Stürze und sog. Sport assoziierte Verletzungen haben einen Häufigkeitsgipfel in der Adoleszenz, wobei Kontakt- Risikosportarten, z. B. Handball oder Mountain Biken, eine führende Rolle einnehmen. Anderweitige vor allem im häuslichen Umfeld betreffen die ältere Bevölkerung geschlechtsunabhängig. Diese Traumata können für Läsionen des triangulären fibrokartilaginären Komplex (TFCC), Ligamentum lu...

Evidence on the effectiveness of ergonomic interventions to reduce mechanical demands and upper-extremity MSDs is scarce in agriculture. We conducted an intervention to reduce mechanical exposures during manual flower cutting through job rotation, education and reduction of force requirements. One-hundred and twenty workers (20 to 60 years old; 89% women) from six companies that cultivate roses...

PURPOSE Wrist joint-leveling procedures for decompression of the radiocarpal and ulnocarpal joints are accompanied by the risk for subsequent disorders of the adjacent distal radioulnar joint (DRUJ). This study evaluated the dynamic change of the pressure pattern at the DRUJ after joint-leveling procedures. METHODS Thirteen fresh-frozen adult cadaveric upper extremities were used. A segment o...

Knowledge of radial nerve motor branch anatomy is important when performing surgery in its vicinity, neurorrhaphy, and nerve blocks and for understanding the rate and order of recovery of muscle function after injury. Twenty normal fresh cadaver arms were dissected to quantitate radial nerve motor branch anatomy in the forearm. Though variable in individual specimens, innervation order from pro...

BACKGROUND: Muscle fatigue can be defined as the failure of a muscle to maintain a reasonably expected force output. The multivariate approach to fatigue assessment is used because the multiple (EMG) feature provides more information than anyone. OBJECTIVE: This study presents a method of assessing muscle fatigue during endurance testing at 50% maximal voluntary contraction (MVC) using electro...

Twenty canine elbows were examined by low-field MRI. The objective of this study was to compare five magnetic resonance sequences: High Resolution Gradient Echo in the sagittal plane, XBONE T2 in the sagittal plane, Spin Echo T1 in the sagittal plane, Spin Echo T1 in the dorsal plane and 3D SST1 and XBONE T1 in the transverse plane, and to determine which sequences have the highest diagnostic v...

We report the case of a 24-year-old man with a congenital meniscoid articular disc of the triangular fibrocartilage complex with extensor carpi ulnaris tenosynovitis. His young age, the normal articular cartilage, the lack of degenerative changes at the margins of the defect and its bilateral occurrence made this diagnosis likely. A congenital defect of the articular disc of the triangular fibr...

Rheumatoid arthritis commonly affects the distal radioulnar joint (DRUJ). This can result in pain, instability, or tendon rupture. The goals of surgical reconstruction of the DRUJ are to relieve pain, stabilize the joint, and prevent tendon rupture. We review many of the previously described procedures and report our experience with distal ulna excision and soft tissue reconstruction with a dis...
