Case Report
An oblique fracture of the distal third of the tibia, treated nonoperatively in a 14-year-old adolescent boy, did not unite because of ensnarement of the anterior tibial tendon (ATT) around an anterior inferior bony spike from the proximal tibial fragment. Computed tomography scan with 3-dimensional volume rendering aided in preoperative diagnosis. Surgical extraction of the tendon from within the fracture site and internal fixation led to successful union and full painless function./r/nBeware of possible ATT entrapment as a cause of irreducibility of oblique distal third tibial fractures with an anterior inferior bony spike of the proximal fragment.
