A Case Report of an Open Pan-Talar Dislocation

Abstract

Total talar extrusion is a rare injury that most commonly occurs secondary to high-energy trauma. There are few reported cases of open dislocations in literature and still, there is no consensus regarding the appropriate treatment of the extruded talus. In this case report, we present a 12-month follow-up of a patient with an open talar dislocation with extrusion treated with immediate surgical debridement, reduction and temporary fixation with one Steinmann pin. No infection was reported, although the patient developed avascular necrosis.

Total Talar Prosthesis, Learning from Experience, Two Reports of Total Talar Prosthesis after Talar Extrusion and Literature Review

“…high-energy trauma and has been described 91 times in the literature [6][7][8][9][10][11][12][13][14]. Due to their peculiar and limited blood supply, talar dislocations are difficult to treat: Re-implantation of the extruded talus is possible but frequently presents fearsome complications such as avascular necrosis, infections, and osteoarthritis [7,8,15].…”

“…It consists of the complete dislocation of the talus from the tibiotalar, talocalcaneal, and talonavicular joints [ 5 ], usually following a forced tibiotalar plantar flexion combined with excessive supination. It is determined by high-energy trauma and has been described 91 times in the literature [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. Due to their peculiar and limited blood supply, talar dislocations are difficult to treat: Re-implantation of the extruded talus is possible but frequently presents fearsome complications such as avascular necrosis, infections, and osteoarthritis [ 7 , 8 , 15 ].…”
