Failure properties and strain distribution analysis of meniscal attachments.
The menisci are frequently injured due to both degeneration and traumatic tearing. It has been suggested that the success of a meniscal replacement is dependent on several factors, one of which is the secure fixation and firm attachment of the replacement to the tibial plateau. Therefore, the objectives of the current study were to (1) determine the failure properties of the meniscal horn attac...
متن کاملIndomethacin and celecoxib impair rotator cuff tendon-to-bone healing.
BACKGROUND Nonsteroidal anti-inflammatory drugs are commonly prescribed after rotator cuff repair. These agents can impair bone formation, but no studies have evaluated their impact on tendon-to-bone healing. HYPOTHESIS Traditional nonselective nonsteroidal anti-inflammatory drugs and cyclooxygenase-2-specific nonsteroidal anti-inflammatory drugs interfere with tendon-to-bone healing. STUDY...
متن کاملProximal Biceps Tendon and Rotator Cuff Tears.
The long head of biceps tendon (LHBT) is frequently involved in rotator cuff tears and can cause anterior shoulder pain. Tendon hypertrophy, hourglass contracture, delamination, tears, and tendon instability in the bicipital groove are common macroscopic pathologic findings affecting the LHBT in the presence of rotator cuff tears. Failure to address LHBT disorders in the setting of rotator cuff...
متن کاملSupraspinatus and Infraspinatus Rotator Cuff Repair Prevents Mechanical Damage to the Intact Subscapularis Tendon in a Rat Model
Introduction Rotator cuff tendon tears are a common cause of pain and disability. An intact rotator cuff stabilizes the glenohumeral joint, allowing for concentric rotation of the humeral head on the glenoid. However, large tears involving the supraspinatus and infraspinatus tendons may disrupt the normal balance of forces, resulting in abnormal joint loading which can cause secondary damage to...
متن کاملVascularity of the Rotator Cuff Tendon
Previous perfusion studies of the rotator cuff have demonstrated an area of bypovascularity in the distal part of the supraspinatus tendon. This has been implicated in the pathogenesis ofits rupture. We performed a quantitative histological analysis of the vascularity of the tendons ofsupraspinatus and infraspinatus. Vessel number, size and the percentage of the tendon occupied by vessels were ...
