We studied 70 consecutive patients with adolescent idiopathic scoliosis who underwent corrective surgery. They were divided into two groups. In the study group of 38 patients one or more modern blood-conservation measures was used peri-operatively. The 32 patients in the control group did not have these measures. Both groups were similar in regard to age, body-weight, the number of levels fused and the type of surgery. Only two patients in the study group were transfused with homologous blood and these transfusions were ‘off-protocol’. Wastage of autologous pre-donated units was minimal (6 of 83 units). By contrast, all patients in the control group were transfused with homologous blood. In the study group there was a significant decrease (p = 0.005) in the estimated blood loss when all the blood-conservation methods were used. The use of blood-conservation measures, the lowering of the haemoglobin trigger for transfusion and the education of the entire team involved in the care of the patient can prevent the need for homologous blood transfusion in patients undergoing surgery for adolescent idiopathic scoliosis

Aims. The aim of this study was to evaluate improvements in the quality and safety of paediatric spinal surgery following the implementation of a specialist Paediatric Spinal Surgical Team (PSST) in the operating theatre. Patients and Methods. A retrospective consecutive case study of paediatric spinal operations before (between January 2008 and December 2009), and after (between January 2012 and December 2013) the implementation of PSST, was performed. A comparative analysis of outcome variables including surgical site infection (SSI), operating time (ORT), blood loss (BL), length of stay (LOS), unplanned staged procedures (USP) and transfusion rates (allogenic and cell-saver) was performed between the two groups. The rate of complications during the first two postoperative years was also compared between the groups. Results. There were 130 patients in the pre-PSST group and 277 in the post-PSST group. The age, gender, body mass index (BMI), preoperative Cobb angle of the major curve and the number of levels involved were similar between the groups. There were statistically significant differences in SSI, ORT, LOS, allogenic blood transfusion volume (ABTV), and USPs between the groups. There was a 94% decrease in the rate of SSI's in the post-PSST group. Patients in the post-PSST group had a mean reduction in ORT of 53 minutes (. sd. 7.7) (p = 0.013), LOS by 5.4 days (. sd. 1.8) (p = 0.019), and ABTV by 226.3 ml (. sd. 28.4) (p < 0.001). There were significantly more USPs in the pre-PSST group (6.2%) compared with the post-PSST group (2.9%) (p = 0.001). Multivariate regression showed that the effect of PSST remained significant for ORT, LOS, BL, ABVT and cell-saver amount transfused (p = 0.0001). The odds of having a SSI were tenfold higher and the odds of receiving a blood transfusion were 2.4 times higher, respectively, in the pre-PSST group (p = 0.004 and p = 0.011). The rate of complications within the first two postoperative years was significantly higher in the pre-PSST group (13.1%) compared with the post-PSST group (4.3%) (p < 0.001). Conclusion. The implementation of a PSST in the operating theatre significantly improves the outcomes in paediatric spinal surgery. Cite this article: Bone Joint J 2018;100-B:493–8

Despite the increasing prevalence of sleep apnoea, little information is available regarding its impact on the peri-operative outcome of patients undergoing posterior lumbar fusion. Using a national database, patients who underwent lumbar fusion between 2006 and 2010 were identified, sub-grouped by diagnosis of sleep apnoea and compared. The impact of sleep apnoea on various outcome measures was assessed by regression analysis. The records of 84 655 patients undergoing posterior lumbar fusion were identified and 7.28% (n = 6163) also had a diagnostic code for sleep apnoea. Compared with patients without sleep apnoea, these patients were older, more frequently female, had a higher comorbidity burden and higher rates of peri-operative complications, post-operative mechanical ventilation, blood product transfusion and intensive care. Patients with sleep apnoea also had longer and more costly periods of hospitalisation. . In the regression analysis, sleep apnoea emerged as an independent risk factor for the development of peri-operative complications (odds ratio (OR) 1.50, confidence interval (CI) 1.38;1.62), blood product transfusions (OR 1.12, CI 1.03;1.23), mechanical ventilation (OR 6.97, CI 5.90;8.23), critical care services (OR 1.86, CI 1.71;2.03), prolonged hospitalisation and increased cost (OR 1.28, CI 1.19;1.37; OR 1.10, CI 1.03;1.18). . Patients with sleep apnoea who undergo posterior lumbar fusion pose significant challenges to clinicians. . Cite this article: Bone Joint J 2014;96-B:242–8

Surgery of the spine is associated with blood loss and frequently transfusion, with consequent risk of infection and reactions. It also costly, and puts a strain on national blood banks. A new blood salvage device works by ‘washing’ and centrifuging the blood lost during surgery; which can then be re-transfused into the patient. In a retrospective study 46 consecutive spinal surgeries with Cell Saver were compared with 39 matched surgeries without. Blood loss and units transfused was obtained from the transfusion database and the anaesthetic record. Average blood loss in the Cell saver group was 1382ml compared to 1405ml in the pre-Cell Saver group. Average allogenic transfusion was 1.30 units with cell saver compared to 2.78 units without. An average 2.3 units of lost blood were re-infused in the Cell Saver group. 26 (57%) of the Cell Saver group require no allogenic blood at all, whereas only 10 (26%) of patients in the pre-Cell Saver group had no transfusions. One unit of blood costs £130.52, and the Cell saver device costs £100 per patient. The average cost per patient in the Cell saver group was £270 (any transfusion plus cost of Cell Saver), compared to an average of £368.50 in the pre-Cell Saver group: a saving of £92.50. The Cell Saver decreased blood transfusions by 46% per patient and by 40% overall, a saving of £92.50 per patient. The number of patients receiving no allogenic blood increased by 31%

Aims

Closed suction subfascial drainage is widely used after instrumented posterior spinal fusion in patients with a spinal deformity. The aim of this study was to determine the effect of this wound drainage on the outcomes in patients with adolescent idiopathic scoliosis (AIS). This was a further analysis of a randomized, multicentre clinical trial reporting on patients after posterior spinal fusion using segmental pedicle screw instrumentation. In this study the incidence of deep surgical site infection (SSI) and chronic postoperative pain at two years’ follow-up are reported.

Aims

The aim of this study was to evaluate whether, after correction of an adolescent idiopathic scoliosis (AIS), leaving out the subfascial drain gives results that are no worse than using a drain in terms of total blood loss, drop in haemoglobin level, and opioid consumption.

Purpose. To evaluate efficacy of blood conservation strategies on transfusion requirements in adult scoliosis surgery and establish a protocol for cross matching. Methods and Results. Retrospective review of 50 consecutive adult scoliosis patients treated using anterior only(14,28%), posterior only(19,38%) or combined(17,34%) approaches. All patients were anaesthetised by the same anaesthetist implementing a standard protocol using cell salvage, controlled hypotension and antifibrinolytics. Mean age was 24.6 years. BMI was 21.9. On an average 9.5(6-15) levels were fused, with an average duration of surgery of 284.6(130-550) minutes. Antifibrinolytics were used in 31(62%) of the patients which included Aprotinin in 21(42%) and Tranexamic acid in 10(20%). Patients on antifibrinolytics had a significantly (p<0.05) lower blood loss (530ml) as compared to other patients (672ml). Mean volume of the cell saved blood re-transfused was 693.8 ml and mean postoperative HB level dropped to 10.7 g/dl(7.7-15) from a mean preoperative of 13.3 g/dl(10-17). 7(42%) with combined approaches and 3(15.8%) with posterior only approach required blood transfusion, 4/50(8%) of which required intra while 6/50(12%) required intra and postoperative transfusion. None of the patients having anterior surgery alone required blood transfusion. Conclusion. Use of antifibrinolytics reduces the need for blood transfusion in scoliosis surgery. For anterior surgery alone, we do not cross match

Aims

The aim of this study was to reassess the rate of neurological, psoas-related, and abdominal complications associated with L4-L5 lateral lumbar interbody fusion (LLIF) undertaken using a standardized preoperative assessment and surgical technique.

We studied the use of autologous pre-donated blood transfusion in surgery for scoliosis in 45 patients who were divided into two groups; 27 who pre-donated autologous blood (group 1) and 18 who were planned recipients of allogenic blood (group 2). Normovolaemic haemodilution and intra-operative blood salvage was used in six patients in group 1 and three patients in group 2. The two groups did not differ significantly with respect to age, American Society of Anaesthesiologists score, mean operative time, number of vertebral segments fused, total blood loss, length of stay in intensive care and length of stay in hospital. The risk of requiring allogenic blood transfusion was found to be significantly less in group 1 (7.4% ν 88.9%, p < 0.001). Only 5.21% of autologous units were wasted. Although intra-operative blood salvage reduced the total blood loss in both groups, it did not affect the need for subsequent allogenic transfusion or reduce the number of pre-donated autologous units which were given (p < 0.67). Autologous blood transfusion required extra time, personnel, resources and cost £28.88 per patient more than allogenic transfusion, however, the projected costs at May 2002 make this programme cost-effective by £51.54 per patient. Pre-donated autologous blood transfusion is acceptable and safe in scoliosis surgery. It significantly reduces the subsequent requirement of allogenic transfusion. Although the cost is currently more than allogenic transfusion, with the increase in the costs of the latter and the decrease in potential donors which is anticipated, pre-donation of autologous blood will become comparatively cost-effective

To compare the effect of intraoperative red cell salvage on blood transfusion and cost in patients undergoing idiopathic scoliosis surgery. Retrospective. 37 patients (36 females, 1 male) underwent scoliosis surgery from February 2007 to October 2008. Intraoperative red cell salvage (Group 1) was used. They were compared with 28 patients (23 females, 5 males) operated from January 2005 to December 2006 without the use of cell salvage (Group 2). 36 patients in group 1 had posterior surgery and 1 had anterior surgery. In Group 2, 20 patients had posterior surgery, 7 anterior and 1 patient had anterior and posterior surgery. Both groups were comparable for age, number of levels fused, preoperative haemoglobin and haematocrit values. Amount of perioperative blood transfusion, costs. 14 patients (50%) in group 2 had blood transfusion whereas only 6 (16%) were transfused blood in group 1. Average blood loss in group 1 was 1076 mls (range 315-3000) and 1626mls (419-4275) in group 2. An average of 2 units of packed red blood cells per patient was processed by the cell salvage system. Postoperative haemoglobin, haematocrit and hospital stay were comparable in both groups. Cost analysis shows the use of cell salvage is cost beneficial by £116.60 per case. The use of red blood cell salvage reduces the amount of blood transfusion and is cost beneficial

Background:. Following lumbar spine surgery patients with a high BMI appear to have increased post-operative complications including surgical site infections (SSI), urinary complications, increased anaesthetic/operative time and a greater need for post-operative blood transfusion. There is no current evidence, however, analysing the effect of BMI on functional outcome. Purpose:. We aimed to analyse the effect of BMI on functional outcome following lumbar spine surgery. Study Design:. Retrospective Cohort Study. Patient Sample:. 131. Outcome Measures:. Outcome measures included mean post-operative Oswestry Disability Index (ODI) at six and twelve months, the incidence of SSI, mean operative time and the requirement for post-operative blood transfusion. Methods:. Patients that underwent lumbar spinal surgery between September 2010 and November 2013 were identified retrospectively and categorised into discectomy, decompression, fusion and revision is created. A BMI threshold of 30 was used to group patients as non-obese or obese. Univariate analysis was used to compare the effect of BMI on the above outcome measures. Results:. Post-operative complication rates were higher in the obese group in each category. However, there was no significant difference in the post-operative ODI at six ad twelve months post-operatively. Conclusions:. Increased BMI is related to increased post-operative complications but is not associated with a poorer functional outcome in the short to mid-term

This review provides a concise outline of the advances made in the care of patients and to the quality of life after a traumatic spinal cord injury (SCI) over the last century. Despite these improvements reversal of the neurological injury is not yet possible. Instead, current treatment is limited to providing symptomatic relief, avoiding secondary insults and preventing additional sequelae. However, with an ever-advancing technology and deeper understanding of the damaged spinal cord, this appears increasingly conceivable. A brief synopsis of the most prominent challenges facing both clinicians and research scientists in developing functional treatments for a progressively complex injury are presented. Moreover, the multiple mechanisms by which damage propagates many months after the original injury requires a multifaceted approach to ameliorate the human spinal cord. We discuss potential methods to protect the spinal cord from damage, and to manipulate the inherent inhibition of the spinal cord to regeneration and repair. Although acute and chronic SCI share common final pathways resulting in cell death and neurological deficits, the underlying putative mechanisms of chronic SCI and the treatments are not covered in this review.

Aims

The outcome following the development of neurological complications after corrective surgery for scoliosis varies from full recovery to a permanent deficit. This study aimed to assess the prognosis and recovery of major neurological deficits in these patients, and to determine the risk factors for non-recovery, at a minimum follow-up of two years.

The purpose of this study was to determine whether patients with a burst fracture of the thoracolumbar spine treated by short segment pedicle screw fixation fared better clinically and radiologically if the affected segment was fused at the same time. A total of 50 patients were enrolled in a prospective study and assigned to one of two groups. After the exclusion of three patients, there were 23 patients in the fusion group and 24 in the non-fusion group. Follow-up was at a mean of 23.9 months (18 to 30). Functional outcome was evaluated using the Greenough Low Back Outcome Score. Neurological function was graded using the American Spinal Injury Association Impairment Scale. Radiological outcome was assessed on the basis of the angle of kyphosis. Peri-operative blood transfusion requirements and duration of surgery were significantly higher in the fusion group (p = 0.029 and p < 0.001, respectively). There were no clinical or radiological differences in outcome between the groups (all outcomes p > 0.05). The results of this study suggest that adjunctive fusion is unnecessary when managing patients with a burst fracture of the thoracolumbar spine with short segment pedicle screw fixation

Aims

With resumption of elective spine surgery services in the UK following the first wave of the COVID-19 pandemic, we conducted a multicentre British Association of Spine Surgeons (BASS) collaborative study to examine the complications and deaths due to COVID-19 at the recovery phase of the pandemic. The aim was to analyze the safety of elective spinal surgery during the pandemic.

To review blood transfusion practices during elective spinal surgery procedures. Prospective clinical audit. All patients who underwent elective spinal surgery between January 2009 and March 2009. Crossmatch: Transfusion ratio (C: T ratio); Transfusion index (TI) (Evaluates cost-effective crossmatch). British Haematological society standards are C:T ratio= 2.5:1 and TI>0.5. Data was collected from electronic records of blood bank, pathology system (NOTIS) and review of patient notes. A total of 194 patients underwent elective spinal surgery in our unit. (Cervical spine = 15, Thoracic spine = 3, Vertebroplasty = 10, Lumbar spine = 142, Deformity = 31, other = 8). Of these, 62 patients had 197 blood products crossmatched but only 37 units were used. C:T ratio in lumbar spine surgery was 22:1. However C: T ratio in cervical spine procedures, thoracic spine and deformity correction were 6:1, 11:0 and 4:1 respectively. TI was <0.5 in all procedures except deformity surgery (TI=1). Over- ordering of blood products is still common in spinal surgery as routine blood transfusion may not be required in most elective procedures. Therefore implementing Electronic Issue (EI) of blood products for elective spinal procedures for non deformity procedures can be a cost effective and safe practice

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.

Aims

To report the outcome of spinal deformity correction through anterior spinal fusion in wheelchair-bound patients with myelomeningocele.

Aims

Spinal fusion remains the gold standard in the treatment of idiopathic scoliosis. However, anterior vertebral body tethering (AVBT) is gaining widespread interest, despite the limited data on its efficacy. The aim of our study was to determine the clinical efficacy of AVBT in skeletally immature patients with idiopathic scoliosis.

Aims

To report the surgical outcome of patients with severe Scheuermann’s kyphosis treated using a consistent technique and perioperative management.
