BACKGROUND Current surgical procedures restoring a dislocated acromioclavicular joint aim to perform an anatomically correct and biomechanically stable reconstruction. However, the coracoidal insertions for the coracoclavicular ligaments have not yet been defined. PURPOSE The objective was to evaluate dimension and orientation of the coracoclavicular(More)
BACKGROUND Tibial plateau fractures requiring surgery are severe injuries. For professionals, amateurs, and recreational athletes, tibial plateau fractures might affect leisure and professional life. HYPOTHESIS Athletic patients will be affected in their sporting activity after a tibial plateau fracture. Despite a long rehabilitation time and program,(More)
The purpose of the current study was to assess the clinical and radiological results after locking T-plate osteosynthesis with coracoclavicular augmentation of unstable and displaced distal clavicle fractures (Neer type 2). Thirty patients, treated between January 2007 and January 2010 were followed up after a median follow-up time of 12.2 months (range(More)
Meniscus tears are frequent indications for arthroscopic evaluation which can result in partial or total meniscectomy. Allografts or synthetic meniscus scaffolds have been used with varying success to prevent early degenerative joint disease in these cases. Problems related to reduced initial and long-term stability, as well as immunological reactions(More)
Fractures of the tibial plateau are among the most severe injuries of the knee joint and lead to advanced gonarthrosis if the reduction does not restore perfect joint congruency. Many different reduction techniques focusing on open surgical procedures have been described in the past. In this context we would like to introduce a novel technique which was(More)
BACKGROUND Fractures of the tibial plateau are among the most severe injuries of the knee joint and are often the result of sports accidents, especially skiing accidents. PATIENTS/MATERIALS AND METHODS Between January 2003 and March 2009, a total of 37 skiers with tibial plateau fractures were treated operatively at Klinikum rechts der Isar, Munich (level(More)
To develop and validate an elbow self-assessment score considering subjective as well as objective parameters. Each scale of the American Shoulder and Elbow Surgeons-Elbow Score, the Broberg and Morrey rating system (BMS), the Patient-Rated Elbow Evaluation (PREE) Questionnaire, the Mayo Elbow Performance Score (MEPS), the Oxford Elbow Score (OES) and the(More)
Optimal surgical treatment of high-grade acromioclavicular joint dislocations is still controversially discussed. The purpose of the present controlled laboratory study was to evaluate whether a polydioxansulfate (PDS®) cord augmentation with separate reconstruction of the coracoclavicular (CC) ligaments and the acromioclavicular (AC) complex provides(More)
The aim of the study was to develop a standardized rat model for chronic rotator cuff tears. Therefore, a time point of degenerative changes that shows comparable histological changes to the chronic tendon tears in humans had to be determined. The rat shoulder has already been described as a standardized model for investigation of the healing behavior in(More)
The purpose was to evaluate histological changes of the supraspinatus tendon (SSP) after refixation under continuous growth factor application over 20 days in comparison to the native healing process. In a chronic rat tendon tear model (15 rats/group), a transosseous SSP refixation was performed and growth factors (control, G-CSF, b-FGF, combination) were(More)
