Vertebral compression fractures (VCF) due to osteoporotic degeneration and metastatic disease represent an increasingly significant public health problem. Percutaneous vertebroplasty (VP) began as a simple, low-cost procedure that aimed to provide pain relief for patients with VCF. Balloon kyphoplasty (KP) was introduced later, and was presented not only as a "pain killer," but also as a deformity correction procedure. ⋯ However, vertebral augmentation may be beneficial in patients with comorbidities that make prolonged bed rest dangerous, in patients with fractures that fail to heal, and in patients with painful VCF due to metastatic disease. Patient selection should be based on a combination of clinical and radiological indications. We review recent studies in the extensive literature on vertebral augmentation, with the goal of clarifying some of the controversy surrounding these procedures.

The purpose of this study was to assess the clinical and radiological outcomes of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) surgery for lumbar spondylolisthesis. A prospective analysis was conducted of 23 consecutive patients with grade I or grade II lumbar spondylolisthesis who underwent a MI-TLIF using image guidance between August 2008 and September 2010. The patient group comprised 13 males and 10 females (mean age 57 years), 22 of whom underwent single level fusion and one patient with a two level fusion. ⋯ There were no occurrences of infection and no postoperative cerebrospinal fluid leaks. We conclude that MI-TLIF offers patients a safe and effective surgical option for lumbar spondylolisthesis treatment. Furthermore, it may offer patients additional advantages in terms of postoperative pain and recovery.

Dehiscence after a wound has healed is a known complication of craniotomy for tumor resection. We conducted a retrospective analysis of 64 patients who underwent craniotomy for tumor resection followed by radiation or radiosurgery between 2006 and 2010. ⋯ These treatments may be risk factors for developing delayed dehiscence and, in combination, may potentiate local wound healing problems. Potential mechanisms and management strategies are discussed.

Randomized Controlled Trial
A prospective study of Gasserian ganglion pulsed radiofrequency combined with continuous radiofrequency for the treatment of trigeminal neuralgia.
We conducted a prospective randomized controlled study to evaluate whether continuous radiofrequency (CRF) combined with pulsed radiofrequency (PRF) to the Gasserian ganglion (GG) decreases the side effects of CRF while preserving efficacy. Sixty patients diagnosed with classic trigeminal neuralgia (TN) were treated with either 75°C CRF for 120 s to 180 s (SCRF group), 75°C CRF for 240 s to 300 s (LCRF group), or 42°C PRF for 10 minutes (min) followed by 75°C CRF for 120 s to 180 s (PCRF group). Patients were assessed for pain intensity, quality of life (QOL), and intensity of facial dysesthesia before (baseline), and at seven days, three months, six months, and 12 months after the procedure. ⋯ After 12 months, >70% of patients in each group had complete pain relief, and the QOL in all three groups had increased significantly compared to baseline. The intensity of facial dysesthesia was mildest in the SCRF group and most severe in the PCRF group on the seventh day after the procedure, but most persistent in the LCRF group. Patients who receive PRF combined with CRF to the GG can achieve comparable pain relief to those who receive CRF alone, and shorter exposure of CRF could result in less destruction of the target tissue.

It has been found that the hemostatic system is activated following a brain injury. To explore the role of D-dimer in spontaneous intracerebral hemorrhage (ICH), this prospective study aimed to evaluate the association between serum D-dimer concentration, clinical outcome and radiographic findings of ICH patients in the emergency department (ED). ⋯ Diabetes mellitus (odds ratio [OR]: 2.93; 95% confidence interval [CI]: 1.1-7.76, p=0.031), ICH volume (OR: 1.16; 95% CI: 1.07-1.27, p<0.0001) and D-dimer concentration (OR: 2.72; 95% CI: 1.08-6.9, p=0.002) were associated with 30-day mortality. This study shows that in patients with spontaneous ICH, a higher initial D-dimer concentration is associated with higher 30-day mortality.
