Review Case ReportsBrachial artery injury in closed elbow dislocation. Case report and review of literature.
A case of elbow dislocation with injury to the brachial artery is described. The rarity of the complication makes the treatment controversial. Conservative treatment should be the first line of management of this vascular complication.

To realize the new concept of biological internal fixation the limited contact dynamic compression plate was developed. It minimizes vascular damage to the plated bone segment. It should lead to a more versatile and efficient application of internal fixation using plates.

Case ReportsDigital subtraction angiography in musculoskeletal tumors and other conditions.
One hundred and forty consecutive DSA examinations of various musculoskeletal diseases were analyzed with respect to the contributions and/or limits of this modern diagnostic imaging modality. Angiography remains the imaging tool of choice for many benign and malignant orthopedic conditions of bones and soft tissues, mainly when MRI is still not generally available. ⋯ DSA has the advantage of being less invasive and it also surpasses analog arteriography in better visualization of vascular patterns hidden in hyperostosis, sclerosis, and metallic shadows. Angiographic investigations, when necessary, should therefore start with DSA.

Comparative StudySignificance of postoperative stability for bony reparation of comminuted fractures. An experimental study.
The significance of postoperative mechanical stability to bone repair of comminuted fractures was investigated in an animal experimental study comparing four commonly employed operative methods of fracture stabilization: 1. Plate osteosynthesis combined with lag screw fixation; 2. Bridging plate osteosynthesis; 3. ⋯ As fracture model, a triple wedge osteotomy of the right sheep tibia was used. In regard to biomechanical strength, the method which gave best postoperative stability, plate osteosynthesis in combination with interfragmentary lag screws, did not result in the best bone repair. In this experimental setup, stabilization by bridging methods, inducing bone healing by secondary intention, gave better bone regeneration in the experimental fractures.

Case ReportsBilateral pseudarthrosis of the femur after stress fracture.
Stress fractures of the diaphysis of the femur are very rare, particularly bilateral ones. We describe here a woman patient with bilateral pseudoarthrosis of the femoral diaphysis which was the result of a stress fracture. ⋯ The patient has been closely examined for over 30 years. Our own explanation for the beginnings of stress fracture as well as for the pseudarthrosis development are given.
