Early Clinical Outcomes of Polyaxial Locking Cap Plate Fixation for Fixation of Displaced Olecranon Fractures.
Arch Bone Jt Surg
January 2025
Clinical Orthopaedic Surgery, Shoulder & Elbow Division, University of Pennsylvania, Philadelphia, Pennsylvania, USA.
Objectives: The purpose of this study is to evaluate the outcomes of a polyaxial locking plate utilizing locking-cap fixation for treatment of patients with displaced olecranon fractures.
Methods: A retrospective review was performed for all consecutive patients at two institutions with displaced olecranon fractures treated with a polyaxial locking plate. Patients were required to have at least 1-year follow up.
Three-Dimensional CT for Preprocedural Planning of PCI for Ostial Right Coronary Artery Lesions: A Randomized Controlled Pilot Trial.
Circ Cardiovasc Interv

Background: Geographic stent-ostium mismatch is an important predictor of target lesion failure after percutaneous coronary intervention of an aorto-ostial right coronary artery lesion. Optimal visualization of the aorto-ostial plane is crucial for precise stent implantation at the level of the ostium. This study investigates whether preprocedural 3-dimensional computed tomography (3DCT), with determination of the optimal viewing angle, would allow for more precise stent implantation and reduce procedure time, contrast, and radiation dose.

Radiation Safety and Quality Assurance division, National Cancer Center Hospital East, Chiba, 277-8577, Japan.
The impact of three-dimensional (3D) dose delivery accuracy of C-arm linacs on the planning target volume (PTV) margin was evaluated for non-coplanar intracranial stereotactic radiosurgery (SRS). A multi-institutional 3D starshot test using beams from seven directions was conducted at 22 clinics using Varian and Elekta linacs with X-ray CT-based polymer gel dosimeters. Variability in dose delivery accuracy was observed, with the distance between the imaging isocenter and each beam exceeding 1 mm at one institution for Varian and nine institutions for Elekta.

Objective: The study aimed to evaluate the accuracy and safety of the semi-active robotic system for implant placement in atrophic posterior maxilla.
Methods: Patients underwent robot-assisted implant placement in atrophic posterior maxilla were identified and included. Cone-beam computed tomography (CBCT) was performed before surgery.
[Treatment with TOPS for short femoral stump].
Oper Orthop Traumatol
January 2025
Klinik für Unfall‑, Hand und Wiederherstellungschirurgie, Universitätsmedizin Rostock, Schillingallee 35, 18057, Rostock, Deutschland.
Objective: Treatment with transcutaneous osseointegrated prosthesis systems (TOPS) for short femoral amputation stumps aims to restore independent walking ability after proximal femoral amputation by direct bone-guided prosthesis anchorage. This cannot be safely achieved with conventional socket prostheses due to the mechanically inadequate socket contact surface.
Indications: Treatment of patients with short transfemoral stumps who cannot be mobilized sufficiently with conventional socket prostheses.
