Effects of isolated Weber B fibular fractures on the tibiotalar contact area

Complications in ankle fracture surgery

“…However, for many reasons, anatomic fracture reduction may not be achieved (Horisberber et al 2009, Luebbeke et al 2012. Failure to reproduce the anatomic relationship of the distal tibia and fibula leads to altered loading of the tibiotalar joint (Ramsay and Hamilton 1976, Thordarson et al 1997, Harris and Fallat 2004, Lloyd et al 2006) and subsequent post-traumatic arthritis (Lindsjö 1981, Pettrone et al 1983, Leeds et al 1984, Lindsjö 1985, Rukavina 1998) with poor functional outcomes (Joy et al 1974, Pettrone et al 1983, Mont et al 1992, Weening et al 2005, Wikerøy et al 2009, Sagi et al 2012. Surgical site infection (SSI) is one of the most common complications following ankle fracture surgery (Shephers et al 2011).…”

Intraoperative Diagnosis of Syndesmosis Injuries in External Rotation Ankle Fractures

“…Studies have shown as little as 1 mm of talar displacement can increase joint contact loads by as much as 42%. [6][7][8] Accurate diagnosis of syndesmotic instability remains a challenge. Previously plain radiography, biomechanical criteria, and more recently ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and ankle arthroscopy [9][10][11][12][13][14] have been used in an attempt to diagnose unstable syndesmoses and guide treatment.…”

Weight bearing cone beam CT scan versus gravity stress radiography for analysis of supination external rotation injuries of the ankle

“…Similar to weight-bearing radiography, weight-bearing CBCT can predict stability of these ankle fractures by showing restoration of the MCS, and might be used to indicate patients for non-operative treatment. A SER mechanism of injury to the ankle frequently results in a lateral malleolus fracture as well as injury to the medial When medial injury is significant, the ankle mortise may be unstable and the talus may shift laterally, resulting in significant changes in joint contact biomechanics (1,2,24,25). Unless the talus is anatomically restored to its position under the distal tibia and in the ankle mortise, it may represent a significant risk of the development of ankle arthritis and its associated symptoms.…”

“…Ankle fractures that occur from excessive supination and external rotation (SER) are among the most common seen in orthopedic departments, and demand precise treatment because of potential biomechanical and clinical implications on the articulating weight-bearing surfaces of the ankle joint (1,2). Undisplaced or minimally displaced lateral malleolus fractures without medial injury are likely to be stable, and can be treated non-operatively with functional bracing and early mobilization (3)(4)(5)(6)(7).…”
