The effects of body fat percentage on inter-vertebral spinal mobility control from hyperextension spinal orthoses
Hyperextension spinal orthoses are common modalities in treating vertebralfractures. Their objective is to retain the spine in a hyperextended position tooffload the fractured vertebra(e) and allow healing. To date, accurate insight intothe efficiency of hyperextension spinal orthoses is absent. In …

Thermo-tectonic record of hyperextension, structural inversion, and foreland basin evolution of the eastern and central Pyrenees
… This work constrains the Early Cretaceous hyperextension history along the Iberia-European margin and how rift inheritance affected the structural and foreland basin evolution of the Late Cretaceous-Oligocene Pyrenean orogeny. Chapters 1 and 2 aim to understand the thermal and structural …

Upper Extremity Interaction with a Helicopter Side Airbag: Injury Criteria for Dynamic Hyperextension of the Female Elbow Joint
… side airbag system and to develop dynamic hyperextension injury criteria for the female elbow joint. Part I involved a series of 10 experiments with an original Army Black Hawk helicopter side airbag. A 5th percentile female Hybrid III instrumented upper extremity was used to demonstrate …

French osteotomy for cubitus varus in children: a long term study over 27 years
… have been described to correct the associated hyperextension and internal rotation deformities and to prevent a prominent lateral condyle. Methods: We retrospectively reviewed 90 consecutive patients (1986-2012). The mean age of the patients at surgery was 8.2 years (3 to14 years). The varus …

The Effect of Stifle Angle on Stifle Kinematics following TPLO: An in vitro Experimental Analysis
… in any of the three conditions from 120° – 137°. Hyperextension values did not differ significantly between conditions. Conclusion: Data from this biomechanical model suggests that the TPLO fails to neutralize CTT throughout a loaded range of motion. Internal rotation and hyperextension values …

Assessment of fetoscopic tracheal occlusion using ultrasound images in phantom study
… vertebrae stress and fetal distress that the hyperextension could cause to the fetus. The fetal neck positions throughtout the surgery were assessed and measured by means of ultrasound images. The results show that the babies undergo a neck hyperextension of great magnitude that undoubtedly …

The effectiveness of a splint programme in preventing the deterioration of already evident swan neck and boutonniere deformities in patients with rheumatoid arthritis
… the splints were included. For the study the PIP hyperextension splint and the three-point-PIP extension splint was chosen for the swan neck and boutonniere deformities respectively. Patients were followed up for one year. Results were marginally positive for the prevent ion of swan neck …

Upper extremity vertical ground reaction forces during the back handspring skill in gymnastics: A comparison of various braced vs. unbraced techniques
… with the common mechanism of repetitive hyperextension in weight bearing among gymnasts of all ages. Many gymnasts use wrist supports as prevention; however, literature regarding their ability to reduce injury is not well described. The purpose of this study is to evaluate the effects of …
