There are subtle findings which indicate a fracture of the posterior malleolus. The fracture is classified according to Weber as a type B fracture.Īccording to Lauge Hansen the oblique fibular fracture indicates that this is a Supination Exorotation injury stage 2 or higher. Sometimes CT is needed to get a better impression of the size of the fracture fragment of the posterior malleolus.įracture of the lateral malleolus starting anteriorly at the level of the joint extending proximally posteriorly. The size of the posterior malleolar fragment is probably less than 25% of the articular AP-diameter and will need no separate repair. This is an unstable fracture with dislocation that needs surgical repair. Only now you notice the posterior malleolar fracture on the lateral view. Look for stage 3 (posterior syndesmotic rupture or avulsion of the posterior malleolus) and stage 4 (rupture of the deltoid ligament or medial malleolar avulsion). a Weber B fracture.Īccording to Lauge Hansen the oblique fibular fracture indicates Supination Exorotation injury stage 2 or higher. The fracture starts at the level of the ankle joint and extends proximally, i.e. The lateral malleolus is 'pushed off' from anterior to posterior. Avulsion fracture of the medial malleolar.

Myers and colleagues also noted deep infection and open fracture decreased union rate, while syndesmotic fixation increased union rate. Additionally, the researchers found no differences in infection, implant failure or return to surgery. One nonunion (2.1%) occurred in the EWB group and 6 nonunions (4.3%) occurred in the LWB group. 2021 doi:10.3928/01477447-20210104-04.Īccording to the study, outcomes measures included fracture union, implant failure, complications, ambulatory status, infection rate and return to surgery. Forty-seven patients received management with early weight-bearing (EWB) – defined as 3 weeks or less after surgery – and 138 patients received management with late weight-bearing (LWB), defined as more than 3 weeks after surgery. Myers, DO, and colleagues from OhioHealth Grant Medical Center in Columbus, Ohio, performed a retrospective review of data from 185 patients who underwent surgical stabilization for trimalleolar ankle fractures. Researchers saw no differences in union rate, infection, implant failure or return to the OR between patients operatively treated for trimalleolar ankle fractures who were assigned to early weight-bearing vs. If you continue to have this issue please contact to Healio
