STUDY DESIGN A new rabbit model was developed that produces disc degeneration through the application of controlled and quantified axial mechanical load. OBJECTIVES To characterize the changes associated with disc degeneration, and to evaluate the feasibility of local transfer of agents to the compressed discs to stimulate disc regeneration. SUMMARY OF(More)
The distal radioulnar joint (DRUJ) plays a tremendous role regarding the functionality of the upper extremity. Lesions of the DRUJ can limit the functionality of the upper extremity decisively. Many clinical and radiological procedures are used to diagnose instability of the DRUJ. Up to now, there has not been a general consensus concerning the(More)
INTRODUCTION Sulcus ulnaris syndrome is the second most common neurocompression syndrome in the upper limb after carpal tunnel syndrome. Its severity can be appreciated by the Dellon Classification. We present our experience and results after endoscopic decompression. PATIENTS AND METHODS A retrospective chart review of 55 patients operated over a 3-year(More)
STUDY DESIGN An in vivo study on the rabbit lumbar spine model. OBJECTIVES Effects of temporary dynamic distraction on intervertebral discs were studied on the lumbar spine rabbit model to characterize the changes associated with disc distraction and to evaluate feasibility of temporary disc distraction to previously compressed discs in order to stimulate(More)
Cell therapy seems to be a promising way to reconstitute degenerated discs. We elucidate the basic aspects of intervertebral disc (IVD) cell therapy to estimate its potential in disc regeneration. Cell transfer efficiency and survival was quantified by luciferase expression after injection of recombinant cells into healthy, nucleotomized or mechanically(More)
Bennett fractures are unstable, and, with inadequate treatment, lead to osteoarthritis, weakness and loss of function of the first carpometacarpal joint. This study focuses on long-term functional and radiological outcomes after open reduction and internal fixation. Between June 1997 and December 2005, 24 patients with Bennett fractures were treated with(More)
BACKGROUND Skin defects of the foot, ankle and distal lower leg often require coverage by local or distant flaps. We aimed to compare functional outcome and donor-site morbidity following transfer of distally based delayed sural (DSFs) or peroneus brevis flaps (PBFs). METHODS Between 2003 and 2006, 52 patients (24 DSFs and 28 PBFs) were included. For(More)
Dynamic external fixation systems are considered as optimal devices for treatment of fracture dislocations of the proximal interphalangeal joint (PiP). The pins and rubbers traction system (PRTS) is cheap, easy to assemble and comfortable and allows early mobilization of the affected digit. We investigated the influence of different wire positions and(More)
Intraartikuläre Frakturen an der Basis des 1. Mittelhandknochens sind häufig, ihre Behandlung kontrovers. Eine Ausheilung in Fehlstellung kann zu posttraumatischer Rhizarthrose mit Beeinträchtigung der gesamten Handfunktion führen. 1994–1999 wurden 30 Frakturen der Metakarpale-I-Basis (24 Bennett-, 3 Rolando- und 3 Trümmerfrakturen) an der Klinik für Hand-,(More)
Die Behandlungsergebnisse von Mittelgelenkfrakturen sind oftmals nicht befriedigend für den Patienten und den Chirurgen, da vor allem konservative Methoden die Einsteifung des Gelenks nicht verhindern können. Daher wird die frühfunktionelle Therapie mit externen Fixateuren zunehmend favorisiert. Sie kombiniert das Prinzip der Ligamentotaxis mit der(More)
