Comparative Study
Comparative assessment of different percutaneous endoscopic interlaminar lumbar discectomy (PEID) techniques.
Percutaneous endoscopic lumbar discectomy is a common surgical treatment for lumbar disc herniation, and percutaneous endoscopic interlaminar lumbar discectomy (PEID) is commonly used for direct decompression of L5-S1. Like microdiscectomy, recurrence of herniation after endoscopic discectomy is an important problem. In this study, we aimed to decrease the recurrence after PEID using a new surgical technique. ⋯ Though a learning curve is needed in order to become familiar with PEID, recurrence after PEID was associated with advanced age, and PEID with annular sealing resulted in lower early recurrence rates than without annular sealing. Thus, PEID with annular sealing may be a useful technique for reducing early recurrence.

Vertebroplasty (VP) and kyphoplasty (KP) are emerging procedures for almost immediate pain relief when treating osteoporotic or osteolytic fractures. The main reported complication is polymethylmethacrylate (PMMA) leakage, which may lead to compression of neural structures or embolism. Different authors have proposed that intravertebral pressure (IP) is an important factor determining the risk for leakage, although so far only limited information has been gathered from clinical and experimental studies. There is also a lack of understanding of the IP during conventional interventions in VP and KP in the clinic. ⋯ This study showed that the IP of compressed vertebrae was significantly higher than that of adjacent normal vertebrae. There was a significant increase in IP during the PMMA filling in VP and KP; the IP of compressed vertebrae was not significantly reduced by the balloon inflation in KP, and no statistically significant differences in IP were found during all common stages of PMMA filling in VP and KP.

Cervical central stenosis (CCS) is a narrowing of the spinal canal that can cause mechanical compression of the spinal nerve and roots, leading to neck pain and/or radicular pain. Cervical epidural steroid injections are commonly used in the treatment of CCS. After failure of epidural steroid injections, the next sequential step is percutaneous adhesiolysis with a targeted drug delivery. ⋯ Percutaneous adhesiolysis utilizing local anesthetic steroids and hypertonic sodium chloride solution may be an effective management strategy in patients with chronic posterior neck and upper extremity pain due to cervical central spinal stenosis, although there is no correlation between therapeutic response and the grade of CCS.

Among the many diagnostic and therapeutic interventions available for the management of chronic pain, epidural steroid injections are one of the most commonly used modalities. The explosive growth of this technique is relevant in light of the high cost of health care in the United States and abroad, the previous literature assessing the effectiveness of epidural injections has been sparse with highly variable outcomes based on technique, outcome measures, patient selection, and methodology. However, the recent assessment of fluoroscopically directed epidural injections has shown improved evidence with proper inclusion criteria, methodology, and outcome measures. The exponential growth of epidural injections is illustrated in multiple reports. The present report is an update of the analysis of the growth of epidural injections in the Medicare population from 2000 to 2011 in the United States. ⋯ Epidural injections in Medicare recipients increased significantly. The growth was significant for some specialties (radiology, physical medicine and rehabilitation, and psychiatry) and for certain procedures (lumbosacral transforaminal epidural injections).

The clinical management of osteolytic metastases involving C2 is unique, because it is challenging to approach these lesions. Symptoms may vary from local pain to progressive neurological deficit. Surgery or radiotherapy have been the treatments of choice for several years; however, surgery may not bean option for patients with multiple metastases and poor general medical status, and radiotherapy carries the risk of vertebral collapse and consequent neural compression due to delayed bone reconstruction. Through different approaches, vertebroplasty has been introduced into clinical practice as an alternative to traditional surgical and radiotherapy treatments of osteolytic metastases at C2. ⋯ Vertebroplasty via an anterolateral approach is an effective technique to treat osteolytic metastases involving C2. It is a valuable, minimally invasive, and efficient method that allows quick and lasting resolution of painful symptoms.
