“…A case of the same technique was described in our previous study. [4] We have operated on 1 patient with a small incision and overall satisfying clinical results. But we did not describe any measurement and parameter of posterior talar process, also did not comment on the accuracy position of screw placement.…”

“…[12–15] Most reports focused on surgical technique for talar neck fracture. Although several studies have reported using different approach for medial or lateral tubercle fracture of posterior talar process, [4,9] none of the available literature described precisely the exact 3D position of screw placement with regarding to safe screw angles and lengths.…”

Background:Percutaneous screw fixation can provide stable fixation with a minimally invasive surgical technique for posterior talar process fracture.Objectives:The purpose of this study was to investigate the optimal posterior screw placement and the geometry of safe zone for screw insertion in the posterior talar process by analyzing with 3-dimensional (3D) technology.Methods:100 adult feet computed tomography (CT) scans were evaluated. CT data were imported into Materiaise's interactive medical image control system (MIMICS) 18.01 software for 3-dimensional reconstruction. Two 3.0mm-diameter screws were simulated from the posterior to anterior position for posterior talar process. The morphology parameters of posterior talar process were also quantitatively measured. The safe zone and the length and entry point of screw were defined.Results:The optimal entry point of screw for posterior talar process fracture was lateral tubercle from the posterior to anterior position. The safe zone of medial tubercle entry point was smaller in lateral tubercle. These gender-specific measurements were all significant (P <.001).Conclusions:The predefined zone with computer-assisted 3D techniques for the most frequently positioned percutaneous screws may aid in preoperative planning, shorten the operation time and reduce the incidence of surgical complications.

“…Most reports of talar posterior process fractures are associated with subtalar dislocation [7][8][9] and the recommended treatment is early open reduction and internal fixation (ORIF) or percutaneous screw fixation 8 . Subtalar dislocation accounts for 1-2% of all dislocations which makes treatment methods of talar posterior process fracture extremely rare 10 .…”

“…ORIF is a complicated technique due to the complex anatomical structure close to the ankle joint, subtalar joint, neurovascular bundle and flexor hallucis longus tendon. Previously, we described a case and defined a safe zone for percutaneous screw fixation 8,15 . Previous reports have described that ORIF treatment leads to a different outcome 9,16 .…”

The purpose of this study was to provide an initial assessment of treatment for talar posterior process fractures using open reduction and internal fixation (ORIF) through posteromedial approach and percutaneous screw fixation. From January 2014 to December 2018, 12 cases with displaced fracture of talar posterior process were treated in our department. The clinical and radiological results were assessed after 4 and 12 months of operation with Visual Analog Scale (VAS) pain and American Orthopedic Foot and Ankle Society (AOFAS) scores. ORIF was performed in four of the cases and percutaneous screw fixation was performed in eight of the cases. The average follow-up period was 13 months. Complications such as wound infection, nerve injury, screw loosening, malunion or nonunion of fracture were absent. For clinical assessment, considerable mprovements were observed for the AOFAS and VAS scores at 4 and 12 months postoperatively for both techniques. There was no significant difference for AOFAS scores and VAS scores between the two techniques (p > 0.05). Both techniques showed good functional outcome and were performed for posterior talar process fracture following the fracture displacement guidelines. Percutaneous screw fixation treatment with computer-assisted three-dimensional evaluation shortened the operation time and reduced incidences of surgical complications.
