Needle biopsy is an established technique for the histological diagnosis of bone tumours, usually guided by fluoroscopy or CT. Surface lesions and aggressive tumours which have extended through the cortex are also amenable to imaging with ultrasound (US). We have assessed the diagnostic accuracy of US-guided Trucut needle biopsy in a consecutive series of patients referred to a Bone Tumour Unit with suspected

There is insufficient evidence to support bony reconstruction of the pubis after a type III internal hemipelvectomy (resection of all or part of the pubis). In this study, we compared surgical complications, postoperative pain, and functional outcome in a series of patients who had undergone a type III internal hemipelvectomy with or without bony reconstruction. In a retrospective cohort study, 32 patients who had undergone a type III hemipelvectomy with or without allograft reconstruction (n = 15 and n = 17, respectively) were reviewed. The mean follow-up was 6.7 years (SD 3.8) for patients in the reconstruction group and 6.1 years (SD 4.0) for patients in the non-reconstruction group. Functional outcome was evaluated using the Musculoskeletal Tumor Society (MSTS) scoring system and the level of postoperative pain with a visual analogue scale (VAS).Aim
Methods
The consensus is that bipolar hemiarthroplasty (BHA) in allograft-prosthesis composite (APC) reconstruction of the proximal femur following primary tumour resection provides more stability than total hip arthroplasty (THA). However, no comparative study has been performed. In this study, we have compared the outcome and complication rates of these two methods. In a retrospective study, 57 patients who underwent APC reconstruction of proximal femur following the primary tumour resection, either using BHA (29) or THA (28), were included. Functional outcome was assessed using the Musculoskeletal Tumour Society (MSTS) scoring system and Harris Hip Score (HHS). Postoperative complications of the two techniques were also compared.Aims
Methods
Rarely, the extent of a malignant bone tumour
may necessitate resection of the complete humerus to achieve adequate
oncological clearance. We present our experience with reconstruction
in such cases using a total humeral endoprosthesis (THER) in 20
patients (12 male and eight female) with a mean age of 22 years
(6 to 59). We assessed the complications, the oncological and functional
outcomes and implant survival. Surgery was performed between June
2001 and October 2009. The diagnosis included osteosarcoma in nine,
Ewing’s sarcoma in eight and chondrosarcoma in three. One patient
was lost to follow-up. The mean follow-up was 41 months (10 to 120)
for all patients and 56 months (25 to 120) in survivors. There were
five local recurrences (26.3%) and 11 patients were alive at time
of last follow-up, with overall survival for all patients being
52% (95% confidence interval (CI) 23.8 to 74) at five years. The
mean Musculoskeletal Tumor Society score for the survivors was 22
(73%; 16 to 23). The implant survival was 95% (95% CI 69.5 to 99.3)
at five years. The use of a THER in the treatment of malignant tumours of bone
is oncologically safe; it gives consistent and predictable results
with low rates of complication.

Over a 16-year period, 135 custom-made distal femoral prostheses, based on a fully constrained Stanmore-type knee replacement, were used in the treatment of primary malignant or aggressive benign tumours. Survivorship analysis showed a cumulative success rate of 72% at five years and 64% at seven years. Intact prostheses in 91% of the surviving patients gave good or excellent functional results. Deep infection was the major complication, occurring in 6.8% of cases; clinical aseptic loosening occurred in 6.0%. Revision surgery was carried out for loosening and infection, and the early results are encouraging. We conclude that prosthetic replacement of the distal femur can meet the objectives of limb salvage surgery.
Aims. Proximal femoral endoprosthetic replacements (PFEPRs) are the most common reconstruction option for osseous defects following primary and metastatic tumour resection. This study aimed to compare the rate of implant failure between PFEPRs with monopolar and bipolar hemiarthroplasties and acetabular arthroplasties, and determine the optimum articulation for revision PFEPRs. Methods. This is a retrospective review of 233 patients who underwent PFEPR. The mean age was 54.7 years (SD 18.2), and 99 (42.5%) were male. There were 90 patients with
En-bloc resection, extracorporeal irradiation and re-implantation of the irradiated bone have been used to treat 15 patients suffering from primary malignant tumours of bone or cartilage and two with benign lesions. This treatment is an alternative to replacement by prosthesis or allograft bridging techniques. After a mean follow-up of over five years results are encouraging, despite some complications and the relatively long period before weight-bearing is allowed.
Aims. Resection of the proximal humerus for the primary malignant bone
tumour sometimes requires en bloc resection of the
deltoid. However, there is no information in the literature which
helps a surgeon decide whether to preserve the deltoid or not. The
aim of this study was to determine whether retaining the deltoid
at the time of resection would increase the rate of local recurrence.
We also sought to identify the variables that persuade expert surgeons
to choose a deltoid sparing rather than deltoid resecting procedure. Patients and Methods. We reviewed 45 patients who had undergone resection of a primary
malignant tumour of the proximal humerus. There were 29 in the deltoid
sparing group and 16 in the deltoid resecting group. Imaging studies
were reviewed to assess tumour extension and soft-tissue involvement.
The presence of a fat rim separating the tumour from the deltoid
on MRI was particularly noted. The cumulative probability of local
recurrence was calculated in a competing risk scenario. Results. There was no significant difference (adjusted p = 0.89) in the
cumulative probability of local recurrence between the deltoid sparing
(7%, 95% confidence interval (CI) 1 to 20) and the deltoid resecting
group (26%, 95% CI 8 to 50). Patients were more likely to be selected
for a deltoid sparing procedure if they presented with a small tumour
(p = 0.0064) with less bone involvement (p = 0.032) and a continuous
fat rim on MRI (p = 0.002) and if the axillary nerve could be identified
(p = 0.037). Conclusion. A deltoid sparing procedure can provide good local control after
resection of the proximal humerus for a

Due to its indolent clinical behaviour, the treatment paradigm of atypical cartilaginous tumours (ACTs) in the long bones is slowly shifting from intralesional resection (curettage) and local adjuvants, towards active surveillance through wait-and-scan follow-up. In this retrospective cohort study performed in a tertiary referral centre, we studied the natural behaviour of ACT lesions by active surveillance with MRI. Clinical symptoms were not considered in the surveillance programme. The aim of this study was to see whether active surveillance is safe regarding malignant degeneration and local progression. In total, 117 patients were evaluated with MRI assessing growth, cortical destruction, endosteal scalloping, periosteal reaction, relation to the cortex, and perilesional bone marrow oedema. Patients received up to six follow-up scans.Aims
Methods
The purpose of this study was to evaluate the functional and oncological outcome of recycled autograft reconstruction after a wide excision for primary malignant bone tumor around the hip. From 1998 to 2015, 67 patients with a primary malignant bone tumor involving proximal femur or periacetabular zone (P2) were included. There were 36 males and 31 females with a mean age of 34 years (13 to 58). Of these, 29 patients had grade I or II chondrosarcoma, 28 high-grade osteosarcoma, 6 Ewing's sarcoma and 4 undifferentiated pleomorphic sarcoma. Enneking stage of all 67 patients was stage II. Of the resection classification, proximal femur resection was performed in 29 patients, P1+P2 in 15, P2+P3 in 14, P1+P2+P3 in 4, P2 only in 4, and P2+proximal femur in 1. Extracorporeally irradiated recycled autograft and liquid nitrogen frozen autograft were performed in 44 and 23 patients, respectively. At a mean follow-up of 98 months (10 to 239), 48 patients (72%) were continuously disease-free, 12 (18%) died of disease and 7 (10%) were alive with disease. The tumors of these patients who had died of disease were usually located in pelvic bones (10/12). Of these 37 patients with pelvic tumors, 7 patients (22%) had local recurrence, four of them received external hemipelvectomy. Other complications included hip dislocation in 2 patients, nerve injury in 2 and deep infection in 2. However, the above complications were rarely occurred in the patients with proximal femur reconstruction. The mean Musculoskeletal Tumor Society functional score were 77% (53 to 93). Recycled autograft reconstruction for primary malignant bone tumor around the hip is a valid method with acceptable morbidity and a favorable functional outcome.

Introduction. Aseptic loosening is the most common mode of failure of massive endoprostheses. Introduction of Hydroxyapatite coated collars have reduced the incidence of aseptic loosening. However bone growth is not always seen on these collars. Objectives. The aims of our study were to determine the extent of osseous integration of Hydroxyapatite coated collars, attempt a grading system for bone growth and to determine the effect of diagnosis, surgical technique and adjuvant therapy on bone growth. Methods. We reviewed the records and radiographs of 58 patients who had a massive endoprosthesis implanted by two surgeons in our unit over the last five years. Revision surgeries were recorded separately. Bone growth was graded 1–4 based on appearance in antero-posterior and lateral radiographs. Results. Three groups were identified. Group 1-Resections for

Endoprosthetic replacement of the pelvis is one of the most challenging types of limb-salvage surgery, with a high rate of complications. In an attempt to reduce this and build greater versatility into the reconstruction process, a new type of pelvic endoprosthesis was developed in 2003, based on the old McKee-Farrar prosthesis. This study reviews the outcomes in 27 patients who had an ice-cream cone pelvic prosthesis inserted at two different specialist bone tumour centres in the United Kingdom over the past six years.
