[Surgical Procedure and Indication of Microendoscopic Discectomy].

Standard microscopic posterior decompression(MD) for lumbar disc herniation has been well established and is a familiar procedure to virtually all spinal neurosurgeons. Traditional surgical treatments are often associated with severe postoperative pain, disability, and dysfunction. This study aimed to describe the microendoscopic discectomy(MED) technique for lumbar disc herniation and report its surgical indications.

Dural Laceration Resulting in the Formation of Syringomyelia Caused by a Loosened Hydroxyapatite Intraspinous Spacer after Spinous Process-splitting Laminoplasty.

A 63-year-old man was admitted in our hospital with the chief complaint of upper limb numbness 3 years after undergoing spinous process-splitting laminoplasty (C3-C7) in another hospital. The hydroxyapatite spacers used for the laminoplasty had dislocated, resulting sensory disorders of the upper extremities. Additionally, loosened hydroxyapatite intraspinous spacers and syringomyelia were confirmed.
