肘部管症候群 32 例の臨床的検討 : 特にその手術方法について

抄録

Ulnar nerve compression at the elbow is sometimes encountered in neurosurgical clinical practice. Early surgery is very important, since the effect of surgery depends on the duration of the symptoms and the presence of muscle atrophy. Operative management includes three major categories : simple decompression, medial epicondylectomy and anterior transposition. However, it is controversial which option is the most effective. We report our experience in 32 cases of subcutaneous anterior transposition of the ulnar nerve. Recurrence can be prevented by suturing the band together beneath the nerve and covering the nerve entirely in the subcutaneous fatty tissue. When ulnar nerve and spinal cord lesions coexist, diagnosis from neurologic and radiologic findings can be difficult. Therefore, electorophysiologic studies have become important in such cases.
