What diseases can radial canal syndrome cause?

summary

As early as 1883, it was thought that the compression of radial nerve or its branches might be one of the causes of tennis elbow. For many years, tennis elbow has been the main diagnosis of pain in the proximal lateral forearm. In 1956, Michele and Krueger described the clinical symptoms and signs of radial pronator syndrome. In 1960, they further reported the clinical efficacy of proximal supinator release in the treatment of refractory tennis elbow. What diseases can radial canal syndrome cause?

What diseases can radial canal syndrome cause?

Radial tunnel syndrome is common in the dominant hand. Manual workers and athletes who need to repeatedly rotate the forearm are prone to this disease. Most of the patients were 40-60 years old, and the ratio of male to female was similar. There was no obvious history of trauma before onset, and the symptoms appeared gradually.

The main clinical manifestation of radial tunnel syndrome is pain. The pain is blunt, lateral elbow pain, can radiate to the proximal along the radial nerve, can also radiate to the distal along the posterior interosseous nerve. Upper limb movement can aggravate the symptoms. Nocturnal pain is more obvious, severe patients often wake up at night. Venous stasis, especially tourniquet, can also aggravate the pain.

Radial nerve entrapment at elbow can cause two kinds of entrapment syndrome: radial canal syndrome and posterior interosseous nerve entrapment syndrome. The etiology of the two diseases is similar, the location of entrapment is similar, and there is no significant difference in pathology. In clinical practice, only clinical manifestations are used to distinguish them. That is to say, radial canal syndrome is mainly characterized by sensory disturbance, and motor disturbance is not obvious. However, posterior interosseous nerve entrapment syndrome is mainly characterized by dyskinesia.

matters needing attention

Early conservative treatment can be used. Methods of conservative treatment include: fix the forearm in wrist extension, elbow flexion and forearm supination position to minimize the tension of radial canal and reduce the nerve entrapment. Local block, once a week, continuous 2-3 times as a course of treatment; At the same time, B vitamins and methimazole were taken orally. If conservative treatment is ineffective, surgical treatment is feasible.
