Jeremy Laurance: Blood spinning – legal but controversial
Tottenham have used the method to speed up the return of Jermain Defoe
Jeremy Laurance is a writer on health issues. He is former health editor of The Independent and the i and has covered the specialism for more than 20 years. He thinks the harm medicine does is under-appreciated, the harm it prevents over-rated, and that cycling works better than most drugs. He was named Specialist Journalist of the Year in the 2011 British Press Awards.

Blood spinning is a recognised, though still controversial, technique for speeding up healing both in conventional medicine and in sports medicine.
It is legal – the controversy comes because there is dispute about its effectiveness.
It is used by some specialists in orthopaedic surgery to help with the repair of tendon injuries. It has also been used in cosmetic surgery and urology as well as by athletes such as footballers, most notably at Chelsea.
The technique involves taking a sample of the athlete's blood and spinning it in a centrifuge to increase the concentration of platelets, the constituents of the blood that promote clotting and assist the healing process.
Blood typically contains six per cent platelets but the spinning process can increase that fourfold. Platelets contain growth factors which aid healing.
Platelet-rich plasma injections – the technical name for the process – have been used to treat many musculo-skeletal injuries, including those of tendons, muscles and joints. Typically two or more injections are needed, between four and six weeks apart, but this may vary on the injury.
Professor Angus Wallace, an orthopaedic surgeon specialising in sports medicine and chair of the appeals committee of the Faculty of Sport and Exercise Medicine, said: "It may work but the evidence in support of it is controversial. It is done in orthopaedics to speed healing of torn tendons in the shoulder.
"It should provide a short-term gain and there is little risk of long-term problems. If it doesn't work the athlete will not be fit to play because they will still be in pain."
Blood spinning is not to be confused with blood doping, the technique used by Lance Armstrong, among others, to boost endurance during the Tour de France, which is illegal.
Blood doping involves removing a half-litre of blood from the athlete a month before a race, waiting for the body to regenerate the lost red blood cells and re-infusing the initial blood 24 hours in advance to provide extra oxygen-carrying capacity.
So platelet-rich injections boost healing – possibly – and not performance.
