Biological reconstruction techniques after diaphyseal tumour resection have increased in popularity in recent years. High complication and failure rates have been reported with intercalary allografts, with recent studies questioning their role in limb-salvage surgery. We developed a technique in which large segment allografts are augmented with intramedullary cement and fixed using compression plating. The goal of this study was to evaluate the survivorship, complications and functional outcomes of these intercalary reconstructions. Forty-two patients who had reconstruction with an intercalary allograft following tumour resection between 1989 and 2010 were identified from our prospectively collected database. Allograft survival, local recurrence-free, disease-free and overall survival were assessed using the Kaplan-Meier method. Patient function was assessed using the Musculoskeletal Tumour Society (MSTS) scoring system and the Toronto Extremity Salvage Score (TESS). The 23 women and 19 men had a mean age of 33 years (14–77). The most common diagnoses were osteosarcoma (n=16) and chondrosarcoma (n=9). There were 9 humerus, 18 femur and 15 tibia reconstructions. At a mean follow-up of 95 months (5–288), 31 patients were alive without disease, 10 were dead of disease and 1 was deceased of other causes. There were 4 local recurrences and 11 patients developed metastatic disease. 5-year local recurrence free survival was 92%, 5-year disease-free survival was 70% and overall survival was 75%. Fourteen of 42 patients (33%) experienced complications: 5 wound healing complications, 4 infections, 2 non-unions, 2 fractures and 1 nerve palsy. Four allografts (9.5%) were revised for complications and 2 (5%) for local recurrence. Mean allograft survival was 85 months (4–288). Mean time to union was 8.2 (3–36) months for the proximal osteotomy site and 8.1 (3–23) months for the distal osteotomy site. The mean score for MSTS 87 was 29.4 (+/− 4.4), MSTS 93 was 83.7 (+/−14.8) and TESS was 81.6 (+/−16.9). An intercalary allograft augmented with intramedullary cement and compression plate fixation provides a reliable and durable method of reconstruction after tumour resection. Complication rates are comparable to the literature and are associated with high levels of patient function and satisfaction

The purpose of this study is to present a series of soft tissue sarcomas requiring complex vascular reconstructions, and to describe their management and outcomes. Soft tissue sarcomas are rare mesodermal malignancies accounting for approximately 1% of all cancers diagnosed annually. Sarcomas involving the pelvis and extremities are of particular interest to the orthopaedic surgeon. Tumours that encase and invade large calibre vascular structures present a major surgical challenge in terms of safety of excision with acceptability of surgical margins. Technical advances in the fields of both orthopaedic and vascular surgery have resulted in a trend towards limb salvage with vascular reconstruction in preference to amputation. Limb-salvage surgery is now feasible due to the variety of reconstructive options available to the surgeon. Nevertheless, surgery with concomitant vascular reconstruction is associated with higher rates of complications including infection and amputation. We present a case series of soft tissue sarcomas with vascular compromise, requiring resection and vascular reconstruction. We treated four patients (n = 4, three females, and one male) with soft tissue masses, which were found to involve local vascular structures. Histology revealed leiomyosarcoma (n = 2) and alveolar soft part sarcomas (n = 2). Both synthetic graft and autogenous graft (long saphenous vein) techniques were utilised. Arterial reconstruction was undertaken in all cases. Venous reconstruction was performed in one case. One patient required graft thrombectomy at one month post-operatively for thrombosis. We present a series of complex tumour cases with concomitant vascular reconstructions drawn from our institution's experience as a national tertiary referral sarcoma service

Aims. Present the outcomes of those patients diagnosed with Ewing's Sarcoma of the foot within the past 10 years and treated at the Royal National Orthopaedic Hospital's Bone Tumour Unit, Stanmore. Methods. Retrospective study of the cases identified from the pathology database. Notes reviewed for presentation, treatment and follow up. TESS (Toronto Extremity Salvage Score) and MSTS (Musculoskeletal tumour score) were calculated. Results. 6 patients identified with positive diagnosis of Ewing's Sarcoma of the Foot. Male:Female ratio of 5:1. Age range 15–31 (Mode 25). 4 cases skeletal, 2 extra skeletal. All cases reviewed by supra-regional MDT and received adjuvant and neo-adjuvant chemotherapy. All except one patient underwent limb-salvage surgery. The MDT decision for the remaining patient was that amputation was the only viable surgical option but the patient and his parents requested radiotherapy without surgical treatment. Mean survival 40 months (15–107 months). All patients survive at time of submission. Mean MSTS/TESS scores 93% (80–100%) and 94.6% (85–100) respectively. Discussion. All patients reported a delay between first presentation and referral to the sarcoma unit. This experience is common across the literature for this rare pathology. Lowest scores were submitted by the two patients who had amputation of their great toe. All patients are happy with their outcome and decision to salvage their limb. All patients scored themselves as “not at all disabled” and two stated this would not have been their response if they had lost their foot. Conclusion. Amputation is psychologically difficult to accept and patients are more receptive to limb salvage surgery. Our patients demonstrate good functional outcome. Our experience at Stanmore suggests that limb salvage surgery with adequate MDT surveillance for Ewing's Sarcoma of the Foot can be a viable alternative to amputation
