Injury to the anterior cruciate ligament (ACL) is regarded as critical to the physiological kinematics of the femoral-tibial joint, its disruption eventually causing long-term functional impairment. Both the initial trauma and the pathologic motion pattern of the injured knee may result in primary degenerative lesions of the secondary stabilisers of the(More)
BACKGROUND Elbow contracture is a recognized sequela of elbow injuries in children and adolescents, but previous studies of operative treatment with formal capsular release have demonstrated unpredictable outcomes and unfavorable results. METHODS Over a period of five years, fourteen children and adolescents with a mean age of fourteen years who had(More)
A stiff elbow is usually defined as having less than 30 degrees in extension or flexion less than 130 degrees. Most activities of daily living are possible if the elbow has a range of motion of 100 degrees (30-130 degrees of flexion, Morrey's arc of motion). Loss of motion of the elbow is not uncommon after trauma, burns, or coma and severely impairs upper(More)
Side-to-side comparison of anatomical or functional parameters in the evaluation of unilateral pathologies of the human knee joint is common practice, although the amount of symmetry is unknown. The aim of this study was to test the hypothesis that there are no significant differences in the morphometric knee joint dimensions between the right and the left(More)
Post-traumatic stiffness of the elbow joint is a frequent result of immobilisation leading to severe disability in the use of the upper extremity. Recognition of the tendency to stiffness leads to the assumption that the strong self-healing forces of the capsule and ligament apparatus converts the initial instability of the joint after ligament disrupture,(More)
External fixation for fractures of the distal radius has been used for almost 80 years. The main objective is to gain reduction and maintain the reduction throughout the treatment period. Several fixator concepts are available and selection is based on the complexity of the injury to be treated as well as the surgeon's experience. Periarticular application(More)
New techniques for tibiotalocalcaneal arthrodesis ideally should improve union rate and reduce the complication rate. The purpose of this study was to evaluate the union rate of tibiotalocalcaneal arthrodesis achieved using an intramedullary nail without formal debridement of the subtalar joint and open or percutaneous debridement of the ankle joint.(More)
Traumatic dislocation of the hip joint is an uncommon injury in children. The present report on this traumatic emergency is based on the authors' own observations of three cases and a review of the literature. The main problem is the possible development of avascular necrosis of the femoral head. The crucial therapeutic intervention to avoid this serious(More)
Zur Behandlung der Ellenbogensteife wird die Distraktionsarthrolyse mit Fixateur externe und nachfolgender fixateurgestützter Mobilisation beschrieben. Die Gelenkdistraktion wird zur allmählichen Dehnung der geschrumpften Kapsel-Band-Strukturen eingesetzt und erlaubt die sichere Separation der Gelenkflächen. Nach der intraoperativen Distraktion folgt eine(More)
Open surgical reconstruction of the lateral ulnar collateral ligament is the standard treatment for symptomatic posterolateral rotatory instability of the elbow. It involves dissection and retraction of the lateral elbow muscles, which have been shown to be secondary stabilizers of the lateral elbow. We introduce a new muscle-protecting technique for(More)
