Tibialis posterior tendon dislocation: A case report

Traumatic Dislocation of the Posterior Tibial Tendon: A Case Report and Review of the Literature

“…7 On surgical exploration, the findings include a rupture or avulsion of the flexor retinaculum, a flat retro malleolar sulcus, elevation of the retinaculum, or a loose retinaculum. 1,8 Rolf et al reported a case of dislocation of the PTT that was diagnosed by CT and ultrasound. In this study, the retromalleolar groove architecture was not mentioned.…”

Dislocated Posterior Tibial Tendon Treated With Plate Buttress Fixation in a Collegiate Gymnast

“…17,18 There are very few documented cases in the English-language literature and none to our knowledge that use the assistance of plate fixation to achieve repair of the flexor retinaculum. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] The first case of a PTT dislocation was reported in 1874 by Martius, who suffered the injury after falling out of a balloon. 5 Most cases involve a traumatic injury-for example, athletic injury or motor vehicle accident; however, there are reports of nontraumatic dislocation, specifically occurring after operations for tarsal tunnel syndrome.…”

“…3,11,16 This injury often involves a failure of the flexor retinaculum or the retromalleolar groove to hold the tendon in its anatomical location. 1,2,16 We report a case of PTT dislocation in a collegiate gymnast during competition and offer our technique with a buttress plate in the setting of a partially torn, attenuated flexor retinaculum. Previous studies have discussed direct repair of the torn flexor retinaculum with suture anchors or suture alone, reconstruction with osteoperiosteal flaps or bone blocks, and retromalleolar groove deepening.…”

“…[21][22][23][24] Most case reports describe operative treatment for PTT dislocations, which typically involves repair of the flexor retinaculum with or without deepening of the retromalleolar groove. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Several case reports exist in the literature, with the largest series of 7 dislocations by Ouzounian and Myerson. 7 This series included 6 acute traumatic dislocations and 1 chronic dislocation secondary to multiple local steroid injections.…”

“…Dislocation of the posterior tibial tendon (PTT) is an uncommon injury with few case reports described in the literature. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Injury to the PTT can occur as a result of acute or repetitive trauma but can also occur without a history of injury. 15 Prompt diagnosis is challenging because patients often present in the acute stage with swelling that hides the dislocation and an inability to bear weight that can mimic other, morecommon pathological processes of the ankle.…”
