To assess how effective are the prognostic scores and the role of delayed presentation in predicting the outcomes in patients with metastatic spine disease. Retrospectively data collected from December 2006 to December 2009. Medical records review included types of tumours, duration of symptoms, duration from referral to definitive treatment, expected survival, functional status before and after treatment. Karnofsky performance score and Modified Tokuhashi were used. Results: 50 patients underwent surgical stabilisation for metastatic spine disease with or with out cord compression. Age ranged from 39 to 87 years (Avg: 64). Patients had four main types of tumours; (Myeloma 30%, Lymphoma 22% Lung CA 16% and Renal 12 %). Inpatients without cord compression, the average time from referral to definitive treatment is 17 days. Over all fictional status improved in 70% of cases following surgical intervention. Patients who presented with cord compression had surgery with in 49 hours. Patients with high prognostic scores did not survive as long as expected. On the contrary, patients with poor prognostic scores survived longer than expected. This discrepancy is significant in patients with lung and renal malignancies. Patients with Myeloma did well as per the prognostic scores. Prognostic scores are not uniformly effective in all types of malignancies. Factors like delayed presentation and general condition were not included in the prognostic factors. Hence, we conclude that we cannot make a decision purely based on the prognostic scores to perform either palliative or definitive surgery

Introduction. Treatment of spinal metastatic disease has evolved with the advent of advanced interventional, surgical and radiation techniques. Spinal Oligometastatic disease is a low volume disease state where en bloc resection of the tumour, based on oncological principles, can achieve maximum local control (MLC). Hybrid therapy incorporating Separation surgery (>2mm clearance of the thecal sac) and Stereotactic Ablative Radiotherapy (SABR) offer an alternative approach to achieving MLC. Hybrid therapy is also a viable option in patients eligible for SBRT who have failed conventional radiation therapy. En-bloc surgery may be a suitable option for those patients who are ineligible for or have failed SBRT. A multidisciplinary approach is particularly important in the decision-making process for these patients. Metal free instrumentation is aiding the optimization of these surgeries. The authors present a supra-regional centre's experience in managing spinal oligometastases. Methods. Retrospective review of oligometastatic spinal disease at a supra-regional centre between 2017 and 2021. Demographics, operative course, complications and Instrument type are examined. Results. Demographics: 24 patients with mean age 53.8y (range 12–77), 44% (40y–59y), 40% (60y–69y); 51% Male. Histology: Breast, Renal and Sarcoma accounted for 16.7% each; Thyroid, Prostate and Chordoma accounted for 8.3% each. Primary disease 7%, Synchronous 15%, Metachronous 78%. Instrumentation: Carbon-fibre (85%), TiAl (11%), Non-Instrumented (3%). Separation Surgery (70%), En-bloc resection/Tomita surgery (30%); SABR/Proton Beam Planned: 70%. Average length of hospital stays 19.1 days; twenty patients required intensive care admission for an average 2.7 days. 30 Day Mortality 8.3% (n=2: COVID-19 during admission and ventriculitis post discharge), 1y Mortality – 16.7%, 3y Mortality – 25%; Synchronous Mortality 75% (n=3) at 3 years. 30 Day infection rate 3%; 1y infection rate 7%. 1 Non-instrumented case developed proximal junctional failure post proton beam therapy and required a vascularised fibular strut graft. 2-year Revision for Local Recurrence 5% (Revision at 23 months). Conclusion. There are very few case series of oligometastatic spinal disease due to the relatively new concept of adjuvant SABR and its limited availability. Solid tumours pre-dominated the histology in our series with metachronous disease being the most commonly operated disease state. 92% of cases were eligible for SABR. The majority (85%) of cases were performed with Carbon-fibre instrumentation and has been shown to be safe with no mechanical failures in this series. Infection rates are in keeping with patients requiring radical radiotherapy with 3% early and 7% late. 30-day mortality was 8.3%, 1y=16.7% and 25% at last follow up. Mortality, as expected, is highest within the synchronous disease group and should be operated on sparingly. With the current management strategy, there was no local recurrence at 1 year and excellent local recurrence rate at 2 years (5%). Although radical en bloc surgery carries significant morbidity, it should be considered in selective cases to achieve MLC. All Oligometastatic cases deserve extra consideration and specialist MDT as not all are suitable for SABR. Multimodal Hybrid therapy, incorporating less invasive surgical techniques and SABR, represents a paradigm shift in achieving MLC in oligometastatic spinal disease

Aims

Patients with differentiated thyroid carcinomas (DTCs) have a favourable long-term survival. Spinal metastases (SMs) cause a decline in performance status (PS), directly affecting mortality and indirectly preventing the use of systemic therapies. Metastasectomy is indicated, if feasible, as it yields the best local tumour control. Our study aimed to examine the long-term clinical outcomes of metastasectomy for SMs of thyroid carcinomas.

Methods

We collected data on 22 patients with DTC (16 follicular and six papillary carcinomas) and one patient with medullary carcinoma who underwent complete surgical resection of SMs at our institution between July 1992 and July 2017, with a minimum postoperative follow-up of five years. The cancer-specific survival (CSS) from the first spinal metastasectomy to death or the last follow-up was determined using Kaplan-Meier analysis. Potential factors associated with survival were evaluated using the log-rank test. We analyzed the clinical parameters and outcome data, including pre- and postoperative disability (Eastern Cooperative Oncology Group PS 3), lung and non-spinal bone metastases, and history of radioiodine and kinase inhibitor therapies.

Aim. To assess the safety of Zero Profile Interbody fusion (Zero P) device in Anterior Cervical Decompression and fusion (ACDF) for degenerative cervical stenosis. Method. 89 consecutive patients treated with Zero P interbody device from September 2009 to September 2012 were included in this retrospective study. Inclusion criterion: degenerative cervical stenosis with myelopathy, persistent radiculopathy after at least 3 months of failed conservative management. Exclusion criterion: Paediatric population; patients with infection, metastatic disease and trauma. There were 39 females, 50 males with mean age of 55 (ranging from 24 to 84 years). 56 (64%) had surgery at 1 level, 31 (35%) at 2 levels, 1 (1%) at 3 levels. Total number of levels operated were 121. Common levels operated were C56 (62%) and C67 (47%). Majority were operated due to radicular symptoms, 56 (64%) had radicular symptoms, 28(31%) had myelopathy and 5 (5%) Myeloradiculopathy. Results. All had a minimum of 6 months follow up (maximum 2 years). No patient had cage subsidence or extrusion. 1 had superficial infection which settled with antibiotics, 10 (11%) had dysphagia which settled in 6 to12 weeks. Conclusions. Our study demonstrates that ACDF with Zero P can be considered a safe option in management of patients with cervical degenerative stenosis. We would will also recommend a prospective randomised study as a follow on to this retrospective study. Preoperative kyphosis or lordosis did not change the outcome or make the surgical technique any more difficult, hence this implant can also be used in these circumstances. Conflicts of interest: No conflicts of interest. Sources of funding: No funding obtained

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

Aims

People with severe, persistent low back pain (LBP) may be offered lumbar spine fusion surgery if they have had insufficient benefit from recommended non-surgical treatments. However, National Institute for Health and Care Excellence (NICE) 2016 guidelines recommended not offering spinal fusion surgery for adults with LBP, except as part of a randomized clinical trial. This survey aims to describe UK clinicians’ views about the suitability of patients for such a future trial, along with their views regarding equipoise for randomizing patients in a future clinical trial comparing lumbar spine fusion surgery to best conservative care (BCC; the FORENSIC-UK trial).

Methods

An online cross-sectional survey was piloted by the multidisciplinary research team, then shared with clinical professional groups in the UK who are involved in the management of adults with severe, persistent LBP. The survey had seven sections that covered the demographic details of the clinician, five hypothetical case vignettes of patients with varying presentations, a series of questions regarding the preferred management, and whether or not each clinician would be willing to recruit the example patients into future clinical trials.

A prospective study was performed to evaluate the efficacy and safety of percutaneous kyphoplasty in patients with osteolytic tumours of thoracic and lumbar spine. To our knowledge this is the only study so far that has followed a cohort of patients prospectively until death. Prospective study of patients with lytic tumours of spine treated with kyphoplasty. A total of 13 patients with osteolytic tumours of spine were treated with kyhpoplasty. There were 8 female and 5 male patients. The age range was 52-81 years with average age of 65 years. A total of 25 vertebrae, from T2 to L3, were treated. The types of tumours included; non-Hodgkin lymphoma (2), myeloma (2), gastric-carcinoma (1), cervix-carcinoma (1), breast-carcinoma (3), prostate-carcinoma (2), small cell lung-carcinoma (1), bladder-carcinoma (1). Outcome was assessed prospectively by visual analogue scale (VAS) for pain, ECOG performance status, walking distance, standing and sitting time. The preoperative average VAS was 7.5 (range: 2.6 – 10). This dropped to 3.0 five days postoperatively and remained below 5 for the duration of follow-up. Average walking distance, standing and sitting time and ECOG performance score showed improvement. The survival time ranged from 2 to 293 weeks. The average survival time was 82 weeks. All patients were able to return home following the procedure. No patient required reoperation or readmission for spinal metastasis. Kyphoplasty is a suitable palliative treatment option for patients with advanced metastatic disease of the spine

Objective. To evaluate functional and oncological outcomes following sacral resection. Methods. Retrospective review of 97 sacral tumours referred to spinal or oncology units between 2004 and 2009. Results. 61 males, 37 females (average age of 47 (range 3 – 82). Average duration of symptoms 13 months. 17 metastatic disease, excluded from further discussion. Of the remainder 36/81(44%) underwent surgery – 21 excision, 9 excision and instrumented stabilisation, and 6 curettage. 13(16%) patients were inoperable - 8 advanced disease, 3 unable to establish local control, 2 recurrence. Colostomy was performed in 11/21(52%) patients who underwent excision. Deep wound infections in 6/21(29%). No difference in infection rates between definitive surgery with or without colostomy – 3/11(27%) vs. 3/10(30%). In the instrumented group, no colostomies were performed due to concerns about deep infection and none resulted (0/9). Radiological failure of stabilisation was noted in 7/9(78%). However, functionally, 3/9(33%) were mobilising independently, 3/9(33%) crutches, 2/9(22%) able to transfer and 1/9(11%) undocumented. Mean follow-up 25 months (range 0-70). Local recurrence in 9/36(25%) of operated patients. Metastasis occurred in 4/36(11%) and mortality 8/36(22%) although follow-up period was noted to be short. Conclusions. Results are comparable with current literature. Mechanical stabilisation for extensive sacral lesions is challenging. Despite radiological failure in 7/9 instrumented stabilisations, patients were relatively asymptomatic and only 1/9 required revision stabilisation surgery. By design none had colostomies and there were no deep infections

In this study we aim to establish which symptoms and signs are able to reliably predict the presence or absence of cauda equina syndrome. Prospective collection of data was carried out over 10 months on all patients referred with suspected cauda equina syndrome(CES) to a single spinal unit. 28 patients were referred. MRI was normal in 4 (14%) patients. 4 (14%) had disc prolapse causing CES and 3 (11%) had spinal metastatic disease. All patients with CES presented with low back pain, unilateral sciatica, urinary dysfunction (painless retention 2, incontinence 2), altered perianal sensation and abnormal anal tone. 1 described constipation. Of patients without CES or malignancy 21 (100%) complained of low back pain, 19 (90%) sciatica (15 unilateral, 4 bilateral), 12 urinary dysfunction (incontinence 5, reduced sensation 3, painless retention 2, urgency 1, terminal dribbling 1) and 5 described altered bowel habit. 7 (33%) exhibited altered perianal sensation and 1 (5%) abnormal anal tone. The patients with spinal metastases all described back pain but no sciatica. 2 had urinary retention and constipation with 1 having abnormal perianal sensation and anal tone. This study suggests abnormal anal tone (sensitivity 1.0, specificity 0.95) and altered perianal sensation (sensitivity 1.0, specificity 0.67) are the most reliable predictors of CES. Thorough clinical examination is essential. Back pain with bladder and/or bowel dysfunction without sciatica should raise the suspicion of malignancy

To review indications, complications and outcome for revision surgery in metastatic spinal disease. Retrospective review of casenotes and radiographs. 13 patients (9 male, 4 female) identified from a cohort of 222 patients who underwent surgery for spinal tumours between 1994- 2001. Indication for revision, complications, survival. Further recurrence (same or different level). Further surgery, neurological grade and pain score. Of 13 patients (4 Renal, 6 breast, 2 prostate, 1 myeloma) one is alive 101 months following revision. Two have been lost to follow up, 10 have died (mean survival 25.3 months post op). The mean time between primary and revision surgery was 10 months (range 1- 32 months). 4 disease progression (same level), 4 new level disease, 3 loss of fixation, 1 radiological collapse, 1 progressive kyphus. Approaches used: 4 anterior, 8 posterior, 1 posterior + anterior. The mean number of levels which required instrumentation on revision was 5. Modal pain score pre op 5, modal post op 3, minimum one point improvement. Preop modal Frankel grade E, postoperatively all preserved or improved one grade. Modal Karnofsky score preop 70 (30- 90), postop 80 (40-90)- all but one at least 10 point increase. Complications: 1Dural tear, 1 bacteraemia, 1 chylothorax, 1 loss of fixation. 3 patients required further surgery (range 4 months- 18 months, mean 11 months). Patients with metastatic disease may benefit from second procedures for recurrent disease whether locally or distant with excellent survival, low complications and good function

The skeleton is the most common site to be affected by metastatic cancer. The place of surgical treatment and of different techniques of reconstruction has not been clearly defined. We have studied the rate of survival of 94 patients and the results of the surgical treatment of 91 metastases of the limbs and pelvis, and 18 of the spine. Variables included the different primary tumours, the metastatic load at the time of operation, the surgical margin, and the different techniques of reconstruction. The survival rate was 0.54 at one year and 0.27 at three years. Absence of visceral metastases and of a pathological fracture, a time interval of more than three years between the diagnosis of cancer and that of the first skeletal metastasis, thyroid carcinoma, prostate carcinoma, renal-cell carcinoma, breast cancer, and plasmacytoma were positive variables with regard to survival. The metastatic load of the skeleton and the surgical margin were not of significant influence. In tumours of the limbs and pelvis, the local failure rate was 0% after biological reconstruction (10), 3.6% after cemented or uncemented osteosynthesis (28) and 1.8% after prosthetic replacement (53). The local failure rate after stabilisation of the spine (18) was 16.6%. There was local recurrence in seven patients (6.4%), and in four of these the primary tumour was a renal-cell carcinoma. The local recurrence rate was 0% after extralesional (24) and 8.2% after intralesional resection (85). Improvements in the oncological management of patients with primary and metastatic disease have resulted in an increased survival rate. In order to avoid additional surgery, it is essential to consider the expected time of survival of the reconstruction and, in bony metastases with a potentially poor response to radiotherapy, the surgical margin

Aims

The aim of this study was to assess the reliability of using MRI scans to calculate the Spinal Instability Neoplastic Score (SINS) in patients with metastatic spinal cord compression (MSCC).

Methods

A total of 100 patients were retrospectively included in the study. The SINS score was calculated from each patient’s MRI and CT scans by two consultant musculoskeletal radiologists (reviewers 1 and 2) and one consultant spinal surgeon (reviewer 3). In order to avoid potential bias in the assessment, MRI scans were reviewed first. Bland-Altman analysis was used to identify the limits of agreement between the SINS scores from the MRI and CT scans for the three reviewers.

Aims

The aim of this study was to explore the prognostic factors for postoperative neurological recovery and survival in patients with complete paralysis due to neoplastic epidural spinal cord compression.

Patients and Methods

The medical records of 135 patients with complete paralysis due to neoplastic cord compression were retrospectively reviewed. Potential factors including the timing of surgery, muscular tone, and tumour characteristics were analyzed in relation to neurological recovery using logistical regression analysis. The association between neurological recovery and survival was analyzed using a Cox model. A nomogram was formulated to predict recovery.

Percutaneous placement of pedicle screws is a well-established technique, however, no studies have compared percutaneous and open placement of screws in the thoracic spine. The aim of this cadaveric study was to compare the accuracy and safety of these techniques at the thoracic spinal level. A total of 288 screws were inserted in 16 (eight cadavers, 144 screws in percutaneous and eight cadavers, 144 screws in open). Pedicle perforations and fractures were documented subsequent to wide laminectomy followed by skeletalisation of the vertebrae. The perforations were classified as grade 0: no perforation, grade 1: < 2 mm perforation, grade 2: 2 mm to 4 mm perforation and grade 3: > 4 mm perforation. In the percutaneous group, the perforation rate was 11.1% with 15 (10.4%) grade 1 and one (0.7%) grade 2 perforations. In the open group, the perforation rate was 8.3% (12 screws) and all were grade 1. This difference was not significant (p = 0.45). There were 19 (13.2%) pedicle fractures in the percutaneous group and 21 (14.6%) in the open group (p = 0.73). In summary, the safety of percutaneous fluoroscopy-guided pedicle screw placement in the thoracic spine between T4 and T12 is similar to that of the conventional open technique.

An eight-week-old boy developed severe thoracic spondylodiscitis following pneumonia and septicaemia. A delay in diagnosis resulted in complete destruction of the T4 and T5 vertebral bodies and adjacent discs, with a paraspinal abscess extending into the mediastinum and epidural space. Antibiotic treatment controlled the infection and the abscess was aspirated. At the age of six months, he underwent posterior spinal fusion in situ to stabilise the spine and prevent progressive kyphosis. At the age of 13 months, repeat imaging showed lack of anterior vertebral body re-growth and he underwent anterior spinal fusion from T3 to T6 and augmentation of the posterior fusion. At the age of five years, he had no symptoms and radiographs showed bony fusion across the affected levels.

Spondylodiscitis should be included in the differential diagnosis of infants who present with severe illness and atypical symptoms. Delayed diagnosis can result in major spinal complications with a potentially fatal outcome.

Bertolotti’s syndrome is characterised by anomalous enlargement of the transverse process(es) of the most caudal lumbar vertebra which may articulate or fuse with the sacrum or ilium and cause isolated L4/5 disc disease.

We analysed the elective MR scans of the lumbosacral spine of 769 consecutive patients with low back pain taken between July 2003 and November 2004. Of these 568 showed disc degeneration. Bertolotti’s syndrome was present in 35 patients with a mean age of 32.7 years (15 to 60). This was a younger age than that of patients with multiple disc degeneration, single-level disease and isolated disc degeneration at the L4/5 level (p ≤ 0.05). The overall incidence of Bertolotti’s syndrome in our study was 4.6% (35 of 769). It was present in 11.4% (20 patients) of the under-30 age group.

Our findings suggest that Bertolotti’s syndrome must form part of a list of differential diagnoses in the investigation of low back pain in young people.
