Balloon-assisted kyphoplasty (BAK) is a well-accepted treatment for symptomatic vertebral compression fractures (VCF) secondary to osteoporosis. Some have raised a concern of an increased incidence of adjacent fractures due to alterations in spine biomechanics after cement augmentation. The incidence of subsequent VCFs following BAK is poorly understood. The aim of this study was to investigate the timing, location, and incidence of new VCFs following BAK and to identify risk factors associated specifically with the occurrence of new adjacent level fractures. ⋯ Symptomatic compression fractures after BAK are relatively uncommon and may occur long after the initial kyphoplasty procedure. Only half of subsequent fractures occur immediately adjacent to the initially treated level; the others occur remotely. Patients with a single symptomatic thoracic or lumbar fracture suffered from remote and adjacent level fractures equally. In contrast, all patients who suffered both a thoracic and lumbar fracture at the same time had a second fracture at an adjacent level. Specific risk factors for remote versus adjacent level fractures could not be determined. Key words: Balloon kyphoplasty, cement augmentation, osteoporosis, vertebral compression fracture, adjacent level fracture, vertebroplasty.

Review Meta Analysis
Can Unilateral Kyphoplasty Replace Bilateral Kyphoplasty in Treatment of Osteoporotic Vertebral Compression Fractures? A Systematic Review and Meta-analysis.
Kyphoplasty has been proven to be an efficient method to relieve patient suffering from osteoporotic vertebral compression fractures (OVCFs). Because of its technological superiority, unilateral kyphoplasty consumes less operative time and bone cement than traditional bilateral kyphoplasty. However, there is controversy about which method is most efficient in the treatment of OVCFs. Thus, an overall analysis should be performed to shed light on the facts corroborating both procedures. ⋯ Both unilateral kyphoplasty and bilateral kyphoplasty are safe and effective treatments for OVCFs. However, when operative time, cement volume, cement leakage, short-term general health, radiation dose, and hospitalization costs are taken into consideration, unilateral kyphoplasty may be the better choice. Yet, more high-quality RCTs with long-term follow-up are still required to make the final conclusion.Key words: Kyphoplasty, unilateral approach, bilateral approach, osteoporotic vertebral compression fractures, meta-analysis.

Randomized Controlled Trial
Analgesic Effect of Nalbuphine When Added to Intravenous Regional Anesthesia: A Randomized Control Trial.
Different adjuvant drugs are currently added to lidocaine for intravenous regional anesthesia (IVRA) to decrease tourniquet and postoperative pain. ⋯ Nalbuphine decreases early tourniquet and postoperative pain after IVRA and delays the need for analgesic rescue. In addition, nalbuphine accelerates the onset and prolongs the recovery time for both sensory and motor blocks with no significant adverse events. However, it has no effect on postoperative cortisol levels.Key words: Intravenous, regional anesthesia, lidocaine, nalbuphine, pain, postoperative.

Observational Study
Cervical Interlaminar Epidural Injections at High Doses Do Not Increase Optic Nerve Sheath Diameter on a Long-Term Basis.
Cervical epidural injection (CEI) is widely performed on patients with pain originating from the cervical spine. Studies have shown a good relationship between the optic nerve sheath diameter (ONSD) and the intracranial pressure (ICP). ⋯ Registered in the Clinical Research Information Service of the Korea National Institute of Health, registration number: KCT0001487. Key words: Analgesic techniques, epidural block, intracranial pressure, optic nerve sheath diameter, ultrasonography Analgesic techniques, epidural block, intracranial pressure, optic nerve sheath diameter, ultrasonography.

Open lumbar microdiscectomy (OLM) has been considered the gold standard in the management of lumbar disc herniation (LDH) for its favorable outcomes in long-term follow-up. Nowadays, percutaneous endoscopic lumbar discectomy (PELD) is gaining recognition. However, greatest limitation of studies of PELD is the lack of long-term follow-up outcomes. ⋯ PELD has favorable long-term outcomes.Key words: Long-term, PELD, endoscopic lumbar discectomy, revision rate, disc height, instability.
