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.

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.
