Risk factors for new vertebral fractures after percutaneous vertebroplasty in patients with osteoporosis: a prospective study.

Purpose: To determine the risk factors for new vertebral compression fractures (VCFs) following percutaneous vertebroplasty (PV) in patients with osteoporosis.

Materials And Methods: This prospective study included 132 consecutive patients with osteoporosis treated with PV in a single institution over 46 months from March 2005 to December 2008. Multivariable logistic regression and univariate analysis were employed to identify risk factors for new VCFs after PV, including patient demographic data, parameters of the initial and new fractured vertebrae, procedure-related information, and follow-up data.

[Influencing factors of long-mid term efficacy following percutaneous vertebroplasty in patients with osteoporosis].

Objective: To determine the therapeutic efficacy and the influencing factors for the long/middle-term outcomes of percutaneous vertebroplasty (PVP) in the treatment of painful osteoporotic vertebral compression fractures (OVCFs).

Methods: This prospective study recruited a total of 131 consecutive OVCF patients treated with PVP at a single institution from March 2005 to December 2009. There were 106 females and 25 males.

Long-term outcomes of patients with lumbar disc herniation treated with percutaneous discectomy: comparative study with microendoscopic discectomy.

We assessed the long-term outcomes of patients with lumbar disc herniation treated with percutaneous lumbar discectomy (PLD) or microendoscopic discectomy (MED). A retrospective study was performed in consecutive patients with lumbar disc herniation treated with PLD (n = 129) or MED (n = 101) in a single hospital from January 2000 to March 2002. All patients were followed up with MacNab criteria and self-evaluation questionnaires comprising the Oswestry Disability Index and Medical Outcomes Study 36-Item Short-Form Health Survey.

[Long-term outcomes of percutaneous lumbar discectomy and microendoscopic discectomy for lumbar disc herniation].

Objective: To evaluate the long-term effects of percutaneous lumbar discectomy (PLD) and microendoscopic discectomy (MED) in treatment of lumbar disc herniation.

Methods: A questionnaire survey by letter and telephone was conducted among 104 patients undergoing PLD and 82 patients undergoing MED during January 2000 to March 2002, to investigate the Oswestry disability index (ODI), Short Form-36 (SF-36) score, and Japanese Orthopedic Association (JOA) score.

Results: The excellent/good rate (ODI score=0-20%) of the MED group was 79.
