Review Meta Analysis
Unilateral versus bilateral balloon kyphoplasty for osteoporotic vertebral compression fractures.
Osteoporotic vertebral compression fractures (VCFs) commonly occur in aged people. Balloon kyphoplasty (KP) has been proven to be efficacious for pain relief and reduction of vertebral height for patients with osteoporotic VCFs. However, very little is known about the comparison of clinical and radiographic outcomes between unilateral and bilateral balloon KP in treating this kind of patients. ⋯ The efficacy of both unilateral and bilateral balloon KP to provide rapid, significant, and sustained pain relief for patients with osteoporotic VCFs is validated. Unilateral balloon KP is a reasonable treatment for patients with osteoporotic VCFs considering that it could achieve equivalent pain relief with less surgery time and PMMA consumption compared to bilateral balloon KP. There was no evidence to prove that unilateral balloon KP results in higher incidence of PMMA leakage than bilateral balloon KP. Although unilateral balloon KP was less efficacious in the reduction of fractured vertebral body, it is still unclear if the clinical results of balloon KP were positively correlated with the restoration of vertebral height and amount.

Meta Analysis Comparative Study
Comparing pain reduction following vertebroplasty and conservative treatment for osteoporotic vertebral compression fractures: a meta-analysis of randomized controlled trials.
Osteoporotic vertebral compression fractures (OVCFs) are the most common osteoporotic fractures. Pain is the main symptom. Percutaneous vertebroplasty (PVP) is a therapeutic procedure performed to reduce pain in vertebral compression fractures. Numerous case series and several small, non-blinded, non-randomized controlled studies have suggested that vertebroplasty is an effective means of relieving pain from osteoporotic fractures. However, a recent pooled analysis from 2 multicenter randomized controlled trials concluded that the improvement in pain afforded by PVP was similar to placebo. ⋯ PVP has some value for relieving pain; however, the possibility of a placebo effect should be considered. PVP has gained acceptance as a complementary treatment when conservative management has failed before its benefits have been fully understood. More large scale, double blinded, controlled trials are necessary in order to quantify the pain relief afforded by PVP more precisely.

Randomized Controlled Trial
Concordant pressure paresthesia during interlaminar lumbar epidural steroid injections correlates with pain relief in patients with unilateral radicular pain.
Transforaminal and interlaminar epidural steroid injections are commonly used interventional pain management procedures in the treatment of radicular low back pain. Even though several studies have shown that transforaminal injections provide enhanced short-term outcomes in patients with radicular and low back pain, they have also been associated with a higher incidence of unintentional intravascular injection and often dire consequences than have interlaminar injections. ⋯ This study showed that the lateral parasagittal interlaminar approach was more effective than the midline interlaminar approach in targeting low back pain with unilateral radicular pain secondary to degenerative lumbar disc disease. It also showed that pressure paresthesia occurring ipsilaterally during an LESI correlates with pain relief and may therefore be used as a prognostic factor.

Randomized Controlled Trial
A randomized, double-blind, active-controlled trial of fluoroscopic lumbar interlaminar epidural injections in chronic axial or discogenic low back pain: results of 2-year follow-up.
Chronic low back with or without lower extremity pain is extremely common, expensive, and disabling. However, all modalities of treatments are directed towards disc herniation which is responsible for a very small proportion of the patients. Thus, chronic low back pain without disc herniation is common. Multiple modalities of treatments are utilized in managing axial or discogenic pain including surgery and epidural injections including surgery, intradiscal therapies, and epidural injections. However, there is continued debate on the effectiveness, indications, and medical necessity of all modalities treatments in managing axial or discogenic pain in the lumbar spine. ⋯ Lumbar interlaminar epidural injections of local anesthetic with or without steroids are effective in patients with chronic axial low back pain of discogenic origin without facet joint pain, disc herniation, and/or radiculitis.
