Fracture of the odontoid process (OP) in the elderly is associated with mortality rates similar to those of hip fracture. The aim of this study was to identify variables that predict mortality in patients with a fracture of the OP, and to assess whether established hip fracture scoring systems such as the Nottingham Hip Fracture Score (NHFS) or Sernbo Score might also be used as predictors of mortality in these patients. We conducted a retrospective review of patients aged 65 and over with an acute fracture of the OP from two hospitals. Data collected included demographics, medical history, residence, mobility status, admission blood tests, abbreviated mental test score, presence of other injuries, and head injury. All patients were treated in a semi-rigid cervical orthosis. Univariate and multivariate analysis were undertaken to identify predictors of mortality at 30 days and one year. A total of 82 patients were identified. There were 32 men and 50 women with a mean age of 83.7 years (67 to 100).Aims
Patients and Methods
Centre Hospitalo-Universitaire de Bordeaux, Service de Pathologie du la Colonne Vertébrale, Bordeaux, France. Assessment of cervical lordosis using a standardised digital acquisition procedure in the normal population Three independent reviewers measured static lordosis. The EOS¯ system, which utilises low dose radiation and provides reliable standardized digital 2D acquisition with 3D reconstruction was employed. Measurements were carried out twice by every examiner on two different occasions. Cohort of the general public of 180 subjects divided into 4 groups (both sexes individually, age less than 40 and greater than 50 individually). None had any previous history of spinal disorders or sagittal imbalance. General cervical lordosis (C2 to C7) as well as upper and lower cervical lordosis were assessed. Cervical lordosis in the general population has a very wide range in both sexes. Overall cervical lordosis was 37 degrees. Lower cervical lordosis (superior endplate of C4 to inferior endplate of C7) demonstrated an average of 16 degrees, and upper cervical lordosis was found to be 21 degrees. No particular age group or sex was more prone to having lesser/greater lordosis. Current literature is sparse and provides large ranges, different standards and variable methods for assessing standard cervical lordosis. Overall cervical lordosis is very variable amongst the sexes and age groups. We provide a standard set of values which help to provide the spinal surgeon with values to aim for when seeking to restore cervical lordosis.
Competency levels of AOSpine members (Europe) based on whether or not they had undertaken a full 12 month fellowship in spinal surgery Self-assessment questionnaire distributed to members (60 questions relating to: previous surgical training, fellowships and their nature, and both theoretical and practical competency amongst basic and advanced spinal conditions) 289 completed responses Competency levels with(out) fellowship; differences in fellowship training; overall competence in spinal surgery as neurosurgeons versus those trained as orthopaedic surgeons. Competency defined as those able to deal with complications or able to perform without supervision. 28% (n=80) undertook a full 12 month fellowship Notable differences between groups were identified (fellowship vs no fellowship): spinal deformity (58% vs 26%), cervical trauma (83% vs 59%), cervical stabilisation (78% vs 53%), lumbar and thoracic trauma (85% vs 57%) and anterior surgery (66% vs 41%) and its complications (46% vs 23%). Interestingly of the whole group only 43% were competent in the actual practice of conservative management of spinal conditions. There was no significant difference in theoretical knowledge or practical skills between orthopaedics surgeons and neurosurgeons. Fellowship training is effective, but there are deficiencies in areas. In order to provide a routine and emergency service as a spinal surgeon, competency at relatively common procedures must be reached. Our data demonstrates a lack of uniformity in such competencies, and we believe efforts towards a formal curriculum for spinal training should be embarked upon.
Centre Hospitalo-Universitaire de Lille, Service de Neurochirurgie et Chirurgie du Rachis, Lille, France. Assessment of current thoughts regarding spinal fellowships amongst spinal fellows in the United Kingdom and abroad Qualitative analysis provides rich and contextual detail that cannot be borne out by quantitative research. We undertook detailed interviews amongst fellows who have varying fellowship experience both in the United Kingdom and abroad. Ten fellows, all of whom were approaching their Certificate of Completion of Training (or equivalent) in Trauma and Orthopaedic surgery, or just awarded the certificate. All undertaking/undertaken at least one 12-month fellowship. Qualitative experiences A large unit provides a breadth of pathology that may is usually not encountered in smaller units. Fellows who worked in such units felt confident that they would recognise a variety of pathologies, but did not necessarily feel confident in their surgical management. Operative exposure to deformity surgery, whilst not necessarily a future part of practice, was felt useful for the added technical skills it provides. Fellows attending a smaller unit, where they may have been the sole ‘spinal fellow’, reported greater satisfaction in operative experience. Interestingly, there was felt to be a ‘saturation point’, where a fellow perceived no further educational benefit from remaining in one particular unit. A fellowship in spinal surgery is useful in preparing for independent practice as a spinal surgeon. Large units provide skills that are applicable to several aspects of spinal surgery. There appears to be a difference in breadth and complexity of pathology versus operative experience.
The revised Tokuhashi score has been widely used to evaluate indications for surgery and predict survival in patients with metastatic spinal disease. Our objective was to determine whether the score accurately predicted survival in those with MSCC. Retrospective analysis All patients with MSCC presenting to our unit were included in this study from October 2003 to December 2009. Patients were divided into three groups – Tokuhashi score 0 – 8, 9 – 11 and 12 -15. Neurological outcome and survival A total of 109 patients with MSCC were managed in our unit during this time. Mean age of patients was 61 years (range 7 - 86). Mean and median survival was 350 (5-2256) and 93 days in the 0-8 group, 439 (8-1902) and 229 days in the 9-11 group, and 922 (6-222) and 875 days in the 12-15 group; p = 0.01. All patients underwent decompression and stabilisation surgery. The rate of consistency between the prognostic score and actual survival was 64% (0-8), 64% (9-11) and 69% (12-15). Overall the consistency was 66%. There was no difference in neurological outcome between the 3 groups. There was a significant difference in the mean survival between groups. There was a moderate consistency between predicted and actual survival in this group of patients who all had cord compression. All patients had undergone some form of decompression and stabilisation surgery regardless of the overall revised Tokuhashi score.
To assess whether the timing of surgery is an important factor in neurological outcome in patients with MSCC. Retrospective review All patients with MSCC presenting to our unit were included in this study from October 2003 to December 2009. Patients were divided into three groups - those who underwent surgery within 24 hours (Group 1), those 24 hours to 48 hours (Group 2) and those greater than 48 hours (Group 3). Neurological outcome (improvement in Frankel score), complication rate and survival were assessed in all groups. A total of 109 patients with MSCC were operated on in our unit during this time. Mean age of patients was 61 years (range 7 - 86). The number that had at least one grade of Frankel improvement was 21 /37 (57%) in group 1; 11/17 (65%) in group 2 and 20/49 (41%) in group 3, p=0.03. When patients treated less than 24 hours were compared with those greater than 24 hours, the Frankel grade improvement approached significance (p=0.05). When we compared those who had surgery within 48 hours and those greater than 48 hours, the Frankel grade improvement was highly significant (p=0.009). There was no difference in survival or complications between the groups. Our results suggest that early surgical treatment in patients with MSCC gives a better neurological outcome but has no influence on survival or complication rates.
