We evaluated the relationship between sagittal spinopelvic parameters and the occurrence of adjacent vertebral fractures (AVF) and determined the possible risk factor. The most important factors for AVFs are the degree of osteoporosis and altered biomechanics due to the spinopelvic imbalance in the fractured area of the spine. ⋯ The most important factors for new VCFs after the initial compression fractures are the degree of osteoporosis and altered biomechanics due to the spinopelvic imbalance in the fractured area of the spine. Regarding the spinopelvic alignment to investigate the relationship with a subsequent AVF, segmental kyphotic angle, SS, LL, and SVA may be a potential predictor.

We reviewed all peer-reviewed papers analysing the cost-effectiveness of vertebroplasty and balloon kyphoplasty for osteoporotic vertebral compression fractures. In general, the procedures appear to be cost effective but are very dependent upon model input details. Better data, rather than new models, are needed to answer outstanding questions. ⋯ The cost-effectiveness of VAPs is uncertain. In answering the remaining questions, new cost-effectiveness analysis will yield limited benefit. Rather, studies that can reduce the uncertainty in the underlying data, especially regarding the long-term clinical outcomes of VAPs, should be conducted.

Bisphosphonates are commonly used in osteoporosis, but concerns have been raised about possible negative effects on fracture healing. We systematically reviewed the literature and found that bisphosphonates significantly prolong union times of distal radius fractures but not femoral fractures. The timing of bisphosphonate introduction does not affect fracture union time. ⋯ This systematic review has shown that bisphosphonates significantly prolong union times of distal radius fractures. Some clinical findings are in contrast with preclinical studies highlighting the need to develop better animal models to study osteoporosis, treatment and fracture healing. There is also a need for more well-constructed studies looking at the clinical effect of bisphosphonate on fracture healing in a large number of patients. These robust studies need to look at union time and non-union rates as a function of duration and dose of different bisphosphonates in different upper and lower limb fractures.

Lower body fat mass is a risk factor for bone loss at lumbar spine in postmenopausal women, but not in men. Body lean mass and fat mass were not associated with femoral neck bone loss in either gender. ⋯ Lower FM was an independent but modest risk factor for greater bone loss at the lumbar spine in women but not in men. If further studies confirm our findings, FM can help predict lumbar spine bone loss in women.

Multicenter Study
Relationship between American Society of Anesthesiologists (ASA) grade and 1-year mortality in nonagenarians undergoing hip fracture surgery.
This study retrospectively reviewed 327 nonagenarians who underwent hip fracture surgery at six hospitals. Functional status, postoperative complications, and 1-year mortality were evaluated, and relationships between these factors and American Society of Anesthesiologists (ASA) grade were analyzed. ASA grade was significantly associated with postoperative complications and 1-year mortality. ⋯ ASA grade was significantly associated with the rates of postoperative complications and 1-year mortality in nonagenarians undergoing hip fracture surgery. The preoperative functional status was also significantly associated with these outcomes.
