[Treatment procedure in humeral shaft fractures with primary or secondary radial nerve damage].

We give an account of 28 patients with fractured humerus diaphysis, suffering from primary and seven patients suffering from secondary lesion of the radialis nerve, all treated by operation. In each case the radialis nerve was exposed and the fracture was treated by fixation with compression plates. In case of primary lesions of the radialis nerve, we found intraoperative damages by traction (six times), contusions (seven times), intraneural hämatomas (six times) and for one time perforation of the nerve by bones. The rest of this group (eight times) did not show any pathological finding. Those patients with secondary lesion of the radialis nerve showed damages by traction (three times) and in two cases the nerve was walled up by callus or connective tissue. Two times we could not find any pathological alteration of the nerve. 23 (six) out of 28 (seven) patients with primary (secondary) lesion of the radialis nerve could be followed up. On this occasion we stated complete neurological restitution 20 times (four times) and incomplete restitution three times (two times). The great number of pathological findings, which necessitate operative treatment, the short duration of remission and the high rate of restitution confirm us to leave the way of conservative treatment in cases of primary or secondary lesion of the radialis nerve and the indication of acute operation is given.
