Safety and efficacy of subcutaneous tanezumab in patients with knee or hip osteoarthritis.

Background/objective: The objective of this study was to investigate the safety and efficacy of subcutaneous (SC) and intravenous (IV) tanezumab administration in osteoarthritis (OA) patients.

Materials And Methods: Study 1027 (NCT01089725), a placebo-controlled trial, evaluated the efficacy of SC tanezumab (ie, 2.5, 5, and 10 mg) and the therapeutic equivalence of 10 mg tanezumab given subcutaneously versus intravenously every 8 weeks in the symptomatic treatment of OA.

Shallow medial tibial plateau and steep medial and lateral tibial slopes: new risk factors for anterior cruciate ligament injuries.

Background: The geometry of the tibial plateau has been largely ignored as a source of possible risk factors for anterior cruciate ligament injury. Discovering the anterior cruciate ligament injury risk factors associated with the tibial plateau may lead to delineation of the existing sex-based disparity in anterior cruciate ligament injuries and help develop strategies for the prevention of anterior cruciate ligament injuries regardless of gender.

Hypothesis: Individuals with a shallower medial tibial depth of concavity, while having increased posteriorly directed slope of their tibial plateau, are at increased risk of suffering an anterior cruciate ligament injury compared with those with decreased posterior slope and increased medial tibial depth.

The geometry of the tibial plateau and its influence on the biomechanics of the tibiofemoral joint.

Background: The geometry of the tibial plateau is complex and asymmetric. Previous research has characterized subject-to-subject differences in the tibial plateau geometry in the sagittal plane on the basis of a single parameter, the posterior slope. We hypothesized that (1) there are large subject-to-subject variations in terms of slopes, the depth of concavity of the medial plateau, and the extent of convexity of the lateral plateau; (2) medial tibial slope and lateral tibial slope are different within subjects; (3) there are sex-based differences in the slopes as well as concavities and convexities of the tibial plateau; and (4) age is not associated with any of the measured parameters.

Posteromedial elbow approach for treatment of olecranon and coronoid fractures.

This article illustrates the posteromedial elbow approach to address both coronoid and olecranon ulnar fractures. Olecranon and coronoid fractures were simulated in 6 cadaveric elbows. The osteotomies were made with a percutaneously placed osteotome through the olecranon fossa and the elbow joint.

The effect of local hematoma blocks on early fracture healing.

To test the effects of lidocaine and bupivacaine on early fracture healing, the tensile strength of five groups of femora from normal rats 14 and 35 days after production of a closed diaphyseal fracture were compared. Data indicate that, in experimental animals injected with local anesthetics at the fracture site, no measurable difference is noted in callus composition, tensile strength, or histological appearance during the early phases of fracture repair prior to callus remodeling.
