“…1,4 Screw fixation alone, which is suitable for low-risk patients with minimal deformity and adequate bone stock, was reported with favorable clinical union rates ranging from 93% to 100%. 6,13 However, Dohm et al reported an unacceptable nonunion rate of 40% with this fusion technique. 5 Moreover, biomechanical evidence reported by Thordarson et al 22,23 suggested that screw fixation is not reliable in patients with osteopenic bone, which is common in posttraumatic arthritis and failed arthrodesis.…”

“…7,12 A popular internal fixation method of ankle fusion is partially threaded cancellous screws. 6,13 However, patients with a posttraumatic bone defect and/or poor bone quality after a long period of immobilization can require more rigid fixation. Dorsiflexion is the major stressor imparted to the fused ankle during normal gait, 18 therefore it can be rationalized that an anterior plate can provide more rigid fixation at the fusion gap.…”
The application of an anatomically contoured plate provides many advantages, including less soft tissue disruption by using a single anterior incision, ease of deformity correction, early rehabilitation, and high rate of union.

“…Fixation is obtained by three solid 16-mm partially threaded 6.5-mm screws: medial, lateral and posterior. 3 The talus is appropriately positioned under the tibial plafond. 4 The articular surface of the tibial plafond is divided into 4 quadrants ( Figure 1).…”

“…Ankle arthrodesis with internal screw fixation is biomechanically sound with proven results 3,6 and fewer complications than other techniques. 5 Solid screw use has been criticized as technically challenging, dissuading many surgeons despite considerable cost savings.…”
“…4 Since the first description of ankle arthrodesis in 1879, more than 30 techniques have been reported to achieve rates of successful fusion ranging from 80% to 100%. 1,5,7,8,10,11,15 One such technique is the use of interposition bone graft to correct coronal and sagittal malalignment. Use of allograft bone in foot and ankle surgery is an accepted practice in many reconstructive scenarios.…”
The tibiotalar joint fusion rate in this series compares favorably to historically published data for standard ankle fusion. Interposition allograft was an effective method for deformity correction in difficult ankle arthrodeses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
