Abstract
Background
Viewing the existing literature, one can find several documents about dislocation of the peroneal tendons. Clinical findings, diagnostics, and therapy are well described. Instead, the list of documents describing dislocations of the posterior tibial tendon is short. We found no case in which a dislocation of both long peroneal tendon and posterior tibial tendon is described.
Case presentation
We present a case of a 29-year-old male patient who sustained an ankle injury after a fall at a boulder gym. He admitted himself with severe pain, tenderness, and swelling of his left ankle. Dislocation of the posterior tibial tendon and simultaneous dislocation of the long peroneal tendon was diagnosed using x-ray, computed tomography, and magnetic resonance imaging. Transosseous suture repair with periosteal augmentation of the flexor retinaculum was performed at the medial malleolus. At the lateral malleolus, transosseous suture was used to repair the superior retinaculum. The ankle was immobilized following surgery. The patient underwent physical therapy afterwards. The treatment resulted in good recovery, and the patient returned to the same level of performance at rock climbing.
Conclusion
Our novel finding is that simultaneously sustained dislocations of the posterior tibial tendon and the long peroneal tendon may occur and can be successfully treated as if each injury is treated individually. Level of evidence Level V, case report.
