MRI of popliteo-meniscal fasciculi of the knee: a pictorial review.

The popliteomeniscal fascicules (PMFs) provide the attachment of the lateral meniscus to the popliteus musculotendinous region, forming the floor and the roof the popliteal hiatus. In the second half of 1900's, some anatomic studies claim the important function of the PMF as stabilizers of the lateral meniscus; these anatomical structures work in conjunction with the popliteus musculotendinous unit to prevent excessive lateral meniscal movement and possible meniscus subluxation. A correct diagnosis of the PMFs pathology is crucial to establish the suitable surgical treatment for each patient.

Sonography of chondral print on humeral head.

Objective: The aim of this study is to determine the diagnostic accuracy of sonography in order to identify the chondral print on the humeral head.

Materials And Methods: In total, 44 patients who had already been candidates for arthroscopic surgery were prospectively studied with ultrasound to assess the presence of humeral subchondral erosion at the level of the biceps pulley; no patient had undergone previous surgery or radiographic calcification of rotator cuff tendons. Using arthroscopy as the reference standard the sensitivity, specificity, positive predictive, negative predictive and diagnostic accuracy values were calculated.
