Background: Injuries to ankle joint consist 12% of visits to emergency departments. In spite of the common occurrence of ankle sprain, syndesmosis injuries are rare, but very debilitating and frequently misdiagnosed. Methods: Among 100 patients with ankle sprain we evaluated the incidence of syndesmosis sprain by MRI of the ankle. Adults who had acute ankle sprain with no fracture and examined on the same day that injury had took place were being included in the survey. Results: Out of 100 patients with ankle injury, four had syndesmosis sprain. Three patients had partial tear of syndesmotic complex and one had complete tear. All injuries occurred in sports except one which had happened in an accident, and two of the patients were athletes. Anterior inferior tibiofibular ligament was the most common ruptured ligament. Conclusions: We reported a four-percent incidence of this injury. Our high rate of this injury emphasized on the fact that all suspicious cases should go under more accurate investigation not to miss this diagnosis

The Royal Marines regularly deploy to Norway to conduct Cold Weather, Arctic and Mountain Warfare training. A total of 1200 personnel deployed to Norway in 2010 over a 14-week period. Patients, whose injuries prevented them from continuing training, were returned to the UK via AEROMED. The aim of this investigation was to describe the epidemiology of musculoskeletal injuries during cold weather training. All data on personnel returned to the UK was prospectively collected and basic epidemiology recorded. 53 patients (incidence 44/1,000 personnel) were returned to the UK via AEROMED. 20/53 (38%) of cases were musculoskeletal injuries (incidence 17/1000 personnel). 15/20 musculoskeletal injuries were sustained while conducting ski training (incidence 13/1,000): 4/20 were non-alcohol related injuries, 1/20 was related to alcohol consumption off duty. Injuries sustained whilst skiing: 5/15 sustained anterior shoulders dislocation, 5/15 Grade 1-3 MCL/LCL tears, 2/15 sustained ACJ injuries, 1/15 crush fracture T11/T12, 1/15 tibial plateau fracture and 1/15 significant ankle sprain. Non-Training injuries: 1 anterior shoulder dislocation, 1 distal radial fracture, 1 olecranon fracture, 1 Scaphoid Fracture and one 5th metatarsal fracture. 60% of injuries were upper limb injuries. The most common injury was anterior shoulder dislocation 6/20 (Incidence 5/1000). Our results suggest that cold weather warfare training has a high injury rate requiring evacuation: 4% of all people deployed will require AEROMED evacuation, and 2% have musculoskeletal injuries. Ski training causes the majority of injuries, possibly due to the rapid transition from non-skier to skiing with a bergen and weapon. Military Orthopaedic and rehabilitation units supporting the Royal Marines, should expect sudden increases in referrals when large scale cold weather warfare training is being conducted. Further research is required to see if musculoskeletal injury rates can be decreased in cold weather warfare training
