Three hundred and five patients (164 males and 141 females) with mean age 39.9 with standard deviation 7.3 and a range of 29-78 years were involved in a study to find out the relationship between load carrying on the head and cervical spondylosis. Out of 225 patients who carried loads on their head, 143 (63.6%) had cervical spondylosis, and of the 80 people who did not carry load on their head, 29 (36%) had cervical spondylosis. 131 (58%) of those who carried load did so regularly with an average weight of about 15 kg or more over a period 10-15 years or more. It is concluded that cervical spondylosis is not exclusively an ageing phenomenon, but that regular heavy load carrying on the head plays an aetiological role.
