چکیده

Introduction Rotator cuff tears are common conditions that often require surgical repair to improve function and relieve pain. Unfortunately, despite pain relief, the success associated with repair integrity is mixed, with 5-95% of patients having recurrent tears, resulting in decreased strength and function. Several factors may contribute to repair failure including age, tear size, and time from injury. However, the mechanical mechanisms resulting in repair failure are not well-established making clinical management difficult. Specifically, altered scapular motion (termed scapular dyskinesis) may be one important and modifiable factor which can place the healing tendon at risk for re-injury. Therefore, the objective of this study was to determine the effect of scapular dyskinesis on supraspinatus tendon healing following repair. We hypothesized that scapular dyskinesis will result in H1) diminished joint function and passive joint mechanics and H2) decreased supraspinatus tendon healing following repair due to the compromised mechanical environment present.

Objective Alteration of scapular position and motion is called scapular dyskinesis. Scapular dyskinesis is a common clinical problem. Strength of shoulder girdle muscles is important in shoulder motions and stability, so their weakness may lead to scapular dyskinesis. The aim of this study was to compare the maximum voluntary isometric force of shoulder girdle movements in subjects with and wit...

Scapular dyskinesis is detrimental to shoulder tendon properties and joint mechanics in a rat model.

Shoulder tendon injuries are frequently seen in the presence of abnormal scapular motion, termed scapular dyskinesis. The cause and effect relationship between scapular dyskinesis and shoulder injury has not been directly defined. We developed and used an animal model to examine the initiation and progression of pathological changes in the rotator cuff and biceps tendon. Sixty male Sprague-Dawl...

Common conditions in the overhead athlete.

The overhead athlete is at unique risk for injury because of the mechanics associated with rapid shoulder elevation, abduction, and external rotation. Angulation of the humeral head against the posterosuperior glenoid can cause rotator cuff tendon and labral impingement. The throwing or striking motion of baseball, softball, water polo, tennis, racquetball, and volleyball may result in scapular...

Healing of rotator cuff tendons using botulinum toxin A and immobilization in a rat model

BACKGROUND We evaluated effects of botulinum toxin A (Botox) and cast immobilization on tendon healing in a rat model. Injection of Botox into rat supraspinatus was hypothesized to reduce muscle active force and improved healing. METHODS Eighty-four supraspinatus tendons were surgically transected and repaired in 42 Sprague-Dawley rats (transosseous technique). After repair, supraspinatus mus...
