Management
In a randomized controlled trial [PMID:36763817], no statistical difference was found between PCVP and UVP groups in terms of visual analog scale (VAS) scores for back pain over 12 months of follow-up.
The study [PMID:36763817] reported that PCVP techniques required a larger injection volume of polymethylmethacrylate (5.5 ± 1.4 mL) compared to UVP (4.2 ± 1.0 mL).
A prospective multicenter study [PMID:23429686] evaluated 362 patients treated conservatively without surgery, finding that interventions such as brace use, hospitalization duration, and post-injury bisphosphonate administration were associated with better outcomes in measures like SF-36 scores and activities of daily living.
Complications
Despite differences in cement distribution patterns noted in the PCVP group [PMID:36763817], the incidence of cement leakage was similar between the two techniques.
The research [PMID:23429686] utilized vertebral collapse as one of the primary response variables to evaluate the effectiveness of conservative treatment interventions in managing osteoporotic vertebral fractures.
Prognosis & Follow-up
The study [PMID:23429686] assessed patient outcomes 6 months post-fracture, indicating significant improvements in SF-36 physical component summary (PCS) and mental component summary (MCS) scores among conservatively managed patients.
