the posterolateral shearing tibial plateau Fracture Treatment and results via a modified posterolateral approach
Knee, 2008Co-Authors: Donghua Hang, Qiugen Wang, Xiaofeng WuAbstract:Abstract The posterolateral shearing tibial plateau Fracture is relatively uncommon and few studies have concentrated on it so far. The purpose of this study was to review the results of surgical Treatment of this kind of Fracture using a modified posterolateral approach. The clinical results of a case series of 11 patients, collected prospectively, were presented here. At final follow-up 10 out of 11 (91%) patients had satisfactory reduction of the articular surface and all had acceptable alignment. There was neither any loss in reduction or alignment at one year postoperation, with a mean HSS score of 93 (s.d. 3.67, range 84 to 97), nor superficial or deep infections, except that one case had a sanguinous effusion for more than one week postoperatively. It was concluded that the modified posterolateral approach could help to expand the surgical options for an optimal Treatment of this kind of Fracture, and plating of posterolateral shearing Fractures would result in restoration and maintenance of alignment.

Comparison of compression screws used for mandible head Fracture Treatment—experimental study
Clinical Oral Investigations, 2019Co-Authors: Marcin KozakiewiczAbstract:ObjectivesCompression screws that can fix a Fracture of the condylar head of the mandible are available. Although typical titanium lag screws are generally used, a series of headless screws have been designed for this purpose. The “headless” advantage derived from the complete submergence of the screw in the bone after fixation is the lack of irritation of the lateral ligament of the temporo-mandibular joint by the screw head. The aim of this study is to compare the compression force of typically used lag screws with that of newly developed headless compression screws.Materials and methodsThis study tested five types of screws with a 14-mm length: 10 2.0-mm lag screws and 40 headless screws (four groups of equal size: 1.5-mm H screws, 1.8-mm H screws, 2.0-mm H screws, and 1.8-mm W screws). Two cuboid blocks of standardized polyurethane foam were fixed by one screw. The maximal compression force ( F in N) and torque at maximal compression force ( T in Ncm) were tested according to the guidelines of the American Society for Testing and Materials (ASTM F1839-08).ResultsThe test results were as follows: 2.0-mm lag screw: F = 211.5 ± 20.7 and T = 21.1 ± 1.6; 1.5-mm H screw: F = 47.2 ± 5.6 and T = 18.2 ± 1.1; 1.8-mm H screw: F = 95.5 ± 9.8 and T = 18.2 ± 1.1; 2.0-mm H screw: F = 145.1 ± 18.4 and T = 25.5 ± 1.5; and 1.8-mm W screw: F = 180.5 ± 8.7 and T = 26.4 ± 2.8. Each type of screw significantly differed from one another as far as compression forces ( F ) were considered ( p

Significance of osteoporosis in craniomaxillofacial surgery: A review of the literature
Osteoporosis International, 2006Co-Authors: B. Hohlweg-majert, Rainer Schmelzeisen, B. M. Pfeiffer, E. SchneiderAbstract:Osteoporosis is a common problem in orthopedic surgery. The purpose of this review of the literature was to examine whether osteoporosis is also an important factor in patient Treatment in the field of craniomaxillofacial surgery. Emphasis was given to the consequences of osteoporosis for the maxilla and mandible, the influence of osteoporosis on Fracture Treatment, the use of dental implants, the importance of soft tissues and the effect of osteoporosis therapies. It was found that osteoporosis does affect the bones of the skull. The effect of osteoporosis on Treatment, however, is controversial and necessitates better ways of quantifying bone loss. Large inter-individual and site-specific differences in bone density, as well as other effects such as removal of teeth, periodontitis, implant insertion, augmentation procedures and altered loading with dystrophic consequences need to be considered in future studies. Special attention should be given to osteoporosis during Fracture Treatment.

animal models for Fracture Treatment in osteoporosis
Osteoporosis International, 2005Co-Authors: Marcus Egermann, Joerg Goldhahn, E. SchneiderAbstract:Demographic changes in the age structure of occidental populations are giving rise to osteoporosis and associated Fractures, which are becoming a major public health burden. Various animal models have been established and used to investigate the pathogenesis of osteoporosis and to facilitate the preclinical testing of new Treatment options such as antiresorptive drugs. Although osteoporosis can be induced in animals, spontaneous Fractures without adequate trauma were only found in nonhuman primates. An animal model designed to investigate new ways to treat Fractures of osteoporotic bone has to fulfill requirements that are very different from those of pharmacological testing. The aspects of major interest in orthopedic applications are bone fragility, efficacy of implant fixation and bone healing. Existing animal models for osteoporosis were critically reviewed focusing on these aspects. The advantages and disadvantages of the models with regard to their application in the testing of new Fracture-fixation devices or biological approaches to stimulate bone healing are discussed. Ovariectomy alone does not cause the bone loss seen in osteoporotic human patients. New models to simulate Fracture of osteoporotic bone need to be explored and used to address the specific aims of an experiment.
