Sacroiliac joint (SIJ) can cause low back pain when its joint capsule and ligamentous tissue are damaged. We report our experience in treating three SIJ dysfunction patients presenting with acute low back pain (a 38 year-old male, a 24 year-old male, and a 32 year-old female). SIJ dysfunction was diagnosed using the one-finger test, the modified Newton test, and SIJ injection. ⋯ The two male patients returned to work and the problems have not recurred. Although our female patient resumed daily life as a housewife, her condition recurred at intervals of 2-3 months and she required regular SIJ injections. The prevalence of SIJ dysfunction of low back pain is about 10%, so it should be considered as a differential diagnosis when treating low back pain and designing treatment for lumbar spinal disorders.

We describe three cases of cerebrospinal fluid edema (CFE) which occurred in hydrocephalic adult patients who underwent ventriculo-peritoneal shunt operations. After shunt operations, the shunt systems were functioning well and symptoms due to hydrocephalus were resolved. ⋯ The one-way valve mechanism is thought to be a possible mechanism of CFE in these cases. Although CFE is a very rare complication to occur after shunt operations, it is necessary to follow up the patients even if the shunt is functioning well.

Chronic subdural hematoma is a rare complication of epidural anesthesia. This report describes the case of a 34-year-old woman who presented with postpartum headache after she received epidural anesthesia for labor pain. The anesthesiologist's record did not show any anesthesia-related complication. ⋯ Left burr hole trepanation was performed and this was followed by uneventful postoperative course. Right chronic subdural hematoma was managed by conservative treatment, and it completely recovered after 4 weeks. Chronic subdural hematoma should be considered when postpartum patients who have received epidural anesthesia present with mild to severe, persistent, and non-postural headache.

Lumbar canal stenosis (LCS) and lumbar foraminal stenosis (LFS) are frequently observed in elder patients. For patients with radiculopathy caused by both LCS and LFS, surgical manipulations require nerve root decompression from its exit zone to the lateral part of the vertebral foramen, and often need spinal instrumentation. In the present report, we performed a new strategy of surgical decompression without spinal fixation. ⋯ The patient was relieved from the radicular pain after the operation, and returned to her previous activity of daily living. One-year after the operation, she was free from the radiculopathy, and radiograms showed no fracture in the preserved left L4 lamina. Lateral fenestration combined with bilateral spinal canal decompression through contralateral laminotomy is potentially a surgical option for radiculopathy caused by both LSC and LFS.

Subclavian steal syndrome (SSS) is caused by hypoplasia of a vertebral artery or stenosis or occlusion of the subclavian artery or the brachiocephalic artery with subsequent retrograde filling of the subclavian artery via the contralateral vertebral artery. Symptoms of SSS are due to vertbrobasilar insufficiency or ischemia of the ipsilateral upper extremity, and they may include dizziness, syncope, ataxia, arm claudication, hand numbness or a decrease in brachial blood pressure on the affected side. However, most SSS cases are asymptomatic and they are classified as subclavian steal phenomenon (SSP). ⋯ SSS was asymptomatic although there was laterality in blood pressure in the patient's bilateral upper limbs. Thyroid tumor was regarded as benign by radiological findings, laboratory data, and physical examination. If SSS becomes symptomatic, removal of the thyroid tumor may be indicated.
