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)
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)
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)
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)
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)
For osteosynthesis in the epiphyseal region of long bones, specialized screw types are available to achieve a better purchase in cancellous bone. Typically, the cancellous bone screw has a large outer thread diameter with a relatively small core diameter and a great pitch. Due to its dimensions, this screw type is not suited for the cancellous bone areas in(More)
Delayed ruptures of the extensor pollicis longus tendon (EPL) occur in about 0.7 percent following undisplaced distal radius fractures. Two possible mechanisms are mainly discussed in the literature: A mechanical irritation of the tendon caused by a sharp edge of the fractured bone and a direct microvascular compromise of the poorly vascularized tendon. In(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)
We describe a case of a femoral neck fracture occurring 51 years after a hip arthrodesis. This rare lesion in an obese woman was treated with a straight supracondylar nail with proximal and distal locking inserted retrograde from the subtrochanteric area into the ileum. Full weight bearing was achieved within 1 week postoperatively, and union was present 3(More)
