수핵 탈출증에 대한 Cyriax 요추 견인법 = Cyriax's Lumbar Traction for Reduction of Nuclear Protrusion

다국어 초록 (Multilingual Abstract)

Traction is the treatment of choice for a small nuclear protrusin. The nucleus is soft and can be influenced by suction. Traction provides a method of improving on recumben-cy-the only effective treatment before traction was devised.
The intention is to achieve rapid reduction by distraction the joint surfaces mechanically-a positive purpose-instead of merely avoiding the compression of the upright posture by putting the patient to bed and leaving him there. Recumbency, usually successful in the end, wastes an endless amount of the patient's time and money. Traction carries the further advantage of enabling th epatient to be up and about, attending to his bussiness, during treatment. Traction brings the joint surfaces much farther apart than just lying in bed, a greater centripet force acts on the protruded part of the nucleus.
Traction has three beneficial effects;
1. Suction : a sub-atmospheric pressure induces a centripetal effect on the contents.
2. Distraciton : increase the distance between the articular edges. X-rays have shown an increase in width of the joint of 2.5 mm.
3. Ligamentous tightening : the posterior longitudinal ligament tightens which then exerts centipetal forde on a central protrusion.
