Rationale: A postoperative spinal epidural hematoma (PSEH) is among the most devastating complications following spine and spinal cord surgery, and it should be considered before performing microendoscopic decompression as part of minimally invasive surgery, since early recovery is one of the advantages of this procedure.

Patient Concerns: A 70-year-old woman with lumbar spinal stenosis at L4-5 underwent tubular surgery with the assistance of endoscopic laminectomy (MEL), but 2 days after the surgery, the patient noticed decreased lower limb sensation and power of the right leg, and she developed numbness from the level of L5 and weakness from the L4, 5 myotome distally.

Diagnoses: An epidural hematoma at the L4-5 surgical site was found on magnetic resonance imaging of the lumbar spine and evacuated operatively.

Tubular surgery with the assistance of endoscopic surgery via a paramedian or midline approach for lumbar spinal canal stenosis at the L4/5 level.

Background: Lumbar spinal canal stenosis surgery has recently improved with the use of minimally invasive techniques. Less invasive procedures have emerged, and microendoscopic decompression through smaller incisions is frequently performed. Tubular surgery with the assistance of endoscopic surgery procedures has led to particularly remarkable changes in surgery, with reduced tissue trauma and morbidity.

Postoperative neck symptoms of posterior approach for cervical compressive myelopathy: Expansive open-door laminoplasty vs. segmental partial laminectomy.

Background: Laminoplasty is widely accepted as a standard treatment of cervical compressive myelopathy. However, due to the risk of postoperative complications such as neck symptoms, segmental partial laminectomy (SPL) is performed instead, which results in fewer postoperative symptoms. The aim of this study was to describe the difference in the incidence and severity of postoperative neck symptoms between traditional C3-C7 expansive open-door laminoplasty (ELAP) and SPL.

Therapeutic efficacy of nonsteroidal anti-inflammatory drug therapy versus exercise therapy in patients with chronic nonspecific low back pain: a prospective study.

Therapy for chronic, nonspecific low back pain is mainly conservative: medication and/or exercise.　Pharmacotherapy, however, has side effects, and the quantities of concomitant drugs in older persons require attention.　Although exercise promises improved function, its use to alleviate pain is controversial.

The predictive factors for the resorption of a lumbar disc herniation on plain MRI.

Previous studies have noted the morphologic changes of lumbar disc herniation (LDH) in conservative treatment and predictive value of the resorption of LDH by using contrast-enhanced MRI. However, there are few reports that note the predictive value of plain, non-enhanced MRI. Therefore, no definite predictive factors for the resorption of LDH have been detected on plain MRI.
