IntroductionPeroneal tendon injuries are a significant cause of lateral ankle symptoms in the active population. Accurate diagnosis and prompt treatment is important for minimizing the risk of long-term sequelae associated with chronic peroneal tendinopathy. Although several studies have been published on diagnostic strategies and treatment outcomes, there is no consensus on the optimal management of peroneal tendon pathologies.PurposeThe purpose of this ESSKA-AFAS consensus statement was to conduct an international and multidisciplinary agreed guideline on management of patients with peroneal tendon pathologies.MethodsUsing the Nominal Group Technique, a panel comprised of sixteen specialists spanning nine countries was convened by the ESSKA-AFAS board. In preparation for the meeting, relevant questions were identified and supported by a systematic literature search. During the meeting, the panel members gave presentations on each question, and the evidence supporting each subject was then vetted by open discussion. Statements were thereafter adjusted on the basis of the discussion and voted upon to determine consensus using a 0–10 range Likert scale. Agreement was confirmed when a mean score of at least 7.5 was reached.ConclusionThis ESSKA-AFAS consensus statement on the optimal management of peroneal tendon pathologies is the result of international and multidisciplinary agreement combined with a systematic review of the literature.Level of evidenceV.

Analysis of the salt and nutrient status of potting composts and growing substrates with the aid of the 1:25 weight extract -previously used in the Netherlands -has several disadvantages. The interpretation of analytical data based on the organic matter content is not very accurate because this content does not provide a true estimation of the moisture capacity. In addition the conductivity of growing media rich in gypsum gives an unfavourable impression of the salt status.Very good results were obtained in an investigation at the research station at Naaldwijk with a 1:1½ volume extract. For the preparation of this extract potting composts and growing substrates were standardised as regards moisture content, after which one part by volume was measured and
