Low back pain may occur during the weakening process, cracking (stress fracture) or complete fracture.
Of the above group, 25 (89%) patients sustained non-significant stable fractures including 10 anterior compression fractures, eight superior end plate fractures, four transverse process fractures, one spinous process fracture and two other minor abnormalities.
Firstly, the fracture nucleation and growth process under isotropic rock mass conditions is simulated for a circular shaft.
There may be some fractures that cause instability of the ankle including a lateral process fracture of the talus, anterior process fracture of the calcaneus, Jones fracture or Pesudo-Jones fracture (Figure 14).
Fracture morphology is crucial for the clinical decision-making process preceding spinal fracture treatment.
Low porosity and low permeability concrete cubes were employed as caprock analogs to investigate the supercritical CO2 injection-induced fracturing processes under true tri-axial stress conditions.
This paper analyzes delamination processes under modes I and II fracture and fatigue loading for two types of composite materials.
With the increased production of gas from shale in the United States, the process of hydraulic fracturing, or fracking, has come under fire for its potential to pollute the air and contaminate drinking water.
It stripped the Environmental Protection Agency of its authority to regulate a drilling process called hydraulic fracturing.
The waste, from the process called hydraulic fracturing that is used to unlock the gas from shale rock, had been injected under pressure into the well, which is 9,200 feet deep.
