Journal of Foot and Ankle Surgery 2000 May-June; 39(3):194-197. Radsource MRI Web Clinic:Lateral Hindfoot Impingement. The objective of this article is to review the pathophysiology and clinical presentation of impingement syndromes at the ankle joint (anterolateral, anterior, anteromedial, posteromedial, and posterior) and the role of MRI in evaluating impingement at the ankle joint and at extraarticular locations, lateral to the ankle joint (talocalcaneal and calcaneofibular). Medial collateral ligament Injury of the knee (MCL Tear) are the most common ligament injuries of the knee and are frequently associated with ACL tears. (OBQ15.89) Anterior talofibular ligament thickening and soft-tissue fullness in the lateral gutter may be suggestive of the diagnosis, but the reliability of the latter finding is questionable. Approximately 8-15 cm proximal to the ankle, the SPN pierces the lateral compartments deep fascia to become subcutaneous. Which of the following is the most appropriate term to describe the abnormal finding in the region marked with the two asterisks? 16, No. Rarely, operative management is indicated for patients with persistent symptoms who fail nonoperative management. A arthroscopic shave and burr were used to remove any scar soft tissue and tibial and talar osteophytes. Posterior-ankle impingement (PAI) syndrome describes a group of pathological entities that result from repetitive plantar flexion of the foot that causes repeated compression and entrapment of soft tissues, bony processes or unfused ossicles between the posterior-tibial plafond and the superior surface of the calcaneum. He notes pain when using a hammer. Peripheral nerve entrapment occurs at specific anatomic locations. 23, No. The frequency of lateral gutter fullness and anterior talofibular ligament thickening on MR images was higher in the 12 ankles with impingement (seven [58%] and seven [58%] ankles, respectively) than in the 20 control ankles (seven [35%] and five [25%] ankles, respectively), but these trends did not reach statistical significance.

PubMed comprises more than 34 million citations for biomedical literature from MEDLINE, life science journals, and online books. MRI is valuable in assessing both osseous and soft-tissue abnormalities associated with impingement syndromes. Assists with the diagnosis of the Achilles tendon rupture based on the presence of five radiological X-ray signs. 1, Orthopedic Clinics of North America, Vol. Pain in the posterior aspect of 8600 Rockville Pike Subacromial impingement is the most common cause of shoulder pain which occurs as a result of compression of the rotator cuff muscles by superior structures (AC joint, acromion, CA ligament) leading to inflammation and development of bursitis.

He promptly undergoes operative irrigation and debridement, reduction, vascular bypass of the brachial artery, and hinged elbow fixator placement for 6 weeks. CONCLUSION The purpose of this paper is to illustrate the normal anatomy of peripheral nerves in the upper and lower These help keep your ankle and foot steady when you walk. 31, No. However, a May not be sufficient to identify malleolar fractures. accessory bone is recommended.3.

Careers. weight-bearing immobilization, and physiotherapy. andrea.donovan@sunnybrook.ca PMID: 20729435 This injury is far less common than the lateral ankle sprain. lateral ankle pain due to subfibular impingement is a late symptom. Familiarity with the anatomy and the magnetic resonance imaging (MRI) features of nerve entrapment syndromes is important for accurate diagnosis and early treatment of entrapment neuropathies. There was a significant improvement in the range of dorsiflexion but not of plantar flexion, and one poor result was due to a superficial infection, and two other patients had residual numbness of the foot which persisted for several months.
