Introduction. Scoliosis surgery is a life-changing procedure, but not devoid of perioperative complications. Often patients' scoring systems do not cover their real-life needs, including return to pre-surgery activity. Return to school, physical education (PE) is an important indirect marker of recovery. Although anterior spinal fusion (ASF) may have advantages, compared to posterior spinal fusion (PSF), because of motion-saved segments, there is a paucity of literature about post-operative return to school/PE in the compared groups. Aim. To determine the recovery time for patients with scoliosis who underwent anterior spinal fusion (ASF) and posterior spinal fusion (PSF). Design. Prospective cohort. Methods. Patients undergoing Adolescent Idiopathic Scoliosis (AIS) surgery from 2018–2019, were examined. We excluded no-AIS and over 18y patients. The Scoliosis Sports Survey validated questionnaire was administered post-operatively regarding return to school, PE and other physical activities. ASF and PSF groups were subcategorised into: Selective Anterior Thoracic Fusion (SATF), Thoracolumbar Fusion (TLF), Short Posterior Spinal Fusion (SPSF) and Long Posterior Spinal Fusion (LPSF) procedures. Hospital length of stay (HLOS) and ICU LOS were recorded. Results. A total of 81 patients were contacted and 43 responded to the survey. The different procedures, return to school / PE, HLOS / ICU LOS, costoplasty are all analysed as shown below in Table 1. Conclusions. Anterior and posterior fusions had similar return to school rates at 1–3 months. The TLF and 2-stages groups returned to school the quickest, whilst the SATF had the longest return time. PSF patients returned to PE faster than ASF. Costoplasty, did not affect return time to school and PE. Further research assessing shorter fusions benefits should be conducted.

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.

Introduction. Reported incidence of DVT after spinal surgery ranges from 0-15% and PE 0.5-2.7%. Theoretically, manipulation of the vessels and venous stasis caused by retraction during anterior lumbar inter-body fusion may increase the propensity for thrombosis. The reported incidence of DVT and PE following major abdominal and pelvic surgery are high (up to 23%) and all these patients routinely receive chemical prophylaxis. Aim. Should patients undergoing ALIF surgery receive chemical prophylaxis routinely?. Materials and Methods. Retrospective review of ALIF procedures done between Jan 2007- Jan 2010. Review of case notes, radiology reports and telephone call to the patients to exclude DVT. Total of 76 patients underwent ALIF during this period. Forty six were female(60.5%) and 36 were 2 level fusions(47%). L5-S1 being commonly fused (76%) followed by L4-L5 (23%). Average surgical time from theatre records is 115 minutes(31-369 minutes). All patients received mechanical prophylaxis in the form of thigh length TED stockings. None of the patients were on treatment for DVT prior to surgery. Results. Three patients (3.9%) had Doppler proved DVT which required anticoagulation treatment. There was no reported incidence of PE. Discussion. There is no definite evidence in the literature to suggest ALIF surgery has higher incidence of thromboembolic complications, though theoretical possibility of increased risk. Current study suggests that incidence is 3.9% with mechanical prophylaxis alone which is very small when compared to incidence after major abdominal, pelvic or gynaecological procedures. Our small study sample suggests routine use of chemical prophylaxis to reduce the risk of DVT for anterior lumbar inter-body fusion is not justified

To assess screw malposition rates and complications associated with pedicle screw insertion using 3D navigation technology. A retrospective study was undertaken for all cases where O-arm® and StealthStation® systems were used over a 2-year period. The primary outcome measure was return to theatre rates for pedicle screw malposition. A total of 938 screws were inserted (934 thoracolumbar and 4 cervical), and 103 patients underwent spinal fixation using O-arm® and StealthStation® navigation. 64 were revision cases and 39 primary cases. Average number of levels was 4.6. There were a total of 10 complications: 3 infections, 1 DVT, 1 PE, 1 fast atrial fibrillation (AF), 1 screw malposition, 1 non-union, 1 undisplaced vertebral body fracture and 1 nerve root compression following osteotomy. The percentage return to theatre for screw malposition using 3D navigation was 1% of patients and 0.1% of pedicle screws. No patients developed permanent neurological compromise. These systems provide accuracy that is comparable to traditional 2D fluoroscopic techniques. We advocate their use in the safe insertion of pedicle screws in complex revision deformity cases where original anatomical landmarks are absent or obscured. We also believe that radiation exposure is considerably less with navigation especially in these complex and revision cases

Aims

The timing of surgical fixation in spinal fractures is a contentious topic. Existing literature suggests that early stabilization leads to reduced morbidity, improved neurological outcomes, and shorter hospital stay. However, the quality of evidence is low and equivocal with regard to the safety of early fixation in the severely injured patient. This paper compares complication profiles between spinal fractures treated with early fixation and those treated with late fixation.

Purpose of Study. To investigate current practice of thromboprophylaxis in major UK spinal centres for both trauma and elective surgery, and to asses compliance with NICE guidelines. Methods. A telephonic survey was carried out which comprised of questions relating to current practice of thromboprophylaxis in major spinal units across the UK. Questions probed practice with regard to trauma versus elective surgery, agents used, timing of prophylaxis, length of treatment and whether practice has changed since the introduction of NICE guidelines. Results. Thirty specialised centres were contacted. Twenty eight centres followed NICE recommendations, with 2 centres using their own protocol. Four centres made changes to their existing protocols after the emergence of NICE guidelines. GCS (Graduated compression stockings) were uniformly used by all, with most centres using flowtron boots and/or foot in addition. The practices are differing within centres for elective versus trauma surgery. Of note, in patients with an acute cord injury, 20 centres used combined pre operative prophylaxis whereas 10 centres used only mechanical prophylaxis. Three units (10 %) describe a noticeable rise in complications related to chemoprophylaxis, whilst only one unit has reported a PE death within the last year. Discussion. Our survey assesses compliance to the NICE guidelines by the UK's spinal units. Mechanical prophylaxis appears to be the most common mode of prophylaxis understandably due to predictable safety profile. Use of chemo-prophylaxis varies amongst different surgeons and centres. Rather than a result of evidence based practice, the decision appears to be related to the previous experiences of that unit. Although the NICE guidelines provide a reasonable platform to the practice of thromboprophylaxis, more studies are required to evaluate the risks of thrombosis and bleeding events in spinal surgery

Object. Giant thoracic discs (occupying more than 40% of the spinal canal) are a difficult surgical pathology. They are increasingly being recognized as or particular subset of thoracic disc pathology. It has been recommended that an aggressive surgical approach of open 2 level verteberectomy and instruments should be utilized.21 However Retropleural thoracotomy provides the shortest direct route to the anterior thoracic spine and avoids pleural cavity entry making it an ideal if infrequently used approach to access ventral thoracic and thoracolumbar spine abnormalities. We present a detailed description of our experience utilising this approach, for the treatment of Giant Thoracic discs without the need for vertebrectomy or instrumentation. Methods. A prospective cohort of patients with Giant thoracic discs operated on utilizing the mini open retropleural thoracotomy technique was used, intra-operative and post-operative complications and length of post-op stay. Functional outcome and pain scores, were also prospectively recorded using SF-36, Oswestry Disability Index (ODI), and visual analogue pain scores (VAS). Results. 17 patients underwent a retropleural thoracotomy for Giant thoracic disc between 2001 and 2010. There were 8 male and 9 female patients with a median age of 50 years (range 35 – 70). The surgical level was T8/9 (58%) followed by T10/11 (33%) and finally T11/12 (8%). 1 patient had redo surgery following a failed primary discectomy at another institution. The mean post-operative length of stay was 12.8 days Intra-operative complications included 5 pleural tears during the approach. Chest drain was placed post-op in one patient. The tears were primarily repaired and the approach did not have to be abandoned. 2 patients had an intra-operative CSF leak (1 had intradural disc erosion). Post-operative complications included 1 pleural effusion, 1 patient had pneumonia and a PE, 1 patient died from an unrelated respiratory tract infection of the lung (opposite to the side of the approach) 40 days after surgery. Conclusion. Large calcified thoracic disc herniations can be a very challenging pathology. The retropleural transthoracic approach can be employed safely in this setting with acceptable morbidity for the patient

Aims

To evaluate the incidence of primary venous thromboembolism (VTE), epidural haematoma, surgical site infection (SSI), and 90-day mortality after elective spinal surgery, and the effect of two protocols for prophylaxis.

Aims

We reviewed 34 consecutive patients (18 female-16 male) with isthmic spondylolysis and grade I to II lumbosacral spondylolisthesis who underwent in situ posterolateral arthodesis between the L5 transverse processes and the sacral ala with the use of iliac crest autograft. Ten patients had an associated scoliosis which required surgical correction at a later stage only in two patients with idiopathic curves unrelated to the spondylolisthesis.

The aim of this study was to determine whether obesity affects pain, surgical and functional outcomes following lumbar spinal fusion for low back pain (LBP).

A systematic literature review and meta-analysis was made of those studies that compared the outcome of lumbar spinal fusion for LBP in obese and non-obese patients. A total of 17 studies were included in the meta-analysis. There was no difference in the pain and functional outcomes. Lumbar spinal fusion in the obese patient resulted in a statistically significantly greater intra-operative blood loss (weighted mean difference: 54.04 ml; 95% confidence interval (CI) 15.08 to 93.00; n = 112; p = 0.007) more complications (odds ratio: 1.91; 95% CI 1.68 to 2.18; n = 43858; p < 0.001) and longer duration of surgery (25.75 mins; 95% CI 15.61 to 35.90; n = 258; p < 0.001). Obese patients have greater intra-operative blood loss, more complications and longer duration of surgery but pain and functional outcome are similar to non-obese patients. Based on these results, obesity is not a contraindication to lumbar spinal fusion.
