Biomechanical comparison of distal femoral fracture fixation: Polyaxial vs. uniaxial locking screws with different blocking screw configurations in retrograde femoral nailing.

Introduction: Clinical studies have indicated reduced reliance on blocking screws with the introduction of polyaxial locking nails, yet the biomechanical superiority of polyaxial locking over blocking screws remains unverified, specifically for distal dia-metaphyseal femur fractures.

Hypothesis: We hypothesized that the combination of multiaxial locking using three screws and parallel locking reinforced by two blocking screws would result in superior outcomes compared to utilizing only parallel locking with two screws and one blocking screw.

Materials And Methods: Third-generation custom-made femur models representing AO/OTA 32 A1.

Posteromedial plate application using medial midline incision for complex tibia plateau fractures: a retrospective study.

Background: Application of a posterior plate for tibia plateau fractures associated with posterior column involvement is becoming a widespread standard practice as previous studies have shown that additional fixation of the posterior column with a posteromedial buttress plate creates strongest fixation in terms of fracture stabilization This study evaluated the clinical and radiological results of patients undergoing surgery for complex tibial plateau fractures involving the posterior column with a posteromedial plate applied via a medial midline incision.

Methods: Medical records of patients undergoing surgery for Schatzker type IV, V, and VI tibia plateau fractures involving the posterior column in our institution were reviewed retrospectively. Patients with a follow-up of less than 1 year, pathological fractures, posterolateral column fractures requiring separate fixation, and open fractures were excluded from the study.

Biallelic Mutations in are Associated with Prenatal Polycystic Kidney Disease in a Turkish Family.

Polycystic kidney disease (PKD) is a life-threatening condition resulting in end-stage renal disease. Two major forms of PKD are defined according to the inheritance pattern. Autosomal dominant PKD (ADPKD) is characterized by renal cysts, where nearly half of the patients suffers from renal failure in the 7th decade of life.

Analytical design of discrete PI-PR controllers via dominant pole assignment.

In this study, a new discrete proportional integral-proportional retarded (D-PI-PR) controller design method is proposed. The proposed controller involves replacing the PD controller in the classical PI-PD control structure with a PR controller in discrete time and is implemented using dominant pole assignment, which is carried out by help of the modified Nyquist plot approach. The method starts with the determination of the controller parameters K and K in terms of the parameter K for a chosen delay parameter h after the computation of the desired dominant poles depending on the required closed-loop system performance criteria.
