Introduction: Minimal invasive fixation of fragility pelvic fracture is feasible with advancement of computerized navigation. However, the clinical outcomes compared with conservative care were seldom mentioned. Method: This is a retrospective study comparing the outcomes of elderly with stable pelvic fracture treated conservatively or operatively using computerized navigation. Outcome parameters included pain score, analgesics requirement, length of hospital stay and complication(s), if any. Result: Operations were performed in 15 patients from July 2017 to November 2018. A retrospective cohort of 37 patients who were treated conservatively was recruited. In the operative group, it showed a statistically significant reduction in analgesics consumption at 4-week time only. There was significant improvement in pain score at 1-week, 4-week and 3-month time. Patients showed earlier return to premorbid walking status. No major surgical complication was noted. Conclusion: Treating fragility pelvic fracture with computerized navigated screw fixation achieve better pain control, reduction in analgesics requirement and earlier mobilization.

Osteoporotic spine fracture is very common nowadays due to the aging population. It may result in prolonged immobilization due to significant back pain. Cement vertebroplasty helps to relieve pain, provides immediate stability and allows early mobilization. Intraspinal leakage of cement is a rare complication but it may lead to catastrophic neurological injuries. Evidence-based management guidelines for this complication are lacking. This is a case report about intraspinal leakage of cement during vertebroplasty for an 85-year-old woman with osteoporotic burst fractures over the lumbar spine. Urgent exploration and decompression was performed. No neurological injury was found after the operation and the patient recovered from osteoporotic back pain uneventfully.
