inclination angle in Greenstick Fracture of mandibular subcondyle treated with intermaxillary fixation in an elderly patient
Plastic and reconstructive surgery. Global open, 2021Co-Authors: Kun Hwang, Sung HwanAbstract:This study presents the outcomes of a conservative approach to Greenstick condylar Fracture treatment in an elderly patient. Serial changes of the inclination angle were measured in a Greenstick Fracture of the mandibular subcondyle treated with intermaxillary fixation (IMF). A 64-year-old woman presented to an outpatient clinic complaining of pain on her chin. While waiting for an elevator, she lost consciousness and hit her face on the floor. She had a limited mouth-opening of 13 mm. Panoramic radiography and computed tomography confirmed a Greenstick (incomplete) Fracture of the left condyle, in which the lateral side of the bone was Fractured and the medial side was bent. The medial inclination was approximately 40.4 degrees. On the second post-trauma day, IMF was performed using arch-bars and a prefabricated occlusal stop. Serial Towne's views were taken. The inclination of the Fractured condyle was measured and compared with the contralateral side. The difference in inclination angles (DI) between the Fractured and contralateral sides was plotted over time. In SPSS version 19.0, an exponential regression model was constructed. In this patient, a Greenstick (incomplete) Fracture of the condyle (40.4 degree inclination) was treated with IMF and a pre-fabricated occlusal stop. On day 42 post-IMF, the inclination angle had decreased to 15.6 degrees, only 5.4 degrees greater than the contralateral side. The DI was fitted to exponential regression model (y = 25.111e-0.028x, P = 0.004). This case shows that even in an elderly patient, a Greenstick Fracture of the mandibular condyle can be treated by vertical lengthening using an occlusal stop and IMF.

change of the inclination angle in a Greenstick Fracture of the mandibular subcondyle treated with intermaxillary fixation in a child
Journal of Craniofacial Surgery, 2021Co-Authors: Kun Hwang, Sung HwanAbstract:ABSTRACT This paper presents the outcomes of a conservative approach to Greenstick condylar Fracture treatment in a child. Serial changes of the inclination angle were measured in a Greenstick Fracture of the mandibular subcondyle treated with intermaxillary fixation (IMF).A 7-year-old girl presented with the complaint of pain on her chin. She had fallen from a 3-m height and hit her face on the floor. She had limited mouth-opening of one finger breadth. Panoramic radiography and computed tomography confirmed a green-stick (incomplete) Fracture of the right condyle, in which the lateral side of the bone was Fractured and the medial side was bent. The medial inclination was approximately 67.9°. On the second posttrauma day, IMF was performed using arch-bars and a prefabricated occlusal stop. Serial Town's views were taken. The inclination of the Fractured condyle was measured and compared with the contralateral side. The difference in inclination angles (DI) between the Fractured and contralateral sides was plotted over time. In SPSS version 19.0, an exponential regression model was constructed.In this child, a green-stick (incomplete) Fracture of the condyle (68.0° inclination) was treated with IMF and a prefabricated occlusal stop. On day 321 post-IMF, the inclination angle had decreased to 31.1°, only 6.8° greater than the contralateral side. The DI was fitted to an exponential regression model (y = 37.019e-0.006x, R2 = 0.703, P < 0.001).This case shows that even in children, a Greenstick Fracture of the mandibular condyle can be treated by vertical lengthening using an occlusal stop and IMF.

La Ferrassie 1: New perspectives on a "classic" Neandertal.
Journal of Human Evolution, 2018Co-Authors: Asier Gómez-olivencia, Nohemi Sala, Morgane Bardey, James C. Ohman, Rolf Quam, Antoine BalzeauAbstract:Abstract The La Ferrassie 1 (LF1) skeleton, discovered over a century ago, is one of the most important Neandertal individuals both for its completeness and due to the role it has played historically in the interpretation of Neandertal anatomy and lifeways. Here we present new skeletal remains from this individual, which include a complete right middle ear ossicular chain (malleus, incus, and stapes), three vertebral fragments, and two costal remains. Additionally, the study of the skeleton has allowed us to identify new pathological lesions, including a congenital variant in the atlas, a Greenstick Fracture of the left clavicle, and a lesion in a mid-thoracic rib of unknown etiology. In addition, we have quantified the amount of vertebral pathology, which is greater than previously appreciated. We have complemented the paleopathological analysis with a taphonomic analysis to identify any potential perimortem Fractures. The taphonomic analysis indicates that no surface alteration is present in the LF1 skeleton and that the breakage pattern is that of bone that has lost collagen, which would be consistent with the intentional burial of this individual proposed by previous researchers. In this study, we used CT and microCT scans in order to discover new skeletal elements to better characterize the pathological lesions and to quantify the Fracture orientation of those bones in which the current plaster reconstruction did not allow its direct visualization, which underlines the broad potential of imaging technologies in paleoanthropological research. A century after its discovery, LF1 is still providing new insights into Neandertal anatomy and behavior.

mri of posttraumatic cyst like lesions of bone after a Greenstick Fracture
European Radiology, 1997Co-Authors: Hans Roland Durr, A Lienemann, Axel Stabler, J H Kuehne, H J RefiorAbstract:Posttraumatic bone-cyst formation is a known but rare process. Typical location is the distal radius, usually as a result of a Greenstick Fracture. The pathogenesis is unknown; however, subperiosteal migration of fat or hemorrhage with later absorption may cause cyst formation. We present the first reported case of MR imaging of this lesion. At MRI subperiosteal hemorrhage was found to be the cause of cyst formation.
