It has become increasingly important to conduct studies assessing clinical outcomes, reoperation rates, and revision rates to better define the indications and efficacy of lumbar spinal procedures and its association with symptomatic adjacent segment degeneration (sASD). Adjacent segment degeneration (ASD) is defined as the radiographic change in the intervertebral discs adjacent to the surgically treated spinal level. SASD represents adjacent segment degeneration which causes pain or numbness due to post-operative spinal instability or nerve compression at the same level. The most common reason for early reoperation and late operation is sASD, therefore is in our best interest to understand the causes of ASD and make steps to limit the occurrence. A comprehensive literature search was performed selecting Randomized controlled trials (RCTs) and retrospective or prospective studies published up to December 2023. Meta-analysis was performed on 38 studies that met the inclusion criteria and included data of clinical outcomes of patients who had degenerative disc disease, disc herniation, radiculopathy, and spondylolisthesis and underwent lumbar fusion or motion-preservation device surgery; and reported on the prevalence of ASD, sASD, reoperation rate, visual analogue score (VAS), and Oswestry disability index (ODI) improvement.Background
Method
To investigate whether the duration of pain has an influence on the clinical outcomes of patients with low back pain (LBP) managed through the North East of England Regional Back Pain and Radicular Pain Pathway (NERBPP). The NERBPP is a clinical pathway based upon NICE guidelines (2009) for LBP. Patients with LBP referred onto the NERBPP by their General Practitioner (GP) between May 2015 and January 2017 were included in this evaluation. Data from 635 patients, who provided pre and post data for pain (Numerical rating scale [NRS]), function (Oswestry Disability Index [ODI]) and quality-of-life (EuroQol [EQ5D]), were analysed using a series of covariate adjusted models in SPSS. Patients were categorised into four groups based upon pain duration: <3months, ≥3 to <6months, ≥6months to <12months, ≥12months.Aims
Patients and Methods
We present a case series of five patients who had revision surgery
following magnetic controlled growing rods (MGCR) for early onset
scoliosis. Metallosis was found during revision in four out of five
patients and we postulated a mechanism for rod failure based on
retrieval analysis. Retrieval analysis was performed on the seven explanted rods.
The mean duration of MCGR from implantation to revision was 35 months
(17 to 46). The mean age at revision was 12 years (7 to 15; four
boys, one girl).Aims
Patients and Methods
The K2M MESA Rail is a new implant with a unique beam-like design which provides increased rigidity compared with a standard circular rod of equivalent diameter potentially allowing greater control and maintenance of correction. The aim of this study was to review our early experience of this implant. We retrospectively reviewed the case notes and radiographs of all consecutive cases of spinal deformity correction in which at least one rail was used. All radiological measurements were made according to the Scoliosis Research Society definitions. Since June 2012 thirty-three cases of spinal deformity correction were performed using the K2M Rail system. One case was excluded as there were no pre-operative radiographs. Median age was 15 years; there were 23 females. There were 26 scoliosis cases of which two had associated Chiari malformation, three were neuromuscular, and the remainder were adolescent idiopathic cases. Six patients had kyphotic deformity secondary to Scheuermann's disease. Mean length of follow-up was 16 months. In the scoliosis cases the mean pre-operative Cobb angle of the major curve was 58.6° with a mean correction of 35.6°. The mean post-operative thoracic kyphosis was 21.1°. The median number of levels included in the correction was 13. Bilateral rails were used in four cases, the remainder had one rail on the concave side and a contralateral rod. No patients required an anterior release or staged surgery. All kyphosis cases had posterior apical corrective osteotomies. The mean pre-operative thoracic kyphosis was 75.5° with a mean correction of 31°. The median number of levels included in the correction was 11. Four patients had bilateral rails. No patients required anterior release. Complications: two patients had prominent hardware. One patient had a malpositioned screw causing nerve root irritation, which was removed. There were three superficial infections, which settled with antibiotics. There were no cases of implant breakage, screw pull-out, or loss of correction. The K2M MESA Rail is a powerful new implant design which helps to achieve and maintain satisfactory correction of complex spinal deformity, and is particularly strong at correcting kyphotic deformity. It also enables restoration of normal thoracic kyphosis, particularly in idiopathic thoracic curves, which tend to be lordosing. This may prevent thoracic flat back and potential long-term sequelae. Early results show that the system is as safe and effective as other posterior deformity correction implants on the market, however, it requires further prospective follow-up to ascertain its outcomes in the long-term.
To determine the efficacy and safety of the Magec system in early onset scoliosis (EOS). In 2011, 6 males and 2 females had Magec rods, with an average age of 8.5 years (2.9–12.7 years), 7 patients had dual rods, and 1 had single. The main cause of EOS was idiopathic scoliosis (n=6), followed by Congenital (n=1), and Syndromic (n=1). Average follow up was 19.4 months (14–26 months). 4 of these patients had their previous Paediatric Isola growing rods exchanged to Magec, and 1 patient had an exchange from single to Dual Magec rods.Aim:
Methods:
To measure truncal parameters for patients treated with growing rod systems for early onset scoliosis (EOS). 44 patients underwent growth rod surgery for EOS between 1999 and 2013 (24 females and 20 males). 27 patients had idiopathic scoliosis, 13 congenital, 3 syndromic and 1 neuromuscular. 26 patients had Paediatric Isola, 8 had Paediatric Expedium, 4 had dual growth rods with domino's and 9 each had VEPTR and MAGEC rods systems. Medical records and radiographs were analysed. Cobb angle, T1-T12 and T1-S1 length, coronal and sagittal balance, apical vertical translation (AVT), space available for the lung (SAL) and shoulder balance were measured.Aim:
Methods:
Retrospective review of growth sparing spinal instrumentation. Medical records of 30 children with spinal deformity treated were evaluated. There were 14 male and 16 female patients at an average age of 4.9 years (1-14) at the time of presentation. These included 18 idiopathic, 11 congenital and a 14 year old with delayed growth having GH treatment. All patients underwent dual growing rod construct using hook and pedicle screw instrumentation. Extensions were carried out at approximately 6 monthly intervals. Average follow up was 4.2 years (2-8.5) with an average of 7.3(3-15) extension/exchange procedures per patient. Average immediate postoperative Cobb angle was 29(15-55) from a preoperative Cobb of 68(55-100) and this was maintained to a final mean Cobb angle of 30(15-60). Average gain in T1-S1 length was 5.7(3.5-9.8) cm. Five patients had final fusion at an average age of 15.5 years. There were no infections following primary operation. Out of 249 procedures including extensions/exchange, there were 9(4.5%) episodes of deep infection in 7 patients requiring debridement. Four patients (13%) had revisions for rod breakage/screw loosening/hook pullout/junctional kyphosis and three(10%) had prominent implants.Purpose
Methods and results
To evaluate efficacy of blood conservation strategies on transfusion requirements in adult scoliosis surgery and establish a protocol for cross matching. 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.Purpose
Methods and Results
Spinal cord injury following trauma is initially dealt with by acute hospitals. The early management including stabilization is usually performed by these centres. This is followed by onward referral to one of the Regional Spinal Injury Units. There is concern of both sides of the fence regarding mobilization following spinal cord injury. The acute hospitals want to avoid the problems of prolonged recumbency and the Regional Spinal Injury Units wish to avoid the problems of early aggressive mobilization. Therefore, we set out to discover if there was a standard approach to mobilising these patients following surgical stabilization, because of the oversubscribed resources of the spinal injury units and the wish to start mobilizing the injured as soon as possible. A comparative audit of the Regional Spinal Injury Units in the UK and North American Units. Regional Spinal Injury Units in United Kingdom and North America Clear Management Plan Mobilisation Schedule We had replies from all Regional Spinal Injury Units in the UK and from seven in North America. The Regional Spinal Injury Units all had differing approaches. Only a few were able to convey a clear management plan and mobilization schedule. Whereas the North American Units provided a ‘mobilize as able’ plan in all cases. The North American Units had a ‘mobilize as able’ policy, whereas the UK units had a mixed approach. A coherent collaboration between the spinal surgeons stabilizing these injuries and the spinal injury units providing rehabilitation would improve patient management.
To assess adverse events related to XLIF approach in lumbar degenerative disease. Recently novel minimally disruptive spine procedure eXtreme lateral Interbody Fusion i.e XLIF has been developed. It is 90 (off the midline true lateral approach, which allows large graft placement, excellent disc height restoration and indirect decompression at the stenotic motion segment. We describe our experience in 28 patients. Retrospective review of records of patients undergoing surgery between July 2008- Jan 2010. Presenting complaints, number of levels performed and complications (medical, approach, or implant related) were audited. Results: 28 patients (17 female: 11 male) with median age of 47 yrs, range (38-75) formed the study group. Average stay was 4 days. All patients had MRI of lumbar spine. 2/3 rd patients had low back pain as their presenting complaint. All patients had nerve monitoring through out the procedure. There were 12 single, 15 two level and 1 three level cases (total 45 levels). 14/28 patients underwent plating at the same time. EBL was 100ml. There were 11/45 adverse events (24.4%). 6 events were approach, 4 were implant bone interface and 1 medical related. Major complication occurred in 1 patient (3.6%). 2/3 rd of patients, were better after the surgery. Almost negligible blood loss, low infection rate and short average stay seemed to work in favour of this approach. Complications are there as (with any new procedure) our results indicate, but these are manageable and less common with this technique. This did not require Ethics approval and there was no grant or industry support for the above.
We have examined the outcome in 19 professional rugby union players who underwent anterior cervical discectomy and fusion between 1998 and 2003. Through a retrospective review of the medical records and telephone interviews of all 19 players, we have attempted to determine the likelihood of improvement, return to professional sport and the long-term consequences. We have also attempted to relate the probability of symptoms in the neck and radicular pain in the arm to the position of play. Neck and radicular pain were improved in 17 patients, with 13 returning to rugby, the majority by six months after operation. Of these, 13 returned to their pre-operative standard of play, one to a lower level and five have not played rugby again. Two of those who returned to the game have subsequently suffered further symptoms in the neck, one of whom was obliged to retire. The majority of the players with problems in the neck were front row forwards. A return to playing rugby union after surgery and fusion of the anterior cervical spine is both likely and safe and need not end a career in the game.
