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

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.

Aims

Traumatic central cord syndrome (CCS) typically follows a hyperextension injury and results in motor impairment affecting the upper limbs more than the lower, with occasional sensory impairment and urinary retention. Current evidence on mortality and long-term outcomes is limited. The primary aim of this study was to assess the five-year mortality of CCS, and to determine any difference in mortality between management groups or age.

Aims

To determine the value of scoliosis surgery, it is necessary to evaluate outcomes in domains that matter to patients. Since randomized trials on adolescent idiopathic scoliosis (AIS) are scarce, prospective cohort studies with comparable outcome measures are important. To enhance comparison, a core set of patient-related outcome measures is available. The aim of this study was to evaluate the outcomes of AIS fusion surgery at two-year follow-up using the core outcomes set.

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

To describe complications and reoperation rates associated with degenerative spinal deformity surgery. A retrospective review of prospectively collected data from a single spinal surgeon in the United Kingdom. A total of 107 patients who underwent surgery, of 5 or more levels, for primary degenerative kyphoscoliosis between 2006 and 2012 were identified. Clinical notes were reviewed and post-operative complications, reoperation rates, length of follow up and mortality were analysed. A total of 107 patients, average aged 66.5 years (range 52 – 85), with 80% women. 105 patients underwent posterior surgery, two patients required both anterior and posterior surgery. The average number of instrumented levels was 8.3; 10% 5 levels, 15% 6 levels, 11% 7 levels, 14% 8 levels, 15% 9 levels and 35% had fusions of 10 levels and above. 58% included fixation to sacrum or pelvis. 93% had a decompression performed and 30% had an osteotomy. There were 40 complications recorded within the follow-up period. Infection occurred in 7 patients (6.5%). All were successfully managed with debridement, antibiotic therapy and retention of implants. There were 4 dural tears (3.7%). One patient developed a post-operative DVT (0.9%). No patients sustained cord level deficits. Prevalence of mechanical complications requiring re-operation was 26% (28 patients). 5 patients (4.7) required revision surgery for symptomatic pseudarthrosis, 7 patients (6.5%) underwent revision fixation for metal work failure (broken rods/screw pull-out) and 16 patients (14.9%) underwent revision surgery to extend fixation proximally or distally due to adjacent segment disease (symptomatic proximal junction kyphosis 4.7%; osteoporotic fracture 3.7% and junctional/nerve root pain 6.5%). Overall reoperation rate was 32.5% at an average of 1.9 years following primary surgery (range 1 week–6 years). 37% patients remain on regular outpatient review (average 3.8 years following first surgery; range 2–6 years). 52% have been discharged after a mean follow-up of 2.3 years. 11 patients had died since their surgery (10.2%) at an average 4.1 years following their spinal surgery (range 1 –5.9 years). Overall complication rate was 37.3%. 32.5% of patients were re-operated for infective or mechanical complications. 52% of patients had been discharged at an average of 2.3 years following their surgery. 10.2% of patients had died within 6 years of surgery

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.

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.
