Post-traumatic iliopsoas calcifications are extremely rare affections. We report the case of a patient who presented a right hip discomfort after a wakeboard accident. A thick calcification of the right iliopsoas was visible on standard X-rays. Surgery was performed by the removal of the calcification associated to a non-steroidal anti-inflammatory treatment. The result after six months was excellent. The patient has resumed his sports activities at the same level without discomfort and no recurrence of the ossification.
