Conservative treatment of fragility fracture of the pelvis: A retrospective study.

Background: Although an increasing number of studies have reported the usefulness of early minimally invasive surgery (MIS) or fragility fracture of the pelvis (FFP), MIS is difficult to perform in every hospital, partly because of equipment problems. Moreover, different opinions exist on FFP treatment methods and the indication for surgery is usually determined by the fracture type. Since our hospital follows a conservative approach as the basic treatment, this study examined the outcomes of such an FFP approach.

Delayed surgery after hip fracture affects the incidence of venous thromboembolism.

Background: Venous thromboembolism (VTE) is one of the most common complications of hip fracture surgeries, and it is unclear whether delayed surgery affects the incidence of VTE. This study aimed to examine the association between delayed surgery and VTE incidence by statistically adjusting for factors that may influence VTE incidence.

Methods: We included 862 patients ≥ 65 years with hip fractures who underwent surgery between October 2010 and December 2020.

Minimally invasive surgery technique for unstable pelvic ring fractures with severe vertical shear displacement: A retrospective study.

Background: Unstable pelvic fractures, especially vertical shear fractures, require surgery for correct reduction, rigid fixation, and improved postoperative outcomes. Herein, we assess the effectiveness of our minimally invasive procedure for the management of unstable pelvic fractures.

Hypothesis: We hypothesized that this procedure would be useful for the management of unstable pelvic fractures.

Relationship between site-specific bone mineral density in the proximal femur and instability of proximal femoral fractures: A retrospective study.

Background: Proximal femoral fractures can occur in patients with osteoporosis. However, the relationship between bone mineral density (BMD) of the proximal femur and fracture type and instability remains unclear. This study aimed to determine whether there is a relationship between the site-specific BMD of the proximal femur and the instability of proximal femoral fracture.

Retrospective high volume comparative study suggests that patients on aspirin could have immediate surgery for hip fractures without significant blood loss.

Purpose: This study aimed to investigate the effects of aspirin on peri-operative hidden blood loss during hip fracture surgery by adjusting for possible factors affecting blood loss using a propensity score matching method.

Methods: We retrospectively collected data from a cohort of isolated hip fracture patients (aged ≥ 65 years)who underwent surgery from January 2010 to December 2019. The study's primary outcome was blood loss from admission to the day after surgery in the aspirin and control groups.

Minimally Invasive Surgery for Unstable Pelvic Ring Fractures: Transiliac Rod and Screw Fixation.

Pelvic fractures occur with high-energy trauma, and the patient's clinical status is unstable. Although a number of surgical methods for unstable pelvic fractures are available, none can achieve strong fixation with minimal invasiveness. We describe a surgical transiliac rod and screw fixation (TIF) procedure that provides minimally invasive fixation using a spinal implant for unstable pelvic ring fractures, and we retrospectively analyzed the procedure's outcomes in 27 patients with type B or C1 fractures (based on the AO/ATO classification system).

The Effect of the Cervical Orthosis on Swallowing Physiology and Cervical Spine Motion During Swallowing.

Cervical orthosis is used to immobilize the neck in various disorders such as trauma and post-operation. However, it is still uncertain how cervical orthosis restricts the degree of movement of the cervical spine during swallowing and how they affect swallowing physiology. The purpose of this study was to evaluate these issues using the Philadelphia(®) Collar.

Pathogenesis and diagnosis of delayed vertebral collapse resulting from osteoporotic spinal fracture.

Background Context: In recent years there have been an increasing number of reports on surgical cases involving delayed neurological deficits caused by vertebral collapse after osteoporotic vertebral fracture.

Purpose: We do not yet know which patients are most susceptible to delayed vertebral collapse and subsequent neurological deficits, or whether this pathological condition can be prevented or predicted. In this study, we investigated the mechanism of progression and radiographic features characteristic of this disease, and we report here the predictive or risk factors for delayed osteoporotic vertebral collapse.
