High-resolution ultrasound evaluation of the trapeziometacarpal joint with emphasis on the anterior oblique ligament (beak ligament)

Pedro A. Gondim Teixeira, Patrick Omoumi, Debra J. Trudell, Samuel R. Ward, more

Skeletal Radiology > 2011 > 40 > 7 > 897-904

Introduction The anterior oblique ligament is one of the main stabilizers of the trapeziometacarpal joint. Insufficiency of this ligament is closely linked to degenerative joint disease. High-resolution musculoskeletal ultrasound has advantages over magnetic resonance imaging (availability, dynamic nature, cost, patient comfort). This study evaluates the feasibility of ultrasound of the anterior oblique...

European Radiology > 2011 > 21 > 7 > 1492-1498

Objective The Lateral Collateral Ligamentous complex (LCL) is an important stabiliser of the elbow. It has a Y-shaped structure with three components. In this study, we sought to describe the ultrasound aspect of the individual components of this ligamentous complex and to evaluate the performance of ultrasound in both cadavers and in normal subjects. Methods Ten cadaveric elbow specimens underwent...

Skeletal Radiology > 2010 > 39 > 9 > 905-913

Objective To describe osseous landmarks that allow identification of the attachments of the ligaments and tendons in the distal medial aspect of the humerus. Materials and methods Reliable osseous landmarks in the distal medial aspect of the humerus were identified in 34 well-preserved specimens from a paleopathologic collection. These osseous landmarks were then sought in magnetic resonance (MR)...

Proximal tibial osteophytes and their relationship with the height of the tibial spines of the intercondylar eminence: paleopathological study

Mohammad Reza Hayeri, Masoud Shiehmorteza, Debra J. Trudell, Tori Hefflin, more

Skeletal Radiology > 2010 > 39 > 9 > 877-881

Objective Tibial spiking (i.e., spurring of tibial spines), eburnation, and osteophytes are considered features of osteoarthritis. This investigation employed direct inspection of the medial and lateral tibial plateaus in paleopathological specimens to analyze the frequency and morphological features of osteoarthritis and to define any relationship between the size of osteophytes and that of the intercondylar...

Chiasma crurale: intersection of the tibialis posterior and flexor digitorum longus tendons above the ankle. Magnetic resonance imaging–anatomic correlation in cadavers

Florian M. Buck, Ramon Gheno, Marcelo A. C. Nico, Parviz Haghighi, more

Skeletal Radiology > 2010 > 39 > 6 > 565-573

Purpose To determine the precise anatomy and magnetic resonance (MR) imaging appearance of the chiasma crurale in cadavers, paying special attention to degenerative changes Material and methods Twelve fresh human ankles were harvested from 11 nonembalmed cadavers (mean age at death 77 years) and used according to institutional guidelines. MR imaging and MR tenography were used to investigate the...
