Introduction: The conventional approach to spinal malignancy is via intralesional piecemeal resection but the incidence of local recurrence after surgery has been increasing as survival of patients getting prolonged due to advance adjuvant treatment TES is devised to minimize the incidence of local recurrence in malignant spinal tumours. The purpose of this study is to analyse whether the radical procedure like TES is justifiable in solitary metastasis or not. Material & Methods: We analysed 6 patients who undergone surgery for metastases of spine secondary to renal cell carcinoma between1996 and 2005 out of which 4 had TES for solitary intraosseous thoracolumbar lesion. They include three men and one woman ranging an age from 51 to 64 years. Common presenting complaints were intractable back pain dependent on opiates and progressive neural deficit. Four patients had localised intraosseous thoraco-lumbar lesion. The extent of spinal lesion was assessed with X-rays, CT scans and MRI for all patients. All patient’s prognosis was analysed by Tokuhasi Scoring System.3 patients had pre-op embolisation.4 patients with solitary intra-osseous metastasis underwent radical surgery in the form of total vertebrectomy and 3- column stabilisation of spine. Total surgical time was between 9–13 hrs and total blood loss between 4–11 Litres. Results: None of the patients had surgery related major complication. No external brace used for mobilisation. The surgical outcome assessed by the pain, severity of paresis and the ability to walk before and after surgery. All patients followed up regularly to detect local tumour recurrences and position of implant. None of the patients with TES shown signs of local recurrence The follow up period for the surviving patients ranged from 9 to 32 months after TES. One patient died 9 month post-op due to widespread metastasis. Conclusion: TES offers the most aggressive mode of treatment for the solitary metastasis of Thoraco-Lumbar spine secondary to Renal Cell Carcinoma. Considering the technical demands and potential risks of TES, the indication for TES with spinal metastasis should be limited to the cases with solitary intra-osseous lesions in malignancies with good prognosis

Abstract. Objectives. To determine the effects of self-management interventions (SMIs) including an exercise component (EC) on low back pain (LBP) and disability and to determine whether SMIs with tailored exercises (TEs) have superior outcomes compared to SMIs with general exercises (GEs). Methods. An electronic systematic search of randomized controlled trials (RCTs) was performed in 5 electronic databases. RCTs compared SMIs with an EC to control interventions. Data were extracted at 3 follow-up points (short-term, intermediate and long-term) and meta-analyses were performed. Reviewed RCTs were divided into subgroups based on whether the EC was tailored or generic. A subgroup meta-analysis was performed at the short-term follow-up to assess whether the SMIs with TEs have superior outcomes compared to SMIs with GEs. Results. 12 original RCTs were included in the review (six including SMIs with TEs) and were of moderate quality. The pooled results revealed the effect sizes (ESs) of −0.26,-0.32 and −0.21 for short, intermediate and long-term pain intensity, respectively and −0.26,-0.22 and −0.21 for short, intermediate, and long-term disability, respectively (negative value indicates a mean difference in favour of SMIs) indicating a moderate but significant reduction in pain and disability compared to controls. Subgroup meta-analysis at the short-term follow-up revealed that SMIs with TEs had ES of –0.19(p=0.004) for pain and –0.20(p=0.002) for disability compared to SMIs with GEs demonstrating positive but not significant improvement in pain (ES −0.48, p=0.09) and disability (ES −0.45, p=0.10). Conclusions. There is moderate quality evidence for SMIs with an EC to have moderate but significant positive effect on pain and disability in people with LBP. The subgroup analysis revealed that SMIs with exercises tailored to person's needs are superior in reducing pain and disability. These results indicate the importance of developing TE solutions supporting self-management to improve its effect on pain and disability in LBP patients. Declaration of Interest.

Introduction: Total en bloc spondylectomy (TES) as the only radical treatment option for sarcoma and solitary metastases of the spine was shown to markedly minimize local recurrences, improve patient quality of life and substantially increase overall survival rates. Due to surgical difficulty of TES and complex biomechanical demands in defect reconstruction multisegmental tumor involvement of the spine has long been considered as a palliative situation, exceeding the limits of surgical feasibility. Thus, multilevel resections reports are very rare. For the first time, this study analyzes the onco-surgical results after multilevel thoracolumbar TES and reconstruction with a carbon composite vertebral body replacement system (CC-VBR) in a collective of patients. Methods: 18 patients (9f/9m; age 52±14y) treated with thoracolumbar multilevel TES (6x2, 9x3, 3x4 segments) for spinal sarcomas (n=9), solitary metastases (n=5) and aggressive primary tumors (n=3) were retrospectively investigated. According to the classification system of Tomita et al. all patients were surgically staged as type 6 (multisegmental/extracompartimental). Defect reconstruction (11 thoracic, 3 thoracolumbar and 4 lumbar) were performed with posterior stabilization and a CC-VBR. Patient charts and the current clinical follow-up results were analyzed for histopathological tumor type, pre- and postoperative data (symptoms, duration of surgery, blood loss, complications, intensive care, adjuvant therapies etc.) and course of disease. Latest radiographs and CT-scans were analyzed at follow up. Oncological status was evaluated using cumulative disease specific and metastases-free survival analysis. Results: With a mean follow up (100%) of 18 (4–44) months 17 patients (94%) were postoperatively ambulatory without any support. Postoperative neurological deficits were seen in one patient (6%). Wide resection margins were attained in 7, marginal in 11 patients. Depending on tumor biology/grading and/or resections margins an adjuvant therapy (radiation/chemotherapy) was performed in 12 (67%) patients. Local recurrence was found in one patient (6%). 13 (72%) patients showed no evidence of disease, 3 were alive with disease while 2 died of disease at 10 and 27 months postoperatively. Conclusion: In selected patients with multisegmental spinal tumor involvement oncological sufficient resections can be reached by multilevel TES. Although the surgical procedure is challenging and the patient’s stress is considerable our encouraging midterm results together with the low complication rate clearly favour and legitimate this technique. However, treatment success strongly depends on adjuvant therapies. Reconstruction with a CC-VBR showed low complication rates, promising biomechanical characteristics, increased volume for bone grafting and lower artefact rates in follow-up MR- and CT-imaging

To compare outcomes and costs of transforaminal endoscopic surgical discectomy (TES) with those of microdiscectomy (Micro). 48 patients with a primary lumbar disc prolapse were randomly allocated by computer to surgery. Assessments were made of leg and back pain (VAS), Oswestry Disability index (ODI), and SF-36 as primary outcomes. Cost data was collated. 25 TES and 23 Micro patients are reported with similar age, sex, smoking status and affected disc levels (14 v.17 L5/S1). Three months following surgery leg pain scores had decreased by 55 and 65% in the two groups. Patient satisfaction ratings were equal. ODI had decreased 15 points in both groups by 1yr and this improvement was maintained to 2 years (final scores: 7±3 TES v.14±13 Micro - means ±SD; p<0.05). Similar changes were noted in SF36-P. Mean bed stay was lower in the TES group (16 v. 40 hours). Other post-operative costs were similar. There were no immediate complications. One revision was required at 12 months (TES) and one at 18 months (Micro). Two patients presented with a disc prolapse at a different level and side (both TES). Results at up to two years follow-up are similar following the two interventions. Recovery was more rapid in those patients undergoing endoscopic surgery

Introduction. Tomita En-bloc spondylectomy (TES) of L5 is one of the most challenging spinal surgical techniques. A 42-year-old female was referred with low back pain and L5 radiculopathy with background of right shoulder excision of liposarcoma. CT-PET confirmed a solitary L5 oligometastasis. MRI showed thecal sac indentation and therefore was not suitable for stereotactic ablative radiotherapy (SABR) alone. Planning Methodology. First Stage: Carbon fibre pedicle screws were planned from L2 to S2AI-Pelvis, aligned to her patient-specific rods. Custom 3D-printed navigation guides were used to overcome challenging limitations of carbon instruments. Radiofrequency ablation (RFA) of L5 pedicles prior to osteotomy was performed to prevent sarcoma cell seeding. Microscope-assisted thecal sac-tumour separation and L5 nerve root dissection was performed. Novel surgical navigation of the ultrasonic bone cutter assisted inferior L4 and superior S1 endplate osteotomies. Second stage: We performed a vascular-assisted retroperitoneal approach to L4-S1 with protection of the great vessels. Completion of osteotomies at L4 and S1 to en-bloc L5: (L4 inferior endplate, L4/5 disc, L5 body, L5/S1 disc and S1 superior endplate). Anterior reconstruction used an expandable PEEK cage obviating the need for a third posterior stage. Reinforced with a patient-specific carbon plate L4-S1 promontory. Sacrifice of left L5 nerve root undertaken. Results. Patient rehabilitated well and was discharged after 42 days. Patient underwent SABR two months post-operatively. Despite left foot drop, she was walking independently 9 months post-operatively. Conclusion. These challenging cases require a truly multi-disciplinary team approach. We share this technique for a dual stage TES and metal-free construct with post adjuvant SABR for maximum local control

Introduction: Patients with solitary spinal metastases from Renal Cell Carcinoma (RCC) have better prognosis and show longer survival rates compared to other spinal metastatic disease. Adjuvant control by chemotherapy and hormonal therapy has been proven ineffective to treat this relatively radio resistant tumour, which can often present with both back pain and neurological deficit. Selected patients can be treated with Total En bloc Spondylectomy (TES) for solitary intra-osseous metastasis in the thoracolumbar spine secondary to renal cell carcinoma. Methods: Four patients with solitary vertebral metastasis secondary to RCC underwent TES for radical resection of the spinal pathology after pre-operative embolisation. The procedure involves en bloc laminectomy and corpectomy with posterior instrumented fusion and anterior instrumentation with cage reconstruction following the spondylectomy. All patients were fully staged pre-operatively and assessed according to the Tokuhashi scoring system to determine predictive life expectancy. Results: All patients demonstrated full neurological recovery and reported significant pain relief. One patient died at 11 months post-op due to a recurrence of the primary in the nephrectomy bed. The other three are alive and well at 33, 40 and 54 months post-op with no radiological evidence of tumour recurrence in the spine. There were no major surgical complications. Discussion: Careful patient selection is required to justify this procedure. The indication is best limited to solitary intra-osseous lesions where complete resection of the tumour is possible. The main advantage of this treatment is that it affords significant pain relief and restores spinal stability whilst minimizing local recurrence. Conclusion: TES can improve symptomatic control of isolated solitary spinal metastases of the thoracolumbar spine in Renal Cell Carcinoma

Purpose: The purpose of this study was to evaluate the results of custom-made endoprosthetic reconstruction for both tumourous and non-tumourous conditions around the elbow joint. Methods and Results: 28 consecutive cases of endoprosthetic elbow reconstruction, performed between 1989 and 2003, were identified using the unit database. There were 12 males and 16 females, with a mean age of 48.9 years, (range 14–84). There were 16 cases of malignant tumour (10 primary, 6 secondary), 3 cases of benign tumour (one each of giant cell tumour, osteoblastoma and pigmented villonodular synovitis) and 10 non-oncological cases, (5 cases of fracture, 3 failed total elbow replacements and 1 infected synostosis). A distal humeral prosthesis was used in 16 patients, distal humeral and proximal ulna in 10 patients, proximal ulna with a humeral component in one patient and proximal radial replacement in one patient. Clinical and radiographic review of all available patients, including a functional assessment with The Toronto Extremity Salvage (TES) score was undertaken. The average follow-up was 54.9 months (range 5–144). 5 patients with malignancy died of their disease. One patient required amputation for local recurrence at 5 months. There were two revisions at 4 and 7 years for aseptic loosening of the humeral component. Six patients developed deep prosthetic infection at an average of 21 months (range 6–31), necessitating two-stage revision, of which one patient required subsequent excision arthroplasty. There were no cases of permanent nerve palsy. 18 patients (64.3%) were available for functional follow-up. Average flexion deformity was 33 degrees (7–80) and average flexion was 85 degrees (30–133). The mean TES score was 67.8 (range 36.6–96.6). The mean TES score following two-stage revision for infection, (available in 4/5 patients) was 73.9 (range 54.8–91.6). Conclusion: Custom-made endoprosthetic reconstruction around the elbow joint is effective in a wide range of pathologies, allowing in most cases a reasonable level of function, even following two-stage revision for infection

Patients with solitary spinal metastases from Renal Cell Carcinoma (RCC) have better prognosis and survival rates compared to other spinal metastatic disease. Adjuvant therapy has been proven ineffective. Selected patients can be treated with Total En bloc Spondylectomy (TES) for solitary intra-osseous metastasis in the thoracolumbar spine secondary to renal cell carcinoma. Five patients with solitary vertebral metastasis secondary to RCC underwent TES for radical resection of the spinal pathology after pre-operative embolisation. The procedure involves en bloc laminectomy and corpectomy with posterior instrumented fusion and anterior instrumentation with cage reconstruction following the spondylectomy. All patients were fully staged pre-operatively and assessed according to the Tokuhashi scoring system. Recurrence of spinal metastasis and radiological failure of reconstruction. All patients demonstrated full neurological recovery and reported significant pain relief. One patient died at 11 months post-op due to a recurrence of the primary. The other four are well at 24, 45, 52 and 66 months post-op without evidence of recurrence in the spine. There were no major surgical complications. Careful patient selection is required to justify this procedure. The indication is limited to solitary intra-osseous lesions where complete resection of the tumour is possible. The main advantage of this treatment is that it affords significant pain relief and restores spinal stability whilst minimizing local recurrence

The distal humerus represents 1% of all primary bone tumours. Endoprosthetic replacement can potentially improve function and provide good pain relief. We present out experience with the custom made Stanmore elbow endoprosthesis used after resection of malignant tumours of the distal humerus. Between 1970–2009 we carried out 19 endoprosthetic replacments for malignant tumours of the distal humerus. 10 were a result of metastasis and 9 were primary bone tumours. 7 patients had a pathological fracture as their first presentation and 3 had pathological fractures after the diagnosis was made. 11 patients died between 3 months to 16 year following surgery. The mean survival of the patient group was 7.1 years (range 3 months to 37 years). 4 patients underwent a revision EPR and one patient underwent two revision EPR's due to loosening. Two patients underwent maintenance procedures (rebushing) due to wear of the poly bushing. We have had no revisions since the design of hte implant was changed to a floppy hinge design. One patient underwent an above elbow amputation four years after surgery due to local recurrence. There were no early post operative infections. One patient developed a sinus requiring multiple wound explorations, one year after insertion of the endoprosthesis for a sarcoma. This patient was infection free till the time of death 3 years later. There were no nerve palsies, periprosthetic fractures or wound problems. The mean TES score was 72% (59–78%) in the surviving patients at review. As the majority of the patients were implanted for metastatic disease the initial reliablity and low complication rate of the procedure, in our series, confirms that this is a suitable reconstruction for patients in significant metastatic pain from a destructive lesion of the distal humerus, rapidly restoring function and relieving pain in a predictable manner

Endoprosthetic reconstruction as a form of limb salvage in the management of malignant disease is common. We present our experience with custom-made distal femoral replacement as a form of limb salvage in the absence of malignancy. 49 cases of distal femoral replacement were identified using the unit database. There were 18 males and 31 females, with a mean age at operation of 62.3 years (range 26–86). There were 29 cases of failed total knee replacements, 8 cases of fracture associated with bone loss, non-union or deformity, 7 periprosthetic fractures, 3 aneurysmal bone cysts, and one case each of avascular necrosis and Gorham’s disease. Clinical and radiographic review of all available patients, including a functional assessment with the Musculoskeletal Tumour Society (MSTS) Score and Toronto Extremity Salvage (TES) score was undertaken. The average follow-up was 5.4 years (range 1 to 29 years). Three types of endoprosthesis were used, rotating hinge, fixed hinge and arthrodesis prosthesis. One patient required amputation at 2 months following post-operative wound infection with methicillin-resistant staphylococcus aureus and subsequent inability to provide adequate soft tissue coverage. There was one revision at 16 months for deep prosthetic infection. 21 patients were available for functional follow-up. The mean MSTS score was 63.7 (range 16.0–86.7) and the mean TES score was 59.4 (range 9.4–87.5). Custom-made distal femoral replacements have an established role in limb-salvage surgery for malignant disease. This series demonstrates the reconstructive capability of custom prostheses in non-malignant disease, where deformity causes functional embarrassment or when massive bone loss would normally lead to amputation

Study Design: Descriptive case series. Objective: To report on the outcome of 4 patients treated with Total En bloc Spondylectomy (TES) for solitary intra-osseous metastasis in the thoracolumbar spine secondary to hypernephroma. Summary of background data: Patients with solitary spinal metastases from renal cell carcinoma (RCC) have better prognosis and show longer survival rates as compared to other spinal metastatic disease. Adjuvant control by chemotherapy and hormonal therapy has been proven ineffective to treat this relatively radioresistant tumour, which can often present with both back pain and neurological deficit. Methods: Four patients with solitary vertebral metastasis secondary to RCC underwent TES for radical resection of the spinal pathology. The procedure involves en bloc laminectomy and corpectomy with posterior instrumented fusion and anterior instrumentation with cage reconstruction following the spondylectomy. All patients were fully staged pre-operatively and assessed according to the Tokuhashi scoring system to determine predictive life expectancy. 3 of the 4 had pre-operative embolization and all had radical resection of the primary tumour. Results: All patients reported significant pain relief and demonstrated neurological improvement. One patient died at 11 months post-op due to a recurrence of the primary in the nephrectomy bed. 3 were alive and well at 18, 26 and 39 months post-op with no radiological evidence of tumour recurrence. There were no major surgical complications. Conclusions: Careful patient selection is required to justify this procedure. The indication is best limited to solitary intra-osseous lesions where complete resection of the tumour is possible. The main advantage of this treatment is that it affords significant pain relief and restores spinal stability whilst minimizing local recurrence

Only 1% of all primary bone tumours are situated in the distal humerus. Destruction of the distal humerus by tumour is rare and reconstruction of the distal humerus is challenging. Because of the amount of bone loss following tumour excision, excision arthroplasty or arthrodesis is impossible and hence some form of reconstruction is usually required. Allograft reconstruction and hemiarthroplasty are uncommon and lead to an unpredictable outcome. Ten patients underwent endoprosthetic replacement of the distal humerus for bone tumours over a thirty one-year period. There were 8 primary and 2 secondary tumours and male to female ratio was 2:3. Average age of the patients was 47.5 years (15–76 years). Mean follow up was 8 years (9 months - 31 years). Four patients required further surgery, three having revision for asceptic loosening and two of these and one other later needing a rebushing. There were no permanent nerve palsies, infections, local recurrences or mechanical failures of the implant. Four patients died of their disease between 12 and 71 months after operation, all with their prosthesis working normally. Average flexion deformity was 15 degrees (0–35) and average flexion of these patients was 115 degrees (110–135). The average TES Score for these patients was 73% (29% to 93%). The activities which the patients found to be no problem (TES score more than 4.5 out of 5) were: brushing hair, drinking from a glass, putting on make up or shaving, picking up small items, turning a key in a lock, doing light household chores and socialising with friends, whilst activities that proved difficult (TES score less than 3 out of 5) were: gardening and lifting a box to an overhead shelf. Pain was not a problem and only 1 of the surviving patients reported ever having to use regular analgesics. Conclusions: Endoprosthetic replacement of the distal humerus and elbow joint is a satisfactory method of dealing with these unusual tumours in the long term
