Purpose: Little scientific evidence on blood loss and transfusion rates after short-stem hip arthroplasty exists. The hypothesis of this study was that the blood loss and transfusion rate is lower in short stems compared to straight stems.

Methods: We compared 124 patients who underwent total hip arthroplasty (THA) using a short-stem design (group 1) and 141 patients using a straight-stem design (group 2). All patients were operated on by the same surgeon, and both groups were similar in age, gender, affected side, body mass index, and ASA score.

Results: The calculated blood loss was 1139 ml in group 1 and 1358 ml in group 2 (p < 0.001). The transfusion rate was 8% in group 1 and 15.6% in group 2 (p < 0.001). There was no significant difference between groups 1 and 2 regarding complications and operation time (p > 0.05).

Conclusion: Compared to patients after straight stem THA, both blood loss and blood transfusion rates were lower in patients after short stem THA.

Objective: Intraventricular hemorrhage (IVH) is a serious condition with high mortality rates and poor functional outcome in survivors. Treatment includes external ventricular drains (EVDs), which are associated with several complications. This study reports the clinical outcome and complication rate in patients with primary IVH (pIVH) and secondary IVH treated with EVDs.

Objective: Pediatric traumatic brain injury (TBI) represents a significant public health concern and source of resource utilization. The aim of this study was to establish the ability of the previously published pediatric Brain Injury Guidelines (pBIG) to identify patients with traumatic intracranial hemorrhage (ICH) who might not require routine repeat neuroimaging, neurosurgical consultation, or hospital admission in a large level I and level II trauma cohort.

Methods: Pediatric patients who presented with traumatic ICH between 2018 and 2022 at the included institutions were retrospectively reviewed and sorted into pBIG categories using clinical and radiographic criteria.

Purpose: Proliferative vitreoretinopathy (PVR) is the leading cause of surgical failure following rhegmatogenous retinal detachment (RRD). In this study, we aimed to explore ocular and systemic risk factors for PVR due to RRD in a large patient database.

Methods: Patients who have a diagnosis of RRD and PVR, and who have been seen in the last seven years prior to analysis (January 2015-February 2023) were identified in the Vestrum Health database.
