Abstract
INTRODUCTION Extra-articular hip resection may be necessary in cases of malignant tumour of the pelvic bone or of the proximal femur invading the hip joint. When the tumour is in the proximal femur, it is possible to resect the acetabulum en bloc by performing a periacetabular osteotomy, but this creates a discontinuity in the pelvic ring with difficult reconstruction and diminished function. Several techniques described recently seek to be as sparing as possible on the pelvic bone by preserving the posterior column or both columns in order to facilitate reconstruction and improve function. However, these still require complex reconstructions and can necessitate intra-pelvic dissection. TECHNIQUE We describe here an extra-articular hip resection technique for tumours of the proximal femur invading the joint, with maintenance of pelvic continuity by preserving both columns and the quadrilateral plate of the acetabulum, without intra-pelvic dissection, that can be performed on patients in whom the medial wall of the acetabulum is thick enough. Our preliminary assessments have included studies on dry bone and imaging analyses. The technique was first tested on a single cadaver pelvis (encompassing 2 hips) and subsequently performed on a patient with a pathological fracture of the femoral neck due to osteosarcoma secondary to Paget's disease. CONCLUSIONS Further clinical applications are essential to evaluate the overall effectiveness, safety and impact on patient functionality of this experimental technique.

Front Bioeng Biotechnol 2024; 12:1349819. [PMID: 38333079 PMCID: PMC10850231 DOI: 10.3389/fbioe.2024.1349819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 01/08/2024] [Indexed: 02/10/2024] Open
Abstract
Objective: Considering the advantages and widespread presence of 3D-printing technology in surgical treatments, 3D-printed porous structure prostheses have been applied in a wide range of the treatments of bone tumor. In this research, we aimed to assess the application values of the 3D-printed custom prostheses with ultra-short stems for restoring bone defects and maintaining arthrosis in malignant bone tumors of lower extremities in children. Methods: Seven cases of pediatric patients were included in this study. In all cases, the prostheses were porous titanium alloy with ultra-short stems. MSTS 93 (Musculoskeletal Tumor Society) scores were recorded for the functional recovery of the limbs. VAS (Visual analogue scale) scores were utilized to assess the degree of painfulness for the patients. X-ray and MRI (magnetic resonance imaging) were applied to evaluate the bone integration, prostheses aseptic loosening, prostheses fracture, wound healing, and tumor recurrence during follow-up. Results: During follow-up, none of the patients developed any postoperative complications, including prostheses aseptic loosening, prostheses fracture, or tumor recurrence. Radiological examinations during the follow-up showed that prostheses implanted into the residual bone were stably fitted and bone defects were effectively reconstructed. The MSTS 93 scores were 24.9 ± 2.9 (20-28). VAS scores were decreased to 5.8 ± 1.2 (4.0-7.0). No statistically significant differences in leg length discrepancy were observed at the time of the last follow-up. Conclusion: 3D-printing technology can be effectively applied throughout the entire surgical treatment procedures of malignant bone tumors, offering stable foundations for the initial stability of 3D-printed prostheses with ultra-short stems through preoperative design, intraoperative precision operation, and personalized prosthesis matching. With meticulous postoperative follow-up, close monitoring of postoperative complications was ensured. These favorable outcomes indicate that the utilization of 3D-printed custom prostheses with ultra-short stems is a viable alternative for reconstructing bone defects. However, further investigation is warranted to determine the long-term effectiveness of the 3D-printing technique.

Abstract
OBJECTIVE This study aimed to identify clinical measures that have been used to evaluate function, health related quality of life (HRQoL), and/or satisfaction in children who use lower limb prostheses (LLP). The data reported on psychometric properties for children who use LLP were collected for each measure. METHODS First, PubMed, CINAHL, and Web of Science databases were searched using broad search terms to identify standardized outcome measures of function, HRQoL, and/or satisfaction with treatment used in pediatric LLP research published in 2001 or after. For each of the eligible measures found, a second search was performed to identify psychometric properties (e.g., validity, reliability) assessed with children who use LLP. RESULTS Forty-four standardized outcome measures were identified from 41 pediatric LLP research articles. Five measures (i.e., Gait Outcomes Assessment for Lower Limb Differences, Functional Mobility Assessment, Child Amputee Prosthetics Project- Prosthesis Satisfaction Inventory, Child Amputee Prosthetics Project- Functional Scale Index, and Lower Limb Function Questionnaire) had data on psychometric properties for children who use LLP. CONCLUSIONS Few studies report psychometric data for assessing the overall HRQoL, function, and/or satisfaction for children who use LLP. Further research is needed to validate or create new outcome measures that assess the HRQoL, satisfaction, and/or function of children who use LLP.

Abstract
To evaluate the effectiveness of limb-salvage treatment for osteosarcoma in adolescent patients, a comprehensive search on PubMed, Embase and Cochrane Library was conducted. Studies with a clear diagnosis of osteosarcoma were included and duplicate publications, studies without full text or incomplete information, those with an inability to extract data, divergent definitions of exposure, animal experiments, reviews, and systematic reviews were excluded. The data were analyzed using STATA 15.1. The findings of the present study revealed that overall survival (OS) and progression-free survival (PFS) of patients with osteosarcoma in the limb-salvage treatment group were significantly longer than those in the amputation treatment group [hazard ratio (HR)=0.71; 95% confidence interval (CI): 0.63-0.80; P=0.000 vs. HR=0.60; 95% CI: 0.48-0.76; P=0.000]. Additionally, the five-year OS rate for patients in the limb-salvage treatment group was higher than that in the amputation group [odds ratio (OR)=4.48; 95% CI: 2.74-7.31; P=0.000]. However, the local recurrence rate was notably higher in the limb-salvage treatment group compared with the amputation treatment group (OR=2.68; 95% CI: 1.50-4.77; P=0.001). Furthermore, the results indicated no significant difference in distant metastasis rates between the limb-salvage treatment group and the amputation treatment group (OR=0.32; 95% CI: 0.10-1.06; P=0.062). In conclusion, the present meta-analysis underscores the potential of limb-salvage therapy for adolescent patients with osteosarcoma. The OS and PFS of patients undergoing limb-salvage surgery are longer than those of amputation, with a higher five-year OS rate and a similar rate of distant metastasis. However, the local recurrence rate of limb-salvage surgery is significantly higher than that of amputation.

Abstract
BACKGROUND Bone tumors remain a formidable challenge for orthopedic surgeons. In developing countries, the challenge is exacerbated by limited diagnostic, therapeutic, and management facilities and ignorance. Patients with upper and lower-extremity muscle and skeletal tumors are candidates for amputation or surgical rescue of the limbs. Traditionally, limb rescue surgery by neo-adjuvant chemotherapy is the preferred surgery method for localized carcinoma. Amputations are usually reserved for patients with increased tumor size. The purpose of this study is to investigate health-related quality of life (HRQOL) and physical disability, focusing on surgical care, gender, and age, in adolescent and young adult survivors of malignant bone tumors treated surgically. METHODS This cross-sectional study consists of 38 long-term survivors who underwent amputation or limb-salvage surgery at King George's Medical University, Lucknow, from 2019 to 2022. After obtaining ethical clearance and informed consent, 38 patients which included 26 patients treated with limb salvage in Group A and 12 patients treated with amputation in Group B were included in the study. The SF-36 and HUI3 scores were used to assess the functional outcome and health-related QoL of these patients. RESULTS After minimal six months of interventions, we have found a significant improvement in all the following factors: physical functioning (P=0.000), role limitations due to physical health (P=0.000) and emotional problems (P=0.001), energy/fatigue (P=0.000), emotional well-being (P=0.000), social functioning (P=0.000), pain (P=0.000), and general health (P=0.000). Group A showed a higher degree of significance than Group B through SF-36 (Short Form-36, patient-reported outcome), whereas HUI-3 did not show any significant outcomes (P=0.347). CONCLUSION The overall quality of life of patients with salvaged limbs appears to be higher than that of the quality of life of amputee patients in tumor survivor patients. Further analyses must be carried out to verify the results and focus on areas that have a major impact on the overall quality of life using other assessment tools. The impact of therapy on the quality of life depends on maintaining the necessary structures for functional functions, adjusting patient expectations to cancer treatments, and designing long-term rehabilitation programs to support functional functions.

Abstract
PURPOSE OF THE REPORT Several methods are used to reconstruct bony defects after malignant tumor excision. Tumor-bearing frozen autograft reconstruction is a biological procedure in which tumor-bearing bone is reused after devitalization with liquid nitrogen to kill tumor cells. The viability of frozen autografts has not been fully evaluated over time. We therefore aimed to evaluate the viability of devitalized bone grafts, using 99m Tc-MDP scintigraphy. PATIENTS AND METHODS Seventy-four patients who underwent frozen autograft reconstruction after the excision of a malignant bone tumor were enrolled. Two hundred forty-two postoperative 99m Tc-MDP scans were reviewed. For a quantitative analysis, the region of interest on the frozen bone segment and a symmetric region of interest on the contralateral normal area were manually set. The radioactive tracer uptake ratio was calculated by dividing the count density of the frozen bone segment by that of the contralateral normal area in each image. An uptake ratio of 0.9 to 1.1 was defined as a normalization of tracer uptake. RESULTS Normalization of tracer uptake was achieved in 95% to 97% of the cases by 60 months postoperatively, and earlier in the middle zone and peripheral zone in the pedicle freezing group in comparison to the free freezing group (both P = 0.03). Fracture and nonunion was associated with a low uptake ratio, whereas infection was associated with a high uptake ratio before the occurrence of the event. CONCLUSIONS The calculation of the uptake ratio using 99m Tc-MDP scans was an objective and accurate evaluation method. The period to normalization of tracer uptake in the pedicle frozen bone was significantly earlier than that in the free frozen bone. The postoperative complications can be also predicted.

Abstract
This systematic review investigated the functional outcomes and complications of reconstruction methods after talar tumor resection. A systematic search of PubMed, Embase, and the Cochrane Central Register of Controlled Trials databases identified 156 studies, of which 20 (23 patients) were ultimately included. The mean Musculoskeletal Tumor Society scores in the groups reconstructed using tibiocalcaneal fusion (n = 17), frozen autograft (n = 1), and talar prosthesis (n = 5) were 77.6 (range 66-90), 70, and 90 (range 87-93), respectively. Regarding complications, sensory deficits were observed in one patient (6%) and venous thrombosis in two patients (12%) in the tibiocalcaneal fusion group, while osteoarthritis was observed in one patient (100%) in the frozen autograft group. No complications were observed in the talar prosthesis group. Reconstruction with talar prosthesis seems preferable to conventional tibiocalcaneal fusion after talar tumor resection because it offers better function and fewer complications. However, as this systematic review included only retrospective studies with a small number of patients, its results require re-evaluation in future randomized controlled trials with larger numbers of patients.

Abstract
BACKGROUND Reconstruction after en bloc resection of the distal tibia has remained an unsettled issue despite many attempts with bone grafts or prostheses in the past. Failures of the previous methods have been attributed to inadequate mechanical strength, poor articular stability, failed osseointegration, and poor soft tissue coverage. To overcome these shortcomings, we designed and applied a 3D-printed megaprosthesis with ankle arthrodesis. METHODS A total of 13 patients underwent resection of a distal tibial tumor and reconstruction with a 3D-printed distal tibial megaprosthesis between January 2017 and November 2020. Mean age was 14.9±6.5 years. Diagnoses included 11 cases of osteosarcoma and 1 case each of low-grade phosphaturic mesenchymal tumor and rhabdomyosarcoma. Baseline characteristics, operative data, complication profiles, and oncologic, and functional outcomes were reviewed and analyzed. RESULTS All 13 cases attained a wide or marginal resection. During a mean follow-up of 26.8±10.6 months, 1 patient experienced local recurrence and distant metastasis, whereas 3 other patients only developed distant metastasis. Periprosthetic infection subsequent to paronychia occurred in 1 patient 24 months after the operation. No other complications were observed. By the last follow-up, the mean MSTS-93 score was 28.0±1.5. CONCLUSION In this relatively small cohort with short-term follow-up, reconstruction with the 3D-printed megaprosthesis with ankle arthrodesis was found to be a safe and efficacious method after resection of a distal tibial malignancy.

Abstract
Objective To evaluate the feasibility and short-term effectiveness of three-dimensional (3D) printed titanium-alloy prosthesis reconstruction after the distal tibia tumor segment resection. Methods The clinical data of 6 patients with bone defect after distal tibia tumor segment resection treated with 3D printed titanium-alloy prosthesis reconstruction and tibiotalar joint fusion between January 2020 and December 2021 were retrospectively analyzed. There were 2 males and 4 females; the age ranged from 12 to 35 years, with an average of 18.5 years. Among them, 4 cases were osteosarcoma, 1 case was Ewing sarcoma, and 1 case was giant cell tumor of bone. The Enneking staging was stage ⅡA in 3 cases, stage ⅡB in 2 cases, and stage Ⅲ in 1 case. The disease duration was 2-5 months (mean, 3.2 months). All patients received preoperative neoadjuvant therapy, and patients with osteosarcoma and Ewing sarcoma started chemotherapy at3 weeks after operation. The systemic and local tumor conditions and prosthesis conditions were evaluated regularly after operation. The Musculoskeletal Tumor Society (MSTS) score and the American Orthopaedic Foot and Ankle Society (AOFAS) score were used to evaluate the lower extremity and ankle function. Results All patients were followed up 8-26 months, with an average of 15.6 months. There was no local recurrence and distant metastasis during the follow-up. The ankle joints of 5 cases were all in 90° functional position at last follow-up, and there was no complication such as prosthesis loosening and fracture; the ankle joint fusion was stable, the local bone ingrowth was good, and the daily activities could be completed, but the ankle range of motion was limited and the ankle joint was stiff. The MSTS score ranged from 22 to 26, with an average of 24, and 3 cases were evaluated as excellent and 2 cases were good; the AOFAS score ranged from 71 to 86, with an average of 80.6, and 4 cases were evaluated as good and 1 case was fair. One patient had severe periprosthetic infection at 2 months after operation, resulting in failure of prosthesis implantation, pain in limb movement, and poor ankle function; MSTS score was 12, AOFAS score was 50, and both were evaluated as poor; distraction osteogenesis was performed after removal of prosthesis and infection control, at present, it was still in the process of distraction osteogenesis, and local osteogenesis was acceptable. Conclusion Using 3D printed titanium-alloy prosthesis and tibiotalar joint fusion to reconstruct the bone defect after distal tibia tumor segment resection has satisfactory mechanical stability and function, and is one of the effective distal tibial limb salvage methods.

Abstract
Background Although clinicians and patients with extremity bone and soft tissue (EBST) are increasingly interested in limb salvage surgery (LSS), because of the minimal damage to physical appearance and function, however, there is still a lack of large-scale population studies on whether LSS improves the prognosis of patients. Purpose The aim of this study was to compare the survival of patients with EBST sarcomas after receiving LSS and amputation. Methods To conduct the population-based study, we identified 6,717 patients with a histologically diagnosed bone sarcoma and 24,378 patients with a histologically diagnosed soft tissue sarcoma from the Surveillance, Epidemiology, and End Results database. We analyzed overall survival (OS), cancer-specific survival (CSS), and non-sarcoma survival (NSS) using the Kaplan-Meier method, log-rank test or Gray test, Cox regression model, propensity score-matched analysis, and landmark analysis. Results LSS could improve the prognosis in patients with most EBST subtypes, except for Ewing sarcomas and MPNST. However, in the subgroup without distant metastases, limb salvage increased CSS only for patients with osteosarcoma, Ewing sarcoma, and leiomyosarcoma, as well as NSS for patients with chondrosarcoma and synovial sarcoma. Landmark analysis further demonstrated that sarcoma survivors surviving <10 years could benefit from LSS but not for long-term survivors ≥10 years. Moreover, for patients with distant metastases, LSS could improve survival of osteosarcoma patients but worsen CSS among patients with MPNST. Landmark analysis further demonstrated that LSS improved survival among osteosarcomas patients with distant metastases only within 1 year after surgery. Moreover, patients receiving LSS and those receiving amputation had a high risk of dying from different non-sarcoma diseases during the postoperative follow-up. Conclusions The impact of limb salvage on the prognosis of patients depends on the pathological subtype and stage of EBST sarcomas.

Abstract
BACKGROUND Biological reconstruction after tumor resection is significant for restoration of limb integrality. However, it is unclear what risk factors influence mechanical complications of patients after extremity sarcoma resection and biological reconstruction. The objective of study was (1) to compare complications between patients receiving inactivated autograft and allograft, (2) to analyze influence of graft type, nonunion and fixation method on mechanical complications for patients after biological reconstruction. HYPOTHESIS We hypothesized allograft, nonunion and fixation method influence occurrence of mechanical complications after biological reconstruction. MATERIALS AND METHODS We retrospectively reviewed 71 patients with sarcomas at the extremity receiving biological reconstruction from January 1999 to November 2015. Eight patients were lost at last follow-up. Sixty-three patients with complete clinical data were recruited into the present study. There were 32 males and 31 females with a mean age of 20.5±14.9 years (median, 17 years; range, 2-72 years). Sixty-one cases had tumors at lower extremity and two at upper extremity. Histological diagnosis was confirmed as forty-five with osteosarcoma, thirteen with Ewing sarcoma and five with chondrosarcoma. RESULTS Forty-four patients were free of disease, sixteen died of disease and three lived with pulmonary metastasis at last follow-up. Twenty-one out of 63 patients (33.3%) had local recurrence requiring surgical treatment. Reconstruction choice (mechanical complications rates were 38.9% for allograft (14/36) versus 14.8% for inactivated autograft (4/27)) and nonunion occurrence (yes 58.8% (10/17); no 17.4% (8/46)) had the close relationship with mechanical complication in the univariate analysis. The multivariate analysis revealed fixation method (p=0.041) and nonunion (p=0.008) were prognostic factors for mechanical complication of sarcoma resection and biological reconstruction at the extremity. Fourteen of 36 patients receiving massive allograft had a second surgery due to mechanical complication compared to 4 of 27 patients with massive inactivated autograft (38.9%, 14/36 vs. 14.8%, 4/27 (p=0.05)). Time to union for diaphysis and metaphysis was not significantly different between allograft and inactivated autograft groups. DISCUSSION Patients receiving massive allograft are prone to suffer from the mechanical complications. Extramedullary plate and nonunion have the tendency of increasing occurrence of mechanical complications of biological reconstruction. LEVEL OF EVIDENCE IV; retrospective study.

Case Report: Reconstruction of Medialis Malleolus (1/4 of the Ankle Joint) After Resection of Distal Tibia Tumor With an Uncemented Three-Dimensional-Printed Prosthesis. Front Surg 2022; 9:844334. [PMID: 35402484 PMCID: PMC8987288 DOI: 10.3389/fsurg.2022.844334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Accepted: 02/22/2022] [Indexed: 11/13/2022] Open
Abstract
Introduction Few patients presented with a distal tibial tumor that only invaded a small area of bone in the medial malleolus. There have been no previous cases in which only the medial or lateral malleolus was removed and reconstruction was complete. This article describes our attempt to reconstruct the medial malleolus (1/4 of the ankle joint) after resection of a distal tibial tumor with an uncemented three-dimensional (3D)-printed prosthesis. Case Description A 39-year-old man presented with a lump in the right medial malleolus, and biopsy results suggested fibrosarcoma. To preserve the patient's normal bone and function, we only removed the medial malleolus and reconstructed the ankle joint using a personalized 3D-printed prosthesis. The patient had no complications other than necrosis of the skin flap that covered the wound. The patient recovered well after undergoing an additional skin flap transfer. Follow-up at 7 months and again at 3 years after surgery showed good ankle function and stability, with no pain or complications. Conclusion The 3D-printed partial ankle prosthesis had a good matching degree, strength, and osseointegration ability, but also had a few complications. The patient achieved satisfactory ankle function and stability. However, a longer follow-up period is needed, and more research is required to confirm the efficacy of the prosthesis.

A meta-analysis comparing efficiency of limb-salvage surgery vs amputation on patients with osteosarcoma treated with neoadjuvant chemotherapy. Int Wound J 2022; 19:1616-1624. [PMID: 35122396 PMCID: PMC9615273 DOI: 10.1111/iwj.13758] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2022] [Revised: 01/08/2022] [Accepted: 01/09/2022] [Indexed: 11/27/2022] Open
Abstract
Osteogenic sarcoma is the central malignant bone neoplasm affecting the bones of arms and legs and rarely the soft tissues outside the bones. Historically, amputation was the chief surgical technique; currently, the popular standard is limb salvage surgery (LSS), although both procedures' effect on 5‐year‐event survival, 5‐year disease‐free survival rates (DFS) and the local recurrence is uncertain. Therefore, this meta‐study aimed to establish the relationship between the effect of LSS and amputation in subjects with osteogenic carcinoma. A systematic survey till January 2021 to know the effect of LLS vs amputation with subjects treated with neoadjuvant chemotherapy was conducted. Clinical studies were identified with 9760 subjects with osteosarcoma of the extremities at the beginning of the trial; 7095 of them were managed with limb salvage surgery and 2611 with amputation. This study tried to compare the effects of LSS vs amputation in subjects with osteogenic sarcoma in the extremities. The dichotomous method in statistical analysis was used as a tool for establishing odds ratio (OR) at a confidence interval of 95% (CI) to assess the efficiency of LSS and amputees with osteosarcoma of the extremities with a fixed or random‐effect model. Although patients with osteosarcoma of the extremities managed with LSS were significantly related to a higher local recurrence rate than those treated with amputation, they were also associated with higher 5‐year overall survival (OS) than amputation. Patients showed no significant difference in a 5‐year DFS rate between LSS vs amputation. The subjects who have undergone LSS for osteosarcoma of the extremities may have a higher risk of local recurrence than amputees. However, LSS may increase 5‐year OS compared to amputees. These results depict that local recurrence of osteosarcoma does not influence survival rate. However, more studies are needed to validate this finding.

Abstract
Open tibial plafond fracture with massive bone loss presents a challenge for orthopedic surgeons. Particularly unusual is extrusion of an osteoarticular segment of the distal tibia. Here we present the case of such a patient, who was treated using osteochondral allograft (OCA) and fusion procedures. The patients can regain independent walking without pain within 6 months, indicating that OCA may be a sensible option for the treatment of open tibial plafond fracture with extrusion of the osteoarticular distal tibia in cases in which the surrounding soft tissue is intact but bone reimplantation is not possible due to severe damage and contamination.

Abstract
Implant failure is the most common reason for revision of growing prostheses. Maximum prosthesis growth with a residual LLD is the most common mode of failure. Functional outcomes are good, but 1/ 5 patients have a persistent LLD over 2 cm.
Background Non-invasive expandable endoprostheses (NIEPR) utilize an external electromagnetic field to drive an innate mechanical gearbox. This lengthens the extremity following oncological resections in children with a predicted limb length discrepancy (LLD), facilitating limb-salvage. This review was conducted to assess NIEPR implant survival rates and identify modes of implant failure unique to these prostheses. Methods Medline, EMBASE and the Cochrane Library databases were searched for all manuscripts evaluating implant survival of NIEPRs implanted into skeletally immature patients following resection of extremity sarcomas. Minimum follow-up of 12 months or implant failure was required for inclusion. Failures were classified using the latest ISOLS classification and exact implant-specific failure modality was also identified. Results 19 studies met inclusion criteria. Mean age was 10.0 years (7.7 – 11.4 years). The most common locations for NIEPR implantation were the distal femur (343, 76.7%) and proximal tibia (53, 119%). Mean follow-up was 65.3 months (19.4 – 163 months). The overall implant revision rate was 46.2% (0 – 100%); implant specific revisions included maximal prosthesis lengthening with persistent LLD (10.4%), failed extension mechanism (6.1%), implant fracture (7.7%), hinge fracture (1.4%) and bushing wear (0.9%). Persistent clinically significant (>20 mm) LLD at final follow-up was present in 19.2% (0 – 50%) of patients. The mean MSTS score was 85.1% (66.7–96.3%) at final follow-up. Conclusion Implant-related failures are the most common reason for NIEPR revision. Implant reliability appears to be improved with current designs. A sub-classification to the current classification system based on implant-specific failures for NIEPRs is proposed.

Abstract
Simple Summary Sarcomas are malignant tumors of soft tissues or bone. While limb salvage surgery (LSS) is the standard treatment, amputation is an option especially in local recurrence (LR) or complications after LSS. Two groups with primary amputations (n = 120) or secondary amputations after failed LSS due to LR or complications (n = 29) were compared. Five-year LR-free survival was 84% and 17 (16%) patients developed LR, of which 16 were in group I and only one in group II. Overall survival (OS) at five years was 44%, and the rate was identical in both groups. In those group II patients who had a secondary amputation after LSS due to contaminated margins or LR (n = 12) five-year OS was 33% compared to 48% in patients with complications (n = 17). This study indicates the worse oncological outcomes with respect to OS of sarcoma patients needing an amputation as compared to LSS. Patients with primary amputation or those who had a secondary amputation after failed LSS for whatever reason showed the same results. Abstract Background: Sarcomas are rare, malignant tumors of soft tissues or bone. Limb salvage surgery (LSS) is the standard treatment, but amputation is still an option, especially in local recurrence or complications after LSS. Methods: We retrospectively reviewed indications and oncological outcomes in patients who underwent an amputation. Two groups with either primary amputations (n = 120) or with secondary amputations after failed LSS with local recurrence or complications (n = 29) were compared with the main end points of LRFS and OS. Results: Five-year LRFS was 84% with 17 (16%) patients developing local recurrence, of which 16 (13%) occurred in group I. Forty-two (28%) patients developed metastatic disease and overall survival at five years was 44%. Overall survival (OS) was the same in both groups. In those group II patients who had a secondary amputation due to LR or insufficient margins after LSS (n = 12) the five-year OS was 33% compared to 48% in patients with amputation due to complications (n = 17) (n.s.). Conclusions: This study indicates the worse oncological outcomes with respect to OS of sarcoma patients requiring an amputation as compared to LSS. Patients with primary amputation or those who had a secondary amputation after failed LSS for whatever reason showed the same oncological results.

Abstract
First to evaluate PROMIS for patients undergoing radiotherapy and surgery for sarcoma. Patients exhibited meaningful change in PROMIS scores throughout the treatment. Analyses show PROMIS scores were similar between pre- and post-operative radiotherapy. Wound complications were associated with increases in anxiety and decreases in function. These data should be considered when selecting ideal therapy.
Introduction Few recent studies have examined patient reported outcomes (PROs) during pre- or post-operative radiation therapy (RT) for soft tissue sarcoma (STS), and none have used PROMIS. This study aims to examine PROMIS scores across peri-operative time points for patients receiving pre- or post-operative RT. Methods Anxiety, depression, pain interference, and physical function PROMIS domains were collected at the pre-operative (1), immediate post-operative (2), and post-treatment completion (3) timepoints for patients undergoing surgery and either pre-operative or post-operative RT. Median scores were compared between groups using the Kruskal-Wallis test. The reliable change index was used to determine minimum important change in PROMIS scores and to compare scores between timepoints. Results 95 patients were included (19 pre-operative, 76 post-operative). Both groups had significant decreases in function during treatment. Patients with wound complications were more likely to have significant increases in anxiety (36.4% vs. 8.3%; p = 0.020) and decreases in physical function (57.1% vs. 16.2%; p = 0.011) independent of RT timing. Conclusions This study demonstrates minimum significant change thresholds to detect PROMIS changes in STS patients undergoing pre- and post-operative radiotherapy. As expected, more patients with pre-operative RT than post-operative RT had wound complications (p = 0.06), but patients with complications in both groups had worse anxiety and function at the completion of treatment compared with those that did not. The association of wound complications with worse anxiety and physical function at completion of treatment should be considered when making individualized treatment recommendations regarding the timing of RT.

Abstract
Introduction Adamantinoma is a rare low-grade malignant tumor in young adults. Recent advances in molecular techniques have shown different variants with discordance between genotype and phenotype. This poses a challenge in diagnosis and management. Ewing’s-like adamantinoma is one such variant. The appropriate treatment protocol for this dedifferentiated tumor remains to be established. Here, we present a rare case of Ewing’s-like Adamantinoma treated with limb salvage surgery using three step Ilizarov technique with good results. Case Report A 38-year-old lady presented at our OPD complaining of recent onset pain and gradual increase in size over a long standing swelling in the right lower tibia. Radiologically was diagnosed as Ewing’s but was not responsive to chemotherapy. A Tru-Cut biopsy showed histological picture of dedifferentiated adamantinoma. Immunohistochemistry showed CD99 positivity. FISH revealed (11;22) translocation confirming Ewing’s-like adamantinoma. She was managed with wide excision followed by staged Ilizarov distraction-osteogenesis and bone transport to correct the 13 cm discrepancy in bone length. There have been no signs of recurrence on post-resection follow-up of 2 years. Patient attained full range of knee and ankle movements. Conclusion The controversy as to what constitutes the difference between adamantinoma-like Ewing’s and Ewing’s-like adamantinoma persists despite technological advances. The appropriate treatment protocol remains to be established. Ilizarov three step techniques provide a feasible alternative to amputation while circumventing the difficulties of large bone reconstruction in the distal tibia.

Abstract
The incidence of primary malignant bone tumors is low, and clinical cognition is insufficient. The establishment of diagnostic criteria is of great significance for prognosis of tumors. National Comprehensive Cancer Network (NCCN) regularly publishes "Clinical Practice Guidelines for Bone Tumors" to summarize the latest treatment progress of bone tumors. In the latest version of the guidelines released in November 2020, surgery is the main treatment for chondrosarcoma, chordoma, and giant cell tumor of bone, which can be combined with radiotherapy or targeted therapy. Ewing's sarcoma and osteosarcoma are treated by surgery combined with chemotherapy. Immunotherapy can be used to treat high-grade undifferentiated pleomorphic sarcoma. For recurrent tumors, surgery combined with radiotherapy, chemotherapy, and/or targeted therapy can be used for control. The guidelines provide a reference for the standard treatment of bone tumors.

Abstract
Age affects the clinical outcomes of cancer treatment, including those for bone sarcoma. Successful reconstruction using frozen autograft after excision of bone sarcoma has been reported; however, little is known about the clinical outcomes of frozen autograft reconstruction according to age. The purpose was to evaluate the clinical outcomes of the frozen autograft reconstruction focusing on skeletally mature adolescents and young adults (AYAs) that was 15 to 39 years of age. A total of 37 AYA patients with primary bone sarcoma on the appendicular skeleton were enrolled in this study. The mean follow-up period was 89 months. The graft survival (GS), overall survival (OS), recurrence-free survival (RFS), complications and the function were retrospectively evaluated using medical records. The 10-year GS, OS, and RFS rates were 76%, 84%, and 79%, respectively. Bone union was achieved with a rate of 94% within 1 year after surgery, and nonunion (n = 1) and fracture (n = 2) were infrequently observed. Graft removal was performed in 7 cases, and the most common reason for the removal was infection (n = 5). The Musculoskeletal Tumor Society score was excellent in 23 cases of the available 29 cases. Frozen autograft reconstruction for AYAs showed excellent clinical outcomes, although the long-term follow-up is required.

INTERNATIONAL ORTHOPAEDICS 2021; 45:2973-2981. [PMID: 34414485 DOI: 10.1007/s00264-021-05161-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Accepted: 07/17/2021] [Indexed: 11/24/2022]
Abstract
PURPOSE This retrospective, single-centre study compares the clinical and radiographic outcomes of limb reconstruction using recycled autografts to that using allografts. METHODS Patients with histopathologically verified high-grade osteosarcoma treated with wide bone resection and limb reconstruction using allografts or recycled autografts from January 1998 through December 2012 were retrospectively screened for enrolment eligibility. The final study cohort included 255 patients (allograft, 91; recycled autograft, 164). Data regarding post-operative complications, salvage treatment, and graft survival were collected. A modified International Society of Limb Salvage classification system was used to evaluate the radiographic findings. RESULTS The time to graft-host union did not differ significantly between the two graft types. Patients receiving recycled autografts had fewer complications compared than did those receiving allografts (recycled autografts vs. allograft: structural failure, 4.3 vs. 13.2%; late infection, 2.4 vs. 7.7%; all p < 0.05). Complications occurred most frequently during the first three years after surgery, and the majority were manageable. The five year limb survival rate did not differ significantly between the two graft types (91.3 vs. 94.0%; p = 0.752). No local oncological recurrence was observed within the recycled autografts. CONCLUSION Recycled autografts and allografts are feasible options for biological limb reconstructions in terms of complications and graft survival after wide resection of osteosarcoma.

Abstract
PURPOSE The main challenge in reconstruction after malignant bone tumour resection in young children remains how and when growth-plates can be preserved and which options remain if impossible. METHODS We describe different strategies to assure best possible long-term function for young children undergoing resection of malignant bone tumours. RESULTS Different resources are available to treat children with malignant bones tumours: a) preoperative planning simulates scenarios for tumour resection and limb reconstruction, facilitating decision-making for surgical and reconstructive techniques in individual patients; b) allograft reconstruction offers bone-stock preservation for future needs. Most allografts are intact at long-term follow-up, but limb-length inequalities and corrective/revision surgery are common in young patients; c) free vascularized fibula can be used as stand-alone reconstruction, vascularized augmentation of structural allograft or devitalized autograft. Longitudinal growth and joint remodelling potential can be preserved, if transferred with vascularized proximal physis; d) epiphysiolysis before resection with continuous physeal distraction provides safe resection margins and maintains growth-plate and epiphysis; e) 3D printing may facilitate joint salvage by reconstruction with patient-specific instruments. Very short stems can be created for fixation in (epi-)metaphysis, preserving native joints; f) growing endoprosthesis can provide for remaining growth after resection of epi-metaphyseal tumours. At ten-year follow-up, limb survival was 89%, but multiple surgeries are often required; g) rotationplasty and amputation should be considered if limb salvage is impossible and/or would result in decreased function and quality of life. CONCLUSION Several biological and technological reconstruction options must be merged and used to yield best outcomes when treating young children with malignant bone tumours.

Abstract
Introduction Reconstruction of a large bone defect of the distal tibia after limb salvage surgery is difficult. The options include custom-made ankle endoprosthetic replacement, arthrodesis, and biological or metallic intercalary reconstructions. This report introduces a technique that provides the patient with a long-lasting biological reconstruction while preserving the native ankle. Presentation of case We present the case of a 47-year-old man with osteosarcoma of the distal tibia. After neoadjuvant chemotherapy, wide excision was performed while preserving the ankle joint. Bone reconstruction by Plate-assisted bone segment transport (PABST) was performed with a non-invasive growing intramedullary nail. At 34 months of follow-up, there was solid union and the Musculoskeletal Tumour Society Score was 26/30. Discussion This is the first report of PABST after distal tibia tumour resection. It shows that this is a viable and safe method of reconstruction. Despite the use of adjuvant chemotherapy, regenerate was formed and union was achieved. Conclusion PABST is a useful tool in the armamentarium to tackle difficult large bone defects. Large distal tibia bone defects are difficult to manage. First report of Plate-assisted bone segment transport after distal tibia tumour resection Regenerate was formed and bone union was achieved despite adjuvant chemotherapy. Good outcome and function at 34 months of follow-up Plate-assisted bone segment transport is a useful reconstructive technique.

Abstract
In this work, a modified dicalcium phosphate dihydrate (DCPD) bone cement with unique biodegradable ability in a calcium phosphate cement system was prepared by the hydration reaction of monocalcium phosphate monohydrate and calcium oxide and integration with pullulan (Pul), a non-toxic, biocompatible, viscous, and water-soluble polysaccharide that has been successfully used to improve defects in DCPD bone cement, especially its rapid solidification, fragile mechanical properties, and easy collapse. The effect of different contents of Pul on the structure and properties of DCPD were also studied in detail. The modified cement was characterised by X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, ultraviolet-visible absorption, X-ray photoelectron spectroscopy analysis, and rheological property measurements. The results indicated that Pul promoted the hydration formation of DCPD, and interface bonding occurred between Pul and DCPD. With increasing content of Pul, the setting time of the DCPD bone cement increased from 2.6 min to 42.3 min, the compressive strength increased from 0 MPa to 20.4 MPa, and the anti-collapse ability also improved owing to the strong interface bonding, implying that the DCPD bone cement improved by Pul has better potential for application in the field of non-loading bone regenerative medicine compared to unmodified DCPD bone cement.

Reconstructive Challenges of Distal Tibia Bone Tumors: Extracorporeally Irradiated Autograft Combined with a Nonvascularized Autograft Fibula for Superior Reconstruction and Functional Outcomes When Compared to Ipsilateral Pedicled Fibula Transfer Alone. Sarcoma 2021; 2021:6624550. [PMID: 33814963 PMCID: PMC8012118 DOI: 10.1155/2021/6624550] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Revised: 03/08/2021] [Accepted: 03/11/2021] [Indexed: 11/17/2022] Open
Abstract
Introduction Traditionally, centralization of the fibula with fusion across the tibiotalar joint has been used to reconstruct distal tibial defects. Although effective, it requires long periods of protected weight-bearing. The fibula or the fixation often fails before fibular hypertrophy necessitating multiple additional surgeries. A method of using ECRT with the available ipsilateral fibula (nonvascularized) to reconstruct the distal tibia defect with the aim of early return to weight-bearing was evolved. This paper documents our early experience. Patients and Methods. Four patients; with the diagnosis of osteosarcoma in 3 patients and recurrent giant cell tumor of the bone in 1 patient, underwent resection of the distal tibia for tumors between 2017 and 2019. Extracorporeally irradiated (50 Gy) distal tibia along with ipsilateral nonvascularized fibula was used to bridge the defect and fuse the tibiotalar joint. A plate was used to rigidly hold the construct. The final outcome was compared to the historical control group that underwent only pedicled ipsilateral fibula transposition and ankle arthrodesis without recycled autograft or allograft between 2009 and 2017. Oncological reconstruction and functional outcomes were compared for each group. Patient reported outcomes on the acceptability of ankle fusion; cosmesis and function were analyzed and compared between the two groups. Results The mean resection length in the study group (4 patients) was 7.75 cm (7 to 8.5 cm). As compared to the historical cohort of 7 patients, the study population showed statistically superior results in all reconstruction, functional, and patient-reported outcomes except time to proximal junction union (p=0.068). There were no reconstruction failures, infection, or nonunions in the study group, whereas the control comparative group had 2 proximal junction nonunions and a mean time to fibular hypertrophy of 143 weeks (82 to 430 weeks) with fibula centralization. Earlier weight-bearing was allowed (mean 26.75 weeks; median 27 weeks) compared to (mean 80.75 weeks; median 80 weeks) in the control group. Conclusion We think that ECRT with ipsilateral vascularized fibula is a promising method of reconstructing the distal tibia. The recycled autograft tibia added strength to the distal tibia construct in our study and aided the anatomical reconstruction of the distal tibia. The patient-reported outcomes for cosmesis and acceptability add to the benefits of performing this procedure. Consistent early union across the proximal junction and earlier weight-bearing were clear advantages of this method.

Abstract
BACKGROUND Conflicting findings have been reported concerning the survival of patients treated with limb salvage and amputation for osteosarcoma. This study aimed to identify predictors associated with surgery types and survival difference. METHODS Patients with osteosarcoma were selected from the Surveillance Epidemiology and End Results database (1975-2016). Multivariable logistic regression analysis was conducted, and a nomogram was further established. Propensity score matching (PSM)-adjusted Kaplan-Meier curves, log-rank tests, Cox proportional hazards regression analysis were performed to compare overall survival (OS) and cancer-specific survival (CSS). RESULTS Among 3363 patients with osteosarcoma, 2447 and 916 underwent limb salvage and amputation. Predictors associated with amputation in the nomogram included age, gender, primary tumor site, tumor grade, tumor stage, tumor size and radiotherapy. Totally 900 pairs of patients treated with limb salvage and amputation were matched after PSM. Limb salvage was significantly associated with improved OS (HR, 0.773; 95% CI, 0.670-0.892; p < 0.001) and CSS (HR, 0.795; 95% CI, 0.681-0.927; p = 0.003) in PSM-adjusted cohort after adjusting for related variables. The significant treatment effect of limb salvage was consistent within most subgroups. Among patients treated with surgery for osteosarcoma, age between 41 and 60, age ≥ 61, pelvis as the primary site, high tumor grade (III/IV), regional and distant tumor stage, tumor size ≥ 92 mm and radiotherapy were independent prognostic factors in PSM cohort. CONCLUSIONS Limb salvage exhibits significant benefit on OS and CSS compared with amputation for osteosarcoma. Predicators and survival differences should be given full consideration for the treatment of osteosarcoma.

Abstract
BACKGROUND We report on a patient with human immunodeficiency virus (HIV)-positive disease with a malignant bone tumor in the left proximal tibia treated with surgery using microwave ablation (MWA). CASE PRESENTATION A 50-year-old Chinese male presented with sudden pain in the left knee and weight loss that had begun 2 months prior to his visit. The preoperative X-ray and MRI scan both demonstrated significant osteolytic destruction in the left proximal tibia surrounded with soft tissue mass. The patient underwent limb salvage surgery for his left leg with the technique of microwave ablation in situ. The pathology revealed myofibroblastic sarcoma with no positive margins, stage T2N0M0. The patient has a satisfactory functional and cosmetic limb with no evidence of disease at a follow-up time of 2 years. CONCLUSION MWA is a feasible and effective surgical method for the limb salvage operation, especially for the patient with poor immunological function, e.g., HIV infection. It might offer an innovative and distinctive therapeutic alternative for malignant bone tumors, while avoiding prosthesis replacement.

Abstract
Background Osteosarcoma is a malignant bone tumor affecting mainly children and young adults and commonly involves extremities. The aim of this study was to assess the patient-related, tumor-related, and treatment-related factors affecting the overall survival in patients with non-metastatic extremity osteosarcoma. Methodology A retrospective, single institutional study of 100 patients with non-metastatic extremity osteosarcoma was done between 2014 and 2019. Age, sex, histologic type, tumor site, use of preoperative chemotherapy and its duration, response to chemotherapy, type of surgery, presence of local recurrence, occurrence of lung metastasis, and survival data were recorded. Survival analysis was done using Kaplan-Meier method. p < 0.05 by log-rank test was considered statistically significant. Statistical data were analyzed using SPSS v.25(IBM). Results The median age of presentation was 18 years with male sex preponderance. The most common site of presentation was distal femur, and commonest histological variant was osteoblastic osteosarcoma. Incidence of local recurrence was 9%, and lung metastasis was identified in 12% on follow-up. The 5-year overall survival (OS) was 65.5%, and 5-year local recurrence-free survival was 57.6%. The 5-year OS in neoadjuvant chemotherapy group was 80% compared to 39.5% in upfront surgery group (p = 0.015). The 5-year OS in patients with tumor necrosis > 90% and < 90% was 93.2% and 71.2%, respectively (p = 0.038). The 5-year OS in patients without lung metastasis was 76%, whereas none who developed lung metastasis has survived 5 years (p < 0.001). Conclusion The use of neoadjuvant chemotherapy, good response to chemotherapy, and the absence of lung metastasis on follow-up can independently predict better overall survival.

Abstract
OBJECTIVE We present data from our recently completed study that suggests that joint salvage is the key parameter in keeping the limb salvage ethos relevant. METHODS We reviewed all patients operated on nationally over 30 years (1978 to 2008). We identified 265 survivors of which 162 were available for evaluation at the time of survey. RESULTS There were 92 males and 70 females followed an average 9.1±SD3.1 years. Average age at survey was 38±SD17 years. ANOVA for mental health and TESS degree of importance for ADL identified that all categories of joint preservation were similar to an average group of people from the population. Physical health scores were significantly better amongst joint-preserved versus joint replacement patients (p = 0.003). Nevertheless, there was no significant difference between amputees with respect to physical health scores compared to arthrodesed and joint-replaced individuals. Biological reconstructions scored significantly better than metallic segmentary reconstructions (p < 0.001). Dissatisfaction appeared to correlate best with the presence of pain following reconstruction (p < 0.001). CONCLUSIONS While our study supports the finding of amputations being as satisfactory as arthrodeses and joint replacement salvage surgery, joint salvage was superior to all other categories. Assessments of equivalence should incorporate joint salvage and materials used as evaluable parameters.

Abstract
AIMS The aim of this study was to report the results of three forms of reconstruction for patients with a ditsl tibial bone tumour: an intercalary resection and reconstruction, an osteoarticular reconstruction, and arthrodesis of the ankle. METHODS A total of 73 patients with a median age of 19 years (interquartile range (IQR) 14 to 36) were included in this retrospective, multicentre study. RESULTS Reconstructions included intercalary resection in 17 patients, osteoarticular reconstruction in 11, and ankle arthrodesis in 45. The median follow-up was 77 months (IQR 35 to 130). Local recurrence occurred in eight patients after a median of 14 months (IQR 9 to 36), without a correlation with adequacy of margins or reconstructive technique. Major complications included fracture of the graft in ten patients, nonunion of the proximal osteotomy in seven, and infection in five. In the osteoarticular group, three of 11 patients developed radiological evidence of severe osteoarthritis, but only one was symptomatic and required conversion to ankle arthrodesis. Functional evaluation showed higher values of the Musculoskeletal Tumour Society (MSTS) and American Orthopaedic Foot and Ankle Society (AOFAS) scores in the intercalary group compared with the others. CONCLUSION Preservation of the epiphysis in patients with a distal tibial bone tumour is a safe and effective form of limb-sparing treatment. It requires rigorous preoperative planning after accurate analysis of the imaging. When joint-sparing resection is not indicated, ankle arthrodesis, either isolated tibiotalar or combined tibiotalar and subtalar arthrodesis, should be preferred over osteoarticular reconstruction.

Limb-salvage surgery offers better five-year survival rate than amputation in patients with limb osteosarcoma treated with neoadjuvant chemotherapy. A systematic review and meta-analysis. J Bone Oncol 2020; 25:100319. [PMID: 33088699 PMCID: PMC7567946 DOI: 10.1016/j.jbo.2020.100319] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 08/26/2020] [Accepted: 09/09/2020] [Indexed: 02/04/2023] Open
Abstract
Background Osteosarcoma is the most common primary bone sarcoma. Currently, the main treatment option for high-grade osteosarcomas is neoadjuvant chemotherapy, followed by surgical resection of the lesion and adjuvant chemotherapy. Limb salvage surgery (LSS) and amputation are the main surgical techniques; however, controversy still exists concerning the best surgical method. Our meta-analysis compared the effectiveness of LSS and amputation combined with neoadjuvant chemotherapy in patients with limb osteosarcoma, in terms of 5-year overall survival (OS), 5-year disease-free survival (DFS) and local recurrence rate. Methods Following the established methodology of PRISMA guidelines, a literature search was conducted in PubMed, Cochrane, Google Scholar from 1975 until January 2020. Two independent reviewers evaluated the study quality based on the Newcastle-Ottawa scale. Odds ratio and 95% confidence interval of the OS, DFS and local recurrence rate were calculated. Results Thirteen studies were finally included with a total of 2884 patients; 1986 patients undergone LSS and 898 amputations. Five-year overall survival was almost 2-fold in patients treated with LSS than those treated with amputation (OR: 1.99; 95% CI: 1.35-2.93; I2 = 74%, p < 0.001). No difference was found in 5-year DFS between LSS patients and amputees (OR: 1.24; 95% CI: 0.55-2.79; I2 = 67%, p = 0.01). The odds of local recurrence was numerically higher in LSS compared to amputation but not statistically significant (OR: 2.29; 95% CI: 0.95-5.53; I2 = 47%, p = 0.05). However, the included studies did not clearly define differences in the stages of patients of the two groups. Conclusion Our study demonstrated that in patients with limb osteosarcoma treated with neoadjuvant chemotherapy, LSS is associated with a higher 5-year overall survival and the odds of local recurrence may be increased but these results should be interpreted with caution due to high heterogeneity.

Abstract
Osteosarcoma (OS) is the most common malignant bone tumor primarily influencing children and adults. Approximately one‐fifth of patients have micrometastasis in the lungs when OS is diagnosed. Platelet‐derived growth factor receptor (PDGFR) beta (PDGFRβ) is a subtype of PDGFR. PDGFRβ has been noted to be highly expressed in OS cell lines and patient specimens, and is associated with metastasis and poor prognosis of OS. However, mechanistic insights into the exact role of PDGFRβ in OS pathogenesis and development are still lacking. Here we assessed the effects of PDGFRβ on invasive and migratory abilities, such as the epithelial–mesenchymal transition and phosphatidylinositol 3‐kinase (PI3K), Akt and mammalian target of rapamycin (mTOR) pathways in HOS cells. Depleting PDGFRβ resulted in reduced migration of HOS cells in the small interfering RNA duplexes specific for the PDGFRβ group compared with the mock and scramble‐treated groups in Transwell invasion assays. Using wound‐healing assays, we demonstrate the rate of wound healing in the PDGF‐BB‐stimulated group was higher compared with the mock‐treated group. Western blot showed that down‐regulation of PDGFRβ decreased the expression of stromal phenotype markers and phosphorylation pathway proteins (PI3K, AKT and mTOR), but the epithelial phenotype marker was increased in HOS cells. Treating HOS cells with PDGF‐BB revealed a treatment time‐dependent increase of phosphorylated, but not total, PI3K, AKT and mTOR. Taken together, we suggest that PDGFRβ plays an important role in OS invasion, migration and epithelial–mesenchymal transition by influencing the PI3K, Akt and mTOR pathways, hence highlighting PDGFRβ as a potential therapeutic target for OS.

Abstract
AIM The aims of this study were to assess survival outcome of pediatric patients with localized osteosarcoma of the extremities in Upper Egypt, identify factors of prognostic significance for survival, and to determine factors predictive of surgical methods used in these patients, as well as developing a clinical model for risk prediction. PATIENTS AND METHODS A retrospective analysis of data assembled from medical records of 30 pediatric patients with a histologically verified nonmetastatic osteosarcoma of the extremities treated at South Egypt Cancer Institute with a unified chemotherapy protocol between January 2001 and December 2015 was carried out. Prognostic factors were determined using univariable and multivariable methods. A model for surgical outcomes in these patients based on the baseline clinical factors, and the parameters predictive of their tumor response to chemotherapy, was developed. RESULTS With a median follow-up of 63 months for the study population, the estimates for event-free survival and overall survival (OS) at 3 and 5 years were 69.5% and 79% and 65.2% and 65.3%, respectively. Age 16 years or above was independently associated with both worse metastasis-free survival (hazard ratio [HR]=6.05, 95% confidence interval [CI]: 1.43-25.6, P=0.015) and OS (HR=7.9, 95% CI: 1.71-36.2, P=0.008). In the multivariable analysis, a proximal location within the limb gained a statistical significance to be independently associated with worse OS (HR=2.4, 95% CI: 1.13-22.1, P=0.003). Poor response to chemotherapy was marginally associated with worse metastasis-free survival (HR=4.9, 95% CI: 1.02-23.8, P=0.047) only in the univariable analysis. The patients found to be more likely to undergo an amputation surgery (odds ratio=14.1, 95% CI: 1.34-149.4, P=0.028) were those in whom a tumor was poorly responding to chemotherapy. CONCLUSION In Upper Egypt, despite the reasonable survival outcomes in nonmetastatic osteosarcoma, a relatively high limb amputation rate has been encountered. The development of a clinical prediction model for future planning of possible outcome improvement in these patients, however, is still feasible.

Abstract
OBJECTIVE To assess the effectiveness of the pasteurized tumor-bearing bone replantation in treatment of primary malignant bone tumor of extremities. METHODS Between February 2012 and June 2016, 13 patients with primary malignant bone tumor of extremities were treated with pasteurized tumor-bearing bone replantation after extensive excision. There were 8 males and 5 females, aged from 11 to 27 years, with an average of 17.4 years. Tumors were located at the mid-upper humerus in 2 cases, the mid-upper femur in 2 cases, the mid-lower femur in 6 cases, the mid-upper tibia in 2 cases, and the middle tibia in 1 case. According to Enneking staging system, 3 patients were classified as stage ⅠB, 5 patients as stage ⅡA, and 5 patients as stage ⅡB. There were 11 cases of osteosarcoma and 2 cases of chondrosarcoma. The disease duration ranged from 3 to 8 months, with an average of 4.8 months. The length of the tumor-bearing bone ranged from 8 to 16 cm, with an average of 12.5 cm. Postoperative follow-up was conducted regularly to evaluate the status of inactivated bone and complications. The limb function was assessed by the Musculoskeletal Tumor Society 93 (MSTS-93) scoring system. RESULTS All 13 patients were followed up 26-79 months, with an average of 50.5 months. Eleven patients survived without tumors. Two patients had local soft tissue recurrence and underwent amputation, 1 had lung metastasis after amputation and died. All patients had no complications of bone resorption, shortening, and internal fixation disorder. The nonunion of osteotomy occurred in 4 cases. Among them, 3 cases were successfully healed after autologous iliac bone grafting, and 1 case was treated conservatively. The healing time of metaphyseal osteotomy end was 10-15 months (mean, 12.6 months), the healing rate was 90.9% (10/11); the healing time of diaphyseal osteotomy end was 12-21 months (mean, 17.0 months), the healing rate was 72.7% (8/11); and the total healing rate of osteotomy end was 81.8% (18/22). One case had inactivated bone fracture and 1 case had incision dehiscence and infection after operation. At last follow-up, the MSTS-93 score of affected limb ranged from 21 to 28, with an average of 25.3. CONCLUSION The procedure of the pasteurized tumor-bearing bone replantation is an effective, simple, and economic way in repair of massive segmental bone defect to save limb function for primary malignant bone tumor of extremities.

Abstract
Osteosarcoma (OSA) is malignant bone tumor, occurring in children and adults, characterized by poor prognosis. Despite advances in chemotherapy and surgical techniques, the survival of osteosarcoma patients is not improving significantly. Currently, great efforts are taken to identify novel selective strategies, distinguishing between cancer and normal cells. This includes development of biomimetic scaffolds with anticancer properties that can simultaneously support and modulate proper regeneration of bone tissue. In this study cytotoxicity of scaffolds composed from poly (L-lactic acid) functionalized with nanohydroxyapatite (nHAp) and doped with europium (III) ions-10 wt % 3 mol % Eu3+: nHAp@PLLA was tested using human osteosarcoma cells: U-2 OS, Saos-2 and MG-63. Human adipose tissue-derived stromal cells (HuASCs) were used as non-transformed cells to determine the selective cytotoxicity of the carrier. Analysis included evaluation of cells morphology (confocal/scanning electron microscopy (SEM)), metabolic activity and apoptosis profile in cultures on the scaffolds. Results obtained indicated on high cytotoxicity of scaffolds toward all OSA cell lines, associated with a decrease of cells' viability, deterioration of metabolic activity and activation of apoptotic factors determined at mRNA and miRNA levels. Simultaneously, the biomaterials did not affect HuASCs' viability and proliferation rate. Obtained scaffolds showed a bioimaging function, due to functionalization with luminescent europium ions, and thus may find application in theranostics treatment of OSA.

Abstract
BACKGROUND AND OBJECTIVES With recent advances in chemotherapy and surgical techniques, the trend in the treatment of osteosarcoma continues to progress towards limb salvage. However, studies comparing limb salvage with amputation continue to be limited by selection bias and small sample sizes. This study utilized propensity-score matching to minimize potential confounders and selection bias to compare the survival rates in patients with osteosarcoma that were treated with amputation vs limb salvage surgery. METHODS The Surveillance, Epidemiology, and End Results Program was utilized to identify all patients with a diagnosis of extremity osteosarcoma. Patients were matched with demographics, tumor characteristics, and treatment information. These variables were then fitted in a multivariate model and hazard ratios (HR) for overall- and disease-specific mortality was calculated. RESULTS A total of 4107 patients were identified, of which, 1538 were left after propensity-score matching. Older age, Black race, upper extremity location, and higher American joint committee on cancer (AJCC) class were associated with worse overall- and disease-specific mortality rates (P ≤ .0389). Compared with their matched counterparts, patients treated with amputation had higher overall mortality (HR 1.677; P < .0001) and higher disease-specific mortality (HR 1.678; P < .0001). CONCLUSION Patients whose tumor characteristics preclude limb salvage have significantly higher overall- and disease-specific mortality rates.

Abstract
Background Reconstruction for large bone defect of distal tibia after wide resection of tumor is difficult, and the best option remains controversial. This study presents a novel “double-strut” fibula ankle arthrodesis for this issue. Methods Nine patients with malignant or aggressive tumors of distal tibia underwent novel “double-strut” fibula ankle arthrodesis after wide tumor resection were retrospectively reviewed. We assessed the bone union time, complications and oncology outcome clinically and radiographically. The Musculoskeletal Tumor Society (MSTS) score and the Foot and Ankle Outcome Score (FAOS) were used to evaluate the functional outcome. Results The average followup period was 53 ± 46 months. There was no deep infection or graft fracture observed in this series. Internal fixation loosening was found in one case. In these patients, eight achieved union at both proximal and distal junctions, while one achieved union only distally. The mean union time of the proximal junctions and distal junctions was 10.5 ± 1.6 months and 8.7 ± 2.3 months, respectively. The mean postoperative MSTS score was 83% ± 8%. The subscales of FAOS indicating the most problem was Sport and Recreation Function with a mean score of 18 ± 11. At the final follow-up, one of them (1/9, 11%) experienced local recurrence in soft tissue and received another resection surgery, and four (4/9, 44%) patients developed lung metastases. Conclusions For large bone defect of distal tibia, this novel “double-strut” fibula reconstruction can be a viable alternative, which is capable of achieving durable ankle fusion and functional salvaged limb with low rate of complications.

Treatment-Related Prognostic Factors in Managing Osteosarcoma around the Knee with Limb Salvage Surgery: A Lesson from a Long-Term Follow-Up Study. BIOMED RESEARCH INTERNATIONAL 2019; 2019:3215824. [PMID: 31187043 PMCID: PMC6521568 DOI: 10.1155/2019/3215824] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/20/2019] [Revised: 03/26/2019] [Accepted: 04/11/2019] [Indexed: 12/18/2022]
Abstract
Purpose The aim of this study was to assess the treatment-related factors associated with local recurrence and overall survival of patients with osteosarcoma treated with limb-salvage surgery. Patients and Methods Treatment-related factors were analyzed to evaluate their effects on local recurrence-free survival (LRFS) and overall survival (OS) in 182 patients from 2004 to 2013. Results The mean length of follow-up was 73.4 ± 34.7 months (median, 68 months; range, 12-173 months), and 63 patients died by the end of the follow-up. The 5-year and 10-year overall survival rates were 68.6 ± 6.6% and 59.4 ± 10.6%, respectively. Univariate analysis showed that treatment-related prognostic factors for overall survival were prolonged symptom intervals >=60 days, biopsy/tumor resection performed by different centers, previous medical history, incomplete preoperative chemotherapy (<8 weeks), and prolonged postoperative interval >21 days. In the multivariate analysis, biopsy/tumor resection performed by different centers, incomplete implementation of planned new adjuvant chemotherapy, and delayed resumption of postoperative chemotherapy (>21 days) were risk factors for poor prognosis; biopsy/tumor resection performed by different centers and tumor necrosis <90% were independent predictors of local recurrence. Conclusion For localized osteosarcoma treated with limb-salvage surgery, it is necessary to optimize timely standard chemotherapy and to resume postoperative chemotherapy to improve survival rates. Biopsies should be performed at experienced institutions in cases of developing local recurrence.

Abstract
INTRODUCTION The Patient-reported Outcomes Measurement Information System (PROMIS) is a scoring tool that allows comparisons between patients with rare conditions and more common ailments, or the general US population. PROMIS outcomes were compared between the limb salvage and amputee patients for nonmetastatic sarcomas to the US population. METHODS One hundred thirty-eight patients were included in the analysis. Patients were divided into the limb salvage and amputee cohorts, as well as based on the follow-up (1 to 11 or 12+ months). RESULTS Seven PROMIS domains were evaluated, and higher scores were found in both the limb salvage group and patients >12 months from surgery. The limb salvage group also had improved emotional health compared with the US population. DISCUSSION Improvements in PROMIS values are observed in limb salvage patients and in patients >12 months from surgery. Limb salvage patients demonstrate improved emotional health compared with the US population.

Abstract
INTRODUCTION This is a retrospective study that evaluate the outcome of patients with extremity sarcoma between extramedullary plate and intramedullary nailing for the biological reconstruction after tumor resection. METHODS 58 patients (40 treated with plate fixation and 18 with intramedullary nailing, IM group) with sarcomas of the lower and upper extremity who received biological reconstruction at our bone tumor center from November 2003 to November 2015 were reviewed for the study. There were 29 male and 29 female patients with a mean age of 20.8 years (range, 5-72 years). The mean follow-up duration was 90.8 months (range, 12.2-244.4 months). All data were obtained from the clinical, radiograph records and follow-up information. The analysis of outcome, survival, local recurrence, function and complications of patients in the plate group and IM group was performed. RESULTS 28 cases in the plate group lived at the last follow-up, of which 26 had no evidence of disease, 2 lived with the pulmonary metastasis, whereas 15 in the IM group lived at the last follow-up, of which all had no evidence of disease and no lived with the pulmonary metastasis. There was no significant difference between the two groups for the prognosis. Meanwhile, there was no significant difference of incidence of nonunion, graft fracture and fixation breakage between the two groups, whereas the time to diaphysis union in the plate group (11.6 ± 2.7 months) was shorter than that in IM group (14.7 ± 4.8 months, P = 0.015). It had the tendency that the time to mechanical complications in the intramedullary nailing group (38.1 ± 39.6 months) was longer than that in the plate group (15.7 ± 13.4 months, P = 0.058,95% CI,-45.6-0.8). Furthermore, the infection occurred in 12 cases and five grafts of them developed the deep infection and the mean time to deep infection was 14.8 ± 20.5 months. Furthermore, the incidence of local recurrence for the patients who had plate fixation was similar to the incidence of patients who had nailing fixation. At the last follow-up, the functional evaluation was performed for 39 patients. There was no significant difference in MSTS and VAS functional score for patients between in the plate group (n = 32) and IM group (n = 7). CONCLUSIONS The findings of the present study showed that intramedullary nailing does not improve the union rate or decrease the incidence of mechanical complications for patients with extremity sarcoma after biological reconstruction. However, intramedullary nailing may have potential advantages on the service life for the biological reconstruction after extremity sarcoma resection.

Abstract
BACKGROUND Limb salvaging surgeries are current surgical treatment of extremity bone sarcomas. Resected bone replacement consists of two main methods; tumor prosthesis versus structural allograft. Biological reconstruction with an allograft is an economic cheap method in young sarcoma patients, however, the surgeons are more convinced with tumor prosthesis replacement. METHODS We evaluated the short-term complications and functional results of 40 patients with aggressive extremity tumors in a retrospective cohort study. The mean age of cases was 25 and we followed them for 24 months. 17 patients underwent tumor prosthesis replacement after wide resection of limb sarcomas. 16 cases had structural allograft reconstruction and 7 patients treated with amputation. We matched confounders including age, sex, blood cell count and chemotherapy treatment in the study groups. RESULTS We found 15 major complications (45.5%) in limb salvage surgeries composing infection, allograft nonunion, allograft fracture, prosthesis fracture, prosthesis loosening and device failure that needed another surgery to be resolved. We had 10 major complications in allograft group (62%) and 5 in tumor prosthesis group (29.4%). Although the rate of complications was higher in allograft group, it didn't statistically indicate strong correlation (Fisher's exact: 0.084). Mean Musculo-Skeletal tumor rating Scale (MSTS) score was 25.8(73.7%) and 22.3(63.7%) in allograft group and prosthesis cases respectively. MSTS score had a normal distribution in the different groups with no significant difference between them. CONCLUSION Although complications were higher in the allograft group, allograft could be offered to bone sarcoma patients, whom are predicted to have short life expectancy.

Abstract
Background The Patient Reported Outcomes Measurement Information System (PROMIS) is a patient-directed system that allows comparisons across medical conditions. With this tool, comparisons can now be made between rare conditions, such as sarcomas, and more common ailments, of the United States general population. This allows comparisons between rare conditions, such as sarcomas, to more common ailments, or even the United States (US) general population. Objectives Our purpose was to use PROMIS to compare outcomes in patients that had undergone resection of a nonmetastatic sarcoma to the US population. Methods One hundred thirty-eight patients were included in the analysis. These patients were divided into early (<2 years) and late follow-up (>2 years). Results We evaluated results from seven health domains and found significantly lower scores in the physical function and depression domains. These differences were present in both the early and late cohorts when compared to the US population. Conclusion While physical function was found to be worse in the sarcoma cohorts, we observed significantly improved levels of depression in these patients when compared to the US population. This finding was maintained over time and is an important reminder that a patient's goals and desires change following a cancer diagnosis and must be taken into consideration when planning treatment and determining a successful outcome.

Abstract
AIMS We retrospectively report our experience of managing 30 patients with a primary malignant tumour of the distal tibia; 25 were treated by limb salvage surgery and five by amputation. We compared the clinical outcomes of following the use of different methods of reconstruction. PATIENTS AND METHODS There were 19 male and 11 female patients. The mean age of the patients was 19 years (6 to 59) and the mean follow-up was 5.1 years (1.25 to 12.58). Massive allograft was used in 11 patients, and autograft was used in 14 patients. The time to union, the survival time of the reconstruction, complication rate, and functional outcomes following the different surgical techniques were compared. The overall patient survival was also recorded. RESULTS Out of 14 patients treated with an autograft, 12 (86%) achieved union at both the proximal and distal junctions. The time to union at both junctions of the autograft was significantly shorter than in those treated with an allograft (11.1 vs 17.2 months, p = 0.02; 9.5 vs 16.2 months, p = 0.04). The complication rate of allograft reconstruction was 55%. The five patients treated with an amputation did not have a complication. Out of the 25 patients who were treated with limb salvage, three (12%) developed local recurrence and underwent amputation. The mean functional Musculoskeletal Tumor Society (MSTS) score after autograft reconstruction was higher than after allograft reconstruction (81% vs 67%; p = 0.06), and similar to that after amputation (81% vs 82%; p = 0.82). The two- and five-year overall rates of survival were 83% and 70%, respectively. CONCLUSIONS This consecutive case series supports the safety of limb salvage and the effectiveness of biological reconstruction after the resection of a primary tumour of the distal tibia. Autograft might be a preferable option. In some circumstances, below-knee amputation remains a valid option.

Abstract
Background Primary malignant or aggressive benign bone tumors rarely occur in distal tibia, and limb salvage remains the mainstay of surgical options. However, reconstruction methods for large bone defect after wide tumor resection in this location are debatable. The purpose of this systematical review is to critically evaluate each reconstruction method regarding the postoperative complications and functional outcome. Methods A systematic review of the 33 studies including 337 cases with tumors affecting distal tibia was performed after searching the PubMed and EMBASE databases. Pooled descriptive statistics with separate analyses for postoperative complications and functional outcome of different reconstruction options were performed. Results 290 (86.1%) patients received limb salvage procedures. Reconstruction strategies including biological reconstruction, such as autograft, allograft, distraction osteogenesis and non-biological prosthetic replacement. The patients received limb salvage procedures tended to have a higher MSTS score (77.1% vs 70.9%, P = .055) and a higher incidence of local relapse (28/290 vs 0/47, P = .052) than those amputated. Biological reconstruction methods provided better functional outcome (78.4% vs 72.2%, P = .017) compared with non-biological prosthetic reconstruction, although similarity of incidence of major complications (51/253 vs 12/37, P = .091). With respect to the comparison between autograft and allograft reconstruction, the autograft seemed to have less major postoperative complications occurrence (27/165 vs 22/78, P = .032), and consequently better functional outcome (MSTS score, 80.2% vs 74.3%, P = .025) than allograft reconstruction. Conclusions Limb salvage results in better functional outcome compared with amputation. Biological reconstruction is more advocated than prosthetics replacement, and furthermore, autograft might be suggested to be the optimal reconstructive method with regard to better postoperative functional outcome and less major complications.

Abstract
BACKGROUND AND AIMS The present standard of care in treating lower extremity soft tissue sarcomas is function-sparing, limb-preserving resection and reconstruction with or without oncological therapy. The aim of this pilot study was to test the suitability and adequacy of the Finnish translations of two functional outcome questionnaires (Toronto Extremity Salvage Score and Musculoskeletal Tumor Society score) and to perform a preliminary investigation of functional outcomes of Finnish lower-limb soft tissue sarcoma patients after operative treatment. MATERIALS AND METHODS Between June 2015 and December 2015, consecutive surgically treated outpatients were asked to participate in the study. Demographic, clinical, surgical, and oncological outcome data were collected. Two functional outcome questionnaires were used (Toronto Extremity Salvage Score and Musculoskeletal Tumor Society scores). A comparative analysis is presented. RESULTS A total of 19 lower-limb soft tissue sarcoma patients with a mean follow-up time of 2 years and 10 months were included. All (n = 19) invited patients participated in the study. Mean age was 62.3 years. In total, 13 had high-grade sarcomas. Eight wounds were closed directly, four used skin grafts, and five required flap reconstructions. One patient required a tumor prosthesis, and one required a rotationplasty. A total of 14 patients received oncological therapy. No problems or difficulties were reported in using and completing the Finnish versions of the Toronto Extremity Salvage Score or Musculoskeletal Tumor Society questionnaires. The overall Toronto Extremity Salvage Score and Musculoskeletal Tumor Society scores were 88 and 76, respectively. CONCLUSION This pilot study suggests that the Finnish versions of the Toronto Extremity Salvage Score and Musculoskeletal Tumor Society questionnaires are suitable for measuring functional outcome after lower extremity soft tissue sarcomas treatment. Functional outcomes vary from moderate to excellent.

Abstract
PURPOSE This study aimed to evaluate the psychometric properties of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) in Iranian osteosarcoma patients and apply this to compare the functional level, quality of life, symptoms and financial burden of the patients who underwent amputation and limb-salvage operations. METHODS This study was conducted at the main referral orthopedic centers in the southwest of Iran from 2006 to 2016. After complete review of medical records, 48 patients were invited to attend the outpatient clinic and participate in the study via initial telephone interview. All data were entered in the Statistical Package for the Social Sciences version 15.0, and p values <0.05 were considered statistically significant. RESULTS In total, 48 patients with extremities osteosarcoma completed the study. Of these, 31 had been treated with limb-salvage operation and 17 had undergone amputation. In functioning subscale, all the mean score of items, except social function, were higher in the limb salvage group than the amputee group. The mean scores (SD) of global health and quality of life were 64.5(13.2) and 61.2± 12.4 in the limb salvage and amputee groups, respectively. In the financial impact subscale, the mean score (SD) in the limb salvage group was 68.8± (29.7) compared to 74.5(25.0) in the amputee group. CONCLUSION Results support the responsiveness of the EORTC QLQ-C30 for Iranian osteosarcoma patients. Applying this questionnaire revealed similar functional outcome, quality of life, symptoms and financial burden between amputation and limb-salvage groups.

Abstract
Background Ewing’s sarcoma is a primary malignant tumor of bone occurring mostly in childhood. Few effective reconstruction techniques are available after wide resection of Ewing’s sarcoma at the distal end of the tibia. Reconstruction after wide resection is especially difficult in children, as it is necessary to consider the growth and activity of the lower limbs. Case presentation A 12-year-old Japanese boy had presented with right lower leg pain at age 8 years. Imaging examination showed a bone tumor accompanied by a large extra-skeletal mass in the distal part of his tibia. The tumor was histologically diagnosed as Ewing’s sarcoma. The patient received chemotherapy, followed by wide resection. Reconstruction consisted of a bone transport method involving external fixation of Taylor Spatial Frame. To prevent infection after surgery, the external fixation pin was coated with iodine. One year after surgery, the patient showed poor consolidation of bone, so iliac bone transplantation was performed on the extended bones and docking site of the distal tibia. After 20 months, tibia formation was good. Three years after surgery, there was no evidence of tumor recurrence or metastases; bone fusion was good, and he was able to run. Conclusions The bone transport method is an effective surgical method of reconstruction after wide resection of a bone tumor at the distal end of the tibia, if a pin can be inserted into the distal bone fragment. Coating external fixation pins with iodine may prevent postoperative infection.

Abstract
BACKGROUND To investigate the effectiveness of tibiotalocalcaneal arthrodesis with a retrograde nail and allograft in limb salvage surgery for patients with distal tibia osteosarcoma. METHODS 5 patients diagnosed as distal tibia osteosarcoma underwent ankle arthrodesis with a retrograde nail in our hospital. During the follow-up, radiographic views of the ankle joint were taken in two planes to assess bone healing and axis alignment. Other measurements of outcomes included procedure-related complications, local recurrence, and metastasis. Functional outcomes were evaluated with the Musculoskeletal Tumor Society (MSTS) scoring system. RESULTS Postoperative complications occurred in 4 patients, including 4 cases of mild subcutaneous fluid and 1 case of screw breakage. All patients showed stable ankle and could stand or walk with the assistance of crutch before the complete union between allograft and host bone. One patient died due to multiple bone and pulmonary metastasis at 1 year after surgery. As for the other 4 patients, they were followed-up regularly for a mean period of 42 months. No local recurrence or distant metastasis occurred in any of these four patients. All the 4 patients expressed satisfaction with the outcome. According to MSTS scale, the mean postoperative functional score was 74.3%±4.4% (range, 70%-81%). CONCLUSIONS Intramedullary retrograde nail for distal tibia osteosarcoma could produce a satisfactory outcome in terms of functional results and complications. Excellent stabilization of the ankle joint can be achieved through this technique, as it allows patients to perform much earlier postoperative weight-bearing exercise.
