Os trigonum syndrome is one of the rare causes of posterior foot pain. Os trigonum, which is placed at the posterior of talus, is an accessory bone. Os trigonum syndrome causes back foot pain due to compression between talus and calcaneus. In this study, we present a case of os trigonum syndrome , which is a rare disease and is generally missed. A 65-year-old female patient with a complaint of left foot pain for the last 2 months persented to our outpatient clinic. In the physical examination, plantar flexion of the ankle and toe was painful. Patient’s pain was evaluated by the visual analog scale and noted as 8 cm. There was sensitivity at the posterior of talus during palpation. Os trigonum syndrome was diagnosed based on radiological examinations and a physical therapy program consisting of transcutaneous electrical nerve stimulation (TENS), cold pack, foot and ankle range of motion and strengthening exercises was started. After the treatment, pain VAS decreased to 2cm, and then the patient was followed clinically. As in our case, os trigonum syndrome should also be taken into consideration in patients complaining with posterior foot pain apart from other frequently encountered causes. In such cases, physical therapy programs are very effective in pain management and in reducing the cost of treatment.
