An orthogeriatric collaborative intervention program for fragility fractures: a retrospective cohort study.

Background: This retrospective cohort study aims to investigate the impact of regular pre- and postoperative geriatric input into the management of geriatric patients with hip fracture, with specific interests in morbidity and mortality.

Methods: Patients with hip fracture (n = 548) older than 60 years were identified within a 2-year period. In the first year, the patients (n = 270) were managed mainly by orthopedics and this group constituted the control group.

Outcomes and satisfaction of patients with orthopaedic implants left in-situ for more than three years: a retrospective study.

Background: There are no clear guidelines on implant removal. Few have assessed the long-term outcomes of patients with implants left in-situ, or removed. Therefore, removal of implants after fracture fixation remains controversial.

Three-dimensional high frequency power Doppler ultrasonography for the assessment of microvasculature during fracture healing in a rat model.

We aimed to establish a novel approach with 3D high frequency power Doppler ultrasonography (3D-HF-PDU) to assess microvasculature at the fracture site in rat femurs by comparing with microCT-based microangiography. Twenty-four 9-month-old ovariectomized (OVX) osteoporotic rats and age-matched sham-ovariectomized (Sham) rats were used for establishing closed fracture models on right femora. At 2, 4, and 8 weeks post-operatively, four rats in each group underwent in vivo 3D-HF-PDU scanning for evaluation of vascularization and blood flow at the fracture site.

Low-magnitude high-frequency vibration (LMHFV) enhances bone remodeling in osteoporotic rat femoral fracture healing.

Low-magnitude high-frequency vibration (LMHFV) (35 Hz, 0.3 g) accelerates fracture healing by enhancing callus formation and mineralization for both normal and osteoporotic rats in our previous studies.1,2 We hypothesized that LMHFV enhances fracture healing through bone remodeling.

Low-magnitude high-frequency vibration treatment augments fracture healing in ovariectomy-induced osteoporotic bone.

Fracture healing is impaired in osteoporotic bone. Low-magnitude high-frequency vibration (LMHFV) has recently been proven to be osteogenic in osteoporotic intact bone. Our previous study found that LMHFV significantly enhanced fracture healing in adult rats.
