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

To evaluate functional and oncological outcomes following resection of primary malignant bone tumours.

Primary malignant tumours of the sacrum are rare, arising from bony or neural elements, or bone marrow in haematological malignancies.

Management of these lesions is dictated by anatomical considerations and the behaviour of tumours. The three key issues which arise are the adequacy of tumour resection, mechanical stabilisation and the need for colostomy.

A retrospective review of the surgical management of primary malignant sacral tumours from 2004 - 2009.

The study included 46 patients (34 males, 12 females) with an average age of 49 (range 7 – 82). Median duration of symptoms before presentation was 26 months.

10 patients had inoperable tumours at presentation. 6 patients had chemotherapy. 2 patients opted for palliative radiotherapy. 1 patient was unfit for surgery.

25 patients (54%) underwent surgical resection. 8 underwent instrumented stabilisations with fibula strut graft vs. 17 uninstrumented.

Colostomy was performed in 10 patients (40%). Mean follow post-operatively was 19.0 months.

Wound healing problems were present in 5/25 (20%). There was no difference in infection rates between definitive surgery with and without colostomy. Mechanical failure of stabilisation was noted in 75%. There was one peri-operative death.

Local recurrence occurred in 12%(3/25) of operated patients although follow-up period was noted to be short.

Mechanical stabilisation for extensive lesions in the sacrum are particularly challenging in tumour surgery. Despite radiological failure in 7/8 instrumented stabilisations, patients were relatively asymptomatic and only 1/8 required revision stabilisation surgery.

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. Results. Lung and other bone metastases at the time of surgery were observed in ten and eight patients, respectively. Three patients experienced local tumour recurrences at the operated site. The five- and ten-year CSS rates in the 22 patients with DTC were 77% and 52%, respectively. Pre- and postoperative disability and operative site tumour recurrence were identified as risk factors for short postoperative survival. Conclusion. Metastasectomy for resectable SM from DTC yielded favourable results and has the potential to improve survival. Cite this article: Bone Joint J 2023;105-B(5):575–582

Introduction. Degenerative spondylosis (DS) represents a challenging condition to diagnose and treat. There are multiple modalities to investigate DS including X-ray, MRI and CT, but symptoms may not be equivocal to DS to support the clinical findings. The investigation of metastases commonly utilises SPECT/CT for identification of areas of increased osteoblastic activity to denote disease. The aim of the study was to analyse the prevalence of asymptomatic DS in a consecutive hospital cohort of oncology patients who had SPECT/CT for investigation of metastases. Methods. Oncology patients who underwent SPECT/CT at St. George's Hospital were analysed between 2015–2019. Exclusion criteria: back pain, inflammatory disorders, metastases, trauma, infection. Radiology reports were examined for DS and anatomical distribution of tracer uptake. Results. A total of 1182 patients had a Whole-Body SPECT CT used for the spinal analysis. After exclusions (age >80 [n=260], non-cancer [n=318], back pain [n=72]), 522 reports with cancer were utilised. Mean age was 65 (4–80). Age and distribution of DS are given in the table. Conclusion. The prevalence of radiological asymptomatic DS is prevalent in large proportions of patients without back pain, and its incidence increases with age. Approximately 60% of 60 year old and 70% of 70 years old patients have asymptomatic DS in the lumbosarcal region. We conclude that SPECT/CT will detect radiographic degenerative spondylosis in an asymptomatic hospital cohort and this prevalence increase with age. Therefore, this modality of imaging must be utilised with caution when investigating potential pain generators. For any figures or tables, please contact the authors directly

Aims. The aim of this study was to determine whether there is an increased prevalence of scoliosis in patients who have suffered from a haematopoietic malignancy in childhood. Methods. Patients with a history of lymphoma or leukaemia with a current age between 12 and 25 years were identified from the regional paediatric oncology database. The medical records and radiological findings were reviewed, and any spinal deformity identified. The treatment of the malignancy and the spinal deformity, if any, was noted. Results. From a cohort of 346 patients, 19 (5.5%) had radiological evidence of scoliosis, defined as a Cobb angle of > 10°. A total of five patients (1.4% of the total cohort) had a Cobb angle of > 40°, all of whom had corrective surgery. No patient with scoliosis had other pathology as a possible cause of the scoliosis and all had been treated with high doses of steroids for leukaemia, either acute or chronic myeloid, or acute lymphoblastic. Conclusion. There is an increased prevalence of idiopathic-like scoliosis and larger curves (Cobb angle of > 40°) associated with childhood leukaemia, which has not been previously reported in the literature. Causative factors may relate to the underlying disease process and/or its treatment. Cite this article: Bone Joint J 2021;103-B(8):1400–1404

Aims. With recent progress in cancer treatment, the number of advanced-age patients with spinal metastases has been increasing. It is important to clarify the influence of advanced age on outcomes following surgery for spinal metastases, especially with a focus on subjective health state values. Methods. We prospectively analyzed 101 patients with spinal metastases who underwent palliative surgery from 2013 to 2016. These patients were divided into two groups based on age (< 70 years and ≥ 70 years). The Eastern Cooperative Oncology Group (ECOG) performance status (PS), Barthel index (BI), and EuroQol-5 dimension (EQ-5D) score were assessed at study enrolment and at one, three, and six months after surgery. The survival times and complications were also collected. Results. In total, 65 patients were aged < 70 years (mean 59.6 years; 32 to 69) and 36 patients were aged ≥ 70 years (mean 75.9 years; 70 to 90). In both groups, the PS improved from PS3 to PS1 by spine surgery, the mean BI improved from < 60 to > 80 points, and the mean EQ-5D score improved from 0.0 to > 0.7 points. However, no significant differences were found in the improvement rates and values of the PS, BI, and EQ-5D score at any time points between the two groups. The PS, BI, and EQ-5D score improved throughout the follow-up period in approximately 90% of patients in each group. However, the improved PS, BI, and EQ-5D scores subsequently deteriorated in some patients, and the redeterioration rate of the EQ-5D was significantly higher in patients aged ≥ 70 than < 70 years (p = 0.027). Conclusion. Palliative surgery for spinal metastases improved the PS, activities of daily living, and quality of life, regardless of age. However, clinicians should be aware of the higher risk of redeterioration of the quality of life in advanced-age patients. Cite this article: Bone Joint J 2020;102-B(12):1709–1716

Aims

To determine the major risk factors for unplanned reoperations (UROs) following corrective surgery for adult spinal deformity (ASD) and their interactions, using machine learning-based prediction algorithms and game theory.

Patients with peripheral primary bone tumours are often identified and referred at an early stage to a regional tumour service according to established guidelines. In patients with primary bone tumours of the spine, however, the definitive management or outcome of such patients is being prejudiced by preliminary intervention from non-specialist services prior to their referral. Objective: To audit the standards of management of patients with primary bone tumours of the spine referred to a regional tumour service. Retrospective review of case notes and radiology. Subjects: Patients with primary bone tumour of the spine managed at the Orthopaedic Spine Unit with the Regional Bone Tumour Service in Newcastle Upon Tyne Hospitals NHS Trust. Referral to tumour service, prior intervention, operative treatment, survival, factors affecting definitive management. 31 of 39 (16 benign, 23 malignant) patients were initially referred from primary care to services other than the regional tumour service, most commonly neurosurgery (11/39) and paediatric oncology (4/39). Seven of 39 of these patients had undergone interventions prior to their referral to the tumour service, which may have negatively impacted their definitive management or curative surgery. These tumours present complex issues regarding their definitive management to optimise outcome. Closer links between departments are required to enable the multidisciplinary management of primary bone tumours of the spine. Prior surgical intervention may compromise cure. Those involved in their management should be encouraged to liaise with their regional bone tumour service to improve outcome

Introduction. Metastatic involvement of the lumbo-sacral junction/sacrum usually signifies advanced disease. The aim of this study was to report our results on the management of patients with metastases referred to this anatomical region over the last 5 years (July 2006- July 2010). Methods. Retrospective analysis from a comprehensive spinal oncology database. Results. During this period, a total of 14 patients (mean age 65.6 years (58-87), 8 female, 6 male) were referred to our unit. The majority had symptoms of pain and neurological deterioration (11) with onset of pain considerably longer than neurology symptoms (296 days (7-1825) versus 7 days (1-28); 3 were non-ambulatory at presentation. The primary tumours were Renal cell (4), Breast (2), Prostate (2), GI (2), unknown primary (2), lung (1) and neuroendocrine (1). Operative procedures performed were decompression with lumbo-pelvic stabilisation (5), decompression with(out) biopsy (7), posterior decompression/reconstruction with anterior excision/stabilisation (1) and laminectomy with sacroplasty (1). There were 8/14 (57%) complications including neurological deterioration (2), wound infection (2) and metalwork revision (1). Post-operatively, 7 patients received radiotherapy, 3 improved one Frankel grade and the others remained stable. All patients were ambulatory. The mean survival was 412 days (105-1005) and most patients returned either back to their own home (8) or a nursing home (4). Conclusion. The incidence of metastases in this region is relatively uncommon. Surgical intervention has a high complication rate (8/14, 57%) but can be important in restoring/preserving neurological function, assisting with ambulatory function and allowing patients to return to their previous accommodation
