To establish the incidence of litigation in Cauda Equina Syndrome (CES) and the causes of litigation. Review of 10 years of abbreviated records of the National Health Service litigation authority (NHSLA) (1997-2007) and eight years of medical negligence cases (MNC) reported on by the two senior authors (2000-2008). Patients who experienced CES and litigated. There were 117 patients in the NHSLA records and 23 patients in the MNC group. Review of timing of onset, delay in diagnosis, responsible specialist, place, and resulting symptoms. NHSLA cases. 62/117 cases were closed. The responsible specialists were as follows. Orthopaedic. 60. Accident and Emergency. 32. Other. 25. The commonest failure was delay in diagnosis, and the commonest complications were “neurological”, bladder and bowel. MNC cases. F:M;17/6. L4/5 13 cases, L5/S1 9 cases. The responsible specialist was orthopaedic (7), other (7) and in 8 cases the opinion was that there was no case to answer. Delay to treatment averaged 6.14 days. 18/23 patients described bowel and bladder symptoms, the information was not available in the remainder. Litigation is major problem in CES. In most cases orthopaedic surgeons are litigated against, and bowel and bladder symptoms remain the most disturbing cause of litigation. These surgeons are mostly not spinal specialists. In most successful cases of litigation there is considerable delay in diagnosis and management. Where there is incomplete Cauda Equina Syndrome urgent or emergency investigation and treatment is mandatory

Background. Surgical patients have cost the NHS 1.3 billion GBP from 1995. Spinal pathologies can present diagnostic challenges, and the consequences of delayed diagnosis or surgical complications can be devastating and so creating high indemnity costs. We aim to highlight the spinal associated litigation patterns within the United Kingdom. Method. Data was obtained from the NHS Litigation Authority from 2002 to 2010. Result. From 236 claims, 144 were related to trauma or acute diagnostic issues and 92 from elective surgery. The financial burden to the NHS came to 60.5 million GBP. Of this sum 42.8 million GBP were paid in damages, and the remaining 29% in legal costs. The financial costs were similar for trauma and elective cases. The most frequent cause of successful litigation for trauma were, missed fractures(41.7%), missed cauda equina(23.6%) and spinal infection(11.8%). The emergency department(43.8%), orthopaedic surgery(28.5%) and Medicine(13.9%) bore the brunt of the claims. For elective surgery, Spinal Damage(19.8%), failure in Post-Operative Care(15.4%), Infection(11%) and Wrong Level Surgery, Cauda Equina and Surgical Failure(9.9% each). were likely to result in a successful claim, and the litigation burden was felt by the orthopaedic(60.4%), Neurosurgery(18.7%) and other surgical disciplines(11%). Conclusion. Acute spinal fractures, cord compression and infection should be considered in patients in the emergency department setting, with appropriate examination and investigations for uncertainty. A lack of awareness of at risk cases increases the likelihood of a pay-out and sums involved. For elective spinal surgery, a failure in the consenting process and the technical skill of the surgeon are likely to result in a pay-out. A failure to identify post-operative complications such as infection and thromboembolism are also indefensible. Protecting patients intra-operatively and maintaining high technical expertise and vigilance post-operatively in an adequately consented patient may decrease litigation rates

The aim of this study was to review the data held with the NHSLA database over the last 10 years for negligence in spine surgery with particular focus on why patients ‘claim’ and what is the likely outcome.

Anonymous retrospective review

We contacted the NHSLA and asked them to provide all data held on their database under the search terms ‘spine surgery or spine surgeon.’

An excel sheet was provided, and this was then studied for reason of ‘claim’, whether the claim was open/closed and outcome.

A total of 67 claims of negligence were made against spinal surgeries during this time (2000-09). The number of claims had increased over the last few years: 2000-03, n= 8, 2004-06, n= 46. The lumbar spine remains the most common area (Lumbar: 55/67, Thoracic : 6/67, Cervical 6/67). Documented reasons for claims were post-operative complications (n= 28; 42%), delayed/failure to diagnose (n=24; 36%), discontent with preoperative assessment including consent (n=2; 3%), intra-operative complications (n= 10; 15%) and anaesthesia complication (n=3; 4%).

Twenty were closed and 47 remained open. The number of successful claims was 8/20 (40%). The mean compensation paid out was £33,409 (range was £820.5 to £60,693).

The number of claims brought against spinal surgeries is on the increase, with the most common area being the lumbar spine which perhaps is not surprising as this is the most common area of spinal surgery. Common reasons are post-operative complications and delay/failure to diagnose. The ‘success’ of these claims over the last 10 years was 8/20 (40%) with mean compensation paid out was £33,409.

Whiplash injury is surrounded by controversy in both the medical and legal world. The debate on whether it is either a potentially serious medical condition or a social problem is ongoing. This paper briefly examines a selection of studies on low velocity whiplash injury (LVWI) and whiplash associated disorder (WAD) and touches upon the pathophysiological and epidemiological considerations, cultural and geographical differences and the effect of litigation on chronicity. The study concludes that the evidence for significant physical injury after LVWI is poor, and if significant disability is present after such injury, it will have to be explained in terms of psychosocial factors

Background. Being involved in litigation is associated with poor outcomes, higher levels of pain, disability, catastrophising, fear-avoidance and other psychological factors. Poor access to treatments can contribute to chronicity of symptoms and poor outcomes, especially in patients involved in litigation with a longer time since the accident. Purpose. To examine the relationship between time since the accident, access to treatments and current psychological variables. Methods. Eleven patients completed the Pain Catastrophising Scale, Tampa Scale for Kinesiophobia, Zung Depression Inventory, Modified Somatic Perceptions Questionnaire as well as details about the accident, working status and recalled access to treatments. The results were analysed qualitatively and quantitavely. Results. The mean time since the accident was 32 months and the mean measures are: ZDI (41.9±9.3), PCS (33.3±9.4), TSK (47.5±9.2), MSPQ (15±8.4). Eight subjects are not currently working and three are working part-time. There was a positive correlation between time since the accident and depression (r=0.679) and MSPQ (r=0.547) but not for other variables. Average sequence of recalled treatments is outlined. Conclusion. Our results indicate that measures of depression and somatic perceptions keep increasing with time whereas catastrophising and kineshiophobia are relatively constant in a small group of litigants with spinal pain. The recalled treatments reflect a focus on invasive treatments with little long-term positive outcome and only one patient receiving the recommended combined physical and psychological programme. I can confirm that this abstract has not previously been published in whole or substantial part nor has it been presented previously at a national meeting.

We assessed the frequency and causes of neurological deterioration in 59 patients with spinal cord injury on whom reports were prepared for clinical negligence litigation. In those who deteriorated neurologically we assessed the causes of the change in neurology and whether that neurological deterioration was potentially preventable. In all 27 patients (46%) changed neurologically, 20 patients (74% of those who deteriorated) had no primary neurological deficit. Of those who deteriorated, 13 (48%) became Frankel A. Neurological deterioration occurred in 23 of 38 patients (61%) with unstable fractures and/or dislocations; all 23 patients probably deteriorated either because of failures to immobilise the spine or because of inappropriate removal of spinal immobilisation. Of the 27 patients who altered neurologically, neurological deterioration was, probably, avoidable in 25 (excess movement in 23 patients with unstable injuries, failure to evacuate an epidural haematoma in one patient and over-distraction following manipulation of the cervical spine in one patient). If existing guidelines and standards for the management of actual or potential spinal cord injury had been followed, neurological deterioration would have been prevented in 25 of the 27 patients (93%) who experienced a deterioration in their neurological status.

Introduction. Lumbar spinal pain can be a consequence of discogenic pain. After failure of conservative management, lumbar fusions are popular and considered the gold standard. However, these techniques are associated with significant morbidity. A percutaneous trans-sacral technique may address these for L4/L5 and/or L5/S1 alone spinal fusions. Our unit has adopted this technique and presents our initial experience of 51 patients and preliminary results. Method. Patients with a confirmed clinical and radiological evidence of degenerate intervertebral disc with or without prior surgical intervention were selected. Patients with a history of pelvic surgery/radiotherapy were excluded. Data was collected prospectively using the Global Patient Outcome Scoring System and Oswestry Disability Index (ODI) scores at clinical follow-up. Results. 51 patients received the procedure and 30 achieving a minimum of 6 months follow-up. Patients had a median age of 46(range 20-78) and included 19 male and 32 females with on average 40 months of pain. The mean ODI score improved after surgery from pre-operative levels 52.9(SEM 3.0) to 6 month scores of 38.4(SEM 3.9), t(29)=4.2, p<0.0002 . This difference remained statistically significant at 12 month follow-up with a mean ODI scores 34.3 (SEM 5.2), t(18)=4.37, P<0.0004 (Mean difference of 21.1 SEM 4.8). A sub-analysis of confounding factors identified patients with previous surgery, claiming state benefits, pursuing litigation, mainly leg pain and requiring pedicular fusion failed to achieve statistical significance. Patients receiving a 360 degree fusion with facet screws alone improved sooner and achieving a mean difference in ODI score of 27.6(SEM 8.2). Conclusion. Our initial results confirm this to be an effective alternative treatment modality for lumbar spine fusion in the management of primary discogenic back pain. Patients receiving 360 degree fusion and not claiming state benefits or pursuing litigation appear to have a better outcome

Aims

Cauda equina syndrome (CES) can be associated with chronic severe lower back pain and long-term autonomic dysfunction. This study assesses the recently defined core outcome set for CES in a cohort of patients using validated questionnaires.

Methods

Between January 2005 and December 2019, 82 patients underwent surgical decompression for acute CES secondary to massive lumbar disc prolapse at our hospital. After review of their records, patients were included if they presented with the clinical and radiological features of CES, then classified as CES incomplete (CESI) or with painless urinary retention (CESR) in accordance with guidelines published by the British Association of Spinal Surgeons. Patients provided written consent and completed a series of questionnaires.

We have examined how many and which potential complications (PCs) are recorded on the consent form by a group of consultant surgeons performing common spinal procedures - anterior cervical discectomy and fusion (ACDF) and posterior lumbar discectomy and/or medial facetectomy (PLD). Email survey. Consultant spinal surgeons performing ACDF and/or PLD practicing in Southwest England. Identification of the PCs each surgeon listed on the consent form for the specified procedures. There were 23 responses from 28 Consultant surgeons approached. 21 surgeons performed both ACDF and PLD, 2 performed only PLD. Surgeons quoted 5 to 17 (mode 10) PCs for ACDF and 4 to 15 (mode 13) for PLD. These did not necessarily represent the most common or most dangerous PCs recorded in the literature. 1,2. Small difference in PCs mentioned by Neurosurgeons and Orthopaedic surgeons was seen (ACDF mode: 12vs10, PLD mode: 12vs13). There was a strong correlation between the number of PCs recorded by surgeons for ACDF and PLD. We have found a wide variation in consenting practice amongst a group of surgeons performing common spinal operations. Issues of consent are common causes of formal complaints and potential litigation, causing anxiety for both patient and surgeon. A more homogenous consent process, employing objective measures where possible, may help reduce this burden and may be achieved by setting a national standard

Objectives. To assess health care professional's knowledge with regards to the urinary symptoms of CES and when treatment should be offered. Background. Recent articles in the medical press highlight the potential dangers of Cauda Equina Syndrome (CES). CES has the highest rates of litigation due to its long-term neurological impairment. Method. A 4-part questionnaire was given to 60 professionals. The participant was asked to rank 15 urinary symptoms, 7 of these symptoms were not related to CES, also the ideal time to surgical intervention for Complete CES and Incomplete CES. Results. A total of 44 questionnaires were analysed. CES symptoms were ranked significantly higher than then non-CES symptoms. The physiotherapists rated the CES symptoms significantly higher than the doctors (P = 0.05) and on average rated the non-CES symptoms significantly lower than doctors (P < 0.05). 87.8% thought that complete CES should be treated < 24 hours and 9.76% thought that complete CES should be treated from 24-48 hours. 46.34% thought that CESI should be treated < 24 hours and 43.9% thought that CESI should be treated from 24-48 hours. Conclusion. These results demonstrate that physiotherapists are better than Doctors at identifying the urinary symptoms in CES. The majority of health care professional who took part in this study stated that they would offer surgical intervention for both Complete and Incomplete CES within 24 hours. The gap in knowledge highlights the need for education to all medical professionals in the symptoms of CES and also the timing of treatment

Coccygectomy is a controversial operation. Some authors have reported good results, but others advise against the procedure. The criteria for selection are ill-defined. We describe a study to validate an objective criterion for patient selection, namely radiological instability of the coccyx as judged by intermittent subluxation or hypermobility seen on lateral dynamic radiographs when sitting. We enrolled prospectively 37 patients with chronic pain because of coccygeal instability unrelieved by conservative treatment who were not involved in litigation. The operation was performed by the same surgeon. Patients were followed up for a minimum of two years after coccygectomy, with independent assessment at two years. There were 23 excellent, 11 good and three poor results. The mean time to definitive improvement was four to eight months. Coccygectomy gave good results in this group of patients

To assess health care professionals knowledge with regards to urinary symptoms of CES and when treatment should be offered. A 4-part questionnaire established profession and number of cases seen per week. The participant was asked to rank 15 urinary symptoms, 7 of these symptoms were not related to CES. The participants were asked the ideal time to surgical intervention for Complete CES and Incomplete CES. Primary and Secondary Care. 60 questionnaires were complete. Participants had to successfully complete the first three parts of the questionnaire (n = 44). Any who failed to complete section four were excluded from analysis from that part only (n = 41). A total of 44 questionnaires were analysed. Both doctors and physiotherapists ranked the CES symptoms on average significantly higher than then the non-CES symptoms. The physiotherapists rated the CES symptoms significantly higher than the doctors (P = 0.05) and on average rated the non-CES symptoms significantly lower than doctors (P < 0.05). 87.8% thought that complete CES should be treated < 24 hours and 9.76% thought that complete CES should be treated from 24-48 hours. 46.34% thought that CESI should be treated < 24 hours and 43.9% thought that CESI should be treated from 24-48 hours.

Purpose. To determine, for the first time, how back pain is portrayed in the United Kingdom press. Methods and Results. LexisNexisTM Professional search engine was utilised to retrieve articles from all national newspapers over a six months containing the terms “back pain/backpain/back ache/backache” from May to October 2009. 284 relevant articles were retrieved. Of these tabloids accounted for 62% and broadsheets for 38%. Back pain was the sole topic in 7%, a main topic in 18% and mentioned in passing in 75%. 15% were essentially case reports and the tone was neutral in 95%, positive in 2.5% and negative in 2.5%. The cause of back pain was mentioned in 11% of articles- trauma accounted for 50% and disc disease and spinal deformity for 20% each. Only 0.3% of articles discussed litigation. Articles mentioned new physiotherapy regimes in 7%, new forms of alternative therapy in 7%, new surgical techniques/technologies in 2% and new medications in 1%. They were significantly more likely to mention new non-surgical techniques- Fishers' Exact Test p=0.01. Articles were alternative therapy related in 3%, physiotherapist related in 2%, surgeon related in 1% and pain specialist related in 1%. 10% of papers included a quote from an “expert” of which 23% were Spine Surgeons, 16% GP's, 13% Sports Physicians, 13% alternative therapists, 10% pain specialists and 7% physiotherapists. Overall, 98% of articles were of a neutral tone and 1% were of a positive tone or negative tone. Articles concerning physiotherapists or new surgical techniques/technologies were significantly more likely to be of a positive overall tone than the other articles- Fishers' Exact Test p=0.04. Conclusions. Back pain receives a considerable amount of attention in the United Kingdom press. Much of this currently concentrates on isolated case reports, the aetiology of back pain is poorly represented, quoted “experts” are frequently non-medical and new surgical treatments receive significantly less attention than new non-surgical treatments. The press play an important role in educating and informing the general public. The stories they cover ad how they cover them have a powerful influence on public perceptions. We need to do more to engage with the press and positively influence their reportage

Aims

Diagnosis of cauda equina syndrome (CES) remains difficult; clinical assessment has low accuracy in reliably predicting MRI compression of the cauda equina (CE). This prospective study tests the usefulness of ultrasound bladder scans as an adjunct for diagnosing CES.

Methods

A total of 260 patients with suspected CES were referred to a tertiary spinal unit over a 16-month period. All were assessed by Board-eligible spinal surgeons and had transabdominal ultrasound bladder scans for pre- and post-voiding residual (PVR) volume measurements before lumbosacral MRI.

Objectives

Loss of motion following spine segment fusion results in increased strain in the adjacent motion segments. However, to date, studies on the biomechanics of the cervical spine have not assessed the role of coupled motions in the lumbar spine. Accordingly, we investigated the biomechanics of the cervical spine following cervical fusion and lumbar fusion during simulated whiplash using a whole-human finite element (FE) model to simulate coupled motions of the spine.

Methods

A previously validated FE model of the human body in the driver-occupant position was used to investigate cervical hyperextension injury. The cervical spine was subjected to simulated whiplash exposure in accordance with Euro NCAP (the European New Car Assessment Programme) testing using the whole human FE model. The coupled motions between the cervical spine and lumbar spine were assessed by evaluating the biomechanical effects of simulated cervical fusion and lumbar fusion.

The belief that an intervertebral disc must degenerate before it can herniate has clinical and medicolegal significance, but lacks scientific validity. We hypothesised that tissue changes in herniated discs differ from those in discs that degenerate without herniation. Tissues were obtained at surgery from 21 herniated discs and 11 non-herniated discs of similar degeneration as assessed by the Pfirrmann grade. Thin sections were graded histologically, and certain features were quantified using immunofluorescence combined with confocal microscopy and image analysis. Herniated and degenerated tissues were compared separately for each tissue type: nucleus, inner annulus and outer annulus.

Herniated tissues showed significantly greater proteoglycan loss (outer annulus), neovascularisation (annulus), innervation (annulus), cellularity/inflammation (annulus) and expression of matrix-degrading enzymes (inner annulus) than degenerated discs. No significant differences were seen in the nucleus tissue from herniated and degenerated discs. Degenerative changes start in the nucleus, so it seems unlikely that advanced degeneration caused herniation in 21 of these 32 discs. On the contrary, specific changes in the annulus can be interpreted as the consequences of herniation, when disruption allows local swelling, proteoglycan loss, and the ingrowth of blood vessels, nerves and inflammatory cells.

In conclusion, it should not be assumed that degenerative changes always precede disc herniation.

Between March 2000 and February 2006, we carried out a prospective study of 100 patients with a low-grade isthmic spondylolisthesis (Meyerding grade II or below), who were randomised to receive a single-level and instrumented posterior lumbar interbody fusion with either one or two cages. The minimum follow-up was for two years. At this stage 91 patients were available for review. A total of 47 patients received one cage (group 1) and 44 two cages (group 2). The clinical and radiological outcomes of the two groups were compared.

There were no significant differences between the two groups in terms of post-operative pain, Oswestry Disability Score, clinical results, complication rate, percentage of post-operative slip, anterior fusion rate or posterior fusion rate. On the other hand, the mean operating time was 144 minutes (100 to 240) for patients in group 1 and 167 minutes (110 to 270) for those in group 2 (p = 0.0002). The mean blood loss up to the end of the first post-operative day was 756 ml (510 to 1440) in group 1 and 817 ml (620 to 1730) in group 2 (p < 0.0001).

Our results suggest that an instrumented posterior lumbar interbody fusion performed with either one or two cages in addition to a bone graft around the cage has a low rate of complications and a high fusion rate. The clinical outcomes were good in most cases, regardless of whether one or two cages had been used.
