“…This technique is required to prevent serious head contact with the ground in judo. Previously, in most studies on head injuries, linear acceleration has been used to quantify external forces (12). However, it is unlikely that head acceleration in response to a judo throw is isolated to ei- az from 17.7 to 20.0 G using Osoto-gari.…”

Biomechanical analysis of acute subdural hematoma resulting from judo

This study investigated biomechanical mechanisms of acute subdural hematoma caused by judo and sought preventive measures to reduce injury. A Japanese judo expert repeatedly threw an anthropometric test device using two throwing techniques, Osoto-gari and Ouchi-gari. Linear and angular accelerations of the head were measured. Both throwing techniques resulted in the dummy falling backwards, with the occipital area of the head contacting the mat, and peak linear and angular accelerations being observed when the head contacted the mat. For linear acceleration, the posterior-anterior direction showed the greatest force (41.0 ± 2.6 G using Osoto-gari, and 86.5 ± 4.3 G using Ouchi-gari). For angular acceleration, values for sagittal plane rotation were greatest among the three directions measured (3315 ± 168 rad/s 2 using Osoto-gari, and 1328 ± 201 rad/s 2 using Ouchi-gari). We concluded that occipital head contact produced the most forceful longitudinal linear and sagittal plane angular accelerations; subsequent stretches and ruptures of parasagittal bridging veins resulting in acute subdural hematoma. As severe head injuries can result if a person's head comes into contact with the mat, offensive throwing techniques should be restricted to participants able to sufficiently demonstrate the Ukemi technique.

“…Three-dimensional analysis of the trajectory movement of each of the soldiers enables the probable dysfunction of the cervical spine caused by extortion as an IED explosion to be specified. The cervical spine is particularly susceptible to damage when the corps of the body relative to the neck is subjected to sudden acceleration or deceleration (Schmitt et al, 2010, Cronin, 2011. The results obtained in the course of research allow for the classification of cases with soldiers in two groups.…”

Abstract:As a result of an explosion under a military vehicle, the risk of threat to life and health of the crew increases. Examination of this event in terms of the security of soldiers comes down to a complex analysis of the mutual interaction of the body of a soldier, seating and structural elements of the vehicle. As a result, shock wave impacts can cause tremor resulting from the construction of the vehicle and acceleration of the passenger's body. This study attempts to analyze the impact of an explosion of an improvised explosive device (IED) under the military vehicle with the risk of cervical spine injuries of soldiers. The analysis was carried out using numerical methods in the LS-DYNA program and was carried out taking into account the variable displacement values and acceleration recorded during the\ explosion. The study used a model of the body of a soldier in the form of a Hybrid III 50th Male Dummy.

Interpretation of juvenile trauma requires understanding of biomechanical and remodeling factors, as well as the dynamics of the growth process. Although terminology relating especially to biomechanical factors can be complex, use of proper terms is essential to avoid misunderstanding. Analysis can include direct observation, individual history documentation, radiography, microscopy, and bone scintigram study. In addition to the appearance of the trauma, relevant observations include the type and area of bone involved, age of the individual, and possible evidence of repair. Such analysis can elucidate the nature of juvenile trauma and facilitate interpretation of the timing of fracture events.
