Axis Fractures in Elderly : Epidemiology and Treatment related outcome
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Axis fractures are a common injury in the elderly population. Treatment is often complicated due to osteoporosis and patient comorbidity. Knowledge of the incidence of these fractures, as well as their treatment, outcome and mortality rate, will improve knowledge and decision-making processes for this fragile group of patients.Objectives: This thesis aims (1) to review the literature on the non-surgical and surgical treatment of odontoid fractures type 2 in the elderly population, (2) to provide an updated overview of axis fracture subtypes, their incidence and their treatment in a cohort in two university cities, (3) to map the incidence of fractures and the treatment of these patients in Sweden, (4) to investigate the effect on mortality of both the surgical and non-surgical treatment of axis fractures and (5) to present the protocol for a randomized controlled trial (RCT) on the treatment of odontoid fractures type 2 in the elderly population.Methods: A systematic review was performed using the MeSH keywords “odontoid AND fracture AND elderly”. The data for the cohort study were extracted from the regional hospital information system. The radiographs were reviewed retrospectively. Data were extracted from the Swedish National Patient Registry (NPR) and the mortality registry for the national registry studies. Finally, the RCT protocol was carried out according to the SPIRIT and CONSORT statements for clinical trial reporting.Results and conclusions: So far, there has been a scarcity of existing evidence on treatment of odontoid fractures type 2 in the elderly population. In this thesis, we found in two university cities an increased incidence, and a trend towards more surgical treatment of type 2 and 3 odontoid fractures 2002-2014. Between 1997 and 2014 in Sweden, there was an increasing incidence of C2 fractures, but the treatment trend went towards more non-surgical treatment. Surgically treated patients had a greater survival rate than non-surgically treated patients. Among those over 88 years of age, surgical treatment lost its effect on survival. In the RCT we will study the function of patients with odontoid fractures type 2 and by comparing non-surgical treatment with posterior C1-C2 fusion, the cost-effectiveness of the treatment options.

- The currently available data on the distribution of C2 fracture subtypes is sparse. This study was designed to identify the proportions of the second cervical vertebra (C2) fracture subtypes and to present age and gender specific incidences of subgroups. A dataset of all patients treated between 2002 and 2014 for C2 fractures was extracted from the regional hospital information system. C2 fractures were classified into odontoid fractures types 1, 2, and 3, Hangman's fractures types 1, 2, and 3, and atypical C2 fractures. 233 patients (female 51%, age 72 +/- 19 years) were treated for a C2 fracture. Odontoid fractures were found in 183 patients, of which 2 were type 1, 127 type 2, and 54 type 3, while 26 of C2 fractures were Hangman's fractures and 24 were atypical C2 fractures. In the geriatric subgroup 89% of all C2 fractures were odontoid, of which 71% were type 2 and 29% type 3. There was an increasing incidence of odontoid fractures types 2 and 3 from 2002 to 2014. 40% of C2 fractures were treated surgically. This study presents reliable subset proportions of C2 fractures in a prospectively collected regional cohort. Knowledge of these proportions facilitates future epidemiological studies of C2 fractures.

- Objective. C2 fractures are a common injury in the elderly population. Treatment is often complicated due to osteoporosis and patient comorbidity. This study aims to investigate the incidence and treatment trend of C2 fractures in Sweden. Methods. Patients with the principal and secondary diagnosis of fracture of the second vertebrae (ICD-10: S12.1) between 1997 and 2014 were identified in the Swedish National Patient Registry (NPR). Results. Between 1997 and 2014, 6,370 patients with a C2 fracture (51% male; age: ) were identified in the NPR. The incidence of C2 fractures increased from 3 to 6 per 100,000 (; ), mainly due to an increase of incidence in the geriatric subgroup (≥70 years). The percentage of surgically treated patients decreased from 1997 to 2014 (; ). Younger age, male gender, spinal cord injury, and earlier year of admission were associated with surgical treatment assignment.Discussion. This study documents a rising incidence of C2 fractures in the elderly during the last two decades in Sweden. Greater awareness of fractures, improved diagnostics, coding, and a higher activity level of the patients are plausible causes. The declining trend of surgical treatment warrants further study.

- Background ContextFractures of the axis (C2) are the most common cervical spinal injuries in the elderly population. Several authors have reported improved survival among elderly patients with C2 fractures when treated surgically.PurposeWe aimed to analyze whether surgery improves survival of elderly with C2 fractures.Study Design/SettingAn observational population-based longitudinal multi-registry study was carried out.Patient SampleSwedish Patient Registry 1997 to 2014 and Swedish Cause of Death Registry 1997 to 2014 served as source of patient sample.Outcome measuresSurvival after C2 fracture according to non-surgical and surgical treatment was the outcome measure.MethodsWe included all patients treated for the primary diagnosis of C2 fracture (10th revision of the International Statistical Classification of Diseases and Related Health Problems or ICD-10: S12.1) at an age ≥70 years and receiving treatment at a health-care facility. Non-surgical treatment comprises cervical collar or halo-vest treatment. Surgical treatment was identified in the Swedish patient registry extract using the Swedish classification of procedural codes. Survival was determined using the Kaplan-Meier method. Comorbidity was determined using the Charlson Comorbidity Index.ResultsOf the included 3,375 elderly patients with C2 fractures (43% men, aged 83±7 years), 22% were treated surgically. Surgical treatment was assigned based on age, gender, and year of treatment. The 1-year survival of 2,618 non-surgically treated patients was 72% (n=1,856), and 81% (n=614) for the 757 surgically treated (p<.001, relative risk reduction=11%). Adjusted for age, gender, comorbidity, and year of injury, surgically treated patients had greater survival than non-surgically treated patients (hazard ratio=0.88, 95% confidence interval: 0.79–0.97). Among those above 88 years of age (95% confidence interval: 85–92), surgical treatment lost its effect on survival.ConclusionsDespite the frailty of elderly patients, the morbidity of cervical external immobilization with a rigid collar seemingly weighs greater than surgical morbidity, even in octogenarians. For those above 88 years of age, non-surgical treatment should be primarily attempted.

Surgical vs. non-surgical management of displaced type-2 odontoid fractures in patients aged 75 years and older : study protocol for a randomised controlled trial
- 2018

Ingår i: Trials. - : BMC. - 1745-6215. ; 19

Tidskriftsartikel (refereegranskat)abstract
- Background: Displaced odontoid fractures in the elderly are treated non-surgically with a cervical collar or surgically with C1-C2 fusion. Due to the paucity of evidence, the treatment decision is often left to the discretion of the expert surgeon.Methods: The Uppsala Study on Odontoid Fracture Treatment (USOFT) is a multicentre, open-label, randomised controlled superiority trial evaluating the clinical superiority of the surgical treatment of type-2 odontoid fractures, with a 1-year Neck Disability Index (NDI) as the primary endpoint. Fifty consecutive patients aged >= 75 years, with displaced type-2 odontoid fracture, are randomised to non-surgical or surgical treatment. Excluded are patients with an American Society of Anaesthesiologists (ASA) score >= 4, dementia nursing care or anatomical cervical anomalies. The minimal clinically important difference of the NDI is 3.5 points. A minimum of 16 patients are needed in each group to test the superiority with 80% power. By considering a 1-year mortality forecast of 29%, up to 25 participants are recruited in each group. The non-surgical group is fitted with a rigid cervical collar for 12 weeks. The surgical group is treated with a posterior C1-C2 fusion. All participants are monitored with regard to the NDI, EuroQol score (EQ-5D), socio-demographics and computed tomography (CT) at the time of injury, at 6 weeks, 3 months and 12 months. At 12 months, a dynamic radiographical investigation of upper cervical stability is performed. The secondary endpoints are: EQ-5D score, activities of daily living (ADL), bony union, upper cervical stability and mortality.Discussion: USOFT is the first randomised controlled trial comparing non-surgical and surgical management of type-2 odontoid fractures in the elderly. Using the NDI and EQ-5D as endpoints, future value-based decisions may consider quality-adjusted life years gained. Major limitations are (1) the allocation bias of the open-label study design, (2) that only higher training levels of all core specialties of spine surgery are included in the surgical treatment arm and (3) that only one type of surgical stabilisation is investigated (posterior C1-C2 fusion), while other methods are not included in this study.

Tidskriftsartikel (refereegranskat)abstract
- STUDY DESIGN: Prospective cohort study.OBJECTIVE: This study investigates the results of long posterior instrumentation with regard to complications and survival.SUMMARY OF BACKGROUND DATA: Fractures of the cervical spine and the cervicothoracic junction related to ankylosing spinal disease (ASD) endanger both sagittal profile and spinal cord. Both anterior and posterior stabilization methods are well established, and clear treatment guidelines are missing.METHODS: Forty-one consecutive patients with fractures of the cervicothoracic junction related to ASD were treated by posterior instrumentation. All patients were followed prospectively for 2 years using a standardized protocol.RESULTS: Five patients experienced postoperative infections, 3 patients experienced postoperative pneumonia, 2 patients required postoperative tracheostomy, and 1 patient had postoperative cerebrospinal fluid leakage due to accidental durotomy. No patient required reoperation due to implant failure or nonunion. Mean survival was 52 months (95% confidence interval: 42-62 mo). Survival was affected by patient age, sex, smoking, and spinal cord injury.CONCLUSION: Patients with ASD experiencing a fracture of the cervicothoracic region are at high risk of developing complications. The posterior instrumentation of cervical spinal fractures related to ASD is recommended due to biomechanical superiority. Level of Evidence: 4.

Forskningsöversikt (refereegranskat)abstract
- Odontoid fractures type II according to Anderson and d’Alonzo are not uncommon in the elderly patients. Still, due to the paucity of evidence the published treatment guidelines are far from equivocal. This systematic review focuses on the published results of type II odontoid fracture treatment in the elderly with regard to survival, nonunion, and complications. After a systematic literature research 38 publications were included. A cumulative analysis of 1284 published cases found greater survival if elderly patients with odontoid fractures type II received surgical treatment (RR = 0.64). With regard to nonunion in 669 published cases primary posterior fusion had the best fusion results. The systematic literature review came to the following conclusions. (1) Surgical stabilisation of odontoid fractures type II improves survival in patients between 65 and 85 years of age compared to nonsurgical treatment. (2) Posterior atlantoaxial fusion for odontoid fractures type II in the elderly has the greatest bony union rate. (3) Odontoid nonunion is not associated with worse clinical or functional results in the elderly. (4) The complication rate of nonsurgical treatment is similar to the complication rate of surgical treatment of odontoid fractures type II in the elderly.

Supporting the Frontlines: A Scoping Review Addressing the Health Challenges of Military Personnel and Veterans
- 2023
-
Ingår i: Healthcare (Switzerland). - 2227-9032. ; 11:12
-
Tidskriftsartikel (refereegranskat)abstract
- (1) Background: Military personnel and veterans meet unique health challenges that stem from the complex interplay of their service experiences, the nature of warfare, and their interactions with both military and civilian healthcare systems. This study aims to examine the myriad of injuries and medical conditions specific to this population, encompassing physical and psychological traumas. (2) Methods: A scoping review (systematic search and non-systematic review) was performed to evaluate the current landscape of military healthcare. (3) Results: A significant change in the injury profile over time is identified, linked to shifts in combat strategies and the integration of advanced technologies in warfare. Environmental exposures to diverse chemical or natural agents further complicate the health of service members. Additionally, the stressors they face, ranging from routine stress to traumatic experiences, lead to various mental health challenges. A major concern is the gap in healthcare accessibility and quality, worsened by challenges in the civilian healthcare system’s capacity to address these unique needs and the military healthcare system’s limitations. (4) Conclusions: This review underscores the need for holistic, integrated approaches to care, rigorous research, and targeted interventions to better serve the health needs of military personnel and veterans.
