Diagnosis and treatment of radial head dislocation: The axis of the proxi- mal end of the radius must be centered over the middle of the capitulum humeri in all radiologically viewed planes (b). If this is not the case in one of the two x-ray planes (a), a radial head dislocation is present and a b must be reduced without delay ▬ lack of a trauma history, ▬ an excessively long radius, ▬ convex instead of concave shape of the proximal radial joint surface, ▬ bilateral occurrence, ▬ lack of deformation of the ulnar shaft. It should be noted that patients are often unable to recall any trauma and a dislocation is missed. In such cases the radius can continue to grow unhindered, the radial head changes its shape as a result of the missing joint partner and the ulnar shaft deformity can also remodel during the course of subsequent growth. Fracture types The classical Monteggia lesion involves the combination of a dislocated radial head and an ulnar shaft fracture. The directions of the ulnar shaft deformation and the radial a b c head dislocation correlate.

As such generic premarin 0.625 mg overnight delivery, therapists today are more likely to involve family members in treat- ment (Keefe et al buy cheap premarin 0.625mg on line. RESPONDENT THERAPY Background and Description Diverse pain management strategies deriving from the respondent formula- tion of pain are commonly used to treat chronic pain purchase premarin 0.625 mg free shipping, such as progressive muscle relaxation and biofeedback. The rationale identifies the pain–ten- 276 HADJISTAVROPOULOS AND WILLIAMS sion cycle as contributing to the pain experience, and thus reduction of muscle tension is the characteristic goal of treatment (Linton, 1982). Central to this view is that pain elicits a response of increased muscle tension, which itself produces more pain, and contributes directly to secondary problems such as sleep disturbance, immobilization, and depression (Lin- ton, 1982). Therapy includes educating patients regarding the association between tension and pain, and learning to replace muscle tension with an incompatible response, namely, relaxation (Turk & Flor, 1984). Relaxation therapy involves teaching patients to achieve a physiological sense of relaxation. Beyond physically reducing muscle tension, and thus pain, relaxation can have other aims, including anxiety reduction, assisting with sleep disturbance and fatigue, increasing well-being, and perhaps most importantly improving a sense of control. Progressive muscle relaxation is undoubtedly the most common form of relaxation training, and involves systematically tensing and the relaxing major muscle groups throughout the body (Turner & Chapman, 1982b). Biofeedback also involves relaxation of muscles, but is achieved through monitoring bodily responses, typically through a computer or apparatus, and providing patients visual or auditory feedback about their physiologi- cal responding. With intense scrutiny and examination, it is hoped that the patient will be able to learn how to control certain physiological responses related to pain (Arena & Blanchard, 1996). Many forms of biofeedback exist, but electromyographic (EMG) feedback, aimed to reduce muscle tension, is by far the most common with chronic pain patients. The focus has also largely been on headaches, although other conditions such as low back pain (Arena & Blanchard, 1996; van Tulder et al. At times, relaxation and biofeedback strategies are used on their own, but most commonly they are used in combination with each other as well as with the other treatment approaches described in this chapter. The ex- ception to this is with headache sufferers where biofeedback and relaxation are not infrequently used as sole treatment strategies (Arena & Blanchard, 1996). Treatment is most often offered on an outpatient basis in a group or individual format (Blanchard, 1992). These techniques help the patient to recognize and alter pain behavior patterns. As such responsibility for treat- ment rests largely with the patient (Keefe & Bradley, 1984). Home practice is often encouraged with these techniques, as is application to stressful sit- uations and events. One interesting finding that has emerged with respect to headache is that home practice appears to be important with relaxation, but not necessarily with biofeedback (Blanchard, 1992). In addition to relaxation strategies and biofeedback, imagery and hypno- sis are also used to achieve similar effects with chronic pain patients 10. PSYCHOLOGICAL INTERVENTIONS AND CHRONIC PAIN 277 (Arena & Blanchard, 1996). To the extent that they rely on effective relax- ation, respondent theory is relevant to them. Imagery involves the purpose- ful use of visual images to strengthen distraction and/or to transform as- pects of the pain experience. Hypnosis involves suggestion for decreasing discomfort or transforming or altering pain into less noxious sensations (Syrjala & Abrams, 1996). Evidence A number of reviews of the effects of relaxation therapy and biofeedback have been carried out with headache (e. There is evidence in support of both biofeedback and relaxation therapy. The research, however, is ham- pered by a number of problems, including differences among studies re- lated to procedures, patient groups, and duration of treatment (Turk & Flor, 1984).
