RESUMEN
Nodular fasciitis is a benign soft tissue pseudotumour typically occurring in the upper extremities, head and neck, thigh and trunk. It is most commonly seen in subcutaneous locations but also can be present in intramuscular and intermuscular (fascial) locations. Its occurrence in the hand is rare, and while it can occur in close proximity to tendons, its presentation as an intra-tendinous mass has not been previously described. We present a unique and rare case of nodular fasciitis arising within the flexor digitorum profundus (FDP) tendon of the hand in a 16-year-old female. The patient presented with a painful swelling in the volar aspect of the base of her left middle finger, with progressive flexion deformity of the finger. Ultrasound and magnetic resonance imaging revealed a mass within the FDP tendon of the middle finger. An ultrasound-guided biopsy revealed a diagnosis of nodular fasciitis. Given the self-limiting nature of the condition, she was managed conservatively with close clinical and imaging follow-up. This case highlights the importance of considering nodular fasciitis in the differential diagnosis of an intra-tendinous lesion in the hand, even though it is a rare occurrence in this location. The clinical presentation, diagnostic workup, and management of this unique case are discussed, emphasising the potential for its misdiagnosis as a malignancy which can have important implications in management.
RESUMEN
The evidence for the functional outcome of endo- prosthetic replacement (EPR) after tumour resection has been from few cohort studies. A scoping search revealed no systematic review on patient reported outcome measures after EPR around the knee. The purpose of this study was to evaluate the functional outcome of distal femoral and proximal tibial EPR after tumour resection. A systematic review was conducted using the PRISMA guidelines. The search identified 2560 articles from MEDLINE, EMBASE, CINAHL, and Web of Science. 36 studies satisfying the selection criteria were included for data synthesis. Pooled analysis was performed for homogenous studies. Narrative synthesis was performed for all the studies due to heterogeneity in methodological and statistical analysis. Amongst the overall patient population of 2930, mean ages ranged from 18-66 years and the mean follow up periods in the studies ranged from 12 - 180 months. The weighted mean functional outcome was similar for patients who had DFEPR and PTEPR. The functional outcome scores of Rotating Hinge Knee implants (RHK) were significantly greater than that for Fixed Hinge Knee implants (FHK). The weighted mean functional outcome scores were higher after cemented fixation and after primary EPR procedures. The current evidence suggests that functional out- come after EPR in the knee is good, and RHK implants are better than FHK implants. Functional outcome after primary EPR was significantly better than following revision EPR, and this underscores the importance of minimising complications at the primary surgery.

PURPOSE: Describe and compare the functional and oncological outcomes and complications between paediatric and adult patients after intra-lesional treatment of benign tumours of the proximal femur, stabilised with an autologous non-vascularised fibular strut graft (NVFSG). METHODS: Retrospective review including 54 patients with a benign histopathological diagnosis treated between 1987 and 2018. The mean age at operation was 17 years (range, 3 to 37 years) with a median follow-up of 39.5 months (IQR 46.7 months). Patients were grouped according to their age at diagnosis (< 16 years versus ≥ 16 years). Data collection included weight-bearing status, Musculoskeletal Tumour Society (MSTS) score, local recurrence, revision surgery and complications. Local recurrence-free survival (LRFS) and revision-free survival (RFS) were calculated and compared between groups. RESULTS: The median MSTS score for all patients was 98.3% (IQR 6.7%) without a statistically significant difference (p = 0.146) between both groups. The median time to full weight-bearing was 12 weeks (IQR 0 weeks). Local recurrence occurred in five (9%) patients. LRFS for all patients was 96% at 2 years and 88% at 5 years. Although local recurrence was more frequent in the paediatric group, LRFS did not significantly differ (p = 0.155, 95% CI 223.9 to 312.3) between both groups. Reoperation rate was 13% and was indicated for local recurrence, post-operative fracture, graft resorption and avascular necrosis. RFS for all patients was 90% at 2 years and 85% at 5 years. There was no statistically significant difference (p = 0.760, 95% CI 214.1 to 304.6) regarding RFS between both groups. CONCLUSION: The use of an autogenous NVFSG after intra-lesional curettage of benign proximal femoral lesions allows for a biological, structural stabilisation without additional osteosynthesis, hastening weight-bearing and avoiding metalwork-related complications with minimal post-operative morbidity and complications and excellent functional and oncological outcome for both children and adults.

OBJECTIVE: Limb-salvage following resection of bone sarcomas of the foot are challenging due to the complicated anatomy, adjacent neurovascular structures and few durable reconstruction options. METHODS: We retrospectively analysed 50 patients with primary malignant bone sarcoma of the foot who underwent surgery including chondrosarcoma (n = 23), Ewing's sarcoma (n = 14) and osteosarcoma (n = 13). RESULTS: Median follow-up was 68 months. The primary sites were metatarsal (n = 18), phalanges (n = 15), calcaneus (n = 13) and others (n = 4). The 5-year disease-specific survivals were 100, 83 and 83% in chondrosarcoma, Ewing's sarcoma and osteosarcoma, respectively. Below knee amputation, ray/toe amputation, excision and curettage were performed in 21, 24, 2 and 3 patients, respectively. Below knee amputation was performed in 94% of mid/hindfoot tumours. Surgical margins were wide/radical, marginal and intralesional margin in 42, 5 and 3 patients. Three patients (6%) developed local recurrence, whereas, local recurrence was not observed in patients with wide/radical margins. Postoperative complications occurred in 3 patients (6%; surgical site infection n = 2 and delayed wound healing n = 1). Mean MSTS functional score was 26 points (range, 19-30). CONCLUSIONS: Good local control was achieved with acceptable functional outcomes and post-operative complications; almost all mid/hindfoot tumours required below knee amputation achieving wide/radical margins without local recurrence.

There is increasing preference for limb salvage techniques in the management of pediatric musculo- skeletal tumors. This study was aimed at evaluating femoral growth following proximal tibia resection (PTR) and placement of an extendible endoprosthesis with sliding stem. This was a retrospective study. The demographic and clinical data were collected. All the patients with malignant tumors were fully staged and commenced on appropriate chemotherapy. An expected discrepancy of > 3cm was considered substantial enough to warrant extendible prosthesis. Twelve patients who had follow up full length scanogram of the lower limbs were included for the evaluation of femoral growth. The last available scanograms were used for growth comparison of the femur. The age at resection for all twelve patients ranged from 4-13 years. The commonest histological diagnosis was Osteosarcoma. In the twelve patients assessed for the growth of femur, the mean femoral length was 96% [89%-102%] of the unaffected femur. Distal femoral physeal growth continued after implantation of a sliding extendible prosthesis after resection of proximal tibia tumors.

BACKGROUND AND OBJECTIVES: We aimed to identify the overall survival (OS), surgical complications, survival of reconstruction, and functional outcome of patients who underwent extra-articular resection of the shoulder joint for primary bone sarcomas. The OS and local recurrence rates in patients who underwent an amputation were also evaluated for comparison. METHODS: Thirty-two patients treated between 1988 and 2017 were studied. The tumours were located in the humerus in 22 (69%) and scapula in 10 patients (31%). The resection types were Malawer type IV in 6 (19%), type V in 21 (66%), and type VI in 5 patients (15%). Reconstruction was performed with endoprosthesis in 23 patients (72%) while excision arthroplasty with the suspension of the humerus to the clavicle was performed in 9 patients (28%). Surgical margins were wide in 16, marginal in 8, intralesional in 3, and not available in 5 patients. During the study period, 40 patients underwent a forequarter amputation and 11 patients underwent a shoulder disarticulation. RESULTS: The 5-year OS for patients who underwent extra-articular resection of the shoulder joint was 42% which was not statistically different compared with that of patients who underwent amputation (5-year OS = 30%; P = .091). The 5-year survival of the reconstruction was 94%, similar for endoprosthesis and excision arthroplasty. Local recurrence and complications developed in 6 (19%) and 10 patients (31%), respectively. Failures of the reconstruction requiring revision surgery occurred in two patients (6%). Limb salvage was achieved in 30 patients (94%). The median Musculoskeletal Tumour Society functional score was 61% (interquartile range, 57%-70%) and was similar in the endoprosthesis and excision arthroplasty group. CONCLUSIONS: Extra-articular resection of the shoulder joint for bone sarcomas is an effective limb-salvage method. However, local recurrence remains a principal concern.

BACKGROUND AND OBJECTIVES: Should the threshold for orthopaedic oncology surgery during the coronavirus disease-2019 (COVID-19) pandemic be higher, particularly in men aged 70 years and older? This study reports the incidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during, respiratory complications and 30-day mortality during the COVID-19 pandemic. METHODS: This prospective observational cohort study included 100 consecutive patients. The primary outcome measure was 14-day symptoms and/or SARS-CoV-2 test. The secondary outcome was 30-day postoperative mortality. RESULTS: A total of 100 patients comprising 35 females and 65 males, with a mean age of 52.4 years (range, 16-94 years) included 16 males aged greater than 70 years. The 51% of patients were tested during their admission for SARS-CoV-2; 5% were diagnosed/developed symptoms of SARS-CoV-2 during and until 14 days post-discharge; four were male and one female, mean age 41.2 years (range, 17-75 years), all had primary malignant bone or soft-tissue tumours, four of five had received immunosuppressive therapy pre-operatively. The 30-day mortality was 1% overall and 20% in those with SARS-CoV-2. The pulmonary complication rate was 3% overall. CONCLUSIONS: With appropriate peri-operative measures to prevent viral transmission, major surgery for urgent orthopaedic oncology patients can continue during the COVID-19 pandemic. These results need validating with national data to confirm these conclusions.

AIM: The aim of this study was to determine the oncologic, functional, and clinical outcomes after the extra-articular resection and limb-salvage reconstruction of the hip joint. METHODS: A retrospective study of 34 patients who underwent extra-articular resection of the hip joint for bone sarcomas between 1996 and 2016 was conducted. The primary tumor site was pelvis in 26 patients (76%) and femur in eight (24%). RESULTS: The surgical margins achieved were clear in 31 (91%) patients, and seven (21%) patients developed local recurrence; mostly occurring in pelvic tumors (n = 6). The 3-year overall survival was 63% with a median follow-up of 38 months (range, 5-219), which showed no statistical difference in tumor location. The most common complication was deep infection (n = 7) and dislocation (n = 7), mostly seen in pelvic tumors. Implant failure was seen in two patients with pelvic tumors, while no failure was noted in patients with femoral tumors. The median Musculoskeletal Tumour Society score was 69%; 67% for pelvic tumors and 73% for femoral tumors (P = .535). CONCLUSION: Despite complex surgery, extra-articular resection of the hip joint can achieve oncologically and functionally acceptable outcomes. While tumors of the pelvis are associated with a higher incidence of infection and local recurrence after resection, resection of tumors involving the femur are well tolerated.
RESUMEN
BACKGROUND AND OBJECTIVES: Expandable distal femur prostheses have become more popular over the last decades, but scientific data is limited. METHODS: A retrospective study was performed, including cases treated between 1986 and 2019 in 15 European referral centers for bone sarcomas. RESULTS: A total of 299 cases were included. Average follow-up was 80 months (range, 8-287 months). Mean patient age was 10 years. Most (80%) of the implants were noninvasive growers and a fixed hinge knee was used more often (64%) than a rotating hinge. Most prosthetic designs showed good (>80%) implant survival at 10 years, but repeat surgery was required for 63% of the patients. The most frequent reason for revision procedure was the completion of lengthening potential. Noninvasive expandable implants showed less risk of infection compared to invasive growers (11.8% vs 22.9% at 10 years). No difference in aseptic loosening was found between cemented and uncemented stems. CONCLUSIONS: This study shows the increasing popularity of expandable distal femur prostheses, with overall good results for function and implant survival. However, repeat surgery is frequently required, especially in patients under the age of 10 years old. Infection is less frequent in noninvasive growers compared to implants that require invasive lengthening procedures.
RESUMEN
PURPOSE: Factors affecting long-term outcomes of synovial sarcoma (SS) remain unknown. Here, we aimed to investigate the long-term oncological outcomes and prognostic factors in a large group of patients with surgically-treated localized SS. PATIENTS AND METHODS: Between 1980 and 2011, 191 patients (94 males and 97 females) were treated at a single hospital with a minimum follow-up of 5 years for survivors. The median age was 35 years (range, 3-80 years), and the median follow-up period was 83 months (range, 3-235 months). RESULTS: Disease-specific survival was 76.4% and 60.4% at 5 and 10 years, respectively. Local recurrence occurred in 23 patients at a median of 33 months (range, 6-158 months), and metastasis occurred in 73 patients at a median of 20 months (range, 2-166 months). In multivariate analysis, grade 3 tumors sized ≥5 cm were significantly associated with worse survival. Ten patients (5.2%) developed metastasis more than 5 years after surgery. CONCLUSION: Tumor size and grade govern prognosis in surgically-treated localized SS in long-term settings. If adequately treated patients have not developed metastases for 5 years after surgery, the risk of subsequently developing metastases was lower than previously reported.

AIMS: The aim of this study is to assess outcomes of patients ≤12 years who undergo Stanmore noninvasive extendible endoprosthetic replacement of the distal femur (DF NIEPR). PATIENTS AND METHODS: A total of 101 children (mean age 9.6 years) were included. All complications which required further surgery were recorded. Clinical and functional outcomes were evaluated with Musculoskeletal Tumor Society (MSTS) scores at a mean follow-up of 64 months (range 6-174). RESULTS: Thirty-one (30.7%) patients died at a mean of 33 months. Forty had prosthesis removed after a mean of 43 months (range, 7-103). Attaining of the full lengthening potential before skeletal maturity was the most frequent reason for revision surgery, particularly in those with smaller lengthening potential (P = 0.039). Implant survival rate for other causes was 61.7% at 5 years and 45.0% at 10 years. At final follow-up mean MSTS score was 26 (range, 13-29). Twenty-two (21.5%) patients had a final limb-length discrepancy (LLD) > 2 cm. CONCLUSIONS: DF NIEPR produces a good functional outcome, with the prevention of major LLD at skeletal maturity in the majority of the cases. We suggest patient selection criteria to account for the stage of the disease due to the high cost of the NIEPR, and high percentage requiring revision, and a 60% mortality rate in those patients presenting with distant disease burden.

INTRODUCTION: Epithelioid sarcoma (ES) has a tendency to locally recur, spread proximally, and metastasize, in particular to lymphnodes and lungs. The aim of this report is to study the role of surgery and the extent of margins required for optimal management of patients with localized epithelioid sarcoma of the extremities. MATERIAL AND METHODS: We retrospectively evaluated 77 patients affected by ES of the extremities treated at two different Institutions. RESULTS: Twenty-two patients had metastasis at diagnosis. Estimated survival was 65.5% at 5 years and 50.9% at 10 years, with a better prognosis in patients with localized disease at diagnosis (P < 0.001). Among patients with localized disease, a significantly better survival was found in patients with primary tumors in which radical surgical margins were achieved (P = 0.043). Among 47 patients presenting with primary tumors, local recurrence-free rate was 72.9% at 5 years, and 61.9% at 10 years, with a better local control achieved in patients with radical margins were achieved (P = 0.026). DISCUSSION: We believe that the best approach to improve both local control and survival is to aim for radical margins in patients with primary tumors. Therefore, the best chance for cure is if the first treatment is the right treatment, which we believe to be radical margins.

BACKGROUND: The proximal tibia is one of the most challenging anatomic sites for extremity reconstructions after bone tumor resection. Because bone tumors are rare and large case series of reconstructions of the proximal tibia are lacking, we undertook this study to compare two major reconstructive approaches at two large sarcoma centers. QUESTIONS/PURPOSES: The purpose of this study was to compare groups of patients treated with endoprosthetic replacement or osteoarticular allograft reconstruction for proximal tibia bone tumors in terms of (1) limb salvage reconstruction failures and risk of amputation of the limb; (2) causes of failure; and (3) functional results. METHODS: Between 1990 and 2012, two oncologic centers treated 385 patients with proximal tibial resections and reconstruction. During that time, the general indications for those types of reconstruction were proximal tibia malignant tumors or bone destruction with articular surface damage or collapse. Patients who matched the inclusion criteria (age between 15 and 60 years old, diagnosis of a primary bone tumor of the proximal tibia treated with limb salvage surgery and reconstructed with endoprosthetic replacement or osteoarticular allograft) were included for analysis (n = 149). In those groups (endoprosthetic or allograft), of the patients not known to have reached an endpoint (death, reconstructive failure, or limb loss) before 2 years, 85% (88 of 104) and 100% (45 of 45) were available for followup at a minimum of 2 years. A total of 88 patients were included in the endoprosthetic group and 45 patients in the osteoarticular allograft group. Followup was at a mean of 9.5 (SD 6.72) years (range, 2-24 years) for patients with endoprosthetic reconstructions, and 7.4 (SD 5.94) years for patients treated with allografts (range, 2-21 years). The following variables were compared: limb salvage reconstruction failure rates, risk of limb amputation, type of failures according to the Henderson et al. classification, and functional results assessed by the Musculoskeletal Tumor Society system. RESULTS: With the numbers available, after competitive risk analysis, the probability of failure for endoprosthetic replacement of the proximal tibia was 18% (95% confidence interval [CI], 10.75-27.46) at 5 years and 44% (95% CI, 31.67-55.62) at 10 years and for osteoarticular allograft reconstruction was 27% (95% CI, 14.73-40.16) at 5 years and 32% (95% CI, 18.65-46.18) at 10 years. There were no differences in terms of risk of failures at 5 years (p = 0.26) or 10 years (p = 0.20) between the two groups. Fifty-one of 88 patients (58%) with proximal tibia endoprostheses developed a reconstruction failure with mechanical causes being the most prevalent (32 of 51 patients [63%]). A total of 19 of 45 osteoarticular allograft reconstructions failed (42%) and nine of 19 (47%) of them were caused by early infection. Ten-year risk of amputation after failure for endoprosthetic reconstruction was 10% (95% CI, 5.13-18.12) and 11% (95% CI, 4.01-22.28) for osteoarticular allograft with no difference between the groups (p = 0.91). With the numbers available, there were no differences between the groups in terms of the mean Musculoskeletal Tumor Society score (26.58, SD 2.99, range, 19-30 versus 27.52, SD 1.91, range, 22-30; p = 0.13; 95% CI, -2,3 to 0.32). Mean extension lag was more severe in the endoprosthetic group than the osteoarticular allograft group: 13.56° (SD 18.73; range, 0°-80°) versus 2.41° (SD 5.76; range, 0°-30°; p < 0.001; 95% CI, 5.8-16.4). CONCLUSIONS: Reconstruction of the proximal tibia with either endoprosthetic replacement or osteoarticular allograft appears to offer similar reconstruction failures rates. The primary cause of failure for allograft was infection and for endoprosthesis was mechanical complications. We believe that the treating surgeon should have both options available for treatment of patients with malignant or aggressive tumors of the proximal tibia. (S)he might consider an allograft in a younger patient to achieve better extensor mechanism function, whereas in an older patient or one with a poorer prognosis where return to function and ambulation quickly is desired, an endoprosthesis may be advantageous. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: Controversy exists regarding the ideal method of reconstruction after proximal humeral resection and several reconstructive techniques have been reported. The reconstructive options are very limited when resection of the entire humerus is required. One option is endoprosthetic reconstruction, but there have been few published studies on the outcome of total humeral endoprosthetic reconstruction. QUESTIONS/PURPOSES: The purposes of this study were (1) to assess the longevity of total humerus prostheses in those patients who survived their disease; (2) to review the complications associated with this prosthesis; and (3) to assess the Musculoskeletal Tumor Society functional score in survivors. METHODS: Thirty-four patients (10 males, 24 females) with a mean age of 26 years (range, 7-86 years) were included in this study. Histological diagnosis was osteosarcoma in 15 patients, chondrosarcoma in seven, Ewing's sarcoma in seven, metastatic carcinoma in three, liposarcoma in one, and giant cell tumor of bone in one remaining patient. Twenty-nine patients had their total humeral endoprosthetic replacement for primary reconstruction, whereas the remaining five patients received their implants for failures with other reconstructive techniques. At a minimum followup of 3 months (mean, 8.2 years; range, 3 months to 29 years), 16 patients were alive with no evidence of disease, whereas 13 of the remaining 18 died with metastatic disease. Local recurrence was seen in five patients and all eventually died of disease progression. RESULTS: According to the Kaplan-Meier survival analysis, the cumulative 10-year implant survival rate was 90%. Periprosthetic infection was seen in four patients, postoperative radial nerve palsy in one, and proximal migration of the prosthesis in three, whereas three patients needed a change of the articular elbow bushings at a mean of 16 years after the implant insertion. The mean Musculoskeletal Tumor Society functional score of the 28 patients who survived their disease for more than 12 months after the index procedure and could therefore be functionally assessed was 83% (range, 60%-93%). CONCLUSIONS: From this small, preliminary report, we suggest that total humeral endoprosthetic replacement may be a reasonable option of reconstruction after tumor resection. We have shown that this prosthesis preserves the function of the hand. The local recurrence rate observed suggests that careful selection of patients is crucial. Infection was our most common surgical complication, but we showed that in those who survived their tumor, this prosthesis offers a method to preserve a functional upper extremity in some patients. Further study with more patients is necessary to confirm the value of this reconstruction method. LEVEL OF EVIDENCE: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

PURPOSE: The aim of the study was to report overall survival, local recurrence and development of metastasis in a group of patients with femur chondrosarcoma that presented with or without a pathological fracture. METHODS: A retrospective review was performed, and 182 patients (39 pathological fractures) that had been treated by oncologic surgery for femoral chondrosarcoma were included. The mean age of the series was 50 years (range, eight to 90) and 114 patients were male (63%). Mean follow-up was 113 months (range, three to 216). Cancer-specific overall survival, development of metastasis and local recurrence were analysed, grouping patients by grade (grade I / grade 2-3 / dedifferentiated). RESULTS: Disease-specific survival in the entire group of chondrosarcoma of the femur was 69% (CI95% 63-76) at 5 years. Five-year disease-specific survival in the fracture group was 49% lower than in the control group 75% (p = 0.0001). Survival of patients with grade 1 chondrosarcoma with fracture was significantly less than those without fracture (p = 0.02) but there was no difference in those with grade 2-3 (p = 0.49) and dedifferentiated tumours (p = 0.09). The local recurrence rate of the entire series was 27%. Only dedifferentiated chondrosarcomas with an associated pathological fracture had a significantly higher rate of local recurrence. There was no relationship between development of metastases and fracture. CONCLUSION: A pathological fracture of the femur has a negative prognostic influence in grade 1 chondrosarcoma and increases the risk of local recurrence in dedifferentiated femur chondrosarcomas.

Chondrosarcoma is the second most common surgically treated primary bone sarcoma. Despite a large number of scientific papers in the literature, there is still significant controversy about diagnostics, treatment of the primary tumour, subtypes, and complications. Therefore, consensus on its day-to-day treatment decisions is needed. In January 2024, the Birmingham Orthopaedic Oncology Meeting (BOOM) attempted to gain global consensus from 300 delegates from over 50 countries. The meeting focused on these critical areas and aimed to generate consensus statements based on evidence amalgamation and expert opinion from diverse geographical regions. In parallel, periprosthetic joint infection (PJI) in oncological reconstructions poses unique challenges due to factors such as adjuvant treatments, large exposures, and the complexity of surgery. The meeting debated two-stage revisions, antibiotic prophylaxis, managing acute PJI in patients undergoing chemotherapy, and defining the best strategies for wound management and allograft reconstruction. The objectives of the meeting extended beyond resolving immediate controversies. It sought to foster global collaboration among specialists attending the meeting, and to encourage future research projects to address unsolved dilemmas. By highlighting areas of disagreement and promoting collaborative research endeavours, this initiative aims to enhance treatment standards and potentially improve outcomes for patients globally. This paper sets out some of the controversies and questions that were debated in the meeting.

INTRODUCTION: Anaemia is present in more than 30 % of patients with various cancers at the time of initial presentation. Anaemia or a lower level of haemoglobin (Hb) is an indicator of poorer prognosis in many cancers. Several studies have also demonstrated that high levels of proinflammatory cytokines contribute to the development of anaemia. However, no studies have assessed the correlation between anaemia and survival in patients with soft tissue sarcoma. The aim of this study was to elucidate the relationship between anaemia and clinical outcome and to determine whether pretreatment anaemia predicted disease-specific survival in patients with adult soft tissue sarcoma. METHODS: A total of 376 patients between 2003 and 2010 were retrospectively reviewed. Patients who presented with metastases or/and local recurrence at diagnosis were excluded from this study. RESULTS: Hb levels varied from 8.0 to 17.3 g/dl in all patients. Pretreatment anaemia was seen in 114 patients. Hb levels were significantly correlated to C-reactive protein levels (Spearman ρ = -0.54, p < 0.0001). The tumour histological grade, age and tumour size were also significantly correlated to Hb levels. Patients with anaemia had a worse disease-specific survival (52.6 % at 5 years) than those without anaemia (79.7 % at 5 years) (p < 0.0001). Patients with anaemia also had a worse event-free rate (44 % at 5 years) than those without anaemia (66.3 % at 5 years) (p < 0.0001). Multivariate analysis showed that anaemia remained an independent predictor of survival (p = 0.002) and events (p = 0.0003). CONCLUSION: Pretreatment anaemia may be indicative of an aggressive characteristic in patients with soft tissue sarcoma. We recommend the routine measurement of Hb level to identify patients who are at greater risk of death or an event.

PURPOSE: We report the outcome of intercalary resection of the femoral diaphysis and extracorporeal irradiated autologous bone graft reconstruction, without the use of vascularized fibular graft. METHODS: Six patients with Ewing sarcoma of the mid-shaft femur who were treated by limb sparing tumour resection and reconstruction with extracorporeal irradiated autologous bone graft with intramedullary cement between 2002 and 2010 were studied. RESULTS: Mean age at the time of surgery was ten years (range, four-23). The length of resected femoral bone averaged 23 cm (15-32 cm). The ratio of bone resection length to total femoral length averaged 60 % (56-66 %). The patients had been followed up for between 16 and 79 months (mean, 41 months) at the time of the study. There was no infection nor fracture in this series. Primary union of the distal and proximal osteotomy sites was achieved in three patients. Delayed union of the proximal osteotomy site occurred in one patient that was successfully treated with iliac crest bone grafting. One patient developed non-union at the distal osteotomy site which failed to heal with bone grafting and was therefore converted to endoprosthetic replacement, and another patient was converted to rotationplasty at five months post-surgery because of contaminated margins. Function was excellent in all patients with surviving re-implanted bone. Local recurrence arose in one patient. CONCLUSION: Our experience suggests that cement augmentation of extracorporeal irradiated and re-implanted bone autografts offer a useful method of reconstructing large femoral diaphyseal bone defects after excision of primary malignant bone tumours.

PURPOSE: We report on a group of patients with tumours in the Hoffa's fat pad (HFP), their clinical presentation, histological type and treatment, including two synovial sarcomas with their clinical follow-up, which have not been described previously in the literature. METHODS: We performed a retrospective review of our prospectively collected database of 25 cases of HFP tumours with at least six months follow-up. RESULTS: The gender, age at presentation (over and under 16 years of age), clinical features, history of trauma, treatment chosen, and complications were recorded. The mean age of the patients was 32 years (three to 47). Six patients were under 16 years old. Pain was the most common symptom, present in 92% (n = 23/25). The final diagnoses included 23 (92%) benign tumours and two (8%) malignant tumours. The most common benign tumour was pigmented villonodular synovitis (PVNS) (48% n = 12). The two malignant tumours were synovial sarcomas and both presented in patients under 16 years old. CONCLUSIONS: Hoffa's fat pad tumours are an uncommon and rarely diagnosed group of lesions that can be misinterpreted as any knee pathology. Although the majority of HFP tumours are benign, malignant tumours should be considered in the differential diagnosis for the paediatric population.

BACKGROUND/PURPOSE: Limb preserving surgery for the treatment of patients with osteosarcoma younger than 10 years old is challenging and some authors have advocated amputation to reduce the risk of complications. The aim of this study was to compare the clinical outcomes and surgical complications of patients with osteosarcoma of the extremity aged <10 years old who were treated with limb salvage and amputation. PATIENTS AND METHODS: Retrospective review of patients aged <10 years old who were treated for primary osteosarcoma of bone between 2000 and 2018. RESULTS: We analyzed 82 consecutive patients (32 males, 50 females; median age 8, range 3-9 yrs). Limb-salvage surgery (LSS; n = 65, 79%) and amputation (n = 17, 21%) were performed. Fourteen patients had metastasis at surgery. In patients without metastasis at surgery, the metastasis-free and overall survival rates at 5 years following LSS vs. amputation were 75% vs. 58% (p = 0.162) and 71% vs. 55% (p = 0.516), respectively. The 2-year and 5-year OS rates of the LSS and amputation groups of patients with metastasis at surgery were 88% versus 83% and 50% versus 0%, respectively (p = 0.180). The overall complication rates were 46% post-LSS with 31% requiring re-operation versus 12% post-amputation, with 6% requiring re-operation (p = 0.010). CONCLUSION: The prognosis of patients with localized osteosarcoma aged <10 years undergoing LSS is similar to those treated with amputation, but LSS is associated with a higher risk of complications and subsequent re-operation. LEVEL OF EVIDENCE: Level III.
