Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.
Your note (BMJ 2019; 364:1792) is apt. Technical advances move the horizons of the discipline of orthopedics in space and time. It is fast. Salutary indeed!
The human skeletal system is soft and malleable at infancy while it is hard and brittle in old age. From the open pulsating cranial fontanelles at birth to the painful gouty toes at advanced age, our bodies are mostly bone. What a challenge to orthopedics indeed!
My geriatric mind wanders while exposed to the morning tropical solar radiation which manufactures freely vitamin D - the basic ingredient maintaining bone health - and simultaneously gathering ''world news'' (with cricket scores), thus maintaining electrically active the remaining neocortical cells responsible for mental health.
