The year 2012 was the 50th anniversary of the Korean Neurosurgical Society, and in 2013, the 15th World Congress of Neurosurgery took place in Seoul, Korea. Thus, it is an appropriate occasion to introduce the world to the history of the Korean Neurosurgical Society and the foundation, development, and growth of Korean neurosurgery. ⋯ During the last 50 years, the Korean Neurosurgical Society and Korean neurosurgery have developed and grown enormously not only in quantity but also in quality. In every aspect, the turning point from the old to the new era of the Korean Neurosurgical Society and Korean neurosurgery was the year 1980.

Custom-made porous hydroxyapatite (HA) implant (Fin-Ceramica Faenza S.p.A., Italy) is a biomimetic, osteoconductive material. Margin fusion at the bone-implant edge, cell proliferation within implant pores, and osteointegration in an animal model have already been described. ⋯ Custom-made porous HA implant is an osteoconductive material able to promote osteogenesis, osteointegrate with bone tissue, provide an effective cranial reconstruction, and restore functional features of the skull. However, complete bone healing is still a complex and long process.

To report five patients who underwent lumbopleural (LPl) shunting for the treatment of idiopathic intracranial hypertension (IIH) and to describe the considerations, complications, and outcomes related to this rarely described procedure. ⋯ LPl shunting, though rarely used, is a viable option in the treatment of IIH refractory to standard peritoneal shunting. When pursuing this treatment, a valve and ASD are recommended to mitigate the risks of overdrainage and pleural effusion. Chest imaging should be obtained if the patient becomes symptomatic but can be deferred if the patient remains asymptomatic and is doing well.

Several studies have been conducted to identify the pathogenesis of and manage disk degeneration. To further this research, reliable animal models of disk degeneration are required. In the present study, a percutaneous technique is used to create a rabbit model of degenerative disk disease, and the reproducibility and efficacy of this technique is reported. ⋯ Our percutaneous technique provides a suitable rabbit model of degenerative disk disease to test the safety and efficacy of treatments for disk degeneration, such as stem cell transplantation.

Although the ventricular size is significantly reduced after endoscopic third ventriculostomy (ETV) in most successfully treated patients, ventricular size reduction is not always seen after a successful ETV. Practical and reliable radiologic parameters are still needed to assess the clinical success of an ETV. ⋯ The degree of reduction of the angle of the infundibular recess of the third ventricle correlated with the amount of third ventricular decompression after ETV. Most importantly, such a reduction was noted to occur during the early postoperative period when radiologic changes are less pronounced. Assessment of change in infundibular recess angle measurement is easy to perform and may prove helpful in cases with no clear-cut clinical evidence of success of ETV.
