Today is the start of chiropractic awareness week 2022. On this occasion the BCA states most categorically: First and foremost, chiropractic is a statutorily regulated healthcare profession, supported by evidence, which offers a safe form of treatment for patients with a range of conditions. Here I am tempted to cite my friend Simon Singh:
I am, of course, particularly impressed by the BCA’s assurance of safety. In my view, the safety issue needs to be addressed more urgently than any other in the realm of chiropractic. So, to make a meaningful contribution to the current chiropractic awareness week, I conducted a few Medline searches to identify all publications of 2022 on chiropractic/spinal manipulation risks.
This is what I found:
Objective: Patients can be at risk of carotid artery dissection and ischemic stroke after cervical chiropractic manipulation. However, such risks are rarely reported and raising awareness can increase the safety of chiropractic manipulations.
Case report: We present two middle-aged patients with carotid artery dissection leading to ischemic stroke after receiving chiropractic manipulation in Foshan, Guangdong Province, China. Both patients had new-onset pain in their necks after receiving chiropractic manipulations. Excess physical force during chiropractic manipulation may present a risk to patients. Patient was administered with recombinant tissue plasminogen activator after radiological diagnoses. They were prescribed 100 mg and clopidogrel 75 mg daily for 3 months as dual antiplatelet therapy. There were no complications over the follow-up period.
Conclusion: These cases suggest that dissection of the carotid artery can occur as the result of chiropractic manipulations. Patients should be diagnosed and treated early to achieve positive outcomes. The safety of chiropractic manipulations should be increased by raising awareness about the potential risks.
Spontaneous intracranial hypotension (SIH) still remains an underdiagnosed etiology of new-onset headache. Important risk factors include chiropractic manipulation (CM). We present a case of a 36-year-old Filipino woman who presented with severe bifrontal and postural headache associated with dizziness, vomiting, and doubling of vision. A cranial computed tomography scan was done which showed an acute subdural hematoma (SDH) at the interhemispheric area. Pain medications were given which afforded minimal relief. On history, the headaches occurred 2 weeks after cervical CM. Cranial and cervical magnetic resonance imaging revealed findings supportive of intracranial hypotension and neck trauma, respectively. The patient improved with conservative management. We found 12 articles on SIH and CM after a systematic review of literature. Eleven patients (90.9%) initially presented with orthostatic headache. Eight patients (66.7%) were initially treated conservatively but only 5 (62.5%) had complete recovery. Recovery was achieved within 14 days from start of supportive therapy. Among the 3 patients who failed conservative treatment, 2 underwent non-directed epidural blood patch and one required neurosurgical intervention. This report highlights that a thorough history is warranted in patients with new onset headache. A history of CM must be actively sought. The limited evidence from the case reports showed that patients with SIH and SDH but with normal neurologic examination and minor spinal pathology can be managed conservatively for less than 2 weeks. This review showed that conservative treatment in a closely monitored environment may be an appropriate first line treatment.
Introduction: Cranio-cervical artery dissection (CeAD) is a common cause of cerebrovascular events in young subjects with no clear treatment strategy established. We evaluated the incidence of major adverse cardiovascular events (MACE) in CeAD patients treated with and without stent placement.
Methods: COMParative effectiveness of treatment options in cervical Artery diSSection (COMPASS) is a single high-volume center observational, retrospective longitudinal registry that enrolled consecutive CeAD patients over a 2-year period. Patients were ≥ 18 years of age with confirmed extra- or intracranial CeAD on imaging. Enrolled participants were followed for 1 year evaluating MACE as the primary endpoint.
Results: One-hundred ten patients were enrolled (age 53 ± 15.9, 56% Caucasian, and 50% male, BMI 28.9 ± 9.2). Grade I, II, III, and IV blunt vascular injury was noted in 16%, 33%, 19%, and 32%, respectively. Predisposing factors were noted in the majority (78%), including sneezing, carrying heavy load, chiropractic manipulation. Stent was placed in 10 (10%) subjects (extracranial carotid n = 9; intracranial carotid n = 1; extracranial vertebral n = 1) at the physician’s discretion along with medical management. Reasons for stent placement were early development of high-grade stenosis or expanding pseudoaneurysm. Stented patients experienced no procedural or in-hospital complications and no MACE between discharge and 1 year follow up. CeAD patients treated with medical management only had 14% MACE at 1 year.
Conclusion: In this single high-volume center cohort of CeAD patients, stenting was found to be beneficial, particularly with development of high-grade stenosis or expanding pseudoaneurysm. These results warrant confirmation by a randomized clinical trial.
Background: Manipulation and mobilisation for low back pain are presented in an evidence-based manner with regard to mechanisms of action, indications, efficacy, cost-effectiveness ratio, user criteria and adverse effects. Terms such as non-specific or specific are replaced by the introduction of “entities” related to possible different low back pain forms.
Efficacy: MM is effective for acute and chronic low back pain in terms of pain relief, recovery of function and relapse prevention. It is equally effective but less risky compared to other recommended therapies. MM can be used alone in acute cases and not only in the case of chronic low back pain where it is always and necessarily part of a multimodal therapy programme, especially in combination with activating measures. The users of MM should exclusively be physician specialists trained according to the criteria of the German Medical Association (Bundesärztekammer) with an additional competence in manual medicine or appropriately trained certified therapists. The application of MM follows all rules of Good Clinical Practice.
Adverse effects: Significant adverse effects of MM for low back pain are reported in the international literature with a frequency of 1 per 50,000 to 1 per 3.7 million applications, i.e. MM for low back pain is practically risk-free and safe if performed according to the rules of the European Training Requirements of the UEMS.
Studies have reported that mild adverse events (AEs) are common after manual therapy and that there is a risk of serious injury. We aimed to assess the safety of Chuna manipulation therapy (CMT), a traditional manual Korean therapy, by analysing AEs in patients who underwent this treatment. Patients who received at least one session of CMT between December 2009 and March 2019 at 14 Korean medicine hospitals were included. Electronic patient charts and internal audit data obtained from situation report logs were retrospectively analysed. All data were reviewed by two researchers. The inter-rater agreement was assessed using the Cohen’s kappa coefficient, and reliability analysis among hospitals was assessed using Cronbach’s Alpha coefficient. In total, 2,682,258 CMT procedures were performed in 289,953 patients during the study period. There were 50 AEs, including worsened pain (n = 29), rib fracture (n = 11), falls during treatment (n = 6), chest pain (n = 2), dizziness (n = 1), and unpleasant feeling (n = 1). The incidence of mild to moderate AEs was 1.83 (95% confidence interval [CI] 1.36-2.39) per 100,000 treatment sessions, and that of severe AEs was 0.04 (95% CI 0.00-0.16) per 100,000 treatment sessions. Thus, AEs of any level of severity were very rare after CMT. Moreover, there were no instances of carotid artery dissection or spinal cord injury, which are the most severe AEs associated with manual therapy in other countries.
This is not too bad after all!
Five papers are clearly better than nothing.
What conclusions might be drawn from my mini-review?
I think it might be safe to say:
Thus, allow me to make a suggestion to chiropractors worldwide: Instead of continuing with HAPPILY PROMOTING BOGUS TREATMENTS, what about using the ‘chiropractic awareness week’ to raise awareness of the urgent necessity to research the safety of your treatments?
