This guideline aimed to advance current understandings regarding the diagnosis, prevention and therapeutic interventions for ankle sprains by updating the existing guideline and incorporate new research. A secondary objective was to provide an update related to the cost-effectiveness of diagnostic procedures, therapeutic interventions and prevention strategies. It was posited that subsequent interaction of clinicians with this guideline could help reduce health impairments and patient burden associated with this prevalent musculoskeletal injury. The previous guideline provided evidence that the severity of ligament damage can be assessed most reliably by delayed physical examination (4–5 days post trauma). After correct diagnosis, it can be stated that even though a short time of immobilisation may be helpful in relieving pain and swelling, the patient with an acute lateral ankle ligament rupture benefits most from use of tape or a brace in combination with an exercise programme.New in this update: Participation in certain sports is associated with a heightened risk of sustaining a lateral ankle sprain. Care should be taken with non-steroidal anti-inflammatory drugs (NSAIDs) usage after an ankle sprain. They may be used to reduce pain and swelling, but usage is not without complications and NSAIDs may suppress the natural healing process. Concerning treatment, supervised exercise-based programmes preferred over passive modalities as it stimulates the recovery of functional joint stability. Surgery should be reserved for cases that do not respond to thorough and comprehensive exercise-based treatment. For the prevention of recurrent lateral ankle sprains, ankle braces should be considered as an efficacious option.

Background: Despite improvement in outcome after ankle arthroplasty, fusion of the ankle joint is still considered the gold standard. A matter of concern is deterioration of clinical outcome as a result of loss of motion and advancing degeneration of adjacent joints. We performed a long-term study to address these topics. Methods: Between 1990 and 2005 a total of 121 ankle arthrodeses were performed at our institute. Thirty-five cases were excluded because of simultaneous subtalar arthrodesis. Ten had died and ten were lost to followup. Six had a bilateral ankle arthrodeses, leaving 60 patients (66 ankles) eligible for followup. There were 40 males and 26 females with a mean age at surgery of 47 years. In 60 ankles, fusion was obtained using a two-incision, three-screw technique. All patients were assessed using validated questionnaires and clinical rating systems: Short Form 36 (SF-36), American Orthopaedic Foot and Ankle Society (AOFAS) Ankle and Hindfoot scale, Foot and Ankle Ability Measure (FAAM) and a subjective satisfaction rating. Radiological progression of osteoarthritis of the adjacent joints was assessed. Results: Fusion was achieved in 91% after primary surgery. In six patients rearthrodesis was needed to obtain fusion. The mean SF-36 score was 63 (SD, 22) for the physical component scale and 81 (SD, 15) for the mental component scale. The mean FAAM score was 69 (SD, 17) and the mean AOFAS Ankle Hindfoot score was 67 (SD, 12). Ninety-one percent were satisfied with their clinical result. Infection occurred once. No other serious adverse events were encountered. In all contiguous joints significant progression of arthritis was appreciated. Conclusion: Ankle arthrodesis using a two-incision, three-screw technique was a reliable and safe technique for the treatment of end-stage osteoarthritis of the ankle. It resulted in a good functional outcome at a mean followup of 9 years. Progressive osteoarthritis of the contiguous joints was clearly appreciated but the functional and clinical importance of these findings remains unclear. Level of Evidence

Foot and ankle surgeons should take this into account when planning coronal deformity correction of the distal tibia. We believe whole lower leg images should be used to assess the medial distal tibial angle.
