Deep vein thrombosis (DVT) has been the subject of considerable media attention after a number of deaths and scares in apparently low risk individuals following long haul flights. While many contributory factors have been put forward for the development of DVT, few cases have been reported following muscle strain. The recent publicity surrounding the calf strain sustained by Steve Waugh, the Australian cricket captain, during the Ashes series was initially unremarkable. The case was however, subsequently complicated by the development of DVT following his return (long haul) flight to Australia. Latest reports indicate that following anticoagulant treatment he has made a full recovery and returned to playing. This case could easily be dismissed as a ‘one off’ or an unusual set of circumstances. The following case report illustrates that DVT following calf strain is by no means unique. The ramifications of these cases may have serious implications for Physicians and manual therapists working in sports medicine.
