About this trial
The aim of this study is to evaluate the outcomes after non-operative treatment of weightbearing stable bi-and trimalleolar ankle fractures.
Eligibility criteria
Qualifiers
-With bi- and trimalleolar ankle fractures with less than 7 mm medial clear space on non-weightbearing radiographs that are deemed stable by weightbearing radiographs.
With type B medial malleolus fractures between the tip and the plafond and type C medial malleolus fractures at the level of the plafond (Herscovici classification). (6)
With fractures in the distal 1/3 of fibula (not-Maisonneuve)
Enabling stability evaluation within 14 days after injury
Disqualifiers
- With primary unstable ankle fractures, > 7mm medial clear space on primary radiographs
With fracture reduction prior to initial radiographic evaluation, open fracture, fractures resulting from high-energy trauma or multi trauma and pathological fracture
With type A medial malleolus avulsion fractures < 5mm (at the tip of the malleolus), that are not suitable for surgical intervention.
With Herscovici type D fractures, involving Lauge-Hansen SA2 fractures (supracollicular fracture - vertical, oblique or transverse direction of the plafond)
