The elbow patients herein discussed feature common soft tissue conditions such as tennis elbow, golfers' elbow and olecranon bursitis. Relevant anatomical structures for these conditions can easily be identified and demonstrated by cross examination by instructors and participants. Patients usually present rotator cuff tendinopathy, frozen shoulder, axillary neuropathy and suprascapular neuropa...

Suprascapular nerve blockade improves pain, range of motion, and disability in acute and chronic shoulder pain. Pain relief usually lasts several hours with local anesthetic. If steroids are added, the relief lasts several weeks. Since repetitive steroid exposure is associated with several hazards, alternative long-term therapies would be desirable. Pulsed mode radiofrequency is a non-destructi...

Suprascapular nerve palsy has been frequently reported in athletes, particularly baseball pitchers, volleyball players, and weight lifters, but it is easily overlooked during the evaluation of shoulder pain. Entrapment of the suprascapular nerve is usually suspected only after atrophy is noted. The presence of painless weakness of the external rotator muscles should alert the clinician to the p...

VOL. 74-B, No. 3, MAY 1992 Most shoulders are arthrodesed in 20#{176} to 50#{176} of abduction, so that the suprascapular nerve is stretched when the arm is hanging by the side and may be more vulnerable to acute or chronic trauma. The arthrodesed shoulder is not always pain free even if there is radiographic evidence of bone fusion ; Cofield and Briggs (1979) reported moderate or severe pain i...

in this paper, the mean value of strain energy density criterion has been used to predict the critical fracture load in specimens with u-shaped notch under bending loads. an equation for calculation of averaged strain energy density in this zone has been presented. bending loads under mode i have been considered. two cases have been studied: 1) the control volume only includes the semicircular ...

In this paper, the influence of notch depth-to-width ratios on J-integral and critical load of Aluminium 8011 alloy specimens with U-notch under Mode I loading are studied. Using experiments, for a set of specimens having different notch depth–to–width ratios, J-integral was found and the same was verified using analytical methods. Further, using the results obtained from the experiments, failu...
