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)
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)
Chronic dislocation of the elbow is an exceedingly disabling condition associated with severe instability, limitation of elbow function and significant pain. Due to the potentially conflicting goals of restoring elbow stability and regaining a satisfactory arc of motion, successful treatment is a challenge for the experienced trauma surgeon. We report our(More)
Unilateral external fixation requires an anatomically sound implantation of screws into the upper extremity. Detailed knowledge about the anatomical situation in the areas of pin implantation is of great importance. This paper focuses on relevant anatomical landmarks when implanting screws for external fixation in the humerus, the elbow, the forearm and the(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)
The case of a eleven-year-old girl who had a fracture dislocation of the left elbow with entrapment of the ulnar nerve into the dislocated ulnar epicondyle anlage and unstable forearm fracture of the ipslateral upper extremity is described. This severe injury to the elbow and the ipsilateral forearm is termed "floating forearm" injury. The forearm was(More)
We have evaluated four different fixation techniques for the reconstruction of a standard Mason type-III fracture of the radial head in a sawbone model. The outcome measurements were the quality of the reduction, and stability. A total of 96 fractures was created. Six surgeons were involved in the study and each reconstructed 16 fractures with 1.6 mm(More)
A retrograde nail with posterior-to-anterior (PA) locking into os calcis, talus and tibia was used to correct deformity and achieve fusion after failed fusion. A variety of methods have been published to achieve union of the ankle and subtalar joint in a failed fusion situation. We have studied a retrograde locking nail technique through a 2.5-cm incision(More)
randomised into two treatment groups. In group A 21 patients were treated with cryotherapy. In group B 22 patients were treated with an intermittent compression hand pump. Reduction in swelling of the treated hand and MP and PIP joint movement were recorded with computerised assessment software (EVAL Hand Evaluation System) in comparison to the uninjured(More)
