The risk factors of patients with and without radiculopathy after laminoplasty of the cervical spine were compared retrospectively. ⋯ Any one of patients' characteristics could not be correlated with postoperative cervical radiculopathy in this study. To prevent postoperative radiculopathy, it may be important during surgery to place the bony gutter on the medial side of the zygapophyseal joint and to keep the slope of the opened lamina within 60 degrees.

This case report illustrates the need to be aware of extraspinal causes of sciatica. A patient with a strangulated sciatic hernia showed the clinical features of sciatic leg pain, intestinal obstruction, and a left gluteal abscess. ⋯ The possibility of local pathology causing sciatic nerve compression should be considered when a patient reports sciatic leg pain, particularly if the presentation is atypical. Intestinal obstruction or the presence of a gluteal mass should suggest the possibility of a sciatic hernia.
