Symptomatic spinal stenosis is a very common problem, and decompression surgery has been shown to be superior to nonoperative treatment in selected patient groups. However, performing an instrumented fusion in addition to decompression may avoid revision and improve outcomes. The aim of the SpInOuT feasibility study was to establish whether a definitive randomized controlled trial (RCT) that accounted for the spectrum of pathology contributing to spinal stenosis, including pelvic incidence-lumbar lordosis (PI-LL) mismatch and mobile spondylolisthesis, could be conducted. As part of the SpInOuT-F study, a pilot randomized trial was carried out across five NHS hospitals. Patients were randomized to either spinal decompression alone or spinal decompression plus instrumented fusion. Patient-reported outcome measures were collected at baseline and three months. The intended sample size was 60 patients.Aims

Surgical site infections following spinal surgery profoundly influence continued treatment, significantly impacting psychological and economic dimensions and clinical outcomes. Its reported incidence varies up to 20%, with the highest incidence amongst neuromuscular scoliosis and metastatic cord compression patients. We describe the first reported biphasic osteoconductive scaffold (Cerament G) with a logarithmic elution profile as a cumulative strategic treatment modality for adjacent spinal surgery infections. All patients who developed surgical site infections following instrumented fusion (May 2021-December 2021) had their demographics (age, sex), type and number of procedures, isolated organism, antibiotics given, comorbidities, and WHO performance status analysed. The infected wound was debrided to healthy planes, samples taken, and Cerament g applied. Thirteen patients were treated for deep SSI following spinal instrumentation and fusion procedures with intraoperative Cerament G application. There were four males and nine females with an average age of 40 ranging between 12 and 87. Nine patients underwent initial surgery for spinal deformity, and four were treated for fractures as index procedure. 77% of infections were attributable to MSSA and Cutibacteriousm acnes; others included Klebsiella, Pseudomonas and Streptococcus and targeted with multimodal cumulative therapy. A WHO performance score improved in 11 patients. In addition, there was no wound leak, and infection was eradicated successfully in 12/13 with a single procedure. This series shows the successful eradication of the infection and improved functional outcomes with Cerament G. However, the low numbers of patients in our series are an essential consideration for the broader applicability of this device.
The Magnetic Expansion Control Rod Device (Magec) allows controlled distraction of the immature spine for the treatment of early onset scoliosis. There disparity between the reported distraction on the external adjustment device (EAD) and true distraction achieved has not been commented on to date. This study aims to determine the disparity between ‘true’ (T) and ‘apparent’ (A) distraction. Our secondary aim was to assess truncal growth and development. Thirteen patients underwent an average of 4.4 (3–6) three monthly distractions. The amount of true distraction was determined by measuring the expansion gap on radiographs using the width of the rod as a conversion factor to allow for magnification. The total distraction to date was compared to the amount reported on the EAD. Sitting and standing heights were recorded at each distraction.Aim:
Methods:
A systematic review of the current literature to address the debate of the optimal surgical approach for the treatment of adolescent idiopathic scoliosis (AIS). All studies comparing anterior open instrumented surgery with posterior instrumented surgery in patients with AIS, written in English and published up until February 2010 were included. Electronic databases searched included Medline, PubMed and the Cochrane database using “AIS” and “surgery” as key words. Outcome measures considered to be important were specifically identified in each paper included: Blood loss (ml); operation time (mins); hospital stay (days); curve correction (sagittal and coronal); number of fused levels; pulmonary function, and complications.Study Purpose
Method
The use of the dynamic hip screw is common practice for the fixation of intertrochanteric fractures of the femur. The success of this procedure requires accurate guide wire placement. This can prove difficult at times and can result in repeated attempts leading to longer operating time, multiple tracks and more importantly greater radiation exposure to both patient and operating staff. We hypothesised that rather than using the standard anterior-posterior projected image (Figure 1) of a proximal femur, rotating the intensifier image (Figure 2) so that the guide wire appears to pass vertically makes it easier to visualise the projected direction of the guide wire. Fifty Specialist Registrars, thirty participating in the London hip meeting 2009, ten from Oxford and ten from Northern deanery orthopaedic rotations were involved in the study. They were presented with standard AP and rotated images of the femoral neck on paper using 135 degree template to replicate the DHS guide. The participants were asked to mark the entry point on the intertrochanteric area of femur on the image where they would have placed the guide wire. They did this on both standard AP and rotated images aiming for the centre of the head of the femur. Fig. 1 Standard AP image Fig. 2 Rotated imageIntroduction
