Distal tibia allograft for glenohumeral instability: does radius of curvature match?

Background: A distal tibia osteochondral allograft is a potential graft option for glenoid reconstruction because the distal tibia may have a similar radius of curvature (ROC) as the glenoid. This study evaluated ROC mismatch as measured on computed tomography (CT) scans between the glenoid, distal tibia, and humeral head.

Methods: Bilateral CT images were formatted for 10 decedents from the Office of the Medical Investigator database, giving 20 specimens per anatomic location.

Severity of Asynchronous Slipped Capital Femoral Epiphyses in Skeletally Immature Versus More Skeletally Mature Patients.

Background: Routine prophylactic screw fixation for skeletally immature patients with slipped capital femoral epiphysis (SCFE) continues to be debated. The purpose of this study was to assess the slip severity of a second SCFE in skeletally immature versus more mature patients and determine necessity of contralateral hip prophylactic screw fixation.

Methods: All patients treated for SCFE at 3 pediatric hospitals over a 10-year time period (January 1, 2002 to December 31, 2011) were evaluated.

Suture-button versus screw fixation of the syndesmosis: a biomechanical analysis.

Background: The treatment of ankle fractures with syndesmotic injuries associated with disruption of the deltoid ligament complex is controversial. The purpose of this study was to compare both the biomechanical and physiologic properties of suture-button fixation to the intact syndesmosis and screw fixation.

Materials And Methods: Eight fresh frozen human cadaveric ankles were used in three different groups.

[Gastroenterology - accusations and errors in treatment: evaluation of the completed expertise process in internal medicine of the expert committee of North Rhineland for the years 2001 to 2005].

Since three decades the extrajudical expertise procedures of the Expert Committee and Arbitration Group has served to pacify the doctor-patient relationship. Systematic analyses of accusations and errors provide valuable data that help to avoid treatment errors and liability disputes against physicians. Disease of the gastrointestinal tract were found ex post to be the main diagnosis in 10 % of the patients entering complaints.

Binding of mannose-functionalized dendrimers with pea (Pisum sativum) lectin.

Lectins are invaluable tools for chemical biology because they recognize carbohydrate arrays. Multivalent carbohydrate binding by lectins is important for processes such as bacterial and viral adhesion and cancer metastasis. A better understanding of mammalian lectin binding to carbohydrate arrays is critical for controlling these and other cellular recognition processes.
