There were no focal neurological signs and lumbar spine movements were normal. However, she did have some pain inhibition in her proximal muscles and difficulty weight bearing in her leg. Lumbar spine x-rays showed grade II spondylolytic spondylolisthesis at L5/S1. MR scan of the lumbar spine confirmed this with some facet joint degeneration. She was sent back for more physiotherapy. Six months later she presented with increasing pain in the right hip and a lump in the right groin. Subsequent MR scan showed a large 20cm x 15cm x 10cm lobulated soft tissue mass within the right obturator space extending through the foramen to lie in the adductor space with infiltration into right hip joint. She had a radical resection but later developed lung metastases.

Reconstruction of pelvic bone defect after resection for bone tumours is a challenging procedure especially when the hip joint is involved due to the anatomy and the complex biomechanical and structural function of the pelvic ring. This surgery is associated to high complication rate. The additive 3D printing technology allows us to produce trabecular titanium custom based implants with an accurate planning of resection using bone cutting jigs. From August 2013 to January 2017, we treated 8 patients for bone

Limb Salvage surgery is the preferred treatment for malignant tumours of bone. This may require resection – arthrodesis, endoprosthetic replacement or allograft reconstruction. We have re-implanted the patient’s bone for reconstruction of the defect after debulking the tumour and irradiation in ten patients. All had grade IIB sarcomas of the pelvis, humerus, tibia and metacarpal. Median overall survival was 24 months (maximum 69 months). Four patients are alive at the most recent follow-up. One of them has metastatic disease and local recurrence while others remain free of disease. One patient has had pathological fracture through the irradiated bone that healed with conservative measures. One developed avascular necrosis of the femoral head and required resurfacing arthroplasty of the hip. The

Controversy exists as to what should be considered a safe resection margin to minimize local recurrence in high-grade pelvic chondrosarcomas (CS). The aim of this study is to quantify what is a safe margin of resection for high-grade CS of the pelvis. We retrospectively identified 105 non-metastatic patients with high-grade pelvic CS of bone who underwent surgery (limb salvage/amputations) between 2000 and 2018. There were 82 (78%) male and 23 (22%) female patients with a mean age of 55 years (26 to 84). The majority of the patients underwent limb salvage surgery (n = 82; 78%) compared to 23 (22%) who had amputation. In total, 66 (64%) patients were grade 2 CS compared to 38 (36%) grade 3 CS. All patients were assessed for stage, pelvic anatomical classification, type of resection and reconstruction, margin status, local recurrence, distant recurrence, and overall survival. Surgical margins were stratified into millimetres: < 1 mm; > 1 mm but < 2 mm; and > 2 mm.Aims
Methods
Introduction. The pelvis has always been a difficult area for surgeons, with high complication rates from surgery and the perception of poor oncological outcomes. The aim of the study was to look at the surgical and oncological outcomes of pelvic tumours treated at our centre. Methods. From the 3100 primary bone tumours seen at the ROH. Information was retrieved on 539 patients seen with a primary bone tumour of the pelvis. The demographic details, oncological and surgical outcomes were reviewed. Results. The mean age at presentation (39 yrs old) and duration of symptoms prior to diagnosis (30 weeks) were both significantly greater than the appendicular skeleton. The volume at resection was 3.8 times greater than the appendicular skeleton. The rates of wide surgical margins and response to chemotherapy were significantly poorer (p<0.05) than the appendicular skeleton resulting in rates of local recurrence (27% vs 12%, p<0.05) and overall survival that were poorer that the appendicular skeleton (51% vs 31% 10 yr survival, p<0.05). The dilemma of treating pelvic ewings will be discussed together with the subanalysis of the EICESS 92/EUROEWING 99 trials in relation to

Trochlear dysplasia is a developmental condition characterised by an abnormally flat or dome shaped trochlea and is an important contributing factor to patellofemoral instability and recurrent patellar dislocation. We prospectively studied a cohort of 54 consecutive patients (59 knees) with patellofemoral instability secondary to trochlear dysplasia, treated with a trochleoplasty by a single surgeon over a 5 year period. Patients were recruited from the senior author's specialist knee clinic and pre-operatively, multiple patient-centred scores were recorded. After the trochleoplasty, these were repeated along with a patient satisfaction questionnaire. Of the 54 patients and 59 knees operated, 39 of the patients (44 knees) were female and 15 (15 knees) male and 40 patients (42 knees) had follow-up of 12 months or more. Their mean age at surgery was 21 years and 6 months and mean length of follow up 2 years. One patient was unable to attend for follow up due to the development of a
The aim of this study was to investigate the local recurrence rate at an extended follow-up in patients following navigated resection of primary pelvic and sacral tumours. This prospective cohort study comprised 23 consecutive patients (nine female, 14 male) who underwent resection of a primary pelvic or sacral tumour, using computer navigation, between 2010 and 2012. The mean age of the patients at the time of presentation was 51 years (10 to 77). The rates of local recurrence and mortality were calculated using the Kaplan–Meier method.Aims
