Resumo Objetivo Avaliar o potencial melhor resultado funcional e controle álgico no tratamento de fraturas patológicas e fixações profiláticas tratadas com haste intramedular associada ao polimetilmetacrilato (PMMA) em comparação com o uso de haste intramedular em lesões tumorais em ossos longos. Métodos De janeiro de 2012 a setembro de 2017, 38 pacientes com 42 lesões patológicas (fraturas ou iminência segundo os critérios de Mirels) foram tratados cirurgicamente. Dezesseis pacientes submetidos a fixação com haste intramedular bloqueada foram alocados ao grupo controle e 22 pacientes com lesões patológicas foram alocados para tratamento com haste intramedular associada ao PMMA. No pós-operatório, foi realizada a submissão dos pacientes ao escore da Musculoskeletal Tumor Society (MSTS, na sigla em inglês) e à avaliação radiográfica do tratamento realizado, assim como à avaliação de intercorrências e complicações relacionadas ao tratamento. Resultados A avaliação através do questionário MSTS demonstrou melhor resultado funcional do grupo associado com PMMA quando comparado com o grupo controle, o qual obteve uma pontuação média de 16,375 em um máximo de 30 pontos (54,6%), enquanto o grupo em estudo com associação do PMMA obteve uma média de 22,36 pontos (74,5%). O procedimento mostrou-se seguro, taxas de complicações e gravidade semelhantes e sem diferença estatística quando comparado com o tratamento padrão. Conclusão A estabilização de lesões tumorais com fixação associada ao PMMA demonstrou reabilitação precoce e melhora na qualidade de vida, permitindo rápida recuperação funcional. A utilização do PMMA apresenta vantagens como diminuição do sangramento e da necrose tumoral e maior estabilidade mecânica.

Background and Objectives. Wide surgical resection is a relevant factor for local control in sarcomas. Plastic surgery is mandatory in demanding reconstructions. We analyzed patients treated by a multidisciplinary team to evaluate indications and surgical approaches, complications and therapeutic/functional outcomes. Methods. We analyzed 161 patients (86 males (53%), mean age 56 years) from 2006 to 2017. Patients were treated for their primary tumor (120, 75.5%) or after unplanned excision/recurrence (41, 25.5%). Sites included lower limbs (36.6%), upper limbs (19.2%), head/neck (21.1%), trunk (14.9%) and pelvis (8.1%). Orthoplasty has been considered for flaps (54), skin grafts (42), wide excisions (40) and other procedures (25). Results. At a mean follow-up of 5.3 years (range 2–10.5), patients continuously showed no evidence of disease (NED) in 130 cases (80.7%), were alive with disease (AWD) in 10 cases (6.2%) and were dead with disease (DWD) in 21 cases (13.0%). Overall, 62 patients (38.5%) developed a complication (56 minor (90.3%) and 6 major (9.7%)). Flap loss occurred in 5/48 patients (10.4%). The mean Musculoskeletal Tumor Society (MSTS) and Toronto Extremity Salvage Score (TESS) was 74.8 ± 14 and 79.1 ± 13, respectively. Conclusions. Orthoplasty is a combined approach effective in management of sarcoma patients, maximizing adequate surgical resection, limb salvaging and functional recovery. One-stage reconstructions are technically feasible and are not associated with increased risk of complications.

ResumoOs sarcomas ósseos e das partes moles consistem em grupo heterogêneo de neoplasias malignas de origem mesenquimal que podem ocorrer em qualquer faixa etária. O estadiamento preciso destas lesões determina as melhores estratégias terapêuticas e estimativas de prognóstico. Dois sistemas de estadiamento são os mais frequentemente empregados no manejo destas neoplasias: o sistema proposto pelo grupo da Universidade da Flórida, liderado pelo Dr. William F. Enneking (1980), adotado pela Musculoskeletal Tumor Society (MSTS) e o sistema desenvolvido pela American Joint Committee on Cancer (AJCC) (1977) que se encontra em sua 8a edição (2017). O presente artigo busca atualizar o leitor a respeito do estadiamento dos sarcomas ósseos e das partes moles que acometem o sistema musculoesquelético.

In orthopedic oncology, revisional surgery due to mechanical failure or local recurrence is not uncommon following limb salvage surgery using an endoprosthesis. However, due to the lack of clinical experience in limb salvage surgery using 3D-printed custom-made implants, there have been no reports of revision limb salvage surgery using a 3D-printed implant. Herein, we present two cases of representative revision limb salvage surgeries that utilized another 3D-printed custom-made implant while retaining the previous 3D-printed custom-made implant. A 3D-printed connector implant was used to connect the previous 3D-printed implant to the proximal ulna of a 40-year-old man and to the femur of a 69-year-old woman. The connector bodies for the two junctions of the previous implant and the remaining host bone were designed for the most functional position or angle by twisting or tilting. Using the previous 3D-printed implant as a taper, the 3D-printed connector was used to encase the outside of the previous implant. The gap between the previous implant and the new one was subsequently filled with bone cement. For both the upper and lower extremities, the 3D-printed connector showed stable reconstruction and excellent functional outcomes (Musculoskeletal Tumor Society scores of 87% and 100%, respectively) in the short-term follow-up. To retain the previous 3D-printed implant during revision limb salvage surgery, an additional 3D-printed implant may be a feasible surgical option.

Recently, custom-made 3D-printed prostheses have been introduced for limb salvage surgery in adult patients, but their use has not been described in pediatric patients. A series of 11 pediatric patients (mean age 10.8 years; range 2–13) with skeletal tumors treated with custom-made implants for the reconstruction of bony defects is described. Patients were followed up every 3 months. Functional results were evaluated by the Musculoskeletal Tumor Society Score (MSTS) for upper and lower limbs. The mean follow-up was 25.7 months (range 14–44). Three patients died after a mean of 19.3 months postoperatively—two because of disease progression and the other from a previous malignancy. Three patients experienced complications related to soft tissues. One patient required device removal, debridement, and antibiotic pearls for postoperative infection. Partial osseointegration between grafts and host bone was observed within a mean of 4 months. At the final follow-up, mean MSTS score was 75%. 3D prostheses may yield biological advantages due to possible integration with the host bone and also through the use of vascularized flaps. Further research is warranted.

Background: Juxta articular giant cell tumors around the knee constitute 50-60% of the total cases reported. If the disease is detected at an advanced stage, reconstruction of the joint after tumor excision poses problems and has poor functional outcome. The aim of the study was to determine the functional outcome after resection of juxta-articular giant cell tumors around the knee and its reconstruction with mega prosthetic arthroplasty will be analyzed.Methods: Between January 2017 and March 2021, 14 patients in the age group of 28-48 years (mean=42.85 years) with Campanacci stage three giant cell tumors around the knee were studied (12-distal femur patients, 2-proximal tibia). Patients underwent tumor excision and reconstruction with modular megaprosthesis. They were evaluated post-operatively using the Revised Musculoskeletal Tumor Society Score (MSTS) for lower limb.  Results: All the patients were followed up for 12-44 months (mean=29.5 months), the average knee flexion at 6 months being 116.4 degrees. The mean MSTS at 6, 12, 18 and 24 months are 19.45, 23.23, 26.61 and 28.77 respectively. Complications observed were infection and tumor recurrence.  Conclusions: In advanced cases where tumor excision leaves large bone segment loss, reconstruction with megaprosthesis can give desirable functional outcome.

Abstract Background: Surgical resection and reconstruction for low grade bone sarcoma in the metaphysis of the long bone remains challenging. We hypothesize that 3D printing osteotomy guide plate could assist to accurately resect the tumor lesion and save the joint function without higher recurrence rate. Methods: From January 2017 to August 2019, ten patients with low-grade malignant bone tumor in metaphysis of the limbs were treated with hemicortical resection using 3D printing guide plate and biological reconstruction. Results: Four patients were paracorticular osteosarcoma, five cases had highly differentiated chondrosarcoma, and one case was a chondromyxoid fibroma. Two of the cases involved the proximal humerus, while eight cases involved the distal femur. There was neither post-operation infection, internal fixation loosening, nor fracture occurrence in any of the patients. The Musculoskeletal Tumor Society score averaged at 27.1, while the International Society of Limb Salvage imaging score examination averaged 87.8%. Conclusions: Here, we demonstrate that the 3D printing osteotomy guide plate assisted hemicortical bone resection is a beneficial strategy to effectively resect the primary low-grade malignant bone tumors in the metaphysis of long bone and restore excellent joint function.

Background: Giant Cell Tumor of the bone (GCTB) has got variable outcome after the different methods of surgical treatment depending upon the site and grade of lesion and extent of tumor removal. This retrospective prospective analysis of operatively treated cases of GCTB of different sites aimed to highlight the clinical outcome. Methods: This was a prospective observational study of 18 cases of GCTB; proximal tibia (n=6), distal femur (n=5), distal radius (n=4), proximal femur (n=1), proximal fibula (n=1) and anterior arc of first rib (n=1) treated with different operative management with mean follow up of 53.61 months. Functional outcome with Musculoskeletal Tumor Society Score (MSTS), recurrence and complications were analyzed with at least 24 months of follow up. Results: There were 10 females and 8 males with average age at presentation 27.3 years (range 15-38). Average duration of symptom was 4.72 months. 2 were cases of recurrence previously op­erated and 16 were de novo cases. Mean MSTS was 84.27% with good to excellent result in 88%. There were no non-union, graft failure, metastasis, prosthetic failure or wound infection till at least 24 months of follow up in any of the cases. Conclusions: Extended curettage or reconstruction with auto graft in grade I and II tumor or en­doprosthesis in higher grade or recurrence of GCTB can give good to excellent functional result in majority of the cases.

AbstractFor patients with tumors of the distal femur, options for limb salvage include tumor resection followed by reconstruction. While reconstruction commonly involves a distal femoral replacement, careful selection of patients with tumor involvement limited to a single condyle may be candidates for reconstruction with distal femur hemiarthroplasty. In these procedures, resection spares considerably more native anatomy. Three consecutive patients who underwent resection and reconstruction at the distal femur with custom unicondylar hemiarthroplasty are presented in this case series at a mean follow-up of 45 months (range, 26–78). In two cases, prostheses were utilized as a secondary procedure after failure of initial reconstruction. In one case, the custom prosthesis was utilized as the primary method of reconstruction. Mean Musculoskeletal Tumor Society disease-specific scores were 26.7 (range, 25–28). All patients achieved a return to full weight bearing, activities of daily living, and functional range of motion. In appropriately selected patients with tumors of the distal femur, reconstruction with custom unicondylar hemiarthroplasty provides benefits including optimal function postoperatively via preservation of tumor-free bone and ligamentous structures. Additionally, maintenance of greater bone stock may confer benefits to patients with pathology at a high likelihood for recurrence and need for subsequent procedures.
