Spinal manipulation has regularly been associated with serious complications, most commonly strokes due to arterial dissections. But there are several other possibilities as well.
A new and unusual case report a serious complication after spinal manipulation has just been published:
A 54-year-old Indian gentleman, presented to hospital with exertional dyspnoea and chest heaviness for the past 6 months which had increased in the last 6 days. Dyspnoea increased on lying down. He was diagnosed as pneumonia on the basis of X-ray and chest CT scan, received treatment for the same and responded to the therapy.
However, breathlessness and hypercapnia persisted. He had unexplained hypercapnia for which extensive investigations were carried out. Neurological and cardiac assessments were essentially normal. On revisit clinical examination, he was found to have paradoxical diaphragmatic movement with respiration. Ultrasound of chest detected no diaphragmatic movement. Detailed history elicited that patient was fond of neck massage and neck cracking wherein his barber would bend his neck with jerk to either side after a haircut.
After considering all possible aetiologies, the authors concluded that this was a case of diaphragm palsy induced by barber neck manipulation, leading to Type-2 respiratory failure. The fact that the vital clues to the diagnosis were elicited by detailed history and thorough examination reinforces that history and clinical examination for doctors shall remain a very important tool for clinical diagnosis.
My chiropractor friends will be relieved, no doubt, to read that, in this incident, a barber rather than a chiropractor caused this unusual incident. Putting my tongue slightly in the direction of my cheek, the story shows me one thing: one does not necessarily have to be a graduate of a chiro-school to cause severe complications with neck manipulations. Occasionally, osteopaths, physiotherapists, doctors and even barbers are capable of the same feast.
