Several techniques have been described to reconstruct a mobile wrist joint after resection of the distal radius for tumour. We reviewed our experience of using an osteo-articular allograft to do this in 17 patients with a mean follow-up of 58.9 months (28 to 119). The mean range of movement at the wrist was 56° flexion, 58° extension, 84° supination and 80° pronation. The mean ISOLS-MSTS score was 86% (63% to 97%) and the mean patient-rated wrist evaluation score was 16.5 (3 to 34). There was no local recurrence or distant metastases. The procedure failed in one patient with a fracture of the graft and an arthrodesis was finally required. Union was achieved at the host-graft interface in all except two cases. No patient reported more than modest non-disabling pain and six reported no pain at all. Radiographs showed early degenerative changes at the radiocarpal joint in every patient. A functional pain-free wrist can be restored with an osteo-articular allograft after resection of the distal radius for bone tumour, thereby avoiding the donor site morbidity associated with an autograft. These results may deteriorate with time

Introduction. Primary bone tumours of the distal radius are rare, while it remains the third commonest site for primary lesions and recurrences of Giant Cell Tumours (GCT). The functional demands on the hand make reconstruction of the wrist joint following the excision of distal radius, particularly challenging. Methods. A single-centre retrospective study, reporting the functional and oncological outcomes of six patients (4 males, 2 females - mean age of 53 (22 to 79)) who underwent a custom-made endoprosthetic replacement of the distal radius with arthrodesis at our institution, during 1999 - 2010. Five patients were diagnosed with primary bone sarcoma of the distal radius (4 GCTs, 1 osteosarcoma) and another had a metastatic lesion from a primary renal cell carcinoma. The diagnosis was confirmed by needle biopsy in all cases. We assessed the patients' functional outcomes using the Musculoskeletal Tumour Society scoring system (MSTS) and the Toronto Extremity Salvage Score (TESS). Results. The mean follow-up was 3 years (up to 9.5 years). One patient died of unrelated medical causes, age 89, and one patient succumbed to renal carcinoma, age 53 (9.5 and 4 years post-operatively). All prostheses remained clinically and radiologically stable. One-year radiographs confirmed bone remodelling and osseointegration at the bone-prosthesis interface. There were no cases of local recurrence, metastases, infection or wound complications post-operatively. The mean functional outcome scores were: MSTS 73% (71 to 78), TESS 75% (73 to 79). Pain-free hand movements were restored in all cases. Discussion. Reconstruction options include curettage with/without grafting or cementing, ulna translocation, autografts (vascularised or non-vascularised ⊞/⊟ arthrodesis), allografts, custom-made megaprostheses. Custom-made endoprosthetic reconstruction of the distal radius with wrist arthrodesis following bone tumour resection represents a viable and versatile treatment option. Satisfactory outcomes are achieved with acceptable risks and functional outcomes; especially when considering the nature of the diagnosis and alternative treatment options

Between June 2005 and March 2008, 14 patients with a Campanacci grade-3 giant-cell tumour of the distal radius were treated by en bloc resection and reconstruction by ulnar translocation with arthrodesis of the wrist. The mean length of radius resected was 7.9 cm (5.5 to 15). All the patients were followed to bony union and 12 were available at a mean follow-up of 26 months (10 to 49). The mean time to union was four months (3 to 7) at the ulnocarpal junction and five months (3 to 8) at the ulnoradial junction. All except one patient had an excellent range of pronation and supination. The remaining patient developed a radio-ulnar synostosis. The mean Musculoskeletal Tumor Society score was 26 (87%, range 20 to 28). Three patients had a soft-tissue recurrence, but with no bony involvement. They underwent a further excision and are currently well and free from disease. Ulnar translocation provides a local vascularised bone graft to reconstruct the defect left after excision of the distal radius for giant cell tumour. It avoids the need for a microvascular procedure while retaining rotation of the forearm and good function of the hand

Aims. Giant cell tumour of bone (GCTB) is a locally aggressive lesion that is difficult to treat as salvaging the joint can be associated with a high rate of local recurrence (LR). We evaluated the risk factors for tumour relapse after treatment of a GCTB of the limbs. Methods. A total of 354 consecutive patients with a GCTB underwent joint salvage by curettage and reconstruction with bone graft and/or cement or en bloc resection. Patient, tumour, and treatment factors were analyzed for their impact on LR. Patients treated with denosumab were excluded. Results. There were 53 LRs (15%) at a mean 30.5 months (5 to 116). LR was higher after curettage (18.4%) than after resection (4.6%; p = 0.008). Neither pathological fracture (p = 0.240), Campanacci grade (p = 0.734), soft-tissue extension (p = 0.297), or tumour size (p = 0.872) affected the risk of recurrence. Joint salvage was possible in 74% of patients overall (262/354), and 98% after curettage alone (262/267). Of 49 patients with LR after curettage, 44 (90%) underwent repeated curettage and joint salvage. For patients treated by curettage, only age less than 30 years (p = 0.042) and location in the distal radius (p = 0.043) predicted higher LR. The rate of LR did not differ whether cement or bone graft was used (p = 0.753), but may have been reduced by the use of hydrogen peroxide (p = 0.069). Complications occurred in 15.3% of cases (54/354) and did not differ by treatment. Conclusion. Most patients with a GCTB can undergo successful joint salvage by aggressive curettage, even in the presence of a soft-tissue mass, pathological fracture, or a large lesion, with an 18.4% risk of local recurrence. However, 90% of local relapses after curettage can be treated by repeat joint salvage. Maximizing joint salvage is important to optimize long-term function since most patients with a GCTB are young adults. Younger patients and those with distal radius tumours treated with joint-sparing procedures have a higher rate of local relapse and may require more aggressive treatment and closer follow-up.

Aims. To assess complications and failure mechanisms of osteoarticular allograft reconstructions for primary bone tumours. Patients and Methods. We retrospectively evaluated 38 patients (28 men, 74%) who were treated at our institution with osteoarticular allograft reconstruction between 1989 and 2010. Median age was 19 years (interquartile range 14 to 32). Median follow-up was 19.5 years (95% confidence interval (CI) 13.0 to 26.1) when 26 patients (68%) were alive. In addition, we systematically searched the literature for clinical studies on osteoarticular allografts, finding 31 studies suitable for analysis. Results of papers that reported on one site exclusively were pooled for comparison. Results. A total of 20 patients (53%) experienced graft failure, including 15 due to mechanical complications (39%) and three (9%) due to infection. In the systematic review, 514 reconstructions were analysed (distal femur, n = 184, 36%; proximal tibia, n = 136, 26%; distal radius, n = 99, 19%; proximal humerus, n = 95, 18%). Overall rates of failure, fracture and infection were 27%, 20%, and 10% respectively. With the distal femur as the reference, fractures were more common in the humerus (odds ratio (OR) 4.1, 95% CI 2.2 to 7.7) and tibia (OR 2.2, 95% CI 1.3 to 4.4); infections occurred more often in the tibia (OR 2.2, 95% CI 1.3 to 4.4) and less often in the radius (OR 0.1, 95% CI 0.0 to 0.8). Conclusion. Osteoarticular allograft reconstructions are associated with high rates of mechanical complications. Although comparative studies with alternative techniques are scarce, the risk of mechanical failure in our opinion does not justify routine employment of osteoarticular allografts for reconstruction of large joints after tumour resection.

We reviewed 23 patients with a giant-cell tumour (GCT) of bone and histologically-proven lung metastases at a mean of 11.9 years (3 to 24.5) after the original diagnosis. The mean age of the patients at diagnosis was 27.3 years (9 to 61); the male to female ratio was 0.9:1. The most common primary site was the distal radius. The mean interval between the onset of the tumour and the detection of lung metastases was 4.1 years (0 to 24). There had been local recurrence in 19 (83%) either before or at the time of diagnosis of lung metastasis. Surgical resection alone was the preferred treatment for lung metastases in 70% and resulted in 18 patients (76%) being free from disease when last reviewed. One patient had the spontaneous regression of lung metastases and was free from recurrence 16 years later. Sixteen patients (69.7%) have survived and four (17.4%) have died from progression of the tumour. Three other deaths were not related to the tumour. Local recurrence and a primary lesion at the distal radius seem to be associated with an increased risk of lung metastases. Repeated surgical resection of lung metastases gave a high rate of survival

Aims

The aim of this study was to determine the rate of indocyanine green (ICG) staining of bone and soft-tissue tumours, as well as the stability and accuracy of ICG fluorescence imaging in detecting tumour residuals during surgery for bone and soft-tissue tumours.

Aims

Due to their radiolucency and favourable mechanical properties, carbon fibre nails may be a preferable alternative to titanium nails for oncology patients. We aim to compare the surgical characteristics and short-term results of patients who underwent intramedullary fixation with either a titanium or carbon fibre nail for pathological long-bone fracture.

Aim. Giant cell tumour (GCT) of bone is a benign but locally aggressive tumour. Although topical adjuvants have been used in the past, local recurrence following intralesional excision of GCT of bone continues to remain a problem. The use of bisphosphonates as an anti-osteoclastic agent in the management of osteolytic bone metastases is well accepted. Therefore our study aims to retrospectively demonstrate whether the administration of bisphosphonate as an adjuvant can control aggressive local recurrence of GCT and prevent wide resections of bones or amputations. Method. A retrospective study was performed between 2004 and 2010. 6 patients were diagnosed with aggressive local recurrence of appendicular GCT. All patients were treated for the primary tumour by surgical curettage and cryoablation followed by cementation or biological reconstruction. In 5 patients the tumour was located in the distal radius and in one in the first metacarpal bone. All recurrences were in the bone with large soft-tissue extension. After histological diagnosis – by CT core needle biopsy – the patients were treated by intravenous bisphosphonate, followed by clinical & radiological assessments. Results. Average follow-up of 42 months, ranging from 12 to 72 consecutive months. All patients showed good response to bisphosphonate treatment: lesions become calcified gradually as shown in x-rays & CT scans, reduction in size of soft tissue components, patient reported relief of pain & improvement of the affected limb. All treated patients did not report any untoward effects. Conclusion. In the current study bisphosphonate treatment is found to be an effective treatment for local control of aggressive local recurrence of GCT of the extremities and can therefore be a good alternative to wide resections of bone and complicated reconstructions. Functional results are shown to be promising as well. The study results need further investigation & a larger scale of patients

Introduction. Local recurrence of Giant cell tumours of bone (GCT) is considered the main complication of surgical treatment (50%). Intra-lesional curettage with adjuvants like phenol or polymethylmethacrylate (PMMA) is recommended as initial treatment, decreasing the risk of recurrence. However, risk factors for local recurrence in skeletal GCT have not yet been firmly established and a golden standard for treatment remains controversial. Aim of this study is identification of risk factors for recurrence in GCT, specifically after intra-lesional curettage with or without adjuvants. Methods. In a retrospective single-institution study 191 patients treated for GCT between 1964 and 2009 were included. Mean follow-up was 111 months (range 12-415). The recurrence-free survival and hazards for different treatment strategies and various patient and tumour characteristics were determined. Results. Overall risk of recurrence was 36.1% (n=66, 95% CI: 28.3-42.1). Recurrence rate after wide resection was 20%, after curettage with adjuvants 33% and after curettage alone 77%. Hogendoorn-grade III (Hazard Ratio: 5.7, p⋋0.001), localisation in axial skeleton (HR: 3.7, p⋋0,001), primary treatment in a non-specialised centre (HR: 2.8, p⋋0.001) and extension into soft tissue (HR: 2.0, p=0.02) were significant risk factors for local recurrence. Curettage with adjuvants proved superior to curettage alone (p⋋0.004 p=0.07, HR: 0.54), but the application of both PMMA and phenol did not present a significantly better outcome than PMMA alone (HR: 1.07, p=0.9). Discussion. Of all possible risk factors only soft tissue extension and localisation in distal radius significantly influenced the risk of local recurrence for all treatments. We found that high-grade tumours and localisation in the axial skeleton were additional risk factors for local recurrence after intra-lesional surgery. Although wide resection increases morbidity, it can be the therapy of choice in high risk patients. Intra-lesional therapy can be advised for low risk patients using curettage adjuvants and PMMA

Aims

Local recurrence remains a challenging and common problem following curettage and joint-sparing surgery for giant cell tumour of bone (GCTB). We previously reported a 15% local recurrence rate at a median follow-up of 30 months in 20 patients with high-risk GCTB treated with neoadjuvant Denosumab. The aim of this study was to determine if this initial favourable outcome following the use of Denosumab was maintained with longer follow-up.

Aims

The aims of this study were to evaluate the efficacy of preoperative denosumab in achieving prospectively decided intention of therapy in operable giant cell tumour of bone (GCTB) patients, and to document local recurrence-free survival (LRFS).

Aims

The aim of this paper was to investigate the prognostic factors for local recurrence in patients with pathological fracture through giant cell tumours of bone (GCTB).

Aims

The primary aim of this study was to determine the morbidity of a tibial strut autograft and characterize the rate of bony union following its use.

Aims

The aims of this study were to analyse the long-term outcome of vascularised fibular graft (VFG) reconstruction after tumour resection and to evaluate the usefulness of the method.

We conducted a case-control study to examine the merit of silver-coated tumour prostheses. We reviewed 85 patients with Agluna-treated (silver-coated) tumour implants treated between 2006 and 2011 and matched them with 85 control patients treated between 2001 and 2011 with identical, but uncoated, tumour prostheses.

In all, 106 men and 64 women with a mean age of 42.2 years (18.4 to 90.4) were included in the study. There were 50 primary reconstructions (29.4%); 79 one-stage revisions (46.5%) and 41 two-stage revisions for infection (24.1%).

The overall post-operative infection rate of the silver-coated group was 11.8% compared with 22.4% for the control group (p = 0.033, chi-square test). A total of seven of the ten infected prostheses in the silver-coated group were treated successfully with debridement, antibiotics, and implant retention compared with only six of the 19 patients (31.6%) in the control group (p = 0.048, chi-square test). Three patients in the silver-coated group (3.5%) and 13 controls (15.3%) had chronic periprosthetic infection (p = 0.009, chi-square test).

The overall success rates in controlling infection by two-stage revision in the silver-coated group was 85% (17/20) compared with 57.1% (12/21) in the control group (p = 0.05, chi-square test). The Agluna-treated endoprostheses were associated with a lower rate of early periprosthetic infection. These silver-treated implants were particularly useful in two-stage revisions for infection and in those patients with incidental positive cultures at the time of implantation of the prosthesis.

Debridement with antibiotic treatment and retention of the implant appeared to be more successful with silver-coated implants.

In patients with a tumour affecting the distal ulna it is difficult to preserve the function of the wrist following extensive local resection. We report the outcome of 12 patients (nine female, three male) who underwent excision of the distal ulna without local soft-tissue reconstruction. In six patients, an aggressive benign tumour was present and six had a malignant tumour. At a mean follow-up of 64 months (15 to 132) the mean Musculoskeletal Tumour score was 64% (40% to 93%) and the mean DASH score was 35 (10 to 80). The radiological appearances were satisfactory in most patients. Local recurrence occurred in one patient with benign disease and two with malignant disease. The functional outcome was thus satisfactory at a mean follow-up in excess of five years, with a relatively low rate of complications. The authors conclude that complex reconstructive soft-tissue procedures may not be needed in these patients.

We retrospectively studied local recurrence of giant cell tumour in long bones following treatment with curettage and cementing in 137 patients. The median follow-up time was 60 months (3 to 166). A total of 19 patients (14%) had at least one local recurrence, the first was diagnosed at a median of 17 months (3 to 29) after treatment of the primary tumour. There were 13 patients with a total of 15 local recurrences who were successfully treated by further curettage and cementing. Two patients with a second local recurrence were consequently treated twice. At the last follow-up, at a median of 53 months (3 to 128) after the most recent operation, all patients were free from disease and had good function.

We concluded that local recurrence of giant cell tumour after curettage and cementing in long bones can generally be successfully treated with further curettage and cementing, with only a minor risk of increased morbidity. This suggests that more extensive surgery for the primary tumour in an attempt to obtain wide margins is not the method of choice, since it leaves the patient with higher morbidity with no significant gain with respect to cure of the disease.
