Objective: To present the case of an intercollegiate swimmer with a stage IV lateral talar dome injury and associated bony fragments. Background: Lack of distinct diagnostic symptoms, low index of clinical suspicion, and the difficulty of visualizing the early stages of this injury on standard x-rays cause frequent misdiagnosis of talar dome lesions. Differential Diagnosis: Ganglion cyst, with inflammatory synovitis secondary to rupture of cyst; loose bodies from previous occult fracture; osteochondral fracture. Treatment: Initial treatment with nonsteroidal antiinflammatory drugs and a posterior splint for comfort, followed by arthroscopic excision of loose bodies with abrasion and drilling arthroplasty. Uniqueness: Patient presented to the team physician for care of acute left medial ankle pain after the athletic trainer had attempted to rupture a ganglion cyst on the anterolateral aspect of the patient's ankle. Conclusions: Increased clinical suspicion is necessary to correctly diagnose osteochondral lesions, particularty in the early stages. Aggressive treatment of talar dome lesions has a good success rate and may be an attractive option for competitive athletes. Verf.-Referat
