Introduction Indirect ballistic fractures occur when a projectile passes close to, but not contacting, the bone. The mechanism of how these fractures occur is not yet proven, but recently the acoustic shockwave has been excluded as a cause. The objective of this study is to determine whether the expanding temporary cavity, the collapse of this cavity or its oscillation causes these fractures. In addition, we describe the fracture morphology and biomechanical causes of this injury. Method 40… Expand
Clothing increases the risk of indirect ballistic fractures
TLDR
Clothing increases the risk of indirect fracture and results in larger, more superficial temporary cavities, with greater lateral pressures than are seen in unclothed specimens, resulting in more comminuted fractures. Expand
Evaluation of bone surrogates for indirect and direct ballistic fractures.
TLDR
An ideal bone surrogate for ballistic testing was not identified and future work is warranted, but fractures patterns were found to be comparable to the PMHS for tests conducted with Synbones, however the input parameters were slightly varied to produce similar results. Expand
Interpretation of long bones ballistic trauma.
TLDR
This work has applied the previously established fundamentals of ballistic injury to cranial bones to the tubular structures on long bones and concludes that the physics of ballistic penetration are constant and the material properties of cranial and tubular bone seem similar. Expand
[Ballistic concepts and management of gunshot wounds at members].
TLDR
The management of trauma in the C.H.U. Saint-Pierre hospital appears not optimal in light of the literature especially in terms of setting the vascular point of debridement, antibiotic and nerve repair resulting in significant consequences. Expand
The use of gelatine in wound ballistics research
TLDR
Key messages are that test variables, projectile type, impact site on the body and intermediate layers (e.g. clothing, personal protective equipment (PPE)) can affect the resulting wound profiles. Expand
Skin and skin simulants
TLDR
The variability of commonly used simulants for human skin such as various types of leather could impact on the confidence of any reconstruction study data obtained by using such simulants, particularly with reference to reconstruction studies that consider injury to humans. Expand
Physical Models: Tissue Simulants
The most common manner of reproducing the effects of energised fragments penetrating human tissues is to use a physical model as a tissue simulant. Such physical models encompass simulants includingExpand

Ballistic fractures: indirect fracture to bone.
TLDR
In this study, indirect fractures were produced after passage of the projectile, indicating that the temporary cavity, not the sonic wave, was responsible for the indirect fractures. Expand
Blast-related fracture patterns: a forensic biomechanical approach
TLDR
Tertiary blast effects were the predominant mechanism of injury, with severe axial loading to the lower extremity being a characteristic of the fractures seen, and clearly demonstrate two distinct injury groups based upon the casualties' environment. Expand

TLDR
A patient with a high-velocity wound with limited soft tissue disruption, no significant functional deficits, no evidence of bullet fragmentation, and minimal bony involvement can be a candidate for simple wound care. Expand
High velocity missile injury. An experimental study of the retentive forces of tissue.
TLDR
Wound ballistics is defined as the study of the motion of missiles within the tissues and tissues with a more cohesive structure and with large amounts of elastic tissue consequently demonstrate a greater resistance to injury. Expand
Joint and long-bone gunshot injuries.
TLDR
Gunshot fractures are an important consideration for orthopaedic surgeons not only because of their frequency, but also because of the amount of resources that must be provided to care for each patient. Expand
Improved characterization of combat injury.
TLDR
These new tools have been successfully implemented to describe combat injury, mortality, and distribution of wounds and associated injuries and SWM has brought data from all three combat registries together into one analyzable database. Expand
The relationship between mechanisms of wounding and principles of treatment of missile wounds.
TLDR
Although extremity wounds from high-velocity projectiles may heal uneventfully, surgical exploration is indicated whenever there is a possibility of subfascial penetration, and obviously devascularized tissue should be excised. Expand

A primary objective of this experimental investigation was to further understand relationships among loading characteristics as they affect the resultant fractures of human long bones (tibia, femur,Expand

TLDR
Research on pressure waves near the wound tracks, generated by spherical fragments, and the zones of indirect bone fractures generated by pressure waves of impact are reported. Expand
