Abstract
BackgroundStress fracture of the lateral tubercle of the posterior talar process in runners is extremely rare. Here, we describe a case of a female long-distance runner who sustained a stress fracture of the lateral tubercle of the posterior talar process. Osteosynthesis with screw fixation via two-portal hindfoot endoscopy achieved a good surgical outcome with a less invasive procedure.Case presentationAn 18-year-old female long-distance runner who belonged to her university’s road running club presented to our institution with a half-year history of persistent left hindfoot pain when running. Radiographs revealed a stress fracture of the lateral tubercle of the posterior talar process. Because the fracture showed no signs of healing 3 months after starting conservative therapy, osteosynthesis with screw fixation was performed via two-portal hindfoot endoscopy. Non-contrast computed tomography at 10 weeks postoperatively revealed consolidation of the stress fracture. At 15 weeks postoperatively, the patient was permitted to jog and return to athletic activity while wearing an orthosis. As of this writing 2 years postoperatively, she remains an active competitive runner.ConclusionsOsteosynthesis with screw fixation via two-portal hindfoot endoscopy was a less invasive procedure that successfully treated stress fracture of the lateral tubercle of the posterior talar process in this female long-distance runner.

Stress fracture of the lateral tubercle of the posterior talar process in runners is extremely rare
We describe a case of a female long-distance runner who sustained a stress fracture of the lateral tubercle of the posterior talar process, leading to Posterior ankle impingement syndrome (PAIS)
There has been no previous report of stress fracture of the lateral tubercle of the posterior talar process causing PAIS
Summary
Stress fractures affect approximately 1 to 7% of athletes. Runners have an especially high risk for this skeletal disorder, with the prevalence reaching as high as 20% [1, 2]. We describe a case of a female long-distance runner who sustained a stress fracture of the lateral tubercle of the posterior talar process, leading to PAIS. Because this disorder did not respond to conservative therapy, Kubo et al BMC Musculoskeletal Disorders (2019) 20:401 surgical therapy was applied. These landmarks were exposed under endoscopy, and a guidewire was inserted through a sleeve approximately 5 mm lateral to the FHL tendon at a level just above the subtalar joint (Fig. 3) through the posteromedial portal This seemed to be an adequate position to penetrate the fracture line.
