“…The locking plate construct had a significantly higher torque to failure than the antiglide plating construct (16.5 AE 7.61 Nm vs. 10.54 AE 6.42 Nm, p = 0.02). The energy spent on failure was about 170% higher for the lateral locking plate compared to the antiglide plate (426 AE 164 Nm/degree vs. 248 AE 102 Nm/degree, p = 0.048).…”

“…The tibia was secured into an aluminum cylinder using multiple rows of sharp tipped bolts [4,[10][11][12] screwed radially to hold the tibia securely. This aluminum cylinder was secured to an X-Y platform that allowed the aluminum cylinder and the tibia to slide in the anteroposterior and mediolateral directions.…”

“…In a cadaver study, Ho et al

compared syndesmotic fixation alone and syndesmotic fixation with the addition of a fibular plate to determine whether the addition of a fibular plate would lead to better biomechanical properties. The results showed higher rotational stability, load to failure and stiffness with the plate compared to the syndesmotic fixation-only technique.…”
Objectives: To evaluate syndesmosis-only fixation in Weber C ankle fractures with tibiofibular diastasis and to assess the need for additional fibular fixation. Methods: Twenty-one patients with Weber C ankle fractures and tibiofibular diastasis were followed for at least 24 months after treatment. In treatment of the Weber C fractures, only a syndesmosis screw was used through a mini open lateral incision if the syndesmosis could be anatomically reduced and fibular length and rotation could be restored. At follow-up, anteroposterior tibiofibular distance, lateral fibular distance, medial mortise distance and fracture healing were compared and patients were clinically evaluated using the Olerud and Molander ankle scale scoring system. Results: The average duration of follow-up was 49 months and the decreases in anteroposterior tibiofibular distance and lateral fibular distance were statistically significant. At the last follow-up the average clinical score was 86. Ankle mortise was reduced at follow-up in all cases except one, which resulted in a late diastasis. Conclusions: Syndesmosis-only fixation can be an effective method of treating Weber type-C lateral malleolar fractures with syndesmosis disruption in cases where intraoperative fibular length can be restored and anatomical syndesmosis reduction can be achieved. Level of Evidence IV, Case Series.
Background:With the length of the fibula restored and the syndesmosis reduced anatomically, internal fixation using a plating device may not be necessary for supra-syndesmotic fibular fractures combined with diastasis of inferior tibio-fibular joint. A retrospective observational study was performed in patients who had this injury pattern treated with syndesmosis-only fixation.Materials and Methods:12 patients who had Weber type-C injury pattern were treated with syndesmosis only fixation. The treatment plan was followed only if the fibular length could be restored and if the syndesmosis could be anatomically reduced. Through a percutaneous or mini-open reduction and clamp stabilization of the syndesmosis, all but one patient had a single tricortical screw fixation across the syndesmosis. Patients were kept non-weight-bearing for 6 weeks, followed by screw removal at an average of 8 weeks. Outcomes were assessed using an objective ankle scoring system (Olerud and Molander scale) and by radiographic assessment of the ankle mortise.Results:At a mean follow-up of 13 months, the functional outcome score was 75. Excellent to good outcomes were noted in 83% of the patients. Ankle mortise was reduced in all cases, and all but one fibular fracture united without loss of fixation. Six patients had more than one malleolar injury, needing either screw or anchor fixations. One patient had late diastasis after removal of the syndesmotic screw and underwent revision surgery with bone grafting of the fibula. This was probably due to early screw removal, before union of the fibular fracture had occurred.Conclusion:We recommend syndesmosis-only fixation as an effective treatment option for a combination of syndesmosis disruption and Weber type-C lateral malleolar fractures.
