BACKGROUND Structural characteristics of rotator cuff tears are used in surgical decision making. However, data on the association of tear size with patient-reported pain and function are sparse. PURPOSE To assess the association of tear size, fatty infiltration, and muscle atrophy with shoulder pain/function in patients with cuff tears undergoing operative and nonoperative treatment. STUDY...

The TFCC consists of triangular fibrocartilage (TFC), meniscus homologue, ulnolunate ligament, ulnotriquetral ligament, radioulnar ligament, and sheath floor of the extensor carpi ulnaris (ECU). The TFCC functions as a stabilizer of the ulnocarpal and DRU joints, load distributor between ulna and ulnar carpus and introduces smooth forearm rotation. The TFCC is a hammock-like shape supporting an...

Relevance. This paper reviews the latest evidence concerning distal biceps tendon repair, particularly aspects such as tear type, patient demographics, diagnostic clues, surgical indications, anatomy of insertion, radial tuberosity, single- vs double-incision reconstruction, fixation techniques (bone tunnels, button, interference screw, button plus screw) and postoperative outcomes. Material me...

Introduction The long head of the biceps (LHB) tendon has different loading patterns in its intraand extra-articular regions. The intra-articular region is exposed to complex loads including tension, compression, shear, and frictional forces, while the extra-articular portion is subjected primarily to tensional loads. Previous studies have also shown that the intra-articular region has a more d...

Tears on the bursal and articular sides of the rotator cuff tendons are known to behave differently and strain is thought to play a role in this difference. This study investigates the effect of tear location on the changes in three strain measurements (grip-to-grip, insertion, and mid-substance tissue) in a sheep infraspinatus tendon model during axial loading. We introduced a 14 mm wide defec...

Traumatic rotator cuff tears in patients younger than 25 years are rare events, with few reports in the literature. When compared with the more mature shoulder, the young, healthy supraspinatus tendon is a robust tendon that is able to absorb a significant amount of energy before tendon failure. Therefore, the diagnosis of a rotator cuff tear can be often overlooked in this population due to th...

BACKGROUND Achillodynia is common and includes Achilles tendinopathy, partial Achilles tears and Achilles tendon ruptures. However, we believe an additional pathology should be considered for Achillodynia differentials - the intratendinous tear (ITT). METHODS Examinations of 740 achillodynic patients in one specialist centre were reviewed. ITTs were defined as a clearly visualised echopoor ar...

The aim of the study was to investigate proton transverse relaxation times combined with local magnetic field non-uniformities (T2*) of human Achilles tendon in vivo as a prospective marker for diagnosis of early pathological changes. Achilles tendon consists mainly of highly oriented collagen fibres resulting in lower water mobility, and therefore fast relaxation processes of protons. Mapping ...

Abstract Background The etiology of degenerative supraspinatus tendon (SSP) tear is still subject to discussion. Objectives Our objective was correlate clinical, radiological, and intraoperative signs mechanical outlet impingement in patients with SSP tears. Materials methods This prospective study included 100 tears that required surgery. Preoperatively, clinical radiological parameters (criti...

Rupture of the Pectoralis muscle tendon is usually rare. And when it does happen, Sports or exercises are most often the culprit. An abducted, extended and externally rotated shoulder is weak and adding tension to it, as happens during a bench press or throwing a ball, is likely to tear off the Pectoral tendon. Sites recognized are: At Tendon attachment, Musculo-tendinous junction and Muscle be...
