BACKGROUND Many shoulder diseases are related to glenohumeral joint synovitis and effusion. The purpose of the present study is to detect effusion within the biceps long head tendon sheath as the sign of glenohumeral joint synovitis using ultrasonography, and to evaluate the clinical meaning of effusion within the biceps long head tendon sheath. METHODS A consecutive series of 569 patients wh...
Monkeys can gradually change the amplitude of the biceps spinal stretch reflex (SSR) without change in initial muscle length or biceps background electromyographic activity (EMG) (17). We investigated the concurrent behavior of synergist (brachialis and brachioradialis) and antagonist (triceps) muscles. Synergist background EMG remained stable while marked change occurred in biceps SSR amplitud...
EMG activity was recorded in biceps and triceps while subjects voluntarily flexed their elbows during a visual matching task. With fast flexion, the initial EMG was characterized by a triphasic pattern with a burst of activity first in biceps, then in triceps with a silent period in biceps, and finally in biceps again; these components were analysed quantitatively. Smooth flexion was characteri...
The use of shoulder ultrasound as an imaging modality has recently gained widespread attention; however, the ability of ultrasound to diagnose long head of the biceps tendon pathology accurately still remains unclear. The biceps tendons in 71 patients were prospectively evaluated by comparison of standard ultrasonographic and arthroscopic examinations. Arthroscopic examination was used as the g...
The long head of the biceps tendon is frequently involved in shoulder pathologies, often in relation to inflammatory or degenerative damage to the rotator cuff. Biceps tenodesis in the bicipital groove and tenotomy are the main treatment options. Tenotomy of the long head of the biceps tendon is a simpler and quicker procedure than tenodesis, and it does not require the use of implants. However...
Arthroscopic release of the long head of the biceps tendon: functional outcome and clinical results.
BACKGROUND Treatment of chronic, refractory biceps tendinitis remains controversial. The authors sought to evaluate clinical and functional outcomes of arthroscopic release of the long head of the biceps tendon. HYPOTHESIS In specific cases of refractory biceps tendinitis, site-specific release of the long head of the biceps tendon may yield relief of pain and symptoms. STUDY DESIGN Case se...
Despite the activity of the musculature around the elbow and the high angular velocity and stresses, distal biceps tendon injury is rare in the overhead athlete. The biomechanics of the throwing motion and electromyographic studies of the elbow provide useful clues as to why the biceps stays relatively healthy. Anterior elbow complaints are not uncommon in this population and can easily be mist...
We retrospectively studied the possibility that direct trauma to the biceps muscle might be the cause of poor elbow flexion and supination in 18 consecutive children with birth lesions of the brachial plexus who had delayed or impaired biceps recovery despite neurophysiological evidence of reinnervation. All had good shoulder and hand function at three months of age. Eight recovered a strong bi...
BACKGROUND Subpectoral biceps tenodesis with an interference screw has been shown to be an effective procedure from both an anatomic and biomechanical perspective. There have been no clinical outcome data on this procedure to date. HYPOTHESIS Subpectoral biceps tenodesis is an effective procedure in eliminating biceps tendinosis symptoms. STUDY DESIGN Case series; Level of evidence, 4. ME...
We describe an arthroscopic keyhole technique for proximal biceps tenodesis. The technique is safe, easy to reproduce, cost-effective, and less time consuming. It does not need any special instrumentation and is suitable especially for use in the developing countries. It enables examination of the biceps sheath and distal biceps tendon for unidentified tears, synovitis, and fibrosis.
