To investigate the clinical characteristics, treatment, and outcomes of chronic subdural hematomas (CSDH) in young patients. ⋯ Headache is the most common symptom, and AC/V-P shunts are risk factors of CSDH in young patients. AC/V-P shunt-associated CSDH is associated with younger morbidity. Head trauma is a risk factor for AC/V-P shunt-associated CSDH, but is not significance in patients without AC/V-P shunts. Catheter drainage through a burr hole may be the first-choice surgical procedure in treatment of CSDH in young patients, including AC/V-P shunt-associated CSDH.

Cavernous sinus hemangiomas (CSHs) are rare vascular tumors. Stereotactic radiosurgery is an effective treatment for small CSHs. The optimal treatment for giant CSHs is controversial. This study reports advantages of a complete intradural transcavernous approach in total resection of CSHs. ⋯ Surgical total resection is the primary and reasonable choice for giant CSHs. Microsurgical resection of giant CSHs through a completely intradural transcavernous approach is an alternative treatment option for giant CSHs.

To compare the outcome of anterior cervical decompression and fusion (ACDF) and posterior laminoplasty (LAMP) for treating 4-level cervical spondylotic myelopathy (CSM). ⋯ Both ACDF and LAMP were effective in the treatment of multilevel CSM. Compared with LAMP, ACDF is less invasive and may be more suitable for elderly patients with poor tolerance of surgery.

Computer-assisted three-dimensional navigation often guides spinal instrumentation. Optical topographic imaging (OTI) offers comparable accuracy and significantly faster registration relative to current navigation systems in open posterior thoracolumbar exposures. We validate the usefulness and accuracy of OTI in minimally invasive spinal approaches. ⋯ OTI is a novel navigation technique previously validated for open posterior exposures and in this study has comparable accuracy for mini-open minimally invasive surgery exposures. The likelihood of successful registration is affected more by the geometry of the exposure than by its size.

Percutaneous Doxycycline Foam Injections, A Novel Treatment Method for Vertebral Aneurysmal Bone Cysts.
Aneurysmal bone cysts (ABCs) are among the most aggressive benign bone tumors, often occurring in both long bones and the spine. Treatment remains controversial as recurrence rates continue to be high. Treatment options include curettage with or without bone grafting, arterial embolization, en block resection with or without instrumentation or arthrodesis, radiation, and intralesional drug injections (steroids, calcitonin, doxycycline). ⋯ At the 1-year follow up appointment, all symptoms had been resolved. Repeat computed tomography and magnetic resonance imaging demonstrated that the ABC had nearly filled in completely with new bone. Our case demonstrates successful use of this percutaneous, less invasive method in the management of vertebral ABCs.
