Purpose of reviewWith the increasing number of people running for exercise in our society, leg pain associated with running has increased in prevalence. Some of these sources of leg pain are anatomic structural abnormalities and some are caused by failure of anatomic structures. In this review, we will cover common causes of leg pain along with current thought on etiology, diagnostic tests and treatment algorithms.
Recent findingsThe use of newer imaging such as magnetic resonance arteriograms and better resolution on MRI scans can aid in gaining information to make an accurate diagnosis. Recent studies have suggested that the etiology of medial tibial stress syndrome is not caused by inflammation of the periosteum. Specimens of periosteum taken from patients with the condition show no evidence of inflammatory cells. The diagnosis of exertional compartment syndrome can be difficult to diagnose. With the advent of better resolution via MRI, changes within the affected compartment on T2-weighted images can aid in the diagnosis. Summary A thorough history along with newer diagnostic tests can aid in early diagnosis and treatment intervention. By gathering all of the information together and listening to the patients, we can treat them better and allow them to enjoy their physical activity longer.Keywords chronic exertional compartment syndrome, medial tibial stress syndrome, peroneal nerve entrapment, popliteal artery entrapment syndrome, saphenous nerve entrapment and leg pain, stress fractures
