Percutaneous sacroplasty is a procedure adapted from vertebroplasty, which is designed to ameliorate the painful morbidity associated with sacral insufficiency fractures without the invasiveness of open surgery. Early estimates of efficacy, according to several case reports and small series, appear promising, but the procedure is not without risk. Several cases of radiculopathy due to nerve root compression by extravasated polymethylmethacrylate (PMMA) have been reported. The authors present a case of radiculopathy caused by cement leakage from sacroplasty, treated with surgical decompression of the compromised nerve root...

BACKGROUND AND PURPOSE: Currently, the effect of the volume of cement used during sacroplasty on the restoration of pelvic strength and stiffness is unknown. The purpose of this study was to measure that effect in a sacral insufficiency fracture model. MATERIALS AND METHODS: Twenty-five osteoporotic cadaveric pelves were potted, and sacral fractures were produced. Specimens were divided into 4 groups: group 0 + 0 (control), no sacroplasty; group 3 + 0, sacroplasty (posterior approach), 3 mL of a bone cement injected bilaterally into the fracture site at S1; group 3 + 3, sacroplasty (posterior approach), 3 mL of the same cement injected bilaterally into the fracture site at S1 and S2; and group 6 + 3, sacroplasty (posterior approach), 6 mL of the same cement injected bilaterally at S1 and 3 mL injected bilaterally at S2...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
