Background: Cardiac resynchronization therapy (CRT) is a recognized treatment for severe heart failure. The recommended left ventricular (LV) lead position is at the lateral or posterolateral wall. However, LV leads cannot always be implanted at the expected site. The aim of our study was to describe in a large series of patients the anatomical position really achieved by LV leads at implant.
Method: In consecutive patients referred for CRT, we determined the LV lead implantation success rate, the success rate for the initial target vein, and the final position achieved by the tip of the LV lead in the left and right anterior oblique projections.
Results: Ninety patients (66 men, 71 +/- 9 years, 20% New York Heart Association (NYHA) class IV) were referred for an LV lead implantation between September 2003 and March 2006. A LV lead could be implanted in 92% of patients. In 70%, LV leads were implanted in the initial target vein. The final location was lateral or posterolateral in 68% and anterior or anterolateral in 32% of patients. The mean procedural time was 117 +/- 42 minutes.
Conclusions: LV lead implantation was achieved in 92% of patients with mean procedure duration of less than 2 hours. Nevertheless, 30% of LV leads were implanted outside of the initial target vein and 32% at the anterior or anterolateral wall. Further studies are warranted to compare the responder rate to CRT when the LV lead is at the lateral or posterolateral wall or when the LV lead is at an alternative site.

Hinge Position Dominance Over Osteotomy Inclination in Medial Open-Wedge High Tibial Osteotomy: A Key Factor in Posterior Tibial Slope Changes.

January 2025
Department of Biomedical Engineering, University of Twente, Enschede, The Netherlands.
Objective: A medial open-wedge high tibial osteotomy (MOWHTO) may increase the posterior tibial slope (PTS). The purpose of this study was to determine the effect of the osteotomy inclination angle (in the sagittal plane) in combination with different hinge positions (in the transverse plane) on the change in PTS due to a MOWHTO.
Methods: We developed a mathematical approach to determine the effect of the osteotomy inclination angle combined with different hinge positions.

Since clinical features of chronic muscle pain originating from the low back and limbs are different (higher prevalence and broader/duller sensation of low back muscle pain than limb muscle pain), spinal and/or supraspinal projection of nociceptive information could differ between the two muscles. We tested this hypothesis using c-Fos immunohistochemistry combined with retrograde-labeling of dorsal horn (DH) neurons projecting to ventrolateral periaqueductal grey (vlPAG) or ventral posterolateral nucleus of the thalamus (VPL) by fluorogold (FG) injections into the vlPAG or VPL. C-Fos expression in the DH was induced by injecting 5% formalin into the multifidus (MF, low back) or gastrocnemius-soleus (GS, limb) muscle.

Department of Orthopedics, The Second Affiliated Hospital of Soochow University, Suzhou, Jiangsu, People's Republic of China.
Objective: The incidence of anterior cruciate ligament (ACL) ruptures has been increasing annually. However, clinical surgeons have overlooked the impaction fractures of the posterolateral tibial plateau and lateral femoral condyle in patients with ACL ruptures. The purpose of the present study was to report the detection rate of the posterolateral tibial plateau impaction fractures in patients with ACL ruptures, and to evaluate the functional outcomes of patients following ACL reconstruction (ACLR) without treatment of the tibial fractures at a 2-year postoperative follow-up.

Background: The lateral ankle ligament complex, consisting of the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL), is essential for ankle stability. While the ATFL and CFL are frequently studied, the PTFL's role remains less explored.
Methods: Twelve fresh-frozen ankle specimens were dissected to analyze the PTFL's origin, trajectory, and talar insertion, focusing on its bundles and anatomical relationships.

Background: Posterolateral tibial plateau fractures pose significant challenges for orthopedic surgeons due to the anatomical risks associated with the posterolateral approach. Despite numerous surgical techniques available, there lacks a consensus on the optimal approach.
Methods: Articular line incision approach was employed on 12 patients suffering from posterolateral tibial plateau fractures.
