Few studies have evaluated the need for supplementary instrumentation after lumbar interbody fusion under the condition of whole body vibration (WBV) that is typically present in vehicles. This study aimed to determine the effect of posterior pedicle screw fixation on dynamic response of the whole lumbar spine to vertical WBV after transforaminal lumbar interbody fusion (TLIF). ⋯ After TLIF, application of BPSF can be helpful in the prevention of spine injury during vertical WBV.

Cerebrospinal fluid (CSF) leaks are a dreaded complication after surgery for tethered cord and are associated with significant patient morbidity. Although many strategies for managing postoperative CSF leaks exist, this problem is still daunting, especially in very young patients. In this study, we compared different management techniques for CSF leaks or significant pseudomeningocele in patients with tethered cord syndrome (TCS). ⋯ In carefully selected cases, CPS performed early after CSF leakage is highly successful with low morbidity. The primary closure can be attempted for low-pressure leaks without an associated pseudomeningocele.

Motor Cortex Stimulation Regenerative Effects in Peripheral Nerve Injury: An Experimental Rat Model.
Immediate microsurgical nerve suture remains the gold standard after peripheral nerve injuries. However, functional recovery is delayed, and it is satisfactory in only 2/3 of cases. Peripheral electrical nerve stimulation proximal to the lesion enhances nerve regeneration and muscle reinnervation. This study aims to evaluate the effects of the motor cortex electrical stimulation on peripheral nerve regeneration after injury. ⋯ MCS seems to have a beneficial effect after peripheral nerve injury and repair in terms of nerve regeneration and muscle reinnervation, especially when acute mode is used.

Review Case Reports
Cervical Periosteal Chondroma Causing Spinal Cord or Nerve Compression: 2 Case Reports and Literature Review.
Chondroma is a rare benign cartilaginous tumor that originates in chondrocytes and is commonly seen in the long bones; however, it infrequently occurs in the cervical spine. ⋯ The authors herein summarized 16 previous reports of cervical chondroma and compared the clinical courses and treatments. Recommended treatment included maximal surgical resection, especially when significant compression of the cervical cord and signal abnormality within the cord was observed. Annual postoperative follow-up is mandatory to ensure proper neurologic improvement.

Spontaneous Intraventricular Tension Pneumocephalus: Case Report and Review of the Literature.
Intracranial pneumocephalus is a well-known clinical entity most frequently caused by trauma and intracranial surgery. A less frequent cause of intracranial pneumocephalus is spontaneous pneumocephalus. Spontaneous pneumocephalus can have an intraventricular extension, causing tension intraventricular pneumocephalus. ⋯ This case demonstrates an unusual presentation of spontaneous intraventricular tension pneumocephalus necessitating ventriculostomy in addition to the traditional repair of a cerebrospinal fluid fistula.
