In acetabular fracture surgery, an infra-acetabular screw (IAS) is inserted from the anterior to the posterior column through the infra-acetabular corridor to stabilize both columns. Although the IAS is useful for increasing fixation strength, proper placement requires proficiency and often results in extraosseous screw penetration. The complex anatomy of the infra-acetabular corridor and difficult intraoperative detection of the ideal insertion point and angle make proper placement of the IAS challenging. This study aimed to detect the ideal insertion point and angle of the IAS based on anatomical landmarks that can be directly identified intraoperatively. ⋯ The IAS ideal insertion point detected as a distance from the pubic symphysis may aid in the proper insertion of the IAS during surgery. The insertion angle was parallel or tilted 10 ° laterally to the longitudinal axis in the pelvic outlet plane and almost perpendicular to the PIP in the sagittal plane when inserted from the ideal insertion point.

To compare the bone healing effects of percutaneously delivered bone marrow aspirate concentrate (BMC) versus reamer irrigator aspirator (RIA) suspension in a validated preclinical canine ulnar nonunion model. We hypothesized that BMC would be superior to RIA in inducing bone formation across a nonunion site after percutaneous application. The null hypothesis was that BMC and RIA would be equivalent. ⋯ Bone marrow aspirate concentrate (BMC) had important advantages over Reamer Irrigator Aspirator (RIA) suspension for percutaneous augmentation of bone healing in a validated preclinical canine ulnar nonunion model based on clinically relevant radiographic and histologic measures of bone formation.

Dog bite injuries are a preventable yet common cause of animal related hospitalisation. Dog bites in metropolitan areas have been well characterised however there is limited information regarding dog bites in regional areas. This study sought to describe the demographics, clinical presentation and short-term outcomes of patients presenting with dog bite related injuries to Broome Regional Hospital (BRH). ⋯ Dog-bite trauma is common and consumes significant health resources associated with ED presentations, hospital admissions, theatre usage and transfer in severe cases. A multifaceted approach encompassing education, engineering, and enforcement is required to prevent dog bites.

In this study, the effects of topical sildenafil applications on oxidative damage levels and antioxidative metabolism and their contribution to wound healing and treatment were investigated. ⋯ The study findings indicated that topical application of sildenafil led to noteworthy alterations in serum and tissue antioxidative metabolism as well as oxidative damage levels among rats with induced wounds. Sildenafil may be useful in wound treatment; it has been concluded that it is capable of directing new studies to be carried out.
