. The reconstruction procedures were endoprosthesis (11), hip transposition (4), iliofemoral arthrodesis (2), and frozen bone autograft (1). After a mean follow-up of 62 months, 13 patients were alive and 5 had died of their disease; the 5-year overall survival rate was 67.2%. The corresponding mean MSTS scores of patients with endoprosthesis (11) and other reconstructions (7) were 42% and 55% (49%, 68%, and 50%), respectively. Overall, postoperative complications including deep infection or dislocation markedly worsened the functional outcome. Iliofemoral arthrodesis provided better function than the other procedures, whereas endoprosthetic reconstruction demonstrated poor functional outcome except for patients who were reconstructed with the adequate soft tissue coverage. Avoiding postoperative complications is highly important for achieving better function, suggesting that surgical procedures with adequate soft tissue coverage or without the massive use of nonbiological materials are preferable. Appropriate selection of the reconstructive procedures for individual patients, considering the amount of remaining bone and soft tissues, would lead to better clinical outcomes.

Clin Orthop Relat Res 2015; 473:1442-8. [PMID: 25337979 PMCID: PMC4353538 DOI: 10.1007/s11999-014-4009-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2014] [Accepted: 10/07/2014] [Indexed: 01/31/2023]
Abstract
BACKGROUND In patients undergoing hemipelvectomies including resection either of a portion of the pubis or the entire pubis from the symphysis to the lateral margin of the obturator foramen while sparing the hip (so-called Dunham Type III hemipelvectomies), reconstructions typically are not performed given the preserved continuity of the weightbearing axis and the potential complications associated with reconstruction. Allograft reconstruction of the pelvic ring may, however, offer benefits for soft tissue reconstruction of the pelvic floor and hip stability, but little is known about these reconstructions. QUESTIONS/PURPOSES (1) What is the postoperative functional status after allograft reconstruction of Type III pelvic defects? (2) What are the rates of hernia, infection, and hip instability? METHODS In this case series, we reviewed all patients with Type III pelvic resections (with or without anterior acetabular wall resections) who underwent allograft reconstruction between 2005 and 2013 at one center (N = 14). During the period in question, reconstruction was the general approach used in patients undergoing these resections; during that time, three other patients were treated without reconstruction as a result of either surgeon preference or the patient choosing to not have reconstruction after a discussion of the risks and benefits. Of the 14 patients treated with reconstruction, complete followup was available at a minimum of 1 year in 11 (other than those who died before the end of the first year; median, 19 months; range 16-70 months among those surviving), one was lost to followup before a year, and two others had partial telephone or email followup. Patient demographics, disease status, functional status, and complications were recorded. For a portion of the cohort (four patients) later in the series, we used a novel technique for anterior acetabular wall reconstruction using the concave cartilaginous surface of a proximal fibula allograft; the others received either a long bone (humerus or femur) or hemipelvis graft. Seven patients died of disease; two had local recurrence, and five died of metastatic disease. RESULTS All patients remained ambulatory Pain at 12 months after surgery was reported as none in five, mild in two, moderate in two, and severe in one. Operative complications included infection in two, symptomatic hernia in one, hip instability in one, dislocated total hip arthroplasty on the first postoperative day in one, and graft failure in one. CONCLUSIONS Allograft reconstruction after Type III pelvic resections can provide functional reconstruction of the pelvic ring, pelvic floor, and, in certain patients with partial anterior acetabular resections, the resected anterior acetabulum. This has implications in preventing the occurrence of hernia and hip instability in this patient population that is classically not reconstructed, although longer-term outcomes in a larger number of patients would help to better delineate this because infection, hernia, hip instability, and graft nonunion still remain concerns with this approach. The most important unanswered question remains whether, on balance, any benefits that may accrue to these patients as the result of reconstruction are offset by a relatively high likelihood of undergoing secondary or revision surgery.

Abstract
Background The aim of this study was to evaluate the reliability of open reduction and minimally invasive plate osteosynthesis (MIPO) for anterior ring fracture combined with pubic symphysis separation and to explore the operative techniques and therapeutic efficacy. Material/Methods We used minimally invasive plate osteosynthesis (MIPO) to treat anterior ring fracture combined with pubic symphysis separation. Results During postoperative follow-up, all patients recovered well, with no fat liquefaction, infection, femoral nerve or iliac blood vessels injury, deep vein thrombosis, heterotopic ossification, or any and other complications. Conclusions The MIS or MIPPO for anterior ring fracture combined with pubic symphysis separation has the advantages of short operation time and less blood loss. This clinical operation is safe and feasible, with therapeutic efficacy.

Abstract
This is a technical note of pelvic reconstruction performed by an advanced multidisciplinary team. The authors report a new 3-stage reconstruction of the hemipelvis after Type 3 sacrectomy involving instrumented spinoiliac arthrodesis and pedicled fibula grafting in 2 patients.
The anterior stage of the procedure begins with a transabdominal approach to mobilize the viscera and to free up the tumor from the vessels. The posterior divisions of internal iliac vessels, the middle sacral vessels, and the lateral sacral vessels are then ligated. An anterior vertebrectomy is done at the appropriate level, followed by an anterior osteotomy through the lateral planed surgical margin of the sacrum close to the salvaged sacroiliac joint. The second stage includes a major sacral resection with lower-extremity amputation from the pubic symphysis through the intact side of the sacrum, ipsilateral pedicled fibula harvesting, and closure with an ipsilateral pedicled quadriceps flap. The final stage involves reconstruction with lumboiliac instrumentation. The pedicled fibular graft left from the second stage is then placed distally within the previously created iliopectineal docking site and proximally within the L-5 docking site.
The authors believe that this is a feasible and reproducible technique with theoretical advantages that have to be proved in the long-term follow-up.

Abstract
OBJECTIVES : Pelvic reconstruction after tumor resection is challenging. METHODS A retrospective study had been preformed to compare the outcomes among patients who received pelvic reconstructive surgery with allogeneic bone graft after en bloc resection of pelvic tumors and patients who received en bloc resection only. RESULTS Patients without reconstruction had significantly lower functional scores at 3 months (10 vs. 15, P = 0.001) and 6 months after surgery (18.5 vs. 22, P = 0.0024), a shorter duration of hospitalization (16 day vs. 40 days, P < 0.001), and lower hospitalization costs (97,500 vs. 193,000 RMB, P < 0.001) than those who received pelvic reconstruction. Functional scores were similar at 12 months after surgery (21.5 vs. 23, P = 0.365) with no difference in the rate of complications between the two groups (P > 0.05). CONCLUSIONS : Pelvic reconstruction with allogeneic bone graft after surgical management of pelvic tumors is associated with satisfactory surgical and functional outcomes. Further clinical studies are required to explore how to select the best reconstruction method. Level of Evidence IV, Case Series.

Abstract
BACKGROUND Posterior pelvic ring reconstruction can be challenging and controversial. The choice regarding whether to reconstruct and how to reconstitute the pelvic ring is unclear. Many methods provide stability but often are technically difficult and require excessive dissection. DESCRIPTION OF SURGICAL TECHNIQUE: This unique reconstructive technique uses the anterior aspect of the iliac crest with its attached muscle pedicle to provide a biologic scaffold for healing. The construct is secured with pedicle screws into the posterior column and S1 vertebral body with a spinal rod locked in compression. No additional fixation is used proximally into the lumbar spine. The iliac crest remains attached to the gluteus medius, allowing potential abductor function. METHODS We retrospectively reviewed six patients who underwent iliosacral resection with this reconstruction. The mean age of the patients was 41 years. Complications were recorded. One patient died 6 months postoperatively. Musculoskeletal Tumor Society 1993 (MSTS '93) score and Toronto Extremity Salvage Score (TESS) were obtained at a minimum 1-year followup in five patients. Healing was assessed radiographically. The minimum followup was 6 months (median, 33 months; range, 6-53 months). RESULTS The mean MSTS '93 score was 72% and mean TESS was 66. All posterior column graft sites healed. At last followup, four of the five surviving patients had a stable pseudarthrosis at the proximal sacral site. One patient had a local recurrence and experienced failure of instrumentation without collapse or rotation of the hemipelvis 3 years postoperatively. CONCLUSIONS This technique provides a simple way to reconstruct the pelvic ring after iliosacral resection with clinical outcomes comparable to those for other methods. The method is a potential alternative for reconstruction of the posterior pelvic ring after resecting the ilium although reliable healing of the sacral site needs to be improved.

Abstract
BACKGROUND Iliosacral resection of pelvic malignant tumors and subsequent reconstruction have tested the ingenuity of orthopedic oncologists because of the difficulty of oncological wide resection and the complex biomechanics of the sacroiliac joint render reconstruction challenging. This study compared the functional and surgical outcomes of a biological reconstruction technique with the lack of reconstruction following iliosacral resection. METHODS Twenty-six consecutive cases with malignant iliac tumors involving the sacrum were retrospectively reviewed. These cases underwent iliosacral resection (type I/IV) followed by no reconstruction or a biological reconstruction blinded to authors between 1997 and 2007. After iliosacral resection, 12 cases underwent reconstruction with nonvascular fibular grafts and plate and/or pedicle screw-rod; the other 14 cases did not undergo reconstruction. RESULTS The median follow-up was 84.42 (range, 32-165) months. The local recurrence rate in the reconstruction group was 8.33 % (1/12) with 14.29 % (2/14) in the group without reconstruction. The functional score of the biological reconstruction group was significantly higher than that of the no-reconstruction group as determined by Student's t test. In the biological reconstruction group, bone fusion occurred in 91 % of cases and fibula hypertrophy was observed in 41.7 %. Complications included sciatic nerve palsy, broken screws, intractable pain, nonunion, pelvic oblique, and leg-length discrepancy. CONCLUSIONS After iliosacral resections of pelvic malignant tumors, the biologic reconstruction of these defects could restore spinopelvic stability and continuity. The double-barrel fibular autograft combined with the plate or pedicle screw-rod system is an effective reconstruction method for both optimal short- and long-term stability.

Abstract
Background and Objectives. Hemipelvectomy is a major surgical procedure that associates with significant morbidity, functional impairment, and psychological and body image problem. Reconstruction of the defect is a challenged since a large amount of composite tissues are needed. We would like to share our eight-year experience with massive pelvic resection and reconstruction.
Methods. A retrospective analysis of all cases of hemipelvectomy was conducted in our institution over eight-year period with particular attention given to the reconstruction choices and associated complications. Results. Thirteen patients were included with median age of 39 years (range 13–78) of which all had advanced tumour with stage IIb (54%) and Stage III (46%). External hemipelvectomy was performed in all cases, and resultant defects were reconstructed with variety type of flaps. These include fillet thigh flaps, regional pedicle flaps of different designs, and free flap. Conclusions. Massive pelvic tumour is rarely encountered in our population but can be seen across all age groups and usually due to late presentation. The defects should be reconstructed using local or regional flaps, incorporating the muscle component to enhance flap perfusion. The tissue should be harvested from the amputated limb, as it can limit the donor site morbidity.

Abstract
STUDY DESIGN Retrospective case series. OBJECTIVE To evaluate the risk of infection, related treatment, and outcome after surgery of the 2 most common primary sacral tumors. SUMMARY OF BACKGROUND DATA Rarity of sacral tumors has limited the number of population-based studies. Treatment depends on malignancy or local aggressiveness: wide resection is indicated for malignant lesions, intralesional surgery for benign. METHODS We studied 82 patients with sacral chordomas (55 cases) or giant cell tumor (GCT) (27 cases) treated between 1976 and 2005. All patients had IV antibiotic therapy with amikacin and teicoplanin. Surgery of chordoma was resection; surgery of GCT was intralesional excision. Infections were classified as immediate postoperative, early (within 6 months), and late (more than 6 months from surgery). Mean follow-up was 9.5 years (range: 3-27 years). Some factors possibly influencing the risk of infection were statistically analyzed by Kaplan Meier curves and log-rank test. RESULTS No deep infections were observed in the GCT series. Three patients with sacral chordoma died for postoperative complications and were excluded from this analysis. Of the remaining 52 patients with chordoma, 23/52 had deep wound infection (44%) that required 1 or more surgical debridements combined with antibiotics, according to cultures. In 16 patients (70%), infection occurred within 4 weeks postoperatively, and in 7 within 6 months. Most frequent bacteria were Enterococcus (23%), Escherichia coli (20%), and Pseudomonas aeruginosa (18%). In 74% of cases, infection was multimicrobial. Level of resection, previous intralesional treatment elsewhere, tumor volume, and age did not statistically influence risk of infection. CONCLUSION Type of surgery was the prominent factor related to a major risk of infection. Operating procedure time correlated as well. Resections of sacral chordoma imply a high risk of deep infection, while intralesional excision of GCT does not. All infections healed with surgical debridements and antibiotic therapy.

Abstract
Pelvic ring disruption after trauma is uncommon, occurring in 20–37/100,000 people in the general population. However, in high velocity poly trauma up to 20% of cases have this injury contributing significantly to morbidity and mortality. The management of pelvic and acetabular trauma has become a subspecialty within the orthopaedic trauma care. The injury patterns are now better understood, there is agreement on a classification system and operative stabilisation has become a viable treatment option.

Abstract
After the first hemipelvectomy in 1891 significant advances have been made in the fields of preoperative diagnosis, surgical technique and adjuvant treatment in patients with pelvic tumors. The challenging surgical removal of these rare malignant bone or soft tissue tumors accompanied by interdisciplinary therapy is mostly the only chance of cure, but bares the risk of intensive bleeding and infection. The reconstruction after hemipelvectomy is of importance for the later outcome and quality of life for the patient. Here, plastic surgery with microvascular free flaps or local rotational flaps improved the reconstruction and reduced infection rates. Average local recurrence rates of 14% demonstrate good surgical results, but 5 year survival rates of only 50% are described for some tumor entities, showing the importance of a multimodal collaboration. On a basis of a selective literature review the history, indications, treatment options and outcome of hemipelvectomies are presented.

Abstract
Vertical shear pelvic ring fractures have been described as being produced only by a force directed cephalad, typically from falls or motor vehicle collisions. We report a seemingly similar vertical injury with the displacement of the hemipelvis being caudad rather than cephalad. Caudad displacement of the hemipelvis might disrupt the pelvic floor and vasculature far more than a standard vertical shear injury would and might be more prone to vascular injury. The clinical examination of the pelvic wound in our patient was not impressive and the magnitude of displacement seen on the admission radiograph was not different from that seen with a typical vertical shear injury. It is the caudal direction of the displacement that we think should alert the surgeon to the possibility of massive vascular injury and potential for limb loss.

Abstract
BACKGROUND We present here the oncological and functional outcomes of limb salvage with or without reconstruction for primary sarcomas in the pelvic bone. METHODS Forty-four patients who underwent pelvic resection for primary sarcomas involving the pelvis were reviewed. The average follow-up period was 39 months (range, 0 to 146 months). Chondrosarcoma (n = 17) and osteosarcoma (n = 10) were the most common diagnoses. Various clinicopathologic factors were analyzed in relation to the oncological outcomes of overall survival and local recurrence. The Musculoskeletal Tumor Society functional scores and complications were compared according to the tumor location, pelvic continuity and the type of resection. RESULTS The overall 5-year survival rate was 40%. Metastasis at the time of diagnosis, the surgical margin and the histologic grade were the independent prognostic factors for survival. The surgical margin was an independent prognostic factor for local recurrence. An ischiopubic location of the tumor, restoration of pelvic continuity and hip joint reconstruction with total hip replacement arthroplasty were related with higher functional scores. Complications occurred in 50% of the patients and the complications varied according to the tumor location with infection being the most common complication. CONCLUSIONS Achieving an adequate surgical margin is necessary for improving the oncological outcome of pelvic sarcomas. Restoration of the pelvic continuity and the hip joint improves the functional outcome. However, complications are common and so careful selection of the reconstruction method is needed.

Abstract
INTRODUCTION Chondrosarcoma (CS) is a primary malignant bone tumor with cartilaginous differentiation. The only available treatment is carcinological surgical resection since the usual adjuvant treatments are ineffective. The pelvic location creates specific technical difficulties both for exeresis and reconstruction. Our objective was to evaluate the carcinological and functional outcomes of inter-ilioabdominal amputation and conservative surgery. MATERIALS AND METHODS We retrospectively studied 59 cases of pelvis chondrosarcoma managed in our department between 1968 and 2003. Demographic, anatomopathological, surgical and survival data were analyzed. Survival was estimated by the Kaplan-Meier curves and the cumulative incidence method. Multivariate analysis was used to identify all possible independent prognostic variables. RESULTS There were 33 men and 26 women, with an average age of 48 years. The average follow-up duration was 94 months. Eleven patients had a grade 1 chondrosarcoma, 36 a grade 2 chondrosarcoma, five were grade 3, and seven were dedifferentiated chondrosarcoma. Eleven patients underwent an inter-ilioabdominal disarticulation, and 48 had a more conservative surgery. Resection margins proved healthy in 46 patients (78%). Eighteen patients (31%) had a local recurrence, and 12 (20%) had metastases. At last follow-up, 30 patients (51%) were still alive without any sign of recurrence. Twenty-three patients (39%) died from the disease. Multivariate analysis showed that margin invasion was associated with a definitely increased local recurrence rate. A high tumoral grade was correlated with a greater risk of metastases occurrence. These two last factors (margin status and tumor grade) as well as acetabulum involvement were correlated with a reduced survival rate. Function was better among patients treated by conservative surgery, and among them, even better when the peri-acetabular area remained intact. Our study confirmed that resection margins quality is a major prognostic factor both for local control and for survival. On the other hand, local recurrence is an adverse survival prognosis factor and is itself correlated with resection margins quality. Peri-acetabular chondrosarcoma location (in zone 2) appears to be a poor oncological prognosis factor since, in this location, obtaining healthy margins appears particularly difficult. Compared to resection, inter-ilioabdominal amputation did not prove its superiority concerning resection margins quality or survival. However, resection guaranteed a better functional outcome. CONCLUSION Chondrosarcoma of the pelvic girdle remains of worse prognosis than peripheral bones chondrosarcoma since the critical prognosis factor is the resection margins quality. This location, and especially the peri-acetabular zone, poses difficult specific technical problems when conservative surgery is selected. Various imaging techniques should help better envision tumor resection extent. Inter-ilioabdominal amputation should only be resorted to in non-metastatic patients, when the tumor does not seem to be removable with sufficient healthy margins guarantee, or when local conditions make it impossible to hope for a good quality reconstruction.

Abstract
UNLABELLED Internal hemipelvectomy is performed for pelvic sarcomas when the tumor can be safely resected without sacrificing the entire extremity. Wide exposure and awareness of major neurovascular structures are crucial to the success of this surgery. Various modifications on the standard utilitarian approach have been used to best achieve these goals. We reviewed our experience using the T-incision technique for 30 pelvic sarcoma resections. The minimum followup was 3.6 months (mean, 55 months; range, 3.6-185.4 months). Postoperative complications included minor complications (requiring no surgery or a simple incision and drainage with primary closure) in 27% of patients and major complications (involving a deep infection or more extensive surgical treatment) in 17%. Ninety-two percent of wound complications healed uneventfully with antibiotics and incision and drainage. The 2-, 5-, and 10-year patient survival rates were 67%, 59%, and 53%. The 2-, 5-, and 10-year disease-free survival rates were 68%, 42%, and 42%. The mean Musculoskeletal Tumor Society and Toronto Extremity Salvage Scores were 69% and 86%, respectively. We believe the T-incision technique for internal hemipelvectomy is an effective surgical approach for pelvic sarcomas when limb salvage is possible. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Surgical strategies for the primary tumor for patients with extremity and pelvis osteosarcoma have evolved from the ablative to limb-sparing approaches over the past three decades. Favorable oncologic and functional outcomes with contemporary tissue-conserving techniques consistently observed in skeletally mature patients have prompted the application of similar approaches to a growing number of eligible skeletally immature patients. In response to emerging long-term outcome data, current strategies have focused principally on refining the nature and scope of surgical resection to preserve uninvolved tissues, and on the adoption of novel biological and nonbiological skeletal and soft-tissue reconstruction methods to optimize function. We focus on these clinical issues and discuss current efforts to advance the surgical management of the primary tumor and address the limitations of the definitive treatment of the primary tumor, including locally recurrent disease and complications of skeletal reconstructions.

Abstract
UNLABELLED Reconstruction after periacetabular resection is a challenge. We asked whether the use of pasteurized autologous grafts would provide satisfactory results regarding patient survival, local recurrence, and metastasis, and graft union and functional outcome. We retrospectively reviewed 11 patients having such grafts with a minimum followup of 12 months (mean, 40 months; range, 12-116 months). All patients underwent periacetabular (Type II) resection of malignant periacetabular tumors. The resected bone was treated in saline at 65 degrees C for 30 minutes and reimplanted into the host bone with internal fixation. Total hip arthroplasty was performed in all patients. Local recurrence occurred in two of nine patients with primary sarcoma. Ten grafts survived at the last followup. Union of the resected bone with the host bone was achieved in eight of the 11 patients at an average of 12 months. The overall functional rating was 61% according to the Musculoskeletal Tumor Society System, with better results in the patients with primary tumors. Graft fracture (one patient) and infection (one patient) were the major complications. Our data suggest the use of pasteurization may be a reasonable option for reconstruction after resection of malignant periacetabular tumors. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Survival rates of children with pelvic sarcoma have demonstrated unprecedented improvement during the past few decades, with a corresponding increase in the number of limb-sparing surgical procedures being performed. This increase may be attributed to earlier detection with advanced imaging techniques, the availability of a wider armamentarium of surgical techniques of reconstruction and limb salvage, and advances achieved in neoadjuvant chemotherapy and radiation therapy. Undertaking reconstruction after resection of pelvic sarcoma while preserving function of the hip and limb can be extremely challenging; this is especially true in children, who invite concern regarding growth potential and limb-length discrepancy. Decisions for surgery and reconstruction are individualized based on tumor type, size, and location as well as the probability of achieving a wide resection with negative margins and acceptable morbidity.

Abstract
Intralesional excision of intraosseous grade 1 periacetabular chondrosarcoma may seem an attractive alternative to the current recommendation of joint-sacrificing, en bloc resection. We report eight patients who initially underwent this treatment to identify if local tumor control can be achieved consistently. All patients had a percutaneous biopsy that was interpreted as grade 1 chondrosarcoma. The final histology after curettage indicated Grade 1 chondrosarcoma in five patients, Grade 2 in two, and dedifferentiated chondrosarcoma in one. Three of the five patients with true grade 1 chondrosarcoma have been free of disease at a median followup of 108 months. The other two patients with grade 1 chondrosarcoma on the curettage specimen recurred as higher-grade tumors. Three patients died of high-grade chondrosarcoma at a median of 23 months (range 17-72 months). Overall, the majority of patients in this cohort had either a misdiagnosis or recurrence of higher-grade disease. Based on these observations, in the absence of a predictable method to identify the true intraosseous grade 1 chondrosarcomas of the pelvis, curettage must be undertaken with the understanding that a percutaneous biopsy may misrepresent the histologic grade and that curettage may result in a higher risk of recurrence.
